  As shown in FIG. 3, the measurement mode is set to any one of the walking measurement mode, the non-walking measurement mode, the first sleep measurement mode, and the second sleep measurement mode based on the activity state of the user. The measurement of the activity state is preferably performed in a shorter cycle as the measurement mode corresponds to the state where the activity amount per unit time of the user is higher.

  The walking measurement mode is a mode in which the user is set in a state of exercising such as walking, and measures the number of walks, calories consumed by the exercise, and the like. The non-walking measurement mode is a mode in which the user is set in a state of performing daily life activities such as housework and desk work other than exercise, and is a mode for measuring the amount of movement associated with daily activities and calorie consumption due to daily activities. .

  The first sleep measurement mode is set in a state in which the user is in shallow sleep (for example, non-REM sleep), and the second sleep measurement mode is set in a state in which the user is in deep sleep (for example, REM sleep). The first and second sleep measurement modes are modes for measuring the amount of body movement during sleep, calorie consumption due to body movement, and the like. For example, shallow sleep and deep sleep are classified based on the amount of body movement during sleep.

  As shown in FIG. 3, the communication mode is set to one of the normal communication mode, the non-communication mode, the first power saving mode, and the second power saving mode corresponding to the surrounding environment or the measurement mode described above. .

  The non-communication mode is a mode that is set in an environment where the use of radio waves is restricted, for example, in an aircraft in a take-off and landing state, and the communication frequency is set to 0 and communication is stopped. In the non-communication mode, the measurement mode is set to one of the walking measurement mode, the non-walking measurement mode, the first sleep measurement mode, and the second sleep measurement mode. The normal communication mode is a mode that is set in correspondence with the state in which the user is exercising, that is, the walking measurement mode, and communicates at the first communication frequency (approximately several tens of milliseconds).

  The first power saving mode is set corresponding to a state in which the user is performing a living activity, that is, the non-walking measurement mode, or is set corresponding to a state in which the user is in a shallow sleep, that is, the first sleep measurement mode. In this mode, communication is performed at a second communication frequency (a cycle of about 1 minute to several minutes) lower than the first communication frequency. The second power saving mode is set corresponding to a state in which the user is in deep sleep, that is, the second sleep measurement mode, and communicates at a third communication frequency (about 1 hour to several hours) lower than the second communication frequency. Mode.

  As shown in FIG. 4, the communication mode transits from the normal communication mode or the first power saving mode to the non-communication mode, or transits from the non-communication mode to the normal communication mode. The communication mode also changes between the normal communication mode and the first power saving mode and between the first power saving mode and the second power saving mode.

  The transition from the normal communication mode or the first power saving mode to the non-communication mode is performed using a predetermined operation performed on the information terminal 20 as a trigger in an environment where use of radio waves is restricted. The transition from the non-communication mode to the normal communication mode means that after the non-communication mode is set, the user's activity state changes from a state in which the activity associated with the daily activity is performed to a state in which the operation associated with the daily activity is performed. Occurs when changed. The operation exceeding the operation associated with the daily activity is, for example, an operation such as walking a predetermined amount or shaking the activity meter 10 violently from side to side.

  Transition between the normal communication mode and the first power saving mode is performed in response to switching between the walking measurement mode and the non-walking measurement mode. Such switching of the measurement mode occurs when the activity state of the user changes between the state of exercising and the state of performing daily activities. Such a change in the activity state is triggered by, for example, a change in the presence / absence of an action associated with walking, or a change in posture such as standing or sitting.

  The transition between the first power saving mode and the second power saving mode is performed in response to switching between the first sleep measurement mode and the second sleep measurement mode. Such switching of the measurement mode occurs when the activity state of the user changes between a light sleep state and a deep sleep state. Such a change in state is triggered by, for example, a change in posture such as a sitting state or a sleeping state, or a change in the amount of body movement accompanying sleep.

  Next, an activity amount measuring method according to an embodiment of the present invention will be described with reference to FIGS. 5 and 6 are sequence diagrams showing the activity amount measuring method according to the embodiment of the present invention. Although not shown in FIGS. 5 and 6, the activity meter 10 measures the activity state in the set measurement mode and continuously generates and stores activity data.

  The information terminal 20 determines whether or not the activity amount measurement application is activated (S11). When the information terminal 20 is located in the communication area of the activity meter 10 in a state where the activity amount measurement application is activated, the information terminal 20 establishes communication with the activity meter 10 (S12).

  When the information terminal 20 establishes communication, it notifies the activity meter 10 of a measurement mode request (S13), and the activity meter 10 notifies the information terminal 20 of the current measurement mode (S14). In response to the notification of the measurement mode, the information terminal 20 sets a communication mode corresponding to the measurement mode (S15), and notifies the activity meter 10 of the set communication mode (S16).

  In parallel with the measurement of the activity state, the activity meter 10 transmits the activity data to the information terminal 20 at a communication frequency determined for each communication mode (S17). The activity meter 10 transmits the activity data generated between the previous transmission timing and the current transmission timing. When receiving the activity data, the transmission information terminal 20 processes the activity data (S18). The information terminal 20 records and displays activity amount data, or transmits it to a server device via a network.

  FIG. 7 is a diagram illustrating a display example of activity amount data. FIG. 7 shows an information terminal 20 in which a display area A1 of the calorie consumption graph and a display area A2 of the calorie consumption of the day are provided on the screen D. On the screen D of the information terminal 20, by touching the icon I, the display of the graph in the display area A1 is switched on a daily basis, a week basis, or a monthly basis. In addition, the data displayed in the display area A1 can be switched by swiping the display area A1 left and right.

  Returning to the description of FIG. 5, the activity meter 10 determines whether or not switching of the measurement mode is necessary in parallel with the transmission of the activity data (S17) (S19). As described with reference to FIG. 4, the measurement mode is switched between the walking measurement mode, the non-walking measurement mode, the first sleep measurement mode, and the second sleep measurement mode. The determination is made based on a change in the activity state of the user.

  If it is determined in S19 that the measurement mode needs to be switched, the activity meter 10 switches the measurement mode (S20), and transmits the switched measurement mode to the information terminal 20 (S14). Then, the information terminal 20 sets a communication mode corresponding to the measurement mode (S15), and notifies the activity meter 10 of the set communication mode (S16). As a result, the lower the activity amount of the user, the lower the communication frequency is set and the activity meter 10 is notified. Therefore, the communication frequency can be set according to the activity state of the user without providing the activity meter 10 with a manual switch. Can be suppressed.

  On the other hand, as shown in FIG. 6, the information terminal 20 determines whether or not switching to the non-communication mode is necessary in parallel with the activity amount data processing (S18) (S21). As described with reference to FIG. 4, the switching to the non-communication mode is performed from the normal communication mode or the first power saving mode, and the necessity for the switching is an information terminal in an environment where the use of radio waves is restricted. 20 is determined based on the presence or absence of a predetermined operation performed on the control unit 20.

  If it is determined in S21 that switching to the non-communication mode is necessary, the information terminal 20 sets the communication mode to the non-communication mode (S22), and notifies the activity meter 10 of the set communication mode (S23). ). The activity meter 10 stops communication in response to the notification of the communication mode (S24).

  In the non-communication mode, the activity meter 10 determines whether it is necessary to return communication in parallel with the measurement of the activity state (S25). As described with reference to FIG. 4, the return of communication means a transition from the non-communication mode to the normal communication mode or the first power saving mode, and the necessity of the communication return depends on a change in the activity state of the user. Based on the determination.

  If it is determined in S25 that it is necessary to return communication, the activity meter 10 establishes communication with the information terminal 20 (S26), and transmits a communication return request to the information terminal 20 (S27). In response to the return request, the information terminal 20 sets the communication mode before the communication is stopped (S28), and notifies the activity meter 10 of the set communication mode (S29). The activity meter 10 resumes the transmission of activity data at the communication frequency determined by the communication mode (S30). Thereby, communication can be restored according to a change in the activity state of the user without providing a manual switch in the activity meter 10.

  As described above, according to the activity amount measuring system 1 according to the embodiment of the present invention, the communication frequency is set based on the activity state of the user, and the activity amount data is transmitted to the activity meter 10 with the set communication frequency. Can be made. As a result, the communication frequency can be switched according to the activity state of the user without providing the activity meter 10 with a manual switch. As a result, power saving, downsizing, and cost reduction of the activity meter 10 can be achieved. Can be planned.

Thereby, the activity meter 10 sets the measurement mode based on the activity state of the user, the information terminal 20 sets the communication frequency according to the set measurement mode, and the activity transmitted at the set communication frequency. Quantity data can be received.

  In addition, after the communication frequency is set to 0, the activity meter 10 changes the activity state of the user from the state in which the activity associated with the daily activity is performed to the state in which the operation exceeding the activity associated with the daily activity is performed. May be requested to the information terminal 20 to return communication. In addition, the operation | movement accompanying a living activity means the operation | movement accompanying daily living activities, such as a housework and a desk work, for example, The operation | movement exceeding the operation | movement accompanying a living activity is a predetermined amount of walking or the activity meter 10 for example.
