Description

  The present invention relates to a communication device, a communication method, and a program for controlling the communication method.

  Conventionally, it has been proposed to wear a wearable device (second terminal) with a built-in biosensor (for example, Patent Document 1). It has also been proposed that this wearable device wirelessly transmits biological information detected by a biological sensor to an external device (first terminal) such as a portable terminal, and causes the external device to display and record the biological information.

  By the way, a user wearing a wearable device may want to replace an external device that transmits biometric information. For example, when driving an automobile, there is a case where it is desired to display biometric information on an in-vehicle device instead of an in-vehicle device such as a navigation device installed in the automobile from a portable terminal.

  However, many wearable devices currently in circulation can only perform one-to-one wireless communication. For this reason, conventionally, it has been necessary for the user to manually operate the wearable device to switch the connection destination from the portable terminal to the vehicle-mounted device, which is troublesome.

The connection unit 37 includes a built-in radio wave intensity detection unit that detects the radio wave intensity received from the wearable device 10 or the portable terminal 20, and outputs the detected radio wave intensity to the control unit 31.

  Next, the operation of the communication system 1 configured as described above will be described below with reference to the flowcharts of FIGS. Here, as an example, it is assumed that the connection unit 37 of the navigation device 30 includes a BT module. First, the user performs BT initial registration so that the navigation device 30, the wearable device 10, and the mobile terminal 20 can be wirelessly connected. That is, the identification information (ID) of the wearable device 10 and the portable terminal 20 is recorded in the storage unit 33 of the navigation device 30 as a slave device. In addition, the ID of the navigation device 30 is recorded as a master device in the memory (not shown) of the wearable device 10 and the memory 21 of the mobile terminal 20.

  This BT initial registration may be performed in accordance with a general pairing procedure. For example, when the user operates the navigation device 30, the wearable device 10, and the mobile terminal 20 to set each to the pairing mode, the ID is automatically set. Exchange and registration. When this BT initial registration is performed, the navigation device 30, the wearable device 10, and the mobile terminal 20 can be automatically wirelessly connected as long as they are within an area where they can communicate with each other.

  Next, the user operates the navigation device 30 to perform priority registration for registering the ID of the wearable device 10 as a priority device that prioritizes connection. First, after performing the BT initial registration, the navigation device 30 and the wearable device 10 are wirelessly connected. In this state, the user operates the operation unit 34 of the navigation device 30 to cause the control unit 31 of the navigation device 30 to execute the priority registration process shown in FIG.

  In the priority registration process, the control unit 31 displays the ID of the device wirelessly connected to the display unit 35 (step S11). Thereafter, when the user operates the operation unit 34 of the navigation device 30 and selects the ID of the wearable device 10 that is to be registered as the priority device (Y in step S12), the control unit 31 stores the selected ID as the priority device. After storing in 33 (step S13), the process is terminated.

  In addition, the user installs a cutting application in the mobile terminal 20 in advance. Then, the user operates the mobile terminal 20 to associate the ID of the navigation device 30 with the cutting application. First, after performing the initial registration, the navigation device 30 and the mobile terminal 20 are wirelessly connected. In this state, the user operates the mobile terminal 20 to start up the cutting application installed on the mobile terminal 20.

  Thereafter, the user operates the mobile terminal 20 to execute the linking process illustrated in FIG. 4 of the cutting application. The control unit 24 displays the ID of the device wirelessly connected to the display unit 22 (step S21). After that, when the user operates the mobile terminal 20 and selects the ID of the navigation device 30 that the user wants to associate (Y in step S22), the control unit 24 stores the selected ID in the memory 21 as a device associated with the cutting application. (Step S23). Thereafter, the control unit 24 terminates the associating process after executing the cutting process of the cutting application described later.

  The wearable device 10 and the mobile terminal 20 are paired with each other. The wearable device 10 is worn by a user, and when the user is outside the vehicle, the wearable device 10 and the portable terminal 20 are wirelessly connected, and biological information is periodically transmitted from the wearable device 10 to the portable terminal 20. An ID of the wearable device 10 is also added to this biometric information.

  While the mobile terminal 20 is wirelessly connected to the wearable device 10, a disconnection application is started and the disconnection process shown in FIG. 5 is executed. In the disconnection process, the control unit 24 of the mobile terminal 20 is in a waiting state for a disconnection command while the disconnection command is not received from the navigation device 30 associated with the disconnection application (N in step S42) (step S41). ). In the waiting state for the disconnection command, the mobile terminal 20 maintains a wireless connection with the wearable device 10.

  On the other hand, the control unit 31 of the navigation device 30 in the vehicle always executes a connection process as shown in FIG. First, the control unit 31 monitors the radio wave received by the connection unit 37 (step S31) until the radio wave transmitted from the wearable device 10 registered as the priority device is received (Y in step S32). When the user wearing the wearable device 10 and having the mobile terminal 20 enters the communication area of the connection unit 37 of the navigation device 30 to get into the vehicle, the navigation device 30 and the mobile terminal 20 are wirelessly connected. On the other hand, the wearable device 10 is already wirelessly connected to the mobile terminal 20 and thus cannot be wirelessly connected to the navigation device 30, but the connection unit 37 of the navigation device 30 can receive radio waves transmitted from the wearable device 10. .

  At this time, the control unit 31 of the navigation device 30 determines that the radio wave from the wearable device 10 registered as the priority device is received from the ID of the wearable device 10 included in the received radio wave (Y in step S32). The connection part 37 is controlled and a disconnection command is transmitted with respect to the portable terminal 20 (step S33). This disconnection command includes the ID of the navigation device 30 and the disconnection time.

  When the control unit 24 of the portable terminal 20 receives the disconnection command from the associated navigation device 30 (Y in step S42), the control unit 24 controls the connection unit 23 to disconnect the wireless connection for the disconnection time included in the disconnection command. (Step S43), the process returns to Step S41. In step S43, the control unit 24 may disconnect the wireless connection with all the wirelessly connected devices, or when the wearable device 10 is registered in advance as a priority device, etc. Only the wireless connection may be disconnected.

  The wearable device 10 automatically searches for a communication partner when the wireless connection with the mobile terminal 20 is disconnected. The control unit 31 of the navigation device 30 transmits a connection request to the wearable device 10 after transmitting a disconnection command (step S33) (step S34). The wearable device 10 receives the connection request from the navigation device 30 and wirelessly connects to the navigation device 30. The wearable device 10 transmits biometric information in response to a command from the navigation device 30.

  When the navigation device 30 receives the biological information, the navigation device 30 displays it on the display unit 35 or stores it in the storage unit 33. Further, the navigation device 30 may perform a route search based on the biological information.

  According to the embodiment described above, when the control unit 31 of the navigation device 30 receives the radio wave of the wearable device 10, that is, when the distance between the navigation device 30 and the wearable device 10 is a communicable distance, automatic Thus, it is possible to disconnect the wireless connection between the mobile terminal 20 and the wearable device 10 by transmitting a disconnection command to the mobile terminal 20. Since the wearable device 10 and the navigation device 30 are wirelessly connected while being disconnected, the connection destination of the wearable device 10 can be automatically switched from the portable terminal 20 to the navigation device 30. This eliminates the need to manually switch the connection destination of the wearable device 10.

  Further, according to the above-described embodiment, the wearable device 10 performs a one-to-one wireless connection, and when the wireless connection with the communication partner is disconnected, the wearable device 10 automatically searches for the communication partner and connects with the communication partner. Thereby, when the wireless connection with the portable terminal 20 is disconnected, the wearable device 10 automatically searches for a communication partner and connects to the navigation device 30.

  Further, according to the above-described embodiment, the disconnection instruction is an instruction to disconnect the wireless connection between the mobile terminal 20 and the wearable device 10 for a predetermined disconnection time. As a result, the portable terminal 20 disconnects the wireless connection with the wearable device 10 for a predetermined disconnection time, and then becomes wirelessly connected to the wearable device 10 again, so that the wearable device 10 leaves the navigation device 30 and the like. When the wireless connection between the wearable device 10 and the navigation device 30 is disconnected, the wearable device 10 automatically searches for a communication partner and connects to the portable terminal 20 again.

  In addition, according to the Example mentioned above, when the distance of the wearable apparatus 10 and the navigation apparatus 30 existed in the communication area, the navigation apparatus 30 transmitted the cutting command, However, it is not restricted to this. . For example, the control unit 31 of the navigation device 30 functions as an approach detection unit, takes in the radio wave intensity of the wearable device 10 from the connection unit 37 (according to the distance between the wearable device 10 and the navigation device 30), and wears the wearable device. It is detected whether 10 is approaching.

  Then, the control unit 31 may cause the wireless terminal 20 to disconnect the wireless connection between the wearable device 10 and the mobile terminal 20 by transmitting a disconnection command to the mobile terminal 20 based on the approach detection result. Based on the approach detection result, the control unit 31 may transmit a disconnection command when it is detected that the wearable device 10 is approaching, or does the control unit 31 transmit a disconnection command? The approach detection result may be used as one of the determinations of no. Thereby, when the wearable device 10 approaches the navigation device 30, the connection destination of the wearable device 10 can be automatically switched from the portable terminal 20 to the navigation device 30.

  In addition, the control unit 31 functions as a boarding detection unit, detects that the user wearing the wearable device 10 has entered the vehicle, and transmits a disconnection command when it is detected that the user has entered the vehicle. It may be. Thereby, when the user with the wearable device 10 gets into the vehicle, the connection destination of the wearable device 10 can be automatically switched from the portable terminal 20 to the navigation device 30.

  As an example of this boarding detection, the following can be considered. For example, when the approach of the wearable device 10 is detected by the approach detection, the control unit 31 detects that the user has entered the vehicle when the opening / closing of the vehicle door or the seating by the seating sensor is detected. You may do it. Further, it may be detected from the radio wave intensity that the user has entered the vehicle when the distance from the wearable device 10 is within a predetermined range. Thereby, it can detect that the user with the wearable apparatus 10 got into the vehicle correctly.

  Moreover, although embodiment mentioned above demonstrated the 1st terminal as the portable terminals 20, such as a smart phone and a tablet, it is not restricted to this. The first terminal may be any terminal that can be wirelessly connected to the second terminal (wearable device 10) and the communication device (navigation device 30).
