Description

  The present invention relates to an electronic apparatus having a function of measuring a pitch of a periodic signal such as a walking signal that is periodically generated.

Conventionally, electronic devices that measure walking (including running) pitch (the number of steps per unit time) have been developed (see, for example, Patent Documents 1 and 2).
These electronic devices have step count detection means, and are configured to calculate the number of steps per unit time based on the number of steps detected in a predetermined section and the section time and display it as a pitch. In particular, the pitch is often displayed in terms of the number of steps per minute “steps / minute”.
For electronic devices with a step detection function, it is usually desirable to always detect the number of steps during measurement. However, as a total product including other functions, the number of steps is temporarily detected in various situations. There are many situations that must be prohibited.

For example, when a sound reporting function is added to a product, if the sound reporting function is activated during the step count detection operation, noise is generated by the sound reporting, and the gait sensor does not walk (or run) even though it is not walking. There is a problem in that it is erroneously detected as walking in response to, and the number of steps is erroneously counted.
In addition, when the battery is driven, there is a problem that if the load temporarily increases and a large current flows, the power supply voltage decreases and normal step count measurement may not be performed. .
Under these circumstances, an operation such as temporarily prohibiting the step detection operation is performed.

12 and 13 are flowcharts showing the processing of the conventional pedometer.
In FIG. 12 and FIG. 13, when the measurement of the section time, which is the time for measuring the pitch, is started by operating the input unit (step S121), the step counting operation is not prohibited (step S122), and the walking signal Is detected (step S123), one step is added to the number of steps measured so far, and the current cumulative number of steps is counted (step S124). After performing the step counting operation during the section time, the step counting operation is ended by operating the input unit (step S125), and the section step and the section step number detected in the section time are stored in the storage unit. Then, the step counting operation is finished (steps S126 and S127).
When calculating the pitch from the measurement result such as the number of steps, the section time and the number of section steps stored in the storage unit are read (steps S131 and S132), and the average step pitch (section pitch) is calculated by dividing the section step count by the section time. ) Is calculated (step S133), and the section pitch is displayed on the display unit (step S134).

When calculating the section pitch as described above, if there is a time during which the step count detection operation is temporarily prohibited within the section time, the number of steps is reduced by the amount of the step count prohibition. There is a problem that the calculated pitch becomes small.
As a method for solving the above problem, it is conceivable to use the invention described in Patent Document 3 to correct the number of steps for the number of steps detection prohibition time based on the immediately preceding pitch. In this case, the section time, which is the unit time for measuring the pitch, can be measured correctly, but when the actual pitch fluctuates during the step detection prohibition section (for example, when the running is stopped). Has a problem that it is difficult to calculate a correct pitch.
Further, not only the pedometer, but also an electronic device having a pitch measurement function of a periodic signal generated periodically, such as a heart rate monitor or a pulse meter, has the same problem as described above.

FIG. 5 is a flowchart showing processing of the pedometer according to the first embodiment of the present invention, and is a flowchart showing an example of canceling prohibition of step count measurement operation measurement.
4 and 5 are processes common to the embodiments described later.

Hereinafter, the operation of the first exemplary embodiment of the present invention will be described in detail with reference to FIGS.
The user starts the measurement of the section time, which is the time to measure the walking pitch, by operating the input unit 106, and at the same time, walks with the pedometer attached to the body or stored in a portable bag or the like Start.
In response to the interval time measurement start instruction from the input unit 106, the CPU 105 starts the interval time counting operation based on the signal from the oscillation unit 109 (step S201).
The CPU 105 determines whether or not the step counting operation is prohibited (step S202), and when the step counting operation is not prohibited, the time during which the step counting operation is performed based on the signal from the oscillation unit 109. Measurement processing of (section step count operation valid time; time obtained by subtracting step count measurement operation prohibition time (section step count measurement prohibition time) from section time) is performed (step S203).

Here, an example of the step count prohibition operation will be described with reference to FIG. The example of prohibiting the step counting operation shown in FIG. 4 is an example in which, when an alarm is sounded at a set time, it is possible to prevent a step counting error from occurring due to noise generated when the alarm is sounded.
In FIG. 4, the CPU 105 performs a time counting operation for the current time based on a signal from the oscillation unit 109. When the alarm set time matches the current time (step S401), the step counting operation is set to be prohibited. (Step S402), an alarm is sounded from the sound report unit 108 (Step S403). Thereby, the step count measurement error which occurs when the alarm is sounded can be suppressed.

FIG. 5 shows an example in which the step count prohibition operation is canceled. In this example, the step count prohibition operation is canceled after the step count prohibition operation is prohibited by an alarm.
In FIG. 5, after the sound reporting unit 108 starts alarm reporting, the CPU 105 determines whether or not an alarm reporting end condition is satisfied (step S501). Examples of the alarm sounding end condition include a case where an alarm ringing stop operation is performed by the input unit 106 or a case where the alarm sound end time is reached.
If the CPU 105 determines in step S501 that the alarm reporting end condition is satisfied, the CPU 105 ends the alarm reporting operation of the reporting unit 108 (step S502), and then cancels the prohibition of the step counting operation (step S503). ). As a result, the CPU 105 can perform a step counting operation. The time from the gait measurement operation prohibition process in process step S402 to the gait measurement operation prohibition release process in process step S503 is the interval step count measurement operation prohibition time.

As described above, the CPU 105 measures the section time in response to the section time measurement start instruction from the input unit 106, and at the same time, measures the section step count operation effective time.
The acceleration sensor 101 detects walking and outputs a walking signal corresponding to each walking. The walking signal is input to the CPU 105 as a walking signal in the form of a digital signal through the filter unit 102, the amplification unit 103, and the binarization unit 104.

  If the CPU 105 determines that the walking signal from the acceleration sensor 101 has been input via the binarization unit 104 or the like (step S204), the CPU 105 adds one step to the cumulative number of steps so far and counts the current cumulative number of steps (step S204). S205). During the interval time, after performing the step count operation of processing steps S202 to S205, the interval time measurement operation is ended by the user operating the input unit 106. In response to the measurement time end operation of the input unit 106, the CPU 105 ends the section time measurement operation and ends the step counting operation (step S206), and then the section time (from the step count operation start instruction by the input unit 106, the number of steps). The time until the measurement operation end instruction) and the number of steps detected in the section time (section step count) are stored in the storage unit 110 (step S207), and the section step count measurement operation effective time in the section time is stored in the storage unit 110. Then, the step counting operation is finished (step S208). The section step count operation valid time corresponds to the section valid time which is the time during which the number of steps can be measured during the section time.

  When calculating the average walking pitch in the section time from the measurement result such as the number of steps, in FIG. 3, the CPU 105 reads out the section step count measurement operation effective time in the section time and the section step count in the section time stored in the storage unit 110. (Steps S301 and S302), the average walking pitch (section pitch) in the section time is calculated by dividing the section step count by the section step count measurement effective time (step S303), and the section pitch is displayed on the display unit 107. (Step S304).

As described above, in the pedometer according to the first embodiment, the acceleration sensor 101 outputs a walking signal corresponding to walking to the CPU 105 via the filter unit 102, the amplification unit 103, and the binarization unit 104. To do. The storage unit 110 stores information on the effective time in the section, which is the measurement time of the measurement section time, and the number of steps. The CPU 105 performs a pedometer time operation, obtains information on the effective time within the section in which the number of steps can be measured within the section time for measuring the pitch, stores the information in the storage unit 110, and the section based on the walking signal detected by the acceleration sensor 105 The number of steps in time is counted and stored in the storage unit 110. The CPU 105 is configured to calculate the walking pitch of the section time based on the information regarding the effective time within the section stored in the storage unit 110 and the number of steps in the section time.
Therefore, even when a time in which the number of steps cannot be measured in the section time occurs, it is possible to obtain a more accurate pitch.

FIG. 6 is a flowchart showing the process of the pedometer according to the second embodiment of the present invention, and is a flowchart showing the step count measurement process.
FIG. 7 is a flowchart showing the processing of the pedometer according to the second embodiment of the present invention, and is a flowchart showing the pitch calculation processing.
In the second embodiment, the circuit block diagram, the step count operation prohibition process, and the step count operation prohibition release process are the same as those in FIGS. 1, 4, and 5, respectively.

In the following, the operation of the second embodiment will be described with reference to FIGS. 1 and 4 to 7 mainly for the parts different from the first embodiment.
In response to the interval time measurement start instruction from the input unit 106, the CPU 105 starts the interval time counting operation based on the signal from the oscillation unit 109 (step S201).
The CPU 105 determines whether or not the step counting operation is prohibited (step S202). If the step counting operation is not prohibited, the CPU 105 receives a walking signal from the acceleration sensor 101 via the binarization unit 104 or the like. If it is determined that it has been input (step S204), one step is added to the cumulative number of steps so far, and the current cumulative number of steps is counted (step S205).

When the CPU 105 determines in step S202 that the step counting operation is prohibited during the section time, the CPU 105 measures and processes the section step counting operation prohibiting time, which is the time during which the step counting operation is prohibited during the section time. The process proceeds to step S206 (step S601).
Further, the CPU 105 stores the section step count in the storage unit 110 in the processing step S208, and then stores the cumulative section step count operation prohibition time measured in the section time in the storage unit 110 (step S602). The interval step count operation prohibition time is an ineffective interval within the interval in which the step count measurement operation is prohibited. The section time and the ineffective time within the section are stored in the storage unit 110 as information regarding the effective time within the section.
As described above, the CPU 105 measures the section time in response to the section time measurement start instruction from the input unit 106 and, at the same time, measures the section step count measurement prohibition time.

When calculating the average walking pitch in the section time from the measurement results such as the number of steps, in FIG. 7, the CPU 105 prohibits the section time stored in the storage unit 110, the section step count in the section time, and the section step count measurement operation in the section time. The time is read (steps S701 to S703).
Next, the CPU 105 calculates the section step count measurement operation effective time by subtracting the section step count measurement prohibition time from the section time (step S704), and divides the section step by the section step count measurement operation valid time to thereby calculate the section time. The average walking pitch (section pitch) is calculated (step S705), and the section pitch is displayed on the display unit 107 (step S706).

As described above, in the electronic apparatus having the pitch measurement function according to the second embodiment, as in the case of the first embodiment, even when there is a time in which the step count cannot be measured in the section time, it is more accurate. It becomes possible to obtain a pitch.
In the first embodiment, the storage unit 110 is configured to store the section step count operation valid time. However, in the second embodiment, the section step count operation valid time is used instead of the section step count operation valid time. The section step count prohibition time, which is the ineffective time, is stored. In general, since the section step count operation prohibition time is shorter than the section step count operation valid time, the amount of data stored in the storage unit 110 can be reduced.

FIG. 8 is a flowchart showing the process of the pedometer according to the third embodiment of the present invention, and is a flowchart showing the step count measurement process.
FIG. 9 is a flowchart showing the processing of the pedometer according to the third embodiment of the present invention, and is a flowchart showing the pitch calculation processing.
In the third embodiment, the circuit block diagram, the step count operation prohibition process, and the step count operation prohibition release process are the same as those in FIGS. 1, 4, and 5, respectively.

Hereinafter, with reference to FIGS. 1, 4, 5, 8, and 9, the operation of the third embodiment will be described mainly with respect to the differences from the first embodiment.
The CPU 105 stores the section step count in the section time in the storage unit 110 (step S208), and then stores the time ratio of the section step count measurement operation effective time in the section time (section step count measurement operation effective time ratio) in the storage unit 110. Then, the step counting operation is finished (step S801). The section time and the section step count measurement effective time ratio are stored in the storage unit 110 as information related to the intra-section effective time.

When calculating the average walking pitch in the section time from the measurement result such as the number of steps, in FIG. 9, the CPU 105 enables the section time stored in the storage unit 110, the section step count in the section time, and the section step count measurement operation in the section time. The time ratio is read (steps S901 to S903).
Next, the CPU 105 corrects the section time based on the section step count operation valid time ratio and effectively performs the step count operation (corrected section time, which corresponds to the section step count operation valid time). Is calculated (step S904).
Next, the CPU 105 calculates the average walking pitch (section pitch) in the section time by dividing the section step count by the correction section time (step S905), and causes the display section 107 to display the section pitch (step S906). .

As described above, even in the electronic apparatus having the pitch measurement function according to the third embodiment, as in the first embodiment, even when a time in which the step count cannot be measured in the section time occurs, it is more accurate. It becomes possible to obtain a pitch.
In the first embodiment, the storage unit 110 is configured to store the section step count operation valid time. However, in the third embodiment, the section step count operation valid time is used instead of the section step count operation valid time. It is configured to store the step count operation effective time ratio. Thus, by converting to a ratio and storing it, it is possible to reduce the amount of memory required for storage as compared with the case of directly storing the section step count operation effective time. For example, if the maximum measurement time is 24 hours and the resolution is 1/100 second, data is required up to 23 hours 59 minutes 59 seconds 99 as the section step count measurement effective time, but if converted to a rate of 1% resolution 0 to 100 is sufficient.

FIG. 11 is a flowchart showing processing of the pedometer according to the fourth embodiment of the present invention, and is a flowchart showing pitch calculation processing.
In the fourth embodiment, the circuit block diagram, the step count operation prohibition process, and the step count operation prohibition release process are the same as those in FIGS. 1, 4, and 5, respectively.

Hereinafter, with reference to FIGS. 1, 4, 5, 10, and 11, the operation of the fourth embodiment will be described mainly with respect to the differences from the second and third embodiments.
The CPU 105 stores the section step count in the section time in the storage unit 110 (step S208), and then stores the time ratio of the section step count measurement operation prohibition time in the section time (section step count measurement operation invalid time ratio) in the storage unit 110. Then, the step counting operation is finished (step S1001). The section time and the section step count measurement operation ineffective time ratio are stored in the storage unit 110 as information on the in-section effective time.

When calculating the average walking pitch in the section time from the measurement result such as the number of steps, in FIG. 11, the CPU 105 stores the section time stored in the storage unit 110, the section step count in the section time, and the section step count measurement operation in the section time. The effective time ratio is read (steps S901, S902, S1101).
Next, the CPU 105 corrects the section time based on the section step count operation ineffective time ratio and makes the step count operation effective (the corrected section time, from the section time to the section step count operation ineffective time ratio). Is calculated by subtracting the corresponding time) (step S1102).
Next, the CPU 105 calculates the average walking pitch (section pitch) in the section time by dividing the section step count by the correction section time (step S905), and causes the display section 107 to display the section pitch (step S906). .

As described above, in the electronic apparatus having the pitch measurement function according to the fourth embodiment, as in the case of the third embodiment, even when there is a time in which the step count cannot be measured in the section time, it is more accurate. It becomes possible to obtain the pitch, and it is possible to reduce the amount of memory required for storage by storing the interval step count measurement operation invalid time ratio.
