Description

  The present invention relates to a portable electronic device with a power generation function and a method for controlling a portable electronic device with a power generation function.

Watches with a power generation function have come to be widely used because they have the advantage of not requiring battery replacement.
In an electronic timepiece with a power generation function, the electric power generated by the power generation means is used by charging the power storage means. Therefore, when power is not generated, the pointer is moved using the electric power stored in the power storage means.

  In such an electronic timepiece with a power generation function, when the voltage of the power storage means is low, the timepiece movement is stopped, and when the power generation state is detected when the movement is stopped, the initial voltage at that time is detected, and the initial voltage is set in advance. In the case where the voltage is higher than the set operation restart voltage, there has been known one that improves convenience by continuing to move the hand for a predetermined time even when power generation is stopped thereafter (Patent Document 1). reference).

JP 2011-149848 A

  However, after restarting the operation because power generation was detected, even if the electronic device is hardly used, the hand movement is continued until a predetermined time elapses, so there is a possibility that the power of the power storage means is wasted. .

  It is an object of the present invention to provide a portable electronic device with a power generation function and a method for controlling a portable electronic device with a power generation function that can suppress wasteful power consumption of a power storage unit.

  The present invention includes a power generation unit, a power storage unit that stores electrical energy generated by the power generation unit, a device that is operated with the electrical energy stored in the power storage unit, and a power generator to the power storage unit. A portable electronic device with a power generation function that is used in a portable manner, comprising charge detection means for detecting a charge state and operation control means for controlling the operation state of the device, wherein the operation control means An operation stop unit that controls to an operation stop state, an operation restart unit that restarts the operation of the device when the device is in an operation stop state, and an operation duration of the device can be set, and the remaining time A timer that counts time, a portable amount detection unit that detects a portable amount when the operation of the device is resumed, and an operation duration adjustment unit that adjusts the operation duration of the timer when the operation of the device is resumed. The operation stop unit controls the device to the operation stop state when the remaining time of the timer becomes 0, and the operation restart unit detects the charge state by the charge detection means. The driving duration adjustment unit sets the driving duration in the timer when the carrying amount detected by the carrying amount detection unit reaches a predetermined value.

  According to the present invention, the portable amount detection unit and the operation duration adjustment unit are provided, and when the charge state is detected and the operation is restarted from the operation stop state, it is confirmed that the portable amount has reached a predetermined value. The operation duration corresponding to the amount of mobile phone is set in the timer. Here, the carrying amount is a parameter corresponding to the length of time during which it can be determined that the user is carrying and using the portable electronic device with the power generation function. Specifically, when the power generation means generates power in a portable state, the amount of portable power can be obtained from the time during which the power generation means charges the power storage means. Further, in the case where power can be generated by vibrating a portable electronic device with a power generation function, the amount of mobile can be obtained by counting the amount of vibration. That is, the amount of carry can be detected in terms of the amount of power generated when the device is carried, as well as the time it is actually carried.

  According to the present invention, when the operation is restarted by the charge detection, the portable amount detection unit detects the portable amount. Then, after the portable amount becomes a portable amount longer than a predetermined value, for example, 6 hours, and it becomes possible to determine that the user is carrying and using the electronic device, the driving duration adjusting unit determines the predetermined amount. The operation duration of is set. Therefore, it is possible to prevent a long operation duration from being set only by temporary charge detection, and it is possible to prevent wasteful consumption of the electric power of the power storage means.

  In the present invention, a voltage detection unit that detects a voltage of the power storage unit is provided, and the operation duration adjustment unit detects the operation duration set in the timer, the detected voltage detected by the voltage detection unit, and the portable amount It is preferable to set a plurality of levels based on the above.

  If the driving duration adjusting unit can set the driving duration set in the timer in a plurality of stages based on the detected voltage and the amount of portable, it has an appropriate length compared to the case of setting in one stage. Can be set to operation duration

  In the present invention, it comprises voltage detection means for detecting the voltage of the power storage means, the operation duration is set for each of a plurality of voltage ranges divided in advance, and the operation restarting unit is charged by the charge detection means When the detected voltage detected by the voltage detecting means corresponds to the first voltage range corresponding to the shortest operation duration, the timer is set to the shortest operation duration, and the detected voltage However, when it corresponds to a voltage range higher than a 1st voltage range, it is preferable to operate the said operation duration adjustment part.

According to the present invention, when the operation duration can be set in a plurality of stages according to the voltage range corresponding to the detected voltage, when setting the operation duration other than the shortest operation duration, The operation duration adjustment unit is operating.
If the operation duration is set according to the detected voltage, even if power is generated temporarily in a portable operation, if the voltage of the storage means during operation is high, the operation duration is set to a long time, which is useless. Consume power.
On the other hand, in the present invention, even if the detected voltage is a voltage level that can be set other than the shortest operation duration, the operation duration is not set until the carrying amount reaches a predetermined value. It is possible to prevent a long operation duration from being set, and to suppress wasteful power consumption.

  In the present invention, the portable amount detection unit divides a day into a plurality of time regions starting from when the operation is resumed, and when the charging state is detected a plurality of times by the charge detection means in the time region, the portable region detection unit carries the time region. It is set in the state detection time range, and it is determined that there is a carry amount for one day when there are more than a predetermined number of carry state detection time ranges in the day, and the driving duration adjustment unit When the number of days reaches a predetermined value, it is preferable to set the operation duration in the timer.

In the present invention, when the portable amount detection unit divides a day into a plurality of time ranges and detects the state of charge a plurality of times in each time range, the time range is determined as a portable state detection time range in which the electronic device is carried. Is set. For this reason, it is possible to reduce the possibility of erroneously determining charge detection by a single operation that changes the location of the electronic device as being carried.
Furthermore, since it is determined that there is a carry amount for one day when a predetermined number or more of carry state detection time zones exist, the carry state of the user can be more accurately determined. That is, when the user carries the electronic device, the charging state can be detected by carrying it for about 7 hours in consideration of the general activity time of the user. For this reason, if the time length of the time zone is set to 3 hours, if the carrying state is detected in the three time zones, it means that the electronic device is carried for 7 hours or more, that is, the carrying amount for one day. It can be correctly determined that there is.
In the present invention, when the portable amount detected by the portable amount detection unit reaches a predetermined value set in advance, such as 2 days or 7 days, by setting a timer to an operation duration corresponding to the predetermined value, for example, If the carrying amount is 2 days, the driving duration can be set to 7 days, and if the carrying amount is 7 days, the driving duration can be set to 30 days.

In the present invention, the charge detection unit is configured to be able to detect a continuous charge state from the power generation unit to the power storage unit, and the portable amount detection unit has a detection time length of the continuous charge state. It is preferable to detect the carrying amount based on this.
The continuous detection of the charging state means, for example, a case where the charging state can be continuously detected at the charging detection timing at intervals of 1 second when charging detection is performed at intervals of 1 second. That is, it may be determined that a continuous state of charge is detected when the time during which charging cannot be detected has not continued for a set time or longer. Therefore, when the power storage means is rapidly charged using a charger, or when the power generation device is operated by manual operation or the like to rapidly charge the power storage means, a continuous charge state is detected.

According to the present invention, the portable amount detection unit detects the portable amount based on the length of time during which a continuous charge state is detected by the charge detection unit. Then, the driving duration adjusting unit sets the driving duration according to the amount of the mobile phone, that is, the length of the continuous charging state detection time.
For example, when equipped with self-winding power generation means using a rotating weight that can generate power by hand gesture operation, when the user is charging quickly by intentionally performing hand gesture operation, or when charging rapidly using a charger In addition, by detecting the charging time, the carrying amount can be detected appropriately. That is, the self-winding power generation means using a rotating weight automatically generates power without being conscious of it if the user carries it, while the user intentionally performs a hand gesture operation to generate power. You can also For example, the amount of power generation corresponding to self-winding power generation when carried around for a day can be obtained by intentionally shaking hands continuously for several minutes by the user. Therefore, when the user resumes driving, for example, when the user performs a hand gesture operation corresponding to, for example, one day or seven days, the driving duration can be increased to a long time, and convenience can be improved.
Similarly, when charging is performed using a charger that generates a magnetic field and generates a current in the power generation coil of the power generation means to charge the power storage means, the charge amount corresponding to one day or seven days (power generation amount) ) Is set by the user so that the operation duration can be increased to a long time and the convenience can be improved.

  In the present invention, the timer includes a timer that counts the remaining time in the normal operation mode, and a timer that counts the remaining time in the BLD operation mode that warns of a low voltage state. When the remaining time of the timer that counts the remaining time becomes 0 hour, and when the portable amount detected by the portable amount detection unit is less than a predetermined value, the device is operated in the BLD operation mode, The operation stop unit controls the apparatus to be in an operation stop state when the remaining time of a timer for measuring the remaining time in the BLD operation mode becomes 0 hour, and the operation resumption unit is charged in the BLD operation mode. When the state is detected, it is preferable to operate the operation duration adjusting unit.

If the BLD operation mode is provided, when the remaining operation duration becomes 0 hour, the operation is not stopped suddenly, but the user is warned that the voltage of the power storage means has decreased. Then you can stop driving. For this reason, the user can also prevent the operation stop by performing the power generation operation by the power generation means, and the convenience can be improved.
Further, when the state of charge is detected in the BLD operation mode, the operation duration adjustment unit is operated, so that the user confirms that the BLD operation mode has been entered and performs a power generation operation. The convenience can be improved by moving to.

  In the present invention, the device is time display means for displaying time, and the operation control means operates the timer even when the time display state for correcting the time displayed by the time display means is entered. It is preferable to continue.

  According to the present invention, even when the electronic device is left in the time correction state, the timer continues to operate, and the operation is stopped when the duration becomes 0, so that the voltage of the power storage means is significantly reduced. Can be prevented.

The present invention includes a power generation unit, a power storage unit that stores electrical energy generated by the power generation unit, a device that is operated with the electrical energy stored in the power storage unit, and a power generator to the power storage unit. A charge detection means for detecting a charge state, and an operation control means for controlling the operation state of the device, and a method for controlling a portable electronic device with a power generation function to be carried and used, the operation control means comprising: An operation stop process for setting the operation duration to a plurality of time lengths, including a timer for measuring the remaining time, and controlling the device to an operation stop state when the remaining time of the timer becomes 0 When the state of charge is detected by the charge detection means, the operation of the device is resumed, and when the amount of carry is detected and the amount of carry becomes a predetermined value, the operation duration is set in the timer. And operating duration adjustment process that is characterized by a run.
According to the present invention, the same effects as the portable electronic device with the power generation function can be obtained.

Manual winding power transmission means 47.
Note that the power generation means may be provided with only the power generation device 40 and the automatic power generation transmission means 46 without including the manual power generation transmission means 47.

  The power generator 40 is a general AC generator including a stator 42 in which a rotor 41 is rotatably arranged and a coil block 44 around which a coil 43 is wound.

The automatic winding power transmission means 46 includes a rotary spindle 461 that rotates integrally with the rotary spindle 2 and a switching wheel 463 that transmits the rotation of the rotary spindle 461. The switching wheel 463 meshes with the rotor 41 and when the rotating weight 2 rotates, the rotational force is transmitted to the rotor 41 via the rotating wheel 461 and the switching wheel 463, and power generation is performed in the power generation device 40.
Note that the switching wheel 463 is configured to include interference avoiding means such as a ratchet wheel or a sliding structure (not shown), and transmits force during manual winding power generation and force transmission from the movement of the rotating weight during automatic winding power generation. Are configured not to interfere with each other.

[Rectifying means]
The rectifying means 5 rectifies the alternating current output from the power generator 40, and a known rectifier circuit such as a full-wave rectifier circuit or a half-wave rectifier circuit can be used.

[Charging detection means]
The charge detection means 6 detects whether or not the current generated by the power generation means 4 is charged in the secondary battery 7. For this reason, the charge detection means 6 may be a current detection circuit that detects the magnitude of the current rectified by the rectification means 5 or a voltage detection circuit that detects a voltage generated by the rectification means 5 during charging.
Therefore, conventionally known various current detection circuits and voltage detection circuits can be used as the charge detection means 6. For example, the current detection circuit includes a resistor arranged between the rectifying means 5 and the secondary battery 7, a peak detection circuit for measuring a current flowing through the resistor and detecting a peak value of the generated current, and a peak detection circuit. A current detection circuit provided with a comparison circuit that compares the detected value with a threshold value can be used.

The output of the power generation means 4 is rectified by the rectification means 5 and charged to the secondary battery 7 via the charge detection means 6. The power storage means is not limited to the secondary battery 7, and a capacitor may be used.

[Secondary battery voltage detection means]
The voltage of the secondary battery 7 is detected by battery voltage detection means 71. The battery voltage detection means 71 is configured by a general voltage detection means that detects the voltage of the secondary battery 7 at a predetermined sampling timing (for example, every 2 seconds).

[Timekeeping control means and time display means]
Since the time measuring control means and the time display means for displaying the normal time have the configuration of a conventional general analog quartz timepiece, detailed description thereof is omitted.
That is, the oscillating means 12 includes a crystal resonator and an oscillating circuit, and outputs a signal having a predetermined frequency. The frequency dividing means 13 divides the signal from the oscillating means 12 and outputs a reference signal of 1 Hz, for example.

The time display control unit 14 outputs a drive signal to the time display motor driving unit 15 based on the reference signal of the frequency dividing unit 13. Normally, each time a 1 Hz reference signal is input from the oscillating means 12, a drive signal is output. The time display motor drive means 15 inputs the time display motor 16 to the motor coil of the time display motor 16 based on the drive signal, and the time display motor 16 steps the time display pointer 20.
In the present embodiment, a clock circuit is constituted by the oscillation means 12, the frequency dividing means 13, the time display control means 14, and the like.

[Operation stop part]
As will be described later, the operation stop unit 141 of the time display control unit 14 shifts to a sleep mode in which the hand movement of the time display hand 20 is stopped when the duration timed by the timer 143 reaches 0 hours. It is configured. In the present embodiment, a BLD counter 143E is also provided as the timer 143, and the processing in the BLD display mode is performed after the duration of normal hand movement reaches 0 hour. For this reason, the operation stop unit 141 stops the hand movement when the BLD counter 143E that operates in the BLD display mode reaches 0 hour.

In the sleep mode, (A) the time display motor driving means 15 is stopped and the movement of the hands 20 is stopped, but the oscillation means 12 and the frequency dividing means 13 are operated to keep the current time. There are a hand movement stop mode and an IC operation stop mode (IC operation stop function) in which the IC operation is also stopped and the current time is stopped in order to reduce power consumption from (B). In the sleep mode of this embodiment, (B) IC operation stop mode is set.
The electronic timepiece 1 may be provided with one of these stop modes, or may be provided with both stop modes and the user may select the stop mode. Furthermore, both stop modes are provided, and the mode is shifted to the hand movement stop mode immediately after shifting to the sleep mode, and the mode is automatically shifted to the IC operation stop mode when the hand movement stop mode is continued for a predetermined period (for example, one week). You may control.

[Operation restart part]
The operation resuming unit 142 of the time display control unit 14 cancels the IC operation stop function when charging (power generation of the power generation unit 4) is detected in the charge detection unit 6 when operation is stopped (sleep mode). Resume operation.

When the sleep mode is the IC operation stop mode, since the current time is unknown, the operation resuming unit 142 starts the operation of the pointer 20 that has been stopped as it is. In this case, since the current time and the time indicated by the hands 20 are often shifted, it is necessary for the user to adjust the time by operating the crown 3 or the button 8. While the time adjustment operation is performed with the crown 3 or the like, the operation of the timer 143 is continued and the remaining time of the duration is continuously counted.
When the sleep mode is the hand movement stop mode, since the current time is measured, the operation resuming unit 142 operates the time display motor driving means 15 to automatically correct the pointer 20 to the current time.

[timer]
The timer 143 is a counter that counts the operation duration. In this embodiment, the timer 143 counts the remaining time in the normal operation mode and the remaining time in the warning display operation mode (BLD operation mode) that warns of a voltage drop. There are counters for counting and driving duration adjustment period (for rank-up adjustment period).

[Counter for normal operation mode]
As counters for counting the remaining time in the normal operation mode, a plurality of, specifically, four counters 143A to 143D are provided. These counters 143A to 143D are down counters that sequentially subtract and count the set initial values.
The first counter (first timer) 143A counts down one day (24 hours). The second counter (second timer) 143B counts down the period of 6 days, the third counter (third timer) 143C counts down the period of 23 days, and the fourth counter (fourth timer) 143D Count down for a period of 150 days.
Therefore, the first to fourth counters 143A to 143D can count the maximum duration of 1 day + 6 days + 23 days + 150 days = 180 days.

[BLD operation mode counter]
A BLD counter 143E is provided as a counter for counting the remaining time for the BLD operation mode. The BLD counter (BLD timer) 143E counts down 24 hours. The BLD counter 143E sets a period for performing BLD display with the pointer 20. The BLD display is a warning display called battery low display, battery life indicator, etc. For example, the second hand is moved every 2 seconds for 2 seconds. The minute hand movement is used to perform a warning operation that is different from the normal hand movement. This notifies the user that the battery voltage is decreasing.
If the operation is stopped without performing the BLD display, the timer 143 may not be provided with the BLD counter 143E.

[Counter for adjustment period]
As counters for counting the remaining time of the adjustment period, a first adjustment period counter 147A and a second adjustment period counter 147B are provided. The first adjustment period counter 147A is a timer that counts one day (24 hours) by up-counting. The second adjustment period counter 147B is a timer that counts seven days as an up-count.

[Duration display control unit]
The duration display control unit 145 includes (A) an indicator display function of an operation duration using the second hand 23, and (B) a function of controlling the operation of the timer 143.
That is, when the duration display operation is performed by the button 8, the duration display control unit 145 confirms the voltage of the secondary battery 7 detected by the battery voltage detection unit 71. Then, the duration display control unit 145 determines which range of a plurality of preset voltage ranges the voltage of the secondary battery 7 corresponds to.
Here, in this embodiment, as shown in FIG. 5, four continuous voltage ranges Vr1 to Vr4 are set. Specific voltage values in each voltage range are set as appropriate depending on the type of the electronic timepiece 1, and are exemplified as follows.
In the first voltage range Vr1, the voltage of the secondary battery 7 is VBLD (for example, 1.2V) or more and less than Vind1 (for example, 1.3V).
In the second voltage range Vr2, the voltage of the secondary battery 7 is not less than Vind1 (eg, 1.3V) and less than Vind2 (eg, 1.4V).
In the third voltage range, the voltage of the secondary battery 7 is not less than Vind2 (for example, 1.4 V) and less than Vind3 (for example, 1.5 V).
In the fourth voltage range, the voltage of the secondary battery 7 is equal to or higher than Vind3 (for example, 1.5 V).
In addition, the range where the voltage of the secondary battery 7 is less than VBLD (for example, 1.2V) and Von (for example, 1.1V) or more is set to the BLD voltage range Vr0 for performing BLD display.

  The duration display control unit 145 determines which voltage range the voltage of the secondary battery 7 corresponds to, and as shown in Table 1 below, the indicator display processing set for each voltage range, and the timer 143 Perform duration setting processing.

The indicator display of 5 seconds is a method of moving the second hand 23 to 5 seconds. That is, the duration display control unit 145 controls the time display motor drive unit 15 to fast-forward the second hand 23 by 5 seconds, and then stops until 5 seconds after the fast-forward start time.
Similarly, the indicator display of 10 seconds is a method of moving the hand in which the second hand 23 is fast-forwarded by 10 seconds and then stops until 10 seconds after the start of fast-forwarding. The indicator display of 20 seconds means that the second hand 23 is moved to 20 seconds. This is a method of moving the hand that stops 20 seconds after the fast-forward start time after fast-forwarding by the minute. The indicator display 30 seconds means that the second hand 23 is fast-forwarded by 30 seconds and then stops 30 seconds after the fast-forward start time. It is a hand movement method.
In addition, as described above, the BLD display is a hand movement method in which, for example, the second hand 23 is fast-forwarded by 2 seconds every 2 seconds.

  Further, the duration display control unit 145 operates a counter corresponding to the voltage range including the detected voltage of the secondary battery 7 and sets the operation duration in the timer 143. The timer (counter) in which the duration display control unit 145 operates and the set duration are as described in Table 1 above.

[Timer update section]
The timer update unit 146 updates the remaining time of the timer 143 if a predetermined condition is met when the charge detection unit 6 detects a charge state while the timer 143 (first to fourth counters 143A to 143D) is operating. To do.
Specifically, the timer update unit 146, when the operation duration according to the detection voltage Vs of the secondary battery 7 detected by the battery voltage detection means 71 is longer than the remaining time of the timer 143 in operation, The remaining time of the timer 143 is updated to the operation duration according to the detected voltage.
On the other hand, when the operation duration time corresponding to the detected voltage is equal to or less than the remaining time of the operating timer 143, the timer update unit 146 operates the timer 143 without being updated. The operation duration according to the detected voltage is the same as that shown in Table 1 set by the duration display control unit 145.

[Portable volume detection unit]
The carry amount detection unit 147 detects the carry amount of the electronic timepiece 1 when the operation resumption unit 142 resumes the operation. The carrying amount of the electronic timepiece 1 is a parameter corresponding to the length of time the electronic timepiece 1 is carried. In the present embodiment, as will be described later, the portable amount is detected based on the frequency of charge detection by the charge detection means 6.

[Driving time adjustment section]
The driving duration adjusting unit 148 adjusts the driving duration when the carrying amount detected by the carrying amount detecting unit 147 reaches a predetermined value when the driving is resumed by the driving resuming unit 142. In the present embodiment, as will be described later, the operation duration is adjusted based on the carrying amount and the detection voltage Vs.

[Description of operation of electronic timepiece 1]
Next, the operation of the electronic timepiece 1 having such a configuration will be described.

[Operation stop mode]
First, an operation stop mode (step 1, hereinafter, step is abbreviated as “S”), which is an operation when the time display means (device) is in the IC operation stop state, will be described based on the flowchart of FIG.
The operation stop mode (sleep mode) S1 is executed, as will be described later, when the operation duration of normal operation is 0 hour and the BLD display counter 143E is 0 hour. This is a case where the voltage of the secondary battery 7 falls below the system stop voltage Von. It should be noted that the BLD display counter 143E becomes 0 hours when the normal operation mode shifts to the BLD display mode, and when the operation is resumed, the carrying amount does not reach the predetermined value and the adjustment period counters 147A and 147B are 0. This is a case where the time shifts to the BLD operation mode due to time and there is no charge detection during the BLD operation mode.

When the operation of the time display means is stopped and the operation stop mode S1 is executed, the operation of the IC, that is, the time display control means 14 is stopped, and only the charge detection means 6 is operating.
For this reason, the charge detection means 6 is checking whether the charge state was detected (S2).
Until the charge state is detected in S2, the charge detection means 6 continues to check the charge detection.

On the other hand, when the state of charge is detected in S2, the operation resuming unit 142 operates by inputting a detection signal from the charge detection unit 6 to the time display control unit 14, and the IC operation stop function is canceled (S3). .
Then, the operation resuming unit 142 detects the voltage (detection voltage) Vs of the secondary battery 7 at the time of charge detection by the battery voltage detection means 71 (S4). When a memory such as a RAM is provided, the detected voltage value may be stored in a memory such as a RAM.

Next, the operation resuming unit 142 determines whether the detected voltage Vs is less than the system stop voltage Von (S5). If it is determined Yes in S5, the voltage of the secondary battery 7 is low and normal operation cannot be resumed, so the operation stop unit 141 stops the IC operation (S6) and restarts the operation stop mode S1.
When it is determined No in S5, that is, when the detected voltage Vs is equal to or higher than the system stop voltage Von, the operation resuming unit 142 determines whether or not the detected voltage Vs is within the BLD voltage range (S7). Therefore, if the detection voltage Vs is not less than the system stop voltage Von and less than VBLD, it is determined Yes in S7.

When it determines with Yes by S7, the driving | operation restarting part 142 performs BLD driving mode mentioned later (S30).
When it is determined No in S7, that is, when the detected voltage Vs is equal to or higher than VBLD, the operation resuming unit 142 determines whether or not the detected voltage Vs is in the first voltage range (S8).

[Start-up process in the first voltage range]
When it determines with Yes by S8, the driving | operation restarting part 142 performs the starting process in a 1st voltage range. That is, the operation resuming unit 142 sets an initial value in the first counter 143A and starts counting (S9). Further, the operation resuming unit 142 executes a normal operation mode S20 described later.
Here, the first counter 143A is a down counter that counts one day (24 hours). For this reason, the first counter 143A is set with an initial value for counting the operation duration of the day as a counter value, and a timer 143 for measuring the operation duration of the day is configured. For example, when the first counter 143A counts down every second, the initial value is 60 seconds × 60 minutes × 24 hours = 86400. Accordingly, the operation resuming unit 142 sets the initial value 86400 in the first counter 143A, and decreases the counter value by “1” every second using the 1 Hz reference signal input from the frequency dividing means 13 or the like. .

  Here, VBLD which is the lower limit value of the first voltage range is the time when the time display motor 16 is in the state where the power generation means 4 is not generating power when the voltage of the secondary battery 7 is VBLD. It is set so that the voltage of the secondary battery 7 does not become less than the system stop voltage Von at the time when the operation is performed for one day with only the electric power.

  When it is determined No in S8, that is, when the detected voltage Vs is greater than or equal to Vind1, the operation resuming unit 142 performs normal hand movement display (S10), and further operates the operation duration adjusting unit 148 to adjust the operation duration. Processing (rank-up adjustment processing) is executed (S70).

[Driving time adjustment process]
The operation duration adjustment process S70 will be described with reference to the flowchart of FIG.
The operation duration adjustment processing is not to simply set the operation duration based on the voltage value of the detection voltage Vs at the time of restarting the operation, but to check the carrying amount based on the carrying state of the electronic timepiece 1. When the number is small, the duration is set short, and the duration is adjusted longer (rank-up adjustment) as the amount of mobile phone increases.
For this reason, when it is determined No in S8, that is, when the detected voltage Vs is greater than or equal to Vind1, the operation duration adjustment process S70 is executed, and when the detected voltage Vs is in the first voltage range, it is not executed. This is because, if the detection voltage Vs is in the first voltage range, the set operation duration is also as short as the initial value of the first counter 143A, that is, one day (24 hours). When such a short driving duration is set, the electronic timepiece 1 is temporarily moved to detect charging, and then, even if it is not carried around, one day has passed and the normal operation mode has passed. Since the operation is stopped when one day has passed since the transition from S20 to the BLD operation mode S30 (that is, when a total of two days has elapsed), the operation of the secondary battery 7 continues to be consumed wastefully. This is because there is nothing.
However, when it is determined No in S7 and the detected voltage Vs is equal to or higher than VBLD, the operation duration adjustment process S70 may be executed.

The operation duration adjustment unit 148 starts counting by the second adjustment period counter 147B (7-day timer) (S71). Furthermore, the carry amount C2, which is the number of carry amounts detected for one day, is initialized to “0” (S72).
The driving duration adjustment unit 148 operates the portable amount detection unit 147 to execute a daily portable amount detection process (S90).

[Daily carrying amount detection process]
As shown in FIG. 8, the portable amount detection unit 147 starts counting by the first adjustment period counter 147A (daily timer) (S91). Also, a variable C1 indicating the number of time zones (portability status detection time zones) in which the mobile phone state is detected is initialized to “0” (S92).
In the present embodiment, the day is divided into eight time zones with the start point of the daily carrying amount detection process S90 as a base point. For this reason, the time length of each time zone is 3 hours.
Therefore, for example, when 7:10 is the base point, the first time range: 7: 10-10: 10, the second time range: 10: 10-13: 10, the third time range: 13: 10-16: 10, 4th time range: 16: 10-19: 10, 5th time range: 19: 10-22: 10, 6th time range: 22: 10- The next day is 1:10, 7th time zone: 1: 10-4: 10, and 8th time zone: 4: 10-7: 10.

  Note that the number of divisions in the time zone of the day is not limited to eight. For example, one day may be divided into 12 time zones, and the length of each time zone may be 2 hours. Alternatively, one day may be divided into 24 time zones, and the length of each time zone may be 1 hour.

And the portable amount detection part 147 determines whether the charge state was detected by the charge detection means 6 twice or more in one time range (S93). For example, if the state of charge is detected twice or more in the first time range, it is determined Yes in S93.
When it determines with Yes by S93, the portable amount detection part 147 adds "1" to C1 (S94). Therefore, when two or more times of charging are detected in the first time range and it is determined Yes in S93, C1 is updated to “1”.
Note that the portable amount detection unit 147 does not perform charge detection for a predetermined time (for example, 6 to 8 minutes) after the first charge detection in each time zone. This is because if two consecutive charging detections are permitted, the electronic timepiece 1 is not carried, but a single operation such as changing the place of the electronic timepiece 1 is determined to be in a portable state. This is to prevent misjudgment by providing an interval of several minutes.

The portable amount detection unit 147 determines whether one day has been counted by the first adjustment period counter 147A that is a one-day timer, that is, whether one day has elapsed since the start of the daily portable amount detection process S90. (S95).
When it determines with No by S95, the portable amount detection part 147 repeats the process of S93-S95 again. Accordingly, when it is detected that there has been charging twice or more in any of the second to eighth time zones, it is determined Yes in S93, and “1” is added to the variable C1 (S94).

If it is determined in S95 that one day has elapsed (Yes in S95), the portable amount detection unit 147 determines whether the C1 is “3” or more (S96).
If it determines with Yes by S96, the portable amount detection part 147 will add "1" to the said portable amount C2 (S97). In the case of the first daily portable amount detection process S90 shown in FIG. 7, since C2 is the initial value “0”, the portable amount detection unit 147 updates C2 to “1” and performs the daily portable amount detection process S90. Terminate the process. After the process of S97, the portable amount detection unit 147 resets and restarts the second adjustment period counter 147B, which is a 7-day timer (S98).

In the present embodiment, the threshold value “3” in the determination process in S96 is set in consideration of the minimum time required to be carried from the relationship between the power generation amount of the electronic timepiece 1 and the power consumption. Yes. That is, in the power generation means 4 of this embodiment, a portable time of about 4 to 10 hours is required to increase the voltage of the secondary battery 7, but in this embodiment, the time is set to 6 hours. If it has been carried for a time longer than 6 hours, it is determined that the amount of carry has reached one day. Here, in this embodiment, since the length of each time zone is 3 hours, when carrying state is detected in three time zones, it is determined that the carrying amount for one day has been reached. Therefore, in S96, it is determined whether C1 is “3” or more.
Therefore, when the time zone is divided into 12, the time length of each time zone is 2 hours. Therefore, when carrying status is detected in four time zones (total 8 hours), the carrying amount for one day What is necessary is just to determine with having reached. Similarly, when the time zone is divided into 24, the time length of each time zone is 1 hour, so when carrying status is detected in 7 time zones (7 hours in total) It may be determined that the amount has been reached.

Also, if you set the time zone to 3 divisions (8 hours x 3 time zones) etc., you can determine that you have reached the carrying amount for one day just by detecting that there was a charge in one time zone, In this case, since the count number is as small as one, there is an advantage that the circuit scale can be reduced. However, if it is determined only in one time zone, even if the electronic timepiece 1 is not carried around, such as when the time confirmation operation is temporarily performed within that time zone, the power generation is temporarily generated and the state of charge is detected. There is a risk of misjudging that it was carried.
On the other hand, if the threshold of S96 is set to “6” or the like and the count number of the determination condition is increased too much, it becomes difficult to clear the condition. There is a risk of it.
In addition, for example, when the time zone is too long, for example, 24 hours, when the electronic timepiece 1 is activated to some extent, it is erroneously determined that it is not actually carried but is carried. there's a possibility that. Therefore, as in the above-described embodiment, it is necessary to determine the carrying state in a plurality of time zones within one day.

On the other hand, when it is determined No in S96, that is, when the time range in which the charge detection is performed twice or more is 2 or less, the portable amount detection unit 147 is for the second adjustment period which is a 7-day timer. The counter 147B is counted up for one day (S99). That is, the 7-day timer is reset when it is determined Yes in S96 and the carrying amount for one day is detected, and is determined as No in S96 and is counted for one day when the carrying amount for one day cannot be detected. Up. For this reason, the 7-day timer (the second adjustment period counter 147B) counts the number of days when the state where the carrying amount for one day cannot be detected continues.
And the portable amount detection part 147 complete | finishes the process of daily portable amount detection process S90, without updating C2.

  Returning to FIG. 7, the driving duration adjustment unit 148 determines whether or not C2 is larger than “0” when the daily portable amount detection process S90 ends (S73). If the daily carrying amount detection process S90 cannot detect the carrying amount for one day and it is determined No in S73, the user is likely not using the electronic timepiece 1. For this reason, the operation duration adjustment unit 148 executes a BLD operation mode S30 described later. In the BLD operation mode S30, the BLD display process is performed for 24 hours, and the operation is stopped if no charge is detected during that time. For this reason, if the user uses the electronic timepiece 1, the user is aware of the warning display and performs the charging process, so that the normal operation can be resumed. On the other hand, if the user is not using the electronic timepiece 1, the operation can be stopped after a 24-hour warning display.

[2-day mobile detection]
If it is determined Yes in S73, the driving duration adjustment unit 148 performs the daily carrying amount detection process S90 again following the previous day. Accordingly, even on the second day, if two or more charges are detected in any three time zones of the first to eighth time zones, “1” is added to C2, and C2 becomes “2”.
Therefore, the driving duration adjustment unit 148 determines whether C2 is “2” or more when the daily portable amount detection processing S90 on the second day is completed (S74).
If it is determined No in S74, the carrying state of the electronic timepiece 1 can be detected on the first day, but the charging state cannot be detected on the second day and the carrying state cannot be detected. 1 mobile phone is expected to stop. For this reason, the operation duration adjustment unit 148 executes the BLD operation mode S30 as in the case where it is determined No in S73.
On the other hand, when it determines with Yes by S74, the driving | running | working duration adjustment part 148 determines whether the detection voltage Vs at that time is more than Vind2 (S75).

[Startup process in the second voltage range]
When it is determined No in S75, since the detected voltage Vs is not in the high voltage region higher than the third voltage region, the operation resuming unit 142 sets initial values in the first counter 143A and the second counter 143B, and counts them. Start (S76). In the second counter 143B, an initial value corresponding to 6th is set as a counter value. Accordingly, the first counter 143A and the second counter 143B constitute a timer 143 that measures the operation duration of 7 days.
When the timer 143 is constituted by a plurality of counters, the down-counting is started from a counter having a long counting period. For this reason, in the second voltage range using the first counter 143A and the second counter 143B, the second counter 143B first performs a down-count, and when the counter value of the second counter 143B becomes 0 after 6 days, Count down one counter 143A and count one day. That is, a period of 6 days + 1 day = 7 days is counted by the first counter 143A and the second counter 143B.

  Here, Vind1 which is the lower limit value of the second voltage range is the time when the time display motor 16 is in the state where the power generation means 4 is not generating power when the voltage of the secondary battery 7 is Vind1. It is set so that the voltage of the secondary battery 7 does not become less than VBLD when it is operated for 7 days with only the electric power. In this embodiment, Vind1 is set to a voltage that can ensure a duration of about 20 days with a margin.

[Cellular detection for 7 days]
When it is determined Yes in S75, the driving duration adjustment unit 148 can detect the carrying state for seven days to determine whether the driving duration may be set to a long period of 30 days or 180 days. Determine whether.
That is, the driving duration adjustment unit 148 executes the daily carrying amount detection process S90 again, and the driving duration adjustment unit 148 determines whether C2 is “7” or more (S77).
The second adjustment period counter 147B starts counting at the start of the operation duration adjustment process S70, and has already performed the daily portable amount detection process S90 twice.
Therefore, the portable amount C2 is “2” at the time point determined as Yes in S75. For this reason, even if the carrying amount for one day is detected again in S90, C2 is only “3”. Therefore, it is determined No in the first determination process of S77.

When it is determined No in S77, the operation duration adjustment unit 148 determines whether 7 days have been counted by the 7-day timer (second adjustment period counter 147B) (S78). As described above, the 7-day timer counts the number of days for which the carrying amount for one day could not be detected continuously. For this reason, if the carrying amount for one day is detected in the daily carrying amount detection processing S90 after the determination of Yes in S75 (Yes in S96), the 7-day timer is reset and restarted. Therefore, the count value is “0”. Further, when the carrying amount for one day is not detected (No in S96), the count value is “one day” because it is the first day that cannot be detected.
Therefore, since it is determined No in S78, the daily carrying amount detection process S90 is executed again.

  If the daily carrying amount is not detected in the daily carrying amount detection process S90, the value of C2 is not updated, and the 7-day timer counts up for one day. Therefore, the processing of S90, S77, and S78 is repeated until it is determined Yes in S78. If the carrying amount for one day cannot be detected for seven consecutive days, seven days are counted by the seven-day timer and the process ends. For this reason, it determines with Yes by S78. In this case, in order to alert the user that the mobile phone is not being carried, the driving duration adjusting unit 148 executes the BLD driving mode S30.

On the other hand, if it is determined Yes in S77, that is, before the state in which the carrying amount for one day cannot be detected for seven consecutive days occurs, the date on which the carrying amount for one day can be detected is accumulated for seven days. When it becomes, the operation duration adjustment unit 148 determines whether or not the detected voltage Vs is equal to or greater than Vind3 (S79).
In other words, C2 = 2 is detected by carrying for two days, and after determining Yes in S75, even if there is a day when the carrying amount for one day cannot be detected, the day when the carrying amount for one day can be detected. Is accumulated for 5 days, and when C2 = 2 + 5 = 7, Yes is determined in S77.

[Start-up process in the third voltage range]
When it is determined No in S79, the operation resuming unit 142 sets the first counter 143A, the second counter 143B, and the third counter 143C to initial values, and starts counting (S80). In the third counter 143C, an initial value corresponding to the 23rd is set as a counter value. Accordingly, the first counter 143A, the second counter 143B, and the third counter 143C constitute a timer 143 that measures the operation duration of 30 days.
In the third voltage range, the third counter 143C first counts down. When the counter value of the third counter 143C becomes 0 after 23 days, the second counter 143B performs down-counting. Next, when the counter value of the second counter 143B becomes 0 after 6 days, the first counter 143A performs down-counting. That is, a period of 23 days + 6 days + 1 day = 30 days (one month) is counted by the first counter 143A, the second counter 143B, and the third counter 143C.

  Here, Vind2, which is the lower limit value of the third voltage range, is the time when the time display motor 16 is in a state where the power generation means 4 is not generating power when the voltage of the secondary battery 7 is Vind2. It is set so that the voltage of the secondary battery 7 does not become less than VBLD at the time when the battery is operated for 30 days with only the electric power. In the present embodiment, Vind2 is set to a voltage that can secure a duration of about 80 days with a margin.

[Start-up processing in the fourth voltage range]
When it is determined Yes in S79, the operation resuming unit 142 sets the first counter 143A, the second counter 143B, the third counter 143C, and the fourth counter 143D to initial values, and starts counting (S81). In the fourth counter 143D, an initial value corresponding to 150 days is set as a counter value. Accordingly, the first counter 143A, the second counter 143B, the third counter 143C, and the fourth counter 143D constitute a timer 143 that measures the operation duration of 180 days.
Then, in the fourth voltage range, the fourth counter 143D first counts down, and when 150 days have passed and the counter value of the fourth counter 143D becomes 0, the third counter 143C performs the down count. Next, when the counter value of the third counter 143C becomes 0 after 23 days, the second counter 143B performs down-counting. Next, when the counter value of the second counter 143B becomes 0 after 6 days, the first counter 143A performs down-counting. That is, a period of 150 days + 23 days + 6 days + 1 day = 180 days (6 months) is counted by the first counter 143A, the second counter 143B, the third counter 143C, and the fourth counter 143D.

  Here, Vind3 which is the lower limit value of the fourth voltage range is the time when the time display motor 16 is in the state where the power generation means 4 is not generating power when the voltage of the secondary battery 7 is Vind3. It is set so that the voltage of the secondary battery 7 does not become less than VBLD when it is operated for 180 days with only the electric power. In this embodiment, Vind3 is set to a voltage that can secure a duration of about 200 days with a margin.

  The operation resuming unit 142 sets the operation duration based on the carrying amount and the detected voltage Vs by the operation duration adjustment unit 148 through the processes of S76 to S81, and when the operation duration adjustment process (rank-up process) is completed, The process proceeds to a normal operation mode S20 described later.

[Normal operation mode]
Next, the process in the normal operation mode S20 will be described with reference to FIG.
In the normal operation mode S20, the time display control means 14 controls the time display motor drive means 15 to perform normal hand movement processing (S21). This normal hand movement process is continued until the operation is stopped by the operation stop unit 141. However, in the duration display process S50 and the BLD operation mode S30, which will be described later, pointer drive control different from normal hand movement is performed.

  The time display control means 14 determines whether or not the duration of normal operation has reached 0 hour (S22). Specifically, since the duration set in each voltage range ends when the first counter 143A finally becomes 0, it is determined whether or not the first counter 143A has become 0. And when it determines with Yes by S22, the time display control means 14 performs the BLD operation mode mentioned later (S30).

On the other hand, when it determines with No by S22, the time display control means 14 checks the output of the charge detection means 6, and determines whether the charge state was detected (S23). When it is determined Yes in S23, the time display control unit 14 executes a timer update process S40 described later by the timer update unit 146.
On the other hand, when it is determined No in S23, that is, when charge detection is not performed, the timer update process S40 is not executed.

After the timer update process S40 is executed or when it is determined No in the charge state detection process S23, the time display control unit 14 determines whether or not the duration display operation has been performed by operating the button 8 ( S24). When it determines with Yes in S24, the duration display control part 145 performs the duration display process S50 mentioned later, and returns to a normal hand movement process (S21).
On the other hand, when it is determined No in S24, the time display control unit 14 returns to the normal hand movement process (S21) without executing the duration display process.
Therefore, the normal operation mode S20 is continuously executed until the normal operation duration becomes 0 hour.

[Timer update processing]
Next, the timer update process S40 will be described with reference to FIG.
When the timer update process S40 is executed, the timer update unit 146 acquires the voltage Vs of the secondary battery 7 detected by the battery voltage detection means 71 (S41). Next, the timer update unit 146 determines whether or not the detected voltage Vs is less than the system stop voltage Von (S42). If it determines with Yes in S42, the driving | operation stop part 141 will stop a hand movement (S43), and the above-mentioned driving | running | working stop mode S1 which is the operation | movement process at the time of a driving | operation stop will be performed.

On the other hand, when it determines with No by S42, the timer update part 146 determines whether the detection voltage Vs is less than VBLD (S44). If it is determined Yes in S44, the time display control means 14 executes the BLD operation mode S30.
Since the timer update process S40 is executed when charging is detected in the normal operation mode, there is almost no possibility that the detection voltage Vs becomes less than the system stop voltage Von or less than VBLD. Then, the process of S42-S44 is set as an error countermeasure when a voltage falls.

Next, the timer update unit 146 confirms whether there is an operating timer 143 (S45). Here, in the normal operation mode, one or more counters set in S9, S76, S80, and S81 of the operation duration adjustment process S70 are usually set when the operation is resumed in the operation stop mode S1 shown in FIG. Since the configured timer 143 is operating, it is determined Yes in S45.
In that case, the timer update unit 146 includes the first to the first durations including the operation duration, that is, the detection voltage Vs, set in accordance with the detection voltage Vs detected in S41. It is determined whether it is longer than the initial value of the timer 143 set by the fourth voltage range (S46).
In other words, the timer update unit 146 determines Yes in S46 if there is a counter corresponding to a voltage range in which the detected voltage Vs is higher than the corresponding voltage range among the counters constituting the operating timer.

For example, when the detection voltage Vs is in the first voltage range, the corresponding operation duration is one day. Therefore, if the remaining duration of the operating timer 143 is longer than one day, it is determined Yes in S46, and the timer update unit 146 does not reset the timer 143, but does not reset the timer 143 that is currently operating. Is used as it is. In addition, when the remaining duration of the operating timer is longer than one day, the initial value is set in the second counter 143B, the initial value is set in the second counter 143B, or the third counter 143C or This is a case where the downcounting is performed by the fourth counter 143D. Therefore, by checking whether the second counter 143B is 0 hour, it can be determined whether the remaining duration of the operating timer 143 is longer than one day.
Similarly, when the detected voltage Vs is in the second voltage range and the remaining duration of the operating timer 143 is longer than 7 days, it is determined Yes in S46, and the timer update unit 146 sets the timer 143. The counter that is currently in operation is used as it is without being repaired. In this case as well, the determination can be made by confirming whether the third counter 143C has reached 0 hours.
Also, when the detected voltage Vs is in the third voltage range and the remaining duration of the operating timer 143 is longer than 30 days, it is determined Yes in S46, and the timer update unit 146 resets the timer 143. Do not do anything, use the counter that is currently in operation. Also in this case, the determination can be made by confirming whether the fourth counter 143D has reached 0 hours.

  That is, the timer update unit 146 determines that the current detection voltage Vs is lower than the detection voltage Vs when the currently active timer 143 is set and falls within a lower voltage range in S46. In this case, the operating timer 143 is used as it is.

  On the other hand, when the operation duration corresponding to the current detection voltage Vs is longer than the remaining duration of the currently operating timer 143, the timer update unit 146 determines No in S46. For example, after the initial duration of 180 days is set, if the operation is performed for 175 days without charge detection, the remaining duration is 5 days. At this time, the user may vibrate the electronic timepiece 1 to extend the duration, or operate the crown 3 to generate power with the power generation means 4, and charge the secondary battery 7 to increase the voltage. . When the voltage of the secondary battery 7 is increased to the second, third, and fourth voltage ranges in this way, the duration corresponding to the detected voltage is 7 days, 30 days, and 180 days, and the current remaining duration is 5 days. Also gets longer. In this case, it is determined No in S46.

When it is determined No in S45 and when it is determined No in S46, the timer update unit 146 sets the initial value of the counter (timer 143) corresponding to the detected voltage Vs and starts counting by the counter. (S47).
For example, if the remaining duration is 5 days and the detected voltage Vs is in the third voltage range, No is determined in S46. In this case, the timer update unit 146 sets the timer 143 (the timer 143 including the first counter 143A, the second counter 143B, and the third counter 143C) that is set corresponding to the third voltage range including the detection voltage Vs. Set the initial value and start counting.

  When the process of S47 is performed and when it is determined Yes in S46, the time display control unit 14 ends the timer update process S40 by the timer update unit 146, and enters the normal operation mode S20 shown in FIG. Return.

[Duration display processing S50]
Next, the process of the duration display process S50 will be described with reference to FIG.
When the duration display process S50 is executed, the duration display control unit 145 acquires the voltage Vs of the secondary battery 7 detected by the battery voltage detection means 71 (S51). Next, the duration display control unit 145 determines whether the detected voltage Vs falls within the first to fourth voltage ranges and the BLD voltage range (S52 to S56).

[Duration display processing in the first voltage range]
When the detection voltage Vs is included in the first voltage range (Yes in S52), the duration display control unit 145 sets an initial value to the timer 143 configured by the first counter 143A and starts counting (S57). Further, the time display motor driving means 15 is controlled to execute the above-described 5-second display process of the indicator (S58).

[Duration display processing in the second voltage range]
When the detected voltage Vs is included in the second voltage range (Yes in S53), the duration display control unit 145 sets an initial value to the timer 143 including the first counter 143A and the second counter 143B, and starts counting. (S59). Further, the time display motor driving means 15 is controlled to execute the above-described indicator 10-second display process (S60).

[Duration display processing in the third voltage range]
When the detected voltage Vs is included in the third voltage range (Yes in S54), the duration display control unit 145 sets an initial value to the timer 143 configured by the first counter 143A, the second counter 143B, and the third counter 143C. The count is started (S61). Further, the time display motor driving means 15 is controlled to execute the above-described indicator 20-second display process (S62).

[Duration display processing in the fourth voltage range]
When the detected voltage Vs is included in the fourth voltage range (Yes in S55), the duration display control unit 145 includes the first counter 143A, the second counter 143B, the third counter 143C, and the timer 143 configured by the fourth counter 143D. An initial value is set to, and counting is started (S63). Further, the time display motor drive means 15 is controlled to execute the above-described indicator 30-second display process (S64).

  The indicator display processes S58, S60, S62, and S64 are normally executed once, but may be continued for a predetermined time (for example, 1 minute) or a predetermined number of times (for example, 4 times). For example, the indicator 5-second display in S58 is a display process in which the second hand 23 is fast-forwarded by 5 seconds and is stopped for 5 seconds from the start of fast-forwarding. However, this process may be performed only once, or 1 minute, that is, 12 It may be performed twice or a predetermined number of times such as four times.

When the detection voltage Vs is included in the BLD voltage range (Yes in S56), the BLD operation mode S30 is executed.
In addition, when it is determined No in S56, since the detection voltage Vs is less than the system stop voltage Von, the operation stop unit 141 stops the hand movement (S65), and the above-described operation stop is an operation process at the time of operation stop. Mode S1 is executed.

  As described above, in the duration display process S50, the duration corresponding to the detection voltage Vs is set in the timer 143, the remaining time starts to be counted, and the indicator display for displaying the set duration is further displayed. Is performed using the second hand 23.

[BLD operation mode]
Next, the BLD operation mode S30 will be described with reference to FIG. In addition, as described above, the BLD operation mode S30 is determined as “Yes” in S7 (FIG. 6), S22 (FIG. 9), S44 (FIG. 10), and S56 (FIG. 11), and S73 (FIG. It is executed when it is determined “No” in 7) (during the operation duration adjustment process).

When the BLD operation mode S30 is executed, the time display control means 14 sets an initial value (24 hours in the present embodiment) in the BLD counter 143E and starts a down count in order to set the duration of the BLD operation. .
Next, the time display control means 14 performs BLD hand movement (S32). The BLD hand movement is, for example, that the second hand 23 is fast-forwarded by 2 seconds every 2 seconds, and it is only necessary to notify the user that a BLD hand movement different from the normal hand movement is being executed.

Next, the time display control unit 14 determines whether or not the charging from the power generation unit 4 to the secondary battery 7 has been detected (S33). Here, if it is determined that there is charge detection, the time display control means 14
It is determined whether the BLD operation mode S30 is determined as No in S73 and is executed, that is, whether the operation duration adjustment process S70 is being performed (S37).
And when it determines with Yes in S37, since there was charge detection in the state which is not performing the predetermined carrying amount and is performing BLD operation mode S30 during driving duration adjustment processing, It returns to the process of S4 at the time of the operation resumption shown in FIG. Accordingly, the operation resuming unit 142 repeats the processes after S4 again.

On the other hand, when it is determined No in S37, the time display control unit 14 determines whether the detected voltage Vs is less than VBLD (S34).
When it is determined No in S34, that is, when the voltage of the secondary battery 7 has returned to a level higher than the BLD voltage range, the time display control unit 14 executes the above-described normal operation mode S20.

When it is determined No in S33 or when it is determined Yes in S34, the time display control unit 14 determines whether or not the remaining time of the BLD counter 143E is greater than 0 hours (S35).
If it is determined Yes in S35, the BLD operation period remains, so the process returns to S32 to continue the BLD hand movement.
On the other hand, when it is determined No in S35, since the BLD operation period has ended, the operation stop unit 141 stops the hand movement (S36) and executes the operation stop mode S1 described above.

According to this embodiment, there are the following effects.
(1) The time display control means 14 includes a portable amount detection unit 147 and an operation duration adjustment unit 148, and the portable amount becomes a predetermined value when the charge state is detected and the operation is restarted from the operation stop state. After confirming this, the timer 143 is set to the operation duration time corresponding to the amount of carry and the detected voltage Vs. That is, after it becomes possible to determine that the user is carrying the electronic timepiece 1, the driving duration adjusting unit 148 sets a predetermined driving duration. Therefore, it is possible to prevent a long operation duration from being set only by temporary charge detection, and it is possible to prevent wasteful consumption of the power of the secondary battery 7.

(2) Further, the operation resuming unit 142 determines the Yes in S8 among the plurality of settable operation durations (1 day, 7 days, 30 days, 180 days), and the shortest operation duration time in S9 ( In cases other than setting to (1 day) (No in S8), the operation duration adjustment processing S70 by the operation duration adjustment unit 148 is executed. Then, the carrying amount detected by the carrying amount detection unit 147 increases from the 2nd to the 7th, or the detection voltage Vs increases, so that the operation duration is set stepwise as 7 days, 30 days, and 180 days. it can. Therefore, when the electronic timepiece 1 is not carried after the operation is resumed, the operation can be stopped at an early stage, and the power consumption of the secondary battery 7 can be suppressed.

(3) When detecting the carrying amount of the electronic timepiece 1, the charge detection means 6 used for resuming operation is used. Therefore, the charge corresponding to the actual capacity of the secondary battery 7 is measured. There is no need to provide an element for detecting the portable state, and the circuit can be configured at low cost.
Furthermore, since the portable amount detection unit 147 sets one day divided into a plurality of time zones and counts the carrying state in a plurality of time zones, it counts that there was a portable amount for one day. It is possible to detect with high accuracy that the user is wearing for 7 hours or more in one day. Therefore, the carrying state can be determined with high accuracy.

(4) Since the duration display control unit 145 and the timer update unit 146 are provided, it is possible to prevent the operation from stopping in a time shorter than the displayed duration when the operation duration is displayed. When the secondary battery 7 is charged, the operation duration can be appropriately adjusted according to the voltage of the secondary battery 7, and convenience can be improved.
That is, when the duration display process S50 is performed by operating the button 8, the duration display control unit 145 resets the timer 143 according to the detection voltage Vs, and displays the duration according to the detection voltage Vs. ing. Since the timer update unit 146 operates only when the state of charge is detected, when the power generation unit 4 does not generate power, the timer update unit 146 ends the normal operation when the displayed duration has elapsed, and the BLD operation mode. Can be migrated to.
For this reason, when there is a high possibility that the power generation means 4 is not operated and the electronic timepiece 1 is not used, the operation state is continued more than necessary and the voltage of the secondary battery 7 is less than the system stop voltage Von. Can be prevented. Further, when there is a high possibility that the power generation means 4 is activated and the electronic timepiece 1 is used, the duration is updated according to the voltage of the secondary battery 7, so that the operation is performed while the electronic timepiece 1 is being used. Stopping can also be prevented and convenience can be improved.
For example, if the timer update unit 146 is operated even when the state of charge is not detected, the duration is always updated as long as the detection voltage Vs is maintained in the same voltage range. Normal operation continues until it drops below VBLD. If the state of charge cannot be detected, there is a high possibility that the electronic timepiece 1 is not being used, so that power is consumed unnecessarily, and the voltage of the secondary battery 7 at the time of operation stop becomes low. There is a high possibility that the secondary battery 7 must be charged, and there is a disadvantage that the electronic timepiece 1 cannot be used immediately.
On the other hand, in the present embodiment, the timer update unit 146 operates only when the state of charge is detected. Therefore, when the electronic timepiece 1 does not detect the charge, the BLD is updated when the set duration has elapsed. The operation can be stopped by shifting to the operation mode S30, the voltage of the secondary battery 7 can be maintained high when the operation is stopped, and the electronic timepiece 1 can be used immediately when the operation is resumed.

(5) Furthermore, the timer update unit 146 newly resets the duration of the timer 143 only when the duration corresponding to the detected voltage Vs is longer than the remaining duration of the operating timer 143.
For this reason, the inconvenience that the normal operation ends before the displayed duration time can be prevented. For example, since the detection voltage in the duration display process S50 is slightly higher than Vind3, after the duration is set to 180 days, charge detection is performed when the operation is performed for 10 days, and the detection voltage Vs is the third voltage. In the voltage range, if the timer is automatically switched to the duration corresponding to the detected voltage Vs at that time, the remaining duration of 170 days is shortened to 30 days. For this reason, since the normal operation ends at a time shorter than the duration recognized by the user, the user cannot trust the displayed duration, and as a result, convenience is impaired.
On the other hand, in the present embodiment, when the duration by the detection voltage Vs is shorter than the remaining duration of the operating timer 143, the operating timer 143 is continuously used, so the displayed duration is Driving can be continued and convenience can be improved.

(6) Furthermore, when the duration corresponding to the detected voltage Vs is longer than the remaining duration of the active timer 143, the timer update unit 146 newly resets the duration of the timer 143. For this reason, when the user performs a manual power generation operation such as by rotating the rotating weight 2 by shaking the electronic timepiece 1 for the purpose of extending the duration, the voltage of the secondary battery 7 rises. The duration according to the voltage value can be newly set. Therefore, it is possible to meet the expectation of the user who performed the power generation operation to extend the duration, and the convenience can be improved in this respect.

(7) When resuming the operation from the operation stop state (sleep mode), the voltage Vs of the secondary battery 7 at the time of resuming the operation is detected, and when the voltage value is greater than or equal to Vind1, the carrying amount and the detected voltage Vs Accordingly, the operation duration is set to 7 days, 30 days, or 180 days. At this time, the higher the detection voltage Vs, the longer the timer is operated. For this reason, appropriate operation resumption processing can be performed according to the detected voltage Vs.
In particular, since the operation duration can be set in consideration of the detection voltage Vs, even if the operation is performed only for the duration without using the power generation unit 4 to generate power, the secondary battery 7 can be operated for the duration. It can be set so that the voltage of the battery 7 does not fall to the system stop voltage Von or the BLD voltage range. For this reason, even when the operation is stopped, the secondary battery 7 can be maintained at VBLD or higher, and when power generation by the power generation means 4 is performed and a charged state is detected, the hand movement can be resumed immediately and the user can be resumed. Can check time and improve convenience.

(8) As the timer 143, four timers (counters) of the first to fourth counters 143A to 143D are provided, and each counter 143A to 143D is set corresponding to each voltage range Vr1 to Vr4. The design structure of the timer 143 can be simplified as compared with the case where only one timer is provided and different durations are counted.
That is, when managing a plurality of durations with a single timer, it must be designed so that different durations can be set. On the other hand, in this embodiment, it is only necessary to set an initial value that is the maximum value that can be counted by each of the counters 143A to 143D, and the design structure of the timer can be simplified.

(9) In the present embodiment, the timer 143 continues to operate even when the time is adjusted by the crown 3 or the like. For this reason, for example, even when the electronic timepiece 1 is left with the crown 3 pulled in two steps and left in the time adjustment state, the timer 143 operates and the operation is stopped when the duration becomes 0. It can prevent that the voltage of the secondary battery 7 falls below the system stop voltage Von.

[Second Embodiment]
In the first embodiment, the carrying amount is detected by detecting the charging state. However, in the electronic timepiece 1A of the second embodiment, the carrying amount is detected by detecting the continuous charging state of the electronic timepiece 1A. Is. That is, when power is generated using the rotating weight 2, the rotating weight 2 can be rotated to generate power by dropping the electronic timepiece 1A by hand. For this reason, when the user starts to use the electronic timepiece 1A in the operation stop state, the user quickly performs a quick charge operation to quickly increase the voltage of the secondary battery 7 by performing several tens to hundreds of continuous gestures. May do. As described above, when hand gestures of several tens to several hundreds of times are continuously performed, the user intends to carry the electronic timepiece 1A and is mostly performed as a quick charging operation before use. Accordingly, the carrying amount can be estimated by the number of continuous hand gestures, and the driving duration can be adjusted.

  Therefore, as shown in FIG. 13, the electronic timepiece 1 </ b> A includes an acceleration sensor that detects a hand shake state as a charge detection unit that detects a continuous state of charge in addition to the configuration of the electronic timepiece 1 of the first embodiment. (Hand shake detection means) 110 is provided. The charge detection means for detecting the continuous charge state is not limited to the acceleration sensor 110, but a current detection means (charge detection means 6) or a voltage detection means for detecting the charging current or voltage to the secondary battery 7 is used. You can also

  In addition, the time display control unit 14 includes a hand movement amount detection unit 149 to which a hand movement detection signal output from the acceleration sensor 110 is input. The hand shake amount detection unit 149 counts the time during which the hand shake detection signal is in the detection state with a 1 Hz clock, and outputs the continuous count number to the driving duration adjustment unit 148. That is, the hand shaking amount detection unit 149 confirms whether the hand shaking state continues every second, and updates the count number when it continues. Therefore, the hand movement amount detection unit 149 constitutes a portable amount detection unit that detects a continuous charge state and detects the continuous charge detection time as a portable amount.

In addition, as conditions for determining the continuous charging state, not only the case where the hand shaking state is continuously detected every sampling of state detection (every 1 second), but also the period during which the hand shaking state cannot be continuously detected. Even in such a case, it is a case where the time is equal to or shorter than a predetermined period (for example, 10 seconds), and the continuous charging state may be determined also when the hand shaking state is continuously detected again.
Even if there is a period during which the hand shaking state cannot be continuously detected, it may be determined that the battery is continuously charged when the set number of hand shaking states are counted within the set time from the start of detecting the hand shaking state. For example, when the count corresponding to the carrying amount for one day is 200, if the detection is continuously performed every second, the count is reached in 200 seconds. In this case, for example, if the set time is set to 600 seconds (10 minutes) and the detection count of the hand gesture state reaches 200 within 600 seconds from the start of detection of the hand shake state, it is determined that the battery is continuously charged. May be. This is because if the carrying amount for one day is achieved in 10 minutes, it can be said to be a quick charge state, and there is no problem even if it is determined as a continuous charge state.

  On the other hand, since the electronic timepiece 1A according to the second embodiment does not detect the amount of carry in the charged state as in the first embodiment, the time display control means 14 includes the first adjustment period counter 147A, the second The adjustment period counter 147B and the portable amount detection unit 147 are not provided.

Next, processing at the time of restarting operation in the second embodiment will be described with reference to the flowchart of FIG.
Similar to the first embodiment, in the operation stop mode, only the charge detection means 6 is operated, and the charge detection means 6 determines whether or not there is charge detection (S2). And if it determines with Yes in S2, IC operation stop function will be canceled (S3).

Next, when the state of charge is detected by the operation duration adjusting unit 148 shaking the electronic timepiece 1 to generate power, the operation resuming unit 142 sets an initial value in the first counter 143A and sets the operation duration. Set to one day and start counting (S101) . Further, the display is set to 5 seconds corresponding to the operation duration for one day, and the charge amount indicator is displayed by the second hand 23 (S102).

Next, the driving duration adjustment unit 148 confirms a change in the count number of the hand movement amount detection unit 149 and determines whether a continuous charging state is detected (S103).
If it determines with Yes in S103, the driving duration adjustment part 148 will determine whether the count number of the hand-shake amount detection part 149 became more than a 1st threshold value (S104). In the case of No in S104, the process returns to S103 and continues.

When it is determined Yes in S104, that is, when the count number of the hand movement detection state reaches the first threshold, the driving duration adjustment unit 148 sets initial values to the first counter 143A and the second counter 143B. The operation duration is set to 7 days and the count is started (S105). The first threshold value may be set to the number of times corresponding to the charge amount (power generation amount) when the electronic timepiece 1A is carried around for one day. For example, if the first threshold is 200 times, the count value reaches the first threshold when the hand shake detection state continues for 200 seconds. For this reason, since it can be judged that the user intends to carry it for one day or more, the driving duration is ranked from the shortest day to the next stage, the seventh day.
For this reason, the operation duration adjustment unit 148 sets the charge amount indicator display to a 10-second display corresponding to the operation duration for 7 days (S106).
Note that if the user exercises while wearing the electronic timepiece 1A on his / her wrist, a continuous charge state may be detected without the user's intention. Also in this case, if the conditions of S103 and S104 are satisfied, the processes of S105 and S106 may be performed.

  The operation duration adjustment unit 148 further determines whether a continuous charge state is detected (S107). When it determines with Yes by S107, the driving duration adjustment part 148 determines whether the count number of the hand-shake amount detection part 149 became more than a 2nd threshold value (S108). If No in S108, the process returns to S103 and continues.

When it is determined Yes in S108, that is, when the count reaches the second threshold, the operation duration adjustment unit 148 sets initial values to the first counter 143A, the second counter 143B, and the third counter 143C. Then, the operation duration is set to 30 days and the count is started (S109).
In addition, the operation duration adjusting unit 148 sets the charge amount indicator display to a 20-second display corresponding to the operation duration for 30 days (S110). In the present embodiment, the second threshold corresponds to a charge amount (power generation amount) when the electronic timepiece 1 is carried for 7 days. For example, when the first threshold value corresponding to the charge amount for one day is 200 times, the second threshold value is 200 times × 7 days = 1400 times. In this case, since the user can determine that he / she intends to carry it for more than 7 days, the driving duration is ranked up to 30th, which is the next stage on the 7th. In addition, what is necessary is just to process similarly when it corresponds to conditions by exercise | movement.
In the second embodiment, the driving duration is kept up to the rank of up to 30 days. However, when the hand gesture detection state continues and the count number becomes high, the next driving duration is 180 days. You may rank up.

  The operation duration adjustment unit 148 performs the operation duration adjustment process from S103 to S110 when it is determined in S103 and S107 that a continuous charge state is not detected and when the process of S110 is performed. And the process proceeds to the normal operation mode S20.

In the second embodiment as described above, the same effects as those of the first embodiment can be obtained. That is, when the driving is resumed, the driving duration is adjusted based on the count value of the hand movement detection state corresponding to the carrying amount, so that the same effect as that of the first embodiment can be obtained.
Further, by displaying the indicator with the second hand 23 during the hand movement of the electronic timepiece 1A, the user can determine how long the time has been set by charging by hand gesture and can easily confirm whether the hand gesture operation is continued. .

[Third Embodiment]
Next, a third embodiment of the present invention will be described.
As shown in FIG. 15, the electronic timepiece 1 </ b> B of the third embodiment includes a carrying amount detection process and a driving duration setting process according to the detection of the state of charge of the first embodiment, and a continuous process of the second embodiment. This is a combination of carrying amount detection processing by charge detection and driving duration setting processing. For this reason, in the electronic timepiece 1B, an acceleration sensor 110 and a hand movement amount detection unit 149 are added to the electronic timepiece 1 of the first embodiment.

According to the electronic timepiece 1B, for example, when the user of the electronic timepiece 1B in the stopped state first performs a hand gesture operation to release the stopped state, the IC stopped state is released by charge detection, and the normal hand movement display is displayed. Start. When the count value in the hand gesture detection state becomes the first threshold value, the driving duration adjustment unit 148 ranks the driving duration to 7 days (indicator display is 10 seconds).
Thereafter, when the electronic timepiece 1B is carried and the state in which the daily carrying amount is detected can be confirmed for 7 days, the driving duration adjusting unit 148 sets the driving duration to 30 days (the indicator display is 20 seconds). Rank up.

  Thus, if two types of detection methods for carrying amount are provided, it is possible to appropriately detect both the case where power generation is performed with the user's intention of hand movement detection and the case of automatic power generation in a normal carrying state. Thus, the operation duration adjustment process when the operation is resumed can be appropriately executed, and the convenience can be improved.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described.
In each of the embodiments described above, the driving duration adjustment unit 148 is configured to be able to adjust the driving duration in multiple stages of 7 days, 30 days, and 180 days, but in this embodiment, the driving duration is set to one stage. Is set. That is, the electronic timepiece 1 of the fourth embodiment has the same configuration as that of the first embodiment, but only the operation duration adjustment process is changed to the process shown in FIG.
In the driving duration adjustment process S200, the driving duration adjustment unit 148 initializes the carry amount C2 to “0” (S201), and when the daily carry amount detection process S90 is performed, is C2 greater than 0? Is determined (S202).
If it is determined Yes in S202, the operation duration adjustment unit 148 sets initial values in the first counter 143A and the second counter 143B, sets the operation duration to 7 days, and starts counting. (S203), the process proceeds to the normal operation mode S20.
On the other hand, when it is determined No in S202, the operation duration adjustment unit 148 executes the BLD operation mode S30.

Also in the fourth embodiment, in the normal operation mode, when the voltage of the secondary battery 7 is charged by the power generation means 4 and the voltage of the secondary battery 7 is increased, the operation duration is adjusted according to the level of the detection voltage Vs, thereby generating power. In addition, the operation duration according to the voltage level of the secondary battery 7 can be set.
In short, the present invention does not immediately set a relatively long (for example, 7 days or more) driving duration by temporary charge detection, and does not enter the normal driving mode. It is only necessary that the operation duration can be extended when it is confirmed that the user is using the watch 1.
Also in the fourth embodiment, when it is determined Yes in S202, the operation duration may be selected based on the detected voltage Vs at that time.

It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, in the above-described embodiment, the operation duration adjusted by the operation duration adjustment unit 148 when the operation is resumed is the same as four operation durations that can be set in the normal operation mode, that is, 1, 7, 30, and 180 days. However, the stage number and value of the adjustable operation duration may be different from those in the normal operation mode.
Further, the operation duration adjustable by the operation duration adjustment unit 148 may be 7 days and 15 days, and the number of steps may be reduced or set to a different duration. In addition, the operation duration adjustable by the operation duration adjustment unit 148 may be 7 days, 15 days, 30 days, 60 days, 120 days, 180 days, and the number of steps may be increased or different durations may be set. .

  In the embodiment, the counters 143A to 143D for counting the operation duration, and the first adjustment period counter 147A and the second adjustment period counter 147B that are used when restarting the operation are configured with different counters. It may be realized using the same counter.

  When the duration of the normal operation set by the timer 143 in accordance with the detection voltage Vs reaches 0 hour, the normal operation is stopped and the mode is shifted to the BLD operation mode. In the BLD operation mode, a predetermined time (24 hours in the above embodiment) is set. ) The operation is stopped when it has elapsed, but the operation may be stopped when the duration of the normal operation reaches 0 hours without shifting to the BLD operation mode.

The voltage range for determining the detection voltage Vs is not limited to the first to fourth voltage ranges.
