JP 2001-203783 A (FIG. 1)

  However, in the case of the technique of Patent Document 1, since the CPU performs a counting operation, the CPU is always in an operating state during walking. For this reason, there is a problem that the processing load on the CPU is large and a problem that the power consumption of the CPU is large.

  Further, when the step counting device is mounted on a mobile phone, there is a problem that the sustainability of the battery is deteriorated when the CPU is always operated and the power consumption is large as in Patent Document 1.

  The present invention has been made to solve the above-described problems, and an operation frequency counting apparatus and method capable of operating with low power consumption (specifically, for example, a step counting apparatus and method). The purpose is to provide.

  In order to solve the above-described problem, the operation counting device of the present invention counts the number of detection signals output from the operation detection unit that outputs a detection signal each time an operation to be counted is detected, and the operation detection unit. It is characterized by comprising an operation number counter and control means capable of acquiring the count value of the operation number counter and recognizing the count value.

  According to the operation number counting device of the present invention, the counting operation can be performed by the cooperation of the operation detecting unit and the operation number counter. Therefore, it is not necessary to perform the counting operation by the control means such as a CPU. The control means need only acquire the count value of the operation number counter only when it is desired to recognize the above. Therefore, it is possible to prevent the control means from being always in an operating state during a period in which an operation (for example, walking) that is subject to frequency counting is performed. As a result, it is possible to suppress the power consumption of the control means, and hence the entire operation counting device. Therefore, for example, even when the operation count device is mounted on a mobile communication terminal device such as a mobile phone, the sustainability of the battery of the mobile communication terminal device is not deteriorated.

  The acquisition (and recognition) by the control means of the count value of the operation number counter can be performed according to the user's operation, for example. Alternatively, for example, it can be performed at preset time intervals. May be.

  In addition, the operation detection unit can be provided in the integrated circuit, and the operation frequency counter can be configured by a simple logic circuit. For this reason, it is preferable that the operation number counter and the operation detection unit are integrated in the same integrated circuit.

  In the operation number counting device of the present invention, a second operation number counter that counts the number of detection signals output from the operation detection unit, an operation number setting register that can set an arbitrary operation number, and the operation number A comparator that compares a set value of the setting register with a count value of the second operation number counter and outputs a coincidence signal when both values coincide with each other; and the second operation number counter Each time the coincidence signal is received from the comparator, the count value of the second operation number counter is reset, while the control means receives the coincidence signal every time it receives a coincidence signal from the comparator. It is preferable to calculate a product of the number of times and the set value of the operation number setting register as an approximate number of the number of operations to be counted.

  In this case, by setting an arbitrary value in the operation count setting register, it is possible to arbitrarily set the calculation processing interval (processing interval for calculating the approximate number of operation counts) by the control means. Therefore, the operation number is automatically calculated every arbitrary operation number (for example, every 100 times or every 1000 times) without performing the operation of acquiring the count value for the operation number counter from the control means. The result can be recognized as an approximate number of operations.

  Alternatively, in the operation number counting device of the present invention, a second operation number counter that counts the number of detection signals output from the operation detection unit, an operation number setting register that can set an arbitrary operation number, A comparator that compares the set value of the operation count setting register with the count value of the second operation count counter and outputs a match signal when both values match, the second operation The number counter resets the count value of the second operation number counter every time a coincidence signal is received from the comparator, while the control means performs the operation number of times each time a coincidence signal is received from the comparator. It is also preferable to acquire the count value of the counter and recognize the count value as an approximate number of times of the operation to be counted.

  In this case, by setting an arbitrary value in the operation number setting register, it is possible to arbitrarily set the interval for acquiring the count value of the operation number counter by the control means. Therefore, for example, even if the user does not perform a count value acquisition operation, the number of operations is automatically acquired every arbitrary number of operations (for example, every 100 times, every 1000 times, etc.), and the acquired result is operated. It can be recognized as an approximate number of times.

  Further, the operation detection unit can be provided in the integrated circuit, and the second operation number counter, the operation number setting register, and the comparator can be configured by simple logic circuits. Therefore, it is preferable that the operation detection unit, the operation number counter, the second operation number counter, the operation number setting register, and the comparator are integrated in the same integrated circuit.

  In the operation number counting device of the present invention, it is preferable that the control means sets a setting value for the operation number setting register.

  In the operation frequency counting device of the present invention, it is preferable that the control means includes, for example, a CPU.

  In the motion number counting device of the present invention, the motion detection unit includes an acceleration detection unit that detects acceleration, and whether the acceleration detected by the acceleration detection unit is an acceleration that should be determined that the operation to be counted has occurred. It is preferable to include an acceleration determination unit that determines whether or not and a detection signal output unit that outputs the detection signal each time the acceleration determination unit determines that the operation has occurred.

  The operation count device of the present invention is preferably a step count device that counts the number of steps, for example. In this case, the motion detection unit outputs the detection signal every time it detects walking as the motion to be counted.

  A mobile communication terminal device (for example, a mobile phone) according to the present invention includes the operation frequency counting device according to the present invention.

  In addition, the operation number counting method of the present invention includes a detection signal output step of detecting the operation to be counted and outputting a detection signal, an operation number counting step of counting the number of the detection signals by an operation number counter, and the operation And a count value obtaining step in which the control means obtains the count value obtained by the number counter.

  In the operation number counting method of the present invention, a second operation number counting step for counting the number of the detection signals by a second operation number counter, and an operation number setting step for setting an arbitrary operation number in the operation number setting register. A match signal output step of comparing the set value of the operation count setting register with the count value of the second operation count counter and outputting a match signal when both values match, and the second Each time the operation number counter receives a coincidence signal from the comparator, a reset step of resetting the count value of the second operation number counter, and whenever the control means receives a coincidence signal from the comparator, Approximate calculation for calculating the product of the number of times of reception of the coincidence signal and the set value of the operation count setting register as an approximate number of the operations to be counted. Preferably further comprising the steps, a.

  Alternatively, in the operation number counting method of the present invention, a second operation number counting step for counting the number of the detection signals by a second operation number counter, and an operation number for setting an arbitrary operation number in the operation number setting register. A matching signal output step of comparing a setting step, a set value of the operation count setting register and a count value by the second operation count counter, and outputting a match signal when both values match; Each time the second operation number counter receives a coincidence signal from the comparator, a reset step for resetting the count value of the second operation number counter, and each time the control means receives a coincidence signal from the comparator. In addition, the count value of the operation number counter is acquired, and the count value is recognized as an approximate number of the number of operations to be counted. It is also preferably further comprises a step.

  For example, the operation count method of the present invention is preferably a step count method that counts the number of steps. In this case, in the signal output step, the detection signal is output every time the walking as the operation to be counted is detected.

  According to the present invention, the count operation can be performed by the cooperation of the operation detection unit and the operation frequency counter. Therefore, the control unit including the CPU does not need a program for the count operation and needs to perform the count operation. There is no. Therefore, it is possible to prevent the control means from being always in an operating state during a period of performing an operation (for example, walking, etc.) that is the object of counting the number of times, and the processing load on the control means is reduced. That is, for example, only when the user wants to recognize the count value of the operation, the control unit can perform the operation of acquiring the count value of the operation counter and can recognize the count value. Therefore, it is not necessary to constantly monitor the operation detection unit, and the operation time of the control means is short. As a result, the power consumption of the control means, and thus the entire operation counting device, can be suppressed. Therefore, for example, even when the operation count device is mounted on a mobile communication terminal device such as a mobile phone, the sustainability of the battery of the mobile communication terminal device is not deteriorated.

  Embodiments according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a step count device (operation count device) 100 according to an embodiment of the present invention.

  As shown in FIG. 1, the step counting device 100 according to the present embodiment includes a walking detection unit (motion detection unit) 10 that detects walking, a total step number reading counter (operation number counter) 13 that counts all steps, CPU 20 capable of acquiring the count value of the total number of steps read counter 13, ROM 21 storing a control program of the CPU 20, RAM 22 functioning as a work area of the CPU 20, and the arithmetic processing interval of the approximate number of steps by the CPU 20 A step number setting register (operation number setting register) 12 in which an arbitrary number of steps is set, a step number counter (second operation number counter) 11 that is reset for each step number set in the step number setting register 12, and a step number counter 11 Comparator 14 that performs a comparison operation between the count value and the setting value of step count setting register 12 , A notification unit 23 for notifying operation of the step count (count value), and is configured to include an operation unit 24 for a user performs an operation of step count unit 100, a. In the above, the control unit (control means) 30 is configured by the CPU 20, the ROM 21 and the RAM 22.

  The walking detection unit 10 outputs an interrupt signal (detection signal) to the total number of steps reading counter 13 and the number of steps counter 11 every time one step of the user of the step counting device 100 is detected.

  Specifically, the walking detection unit 10 is, for example, an acceleration detection unit 10a that detects acceleration, and whether or not the acceleration detected by the acceleration sensor unit 10a is a value that should be determined as walking. And an interrupt signal output unit (detection signal) that outputs an interrupt signal to the total step number reading counter 13 and the step number counter 11 each time it is determined that walking has been performed by the acceleration determination unit 10b. Output section) 10c.

  Here, for example, the acceleration detection unit 10a is configured to be able to detect acceleration in a total of two axial directions that are included in a plane and are orthogonal to each other in the X-axis direction and the Y-axis direction. It is configured to be able to detect acceleration in a total of three axial directions including the axial direction and the Z-axis direction that is a direction orthogonal to the two axial directions (that is, the vertical direction).

  In addition, the acceleration determination unit 10b, for example, acceleration in each axial direction (for example, a total of two axial directions of the X axis direction and the Y axis direction, or a total of three axial directions of the X axis direction, the Y axis direction, and the Z axis direction). When each exceeds the reference value, it is determined that walking has been performed. Or you may make it the acceleration determination part 10b determine whether the walk was performed by also considering the relative relationship of the acceleration in each axial direction, for example.

  The total number of steps reading counter 13 counts up the number of steps of the user every time an interrupt signal is input from the walking detector 10.

  Here, for example, the CPU 20 performs read access to the total number of steps read counter 13 according to an operation on the operation unit 24, and obtains a count value of the total number of steps read counter 13, that is, a value indicating the total number of steps of the user. To get.

  Further, when the CPU 20 recognizes the acquired count value, for example, the CPU 20 performs control to cause the notification unit 23 to notify the count value.

  The notification unit 23 includes, for example, at least one of a display device and a speaker, and notifies the count value acquired by the CPU 20 by at least one of display and pronunciation. Thereby, the user can know the count value, that is, the total number of steps of the user.

  Note that an inverter 16 for inverting the request signal is inserted in series in a signal line 25 for transmitting a request signal for requesting a count value from the CPU 20 to the total step number reading counter 13. The total step count reading counter 13 outputs the count value of the total step count reading counter 13 to the CPU 20 at the timing when the input signal from the inverter 16 switches from high to low.

  Also, the step counter 11 counts up the number of steps of the user each time an interrupt signal is input from the walking detector 10, as with the total step number reading counter 13.

  Further, the CPU 20 sets an arbitrary value in the step count setting register 12 in advance in order to determine the execution interval of the process for calculating the approximate number of steps. Here, the setting processing of the setting value of the step count setting register 12 by the CPU 20 is performed according to an operation on the operation unit 24, for example. That is, the user can set a desired number of steps in the step count setting register 12 by operating the operation unit 24.

  The comparator 14 performs a comparison operation between the value set in the step count setting register 12 and the count value by the step count counter 11, and each time both values match, a match signal is sent to the step count counter 11 and the CPU 20. Output.

  Each time the coincidence signal from the comparator 14 is input, the CPU 20 multiplies the set value of the step count setting register 12 and the number of coincidence signals input from the comparator 14 so far by the user's time point. Recognized as an approximate number of steps in The CPU 20 counts up the number of coincidence signals input from the comparator 14. That is, the RAM 22 has a storage area for storing and holding the number of coincidence signals input from the comparator 14 to the CPU 20. Each time the coincidence signal is input from the comparator 14, the CPU 20 updates the contents of the storage area to count the number of coincidence signals input, and the value thus counted and the setting of the step count setting register 12. By multiplying the value, it is possible to calculate the approximate number of steps of the user at that time.

  In addition, when the CPU 20 recognizes the approximate number of steps, the CPU 20 performs control so that the notification unit 23 notifies the approximate number.

  In short, each time the user walks the number of steps set in the step number setting register 12, the CPU 20 calculates the approximate number of steps, and the calculation result is notified by the notification unit 23. Therefore, the user always calculates the approximate number of steps. Can walk while recognizing.

  In addition, when the coincidence signal from the comparator 14 is input, the step counter 11 resets the count value of the step counter 11 to “0”.

  Note that the count values of the step count counter 11 and the total step count reading counter 13 are reset by the CPU 20 to “0” even when the user operates the operation unit 24. That is, when a reset operation is performed on the operation unit 24, a counter reset signal is output from the CPU 20 to the step count counter 11 and the total step count reading counter 13, and the count values of both the counters 11 and 13 are reset.

  Here, the counter reset signal output from the CPU 20 to the step count counter 11 and the coincidence signal output from the comparator 14 to the step count counter 11 are input to the NOR circuit 15 and output from the NOR circuit 15. A signal is input to the step counter 11. The step count counter 11 resets the count value of the step count counter 11 at the timing when the output signal from the NOR circuit 15 switches from high to low. That is, the step count counter 11 is reset at a timing when at least one of the coincidence signal from the comparator 14 and the counter reset signal from the CPU 20 is output.

  In addition, among the above components, the walking detection unit 10 can be provided in, for example, an integrated circuit (IC: Integrated Circuit). Further, the step count counter 11, the step count setting register 12, the total step count reading counter 13, the comparator 14, the NOR circuit 15 and the inverter 16 can be configured by simple logic circuits. Therefore, it is preferable that the walking detection unit 10, the step count counter 11, the step count setting register 12, the total step count reading counter 13, the comparator 14, the NOR circuit 15 and the inverter 16 are all integrated in the same IC.

  The step count device 100 is configured as described above.

  Note that the step counting device 100 according to the present embodiment is preferably mounted on, for example, a mobile phone or other mobile communication terminal device. In this case, the CPU 20, the ROM 21, and the RAM 22 are, for example, the CPU, the ROM, and the RAM that are originally provided in the mobile communication terminal device. Similarly, the notification unit 23 is the display device that is provided in the mobile terminal device (for example, a liquid crystal display). Display device) or a speaker.

  Next, the operation will be described.

  2 and 3 are flowcharts showing the flow of the step counting operation by the step counting device 100 of FIG. 1, in which FIG. 2 shows the first half and FIG. 3 shows the second half.

  First, the user performs an operation for setting a desired set value on the operation unit 24 in order to determine an interval for calculating the approximate number of steps. When receiving this operation, the CPU 20 sets a set value in the step count setting register 12. Specifically, for example, if it is desired to know the number of steps at that time every 100 steps, an operation of setting “100” as a set value to the step number setting register 12 may be performed (step S1).

  Next, the user performs an operation for starting the step counting operation by the step counting device 100 (step S2). That is, for example, when the step count device 100 is mounted on a mobile phone, the step count function is selected from the menu screen of the mobile phone and set to ON. Then, the walking detection unit 10 is activated, and each time one step of the walking of the user carrying the step count device 100 is detected, the walking detection unit 10 shifts to an interrupt signal output state (step S2).

  Therefore, every time an interrupt signal is output from the walking detection unit 10, the step count counter 11 and the total step count reading counter 13 each count up the count value (step S3).

  The comparator 14 compares the value set in the step count setting register 12 with the count value by the step count counter 11 (step S4).

  If the two values match according to this comparison (Yes in step S5), a coincidence signal is output from the comparator 14 to the CPU 20 and the step count counter 11 (via the NOR circuit 15) (step S6). .

  When the coincidence signal is output, the step count counter 11 resets the value and returns to “0” (step S7).

  The CPU 20 takes in the coincidence signal as an interrupt signal, and calculates the product of the number of coincidence signals input to the CPU 20 so far and the set value of the step count setting register 12 (step S8). Based on the calculation result, the CPU 20 recognizes the approximate number of steps so far, and performs control for causing the notification unit 23 to notify the recognized number of steps, for example. That is, every time the set number of steps is walked, the approximate number of steps reported by the notification unit 23 is updated. Therefore, the user can always know the approximate number of steps so far by confirming this notification.

  On the other hand, if the two values do not match due to the comparison by the comparator 14 (No in step S5), the step count counter 11 continues counting (repeats the processing after step S3).

  The step counter 11 continues to count as the user walks thereafter, and resets by a coincidence signal that is output every time the comparator 14 matches as a result of comparison, and returns to “0”.

  Similarly, the total number of steps reading counter 13 continues counting with the user's walking thereafter.

  When the user performs an operation for confirming the accurate total number of steps at a certain time (Yes in step S9), the CPU 20 performs read access to the total number of steps read counter 13, and the count value, that is, the accurate Information on the total number of steps is acquired (step S10). Based on the acquired information, the CPU 20 performs control to notify the total number of steps at that time by the notification unit 23 (step S11). Thus, the user can know the exact total number of steps at that time.

  Thereafter, the step count counter 11 and the total step count readout counter 13 continue counting as the user walks (step S12).

  When the user performs an operation (reset operation) for resetting the count value of the number of steps (Yes in step S13), the step count counter 11 and the total step count reading counter 13 reset the respective count values to “0”. (Step S14), and then prepare for a new counting operation (operation after Step S3). Here, when a reset operation is performed, the CPU 20 also resets the storage area of the RAM 22 that stores the number of coincidence signals input from the comparator 14 to the CPU 20 (the count value of the coincidence signal is also reset).

  On the other hand, when the reset operation by the user is not performed, the step count counter 11 and the total step count read counter 13 continue counting with the user walking (step S15).

  In addition, when the user performs an operation to end the step counting operation by the step counting device 100 (Yes in step S16), the step counting operation is stopped. That is, the walking detection unit 10 stops and does not detect the user's walking. Therefore, even if the user who walks with the step count device 100 walks, the step count counter 11 and the total step count read counter 13 do not count up, and the respective count values are held as they are (step S17). ).

  Thereafter, when the user turns on the step count function again (step S2), the step count counter 11 and the total step count read counter 13 restart counting from the held count values (operations after step S3).

  On the other hand, when the user does not perform an operation of ending the step counting operation by the step counting device 100 (No in step S16), the step counter 11 and the total step reading counter 13 continue to count as the user walks. Continue (step S18).

  According to the embodiment as described above, the walk detection unit 10 that outputs an interrupt signal every time one walk is detected, and the total step number reading counter 13 that counts the number of input interrupt signals from the walk detection unit 10; Therefore, the step counting operation can be performed in cooperation with the walking detector 10 and the total step reading counter 13. Therefore, the ROM 21 of the control unit 30 does not need to be provided with a count operation program, and the control unit 30 does not need to perform a count operation, so that the processing load on the control unit 30 can be suppressed. That is, only when the user wants to recognize the count value of the number of steps, the operation unit 24 is operated, and the CPU 20 performs the operation of acquiring the count value of the total number of steps read counter 13 so that the count value can be recognized. The CPU 20 does not need to constantly monitor the walking detector 10 for counting the number of steps, and the operation time of the CPU 20 is short. Therefore, it can prevent that CPU20 of the control part 30 will always be in an operation state during the period when a user walks. As a result, it is possible to suppress power consumption of the control unit 30, and by extension, the total number of steps counting device 100. Therefore, even when the step count device 100 is mounted on a mobile communication terminal device such as a mobile phone, the battery sustainability of the mobile communication terminal device is not deteriorated.

  In addition to the total number of steps read counter 13, a step number counter 11 that counts the number of interrupt signals input from the walking detection unit 10, a step number setting register 12 in which an arbitrary set value is set, and a setting of the step number setting register 12 are set. A comparator 14 that outputs a coincidence signal when a coincidence is detected by a comparison operation between the value and the count value of the step counter 11, and the CPU 20 receives the coincidence signal from the comparator 14 every time the coincidence signal is received. Is calculated as an approximate number of all the steps, so by setting an arbitrary value in the step setting register 12, an arithmetic processing interval (calculation processing of the approximate number of steps) is performed by the CPU 20. The number of steps for determining the interval) can be arbitrarily set. Therefore, the number of steps is automatically calculated at every arbitrary number of steps (for example, every 100 steps or every 1000 steps, for example) without performing the count value acquisition operation for the total number of steps read counter 13 from the CPU 20, and the calculation result Can be recognized as an approximate number.

  Further, the walk detection unit 10 is provided in the IC, and the circuit configuration is simplified by providing the step count counter 11, the step count setting register 12, the total step count reading counter 13, the comparator 14, the NOR circuit 15 and the inverter 16 in the IC. Can be

  In the above-described embodiment, an example has been described in which the CPU 20 receives the coincidence signal from the comparator 14 and obtains the approximate number of steps by the arithmetic processing performed by the CPU 20. However, the present invention is not limited to this example. Each time the CPU 20 receives a coincidence signal from 14, the CPU 20 may perform read access of the count value to the total number of steps read counter 13, thereby recognizing the approximate number of all the steps.

  In the above-described embodiment, the example in which the CPU 20 acquires (and recognizes and notifies) the count value of the total number of steps read counter 13 according to the operation of the user has been described. However, the present invention is not limited to this example. For example, the count value of the total step number reading counter 13 may be acquired (and recognized and notified) by the CPU 20 at every preset time interval.

  In the above embodiment, walking (the number of steps) is exemplified as the operation to be counted. However, the present invention is not limited to this example. For example, the operation number counting device counts the number of squats or other repetitive movements. Can be applied similarly. Furthermore, the present invention is not limited to the number of human movements (number of steps or squats), for example, a device that counts the number of movements of animals other than humans, or a device that counts the number of movements of articles and devices. The same applies to the above.
