Description

Technical Field

[0001] The present disclosure relates to a technology for assisting in guiding a user's movement.

Background Art

[0002] There is a technology for providing a route to a user according to the user's purpose. For example, Patent Document 1 describes displaying a route to a destination according to traffic conditions for a vehicle in which a user rides.

[0003] For example, in the event of a disaster, it is assumed that evacuation guidance is provided to the user. In this case, the user may not be able to grasp in advance where to move. In the technology of Patent Document 1, it is necessary for the user to grasp the destination in advance. Therefore, it is difficult to apply the technology of Patent Document 1 when there is a possibility that the user does not grasp the destination in advance, such as during a disaster.

[0004] On the other hand, Patent Document 2 describes that when a disaster occurs, if a communication terminal owned by a user exists within the communication range of an access point, a route from the access point to a shelter is transmitted to the communication terminal and the route is displayed on the communication terminal.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In the technology of Patent Document 2, a route to an evacuation shelter as the destination is displayed on a map. However, the technology of Patent Document 2 assumes that the user can correctly understand the map. For example, if the location where a disaster has occurred is a place where the user has no sense of direction, the user may not know how to read the map or may misjudge the moving direction. In such a case, it may not be possible to quickly guide the user to the evacuation shelter.

[0007] The present disclosure has been made in view of the above problems, and one of the objectives is to provide a guidance support system or the like that can appropriately guide a user.

Means for Solving the Problems

[0008] The guidance support system according to one aspect of the present disclosure includes a specifying means for specifying progress instruction information including information on the direction in which the slave unit device should move according to a combination of the identification information of the one master unit device when the slave unit device enters the communication range of the one master unit device and the identification information of another master unit device having a communication range in which the slave unit device existed before entering the communication range, and an output means for outputting the progress instruction information in the slave unit device.

[0009] The master unit device according to one aspect of the present disclosure includes a specifying means for specifying progress instruction information including information on the direction in which the slave unit device should move according to a combination of the identification information of the self-device when the slave unit device enters the communication range of the self-device and the identification information of another master unit device having a communication range in which the slave unit device existed before entering the communication range.

[0010] The slave unit device according to one aspect of the present disclosure includes an output means for outputting progress instruction information including information on the direction in which the slave unit device should move, which is specified according to a combination of the identification information of one master unit device having the communication range into which the self-device has entered and the identification information of another master unit device having a communication range in which the self-device existed before entering the communication range.

[0011] According to one aspect of the present disclosure, a guidance support method, when a slave unit device enters a communication range of a master unit device, specifies progress instruction information including information on a direction in which the slave unit device should move according to a combination of the identification information of the master unit device and the identification information of another master unit device having a communication range in which the slave unit device existed before entering the communication range, and outputs the progress instruction information in the slave unit device.

[0012] According to one aspect of the present disclosure, a program causes a computer to execute a process of specifying progress instruction information including information on a direction in which a slave unit device should move according to a combination of the identification information of the master unit device and the identification information of another master unit device having a communication range in which the slave unit device existed before entering the communication range, when the slave unit device enters the communication range of the master unit device, and a process of outputting the progress instruction information in the slave unit device.

MODE FOR CARRYING OUT THE INVENTION

[0015] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0016] <First Embodiment> The outline of the guidance support system according to the first embodiment will be described.

[0017] FIG. 1 is a block diagram showing an example of the functional configuration of a guidance support system 1000 according to the first embodiment. As shown in FIG. 1, the guidance support system 1000 includes a specifying unit 1100 and an output unit 1200. Note that the specifying unit 1100 and the output unit 1200 may be independent devices connected to each other via a communication network.

[0018] Assume that there are a slave station device and a master station device that can communicate with each other. At this time, the specifying unit 1100 specifies progress instruction information including information on the direction in which the slave station device should move. For example, when the slave station device enters the communication range of the master station device, the specifying unit 1100 acquires identification information of the master station device having the communication range. Here, the identification information is information for identifying the master station device. Also, for example, the specifying unit 1100 acquires identification information of another master station device having a communication range in which the slave station device existed before entering the communication range. Then, the specifying unit 1100 specifies progress instruction information including information on the direction in which the slave station device should move, for example, according to the combination of the acquired identification information. At this time, the specifying unit 1100 reads out, for example, predetermined information in which the combination of the identification information and the direction information are associated. The direction information is, for example, information on the direction in which the slave station device should move from the communication range in order to reach the destination. The specifying unit 1100 specifies, for example, the direction information corresponding to the combination of the acquired identification information as the progress instruction information based on the predetermined information. Note that the predetermined information is, for example, previously possessed by the guidance support system 1000.

[0019] In this way, when the slave unit device enters the communication range of one master unit device, the specific unit 1100 specifies progress instruction information including information on the direction in which the slave unit device should move, according to the combination of the identification information of the one master unit device and the identification information of another master unit device that had the communication range before the slave unit device entered the communication range. The specific unit 1100 is an example of a specifying means.

[0020] The output unit 1200 outputs the progress instruction information in the slave unit device. The output unit 1200 is an example of an output means.

[0021] Next, an example of the operation of the guidance support system 1000 will be described with reference to FIG. 2. In the present disclosure, each step of a flowchart or a sequence diagram is represented using a number assigned to each step, such as "S1".

[0022] FIG. 2 is a flowchart for explaining an example of the operation of the guidance support system 1000. When the slave unit device enters the communication range of one master unit device, the specific unit 1100 specifies progress instruction information including information on the direction in which the slave unit device should move, according to the combination of the identification information of the one master unit device and the identification information of another master unit device that had the communication range before the slave unit device entered the communication range (S1). Then, the output unit 1200 outputs the progress instruction information in the slave unit device (S2).

[0023] In this way, when the slave unit device of the guidance support system 1000 of the present disclosure enters the communication range of one master unit device, the guidance support system 1000 specifies progress instruction information including information on the direction in which the slave unit device should move, according to the combination of the identification information of the one master unit device and the identification information of another master unit device that had the communication range before the slave unit device entered the communication range. Then, the guidance support system 1000 outputs the progress instruction information in the slave unit device 200. With this configuration, the guidance support system 1000 of the present disclosure can appropriately provide the direction in which to move, according to, for example, the route along which the user who holds the slave unit device 200 has moved. That is, the guidance support system 1000 of the present disclosure can appropriately guide the user.

[0024] [Another Example of the Guidance Support System 1000] Next, another example of the guidance support system 1000 of the present disclosure will be described in detail. FIG. 3 is a diagram schematically showing the configuration of another example of the guidance support system 1000 according to the first embodiment. Specifically, the example of the configuration shown in FIG. 3 is an example in which the guidance support system 1000 in FIG. 1 is applied to a communication system having a master station device and a slave station device. As shown in FIG. 3, the guidance support system 1000 includes master station devices 100-1, 100-2, ···, 100-n (n is a natural number of 2 or more) and a slave station device 200. Each of the master station devices 100-1, 100-2, ···, 100-n and the slave station device 200 can be communicably connected. Also, the master station devices 100-1, 100-2, ···, 100-n may be communicably connected to each other. In this specification, when the master station devices 100-1, 100-2, ···, 100-n are not distinguished, they are also referred to as the master station device 100. The broken line portions in FIG. 3 indicate the communication ranges of the respective master station devices 100.

[0025] The master station device 100 is, for example, a base station, but is not limited to this example. The master station device 100 may be a device that functions as an access point in a network connection. Also, the master station device 100 may be a mobile base station of a communication carrier. Further, the master station device 100 may be mounted on an unmanned aerial vehicle or a flying ship. An unmanned aerial vehicle may also be called a UAV (Unmanned Aerial Vehicle), a small unmanned aircraft, or a drone.

[0026] The slave station device 200 is, for example, a mobile phone, a smartphone, a tablet terminal, etc., but is not limited to this example. For example, the slave station device 200 may be a wearable terminal. Also, the slave station device 200 may be a device that can communicate with the master station device 100 and output the progress instruction information described later in a predetermined form. The slave station device 200 can be connected to the Internet via the master station device 100.

[0027] FIG. 4 is a block diagram showing an example of the functional configuration of another example of the guidance support system 1000 according to the first embodiment. As shown in FIG. 4, the guidance support system 1000 includes a master station device 100 and a slave station device 200. The other example shown in FIG. 4 includes the functional configuration of the guidance support system 1000 shown in FIG. 1.

[0028] [Details of the slave station device 200] The slave station device 200 includes a communication unit 210, an intrusion detection unit 220, an output unit 230, and a route information management unit 240. Further, the slave station device 200 includes a storage device 290.

[0029] The communication unit 210 performs various communications with the master station device 100. For example, the communication unit 210 transmits the route information described later to the master station device 100. Also, for example, the communication unit 210 acquires the progress instruction information and the identification information transmitted from the master station device 100.

[0030] The intrusion detection unit 220 detects that the slave unit device 200 has intruded into the communication range of any of the master unit devices 100. For example, the intrusion detection unit 220 receives a signal transmitted by the master unit device 100. At this time, the intrusion detection unit 220 calculates the intensity of the signal. The value of the intensity of the signal received by the intrusion detection unit 220 may also be referred to as the received electric field intensity or the received signal strength. In the present disclosure, the value of the intensity of the signal received by the intrusion detection unit 220 is referred to as the received electric field intensity. For example, when the received electric field intensity is equal to or greater than a predetermined threshold value, the intrusion detection unit 220 detects that the slave unit device 200 has intruded into the communication range of the master unit device 100 that transmitted the received signal. That is, the communication range may be a range in which the master unit device 100 and the slave unit device 200 can communicate at a received electric field intensity equal to or greater than a predetermined threshold value. The intrusion detection unit 220 may notify the master unit device 100 of the intrusion into the communication range, or may notify the master unit device 100 of the calculated received electric field intensity. In this way, when the slave unit device and one master unit device can communicate at a received electric field intensity equal to or greater than a predetermined threshold value, the intrusion detection unit 220 detects that the slave unit device has intruded into the communication range of the one master unit device. The intrusion detection unit 220 is an example of an intrusion detection means. Note that in the present disclosure, the threshold value of the received electric field intensity set to detect that the slave unit device 200 has intruded into the communication range is also referred to as the first threshold value.

[0031] The output unit 230 corresponds to the output unit 1200. The output unit 230 outputs progress instruction information. Specifically, the output unit 230 outputs information indicating a direction on a display device such as a display included in the slave unit device 200. For example, if the progress instruction information includes information indicating a right turn, the output unit 230 displays character information such as "Please make a right turn" on the display device. At this time, the output unit 230 may also display a graphic such as an arrow indicating the progress direction. Note that the example in which the output unit 230 outputs progress instruction information is not limited to this example. For example, the output unit 230 may output the progress instruction information as sound using a speaker included in the slave unit device 200. Also, for example, if the slave unit device 200 is provided with a lamp associated with each progress direction, the output unit 230 may output by changing the lamp that lights up according to the progress instruction information. Further, when the slave unit device 200 is a wearable terminal, the output unit 230 applies a force (referred to as a tensile force) that pulls in the direction to progress, vibrates when facing the direction to progress, or irradiates light in the direction to progress according to the progress instruction information, thereby outputting the progress instruction information. That is, the output unit 230 may output the progress instruction information by generating at least any one of sound according to the direction in which the slave unit device 200 should move, vibration according to the direction in which the slave unit device 200 should move, and tensile force according to the direction in which the slave unit device 200 should move, in the slave unit device 200.

[0032] The routing information management unit 240 manages routing information. The routing information is information regarding the communication range through which the slave unit device 200 passed when it moved. The routing information is stored in the storage device 290. FIG. 5 shows an example of the routing information. In the routing information, the routing number, which is the order of entry, and the identification information of the master unit device 100 having the communication range are associated with respect to the communication range that the slave unit device 200 invaded in the past. In the example of FIG. 5, it is shown that the slave unit device 200 first invaded the communication range of the master unit device 100 whose identification information is "D", and second invaded the communication range of the master unit device 100 whose identification information is "A". Note that the configuration of the routing information is not limited to this example, and any configuration may be used as long as the order of the communication ranges through which the slave unit device 200 passed when it moved can be understood.

[0033] When the slave unit device 200 newly invades a communication range, the routing information management unit 240 updates the routing information stored in the storage device 290. For example, assume that the routing information shown in FIG. 5 is stored in the storage device 290. And assume that the slave unit device 200 newly invades the communication range of the master unit device 100 whose identification information is "C". In this case, the routing information management unit 240 adds information indicating that it invaded the communication range of the master unit device 100 whose identification information is "C" third to the routing information in FIG. 5. Thus, in the example of FIG. 5, the record with the largest routing number in the routing information becomes the latest record. The routing information management unit 240 can also specify the identification information of the master unit device 100 having the communication range that the slave unit device 200 most recently invaded, that is, the latest record of the routing information. Hereinafter, the identification information of the master unit device 100 having the communication range that the slave unit device 200 most recently invaded is also referred to as the latest identification information.

[0034] The routing information management unit 240 transmits the routing information including the latest identification information to the master unit device 100 via the communication unit 210.

[0035] [Details of the master unit device 100] The master unit device 100 includes a communication unit 110 and a specifying unit 120. Further, the master unit device 100 includes a storage device 190.

[0036] The communication unit 110 communicates with the slave unit device 200. For example, the communication unit 110 transmits progress instruction information and its own device identification information to the slave unit device 200. Also, for example, the communication unit 110 acquires the route information transmitted from the slave unit device 200.

[0037] The specifying unit 120 corresponds to the specifying unit 1100. The specifying unit 120 specifies the progress instruction information. Specifically, the specifying unit 120 acquires the identification information (i.e., the latest identification information) of the master unit device 100 that has a communication range that the slave unit device 200 has entered before entering the communication range of its own device. The specifying unit 120 acquires the latest identification information from the slave unit device 200 via, for example, the communication unit 110.

[0038] Then, the specifying unit 120 specifies progress instruction information corresponding to the latest identification information based on the instruction pattern information. Here, the instruction pattern information is information in which the route of the communication range through which the slave unit device 200 has passed and the progress instruction information are associated before the slave unit device 200 enters the communication range of its own device. The instruction pattern information is stored in the storage device 190. FIG. 6 is a diagram showing an example of the instruction pattern information. In the record on the first line of FIG. 6, it is shown that when the communication range of the master unit device 100 with identification information "A" is followed by entry into the communication range of the master unit device 100 with identification information "B", the progress instruction information indicating "turn right" is associated. Therefore, for example, in the master unit device 100, when its own device identification information is "B" and the identification information "A" is acquired as the latest identification information, the specifying unit 120 specifies the progress instruction information indicating "turn right".

[0039] Here, with reference to FIGS. 6 and 7, the relationship between the route of the slave unit device 200 and the progress instruction information will be described. FIG. 7 is a diagram showing the location where the master unit device 100 is installed on the map. In FIG. 7, the alphabets A to G described above each of the master unit devices 100 indicate the respective identification information of the master unit devices 100. The point P indicates a point within the communication range of the master unit device 100 with the identification information "B", the point Q indicates a point within the communication range of the master unit device 100 with the identification information "A", the point R indicates a point within the communication range of the master unit device 100 with the identification information "E", and the point S indicates a point within the communication range of the master unit device 100 with the identification information "C". In this example, it is assumed that the guidance support system 1000 guides the user who has the slave unit device 200 to the evacuation shelter which is the destination. Assume that the user is present at the point P. In this case, the guidance support system 1000 guides the user from the point P to the point R in order to guide the user to the evacuation shelter which is the destination.

[0040] Here, when the latest identification information is "A", the user is considered to have moved from point Q to point P. In this case, since it is inferred that the user is facing in the direction of point S, the user can be guided to point R by giving the user an instruction to turn right. Therefore, in the first row record of the instruction pattern information in FIG. 6, when entering the communication range of the parent station device 100 with identification information "B" via the communication range of the parent station device 100 with identification information "A", the progress instruction information indicating "turn right" is associated. Similarly, when the latest identification information is "C", the user is considered to have moved from point S to point P. Therefore, in order to give the user an instruction to turn left, in the instruction pattern information, when entering the communication range of the parent station device 100 with identification information "B" via the communication range of the parent station device 100 with identification information "C", the progress instruction information indicating "turn left" is associated. Also, when the latest identification information is "E", the user is considered to have moved from point R to point P. Therefore, in order to give the user an instruction to proceed in the opposite direction, in the instruction pattern information, when entering the communication range of the parent station device 100 with identification information "B" via the communication range of the parent station device 100 with identification information "E", the progress instruction information indicating "opposite" is associated.

[0041] In addition, for the case where the user is present in the communication range of the parent station device near the destination, information indicating that the destination is near may be associated as the progress instruction information in the instruction pattern information.

[0042] Also, the storage device 190 included in each of the master station devices 100 may store instruction pattern information that is different for each master station device 100. For example, each of the master station devices 100 may have instruction pattern information that includes only the progress instruction information from its own communication range. In other words, since not all of the master station devices 100 need to have the position information of the destination and the progress instruction information to the destination, the pressure on the capacity of the storage device 190 can be suppressed. Note that the storage device 190 included in each of the master station devices 100 may store instruction pattern information that covers the patterns of combinations of identification information. Note that the instruction pattern information is, for example, created in advance by an external device (not shown) that can communicate with each of the master station devices 100. The instruction pattern information is created, for example, based on the position information of the destination, the position information of the master station device 100, and the map information including roads. The master station device 100 may store the instruction pattern information in the storage device 190 by receiving the instruction pattern information in advance from the external device via a network.

[0043] Furthermore, as described above, the specifying unit 120 uses the identification information of the master station device 100 when specifying the progress instruction information. That is, the master station device 100 does not necessarily have to hold the position information of the master station device 100, the map information, etc. Therefore, the capacity of the storage device 190 of the master station device 100 can be further suppressed.

[0044] Then, the specifying unit 120 transmits the specified progress instruction information and its own device's identification information to the slave station device 200 via the communication unit 110. Note that when the storage device 190 stores information indicating the distance from its own device's communication range to the destination, the specifying unit 120 may transmit the information indicating the distance to the slave station device 200.

[0045] [Operation of the Navigation Support System 1000] Next, an example of the operation of the navigation support system 1000 will be described with reference to FIG. 8. Note that the master station device 100 described in this operation example is the master station device having the communication range when the slave station device 200 enters the communication range.

[0046] Figure 8 is a sequence diagram for explaining an example of the operation of another example of the induction support system 1000. The intrusion detection unit 220 detects that the slave unit device 200 has intruded into the communication range of any of the master unit devices 100 ("Yes" in S101). Then, the route information management unit 240 reads the route information and transmits the read route information to the master unit device 100 via the communication unit 210 (S102). At this time, the route information management unit 240 may transmit the route information to the master unit device 100, or may extract the latest identification information from the route information and transmit the extracted latest identification information to the master unit device 100. Note that when not intruding into the communication range of the master unit device 100 ("No" in S101), the slave unit device 200 does not proceed with the process.

[0047] The specifying unit 120 of the master unit device 100 acquires the latest identification information via the communication unit 110 (S103). The specifying unit 120 specifies the progress instruction information according to the latest identification information (S104). For example, the specifying unit 120 reads the instruction pattern information from the storage device 190 and specifies the progress instruction information corresponding to the case where the slave unit device 200 moves from the communication range of the master unit of the latest identification information to its own communication range. Then, the communication unit 110 transmits the specified progress instruction information and its own device identification information to the slave unit device 200 (S105).

[0048] When the output unit 230 of the slave unit device 200 receives the progress instruction information via the communication unit 210, it outputs the progress instruction information by a predetermined method (S106). For example, when the progress instruction information includes information indicating "turn right", the output unit 230 displays character information "Please turn right" on the display device of the slave unit device 200. When the route information management unit 240 receives the identification information of the master unit via the communication unit 210, it updates the route information using the received identification information (S107). For example, the route information management unit 240 updates the route information so that the received identification information is the latest identification information. Note that the processes of S106 and S107 may be performed in the reverse order or simultaneously.

[0049] In the process of S102, when the routing information does not include the identification information of any parent device 100, the routing information management unit 240 notifies the parent device 100 via the communication unit 210 that the routing information does not include the identification information. In this case, when receiving the notification, instead of performing the processes of S103 to S105, the communication unit 110 of the parent device 100 transmits the identification information of its own device to the slave device 200. Then, the routing information management unit 240 of the slave device 200 performs the process of S107.

[0050] As described above, when the slave device enters the communication range of one parent device, the guidance support system 1000 according to the first embodiment specifies the progress instruction information including the information on the direction in which the slave device should move according to the combination of the identification information of one parent device and the identification information of another parent device having the communication range that the slave device existed in before entering the communication range. Then, the guidance support system 1000 outputs the progress instruction information at the slave device 200. With this configuration, the guidance support system 1000 can provide the user with the direction in which the user should move in order to reach the destination according to the route that the user of the slave device 200 has traveled. Furthermore, since the guidance support system 1000 can provide the information on the direction in which the user should move, even when the user is not used to reading a map, the user can be quickly guided. That is, the guidance support system 1000 according to the first embodiment can appropriately guide the user.

[0051] Also, when the slave device 200 enters the communication range that the parent device 100 of the first embodiment has, the parent device 100 specifies the progress instruction information including the information on the direction in which the slave device should move according to the combination of the identification information of its own device and the identification information of another parent device having the communication range that the slave device 200 existed in before entering the communication range. Thereby, the parent device 100 can provide the user of the slave device 200 with the information on the direction in which the user should move by transmitting the progress instruction information to the slave device 200. That is, the parent device 100 can support the guidance of the user.

[0052] Then, the slave unit device 200 outputs progress instruction information including information on the direction to move, which is specified according to a combination of the identification information of one master unit device having the communication range in which the own device has intruded and the identification information of another master unit device having the communication range that existed before the own device intruded into the communication range. Thereby, information on the direction to move can be provided to the user of the slave unit device 200. That is, the slave unit device 200 can assist in guiding the user.

[0053] Also, for example, at the time of a disaster, a communication line network that is communicably connected to the master unit device 100 may be cut off, such as a communication line network (sometimes called a core network, backbone network, or backbone communication network, etc.) that connects between communication carriers' bases and between operators. That is, there may be a case where the slave unit device 200 cannot be connected to the Internet via the master unit device 100. Even in such a case, the processing of the guidance support system 1000 of the first embodiment can be executed as long as communication between the master unit device 100 and the slave unit device 200 is possible. That is, even when the slave unit device 200 cannot be connected to the Internet, it is possible to guide the user to the destination.

[0054] [Modification Example 1] The intrusion detection unit 220 may be provided in the master unit device 100. In this case, the intrusion detection unit 220 receives the signal emitted by the slave unit device 200 and calculates the received electric field strength. Then, when the received electric field strength is equal to or greater than a predetermined threshold value, the intrusion detection unit 220 detects that the slave unit device 200 has intruded into the communication range of the master unit device 100 (the own device). And when the slave unit device 200 intrudes into the communication range, the intrusion detection unit 220 sends a notification indicating that it has intruded into the communication range. The route information management unit 240 of the slave unit device 200 acquires the notification via the communication unit 210 and transmits the route information to the master unit device 100 according to the notification.

[0055] [Modification Example 2] In the first embodiment, the master unit device 100 specifies the progress instruction information, but the slave unit device 200 may also specify the progress instruction information.

[0056] FIG. 9 is a block diagram showing an example of the functional configuration of the guidance support system 1000 according to the second modification. As shown in FIG. 9, in the second modification, the slave unit device 200 includes a communication unit 210, an output unit 230, a route information management unit 240, an identification unit 120, and a storage device 290. Further, in the second modification, the master unit device 100 includes a communication unit 110, an intrusion detection unit 220, and a storage device 190. Note that, in this modification, the intrusion detection unit 220 is provided in the master unit device 100, but as described above, the intrusion detection unit 220 may be provided in the slave unit device 200.

[0057] FIG. 10 is a diagram showing an example of the instruction pattern information according to the second modification. In the second modification, the instruction pattern information is stored in the storage device 290 of the slave unit device 200. The slave unit device 200 may acquire the instruction pattern information, for example, from a device (not shown) in advance via a network, or may acquire it from any of the master unit devices 100.

[0058] FIG. 11 is a sequence diagram for explaining an example of the operation of the guidance support system 1000 according to the second modification. The intrusion detection unit 220 of the master unit device 100 detects that the slave unit device 200 has intruded into the communication range of the master unit device 100 ("Yes" in S201). Then, the communication unit 110 transmits the identification information of its own device to the slave unit device 200 (S202). Note that when the slave unit device 200 has not intruded into the communication range of the master unit device 100 ("No" in S201), the master unit device 100 does not proceed with the process.

[0059] The identification unit 120 of the slave unit device 200 acquires the latest identification information from the route information and acquires the identification information received via the communication unit 110 (S203). The identification unit 120 specifies the progress instruction information according to the combination of the acquired identification information (S204). Then, the output unit 230 outputs the progress instruction information (S205). The route information management unit 240 updates the route information using the received identification information (S206).

[0060] In addition, in the process of S203, if the latest identification information is not included in the route information, the slave station device 200 performs the process of S206.

[0061] As described above, in the second modification, the slave station device 200 specifies the progress instruction information including the information on the direction in which the device should move according to the combination of the identification information of one master station device having the communication range in which the device has intruded and the identification information of another master station device having the communication range that existed before the device intruded into the communication range. Then, the slave station device 200 outputs the progress instruction information.

[0062] With the above configuration, the guidance support system 1000 according to the second modification also exhibits the same effects as the guidance support system 1000 described in the first embodiment.

[0063] [Second Modification] The functions of the slave station device 200 described above are executed by, for example, an application developed on the slave station device 200. The activation of the application is performed, for example, by a user input, but is not limited to this example.

[0064] For example, in the slave station device 200, when disaster prevention-related information is received, the application may be executed. The disaster prevention-related information may be, for example, various warnings such as an emergency earthquake early warning and a tsunami warning distributed by a public office, or evacuation information indicating a call for evacuation announced by a local government. Further, the disaster prevention-related information may be a notification including various warnings or evacuation information and transmitted as an emergency report from a communication carrier.

[0065] When the slave unit device 200 includes an intrusion detection unit 220, for example, when disaster prevention-related information is received in the slave unit device 200, an application is activated and the intrusion detection unit 220 starts processing. Also, when the master unit device 100 includes the intrusion detection unit 220, when the slave unit device 200 receives disaster prevention-related information and the application is activated, the slave unit device 200 may be able to receive a notification indicating that it has entered the communication range, or the slave unit device 200 may be configured to emit a signal necessary when the intrusion detection unit 220 performs detection.

[0066] <Second Embodiment> Next, the guidance support system according to the second embodiment will be described.

[0067] FIG. 12 is a block diagram including the functional configuration of the guidance support system 1001 according to the second embodiment. As shown in FIG. 12, the guidance support system 1001 includes a master unit device 101 and a slave unit device 201. Here, the master unit device 101 is a name when the master unit devices 101-1, 101-2, ···, 101-n are not distinguished, similar to the master unit device 100 of the first embodiment. Note that in the second embodiment, some descriptions of the content overlapping with that described in the first embodiment will be omitted.

[0068] [Details of the Master Unit Device 101] The master unit device 101 includes a communication unit 110, a specifying unit 120, a position information estimating unit 130, a route calculating unit 140, and a storage device 190.

[0069] The location information estimation unit 130 estimates the location information of the slave station device 201. For example, assume that the slave station device 201 has entered the communication range of the master station device 101. The location information estimation unit 130 estimates, for example, the location corresponding to the communication range of the master station device 101 as the location information indicating the location where the slave station device 201 exists. At this time, information in which the communication range and the location information are associated is stored in the storage device 190. In the example of FIG. 7, for example, the communication range of the master station device whose identification information is "B" and the point P are associated. For example, when the slave station device 201 enters the communication range of the master station device 101 whose identification information is "B", the location information estimation unit 130 estimates that the slave station device 201 exists at the point P. The location information is, for example, latitude and longitude, but is not limited to this example. The location information may be information indicating an address, information indicating an intersection, or information indicating a building (for example, a public facility, a supermarket, and a convenience store, etc.). In this way, the location information estimation unit 130 estimates the location information of the slave station device 200 based on the communication range of the master station device 100. The location information estimation unit 130 is an example of location information estimation means.

[0070] Furthermore, the position information estimation unit 130 may estimate the position information of the slave station device 201 according to the received electric field strength. For example, in the communication between the slave station device 201 and the master station device 101, it is estimated that the closer the slave station device 201 is to the master station device 101, the greater the received electric field strength. Therefore, the position information corresponding to the case where the received electric field strength is equal to or greater than the second threshold value and the position information corresponding to the case where the received electric field strength is less than the second threshold value are determined in advance. The second threshold value is a value equal to or greater than the first threshold value. Then, the position information estimation unit 130 acquires information indicating the received electric field strength from the intrusion detection unit 220, and estimates different position information according to whether the received electric field strength exceeds the second threshold value. At this time, the position information estimation unit 130 may estimate the position information so as to indicate different locations according to whether the received electric field strength exceeds the second threshold value, or may estimate position information with different ranges. For example, when the received electric field strength is less than the second threshold value, the position information estimation unit 130 may estimate, as the position information, a range within 50 meters from the master station device 101, and when the received electric field strength is equal to or greater than the second threshold value, may estimate, as the position information, a range within 20 meters from the master station device 101. Note that a plurality of second threshold values may be determined.

[0071] The route calculation unit 140 calculates the route along which the slave station device 201 has moved based on the route information. In the storage device 190, the identification information of each master station device 101 and the position information corresponding to the communication range of each master station device 101 are stored in association with each other in advance. The route calculation unit 140 acquires the route information from the slave station device 201 via the communication unit 110. The route calculation unit 140 calculates the route until the slave station device 201 moves to the position information estimated by the position information estimation unit 130 based on the route information. For example, the route calculation unit 140 arranges the position information corresponding to the identification information included in the route information in the order of the route numbers, and interpolates between the respective pieces of position information using the map information to generate a route. The map information is stored in the storage device 190, for example. The route calculation unit 140 transmits the information indicating the calculated route to the slave station device 201 via the communication unit 110. The route calculation unit 140 may transmit, for example, the information showing the calculated route and the position information estimated by the position information estimation unit 130 on the map as the information indicating the route to the slave station device 201 via the communication unit 110. In this way, the route calculation unit 140 calculates the route along which the slave station device 201 has moved based on the information in which the position information is associated in advance for each communication range and the route information. Note that, in addition to the calculated route and the estimated position information, the route calculation unit 140 may further transmit the information showing the destination location on the map as the information indicating the route. In this case, for example, the position information of the destination is stored in the storage device 190 in advance.

[0072] [Details of Slave Station Device 201] The slave station device 201 includes a communication unit 210, an intrusion detection unit 220, an output unit 231, a route information management unit 240, and a storage device 290.

[0073] The output unit 231 outputs information indicating the path transmitted from the master station device 101 in addition to the progress instruction information. FIG. 13 is a diagram showing an example of the information output in the slave station device 201. In the example of FIG. 13, on the map, the path along which the slave station device 201 has moved is indicated by an arrow, and the current location is indicated by a star mark. Also, as the progress instruction information, character information "Please turn right" is shown. Further, the location of the evacuation shelter as the destination and the distance to the evacuation shelter are also shown. The output unit 231 displays information as shown in FIG. 13 on, for example, a display device provided in the slave station device 201.

[0074] [Operation of the Guidance Support System 1001] Next, an example of the operation of the guidance support system 1001 will be described with reference to FIG. 14.

[0075] FIG. 14 is a sequence diagram for explaining an example of the operation of the guidance support system 1001. The process of S301 is the same as that of S101 in FIG. 8. Next, the route information management unit 240 reads out the route information and transmits the read route information to the master station device 101 via the communication unit 210 (S302).

[0076] The processes of S303 and S304 in the master station device 101 are the same as the processes of S103 and S104 in FIG. 8. Next, the position information estimation unit 130 estimates the position information of the slave station device 201 according to the communication range of the master station device 101 (S305). Then, the route calculation unit 140 calculates the route along which the slave station device 201 has moved until it enters the communication range of its own device based on the route information (S306). The communication unit 110 transmits the progress instruction information, its own device identification information, and the information indicating the route to the slave station device 201 (S307). At this time, as the information indicating the route, the communication unit 110 transmits, for example, the information showing the calculated route and the position information estimated by the position information estimation unit 130 on the map. Note that the processes of S305 and S306 may be performed before the process of S303 or may be performed before the process of S304.

[0077] The output unit 231 of the slave station device 201 outputs the information received from the master station device 101 (S308). For example, the output unit 231 outputs information as shown in FIG. 13. The process of S309 is the same as the process of S107 in FIG. 8.

[0078] As described above, when the slave station device enters the communication range of one master station device, the guidance support system 1001 of the second embodiment specifies the progress instruction information including the information on the direction in which the slave station device should move according to the combination of the identification information of one master station device and the identification information of another master station device having the communication range that existed before the slave station device entered the communication range. Then, the guidance support system 1001 outputs the progress instruction information in the slave station device 200. With this configuration, the guidance support system 1001 has the same effect as the guidance support system 1000 of the first embodiment. That is, the guidance support system 1001 of the second embodiment can appropriately guide the user.

[0079] In addition, the guidance support system 1001 of the second embodiment estimates the position information of the slave station device based on the communication range of one master station device, which is the communication range in which the slave station device has entered, and outputs the estimated position information of the slave station device. For example, due to a disaster or the like, it may be impossible to obtain position information using GNSS (Global Navigation Satellite System) such as GPS (Global Positioning System) or the Internet in the slave station device 201. Even in such a case, the slave station device 201 can output the position information. That is, the guidance support system 1001 can provide the position information to the user who holds the slave station device even when it is impossible to obtain the position information using GNSS or the Internet.

[0080] In addition, the guidance support system 1001 of the second embodiment calculates the route along which the slave unit device has moved based on information in which location information is associated in advance for each communication range and route information. As a result, even when GNSS or the Internet cannot be used, the guidance support system 1001 can provide the user who holds the slave unit device with the route that has been traveled so far.

[0081] [Modification Example 4] In the above example, the communication unit 110 of the master unit device 101 transmits, as information indicating the route, the information showing the route calculated by the route calculation unit 140 and the location information estimated by the location information estimation unit 130 on the map to the slave unit device 201. Not limited to this example, for example, the communication unit 110 may transmit only the information indicating the calculated route and the estimated location information to the slave unit device 201. In this case, for example, the output unit 231 of the slave unit device 201 acquires the map information stored in advance in the storage device 290. Then, the route and location information received from the master unit device 101 may be superimposed on the map information, and the superimposed information may be output.

[0082] <Third Embodiment> Next, the guidance support system of the third embodiment will be described. In the third embodiment, the processing of the guidance support system when there are multiple shelters will be described.

[0083] FIG. 15 is a block diagram including the functional configuration of the guidance support system 1002 of the third embodiment. As shown in FIG. 15, the guidance support system 1002 includes a master unit device 102 and a slave unit device 202. Here, the master unit device 102 is a name when the master unit devices 102-1, 102-2, ···, 102-n are not distinguished, similar to the master unit device 100 of the first embodiment. In the third embodiment, some descriptions of the content overlapping with that described in the first and second embodiments will be omitted.

[0084] [Details of Slave Unit Device 202] The slave station device 202 includes a communication unit 210, an intrusion detection unit 220, an output unit 230, a route information management unit 240, an attribute information acquisition unit 250, and a storage device 290.

[0085] The attribute information acquisition unit 250 acquires the attribute information of the user who owns the slave station device 202. The attribute information is information in which the slave station identification information, which is information for identifying the slave station, is associated with the attributes of the user. The attributes are, for example, the age, gender, address, presence or absence of a physical disability, and whether the user has an infant child, but are not limited to this example. FIG. 16 is a diagram showing an example of the attribute information. In the example of FIG. 16, the user with the slave station identification number "001" has an "age" of "20 years old", a "gender" of "male", and an "address" of "City Y, Prefecture X". Also, in the example of FIG. 16, it is shown that the user has a "physical disability" and no "infant" child. The attribute information is generated in advance by the user's input. The attribute information is stored in the storage device 290. The attribute information is transmitted to the master station device 102 by the communication unit 210.

[0086] [Details of the master station device 102] The master station device 102 includes a communication unit 110, a specifying unit 121, a destination selection unit 150, and a storage device 190.

[0087] The destination selection unit 150 selects a destination. Specifically, the destination selection unit 150 selects a destination corresponding to the attribute information from the destination information. The destination information is information in which, for each destination, information indicating the location information of the destination, the capacity of the destination, and whether the destination is a barrier-free facility, etc. is associated. Note that the information included in the destination information is not limited to this example. For example, when the attribute information includes information indicating that the user has a physical disability, the destination selection unit 150 selects a destination that is a barrier-free facility among a plurality of destinations. Also, for example, when the attribute information includes information indicating that the user has an infant or child, the destination selection unit 150 selects a destination close to the position of its own device. In this way, the destination selection unit 150 selects a destination according to the attributes of the user who holds the slave device 202. The destination selection unit 150 is an example of a destination selection means.

[0088] The specifying unit 121 specifies progress instruction information according to the selected destination. Specifically, the specifying unit 121 reads out, for example, the instruction pattern information corresponding to the destination selected by the destination selection unit 150. Then, the specifying unit 121 specifies progress instruction information according to the latest identification information acquired from the slave device 201 based on the read instruction pattern information. FIG. 17 is a diagram showing an example of a plurality of instruction pattern information. As shown in FIG. 17, in the third embodiment, the instruction pattern information corresponding to each of the destinations is stored in the storage device 190. For example, when the destination selection unit 150 selects "destination 1", the specifying unit 121 specifies progress instruction information from the instruction pattern information corresponding to "destination 1".

[0089] [Operation of the Guidance Support System 1002] Next, an example of the operation of the guidance support system 1002 will be described with reference to FIG. 18.

[0090] FIG. 18 is a sequence diagram for explaining an example of the operation of the guidance support system 1002. The process of S401 is the same as that of S101 in FIG. 8. Next, the communication unit 210 transmits the route information and the attribute information to the master station device 102 (S402). Specifically, the route information management unit 240 acquires the route information, and the attribute information acquisition unit 250 acquires the attribute information. Then, the communication unit 210 transmits the acquired route information and attribute information.

[0091] The process of S403 is the same as the process of S103 in FIG. 8. Next, the destination selection unit 150 selects a destination based on the attribute information (S404). The specifying unit 121 specifies the progress instruction information corresponding to the latest identification information from the instruction pattern information corresponding to the destination (S405). The communication unit 110 transmits the progress instruction information and the identification information of its own device (S406). The processes of S407 and S408 are the same as the processes of S106 and S107 in FIG. 8.

[0092] As described above, the guidance support system 1002 of the third embodiment selects a destination according to the attribute of the user who holds the slave station device, and specifies the progress instruction information corresponding to the selected destination. Thereby, the guidance support system 1002 can guide the user to a destination according to the user's attribute. That is, the guidance support system 1002 of the third embodiment can appropriately guide the user.

[0093] [Modification Example 5] The slave station device 202 may have a destination selection unit 150. In this case, the destination information is stored in the storage device 290 in advance. For example, in the operation example of FIG. 18, the destination selection unit 150 included in the slave station device 202 selects a destination based on the attribute information after the "Yes" process of S401. Then, instead of the process of S402, the communication unit 210 transmits the route information and the destination identification information for identifying the selected destination to the master station device 102. After the process of S403, the master station device 102 performs the processes after S405.

[0094] Also, similar to Modification Example 2, when the slave station device 202 specifies the progress instruction information (that is, when the slave station device 202 has the specifying unit 121), in the operation example of FIG. 11, the destination selection unit 150 included in the slave station device 202 selects a destination based on the attribute information after the process of S203. Then, instead of the process of S204, the specifying unit 121 included in the slave station device 202 specifies the progress instruction information corresponding to the latest identification information from the instruction pattern information corresponding to the destination. In this case, the instruction pattern information corresponding to each destination is stored in the storage device 290. Then, the slave station device 202 performs the processes after S205.

[0095] [Modification Example 6] The communication unit 110 of the master station device 102 may transmit the destination identification information of the selected destination to the slave station device 202. In this case, the destination selection unit 150 specifies the destination identification information of the selected destination. For example, in the process of S406 in the operation example of FIG. 18, the communication unit 110 transmits the destination identification information of the selected destination to the slave station device 202.

[0096] When the slave station device 202 enters the communication range of another master station device 102, the communication unit 210 of the slave station device 202 may transmit the destination identification information together with the route information to the master station device 102. Then, the specifying unit 121 of the master station device 102 reads out the instruction pattern information corresponding to the destination from the transmitted destination identification information and specifies the progress instruction information. Thereby, once the destination corresponding to the user of the slave station device 202 is selected, the master station device 102 can specify the progress instruction information without performing the process of selecting the destination again.

[0097] [Modification Example 7] In the third embodiment, the destination selection unit 150 selects a destination based on the attributes of the user who holds the slave station device 202, but the destination may be selected using other information. For example, the destination selection unit 150 may select a destination based on the slave station identification information that identifies the slave station device 202. Specifically, the destination selection unit 150 selects a destination corresponding to the slave station identification information. In this case, the destination information includes correspondence information indicating the corresponding slave station identification information for each destination.

[0098] For example, when the slave station identification information is represented by numbers, information such as odd or even numbers is set as the correspondence information. Then, the destination selection unit 150 may perform processing such as selecting destination 1 when the slave station identification information is odd and selecting destination 2 when the slave station identification information is even. Also, when the remainder obtained by dividing the slave station identification information by a predetermined number is set as the correspondence information, the destination selection unit 150 may select a destination according to the remainder. Also, when a predetermined number is set as the correspondence information, the destination may be selected according to the last digit of the slave station identification information.

[0099] Also, when the slave station identification information includes characters such as alphabets, the destination selection unit 150 may select a destination corresponding to the last character of the slave station identification information, or may convert the slave station identification information into a numerical value according to a predetermined rule and select a destination corresponding to the numerical value.

[0100] In this way, by allocating in advance the destinations for guiding the user according to the slave station device 202, the number of people can be adjusted so that the number of people does not concentrate on some destinations. For example, by performing such an adjustment of the number of people, the guidance support system 1002 of Modification 7 can adjust the population density within the destination, and thus can contribute to infectious disease countermeasures.

[0101] [Modification 8] The destination selection unit 150 may select a destination according to the distance from the communication range of the parent station device 102 to the destination. For example, assume that information indicating the distance from the communication range of the parent station device 102 including the storage device 190 to each destination is stored in the storage device 190. The destination selection unit 150 selects the destination with the shortest distance, and the specifying unit 121 specifies the progress instruction information from the instruction pattern information corresponding to the selected destination.

[0102] For example, assume that a user who holds the slave station device 202 has advanced in the wrong direction of travel. In this case, the user may be moving away from the original destination. Therefore, if the user is guided to the original destination, there is a possibility that the time required to guide the user to the destination will increase. In contrast, the destination selection unit 150 of Modification 8 selects the destination with the shortest distance to the destination. That is, the guidance support system 1002 of Modification 8 can guide the user to another destination closer than the original destination when the user is moving away from the original destination and there is another destination closer than the original destination within the communication range where the user is present. Thereby, for example, when guiding a user to an evacuation shelter as the destination during a disaster, the user can be quickly guided to any evacuation shelter.

[0103] [Modification 9] In the guidance support system described in the first, second, and third embodiments, it is also possible to use the fifth-generation mobile communication system (5th Generation Mobile Communication System: 5G). Here, the base station used in the fifth-generation mobile communication system is referred to as a 5G base station.

[0104] FIG. 19 is a block diagram including the functional configuration of the guidance support system 1003 of Modification 9. As shown in FIG. 19, the guidance support system 1003 includes a parent station device 103, a slave station device 203, and a 5G base station 300. Here, the parent station device 103 is a name when not distinguishing the parent station devices 103-1, 103-2, ···, 103-n, similar to the parent station device 100 of the first embodiment. There are a plurality of 5G base stations, and each of the 5G base stations 300 is communicably connected to each of the parent station devices 103. At least, there are 5G base stations 300 in a number equal to or greater than that of the parent station device 103. Also, the slave station device 203 is communicable with the 5G base station 300. The 5G base station 300 is connected to a communication line network called a backbone network. The slave station device 203 is connected to the Internet via the 5G base station 300.

[0105] The communication unit 210 of the slave station device 203 transmits and receives various information to and from the 5G base station 300. Also, the communication unit 110 of the parent station device 103 transmits and receives various information to and from the 5G base station 300. That is, the slave station device 203 and the parent station device 103 transmit and receive various information via the 5G base station.

[0106] The intrusion detection unit 222 of the slave station device 203 detects intrusion into the communication range of the 5G base station. That is, the guidance support system 1003 is a system that outputs progress instruction information to the slave station device 203 when the slave station device 203 intrudes into the communication range of the 5G base station 300. At this time, the identification information used to specify the progress instruction information may be the identification information of the parent station device 103 or the identification information for identifying the 5G base station.

[0107] The 5G base station 300 includes a communication unit 310 and a mode switching unit 320. The communication unit 310 transmits various information received from the parent station device 103 to the child station device 203. Also, the communication unit 310 transmits various information received from the child station device 203 to the parent station device 103. The mode switching unit 320 switches the mode set in the 5G base station 300. In the fifth-generation mobile communication system, if the backbone network connected to the 5G base station 300 is cut off, the 5G base station itself may stop. Therefore, the mode switching unit 320 switches the mode set in the 5G base station 300 so that at least communication with the terminal can be established even when the backbone network is cut off. For example, the mode switching unit 320 may switch the mode when it detects the cut-off of the backbone network. Thereby, communication between the 5G base station 300 and the child station device 203 is enabled even when the backbone network is cut off.

[0108] In this way, by using the fifth-generation mobile communication system, it becomes possible to connect more child station devices 203 to the 5G base station 300. Therefore, in the guidance support system 1003, it is possible to present travel guidance information to more child station devices 203.

[0109] Note that in this modification example, the 5G base station 300 may have the functions of the parent station device 103. That is, the 5G base station 300 may be the parent station device.

[0110] [Modification Example 10] In the first, second, and third embodiments, each of the parent station devices may be communicably connected to the parent station center facility. FIG. 20 is a diagram schematically showing an example of the configuration of the guidance support system of Modification Example 10. The parent station center facility includes an update control unit. The update control unit updates and manages the information stored in the parent station device by transmitting various information to the parent station device. The parent station device receives various information from the parent station center facility at any time, for example. Then, the parent station device updates information such as instruction pattern information, destination information, and map information based on the received information.

[0111] For example, assume that a non-passable road has occurred or is predicted to occur due to, for example, a river flood, a house collapse, a landslide, etc. In this case, the update control unit of the parent station center facility creates instruction pattern information in the communication range of each parent station device considering the non-passable road. Specifically, the update control unit creates instruction pattern information including travel instruction information that bypasses the non-passable road based on, for example, map information including information on the non-passable road, the position information of the parent station device, and the position information of the destination. The parent station device receives the instruction pattern information from the parent station center facility and updates the instruction pattern information. Thereby, the guidance support system of the present disclosure can guide the user to bypass the non-passable road even when there is a non-passable road. Note that the process of updating information such as the above-described instruction pattern information, destination information, and map information may be performed by, for example, an update unit provided in the parent station device.

Also, the program 18 may be recorded on a storage medium 20 and read using the drive device 17, or may be transmitted from an external device (not shown) to the computer device 10 via a network (not shown).

[0115] The input / output interface 15 exchanges data with peripheral devices (such as a keyboard, a mouse, and a display device) 19. The input / output interface 15 functions as a means for acquiring or outputting data. The bus 16 connects each component.

[0116] Note that there are various modifications to the method of realizing the guidance support system. For example, the guidance support system can be realized as a dedicated device. Also, the guidance support system can be realized based on a combination of a plurality of devices.
