As shown in FIG. 1, the information communication system 100 includes a diver-side device 1 possessed by a diver, an administrator-side device 2 possessed by an administrator, and a server 3 provided remotely. The diver-side device 1, the administrator-side device 2, and the server 3 are communicably connected via a network 200 such as the Internet.

[0011] The diver-side device 1 is a device that measures and records the diver's state and position information, and is, for example, a smartwatch worn on the diver's arm. The administrator-side device 2 is a device that plays the role of a control tower for checking the diver's state and position information, and is, for example, a smartphone or tablet terminal carried by an administrator. The server 3 is a device that realizes a diving communication function in cooperation with the diver-side device 1 and the administrator-side device 2, and is a cloud server equipped with a processor such as a CPU and a memory. The diving communication function is a function for sharing information between the diver-side device 1 and the administrator-side device 2, which is realized by executing an application program.

[0012] FIG. 2 is a control block diagram of the information communication system 100 according to Embodiment 1. As shown in FIG. 2, the diver-side device 1 includes a control unit 11, a storage unit 12, a communication unit 13, an operation display unit 14, a sensor unit 15, and a timing unit 16.

[0018] The timing unit 16 is a timer, and measures time information indicating the current time, dive time which is the elapsed time since the start of diving (entry), etc., and outputs them to the control unit 11.

[0019] The administrator-side device 2 includes a control unit 21, a storage unit 22, a communication unit 23, and an operation display unit 24. The control unit 21 is composed of a processor such as a CPU or GPU, a processing circuit such as an ASIC or FPGA, or both. The control unit 21 implements the diving communication function by executing the application program stored in the storage unit 22. Specifically, the control unit 21 receives notifications regarding the entry and exit of the diver-side device 1 and displays them on the operation display unit 24. Also, the control unit 21 receives a display screen such as a screen including the entry information, exit information, and current position information of the diver-side device 1 from the server 3 and displays it on the operation display unit 24.

[0020] The storage unit 22 is, for example, a non-volatile memory such as a ROM or a flash memory, or a volatile memory such as a RAM. The storage unit 22 stores the application program executed by the control unit 21 and various data used for the execution of the application program.

[0021] The communication unit 23 communicates with the server 3 via the network 200 and receives notifications regarding the entry and exit of the diver-side device 1, as well as various display screens, from the server 3. The communication unit 23 connects to the network 200 using mobile data communication, wireless LAN, satellite communication, Bluetooth (registered trademark), or the like.

[0022] The operation display unit 24 is, for example, a touch panel and displays the display screen and operation buttons in the diving communication function. The instruction content input to the operation display unit 24 is output to the control unit 21.

[0023] The server 3 includes a control unit 31, a storage unit 32, and a communication unit 33. The control unit 31 is composed of a processor such as a CPU or GPU, a processing circuit such as an ASIC or FPGA, or both. The control unit 31 manages information for the diving communication function and generates content by executing the program stored in the storage unit 32.

[0024] Specifically, the control unit 21 manages the login and setting information of the diver-side device 1 and the administrator-side device 2. Also, the control unit 21 stores information such as entry information, exit information, current position information, and diving logs received from the diver-side device 1 in the storage unit 32. Further, the control unit 31 generates various display screens in the diving communication function and provides them to the diver-side device 1 and the administrator-side device 2.

[0025] The storage unit 32 is, for example, a non-volatile semiconductor memory such as a ROM or flash memory, a volatile semiconductor memory such as a RAM, an SSD, or an HDD. The storage unit 32 stores the program executed by the control unit 21 and various data used for the execution of the program. Also, the storage unit 32 stores the login information and setting information of the diver-side device 1 and the administrator-side device 2, the entry information, exit information, current position information, and diving logs received from the diver-side device 1, and the display screen data displayed on the diver-side device 1 and the administrator-side device 2.

[0026] The communication unit 33 communicates with the diver-side device 1 and the administrator-side device 2 via the network 200, and receives entry information, exit information, current location information, and diving logs from the diver-side device 1. Further, the communication unit 33 transmits notifications regarding the entry and exit of the diver-side device 1 and a display screen to the administrator-side device 2. The communication unit 33 connects to the network 200 using mobile data communication, wireless LAN, satellite communication, Bluetooth (registered trademark), or the like.

[0027] Next, the flow of the diving communication function implemented in the information communication system 100 of the present embodiment will be described. The diving communication function is implemented by starting an application program and logging in on the diver-side device 1 and the administrator-side device 2, respectively. First, before diving, settings are made on the diver-side device 1 and the administrator-side device 2, respectively. On the diver-side device 1, settings for the sharing target (administrator-side device 2) that shares its own information are made, and on the administrator-side device 2, settings for the management target (diver-side device 1) are made.

[0028] FIG. 3 is an example of a setting screen 51 displayed on the diver-side device 1 according to Embodiment 1. As shown in FIG. 3, the setting screen 51 includes an icon setting unit 510, a name setting unit 511, a notification setting unit 512, a sharing setting unit 513, a sharing time setting unit 514, and a sharer setting unit 515.

[0029] The icon setting unit 510 sets icons such as a photo of the diver who is the owner of the diver-side device 1. The name setting unit 511 sets the name of the diver who is the owner of the diver-side device 1. The notification setting unit 512 sets whether to notify the sharing target person about the diver's entry and exit. The sharing setting unit 513 sets whether to share the diver's location information with the sharing target person. The sharing time setting unit 514 sets the time for sharing the diver's information, and for example, time unit settings such as 1 hour, 2 hours, etc. or day unit settings such as 1 day can be made. The sharer setting unit 515 sets the sharing target person with whom the diver's information is to be shared, and the name or account of the administrator-side device 2 is set.

[0030] Note that the setting of information sharing in the diver-side device 1 is performed when the diver is on the ground before diving. Also, the setting of information sharing may be performed using the diver-side device 1, or may be performed using a smartphone or tablet connected to the diver-side device 1. Note that the content set on the setting screen 51 is not limited to the above, and other settings may be made. For example, items to be recorded as a diving log may be set on the setting screen 51, or whether to delegate the setting of extending the information sharing time to the administrator-side device 2 may be set. By setting to delegate the setting of extending the information sharing time to the administrator-side device 2, the administrator-side device 2 can extend the information sharing time according to the situation, and information sharing can be continued even when the diver-side device 1 does not return to the boat, and the state of the diver can be confirmed.

[0031] Also in the administrator-side device 2, on the administrator's setting screen, the administrator's icon, name, and management target (diver-side device 1) are set. Note that the administrator-side device 2 may set a plurality of diver-side devices 1 as management targets. The content set by the diver-side device 1 and the administrator-side device 2 is transmitted to the server 3 and stored in the storage unit 32.

[0032] FIG. 4 is a diagram showing the operation flow of the information communication system 100 according to Embodiment 1. As shown in FIG. 4, first, an entry operation indicating the start of diving is performed by the diver (S1). Specifically, after setting information sharing, the diver wears the diver-side device 1 and enters the sea. At this time, the home screen 52 is displayed on the operation display unit 14 of the diver-side device 1. FIG. 5 is an example of the home screen 52 displayed on the diver-side device 1 according to Embodiment 1. As shown in FIG. 5, the home screen 52 includes a dive mode selection button 521, an underwater mode selection button 522, a map display button 523, and a diving log display button 524.

[0033] The dive mode selection button 521 is a button for selecting the dive mode and is selected when diving. The underwater mode selection button 522 is a button for selecting the underwater mode and is selected when checking the state underwater. The map display button 523 is a button for displaying the diver's position information. The diving log display button 524 is a button for displaying the diving log. When the diver presses the dive mode selection button 521 on the home screen 52, the dive screen 53 is displayed on the operation display unit 14 of the diver-side device 1.

[0034] FIG. 6 is an example of the dive screen 53 displayed on the diver-side device 1 according to Embodiment 1. As shown in FIG. 6, the dive screen 53 has a map 531 showing the diver's position information, an entry button 532, and an exit button 533. The entry button 532 is a button that is pressed by the diver before diving underwater. The exit button 533 is a button that is pressed when the diver surfaces from underwater. The entry operation in step S2 is performed by the diver pressing the entry button 532.

[0035] In addition, in FIG. 6, the entry button 532 and the exit button 533 are soft keys displayed on the operation display unit 14 of the diver-side device 1, but these buttons may be provided as hard keys. By providing the entry button 532 and the exit button 533 as hard keys, it becomes easier to operate even when the diver's hand or the operation display unit 14 is wet with water.

[0036] Returning to FIG. 4, when the diver performs an entry operation, the diver-side device 1 transmits the position information and time information at the time of entry as entry information to the server 3 (S2). The position information at the time of entry is acquired by the GPS sensor of the sensor unit 15, and the time information is acquired by the timekeeping unit 16. Then, the server 3 stores the entry information received from the diver-side device 1 in the storage unit 32 (S3), and notifies the administrator-side device 2 that the entry information of the diver-side device 1 has been stored (S4).

[0037] On the administrator-side device 2, a notification from the server 3 is displayed (S5). FIG. 7 is an example of the notification 240 displayed on the administrator-side device 2 according to Embodiment 1. As shown in FIG. 7, the notification 240 includes a message notifying that the diver's information has been updated. Further, the notification 240 may include the entry information of the diver-side device 1 (that is, the diver's position information and time information). The notification 240 is a push notification and is also displayed on the operation display unit 24 even when the diving communication function screen is not displayed on the administrator-side device 2. Thus, by displaying the notification 240 on the administrator-side device 2, the administrator can know in real time that the diver has entered.

[0038] Returning to FIG. 4, when the diver dives underwater, the diver-side device 1 automatically switches to the underwater mode, and a diving log is recorded based on the measurement data of the sensor unit 15 (S6). Here, the water pressure, water temperature, heart rate, etc. are measured by each sensor of the sensor unit 15 and stored in the storage unit 12 as a diving log together with the time information.

[0039] Further, a status screen 54 including the measurement data of the sensor unit 15 is displayed on the operation display unit 14 of the diver-side device 1. FIG. 8 is an example of the status screen 54 displayed on the diver-side device 1 according to the first embodiment. As shown in FIG. 8, the status screen 54 includes a water depth display unit 541, a dive time display unit 542, an NDL display unit 543, a water temperature display unit 544, and a heart rate display unit 545.

[0040] The current water depth (m) is displayed on the water depth display unit 541. The water depth is obtained from the water pressure measured by the sensor unit 15. The elapsed time since entry measured by the timer unit 16 is displayed on the dive time display unit 542. The no decompression limit (NDL), which is the time that one can stay at that water depth without the need for decompression stops, is displayed on the NDL display unit 543. The NDL is obtained from the water pressure and the dive time. The water temperature (°C) is displayed on the water temperature display unit 544, and the diver's heart rate (bpm) is displayed on the heart rate display unit 545. By looking at the status screen 54 displayed on the operation display unit 14 of the diver-side device 1, the diver can confirm his / her current status and the surrounding environment.

[0041] Returning to FIG. 4, when the diving is completed and the diver surfaces, an exit operation indicating the end of the diving is performed by the diver (S7). Specifically, when the diver surfaces, the diver-side device 1 automatically switches to the map mode, and the dive screen 53 shown in FIG. 6 is displayed on the operation display unit 14 of the diver-side device 1. Then, when the diver presses the exit button 533 on the dive screen 53, the exit operation is performed.

[0042] When the diver operates the exit, the diver-side device 1 transmits the position information and time information at the time of exit as exit information to the server 3 (S8). The position information at the time of exit is acquired by the GPS sensor of the sensor unit 15, and the time information is acquired by the timekeeping unit 16. Then, the server 3 stores the exit information received from the diver-side device 1 in the storage unit 32 (S9), and notifies the administrator-side device 2 that the exit information of the diver-side device 1 has been stored (S10). In the administrator-side device 2, the notification from the server 3 is displayed (S11). The notification 240 at this time is a push notification as in FIG. 7, and includes a message notifying that the diver's information has been updated. Further, the notification 240 may include the exit information of the diver-side device 1 (that is, the diver's position information and time information). Note that the diver-side device 1 may automatically transmit the exit information to the server 3 when the diver surfaces (that is, without the diver operating the exit).

[0043] Thereafter, the diver-side device 1 periodically transmits current position information including the current position information and time information to the server 3 (S12). In the server 3, the current position information received from the diver-side device 1 is stored in the storage unit 32 (S13). During the diving, the processes of steps S1 to S13 are executed each time the diver dives and surfaces.

[0044] The administrator-side device 2 can confirm the current position of the diver using the diving communication function. Specifically, the administrator-side device 2 requests the position information for confirming the current position of the diver (S14). When the server 3 receives the request for the position information from the administrator-side device 2, it generates a map screen 61 based on the current position information of the diver stored in the storage unit 32 and transmits it to the administrator-side device 2 (S15). The administrator-side device 2 displays the map screen 61 received from the server 3 on the operation display unit 24 (S16).

[0045] FIG. 9 is an example of a map screen 61 displayed on the administrator-side device 2 according to Embodiment 1. As shown in FIG. 9, the map screen 61 includes a map 611, icons 612 displayed within the map, and a diver information display section 613. On the map 611, icons 612 of one or more diver-side devices 1 set as management targets by the administrator-side device 2 are displayed. The positions of the respective icons 612 on the map 611 correspond to the latest position information of the respective diver-side devices 1. In the diver information display section 613, diver information of the diver-side devices 1 set as management targets by the administrator-side device 2 is displayed. The diver information includes the name, icon, entry information, and exit information of the diver. Note that the information displayed in the diver information display section 613 is not limited to the above. For example, when the icon in the diver information display section 613 is clicked, detailed information such as the emergency contact of the diver may be displayed.

[0046] By displaying the map screen 61 on the administrator-side device 2, the administrator does not need to check the information of individual divers one by one, and can easily grasp the current positions of a plurality of divers to be managed at a glance. As a result, it is possible to quickly take measures such as moving the boat to the current position of the diver. Note that on the administrator-side device 2, the map screen 61 may be displayed at an arbitrary timing, such as after the diver's entry and after the diver's exit. For example, when the server 3 notifies the administrator-side device 2 of the diver's entry or exit, the administrator-side device 2 may request the server 3 for position information. In this case, the server 3 generates the map screen 61 based on the entry information or the exit information and transmits it to the administrator-side device 2. The map screen 61 in this case includes a map 611, icons 612 displayed within the map, and a diver information display section 613, similar to FIG. 9. Also, the positions of the icons 612 on the map 611 in this case correspond to the position information at the time of entry or the position information at the time of exit of the respective diver-side devices 1.

[0047] Returning to FIG. 4, after the diving is completed and the diver has returned to the boat or home, the diver transmits the diving log stored in the storage unit 12 of the diver-side device 1 to the server 3 (S17). The server 3 stores the diving log received from the diver-side device 1 in the storage unit 32 (S18). The diver-side device 1 and the administrator-side device 2 can check the diving log stored in the server 3.

[0048] For example, when the diving log of the diver is requested in the administrator-side device 2 (S19), the server 3 generates a log screen 62 based on the diving log of the diver stored in the storage unit 32 and transmits it to the administrator-side device 2 (S20). The administrator-side device 2 displays the log screen 62 received from the server 3 on the operation display unit 24 (S21). Note that the diver-side device 1 may synchronize with the administrator-side device 2 via a wireless LAN or Bluetooth (registered trademark) and directly transmit the diving log stored in the storage unit 12 to the administrator-side device 2.

[0049] FIG. 10 is an example of the log screen 62 displayed on the administrator-side device 2 according to the first embodiment. As shown in FIG. 10, the log screen 62 includes the diver's name 621, the diving location 622, the diving log 623, and the dive graph 624. The diving log 623 includes the entry time, exit time, dive time, maximum depth, water temperature, and the like. Also, the dive graph 624 is a graph of the time-series data of the measurement data stored as the diving log. In the diver-side device 1 as well, by requesting the diving log, the log screen 62 of FIG. 10 can be displayed. Thereby, the diving log can be checked after diving and can be used for future diving plans and the like.

[0050] As described above, according to the information communication system 100 of the present embodiment, in the administrator-side device 2, by sharing the entry information, exit information, current position information, etc. of the diver-side device 1, the situation and current position of the diver can be grasped. Thereby, even when the diver's surfacing position deviates from the planned position, etc., the diver can be quickly picked up, and the safety of the diver can be improved.

[0051] The above is the description of the embodiment. However, the above embodiment can be appropriately modified. For example, in the above embodiment, in the diver-side device 1, one administrator-side device 2 is set as the sharing target, but a plurality of administrator-side devices 2 may be set as the sharing targets. For example, family members or friends may be registered as sharing targets. In this case, the administrator-side device 2 is a smartphone or tablet terminal owned by a family member or friend. Thereby, family members and friends who are in a distant place can also know the situation of the diver. Also, the diver-side device 1 may be configured to be able to communicate with an external device other than the server 3 and the administrator-side device 2. For example, it may be configured to be able to send a rescue request from the diver-side device 1 to the external device.

[0052] Also, in the above embodiment, the current position of the diver-side device 1 can be known from the administrator-side device 2, but the current position of the administrator-side device 2 may be known from the diver-side device 1. FIG. 11 is a diagram showing the operation flow of the information communication system 100 according to Modification 1. The process shown in FIG. 11 can be carried out at any timing of the process shown in FIG. 4. In this modification, it is assumed that the administrator-side device 2 has a GPS sensor and a timing unit and can acquire its own position information and time information.

[0053] As shown in FIG. 11, the administrator-side device 2 periodically or in response to a request from the driver-side device 1 transmits current position information including the current position information and time information to the server 3 (S31). The server 3 stores the current position information received from the administrator-side device 2 in the storage unit 32 (S32). Then, in the driver-side device 1, the position information of the administrator-side device 2 is requested (S33). The server 3 generates a map screen 55 based on the current position information of the administrator-side device 2 stored in the storage unit 32 and transmits it to the driver-side device 1 (S34). The map screen 55 received from the server 3 is displayed on the operation display unit 14 of the driver-side device 1 (S35).

[0054] FIG. 12 is an example of the map screen 55 displayed on the driver-side device 1 according to the first modification. As shown in FIG. 12, the map screen 55 includes a map 551, a driver icon 552 displayed in the map, and an administrator icon 553. In addition to the driver icon 552, the map 551 displays the icon 553 of the administrator-side device 2 set by the driver-side device 1 as a sharing target. The positions of the icons on the map 551 correspond to the latest position information of the driver-side device 1 and the administrator-side device 2. By displaying the map screen 55 on the driver-side device 1, the driver can know the position of the boat where the administrator is located and can take corresponding actions such as heading towards the boat even if they get separated.

[0055] As another modification, in the above embodiment, on the map screen 61 displayed on the administrator-side device 2, the current position of the diver-side device 1 is displayed, but the present invention is not limited to this. FIG. 13 is an example of a map screen 63 displayed on the administrator-side device 2 according to Modification 2. As shown in FIG. 13, the map screen 63 may include the history of the exit information of the diver-side device 1. FIG. 13 shows an example in which entry and exit are repeated three times in the diver-side device 1. The map screen 63 includes a map 631, a plurality of icons 632 of the same diver, and a diver information display unit 633 that displays diver information. The positions of the plurality of icons 632 on the map 631 respectively correspond to the position information at the exit of the first log L1, the position information at the exit of the second log L2, and the position information at the exit of the third log L3. The diver information includes the diver's name, icon, and entry information and exit information in each of the logs L1 to L3. By performing such a display, the movement route of the diver can be traced and the current position can be estimated.

[0056] Furthermore, in the above embodiment, the diver-side device 1 is configured to transmit both entry information and exit information, but the diver-side device 1 may transmit at least one of the entry information and the exit information. For example, since the position at the time of the diver's entry is the start position of the diving and is often grasped by the administrator, the diver-side device 1 may transmit only the exit information.

[0057] Also, in the above embodiment, the diver-side device 1 and the administrator-side device 2 are configured to perform cloud communication via the server 3, but the diver-side device 1 and the administrator-side device 2 may communicate directly without going through the server 3. In this case, either the diver-side device 1 or the administrator-side device 2, or both, shall perform the functions of the server 3.
