[0009] Hereinafter, an assistance request system, a location information management device, and an assistance request method according to embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0010] Embodiment 1 FIG. 1 is a first diagram illustrating a configuration example of an assistance request system 10 according to the first embodiment. The assistance request system 10 includes a control command device 20, a beacon device 30, guidance display devices 40a and 40b, and a location information management device 50. In the assistance request system 10, the control command device 20 and the beacon device 30 are installed on a train 70. The guidance display devices 40a and 40b are used by users aboard the train 70 and can be used inside and outside the train 70 in conjunction with the user's actions. The guidance display devices 40a and 40b are mobile terminals such as smartphones on which an application that performs the operations described below is installed, but they may also be dedicated terminals. In the following description, when there is no need to distinguish between the guidance display devices 40a and 40b, they will be referred to as the guidance display device 40. The location information management device 50 is a server or the like installed in a ground system (not shown) that manages the operation of the train 70.

[0011] The control command device 20 transmits to the beacon device 30 the train formation information of the train 70 and location information including car information on the train 70. The formation information is identification information such as a train formation number for identifying each of the multiple trains 70. The car information is information indicating which car, from car 1 to car 10, the user is riding in, and the location of the car on the train 70, if the train 70 has 10 cars. The control command device 20 periodically transmits the location information to the beacon device 30 at a specified interval. The control command device 20 can also transmit to the beacon device 30 an emergency guidance command indicating the occurrence of an emergency situation that requires users riding on the train 70 to take evacuation action. An emergency situation that requires users riding on the train 70 to take evacuation action is assumed to be, for example, the occurrence of a disaster such as a fire or an earthquake, but may also include situations such as a suspicious person causing a disturbance on the train 70 or the discovery of a suspicious object on the train 70. The emergency guidance command may simply state that an emergency has occurred that requires users on train 70 to take evacuation action, but since the evacuation action content differs depending on the type of emergency, such as fire or earthquake, as mentioned above, it is better to vary the content of the guidance depending on the type of emergency so that the type, such as fire or earthquake, can be distinguished.

[0012] The control command device 20 transmits an emergency guidance command to the beacon device 30 when a crew member of the train 70 who has detected the occurrence of an emergency operates a button installed in the driver's cab or the like. Note that the control command device 20 may automatically determine the occurrence of an emergency and transmit an emergency guidance command to the beacon device 30 depending on the type of emergency. For example, when the type of emergency is an earthquake, if it is determined that an emergency guidance command is to be transmitted to the beacon device 30 when shaking of a specified seismic intensity or greater is detected, the control command device 20 can quickly transmit an emergency guidance command to the beacon device 30 by detecting shaking of the specified seismic intensity or greater without receiving operation from the crew member of the train 70.

[0013] The beacon device 30 distributes the location information received from the control command device 20 to the guidance display device 40 inside the vehicle corresponding to the car information. As described above, the location information is periodically transmitted from the control command device 20, so the beacon device 30 also periodically distributes the location information to the guidance display device 40 inside the vehicle corresponding to the car information. Furthermore, when the beacon device 30 receives an emergency guidance command from the control command device 20, it distributes the emergency guidance command to the guidance display device 40 inside the vehicle corresponding to the car information. Since the emergency guidance command is transmitted from the control command device 20 when an emergency occurs on the train 70, the beacon device 30 distributes the emergency guidance command to the guidance display device 40 inside the vehicle corresponding to the car information only when it receives an emergency guidance command from the control command device 20. Note that although the illustration is simplified in FIG. 1 , the train 70 is provided with at least as many beacon devices 30 as there are cars constituting the train 70, and at least one beacon device 30 is installed in each car.

[0014] The guidance display device 40 receives location information from the beacon device 30. Furthermore, when an emergency guidance command is transmitted from the beacon device 30, the guidance display device 40 receives the emergency guidance command. The guidance display device 40 transmits the received location information, identification information for identifying the guidance display device 40, user attributes indicating the type of person being assisted or whether the user is able-bodied and capable of assisting the person being assisted, and information indicating whether the emergency guidance command was received to the location information management device 50 as user information. The type of person being assisted may indicate, for example, pregnant women, elderly people, injured people, visually impaired people, etc. The user of the guidance display device 40 registers the user attributes to be included in the user information transmitted from the guidance display device 40, for example, during initial setup after installing an application for operating as the guidance display device 40 on a smartphone. After initial setup, the user of the guidance display device 40 can update the registered user attributes whenever their user attributes change.

[0015] Furthermore, when the guidance display device 40 receives an assistance request guide, which will be described later, transmitted from the position information management device 50, the guidance display device 40 displays the contents of the assistance request guide. Specifically, the guidance display device 40 displays at least information on the type of assistance target, i.e., the person being assisted, as the contents of the assistance request guide. This allows a user of the guidance display device 40 who has confirmed the contents of the assistance request guide displayed on the guidance display device 40 to help nearby people being assisted who have difficulty evacuating on their own to evacuate. Note that, although the present embodiment specifically describes a case in which the guidance display device 40 displays the contents of the assistance request guide, the guidance display device 40 may provide audio guidance on the contents of the assistance request guide, or a device separate from the guidance display device 40 may provide audio guidance on the contents of the assistance request guide.

[0016] In this embodiment, it is assumed that the guidance display device 40 directly transmits and receives information to and from the location information management device 50. However, the communication method between the guidance display device 40 and the location information management device 50 is not limited to this. The guidance display device 40 may transmit and receive information to and from the location information management device 50 via a communication device (not shown) installed on the train 70. In this case, a load is placed on the equipment installed on the train 70, i.e., the communication device (not shown). However, since the location information management device 50 can receive user information to a certain extent in a lump, the load can be reduced compared to receiving user information individually from each guidance display device 40. Because the location information management device 50 targets multiple trains 70, reducing the load on the location information management device 50 is also effective for the assistance request system 10. Communication between the guidance display device 40 and the location information management device 50, whether direct communication or indirect communication, may use a public network or a dedicated network.

[0017] When the location information management device 50 receives from the guidance display device 40 information indicating whether an emergency guidance command has been received and user information whose user attribute indicates a person being assisted, the location information management device 50 identifies an assistance-requesting able-bodied person who can assist the person being assisted. The assistance-requesting able-bodied person who can assist the person being assisted is the user of the guidance display device 40 that transmitted the information indicating whether an emergency guidance command has been received and whose user attribute indicates a person being able-bodied. The location information management device 50 transmits an assistance-requesting guide requesting assistance, i.e., support, for the person being assisted, to the guidance display device 40 used by the identified assistance-requesting able-bodied person.

[0018] FIG. 2 is a second diagram illustrating a configuration example of the assistance request system 10 according to the first embodiment. FIG. 1 illustrates a state in which an emergency information command has not been transmitted from the control command device 20 and the location information managing device 50 has received user information indicating that an emergency information command has not been received. In contrast, FIG. 2 illustrates a state in which an emergency information command has been transmitted from the control command device 20 and the location information managing device 50 has received user information indicating that an emergency information command has been received. In the state illustrated in FIG. 2, the location information managing device 50 identifies an assistance target and transmits an assistance request notification indicating that assistance is requested to the guidance display device 40 used by the able-bodied person requesting assistance, i.e., guidance display device 40a. Note that the location information managing device 50 may or may not notify the guidance display device 40 used by the person being assisted, i.e., guidance display device 40b, that there is no assistance request and that there is no assistance target, i.e., no person being assisted, other than the user of guidance display device 40b.

[0019] 1 and 2, the location information managing device 50 includes a communication unit 51 and a control unit 52. The communication unit 51 receives user information from the guidance display device 40 and transmits an assistance request guide to the guidance display device 40. The control unit 52 identifies an assistance-requesting able-bodied person who is able to assist the person being assisted, and generates the assistance-request guide. In the location information managing device 50, the communication unit 51 performs the operation of sending and receiving information to and from the guidance display device 40, and the control unit 52 performs all other operations.

[0020] The communication unit 51 receives user information from the guidance display device 40 used by a user riding on the train 70, including location information including train formation information and car information on the train 70, identification information of the guidance display device 40, and, if the user using the guidance display device 40 is an assisted person, a user attribute indicating the type of the assisted person or an able-bodied person who can assist the assisted person, and information on whether an emergency guidance command indicating the occurrence of an emergency that requires evacuation action by the user riding on the train 70 has been received. When the communication unit 51 receives information indicating whether an emergency guidance command has been received and the user attribute indicates an assisted person, the control unit 52 identifies an assistance-requesting able-bodied person who can assist the assisted person, and generates an assistance-requesting guide requesting assistance for the assisted person to the guidance display device 40a used by the identified assistance-requesting able-bodied person, and causes the communication unit 51 to transmit the assistance-requesting guide.

[0021] In the location information managing device 50, the control unit 52 may previously store support information in which support details for the assisted person are set according to the type of the assisted person and the type of emergency indicated in the emergency guidance command. For example, if the type of emergency indicated in the emergency guidance command is a fire and the type of the assisted person is a visually impaired person, the support details may be for the assistance-requesting able-bodied person to speak to the visually impaired person and urge them to take a position that avoids inhaling smoke. In this way, the support details are set for each combination of the type of the assisted person and the type of emergency. Note that the support details do not need to be different for each combination of the type of the assisted person and the type of emergency; they may be the same for some combinations. The control unit 52 determines the support details for the assisted person based on the type of the assisted person included in the user information and the type of emergency indicated in the emergency guidance command, and generates an assistance-request guide including the determined support details. In the location information managing device 50, the communication unit 51 transmits the assistance-request guide including the support details generated by the control unit 52 to the guide display device 40a used by the assistance-requesting able-bodied person. This allows the guidance display device 40a to display assistance-requesting information to an assistance-requesting able-bodied person using the guidance display device 40a. As a result, the assistance-requesting able-bodied person who confirms the assistance-requesting information displayed on the guidance display device 40a can provide assistance to nearby people being assisted.

[0022] The above is the division of roles between the communication unit 51 and the control unit 52 in the location information managing device 50. The following description will be centered on the location information managing device 50.

[0023] The assistance-requesting guidance generated by the position information management device 50 may include information on the type of emergency situation and the type of person being assisted indicated in the emergency guidance command. This allows the assistance-requesting able-bodied person who checks the assistance-requesting guidance displayed on the guidance display device 40a to start providing assistance with prior knowledge of the details of the emergency situation that is currently occurring and the type of person being assisted.

[0024] Here, it is conceivable that there are multiple candidates for assistance-requesting able-bodied individuals who can assist the person being assisted on the train 70. If the location information management device 50 transmits an assistance-requesting notice to all of the candidate assistance-requesting able-bodied individuals who can assist the person being assisted, this may cause confusion on the train 70. Furthermore, if the location information management device 50 transmits an assistance-requesting notice to a candidate assistance-requesting able-bodied individual who is far from the person being assisted, this may also cause confusion on the train 70. Therefore, when there are multiple candidates for assistance-requesting able-bodied individuals, the location information management device 50 may prioritize a candidate assistance-requesting able-bodied individual who is close to the person being assisted and transmit the assistance-requesting notice to the guidance display device 40a used by the candidate assistance-requesting able-bodied individual. This allows the location information management device 50 to avoid unnecessary confusion on the train 70. Furthermore, the able-bodied individual requesting assistance can quickly begin assisting the person being assisted.

[0025] Although the case where the location information managing device 50 transmits an assistance-requesting guide to an assistance-requesting able-bodied person has been described, the location information managing device 50 may receive user information, and if the user information indicates whether an emergency guidance command has been received, the location information managing device 50 may transmit a guide indicating that assistance is not required to the guide display device 40a used by an able-bodied person who does not transmit the assistance-requesting guide, even if there is an assisted person present, the location information managing device 50 may transmit a guide indicating that assistance is not required to the guide display device 40a used by an able-bodied person who is far from the assisted person. In this way, the location information managing device 50 can avoid a situation where an assistance-requesting person who is waiting in anticipation of receiving the assistance-requesting guide is delayed in evacuation.

[0026] The location information managing device 50 may provide a reward to an assistance-requesting able-bodied person who has provided assistance to an assisted person. Regarding a method for identifying an assistance-requesting able-bodied person who has provided assistance to an assisted person, the location information managing device 50 can determine that assistance has been provided when a response such as acceptance is obtained from the assistance-requesting able-bodied person who has confirmed the assistance-request guidance, but the identification method is not limited to this. As a reward, the location information managing device 50 may provide a coupon to the assistance-requesting able-bodied person who has provided assistance, for example, based on the user attributes registered at the time of initial configuration of the guidance display device 40.

[0027] FIG. 3 is a sequence diagram showing the operation of the assistance request system 10 according to the first embodiment. In the assistance request system 10, the guidance display device 40 accepts registration of user attributes from the user, for example, during initial setup after installation of an application (step S1). The control command device 20 transmits location information to the beacon device 30 (step S2). The beacon device 30 distributes the location information to the guidance display device 40 in the vehicle (step S3). The guidance display device 40 adds identification information, user attributes, and information indicating that an emergency guidance command has not been received to the received location information (step S4), and transmits the information as user information to the location information management device 50 (step S5). The location information management device 50 uses the location information included in the user information received from the guidance display device 40 to manage user information for each location, specifically for each train 70, and further for each car of each train 70 (step S6).

[0028] The control command device 20 transmits an emergency guidance command to the beacon device 30 (step S7). The beacon device 30 distributes the emergency guidance command to the guidance display device 40 in the vehicle (step S8). When the guidance display device 40 receives the emergency guidance command, it adds identification information, user attributes, and information indicating that an emergency guidance command has been received to the most recent location information it received last time (step S9), and transmits the user information to the location information management device 50 (step S10). The location information management device 50 determines whether or not the user attribute of the user being assisted is included in the multiple pieces of user information it has received (step S11). If there is no user information with the user attribute of the user being assisted (step S11: No), the location information management device 50 terminates its operation.

[0029] If there is user information whose user attribute is a person being assisted (step S11: Yes), the position information managing device 50 identifies an assistance-requesting able-bodied person who is able-bodied and who is able to assist a person being assisted from the user information whose user attribute is an able-bodied person (step S12). The position information managing device 50 transmits an assistance-requesting guide to the guidance display device 40a, which is the guidance display device 40 used by the identified assistance-requesting able-bodied person (step S13). The guidance display device 40a used by the assistance-requesting able-bodied person displays the received assistance-requesting guide (step S14). As a result, the assistance-requesting able-bodied person identified by the position information managing device 50 can assist a nearby person being assisted by checking the content of the assistance-requesting guide displayed on the guidance display device 40a.

[0030] Next, the hardware configuration of the assistance request system 10 according to the first embodiment will be described. In the assistance request system 10, the control command device 20, the beacon device 30, the guidance display device 40, and the location information management device 50 are realized by processing circuits. The processing circuit may be a memory that stores a program and a processor that executes the program stored in the memory, or may be dedicated hardware. The processing circuit is also called a control circuit.

[0031] FIG. 4 is a diagram illustrating an example of the configuration of the processing circuit 90 of the assistance request system 10 according to the first embodiment, when the processing circuit is realized by a processor 91 and a memory 92. The processing circuit 90 illustrated in FIG. 4 is a control circuit and includes a processor 91 and a memory 92. When the processing circuit 90 is configured with the processor 91 and the memory 92, each function of the processing circuit 90 is realized by software, firmware, or a combination of software and firmware. The software or firmware is written as a program and stored in the memory 92. The processing circuit 90 realizes each function by having the processor 91 read and execute the program stored in the memory 92. That is, the processing circuit 90 includes the memory 92 for storing a program that results in the processing of the assistance request system 10 being executed. This program can also be said to be a program that causes the assistance request system 10 to execute each function realized by the processing circuit 90. This program may be provided by a storage medium on which the program is stored, or by other means such as a communication medium.

[0032] The program includes a first step in which the control command device 20 transmits position information including train formation information and car number information of the train 70, and can transmit an emergency guidance command indicating the occurrence of an emergency requiring evacuation action by users on the train 70; a second step in which the beacon device 30 distributes the position information received from the control command device 20 to the inside of a car corresponding to the car number information, and distributes the emergency guidance command to the inside of the car when receiving the emergency guidance command from the control command device 20; and a second step in which the guidance display device 40 receives the position information from the beacon device 30, and when the emergency guidance command is distributed from the beacon device 30, receives the emergency guidance command, and transmits the position information, identification information, and, if the user using the device is a person requiring care, It can also be said that this is a program that causes the assistance request system 10 to execute the following steps: a third step of transmitting user information that indicates the type of person being assisted or a user attribute that indicates a healthy person who can assist the person being assisted, and information on whether an emergency guidance command has been received; a fourth step of, when the location information management device 50 receives user information that indicates that the information on whether an emergency guidance command has been received has been received and the user attribute indicates a person being assisted, identifying an assistance-requesting healthy person from the healthy people who can assist the person being assisted, and transmitting an assistance-request guide to the guidance display device 40a used by the identified assistance-requesting healthy person, requesting assistance for the person being assisted; and a fifth step of, when the guidance display device 40a receives the assistance-request guide, displaying the contents of the assistance-request guide.

[0033] Here, the processor 91 is, for example, a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP (Digital Signal Processor), etc. Furthermore, the memory 92 is, for example, a non-volatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable ROM), or an EEPROM (registered trademark) (Electrically EPROM), a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD (Digital Versatile Disc).

[0034] FIG. 5 is a diagram illustrating an example of the configuration of the processing circuit 93 in the assistance request system 10 according to the first embodiment, when the processing circuit is realized by dedicated hardware. The processing circuit 93 illustrated in FIG. 5 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. The processing circuit 93 may be partially realized by dedicated hardware and partially realized by software or firmware. In this way, the processing circuit 93 can realize each of the above-described functions by dedicated hardware, software, firmware, or a combination thereof.

[0035] As described above, according to this embodiment, in the assistance request system 10, the guidance display device 40 receives location information from the beacon device 30, and receives the emergency guidance command when it is distributed from the beacon device 30. The guidance display device 40 transmits the location information, identification information of the guidance display device 40, and if the user using the guidance display device 40 is a person receiving assistance, the type of the person receiving assistance or a user attribute indicating a person who is able-bodied and can assist the person receiving assistance, and information on whether an emergency guidance command has been received to the location information management device 50. When the location information management device 50 receives user information indicating that an emergency guidance command has been received and the user attribute indicates a person receiving assistance, the location information management device 50 identifies an assistance-requesting able-bodied person who can assist the person receiving assistance from the able-bodied person, and transmits an assistance-request guide requesting assistance for the person receiving assistance to the guidance display device 40a used by the identified assistance-requesting able-bodied person. The guidance display device 40a that receives the assistance-request guide displays the contents of the assistance-request guide.

[0036] As a result, the assistance request system 10 can request assistance from able-bodied persons who are able to provide assistance to the person being assisted who needs assistance. Even if an emergency requiring evacuation occurs while on board the train 70, the assistance request system 10 can avoid a situation in which the person being assisted, who has difficulty taking evacuation action on his or her own, is delayed in evacuation from the train 70.

[0037] Embodiment 2 In the second embodiment, a case will be described in which the assistance request system 10 uses a camera, a display device, and the like installed on the train 70.

[0038] Fig. 6 is a diagram showing an example of the configuration of an assistance request system 10 according to embodiment 2. The assistance request system 10 shown in Fig. 6 is configured by adding a camera 31 and a display device 32 to the assistance request system 10 shown in Fig. 2.

[0039] The camera 31 is installed on the train 70 and captures images of the interior of the vehicle. In each vehicle of the train 70, the camera 31 captures images that enable identification of users on board the train 70, such as whether they are using a wheelchair or crutches. The images captured by the camera 31 may be still images or moving images. The camera 31 transmits image information obtained by capturing images to the location information management device 50.

[0040] The display device 32 displays information for users riding on the train 70. The display device 32 is installed, for example, above or beside the door of the train 70. The display device 32 is a device that displays destinations, stops, and the like to users during normal operation of the train 70.

[0041] The location information management device 50 determines at least one of the support content and the number of able-bodied persons requesting assistance based on the interior status of the vehicle captured by the camera 31. For example, if the user attribute included in the user information received from the guidance display device 40b is a person receiving assistance and the type of the person receiving assistance is an injured person, the location information management device 50 references image information from the camera 31 capturing the interior of the vehicle identified by the formation and car number indicated by the location information included in the user information. If the location information management device 50 can recognize from the image information from the camera 31 that the person receiving assistance is an injured person using crutches or an injured person using a wheelchair, it can appropriately change the support content, the number of able-bodied persons requesting assistance, and the like, depending on the condition of the person receiving assistance. In this way, by using the image information from the camera 31, the location information management device 50 can determine support content that is more in line with the actual situation than in the first embodiment.

[0042] The position information management device 50 may use image information from the camera 31 to identify a person being assisted who does not have a guidance display device 40, identify a able-bodied person requesting assistance from able-bodied people nearby, and transmit an assistance-request guidance message. Not all of the persons being assisted who board the train 70 necessarily have a guidance display device 40. Therefore, even if the position information management device 50 cannot identify a person being assisted from the user information received from the guidance display device 40, if the position information management device 50 can identify a able-bodied person from the image information from the camera 31, it may take the same action as when it receives user information of a person being assisted from the guidance display device 40.

[0043] The location information managing device 50 may also display the content of the assistance-requesting notice on a display device 32 installed near the person being assisted or the assistance-requesting able-bodied person. Even if the location information managing device 50 transmits the assistance-requesting notice to the guidance display device 40a used by the identified assistance-requesting able-bodied person, it is possible that the assistance-requesting able-bodied person is not looking at the guidance display device 40a, i.e., a smartphone on which an application for operating as the guidance display device 40 is installed. Therefore, the location information managing device 50 can prompt the assistance-requesting able-bodied person to assist the person being assisted by displaying the content of the assistance-requesting notice on a display device 32 installed near the person being assisted or the assistance-requesting able-bodied person. Note that, from the perspective of protecting the privacy of the person being assisted, the location information managing device 50 may transmit different content of the assistance-requesting notice to the guidance display device 40a used by the assistance-requesting able-bodied person from the content of the assistance-requesting notice displayed on the display device 32. In this way, by using the display device 32, the position information managing device 50 can more reliably transmit the assistance request guidance to the user riding on the train 70 compared to the first embodiment.
