Description

Location information management device, evacuation direction guidance system, and evacuation direction identification method

[0001] The present disclosure relates to a location information management device, an evacuation direction guidance system, and an evacuation direction identification method used when evacuating users on a train.

[0002] Conventionally, there are systems that support the evacuation of users on trains in the event of a disaster occurring while the train is in operation, etc. For example, Patent Document 1 discloses a technology in which an evacuation support system, in which a model pattern for evacuation support is preset, guides users to evacuate in accordance with the model pattern and suppresses the spread of the fire when a fire suddenly breaks out in a tunnel while the train is traveling through the tunnel.

[0003] Japanese Patent Application Laid-Open No. 2004-74858

[0004] In subways and other trains, where there is no evacuation space between the tunnel and the train, when train users disembark and evacuate, they must exit through the emergency exits at the front of both leading cars. However, the above-mentioned conventional technology does not take into account a situation where two trains are running between the same stations within a tunnel. As a result, if users on a first train try to evacuate toward a second train and users on the second train try to evacuate toward the first train, the users end up crowded together in the tunnel, which can actually make it take longer to complete the evacuation.

[0005] The present disclosure has been made in consideration of the above, and aims to provide a location information management device that can appropriately identify the evacuation direction taking into account the positions of other trains when evacuating users of a train in a tunnel.

[0006] In order to solve the above-mentioned problems and achieve the objectives, the location information management device disclosed herein is characterized by comprising a communication unit that receives train information including train formation information including the formation number of a train traveling within a tunnel, an evacuation guidance command indicating that an incident has occurred that requires evacuation for users on the train, and information on the station ahead in the direction of train travel, the station behind the train in the opposite direction of train travel, and the distance the train travels between stations, and a control unit that identifies the evacuation direction in which users on the train will evacuate based on the train information and the location information of multiple trains, generates evacuation direction guidance indicating the identified evacuation direction, and transmits it from the communication unit.

[0007] The location information management device disclosed herein has the advantage of being able to appropriately identify the evacuation direction in consideration of the positions of other trains when evacuating users of a train inside a tunnel.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A location information management device, an evacuation direction guidance system, and an evacuation direction identification method according to embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0010] Embodiment 1. FIG. 1 is a first diagram illustrating a configuration example of an evacuation direction guidance system 10 according to Embodiment 1. The evacuation direction guidance system 10 includes a control command device 20, a beacon device 30, a guidance display device 40, a location information management device 50, and an operation management device 60. In the evacuation direction guidance system 10, the control command device 20 and the beacon device 30 are installed on a train 70. The guidance display device 40 is used by a user aboard the train 70 and can be used inside the train 70 and outside the train 70 in conjunction with the user's actions. The guidance display device 40 is a mobile terminal such as a smartphone on which an application that performs the operations described below is installed, but it may also be a dedicated terminal. The location information management device 50 and the operation management device 60 are servers or the like installed in a ground system (not shown) that manages the operation of the train 70. In this embodiment, the train 70 is used in tunnels such as subways, and since there is no evacuation space between the tunnel and the cars of the train 70, it is assumed that when users of the train 70 disembark and evacuate, they will disembark through the emergency exits at the front of both leading cars of the train 70.

[0011] The control command device 20 transmits train information including the train set number of the train 70 traveling through the tunnel, an evacuation guidance command indicating that an event requiring evacuation of a user aboard the train 70 has occurred, information on the forward station in the direction of travel of the train 70, the rear station opposite the direction of travel of the train 70, and the distance traveled by the train 70 between stations. The train set number is identification information for identifying each of the multiple trains 70. The train set information may include, for example, car number information indicating the position of the car on the train 70, such as which car (cars 1 to 10) the user is riding in if the train 70 is a 10-car train. An event requiring evacuation of a user aboard the train 70 may be, for example, a fire occurring on the train 70 or in the tunnel. However, the event may also be an event other than a fire, as long as the user aboard the train 70 disembarks from the train 70 and evacuates to the nearest station. The forward station is the next station the train 70 will stop at or pass through, and the rear station is the station the train 70 last stopped at or passed through.

[0012] The train information transmitted from the control command device 20 is assumed to be used by the location information management device 50 when identifying the evacuation direction of users aboard each train 70. Therefore, the control command device 20 may not transmit train information or may transmit train information that does not include an evacuation guidance command when no situation has occurred that requires evacuation for users aboard the train 70. Alternatively, the control command device 20 may transmit all train information other than the evacuation guidance command and transmit only the evacuation guidance command separately. Alternatively, the control command device 20 may include information on the presence or absence of an evacuation guidance command in the train information. The control command device 20 transmits an evacuation guidance command to the beacon device 30 when a train crew member or the like of the train 70 who detects the occurrence of a situation that requires evacuation for users aboard the train 70 operates a button installed on the driver's cab or the like. Depending on the type of evacuation guidance command, the control command device 20 may automatically determine the occurrence of a situation that requires evacuation for users aboard the train 70 and transmit the evacuation guidance command to the beacon device 30. This allows the control command device 20 to quickly transmit an evacuation guidance command or train information including an evacuation guidance command to the beacon device 30.

[0013] The beacon device 30 distributes the train information received from the control command device 20 to the guidance display device 40 inside the train 70. Although the illustration is simplified in Fig. 1 , the train 70 is provided with at least as many beacon devices 30 as the number of cars constituting the formation of the train 70, and at least one beacon device 30 is installed in each car. When train information other than the evacuation guidance command is transmitted collectively from the control command device 20 and only the evacuation guidance command is transmitted separately, the beacon device 30 may distribute the train information other than the evacuation guidance command collectively and distribute only the evacuation guidance command separately, or may distribute the train information other than the evacuation guidance command and the evacuation guidance command together as train information.

[0014] The guidance display device 40 transmits train information received from the beacon device 30 to the location information management device 50 while the user is aboard the train 70. When the beacon device 30 distributes train information other than the evacuation guidance command together and separately distributes only the evacuation guidance command, the guidance display device 40 may transmit the train information other than the evacuation guidance command together and separately transmit only the evacuation guidance command, or may transmit the train information other than the evacuation guidance command and the evacuation guidance command together as train information. Furthermore, when evacuation direction guidance, which will be described later, is transmitted from the location information management device 50 and the guidance display device 40 receives the evacuation direction guidance, the guidance display device 40 displays the content of the evacuation direction guidance, i.e., the evacuation direction. As a result, a user of the guidance display device 40 who has confirmed the content of the evacuation direction guidance displayed on the guidance display device 40 can evacuate in an appropriate direction if an incident occurs that requires evacuation for the user aboard the train 70.

[0015] 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 train information to a certain extent in a consolidated manner, the load can be reduced compared to when train information is received individually from each guidance display device 40. Since 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 evacuation direction guidance 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.

[0016] The traffic management device 60 manages the location information of each formation, i.e., each train 70, and transmits the location information of each train 70 to the location information management device 50. The traffic management device 60 can grasp the location information of each train 70 from the location information of each train 70 that is periodically transmitted from each train 70.

[0017] The position information management device 50 identifies an evacuation direction for a user aboard the train 70, based on the train information received from the guidance display device 40 and the position information of a plurality of trains 70 received from the traffic management device 60. The position information management device 50 transmits evacuation direction guidance indicating the identified evacuation direction to the guidance display device 40. In the present embodiment, when a first train and a second train are present on a track in the same direction of travel between a first station and a second station within a tunnel, the position information management device 50 identifies the direction of the first station where the second train is not present as the evacuation direction for a user aboard the first train, and identifies the direction of the second station where the first train is not present as the evacuation direction for a user aboard the second train. The position information management device 50 transmits evacuation direction guidance indicating each evacuation direction to the guidance display device 40 used by a user aboard the first train and the guidance display device 40 used by a user aboard the second train.

[0018] FIG. 2 is a diagram illustrating an example of an evacuation direction identified by the location information management device 50 of the evacuation direction guidance system 10 according to the first embodiment. In FIG. 2 , train 70a corresponds to the first train, train 70b corresponds to the second train, station 80a corresponds to the first station, and station 80b corresponds to the second station. By identifying the evacuation direction of each train 70 in this manner, the location information management device 50 can appropriately identify the evacuation direction based on the positions of other trains 70 when evacuating a user of the train 70 in a tunnel. Note that while FIG. 1 illustrates the evacuation direction as an "upward direction," the specific guidance method is not critical as long as the user can correctly understand the evacuation direction. Specific evacuation method guidance methods include an "upward direction," a "downward direction," the "direction of travel of the train 70," a "direction opposite to the direction of travel of the train 70," a "direction toward the next station," a "direction toward the station where the train last stopped," a "direction toward the destination or terminal station of the train 70," and a "direction toward the starting station of the train 70."

[0019] 1 , the location information management device 50 includes a communication unit 51 and a control unit 52. The communication unit 51 receives train information from the guidance display device 40 and transmits evacuation direction guidance to the guidance display device 40. The communication unit 51 also receives location information of each train 70 from the traffic management device 60. The control unit 52 identifies the evacuation direction of a user riding on the train 70 and generates evacuation direction guidance. In the location information management device 50, the communication unit 51 transmits and receives information between the guidance display device 40 and the traffic management device 60, and the control unit 52 performs all other operations.

[0020] The communication unit 51 receives train information including the train formation number of the train 70 traveling in the tunnel, an evacuation guidance command indicating that an event has occurred requiring evacuation for users aboard the train 70, and train information including information on the stations ahead in the direction of travel of the train 70, the stations behind the train 70 in the opposite direction of travel of the train 70, and the distance traveled between stations of the train 70. The control unit 52 identifies the evacuation direction in which users aboard the train 70 will evacuate based on the train information and the position information of the multiple trains 70, generates evacuation direction guidance indicating the identified evacuation direction, and causes the communication unit 51 to transmit the evacuation direction guidance.

[0021] Although the description has been given of a case in which the control unit 52 of the position information management device 50 acquires the position information of each train 70 via the communication unit 51 from the traffic management device 60 that manages the position information of the trains 70, the present invention is not limited to this. The control unit 52 of the position information management device 50 can also calculate the position information of each train 70 from the train information received from the guidance display device 40. The train information received from the guidance display device 40 includes information on the preceding station, the following station, and the running distance between stations, and therefore the control unit 52 of the position information management device 50 can use this information to calculate the position information of the train 70 indicated in the train information.

[0022] Furthermore, the control unit 52 of the location information management device 50 may further display the contents of the evacuation direction guidance on a display device installed on the train 70 for displaying information targeted at users aboard the train 70. FIG. 3 is a second diagram illustrating a configuration example of the evacuation direction guidance system 10 according to the first embodiment. The evacuation direction guidance system 10 illustrated in FIG. 3 is configured by adding a display device 32 installed in the train 70 to the evacuation direction guidance system 10 illustrated in FIG. 1 . The display device 32 displays information targeted at users aboard the train 70. The display device 32 is installed, for example, above or beside the door of the train 70. The display device 32 displays information such as destinations and stops to the user during normal operation of the train 70. Even if the communication unit 51 of the location information management device 50 transmits evacuation direction guidance to the guidance display device 40, it is possible that the user is not looking at the guidance display device 40, i.e., a smartphone on which an application for operating as the guidance display device 40 is installed. Therefore, the control unit 52 of the location information management device 50 can urge users to evacuate by displaying the content of the evacuation direction guidance on the display device 32 installed in the carriage of the train 70. Note that the control unit 52 of the location information management device 50 may make the content of the evacuation direction guidance transmitted to the guidance display device 40 different from the content of the evacuation direction guidance displayed on the display device 32, taking into consideration the size of the display screen, ease of reading the characters, etc. In this way, the control unit 52 of the location information management device 50 can more reliably convey evacuation direction guidance to users riding on the train 70 by further using the display device 32.

[0023] Note that when the train 70 is operated as a subway, a third rail system may be used as a power supply system for the train 70. For users to disembark and evacuate from the train 70 that is powered by a third rail system, the power supply via the third rail system must be stopped to ensure the users' safety. If the power supply to the train 70 is stopped, the display device 32 and other devices may become unusable. However, in the present embodiment, the evacuation direction guidance system 10 transmits evacuation direction guidance not only to the display device 32 but also to the guidance display device 40. Therefore, even in a situation where the power supply to the train 70 is stopped due to the user's evacuation or a disaster, making the display device 32 unusable, the evacuation direction guidance system 10 can communicate evacuation directions to users aboard the train 70 by using the guidance display device 40.

[0024] Furthermore, the control unit 52 of the location information management device 50 may cause the communication unit 51 to transmit evacuation direction guidance to the guidance display device 40 used by users riding in each car, starting with the car closest to the evacuation direction. As described above, when users evacuate from the train 70, they disembark from the train 70 through the emergency exit located in front of the leading car in the evacuation direction. It is considered that users do not disembark from the emergency exit quickly. Therefore, if users of the train 70 move toward the emergency exit all at once, users may crowd around the car where the emergency exit is installed, potentially causing a secondary disaster. Therefore, for example, when evacuating users from the emergency exit in the first car of the train 70, the control unit 52 of the location information management device 50 first causes the communication unit 51 to transmit evacuation direction guidance to the guidance display device 40 used by users in the first car. Control unit 52 of location information management device 50 controls the timing of transmitting evacuation direction guidance from communication unit 51, such that communication unit 51 transmits evacuation direction guidance to guidance display device 40 used by users in car 2 around the time when the evacuation of users in car 1 is complete, and communication unit 51 transmits evacuation direction guidance to guidance display device 40 used by users in car 3 around the time when the evacuation of users in car 2 is complete. In this way, control unit 52 of location information management device 50 can avoid a situation in which users gather and become crowded near cars where emergency exits are installed.

[0025] The operation of opening the emergency exit of the train 70 may be performed by the crew of the train 70, or if the train 70 is an automatically operated train, it may be remotely operated by a ground system such as the position information management device 50 and the operation management device 60. In the evacuation direction guidance system 10, the ground system such as the position information management device 50 and the operation management device 60 may be configured to remotely open the emergency exit of the train 70 even if the train 70 is not an automatically operated train and a crew is on board.

[0026] FIG. 4 is a sequence diagram illustrating the operation of the evacuation direction guidance system 10 according to the first embodiment. In the evacuation direction guidance system 10, the traffic management device 60 transmits the position information of each train 70 to the position information management device 50 (step S1). The control unit 52 of the position information management device 50 receives the position information of each train 70 via the communication unit 51 (step S2). The control command device 20 transmits train information including information on the train formation, an evacuation guidance command, the preceding station, the following station, and the running distance between stations to the beacon device 30 (step S3). Upon receiving the train information including the train formation information, the evacuation guidance command, the preceding station, the following station, and the running distance between stations, the beacon device 30 distributes the train information to the guidance display device 40 inside the train 70 (step S4). Upon receiving the train information including the information on the train formation information, the evacuation guidance command, the preceding station, the following station, and the running distance between stations, the guidance display device 40 transmits the train information to the position information management device 50 (step S5).

[0027] When the control unit 52 of the location information management device 50 receives train information including information on train formations, evacuation guidance commands, information on preceding stations, following stations, and information on inter-station running distances via the communication unit 51 (step S6), it identifies an evacuation direction for users aboard the train 70 based on the received train information and the location information of each train 70 (step S7). The control unit 52 of the location information management device 50 then causes the communication unit 51 to transmit evacuation direction guidance indicating the evacuation direction to the guidance display device 40 used by the users aboard the train 70 (step S8). When the guidance display device 40 receives the evacuation direction guidance (step S9), it displays the evacuation direction guidance (step S10). As a result, the users of the guidance display device 40 can evacuate in the evacuation direction identified by the location information management device 50 by checking the content of the evacuation direction guidance displayed on the guidance display device 40.

[0028] Next, the hardware configuration of the evacuation direction guidance system 10 according to the first embodiment will be described. In the evacuation direction guidance system 10, the control command device 20, the beacon device 30, the guidance display device 40, the location information management device 50, and the traffic management device 60 are realized by processing circuits. The processing circuit may be a memory that stores programs and a processor that executes the programs stored in the memory, or may be dedicated hardware. The processing circuit is also called a control circuit.

[0029] FIG. 5 is a diagram illustrating an example of the configuration of a processing circuit 90 in the evacuation direction guidance 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. 5 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 processor 91 reads and executes the program stored in the memory 92 to realize each function of the processing circuit 90. That is, the processing circuit 90 includes the memory 92 for storing a program that results in the processing of the evacuation direction guidance system 10. This program can also be said to be a program that causes the evacuation direction guidance 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.

[0030] The above program can also be said to be a program that causes the evacuation direction guidance system 10 to execute the following steps: a communication step in which the communication unit 51 receives train formation information including the formation number of the train 70 traveling within the tunnel, an evacuation guidance command indicating that an incident has occurred that requires evacuation for users riding on the train 70, and train information including the station ahead in the direction of travel of the train 70, the station behind the train 70 in the opposite direction of travel of the train 70, and information on the distance traveled between stations by the train 70; and a control step in which the control unit 52 identifies the evacuation direction in which users riding on the train 70 will evacuate based on the train information and the position information of multiple trains 70, generates evacuation direction guidance indicating the identified evacuation direction, and transmits it from the communication unit 51.

[0031] Here, the processor 91 is, for example, a CPU (Central Processing Unit), a processing device, an arithmetic unit, a microprocessor, a microcomputer, or a DSP (Digital Signal Processor), etc. 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 (Electrically EPROM), a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD (Digital Versatile Disc).

[0032] FIG. 6 is a diagram illustrating an example of the configuration of the processing circuit 93 in the evacuation direction guidance system 10 according to the first embodiment, when the processing circuit is implemented by dedicated hardware. The processing circuit 93 illustrated in FIG. 6 may be, 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 implemented by dedicated hardware and partially implemented 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.

[0033] As described above, according to the present embodiment, in the evacuation direction guidance system 10, the location information management device 50 generates evacuation direction guidance indicating the evacuation direction by identifying the evacuation direction for a user aboard the train 70 based on train information including train formation information, evacuation guidance commands, information on the preceding station, the following station, and the running distance between stations of the train 70, as well as the location information of each train 70, and transmits the generated evacuation direction guidance to the guidance display device 40 used by the user aboard the train 70. In this way, the location information management device 50 can appropriately identify the evacuation direction taking into account the positions of other trains 70 when evacuating a user of the train 70 inside a tunnel. Furthermore, upon receiving the evacuation direction guidance, the guidance display device 40 displays the evacuation direction guidance. As a result, the user of the guidance display device 40 can evacuate in the evacuation direction identified by the location information management device 50 by checking the content of the evacuation direction guidance displayed on the guidance display device 40.

[0034] Embodiment 2 In the first embodiment, the location information management device 50 was able to identify different evacuation directions for users riding on two trains 70 located between stations. In the second embodiment, a case will be described in which different evacuation directions cannot be identified for users riding on two trains 70 located between stations.

[0035] In the second embodiment, the configuration of the evacuation direction guidance system 10 is the same as the configuration of the evacuation direction guidance system 10 of the first embodiment shown in FIG. 1 or 3. In a situation where two trains 70 are present between stations, if the content of the evacuation guidance command prevents users aboard the trains 70 from evacuating to one of the stations due to a fire, flooding, or the like at one of the stations, the control unit 52 of the location information management device 50 must specify the same station, i.e., the same evacuation direction, for users aboard both trains 70. In such a case, the control unit 52 of the location information management device 50 first evacuates users aboard the train 70 that is in the evacuation direction, i.e., closer to a station where evacuation is possible, and then evacuates users aboard the train 70 that is farthest from a station where evacuation is possible, thereby avoiding congestion caused by users disembarking from both trains 70.

[0036] In this embodiment, when a first train and a second train are present on tracks in the same direction of travel between a first station and a second station in a tunnel and evacuation to the second station is not possible, the control unit 52 of the location information management device 50 specifies the direction of the first station where the second train is not present as the evacuation direction for a user riding the first train, and specifies the direction of the first station where the first train is present as the evacuation direction for a user riding the second train. The control unit 52 of the location information management device 50 opens both emergency exits installed at the front and rear of the first train. The control unit 52 of the location information management device 50 transmits evacuation direction guidance from the communication unit 51 to the guidance display device 40 used by the user riding the first train first, and then causes the guidance display device 40 used by the user riding the second train to transmit evacuation direction guidance.

[0037] FIG. 7 is a diagram illustrating an example of evacuation directions identified by the location information management device 50 of the evacuation direction guidance system 10 according to the second embodiment. In FIG. 7 , train 70a corresponds to the first train described above, train 70b corresponds to the second train described above, station 80a corresponds to the first station described above, and station 80b corresponds to the second station described above. By identifying the evacuation directions of each train 70 in this manner, the location information management device 50 can appropriately identify evacuation directions taking into account the positions of other trains 70 when evacuating a user of a train 70 in a tunnel. As illustrated in FIG. 7 , a user aboard the second train 70b will evacuate by passing through the interior of the first train 70a after disembarking from the second train 70b. However, if an evacuation exit in the opposite direction from the first train 70a is also open, the user can evacuate via this evacuation route.

[0038] The configurations shown in the above embodiments are merely examples, and may be combined with other known technologies, or different embodiments may be combined with each other. It is also possible to omit or modify parts of the configurations as long as they do not deviate from the gist of the invention.
