Description

The present invention relates to an electronic clock, a reception operation control method and a program.

Conventionally, there are electronic clocks capable of receiving radio waves from positioning satellites to acquire accurate date and time information and to acquire the current position. With this electronic clock, date and time information can be periodically acquired from the outside to maintain accurate date and time counting. In addition, it is possible to acquire the date and time at a desired timing based on the input operation of the user, and to acquire and update the local time setting such as the current position, the time zone according to the current position, and the daylight saving time implementation rule.

However, in electronic watches, especially small portable ones such as wristwatches, there are restrictions on the number of configurations related to the reception of operations and the contents of possible operations, and it is attempted to perform many functions based on user operations. , There is a problem that the operation content tends to be complicated. On the other hand, when receiving radio waves from the positioning satellite according to the duration of the predetermined operation, the operation of acquiring only the date and time information without including the current position information, or the operation of acquiring the date and time information and the position information together. An electronic clock capable of switching between the above and the following is disclosed (Patent Document 1).

Since electronic clocks often require the current position information less frequently than when date and time information is acquired, the duration of a predetermined operation is a predetermined standard in consideration of user convenience. When the time is shorter than the time, only the date and time information is acquired, and when the duration is longer than the reference time, the position information is also acquired.

However, with such an electronic watch, the reception conditions may change significantly in a short time due to the movement of the user who wears it, and especially when it takes time to acquire necessary information such as positioning operation, the user is long-term. There is a problem that the user's convenience is impaired because the reception environment is not maintained and reception fails as a result of forcing the user to wait for a while or moving the user.

The host control unit 41 includes a host CPU 411, a RAM 412, and the like, performs various arithmetic processes and stores and holds data, and controls the operation of the electronic clock 1 by the microcomputer 40 in an integrated manner. The host CPU 411 is a processor that performs arithmetic processing. The RAM 412 is a volatile memory that provides a working memory space to the host CPU 411 and stores temporary data. The RAM 412 may include a non-volatile memory that can be rewritten and updated.

The oscillation circuit 44 generates a predetermined frequency signal and outputs it to the frequency dividing circuit 45. The oscillation circuit 44 includes, for example, a crystal oscillator and generates a signal of about 16 kHz or about 32 kHz. The crystal oscillator may be externally attached to the microcomputer 40.

The frequency dividing circuit 45 divides a predetermined frequency signal input from the oscillation circuit 44, converts it into a frequency signal used by the host CPU 411, the timekeeping circuit 46, etc., and outputs the frequency signal to the host CPU 411, the timekeeping circuit 46, or the like.

The timekeeping circuit 46 counts and holds the current date and time (time) by counting the signals input from the frequency dividing circuit 45. There is a slight error in the counting date and time of the timekeeping circuit 46, for example, about ± 0.5 seconds per day. The date and time counted by the timekeeping circuit 46 can be modified according to an instruction from the host CPU 411.

The satellite radio wave reception processing unit 50 includes a reception unit 51, a module control unit 52, a storage unit 53, and the like, and performs a predetermined processing operation for acquiring date and time information (time information) and position information. The receiving unit 51 captures and receives radio waves from the positioning satellite and demodulates the navigation message. The module control unit 52 acquires date and time information, position information of each positioning satellite, and the like based on a navigation message obtained from radio waves from the positioning satellites captured by the receiving unit 51. Further, the module control unit 52 is provided with a CPU, RAM, and the like, and performs positioning to calculate the current position of the own machine by using the acquired date and time information and the position information of each positioning satellite. The storage unit 53 stores and holds various setting data related to the reception operation, a control program related to the operation of the module control unit 52, and the like.

The power consumption (current consumption, load) required for the operation related to the positioning by the satellite radio wave reception processing unit 50 and the power consumption per time until the positioning operation is completed are electronic such as the date and time counting operation and the display operation by the display unit 62. It is significantly larger than the other operations in the clock 1.

The ROM 64 stores setting data and a program 641 related to various operations of the electronic clock 1. The program 641 includes a reception operation control program that controls the operation of the satellite radio wave reception processing unit 50 according to the operation content received by the operation reception unit 61. The ROM 64 has a non-rewritable memory such as a mask ROM, an updatable non-volatile memory such as a flash memory, or both.

The operation reception unit 61 receives an input operation from the outside (user) and outputs it as an input signal to the host CPU 411. The operation receiving unit 61 has one or a plurality of push button switches 611 as a configuration for receiving an input operation from the outside. Further, the operation reception unit 61 may have a crown, a touch panel, or the like.

The display unit 62 displays various information according to the control of the host CPU 411. The display unit 62 can display at least the current time based on the date and time counted by the timekeeping circuit 46. The display unit 62 may be provided with, for example, a plurality of pointers (hour hand, minute hand, second hand, etc.), or may be provided with a configuration capable of digital display on a liquid crystal screen or the like.

The notification operation unit 63 performs a predetermined notification operation based on the control of the host CPU 411. Examples of the notification operation unit 63 include a beep sound generation unit that generates a beep sound, a light emitting unit that performs a light emitting operation, and a combination thereof.

The power supply unit 70 supplies electric power from the battery 71 to each unit such as the microcomputer 40 and the satellite radio wave reception processing unit 50. The battery 71 may have a power generation unit included in the electronic clock 1 and a secondary battery charged by the generated electromotive force of the power generation unit, or a button type that can be attached to and detached from the electronic clock 1 by the user. It may be a battery or the like. Examples of the power generation unit include a solar power generation unit. Here, it is desirable to use a lightweight and compact battery 71 in order to reduce the weight and size of the electronic clock 1.

Next, the radio wave reception operation from the positioning satellite, which is the reception operation control method in the electronic clock 1 of the present embodiment, will be described.
In the electronic clock 1, the duration of the pressed state (predetermined input operation) of the predetermined push button switch 611 is equal to or longer than the first reference time (for example, 1.5 seconds) and is longer than the first reference time (second reference time). For example, if it is less than 3.0 seconds), the date and time are acquired, and if the pressing duration of the predetermined push button switch 611 is 3.0 seconds or more, the position information is acquired.
Of these configurations, the host control unit 41 and the module control unit 52 form the control unit in the electronic clock 1 of the present embodiment.

FIG. 2 is a diagram illustrating an operation switching state of the satellite radio wave reception processing unit 50 according to the pressing duration in the electronic clock 1 of the present embodiment.
In the electronic clock 1, when the pressing duration exceeds the first reference time (1.5 seconds), the satellite radio wave reception processing unit 50 is activated and the reception operation is started. At this time, the satellite radio wave reception processing unit 50 first starts a reception operation of information necessary for the positioning operation (first operation related to acquisition of the current position) after the initial setting. Then, as shown in FIG. 2A, when the pressing operation of the predetermined push button switch 611 is released before the second reference time (3.0 seconds) or more, the positioning operation (current position) is performed. At the stage (second operation) in which only the date and time (date and time information not including the current position) is acquired without completing the acquisition (first operation), the information related to the date and time not including the current position is transmitted to the host CPU 411. Output and end the reception operation.

On the other hand, as shown in FIG. 2B, when the pressing duration exceeds the second reference time (3.0 seconds), the satellite radio wave reception processing unit 50 continues to acquire information and positions the position. It operates and outputs position information according to the positioning result to the host CPU 411.

When receiving radio waves from a positioning satellite related to GPS (Global Positioning System) and decoding the transmitted signal to acquire necessary information, the date and time information is the beginning of each subframe transmitted every 6 seconds. Included in 2 nearby words (1.2 seconds). Therefore, the date and time information that does not include the position information is acquired in about 1.5 seconds after starting to track the radio wave from the positioning satellite, and in about 6.0 to 7.5 seconds at the maximum. On the other hand, the orbit information of each positioning satellite required for acquiring the current position information is included in the second and third signals of the five subframes (30 seconds in total) transmitted in order. Therefore, in order to acquire the position information, it is necessary to receive the date and time information (the first two words mentioned above) for specifying the current position of the positioning satellite for a total of about 12 seconds and a maximum of about 30 to 42 seconds. Become.

FIG. 3 is a flowchart showing a control procedure by the host control unit 41 of the reception operation control process executed by the electronic clock 1 of the present embodiment.
This reception operation control process is called and executed at the timing when the pressing duration of the predetermined push button switch 611 is 1.5 seconds or more.

When the reception operation control process is started, the host control unit 41 (host CPU 411) activates the satellite radio wave reception processing unit 50 (step S101). The host control unit 41 outputs a positioning command to the activated satellite radio wave reception processing unit 50 (step S102; positioning operation start step, positioning operation start means). When the start command and the positioning command can be issued at the same time, the host control unit 41 may execute the activation command and the positioning command at the same time.

The host control unit 41 determines whether or not 3 seconds or more have elapsed from the start of the pressing operation of the predetermined push button switch 611 (step S103). If it is determined that 3 seconds or more have elapsed (“YES” in step S103), the process of the host control unit 41 proceeds to step S106.

If it is determined that 3 seconds or more have not passed since the start of the pressing operation (“NO” in step S103), the host control unit 41 determines whether or not the pressing operation has been released (step S104). If it is determined that the release has not been released (“NO” in step S104), the process of the host control unit 41 returns to step S103.

When it is determined that the pressing operation of the predetermined push button switch 611 is released (“YES” in step S104), the host control unit 41 issues a command to the satellite radio wave reception processing unit 50 to change the date and time acquisition. Output (step S105; operation change step, operation change means). Then, the process of the host control unit 41 shifts to step S106.

When the process of step S103 or step S105 shifts to the process of step S106, the host control unit 41 waits for the signal input from the satellite radio wave reception processing unit 50 and acquires the result output from the satellite radio wave reception processing unit 50. (Step S106). The host control unit 41 appropriately performs processing based on the acquisition result, that is, correction of the counting date and time of the timekeeping circuit 46, change of the display date and time, and the like.

The host control unit 41 stops the operation of the satellite radio wave reception processing unit 50 (step S107). Then, the host control unit 41 ends the reception operation control process.

FIG. 4 is a flowchart showing a control procedure by the module control unit 52 of the reception control process executed by the satellite radio wave reception processing unit 50.
This reception control process is also started when the satellite radio wave reception processing unit 50 is activated by the control of the host CPU 411.

When the reception control process is started, the module control unit 52 makes initial settings related to the operation of the satellite radio wave reception processing unit 50 (step S201). Initial settings include programs required for receiving operations, settings, and data reading. The data to be read may be stored in the ROM 64 in addition to the storage unit 53.

The module control unit 52 starts the reception unit 51 and starts the reception operation (step S202). The module control unit 52 starts the operation of the radio wave from the positioning satellite. Further, "3" is set as the number of target satellites N (number of radio waves) to be captured. When considering altitude, it may be set to "4".

The module control unit 52 determines whether or not the acquisition operation is being executed and the radio wave from the positioning satellite is newly acquired (step S203). If it is determined that the capture operation has already been completed or the radio waves from the new positioning satellite have not been captured (“NO” in step S203), the processing of the module control unit 52 shifts to step S205. To do.

If it is determined that the radio wave from the new positioning satellite has been captured during the capture operation (“YES” in step S203), the module control unit 52 performs the tracking operation of the radio wave from the captured positioning satellite. Is started (step S204). Then, the process of the module control unit 52 shifts to step S205.

When the process shifts to the process of step S205, the module control unit 52 determines whether or not the change instruction for acquiring the date and time has been acquired (step S205). If it is determined that the module has not been acquired (“NO” in step S205), the process of the module control unit 52 proceeds to step S207. If it is determined that the satellite has been acquired (“YES” in step S205), the module control unit 52 changes (decreases) the value of the number of target satellites N to “1” (predetermined lower limit) (step S206). ). Then, the process of the module control unit 52 shifts to step S207.

When the process proceeds to step S207, the module control unit 52 determines whether or not the number of radio waves from the currently captured positioning satellites is equal to or greater than the number of target satellites N (step S207). If it is determined that the number of target satellites is not N or more (“NO” in step S207), the process of the module control unit 52 returns to step S203. When it is determined that the number of target satellites is N or more (“YES” in step S207), the module control unit 52 ends the capture operation (step S208). When radio waves from multiple positioning satellites are captured at the same time, or when the number of target satellites N is changed (decreased) from "3" to "1", radio waves from the captured positioning satellites are captured. When the number of radio waves is larger than the number of target satellites N, the module control unit 52 selects radio waves from positioning satellites equal to the number of target satellites N in a predetermined condition, for example, in descending order of reception intensity. , It may be possible to stop tracking the remaining captured radio waves.

The module control unit 52 determines whether or not the necessary information has been acquired (step S209). If it is determined that the module has not been acquired (“NO” in step S209), the process of the module control unit 52 returns to step S203. If it is determined that it has been acquired (“YES” in step S209), arithmetic processing, for example, positioning arithmetic is performed as necessary to acquire the result requested by the host control unit 41. The module control unit 52 outputs the obtained result to the host control unit 41 at an appropriate timing, for example, every positive second (timing when a value less than a second digit is 0) (step S210).

The module control unit 52 ends the reception operation by the reception unit 51 (step S211), and ends the reception control process.

Here, it was decided that the capture operation would end when the radio waves from one positioning satellite were captured when the date and time information was acquired, and the radio waves from three positioning satellites were captured when the information related to the current position was acquired. Since the accuracy of the acquired information improves as the number of captured satellites increases, it is necessary to capture more radio waves from positioning satellites according to predetermined conditions, such as the duration of the capture operation and the standard of radio wave reception intensity. May be.

As described above, the electronic clock 1 of the first embodiment has a receiving unit 51 that receives radio waves from a positioning satellite, a control unit that includes a host control unit 41 and a module control unit 52, and an operation reception that accepts user operations. A unit 61 is provided. When the duration of the pressing operation of the predetermined push button switch 611 received by the operation receiving unit 61 exceeds the first reference time (1.5 seconds), the control unit receives the current position by the receiving unit 51. If the first operation related to acquisition is started and the pressing operation is completed before the duration becomes the second reference time (3.0 seconds) longer than the first reference time, the date and time not including the current position The operation of the receiving unit 51 is changed so as to perform the second operation related to the acquisition of information.
In this way, when it is decided to perform the radio wave reception operation, the reception operation related to the positioning operation is first started, and when the positioning is no longer necessary, the positioning operation is not completed and only the date and time information is acquired. And end the reception. As a result, since the operation related to the positioning is started before the positioning operation is confirmed, the time until the acquisition of the current position information is completed can be shortened. On the other hand, even if the positioning operation is not performed, it is possible to shift to the date and time information acquisition operation by utilizing the time required for the activation operation and the acquisition operation of the receiving unit 51 or by utilizing the result of the acquisition operation. It does not unnecessarily significantly increase the power consumption and reception time of unit 51. Further, in particular, the second reference time that does not normally make the user feel stress is about twice the first reference time, which is about 1 to 2 seconds, and it is assumed that the time until the date and time information is acquired is slightly extended. However, the time is sufficiently short compared to the positioning operation. That is, it is sufficiently unlikely that the reception environment will change significantly within this time and it will be difficult to acquire the date and time information. Therefore, it is possible to improve the convenience of the user related to the radio wave reception operation in the electronic clock 1.

Further, when the control unit changes the operation of the receiving unit 51 to the operation related to the acquisition of only the date and time, the control unit reduces the number of radio waves of the positioning satellite to be captured to a predetermined lower limit number "1" and is captured. When the number of radio waves is larger than this lower limit, the lower limit number of radio waves is selected under a predetermined condition, and the operation related to the acquisition of the date and time information not including the current position is performed.
If the acquisition operation is changed to acquire date and time information when radio waves from two or more positioning satellites have already been captured by the capture operation according to the positioning operation, the preferred one of the captured radio waves is used as it is for the date and time. Since the information can be acquired, the date and time information can be acquired reliably and stably without wasting the capture operation.

Further, the reception operation control method of the electronic clock 1 of the present embodiment receives when the duration of the pressing operation of the predetermined push button switch 611 received by the operation receiving unit 61 exceeds the first reference time. The positioning operation start step for starting the first operation related to the acquisition of the current position by the unit 51, and the pressing operation of the predetermined push button switch 611 are completed before the duration becomes the second reference time longer than the first reference time. If so, the operation change step of changing the operation of the receiving unit 51 so as to perform the second operation related to the acquisition of the date and time information not including the current position is included.
In this way, when it is decided to perform the radio wave reception operation, the reception operation related to the positioning operation is first started, and when the positioning is unnecessary, only the date and time information is acquired without completing the positioning operation. To end reception. As a result, since the operation related to the positioning is started before the positioning operation is confirmed, the time until the acquisition of the current position information is completed can be shortened. On the other hand, even if the positioning operation is not performed, the receiving unit 51 can be shifted to the date and time information acquisition operation by utilizing the time required for the activation operation and the capturing operation of the receiving unit 51 or by utilizing the capturing operation. Does not unnecessarily increase power consumption or reception time. Therefore, it is possible to improve the convenience of the user related to the radio wave reception operation in the electronic clock 1.

Further, in the program 641 related to the control of the reception operation, the duration of the pressing operation of the predetermined push button switch 611 received by the operation receiving unit 61 of the computer of the electronic clock 1 becomes longer than the predetermined first reference time. In this case, the positioning operation starting means for starting the first operation related to the acquisition of the current position by the receiving unit 51, when the pressing operation is completed before the duration becomes the second reference time longer than the first reference time. As an operation changing means for changing the operation of the receiving unit 51 so as to perform the second operation related to the acquisition of the date and time information not including the current position.
In this way, by performing the reception operation control by software, the reception target can be easily and appropriately switched according to the user operation, and in particular, the time from the start of the input operation related to the radio wave reception command to the completion of positioning can be set. It can be shortened more. As a result, it becomes possible to acquire the current position information more quickly and more reliably than in the past, and it is possible to improve the convenience of the user.

[Second Embodiment]
Next, the electronic clock 1 of the second embodiment will be described.
The functional configuration of the electronic clock 1 of the second embodiment is the same as that of the electronic clock 1 of the first embodiment, and the description thereof will be omitted assuming that the same reference numerals are used.

Next, the control of the reception operation in the electronic clock 1 of the second embodiment will be described.
FIG. 5 is a flowchart showing a control procedure by the host control unit 41 of the reception operation control process executed by the electronic clock 1 of the second embodiment.
This reception operation control process is the same as the reception operation control process executed by the electronic clock 1 of the first embodiment, except that the process of step S105 is replaced with the process of steps S105a and S105b. The same processing contents are designated by the same reference numerals and the description thereof will be omitted.

When the determination process in step S104 is branched to "YES", the host control unit 41 (host CPU 411) interrupts the operation of the satellite radio wave reception processing unit 50, that is, the positioning operation, and restarts the operation (step S105a). The host control unit 41 transmits a date / time acquisition command to the satellite radio wave reception processing unit 50 (step S105b). Then, the process of the host control unit 41 shifts to step S106.

FIG. 6 is a flowchart showing a control procedure by the module control unit 52 of the reception control processing executed by the satellite radio wave reception processing unit 50 of the electronic clock 1 of the second embodiment.
In this reception control process, the pressing operation is canceled before the pressing operation time reaches 3.0 seconds, in addition to when the pressing operation time has passed 1.5 seconds and is called and activated by the host control unit 41. It is also called when it is restarted by the process of step S105a.
In this reception control process, the process in step S202 is replaced with the process in steps S202a and S202b, and the process in step S202 is replaced with the process in step S202b, as compared with the reception control process executed by the satellite radio wave reception processing unit 50 of the electronic clock 1 of the first embodiment. The processes of steps S205 and S206 have been deleted. Other processes are the same, and the description will be omitted assuming that the same reference numerals are used.

Following the process of step S201, the module control unit 52 sets the acquisition target to the date and time or the current position according to the acquisition target setting command input from the host control unit 41, that is, the operation is related to the acquisition of the current position. It is defined as either the operation of 1 or the second operation related to the acquisition of date and time information not including the current position, and the number of target satellites N is set to "1" or "3" according to the setting (step S202a). The module control unit 52 activates the receiving unit 51 to start the receiving operation, and starts the capturing operation of the radio wave from the positioning satellite (step S202b).

At this time, if the module control unit 52 is restarted after the radio waves from the positioning satellite are captured in the reception operation related to the acquisition of the current position, the captured radio waves (when a plurality of the captured radio waves are captured). Information (positioning satellites) related to (1 or more may be selected under predetermined conditions) can be stored and retained, and recaptured preferentially. At this time, the phase of the C / A code can also be reused.
Further, when the phase of the signal already received (that is, the reception timing at the beginning of each subframe) is specified in the reception operation related to the acquisition of the current position, the module control unit 52 sends the beginning of each subframe. The receiving unit 51 can be activated by back-calculating the time of the initial operation and the capturing operation so that the tracking operation can be started according to the timing of. Then, the process of the module control unit 52 shifts to step S203.

When branching to "NO" in step S203, and after the process in step S204, the process in step S207 is executed.

As described above, in the electronic clock 1 of the second embodiment, the control unit restarts the receiving unit 51 when changing the operation of the receiving unit 51 to the operation related to the acquisition of date and time information. By such a simple process, the time until the completion of the positioning operation can be shortened without deteriorating the convenience of the user.

Further, when changing the operation of the receiving unit 51 to the operation related to the acquisition of date and time information, the control unit stores at least one of the positioning satellites that transmit the radio waves captured at the time of the change. After restarting, the radio waves from the stored positioning satellite are preferentially captured. As a result, the time required for acquisition can be shortened, and the radio waves from the positioning satellite can be easily and more reliably acquired to acquire the date and time information.

The present invention is not limited to the above embodiment, and various modifications can be made.
For example, in the above embodiment, the description has been made based on the pressing duration of the predetermined push button switch 611, but the present invention is not limited to this as long as the operation is continued. For example, the duration of the rotation operation of the crown or the contact time of the touch panel at a predetermined position may be used.

Further, in the above embodiment, when the acquisition of the date and time information is changed, the radio waves from the positioning satellite captured at the start of the positioning operation are preferentially reacquired. It is not necessary to perform the operation.

Further, in the above embodiment, it is said that the timing at which the module control unit 52 activates the reception unit 51 can be adjusted so that the tracking can be started at an appropriate timing when the satellite radio wave reception processing unit 50 is restarted. By restarting the satellite radio wave reception processing unit 50 at an appropriate timing, the host control unit 41 tracks the reception unit 51 at an appropriate timing even if the module control unit 52 does not control the reception timing of the reception unit 51. The operation may be started.

Further, in the above embodiment, the case of receiving radio waves from GPS satellites has been described as an example, but the case of receiving radio waves from other positioning satellites such as GLONASS to acquire information related to the date and time and the current position. However, the same processing can be performed.

Further, in the above description, various non-volatile memories such as flash memory and EEPROM are used as a computer-readable medium for storing the program 641 of the reception operation control process related to the process operation of the host control unit 41 (host CPU 411) according to the present invention. The ROM 64 having the above is described as an example, but the present invention is not limited thereto. As other computer-readable media, HDDs (Hard Disk Drives) and portable recording media such as CD-ROMs and DVD discs can be applied. A carrier wave is also applied to the present invention as a medium for providing data of a program according to the present invention via a communication line.
In addition, specific details such as the configuration, control contents, and procedures shown in the above-described embodiment can be appropriately changed without departing from the spirit of the present invention.
