Description

  The present invention relates to a heartbeat measuring device, a heartbeat measuring method, and a heartbeat measuring program which are worn on the body at exercise and measure the heart rate.

  In recent years, with the rise in health awareness, people who maintain and improve their health status by performing daily activities such as running, walking, and cycling, and those who aim to participate in competitions (races) such as marathon races are increasing. There is. Such people are very conscious and interested in measuring and recording their own health and exercise status numerically and data. At present, various measuring devices corresponding to such a request are marketed, and their health and exercise status are grasped by measuring and recording the number of steps, movement distance, heart rate, calorie consumption etc. be able to.

  As an example of such a measuring device, for example, Patent Document 1 discloses a measuring device for a heart rate in which a heart rate (signal) is not detected in a heart rate measuring device provided with a wearing detection unit such as a heart rate sensor attached to the body. There is disclosed a technology for saving power by cutting off the supply of power to a communication unit for transmitting and receiving data such as heart rate to an external device, judging that it is not worn on the body.

JP, 2009-240730, A

  In the heartbeat measuring device described in Patent Document 1 described above, in addition to the case where the heartbeat measuring device is removed from the wearing state (non-wearing state), the electrode surface of the heartbeat sensor in direct contact with the body is dry or Even when the position of the heartbeat sensor deviates during wearing, a state in which a heartbeat signal is not detected occurs, so it may be determined that the heartbeat measuring device is not worn. Here, once it is determined that the heartbeat measuring device is not worn and the power supply to the communication unit is cut off, the user takes appropriate measures (that is, wetting the electrodes or correcting the position of the heartbeat sensor) After that, unless the power supply to the communication unit is resumed, normal heartbeat measurement operation does not occur again. Therefore, when a state in which a heartbeat signal is not detected occurs, not only the measurement of the heart rate becomes impossible, but also there is a problem that the countermeasure for causing the normal operation to occur again becomes complicated.

  Further, in Patent Document 1 described above, since power supply to the communication unit is cut off at least when a heartbeat signal is not detected, constant power saving can be achieved, but the heartbeat measurement operation itself in the heartbeat sensor The problem is that power saving can not be achieved in the heart rate sensor and its peripheral circuits because it is always executed regardless of the wearing state of the heart rate measurement device. Here, the measurement method of continuously executing the heartbeat measurement operation is not limited to the heartbeat measurement device described in Patent Document 1 described above, and is a method adopted in the case of a heartbeat sensor that is generally commercially available. Therefore, this problem is also a problem that occurs in commercially available heart rate sensors.

  Therefore, in view of the above-described problems, the present invention automatically returns to the normal heartbeat measurement operation at an appropriate timing even when a condition where a heartbeat signal is not detected in the heartbeat sensor occurs, and is thus favorable. It is an object of the present invention to provide a heartbeat measuring device, a heartbeat measuring method, and a heartbeat measuring program capable of measuring a heart rate and reducing power consumption.

Note) 100). For example, as shown in FIG. 1 (b), the chest device 100 is roughly divided into a device main body having a function of detecting various information including the heart rate while the user US is exercising (for example, walking or traveling). 101, a belt portion 102 for mounting the device main body 101 on the chest by winding it around the chest of the user US, and a pair of detection electrodes 103a and 103b provided on the inner surface side of the belt portion 102 (side in contact with human body) And have.

  As shown in FIG. 1B, the heart rate sensor 110 is exposed on the inner surface side of the belt portion 102 for attaching the chest device 100 to the chest of the user US, and is disposed in direct contact with the chest of the user US. It has a pair of detection electrodes 103a and 103b. The heartbeat sensor 110 detects a change in the cardiac potential signal output from the detection electrodes 103a and 103b, and outputs it as heartbeat data. The heartbeat data is stored in a predetermined storage area of the sensor data memory 140.

  The acceleration sensor 120 detects at least a vibration applied to the device body 101 from the outside, and outputs it as vibration data. In addition, the acceleration sensor 120 detects the rate of change (acceleration) of the operating speed during movement of the user US, and outputs it as acceleration data. The acceleration data is stored in a predetermined storage area of the sensor data memory 140 in association with the heartbeat data.

  The sensor data memory 140 has a non-volatile memory, and correlates the heart rate data output from the heart rate sensor 110 described above and the acceleration data output from the acceleration sensor 120 with each other at each detection time, and stores the predetermined storage area. Save to Further, the sensor data memory 140 stores information such as the number of steps and the amount of activity calculated based on the heart rate calculated based on the heart rate data and the acceleration data in a predetermined storage area. The program memory 150 has a ROM (read only memory), and is configured to perform sensing operations in the heart rate sensor 110 and the acceleration sensor 120, data transfer operations in the communication module 170 described later, and notification operations in the notification unit 180 described later. Save a control program for realizing a predetermined function in The program memory 150 also stores an algorithm program for executing a series of heartbeat measurement processes described later, based on the heartbeat data from the heartbeat sensor 110 and the vibration data from the acceleration sensor 120. Also, the program memory 150 stores an algorithm program that executes processing for measuring, for example, the number of steps during movement and the amount of activity based on acceleration data from the acceleration sensor 120. The working memory 160 has a RAM (random access memory), and temporarily stores various data used or generated when the control program and the algorithm program are executed. A part or all of the sensor data memory 140 may have a form as a removable storage medium such as a memory card, for example, and may be configured to be removable from the chest device 100.

  The control unit 130 is an arithmetic processing unit such as a CPU (central processing unit) or an MPU (microprocessor) having a clocking function. The control unit 130 performs processing in accordance with the control program stored in the program memory 150 to perform sensing operation in the heartbeat sensor 110 or the acceleration sensor 120, data transfer operation in the communication module 170, notification operation in the notification unit 180, etc. The operation in each configuration is controlled to realize a predetermined function. Further, the control unit 130 performs processing according to the above-described algorithm program to activate the heartbeat sensor 110 based on the vibration data from the acceleration sensor 120, and executes a series of heartbeat measurement processing described later. Perform an action to measure your heart rate. Further, the control unit 130 performs an operation according to the above-described algorithm program to execute an operation of measuring and collecting, for example, the number of steps during movement and the amount of activity based on the acceleration data from the acceleration sensor 120. The control program or algorithm program executed by the control unit 130 may be incorporated in advance in the control unit 130.

  As illustrated in FIG. 3, the communication module 170 transmits at least information including the heart rate calculated based on the heart rate data acquired by the heart rate sensor 110 to the information processing device 300 provided outside the chest device 100. It functions as an output interface when transferring. Here, as a method of transferring information including heart rate to the information processing apparatus 300 via the communication module 170, various wireless communication methods, wired communication methods via communication cables, removable storage such as a memory card, etc. A scheme via a medium can be applied.

  When the above information is transferred by a wireless communication method, for example, it is formulated as a low power consumption communication standard in Bluetooth (registered trademark) communication which is a short distance wireless communication standard for digital devices, or in this communication standard. Bluetooth Low Energy (LE) communication, or WiFi (wireless fidelity (R)) communication that enables wireless communication over a relatively long distance or equivalent communication The scheme can be applied well. When the above information is transferred by a wired communication method, for example, a USB (Universal Serial Bus) communication cable used for connection between a personal computer and a peripheral device, or a communication cable of an equivalent communication method is preferable. It can be applied to

  For example, as shown in FIG. 3, as the information processing apparatus 300 to which information including heart rate is transferred through the communication module 170, electronic devices such as the personal computer 301, the smartphone 302, and the tablet terminal 303 are applied. can do. The information processing apparatus 300 displays the information included in the information processing apparatus 300 by performing the analysis including the transferred heart rate as it is or after the completion of the heart rate measurement process or after the exercise of the user US. It is displayed on the part in a predetermined display form such as numerical values and graphs. By viewing the display of the information processing apparatus 300, the user US can accurately grasp various information including his / her heart rate.

  The notification unit 180 has, for example, a vibration unit and an acoustic unit, and in a series of heartbeat measurement processes in the control unit 130, predetermined vibration information is obtained when the measurement of the heart rate is not normally performed during the exercise of the user US. Sound information is generated to notify the user US of an abnormal state of the chest device 100. For example, the vibration unit has a vibration device (vibrator) such as a vibration motor or a vibrator, and generates vibration information such as a predetermined vibration pattern or its strength to notify the user US of an abnormal state through a tactile sense. The sound unit has sound devices such as a buzzer and a speaker, and generates sound information such as a predetermined tone color, a sound pattern, and a voice message to notify the user US of an abnormal state through hearing. Note that the notification unit 180 may include one or both of the vibration unit and the sound unit described above.

  The power supply unit 190 supplies driving power to each configuration inside the device body 101 of the chest device 100. The power supply unit 190 can apply, for example, a primary battery such as a commercially available coin battery or button battery, or a secondary battery such as a lithium ion battery or a nickel hydrogen battery. In addition to the primary battery and the secondary battery, the power supply unit 190 can also apply a power supply based on energy harvesting technology that generates electric energy using energy such as vibration, light, heat, and electromagnetic waves.

(Heart measurement method)
Next, a heartbeat measuring method in the above-described heartbeat measuring device will be described.
FIG. 4 is a flowchart showing a heartbeat measuring method executed by the heartbeat measuring apparatus according to the first embodiment. FIG. 5 is a repetitive (intermittent) operation setting process applied to the heartbeat measuring method according to the present embodiment Is a flowchart showing FIG. 6 is a waveform diagram for explaining a heartbeat waveform detection process applied to the heartbeat measurement method according to the present embodiment.

  In the heartbeat measuring method in the heartbeat measuring apparatus having the configuration as described above, for example, as shown in FIG. 4, first, as an initial state, the chest device 100 has the main power turned on, but only the acceleration sensor 120 is activated. In the sleep state (step S102). That is, in this initial state (sleep state), the heartbeat sensor 110, the communication module 170, the notification unit 180, etc. are not activated (that is, the function is stopped), and the power consumption is zero or very small. It is set to the state. On the other hand, the acceleration sensor 120 continues the sensing operation at a predetermined cycle (for example, a cycle longer than the normal sensing operation described later; lower sampling frequency), and the power consumption is set to be minimized. There is. Also, in the initial state (sleep state), the chest device 100 is not worn, for example, on the body of the user US, and is, for example, in a stationary state on a table or the like.

  Then, when the user US lifts the chest device 100 to put on the body and the like, and vibration is applied to the chest device 100, the acceleration sensor 120 detects the vibration (acceleration) and outputs it as vibration data ( Step S104). When acquiring the vibration data from the acceleration sensor 120, the control unit 130 activates the heartbeat sensor 110 in the initial state and stopping the sampling operation (step S106). That is, in response to an action for the user US to use the chest device 100, the heart rate measurement function of the chest device 100 can be automatically activated. Here, the sampling operation in the heartbeat sensor 110 is continuously performed at a sampling frequency of, for example, 200 Hz. Further, at this time, the control unit 130 sets the sampling operation of the acceleration sensor 120 to a normal cycle (for example, a high sampling frequency of 200 Hz that is the same as that of the heart rate sensor) and executes it.

  Next, the control unit 130 outputs an interrupt signal for ending the heart rate measurement process from another control process (main flow; not shown) executed in parallel with the heart rate measurement process according to the present embodiment. It is determined whether it is set (step S108). Then, when it is determined that there is an interrupt signal of the process end, the control unit 130 stops the functions of the heart rate sensor 110, the communication module 170, the notification unit 180, etc., and only the acceleration sensor 120 is activated. The chest device 100 is shifted to the sleep state (that is, the above-described initial state) (step S126), and the heartbeat measurement process is ended.

  On the other hand, when it is determined in step S108 that there is no interrupt signal for process end, the control unit 130 executes the sampling operation by the heart rate sensor 110 (step S110). Note that the sampling operation by the heartbeat sensor 110 executed here may be performed continuously or may be repeatedly repeatedly performed again after being stopped for a certain period of time. The term "intermittently repeated execution" means the following condition. That is, when the heartbeat waveform detected after measuring the heartbeat data is not measured, the operation is performed again after stopping for a predetermined time (interval time). The measurement-impossible state such as the wearing condition of the normal chest equipment 100 or the like is not always eliminated immediately, and when measurement is not possible even in the re-operation, after being stopped again for a predetermined time (interval time), It will be operated again. That is, when the heart rate sensor 110 is activated from the above-described initial state, or as described later, when the heart rate waveform is detected from the heart rate data and the heart rate is calculated, the sampling operation is continuously performed. (Continuous operation). On the other hand, as described later, when the heartbeat waveform is not continuously detected from the heartbeat data, the sampling operation is intermittently and repeatedly performed every set execution cycle, and so on (other than when the sampling operation is performed) The sampling operation is stopped at the time of (1) (intermittent repetition operation).

  Next, the control unit 130 executes a process of detecting a heartbeat waveform from the heartbeat data acquired from the heartbeat sensor 110 based on a waveform pattern, a signal level, and the like (step S112). Specifically, after the noise is removed or reduced by the filtering process on the signal waveform of the heartbeat data acquired from the heartbeat sensor 110 in step S110, the process of determining the waveform pattern is performed and the process of extracting the heartbeat waveform is executed. Do. FIG. 6A is a diagram showing an example of a signal waveform (output waveform) of heartbeat data. Here, a state where noise is always mixed and the shape of the heartbeat waveform can not be determined. As shown in FIG. 6B, when a heartbeat waveform is included by executing predetermined filter processing or waveform pattern determination processing on such an output waveform, as shown in FIG. Only characteristic waveform components indicating a heartbeat waveform are extracted. On the other hand, when the heartbeat waveform is not included, a waveform component indicating the heartbeat waveform is not extracted as a detection waveform.

  Next, the control unit 130 determines whether or not a heartbeat waveform is detected by the series of heartbeat waveform detection processing in step S112 (step S114). Then, when it is determined that the heartbeat waveform is detected, the control unit 130 determines whether the current sampling operation in the heartbeat sensor 110 is continuously performed (continuous operation) (step S116). When it is determined that the current sampling operation is not the continuous operation, the control unit 130 shifts the sampling operation of the heart rate sensor 110 to the continuous operation (step S118), and executes the next step S120. On the other hand, when it is determined in step S116 that the current sampling operation is the continuous operation, an interval value is calculated based on the heartbeat waveform detected in step S112 (step S120). Specifically, the control unit 130 measures the interval value 1 by measuring the time between peak values of the signal level in each heartbeat waveform in the output waveform (FIG. 6B) when the heartbeat waveform is detected. Calculate interval value 2.

Next, the control unit 130 calculates a heart rate based on the calculated interval value (step S122). Specifically, the control unit 130 stores, for example, the past 10 interval values, and uses the average value to calculate the heart rate (the number of measurements per minute based on the following equation (11); Calculate the unit BPM). Here, a calculation formula in the case where the sampling operation is performed at a sampling frequency of 200 Hz is shown.
Heart rate = 60 / (average interval value for the past 10 times × 0.005) (11)

  Next, the control unit 130 stores the heart rate calculated based on the equation (11) in a predetermined storage area of the sensor data memory 140 (step S124), and returns to step S108 to repeat the above series of processes. Run. Therefore, after step S124, when the processes after step S108 are repeatedly executed, the sampling operation by the heart rate sensor 110 in step S110 is continuously performed.

  If it is determined in step S114 that the heartbeat waveform is not detected in the series of heartbeat waveform detection processing in step S112, the control unit 130 continues the heartbeat waveform in the heartbeat waveform detection processing in steps S112 and S114. It is determined whether or not it has been detected (step S132). Specifically, the control unit 130 stores the detection result in the heartbeat waveform detection process in steps S112 and S114, and only when the state in which the heartbeat waveform is not detected continues for a predetermined time (for example, 3 minutes) or more. It is determined that the heartbeat waveform is not continuously detected. Thereby, for example, it is possible to exclude the state that the heartbeat waveform is not detected accidentally only this time. Then, if it is determined that the state in which the heartbeat waveform is not detected is not continuing, that is, if the heartbeat waveform is continuously detected and is not detected only this time, the process returns to step S108 and the above-described series Repeat the process of. Therefore, after step S132, when the processes after step S108 are repeatedly executed, the sampling operation by the heart rate sensor 110 in step S110 is performed in the currently set operation state (continuous operation or intermittent repetition operation). Be done.

  On the other hand, when it is determined in step S132 that the heartbeat waveform is not continuously detected, the control unit 130 intermittently and repeatedly executes the current sampling operation in the heartbeat sensor 110 (intermittent repetition It is determined whether it is an operation | movement) (step S134). Then, when it is determined that the current sampling operation is not the intermittent repetition operation, the control unit 130 shifts the sampling operation in the heartbeat sensor 110 to the intermittent repetition operation (step S136), and proceeds to step S108. Back, the above-described series of processes are repeatedly executed. Here, the execution cycle (interval) Tint of the sampling operation that defines the intermittent repetition operation is, for example, the time T1 (for example, 10 seconds) which becomes the minimum value (shortest) in the intermittent repetition operation setting process shown in step S142 and subsequent steps. Set to Therefore, after step S136, when the processes after step S108 are repeatedly performed, the sampling operation by the heart rate sensor 110 in step S110 is intermittently and repeatedly performed in an execution cycle Tint = T1.

  On the other hand, when it is determined in step S134 that the current sampling operation is the intermittent repetition operation, for example, as shown in FIG. 5, the control unit 130 defines an execution cycle that defines the current intermittent repetition operation. (Interval) It is determined whether it is time T1 (for example, 10 seconds) at which Tint becomes the minimum value (shortest) (step S142). Then, when the execution cycle Tint of the sampling operation is the time T1, the control unit 130 changes the execution cycle Tint of the sampling operation to a time T2 (for example, 30 seconds) next smaller (shorter) next to the time T1. After step S144), the process returns to step S108 to repeatedly execute the series of processes described above.

  On the other hand, when the execution cycle Tint of the sampling operation is not the time T1 in step S142, the control unit 130 determines that the current execution cycle Tint of the sampling operation is smaller (shorter) T2 (for example, 30 seconds) next to the time T1. It is determined whether or not (step S146). Then, when the execution cycle Tint of the sampling operation is the time T2, the control unit 130 changes the execution cycle Tint of the sampling operation to a time T3 (for example, 1 minute) next smaller (shorter) as the time T2. After step S148), the process returns to step S108 to repeatedly execute the above-described series of processes.

  On the other hand, when the execution cycle Tint of the sampling operation is not the time T2 in step S146, the control unit 130 determines that the current execution cycle Tint of the sampling operation is the second (short) time T3 (for example, 1 minute) next to the time T2. It is determined whether or not (step S150). When the execution cycle Tint of the sampling operation is the time T3, the control unit 130 changes the execution cycle Tint of the sampling operation to a time T4 (for example, 3 minutes) next smaller (shorter) than the time T3 (for example, 3 minutes). After step S152), the process returns to step S108 to repeatedly execute the series of processes described above. Therefore, after steps S144, S148, and S152, when the processing after step S108 is repeatedly executed, the sampling operation by the heart rate sensor 110 in step S110 is performed at the execution cycle Tint set in each of steps S144, S148, and S152. It is repeatedly executed intermittently.

  On the other hand, when the execution cycle Tint of the sampling operation is not time T3 in step S150, control unit 130 determines whether or not the acceleration sensor 120 detects the acceleration associated with the motion of user US (step S154). . Then, when it is determined that the acceleration is detected by the acceleration sensor 120, the control unit 130 is in a state where the user US continues exercise but the heart rate measurement can not be normally performed (the measurement impossible state). In the notification unit 180, an abnormal state is notified on the basis of vibration information and sound information (step S156). That is, when the control unit 130 can not continuously detect the heartbeat waveform, it shifts the sampling operation of the heartbeat sensor 110 from the continuous operation to the intermittent repetition operation, and can not continuously detect the heartbeat waveform. Is set to gradually increase the execution cycle of the sampling operation that defines the intermittent repetition operation. Then, if it becomes possible to continuously detect the heartbeat waveform during the intermittent repetitive operation, the sampling operation is shifted to the continuous operation to measure the heart rate. On the other hand, even though the sampling operation in the heart rate sensor 110 is intermittently repeated and performed for a long time, it is a case where the heart rate waveform can not be detected continuously and the user US performs exercise by the acceleration data from the acceleration sensor 120. If it is determined that (for example, the number of steps is normally measured), it is determined that the heart rate measurement process in the heart rate measurement process can not be normally performed. In this abnormal state, specifically, the user US wears the heartbeat sensor 110 on the chest, but, for example, the electrode surface of the heartbeat sensor 110 is dry, or the electrode position is shifted during the wearing. (Ie, mounting failure). In such a case, the control unit 130 improves the abnormal state to the user US (that is, wets the electrodes of the heartbeat sensor 110 by notifying the user US of the abnormal state through the sense of touch and the sense of hearing by the notification unit 180). And to take action to correct the position). As a result, it is possible to prevent in advance the measurement defect that the user US notices after exercise that the heart rate during exercise can not be measured due to the poor attachment of the chest device 100, and the measurement of a good heart rate Can be realized.

  After step S156, the control unit 130 stops the functions of the heartbeat sensor 110, the communication module 170, the notification unit 180, and the like, and puts the chest in the sleep state (that is, the initial state described above) in which only the acceleration sensor 120 is activated. The device 100 is shifted (step S158), and the heartbeat measurement process is ended.

  On the other hand, when it is determined in step S154 that acceleration due to exercise is not detected, the control unit 130 executes step S158 to shift the chest device 100 to the sleep state, and perform a heartbeat measurement process. finish. That is, although the control unit 130 intermittently and repeatedly performs the sampling operation in the heart rate sensor 110 for a long time, it is a case where the heart rate waveform can not be continuously detected, and the acceleration data from the acceleration sensor 120 When it is determined that the user US is not exercising according to, for example, it is determined that the chest device 100 is removed from the body and is in a state of being placed stationary on a table or the like. In such a case, the control unit 130 quickly shifts the chest device 100 to the sleep state. As a result, it is possible to suppress the power consumption in the case where the chest device 100 is removed or the like.

  Then, after the series of heartbeat measurement processes described above are completed, as shown in FIG. 3, the various information such as the heart rate during exercise, the number of steps, and the amount of activity collected by the chest device 100 is the communication module 170. Is transferred to the external information processing apparatus 300 using a predetermined wireless communication method, a wired communication method, a communication method via a storage medium, or the like. As a result, the information processing apparatus 300 displays the information including the transferred heart rate as it is or by performing a more detailed analysis and displaying the information in a predetermined display form such as a numerical value or a graph on the display unit. By viewing the display of the information processing apparatus 300, the user US can accurately grasp various information including his / her heart rate.

  As described above, in the present embodiment, when the chest device 100 is not worn on the body, or a mounting failure such as drying of the electrode surface or a shift in the mounting position occurs and the heartbeat waveform is not detected. The power consumption can be reduced by shifting the sampling operation of the heartbeat sensor 110 to the intermittent repetition operation. Also, when the chest device 100 is properly worn and a heartbeat waveform is detected, the sampling operation is shifted to continuous operation at an appropriate timing (that is, the normal heartbeat measurement operation is automatically resumed). ) Various information including heart rate during exercise can be measured well.

  In the heartbeat measurement method described in the present embodiment, the case where the sampling operation of the heartbeat sensor 110 is continuously performed in the state immediately after the heartbeat sensor 110 is activated from the initial state (sleep state) has been described. The present invention is not limited to this. Immediately after the heartbeat sensor 110 is activated from the initial state (sleep state), the sampling operation may be set to be repeatedly and intermittently performed, for example, at one minute intervals. According to this, in step S104 shown in the flow chart of FIG. 4, the heart rate sensor 110 is sampled until the chest device 100 is put on and the heart beat can be actually measured by lifting the chest device 100. Since the operation can be executed intermittently and repeatedly, the power consumption during that time can be minimized.

  Further, in the heartbeat measuring method described in the present embodiment, when the execution cycle Tint defining the intermittent repetitive operation of the sampling operation is set to be gradually longer (for example, 10 seconds, 30 seconds, 1 minute, Although 3 minutes) was demonstrated, this invention is not limited to this. For example, the execution cycle of the sampling operation may be set to a specific fixed time. Also in this case, when the improper mounting of the chest device 100 is improved during the intermittent repetitive operation and the heartbeat waveform is detected from the heartbeat data, the sampling operation is performed based on the heartbeat measurement process described above. Shifts to continuous operation.

  In particular, when the execution cycle that defines the intermittent repetition operation of the sampling operation is set to a specific fixed time, if the heartbeat waveform is not continuously detected, the sleep state is reached in a relatively short time. The processing load on the control unit 130 can be reduced, and the power consumption can be reduced. Note that, as described above, when the execution cycle that defines the intermittent repeat operation of the sampling operation is set to be gradually longer, the intermittent repeat will be continued for a relatively long time. If a heartbeat waveform is detected during the return operation, the sampling operation can be shifted to continuous operation at an appropriate timing, and the heart rate can be measured well.

(Modification 1)
FIG. 7 is a flowchart showing a first modification of the intermittent repetition operation setting process applied to the heartbeat measuring method according to the present invention. Here, the same processing as that of the first embodiment described above is denoted by the same reference numeral to simplify the description.

  In the first embodiment described above, the sampling operation of the heart rate sensor 110 can be shifted to the intermittent repetition operation to reduce the power consumption when the chest device 100 is not attached or when the attachment is defective. In addition, in the case where the chest device 100 is worn properly, the operation and effect that various information including the heart rate during exercise can be measured favorably are described. Then, after shifting the sampling operation of the heartbeat sensor 110 to the intermittent repetition operation as shown in the flowchart of FIG. 5 as an example of the heartbeat measurement method (intermittent repetition operation setting processing) for obtaining this action and effect, In the case where the heartbeat waveform is not detected for a predetermined time or more, the chest device 100 is put into the sleep state to show a method of further reducing the power consumption.

  The present invention is not limited to this, and has a modified example in which the sampling operation in the heart rate sensor 110 is continued with the intermittent repetition operation so that the notification operation of the abnormal state and the transition to the sleep state are not performed. It may be one. That is, in the first modification of the present invention, as shown in the flowchart of FIG. 7 instead of the flowchart of FIG. 5, in the process of determining the execution period of the sampling operation in step S150, when the execution cycle Tint is not time T3. The control unit 130 returns to step S108 shown in the flowchart of FIG. 4 as it is, and repeatedly executes the series of heartbeat measurement processes described above. By applying such a processing procedure, it is possible to obtain the following effects in addition to the effects shown in the first embodiment described above.

  That is, in the first embodiment described above, the heartbeat measurement method has been mainly described, but in the present invention, exercise is performed based on the acceleration data acquired from the acceleration sensor 120 in parallel and independently of the heartbeat measurement processing described above. The number of steps inside and the amount of activity are measured. Here, based on the above-described heartbeat measurement process, the number of steps and activities can be taken even during a period in which the sampling operation of the heartbeat sensor 110 is intermittently and repeatedly executed or in a period in which the heartbeat sensor 110 is set to sleep. Amount etc. are measured. Therefore, as in the first modification, a state in which the chest device 100 described in the first embodiment described above is removed from the chest by applying the method of continuing the sampling operation in the heart rate sensor 110 with intermittent repetition operation. Then, by carrying the user US in a pocket, a bag or the like, exercise information such as the number of steps and the amount of activity excluding the heart rate can be favorably measured while suppressing the power consumption as much as possible. Therefore, in the first modification, various exercise information can be measured with a single device (chest device 100) not only during a specific exercise such as running but also during daily operation. The scope of utilization of the heart rate measuring device can be expanded.

(Modification 2)
FIG. 8 is a flowchart showing a second modification of the intermittent repetition operation setting process applied to the heartbeat measuring method according to the present invention. Here, the same processing as that of the first embodiment described above is denoted by the same reference numeral to simplify the description.

  In the first embodiment described above, when the heartbeat waveform is not continuously detected from the heartbeat data acquired by the heartbeat sensor 110, the sampling operation of the heartbeat sensor 110 is shifted to the intermittent repetition operation, and the heartbeat is The heartbeat measurement process has been described, which shifts the sampling operation to continuous operation and measures the heart rate when the waveform is continuously detected.

  The present invention is not limited to this, and when the motion pattern of the user US changes during the intermittent repeating operation of the sampling operation, the sampling operation is shifted to the continuous operation to measure the heart rate. It may have a modified example. That is, in the second modification of the present invention, as shown in the flowchart of FIG. 8 instead of the flowchart of FIG. 5, in the process of determining the execution period of the sampling operation in step S150, if the execution cycle Tint is not time T3. The control unit 130 determines whether an irregular acceleration not related to the motion (for example, walking etc.) of the user US is detected (vibration is detected) by the acceleration sensor 120 (step S162). Then, when an irregular acceleration is detected by the acceleration sensor 120, the control unit 130 shifts the sampling operation of the heart rate sensor 110 to the continuous operation (step S164), and then the steps shown in the flowchart of FIG. Returning to S108, the series of heartbeat measurement processes described above are repeatedly executed. That is, when the irregular movement different from the motion of the user US is applied in a state where the sampling operation of the heartbeat sensor 110 continues the intermittent repetition operation due to the poor attachment of the chest device 100 to the body (ie, When the movement pattern of the user US changes), the control unit 130 wets the electrodes of the chest device 100 or corrects (remembers) the mounting position, for example, in a state where the user US stops or sits down. It judges that it is what, sampling operation is immediately transferred to continuous operation, and heart rate measurement operation is executed.

  On the other hand, when the irregular acceleration is not detected in step S162, the process returns to step S108 shown in the flowchart of FIG. 4 as it is and repeatedly executes the series of heartbeat measurement processes described above. In the second modification, by applying such a processing procedure, in addition to the effects shown in the first embodiment described above, heart rate measurement can be rapidly performed based on a change in the motion pattern of the user US. Since the operation can be started, the heart rate can be measured well at an appropriate timing.

Here, the acceleration sensor 220, the sensor data memory 240, the program memory 250, the work memory 260, and the power supply unit 290 have substantially the same functions as those of the first embodiment described above.

  Here, the input operation unit 210 of the wrist device 200 is used to set various items to be displayed on the display unit 280 described later, input operations of various setting values related to other operations of the wrist device 200, and the like. The input operation unit 210 may be a button switch provided on the device main body 201 as shown in FIG. 9C, or a touch panel provided on the front surface (view side) of the display unit 280 described later.

(Heart measurement method)
Next, a heartbeat measuring method in the above-described heartbeat measuring device will be described.
FIG. 12 is a flowchart showing a heartbeat measuring method executed by the heartbeat measuring device according to the second embodiment. Here, processing equivalent to that of the first embodiment described above is denoted by the same reference numeral to simplify the description.

  In the heartbeat measuring method in the heartbeat measuring apparatus according to the second embodiment, for example, as shown in FIG. 12, first, as an initial state, the chest power of the chest device 100 is turned on, but the heartbeat sensor 110 is activated. It is not in the sleep state (that is, the function is stopped) (step S202). In this state, the chest device 100 is set to a state in which the amount of power consumption is very small. Further, the wrist device 200 is in a standby state in which the main power supply is turned on and at least the acceleration sensor 220 is activated. Here, the acceleration sensor 220 continues the sensing operation at a predetermined cycle (for example, a cycle longer than the normal sensing operation; a sampling frequency lower than that of the normal sensing operation), and the power consumption thereof is set to be minimized. . Further, in the standby state, the wrist device 200 is not mounted on, for example, the body of the user US, and is in a stationary state, for example, on a table or the like.

  Then, when the user US acts to lift the chest device 100 and the wrist device 200 to the body and the vibration is applied to the wrist device 200, the acceleration sensor 220 detects the vibration (acceleration) and the vibration data Output (step S204). When the control unit 230 acquires vibration data from the acceleration sensor 220, the control unit 230 generates an activation signal for activating each component including the heart rate sensor 110 of the chest device 100. Further, the control unit 230 performs control for establishing communication connection by Bluetooth (registered trademark) communication or the like between the chest device 100 and the wrist device 200 via the communication module 270 (step S205). ). Then, when the communication connection with the chest device 100 is established, the control unit 230 transmits a start signal to the chest device 100. When the chest device 100 receives the activation signal from the wrist device 200, the chest device 100 activates the heartbeat sensor 110 in the initial state and stopping the sampling operation (step S206). Hereinafter, in the same manner as the flowchart (see FIG. 4 and FIG. 5) shown in the first embodiment described above, a series of heartbeat measurement processes after step S208 are executed. Here, each process of steps S208 to S236 shown in FIG. 12 corresponds to each process of steps S108 to S136 shown in FIG.

  If it is determined in step S208 that an interrupt signal for ending the heartbeat measurement process is output, the control unit 230 stops the functions of the heartbeat sensor 110, the notification unit 180, and the like in step S226. The chest device 100 is moved to the sleep state (that is, the above-described initial state), and the communication module 170 is controlled to cut off the communication connection with the wrist device 200, and the heartbeat measurement process is ended.

  Further, in step S222, the calculated heart rate is stored in a predetermined storage area of the sensor data memory 140 in step S224, and also transferred to the wrist device 200 as needed through the communication module 170. As a result, the wrist device 200 can set various information such as the heart rate transferred from the chest device 100, the number of steps acquired and calculated in the wrist device 200, and the amount of activity, etc. Display in real time in display form.

  Then, after the series of heartbeat measurement processes described above are completed, the heart rate during exercise collected by the chest device 100 and the number of steps acquired by the wrist device 200 as in the first embodiment (see FIG. 3) And various amounts of information such as the amount of activity are transferred to the external information processing apparatus 300 through the communication modules 170 and 270 using a predetermined wireless communication method, a wired communication method, a communication method via a storage medium, etc. Ru. Thereby, the information processing apparatus 300 displays the information including the transferred heart rate on the display unit in a predetermined display form such as a numerical value or a graph.

  Therefore, in the present embodiment, as in the first embodiment described above, when the heartbeat waveform is not detected during the heartbeat measurement process in the chest device 100, the sampling operation of the heartbeat sensor 110 is intermittently repeated. Because it is migrated, power consumption can be reduced. Further, in the present embodiment, the function (sampling operation) of the heart rate sensor 110 in the initial state (or sleep state), such as when the chest device 100 is not equipped with an acceleration sensor and the chest device 100 is not attached. Can be significantly suppressed, and the configuration of the chest device 100 can be simplified. Also, if the heartbeat waveform is detected while the sampling operation of the heartbeat sensor 110 is intermittently repeated, the sampling operation is shifted to the continuous operation at an appropriate timing (that is, it is automatically switched to the normal heartbeat measurement operation) Heart rate during exercise can be measured well.

  Further, in the present embodiment, various information such as the heart rate acquired by the chest device 100 and the number of steps and the amount of activity acquired by the wrist device 200 are provided to the user US in real time through vision in the wrist device 200. Therefore, the user US can accurately grasp the biological information and exercise information of oneself during exercise and the operating state of the chest device 100. In addition, by viewing the display of the information processing apparatus 300 after the end of exercise, the user US can accurately grasp various information including his / her heart rate.

On the other hand, the wrist device 200 has a function of displaying various information including the heart rate transferred from the chest device 100 on the display unit 280 in a predetermined display form. As described above, the chest device 100 and the wrist device 200 have a cooperative relationship in which various types of information acquired by the chest device 100 are transferred to the wrist device 200 and displayed.

  Then, in the chest device 100 having such a cooperative relationship, the acceleration sensor 120 detects a vibration due to an operation such as the user US lifting the chest device 100, and the communication module 170 with the wrist device 200. When the communication connection is established (corresponding to steps S204 and S205 in the flowchart shown in FIG. 12), the heart rate sensor 110 is activated from the initial state (sleep state), and the series of heart beats shown in the above embodiments Execute measurement processing. Various types of information including the heart rate acquired in the chest device 100 are transferred to the wrist device 200 at any time via the communication module 170 and displayed on the display unit 280 of the wrist device 200 in real time in a predetermined display form.

  Therefore, in the third modification, since various types of information including the heart rate acquired in chest device 100 are provided to user US in real time through sight in list device 200, user US is his / her living body while exercising. Information, exercise information, and the operating state of the chest device 100 can be accurately grasped.

  In each of the above-described embodiments and modifications, the chest device 100 attached to the chest of the user US and the wrist device 200 attached to the wrist are shown as the heartbeat measuring device, but the present invention is limited thereto It is not a thing. That is, the heartbeat measuring device according to the present invention may be a single or separate device provided with at least a heartbeat sensor and an acceleration sensor (or a vibration sensor), for example, an existing mobile phone, a smartphone, an eyeglass type A terminal etc. can also be applied.
