<Configuration example of wearable device>
FIG. 1 is an explanatory diagram illustrating an example of a configuration of a wearable device 10 according to an embodiment.

  As shown in FIG. 1, the wearable device 10 includes an activity amount measuring unit 11, a wireless communication unit 12, a data identification unit 13, an identification ID table storage unit 14, a time synchronization unit 15, a data correction unit 16, and a correction data storage unit. 17, a received data storage unit 18, and a data input / output unit 19.

  The activity amount measuring unit 11 measures the activity amount in the wearer of the wearable device 10. The wireless communication unit 12 constituting the data processing unit performs wireless communication with a vital sensor (not shown). The wireless communication is short-range wireless communication such as Bluetooth (Bluetooth). The vital sensor that performs wireless communication with the wearable device 10 is, for example, a weight scale, a blood pressure monitor, a blood glucose level measuring device, or a pulse oximeter. The pulse oximeter measures, for example, arterial oxygen saturation and pulse rate.

  The data identification unit 13 constituting the data processing unit searches the identification ID table storage unit 14 and identifies vital data received by the wireless communication unit 12. The identification ID table storage unit 14 serving as a correction information storage unit and an address storage unit stores identification ID data.

  The identification ID data includes profile data, type data, address data, a correction flag, and the like. The profile data, type data, address data, and correction flag of the measurer are associated with the device ID.

  The device ID is an identification number assigned to each vital sensor. The profile data is data indicating the profile of the measurer. The type data is the type of the vital sensor that measured the vital data. The address data is a transmission destination address of vital data. The correction flag, which is correction information, is a flag for determining whether or not correction processing is necessary for the received vital data.

  When the wireless communication unit 12 receives vital data, the time synchronization unit 15 serving as a clock unit synchronizes with the current time of the electronic terminal 40 shown in FIG. 2 connected to the wearable device 10 and receives the vital data. It is given as time. Here, the electronic terminal 40 is a smartphone or a personal computer.

  The data correction unit 16 configuring the data processing unit refers to the correction data stored in the correction data storage unit 17 and corrects the vital data. The data input / output unit 19 serving as a data communication unit is connected to the electronic terminal 40 and exchanges data with the electronic terminal 40.

  The wearable device 10 and the electronic terminal 40 are connected by wireless communication in the same manner as the vital sensor. The wireless communication may be a short-range wireless communication such as Bluetooth or a wireless network such as a wireless LAN (Local Area Network).

<Data communication example>
FIG. 2 is an explanatory diagram showing an example of data communication by the wearable device 10 of FIG. FIG. 2 shows an example in which the wearable device 10, the weight scale 30, and the sphygmomanometer 31 are used as vital sensors.

  As shown in the figure, the wearable device 10 is connected to a weight scale 30 and a sphygmomanometer 31 by wireless communication. The wearable device 10 is also connected to the electronic terminal 40 by wireless communication.

  The electronic terminal 40 is connected to an Internet line 41, and a weight scale server 42, a sphygmomanometer server 43, and an activity amount server 44 are connected to the Internet line 41, respectively.

  The weight scale server 42 accumulates the weight data measured by the weight scale 30. The sphygmomanometer server 43 accumulates blood pressure data measured by the sphygmomanometer server 43. The activity amount server 44 accumulates the activity amount measured by the wearable device 10.

  Next, the flow of vital data measured by the vital sensor will be described.

  The weight data measured by the weight scale 30 and the blood pressure data measured by the sphygmomanometer 31 are respectively transmitted to the wearable device 10 connected by wireless communication. The wearable device 10 assigns and stores the identification ID described above when receiving the weight data and blood pressure data. The wearable device 10 measures an activity amount, and stores the measured activity amount data with an identification ID.

  Subsequently, when the wearable device 10 is connected to the electronic terminal 40 by wireless communication, the activity amount data, the weight data, and the blood pressure data stored in the wearable device 10 are transmitted to the electronic terminal 40, respectively.

  The electronic terminal 40 determines a destination address based on the identification IDs assigned to the activity data, the weight data, and the blood pressure data, and the weight data is stored in the weight scale server 42 and the blood pressure data is stored in the blood pressure monitor server 43. The activity amount server 44 transmits the activity amount data.

<Operation example of wearable device>
Subsequently, the operation of the wearable device 10 will be described with reference to FIGS.

  FIG. 3 is a flowchart showing an example of the operation in the wearable device 10 of FIG.

  First, in the wearable device 10, the wireless communication unit 12 receives vital data measured by another vital sensor (step S101). Specifically, the wireless communication unit 12 receives the weight data transmitted from the weight scale 30.

  As described above, wireless communication such as Bluetooth is used for this wireless communication. Further, when transmitting the weight data, the weight scale 30 transmits the measured weight data with a device ID indicating that the measured vital sensor is a weight scale.

  Subsequently, time synchronization is performed in which the current time is added to the weight data received by the wireless communication unit 12 (step S102). In this time synchronization, when the weight data received by the wireless communication unit 12 is output to the data identification unit 13, the time synchronization unit 15 captures and captures the current time from the electronic terminal 40 that is in wireless communication with the wearable device 10. The current time is added to the weight data output to the data identification unit 13 as the measurement time.

  Thus, the measurement time can be managed with high accuracy by synchronizing the received data with the time of the electronic terminal 40 to obtain the measurement time.

  Subsequently, the data identification unit 13 performs data identification (step S103). In this data identification, the data identification unit 13 searches the identification ID table storage unit 14 based on the device ID added to the weight data, and from the identification ID table storage unit 14, profile data, type data, transmission The destination address and the presence / absence of a correction flag are acquired.

  In the case of weight data, the type data is data indicating that it is the weight scale 30, and the transmission destination address is an address for accessing the weight scale server 42.

  Thereafter, the data identification unit 13 adds the profile data, type data, transmission destination address, and presence / absence of the correction flag acquired in the process of step S103 to the received vital data and outputs them to the data correction unit 16.

  Upon receiving data from the data identification unit 13, the data correction unit 16 determines whether data correction is necessary (step S104). In the processing of step S104, the data correction unit 16 checks whether or not the input vital data has a correction flag, and determines that data correction is necessary if there is a correction flag. If there is no correction flag, it is determined that data correction is unnecessary.

  If it is determined that data correction is necessary, the data correction unit 16 searches the correction data storage unit 17 based on the type data, acquires the corresponding correction data, and acquires vital data based on the correction data. Correction is performed (step S105).

  When measuring the weight with the weight scale 30, if the weight is measured with clothes on, the value becomes larger than the actual weight. Therefore, when body weight is always measured while wearing clothes, the weight for clothes is set as correction data and set in the correction data storage unit 17.

  For example, the correction data is input from the electronic terminal 40 when the wearable device 10 and the electronic terminal 40 are connected by wireless communication. The correction data input from the electronic terminal 40 is stored in the correction data storage unit 17 via the data input / output unit 19.

  For example, when “−0.5 kg” is set as the correction value of the weight data, if the weight data transmitted from the weight scale 30 is 60 kg, the weight data corrected by the data correction unit 16 is 59.5 kg. Become. Thus, since the vital data transmitted from the vital sensor is corrected, the accuracy of the vital data can be improved.

  Subsequently, the weight data corrected in the process of step S105 or the weight data without the correction flag in the process of step S104 is stored in the reception data storage unit 18 serving as a data storage unit. At this time, the profile data added to the weight data, the type data, the transmission destination address, and the correction flag are also stored.

  Although the weight data is mainly described here, the blood pressure data measured by the sphygmomanometer 31 is similarly processed after the processing of steps S101 to S105, and then blood pressure data, type data, transmission destination address, The correction flag is stored in the received data storage unit 18.

  The same applies to the activity amount data measured by the activity amount measuring unit 11. However, since the activity amount measuring unit 11 is provided in the wearable device 10, it is not necessary to transmit measurement data. Therefore, after the processing of steps S102 to S105 is performed, the activity amount data, the type data, the transmission destination address, and the correction flag are stored in the reception data storage unit 18.

  Thereafter, the data input / output unit 19 extracts the measurement data stored in the received data storage unit 18 and transmits it to the electronic terminal 40 in a lump (step S106). Thereby, all vital data can be transmitted to the electronic terminal 40 by one communication. The electronic terminal 40 transmits the input measurement data via the Internet line 41.

  For example, in the case of weight data, the electronic terminal 40 accesses the weight scale server 42 based on the transmission destination address added to the weight data, and transmits the weight data to the weight scale server 42. The weight scale server 42 manages the weight data based on the profile data added to the weight data.

  In the case of blood pressure data, the blood pressure monitor server 43 is accessed based on the transmission destination address added to the blood pressure data, and the blood pressure data is transmitted to the blood pressure monitor server 43. Similarly, in the case of activity amount data, the activity amount server 44 is accessed based on the transmission destination address added to the activity amount data, and the activity amount data is transmitted to the activity amount server 44.

  The information on the transmission destination address may be stored in a memory unit such as a data storage unit (not shown) of the electronic terminal 40 instead of being stored in the identification ID table storage unit 14.

  In this case, if the wearable device 10 is, for example, weight data, the type data added to the weight data is transmitted to the electronic terminal 40. The electronic terminal 40 searches the memory unit included in the electronic terminal 40 from the type data added to the weight data, and acquires the transmission destination address of the received weight data.

  Thereafter, the electronic terminal 40 accesses the weight scale server 42 based on the acquired transmission destination address, and executes a process of storing weight data in the weight scale server 42.

  As described above, vital data measured by a plurality of different vital sensors can be collectively transmitted to various servers. As a result, the work of individually transmitting data for each vital sensor can be eliminated, and convenience can be improved.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  In addition, this invention is not limited to above-described embodiment, Various modifications are included. For example, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to one having all the configurations described.

  Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. . In addition, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
