Description

Description: TECHNICAL FIELD The present invention relates to a pedometer with a function of calculating calorie consumption.

[Prior Art] A conventional pedometer with a function of calculating calorie consumption is 1
The calorie consumed can be obtained from the number of steps taken each day, and conversely, the number of steps for consuming the target calorie can be calculated. However, calorie consumption is not determined solely by the number of steps, but also by the pace of walking. For this reason, even if the number of steps is known, depending on the pace of walking, there is a case where it is not possible to consume the target calories even if the user walks more than the target number of steps.
In other words, the conventional pedometer with the calorie consumption calculation function has a problem in that it is not possible to know how fast the user can consume the desired calorie. And the pace at which you burn your calories
Depending on your stride length, weight and target calorie settings,
In the past, it was difficult to accurately indicate this pace.

[Problems to be Solved by the Invention] The present invention has been made in view of the above points, and an object of the present invention is to notify a pace required to achieve a set goal of calorie consumption. It is to provide a pedometer that can be used.

Means for Solving the Problems In order to achieve the above object, the present invention provides a target calorie setting unit for setting a target calorie consumption, and an actual walking time for setting a time at which a user performs a walking motion as an actual walking time. Setting means, an arithmetic circuit for determining a walking pitch required to consume the target calorie consumption based on the target calorie consumption and the actual walking time, and a pitch instruction for instructing the walking pitch obtained by the arithmetic circuit by sound Means.

(Operation) The present invention has the above-described configuration, and allows the user to set the target calorie consumption of the user and the actual walking time during which the user can walk, and obtain the walking pitch from the information set by the user. Therefore, the calorie consumption and the walking time, which are the elements of most interest to the user, can be set, thereby improving the usability.
In particular, the ability to set the walking time allows users to know how much pitch to walk in order to achieve the target calorie consumption within a limited time, and users who have limited time to walk for exercise purposes Can improve the usability. Moreover, if the user walks in accordance with the pitch issued by the pitch instruction means, the user can walk at a pace for consuming the target calorie consumption, thereby consuming more calories than the conventional pedometer. Is made possible.

(Embodiment) FIGS. 1 to 8 show an embodiment of the present invention. FIGS. 6 and 7 show a state in which the pedometer A of the present embodiment is mounted on the belt B. FIG. The pedometer A is composed of an attachment 2 detachably attached to the belt B, and a pedometer main body 1 rotatable about 90 degrees with respect to the attachment. This pedometer A
Is normally used in the state shown in FIG. 6, and is opened in the state shown in FIG. 7 when setting or checking. A hook 4 is provided on the pedometer main body 1, and the hook 4 is engaged with the hook engaging hole 6 of the fixture 2 so that the pedometer main body 1 is attached to the fixture 2 as shown in FIG. Is done. At this time, the display surface 3 of the pedometer main body 1 is protected by the fixture 2. In the state shown in FIG. 7, when the hook button 5 for opening and closing the main body is pushed in, the hook 4 is interlocked with the hook button 5 and the pedometer main body 1 is opened.
The hook 4 and the hook engaging hole 6 are disengaged from each other, and the pedometer main body 1 can meet and see the display surface 3 from above. The display surface 3 is provided with a display unit 7, a calorie step number changeover switch 8, a reset switch 9, and the like.

FIG. 8 shows the structure of a walking sensor provided inside the pedometer main body 1. This walking sensor is of a type that detects walking using a pendulum 10 that swings by a walking motion, and the pendulum 10 is swingable about an axis 11.
The magnet 12 attached to the tip of the
The reed switch 13 is turned on and off by approaching or moving away from the reed switch 13 disposed so as to be spaced apart from and opposed to 12. The output of the reed switch 13 is output as a walking detection signal. Note that stoppers 14 and 15 are provided on both sides of the rear end of the pendulum 10, and the pendulum 10 swings between the stoppers 14 and 15. A torsion spring having one end locked between the shaft 11 and the stopper 15 and the other end locked to the pendulum 10
At 16, the swinging motion of the pendulum 10 is controlled.

By the way, in order to prevent erroneous operations due to swings due to human body movements other than walking, conventionally, methods such as making the pendulum 10 heavier to increase the moment of inertia, and providing a dead zone time by circuit processing have been adopted. However, none of them could protect against the same level of shaking as human walking.

Therefore, focusing on the fact that walking is a continuous motion, the pedometer of this embodiment determines whether or not the detection signal of the walking sensor is continuous by a circuit-like process, and determines whether the detection signal due to walking is other than the other. Is distinguished from the detection signal based on the living activity of the user.

FIG. 1 shows a basic circuit configuration of the present embodiment. The configuration and operation of the main part of this embodiment will be described after the description of the basic configuration and operation. The pedometer A of the present embodiment includes a dead zone processing circuit 22 that shapes the detection signal a output from the walking sensor 21 into one pulse per one step of walking, and a shaped pulse b output from the dead zone processing circuit 22. An operation determination circuit 24 that determines whether the detection signal of the walking sensor 21 is based on a walking operation, and an output of the dead zone processing circuit 22 after the operation determination circuit row 24 determines that the walking operation is performed. An end determination circuit 26 for determining the end of the walking motion from the actual operation timer 28 for measuring a walking time necessary for measuring a walking speed or a calorie consumption, etc .; the operation determination circuit 24;
26, an arithmetic circuit 29 for calculating the pedometer, calculating the speed, calculating the walking distance and calorie consumption according to the output of the actual operation timer 28, and a display for switching and displaying the arithmetic result of the arithmetic circuit 29 on the display unit 7. The output of the switching control circuit 30 and the dead zone processing circuit 22 is output to the operation determination circuit 24, the end determination circuit 26, and the actual operation timer 28.
Switch SW ₃ that is directly applied to the arithmetic circuit 29 without passing through
At the start of the walking operation, the output of the dead zone processing circuit 22 via the switch SW ₃ is given to the operation determining circuit 24, and when the detection signal of the walking sensor 21 is determined by the operation determining circuit 24 to be caused by walking. It is constituted by a switch SW ₁ for providing an output of the dead-zone processing circuit 22 to the end decision circuit 26. The operation determination circuit 24 repeatedly performs an operation of detecting whether or not the next output is detected within a predetermined time after one output of the dead zone processing circuit 22 is detected, and continuously performs the predetermined number of times. If detected, the walking sensor 21 at this time
Is determined to be due to the walking motion. The time for determining this walking motion is determined by timer 25.
Is set to The end determination circuit 26 determines that the walking operation has ended when the next output is not input even after the predetermined time has elapsed, and the time for the end determination is set in the timer 27. .

Hereinafter, the operation relating to the measurement of the number of steps according to the present embodiment will be described with reference to the flowchart of FIG. Incidentally, the walking action switch SW ₁ at the start operation determination circuit for performing this measurement 24
Side (e side). Pendulum 10 of walking sensor 21
Swings as shown in FIG. 3A, the walking sensor 21
Outputs the detection signal shown in FIG. This detection signal is subjected to dead zone processing by the dead zone processing circuit 22, and is shaped into one pulse for one step of walking shown in FIG. 3 (c). The output of the dead zone processing circuit 22 is connected to switches SW ₃ ,
The signal is input to the operation determination circuit 24 via the SW ₁ and is also input to the arithmetic circuit 29 via the operation determination circuit 24 at the same time. As a result, the arithmetic circuit 29 adds one value for the calculation of the number of steps, and also adds one display value as necessary. At the same time, the operation determination circuit 24 starts the timer 25 and the actual operation timer 28. Thereafter, the operation determination circuit 24 detects whether or not the output of the dead-zone processing circuit 22 follows the set time t ₁ of the timer 25 is reached. If the output of the dead-zone processing circuit 22 follows the set time t ₁ of the timer 25 has arrived, the output of the next dead-zone processing circuit 22 detects whether the incoming further set time t _1. When the output of the second dead zone processing circuit 22 arrives, the timer 25 sets the set time from the time when the output arrives.
to re-start the count of t _1. And the number of loops R
Has reached a predetermined number of times (two times in this embodiment), the motion determining circuit 24 determines that the motion is a walking motion. In the case where the output of the next dead-zone processing circuit 22 within the set time t ₁ has not arrived, together with the number corresponding to subtraction of the value and display the number of loops R calculation the number of steps of the arithmetic circuit 29, a timer 25 Then, the actual operation timer 28 is reset, and the operation determination circuit 24 returns to the initial state, and enters the standby state for the above-described operation.

When the motion determining circuit 24 determines that the walking motion is performed, the switch is performed by the control signal g of the motion determining circuit 24.
SW ₁ is switched to the end decision circuit 26 side (f side). Thereafter, the detection signal from the walking sensor 21 is output, the output of the dead-zone processing circuit 22 is inputted to the end decision circuit 26 via the switch SW _3, SW _1, at the same time end decision circuit 26
Is input to the arithmetic circuit 29. The arithmetic circuit 29 adds 1 to the count value of the number of steps each time the output of the dead zone processing circuit 22 is input, and adds 1 to the display value as needed. Also,
At the the timer is started 27 the end decision circuit 26 at the same time, the next pulse on the set time t ₂ of the timer 27 determines whether the incoming. Then, when it arrives, the operation of taking in the input of the walking sensor 21 and counting is repeated. Also,
If it has not arrived, it is determined that the walking motion has ended, an end signal j is input to the operation determining circuit 24, and the timer 27 and the actual operation timer 28 are reset. End signal j is the operation decision circuit is input 24 switches the switch SW ₁ on e side. Therefore, thereafter, the operation from the determination of the walking operation of the operation determining circuit 24 is performed.

Incidentally, the actual operation timer 28 is started when the output of the dead zone processing circuit 22 is input to the operation determination circuit 24, and measures the time until the end determination circuit 26 detects the end of walking. If the user is walking before the measurement, an integration process of adding the walking time to the previous walking time is performed. When the motion determining circuit 24 determines that the motion is not a walking motion, the motion is reset as described above. In this case, the value counted at that time is reset, and this value is not integrated. By measuring the walking time by the actual operation timer 28, the walking speed and the like are obtained. That is, the walking time, the number of steps during the walking, and the stride (a predetermined value is set).
The walking speed is calculated from. Then, the walking speed is displayed on the display unit 7.

Further, the above-described basic operation will be described with an actual example. As shown in FIGS. 3A and 3B, the walking sensor 21 outputs a detection signal by one or two swings, but after the last detection signal is output, the set time t _{1 of the} timer 25 is changed. If the detection signal is not output within the range, the motion determination circuit 24 determines that the motion is not a walking motion, and therefore, the arithmetic circuit 29 for calculating the number of steps at this time does not count. Next, as shown in FIG.
After the first and second detection signals are output, the timer 25
Set time t output next detection signal in _one of, it is determined that the walking motion by the operation decision circuit 24, one of the detection signal arrives more within the set time t ₂ of this determination after the timer 27 , then is when the next detection signal has not arrived within the set time t _2, in this case is adding four steps to the calculation value of the arithmetic circuit 29 in the previous step count.

4 and 5 are views showing the manner of display on the display unit 7. FIGS. 4 to 5 correspond to the time points 1 to 3 in FIG. 3, and FIG. FIG. 5 shows a case in which the count value is also displayed, and the display is cleared when it is determined that the user is not walking, and FIG. 5 shows that the display is not performed until the presence of the walking motion is determined. Since the number of steps at that time is added to the previous walking only when it is determined that the walking operation is performed, accurate counting of the number of steps can be performed.

Hereinafter, the calculation of the calorie consumption performed by the arithmetic circuit 29 as the gist of the present embodiment will be described. The calorie Q is approximated by the following equation.

 Q ≒ weight × step × A × number of steps (1) where A is an empirically determined constant.

In addition, the time is doing the walking motion only to the actual walking time, when the calories consumed in the day as the Q _1, walking pitch P, Becomes Here, T is the actual walking time. By the way, the consumption calories Q ₁ is, may be set by changing the calories of the goal that you want to consume properly, or because the Japanese are said to have is too much to eat 300kcal on average, in advance of this calorie fixed You may set it. further,
As the actual walking time T, the data of the previous day measured by the actual operation timer 28 or the average time per day measured for a certain period may be used.

As apparent from the above description, by setting the caloric Q ₁ and walking time T to be consumed before starting the walking, walking pitch P to burn calories Q ₁ to be consumed during exercise it is seen. Therefore, the target calorie setting unit 37 in the present embodiment to set the target calories Q _1, body weight, provided a stride setting unit 38, in the above setting unit 37 before starting the walking, as shown in Figure 2 to set the target calories Q _1. In addition, since the weight and the stride are set at the start of use or the like, the setting is performed only when a change occurs, for example. In this embodiment, the measured time measured the day before by the actual operation timer 28 is used as the actual walking time T. The arithmetic circuit 29 calculates the walking pitch P based on these set values. Therefore, after walking is started and after the movement determination circuit 24 determines that it is a walking movement,
As shown in FIG. 4 (b), a pitch sound is emitted from the pitch sound generating section 42 at the output of the arithmetic circuit 29. In this embodiment, since the measured value of the actual operation timer 28 of the previous day is used as the actual walking time T, the arithmetic circuit 29 stores the integrated value of the measured time of the actual operation timer 28 as the actual walking time T of the previous day. There is a need to. Therefore, the end time setting unit 39 for setting the end time
A clock 41 provided with
From 28, the measured time accumulated in the arithmetic circuit 29 is input. Thus, the actual operation timer 28, the end time setting unit 39, and the clock 41
Thus, an actual walking time setting means for setting the actual walking time T is configured. The time 41 can be set by the time setting unit 40. As described above, according to the present embodiment, since the pitch sound indicating the pace of walking is emitted, if the user walks in accordance with the pitch sound, calories he / she wants to consume can be consumed more reliably than a conventional pedometer.
In the above description, the walking sensor 21 having the structure shown in FIG. 8 is used. However, any other walking sensor such as a pressure sensor provided on the sole of the shoe can be used as long as a detection signal can be obtained with walking. It may be.

Incidentally, in this pedometer are external handler 23 is provided for operating the switch SW ₃ as shown in Figure 1. The external operator 23 switches the switch SW ₃ from the normal c side to the d side. When the external operator 23 switches the switch SW ₃ to the d side, the operation determining circuit 24 and the end determining circuit
The output b of the dead band processing circuit 22 is an arithmetic circuit without passing through 26 etc.
It is provided to 29 and the walking is counted without determining the walking motion and the end of walking. In other words, in the case of use under irregular motions such as aerobics and jazz dance, the determination of the walking motion and the determination of the end of the walking cannot be performed with high accuracy. This is for counting.

Further, this pedometer has the following configuration. That is, a switch SW ₂ for detecting the opening and closing of the pedometer main body 1,
A light-emitting unit that emits light through the display switching control circuit when the pedometer main body is opened, and illuminates the display unit with the light-emitting unit when the pedometer main body is opened so that the display unit is easy to see. It is made to become. In addition, since the pedometer main body 1 is provided with the lighting mechanism, if the pedometer main body 1 is forgotten to be closed or the lock of the pedometer main body 1 is unlocked for some reason, the pedometer main body 1 is left open and the battery is wasted. There are problems such as consumption. Therefore, a notification timer 35 is provided, and when the pedometer main body 1 is left open for a predetermined time or more, an alarm is issued from the notification unit 36. In addition to the alarm as described above, a driving means for automatically closing the pedometer main body 1 may be provided in the case where the pedometer main body 1 is left open for a predetermined time or more, or the pedometer main body 1 is always biased in the closing direction. A biasing means may be provided to automatically close when the hand is released.
