[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An evacuation assistance control device and an evacuation assistance method according to embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0011] [Embodiment] <Evacuation support system> Fig. 1 is a schematic diagram showing an outline of an evacuation support system according to an embodiment. Fig. 2 is a block diagram showing an outline of an evacuation support system including an evacuation support control device according to an embodiment. The evacuation support system 1 supports evacuation within a facility when a disaster occurs. The evacuation support system 1 includes a receiving unit 11, a facility information storage unit 12, a notification unit 18, a communication unit 19, and an evacuation support control device 20.

[0012] The receiving unit 11 is a receiver capable of detecting an indoor position with high accuracy. The receiving unit 11 receives, for example, a signal emitted from a beacon transmitter placed indoors. The receiving unit 11 may be implemented as one of the functions of a terminal device such as a smartphone or wearable device carried by an evacuee. The receiving unit 11 outputs the received signal to the position information collecting unit 22 of the evacuation assistance control device 20.

[0013] The facility information storage unit 12 stores facility information. The facility information includes, for example, information indicating the locations of passageways, stairs, exits, emergency exits, and the like in the facility. The facility information storage unit 12 outputs the stored facility information to the facility information acquisition unit 23 of the evacuation assistance control device 20. The facility information storage unit 12 may be a storage device such as an external server that acquires facility information via a communication function.

[0014] The notification unit 18 is a device that notifies evacuation guidance information to evacuees. The notification unit 18 outputs the evacuation guidance information based on a control signal output from the notification control unit 28 of the evacuation support control device 20. The evacuation guidance information will be described later.

[0015] The notification unit 18 may be, for example, a display including a liquid crystal display or an organic EL (Electro-Luminescence) display used for digital signage, etc., arranged in multiple units within the facility. The notification unit 18 may be, for example, a display unit of a mobile terminal such as a smartphone used by an evacuee. The notification unit 18 displays a video showing evacuation guidance information based on a video signal output from the notification control unit 28 of the evacuation assistance control device 20. The multiple notification units 18 are each capable of reporting different evacuation guidance information.

[0016] The notification unit 18 may be, for example, a plurality of speakers arranged in the facility that output audio such as public address systems. The notification unit 18 may be, for example, a speaker of a mobile device such as a smartphone used by an evacuee. The notification unit 18 outputs audio indicating evacuation guidance information based on an audio signal output from the notification control unit 28 of the evacuation assistance control device 20. The plurality of notification units 18 can each notify different pieces of evacuation guidance information.

[0017] The mobile terminal of the evacuee and the evacuation support system 1 can communicate data by short-range wireless communication such as Bluetooth (registered trademark). The mobile terminal of the evacuee and the evacuation support system 1 are paired. An application is installed on the mobile terminal, which has a function of collecting location information, identification information for identifying the mobile terminal, and the like from the mobile terminal to the evacuation support control device 20.

[0018] The communication unit 19 is a communication unit that can communicate with, for example, a device that transmits disaster information and a mobile terminal carried by an evacuee.

[0019] <Evacuation assistance control device> The evacuation assistance control device 20 supports evacuation within a facility. The evacuation assistance control device 20 is an arithmetic processing device configured, for example, with a CPU (Central Processing Unit) and the like. The evacuation assistance control device 20 executes instructions included in a program stored in a storage unit (not shown). The evacuation assistance control device 20 has a disaster information acquisition unit 21, a location information collection unit 22, a facility information acquisition unit 23, a movement status analysis unit 24, an evacuation guidance information generation unit 25, a notification control unit 28, and a communication control unit 29.

[0020] The disaster information acquisition unit 21 acquires disaster information indicating the occurrence of a disaster within the facility. The disaster information acquisition unit 21 may acquire disaster information transmitted from an external device, such as a device of a facility management company. The disaster information acquisition unit 21 may acquire disaster information input by a facility manager, for example. The disaster information acquisition unit 21 may detect the occurrence of a disaster from sensor data from a fire sensor or the like arranged within the facility, and acquire the detection result as disaster information. The acquisition method of the disaster information acquisition unit 21 is not limited to these.

[0021] The disaster information is information that indicates a disaster that has occurred within a facility and that requires evacuation, and indicates the type, scale, and location of the disaster.

[0022] The location information collection unit 22 collects location information indicating the locations of multiple evacuees within the facility. In this embodiment, the location information collection unit 22 acquires the location information of each evacuee based on the signal acquired by the receiving unit 11.

[0023] The facility information acquisition unit 23 acquires facility information from the facility information storage unit 12 .

[0024] The movement status analysis unit 24 estimates the movement status of multiple evacuees based on at least one of the positions, movement speeds, movement directions, and distances between the evacuees, based on the location information collected by the location information collection unit 22, and divides the multiple evacuees into groups.

[0025] When a disaster occurs, evacuees tend to follow the evacuation behavior of those around them due to conformity bias. As a result, groups may form along evacuation routes within a facility, moving toward the same exit or emergency exit. Therefore, the movement status analysis unit 24 divides multiple evacuees into the above-mentioned groups according to their movement status.

[0026] The movement status analysis unit 24 may group multiple evacuees into the same group if, for example, the locations of the multiple evacuees are within a predetermined range, the movement speeds are within a predetermined speed range, the movement directions are the same, or the distance between the evacuees is equal to or less than a predetermined distance. The movement status analysis unit 24 may group multiple evacuees into the same group if the multiple conditions are satisfied.

[0027] A location within a predetermined range means, for example, being located within a range of several tens of meters in the same passage on the same floor within the facility, or being located within a predetermined distance from an exit or emergency exit within the facility. The movement status analysis unit 24, for example, groups multiple evacuees located within a range of several tens of meters in the same passage on the same floor within the facility. The movement status analysis unit 24 may, for example, group multiple evacuees within the facility according to the distance from the exit or emergency exit.

[0028] The movement speed being within a predetermined speed range means, for example, that the difference in movement speed is within a range of about 1 km / h. For example, the movement status analysis unit 24 groups a plurality of evacuees who are in the same passage on the same floor of the facility and whose movement speed differs by about 1 km / h into one group.

[0029] The movement direction being the same means, for example, heading toward the same exit or emergency exit. The movement status analysis unit 24 groups, for example, a plurality of evacuees who are heading toward the same exit or emergency exit in the same passage on the same floor of the facility.

[0030] The distance between evacuees being equal to or less than a predetermined distance means, for example, that the distance between evacuees is equal to or less than 5 m. For example, the movement status analysis unit 24 groups a plurality of evacuees who are equal to or less than 5 m apart in the same passage on the same floor of the facility into one group.

[0031] The evacuation guidance information generation unit 25 generates evacuation guidance information for each group that guides evacuation routes to an exit or emergency exit within the facility based on the disaster information acquired by the disaster information acquisition unit 21 and the facility information acquired by the facility information acquisition unit 23.

[0032] The evacuation guidance information is information that guides an evacuation route from the current location of an evacuee to an exit or emergency exit that is located in the vicinity of the current location of the evacuee.

[0033] The method of searching for a route from the current location of the evacuee to an exit or emergency exit that is located in the vicinity of the current location of the evacuee can be any known route search method, and is not limited thereto.

[0034] The evacuation guidance information generator 25 generates evacuation guidance information according to at least one of the position, movement speed, and size of a group. Here, the position of a group may be, for example, the center position of the positions of multiple evacuees in the same group, the position of the leading evacuee, or the position of the trailing evacuee, and further, the relationship with the positions of emergency exits, the position of a disaster, or the positions of other groups may be taken into consideration. The movement speed of a group may be, for example, the average movement speed of multiple evacuees in the same group, the movement speed of the slowest evacuee, or the movement speed of the fastest evacuee. The size of a group may be, for example, the distance from the leading evacuee to the trailing evacuee in the same group or the number of evacuees.

[0035] For example, for a group close to an emergency exit, the evacuation guidance information generating unit 25 generates evacuation guidance information to guide the group to evacuate safely and smoothly, including detailed routes to the emergency exit so that the group can quickly reach the emergency exit, as well as lining up instructions to prevent a large number of evacuees from concentrating at the emergency exit at the same time and causing congestion or a crowd avalanche.

[0036] For example, for a group far from an emergency exit, the emergency exit cannot be seen immediately and the group becomes anxious about the future, so the evacuation guidance information generating unit 25 generates evacuation guidance information such as the direction of movement, the status of the evacuation route, and the time required to reach the emergency exit to prevent the group from panicking.

[0037] For example, for a group moving at a high speed, the evacuation guidance information generating unit 25 generates evacuation guidance information such as an appropriate moving speed to reduce the risk of falling or the like.

[0038] For example, for a group moving at a slow speed, the evacuation guidance information generating unit 25 generates evacuation guidance information such as an appropriate moving speed in order to shorten the evacuation time.

[0039] For example, for a large group, the evacuation guidance information generating unit 25 generates evacuation guidance information such as an appropriate distance between evacuees in order to reduce the risk of evacuees pushing against each other or a crowd avalanche.

[0040] For example, for a small group, the evacuation guidance information generating unit 25 generates evacuation guidance information such as an appropriate distance between evacuees so that the evacuees move together without scattering.

[0041] For example, for a group that is far from an emergency exit and close to other preceding groups, the evacuation guidance information generating unit 25 generates evacuation guidance information that guides the group to follow the moving direction and moving speed of the other preceding groups, and generates evacuation guidance information for the other preceding groups to lead the following groups.

[0042] For example, for a group that is far from an emergency exit and is far away from other preceding groups, the evacuation guidance information generating unit 25 generates evacuation guidance information that guides the group to evacuate in a moving direction and at a moving speed that allows the group to safely catch up with other preceding groups.

[0043] The notification control unit 28 controls the evacuation guidance information generated by the evacuation guidance information generating unit 25 to be output to the notification unit 18.

[0044] The notification control unit 28 may change the notification mode for each group. The notification control unit 28 may change the notification mode depending on at least one of the position, moving speed, and size of the group.

[0045] Changing the notification mode means, for example, changing the notification means. For example, this could be a notification mode that notifies on a display or by voice from a speaker, a notification mode that notifies on a display and by voice from a speaker, or a notification mode that notifies on a display and by voice from a speaker. Or, for example, a notification mode that uses the display or speaker of a mobile device of an evacuee.

[0046] Changing the notification mode means, for example, changing the volume of the notification sound from a speaker, outputting the sound repeatedly, and so on.

[0047] For example, the notification control unit 28 may notify a group close to an emergency exit by voice from a speaker, and may notify a group far from the emergency exit by display.

[0048] For example, the notification control unit 28 may notify a group moving at a fast speed by voice from a speaker, and may notify a group moving at a slow speed on a display.

[0049] For example, the notification control unit 28 may notify a large group by voice from a speaker, and may notify a small group by display.

[0050] The notification control unit 28 may change the notification mode depending on the position of the evacuee within the group.

[0051] For example, the notification control unit 28 notifies a group close to an emergency exit of evacuation guidance information so that the group can quickly reach the emergency exit and avoid congestion near the emergency exit or a crowd avalanche. For example, the notification control unit 28 notifies a group close to an emergency exit of detailed evacuation routes to the emergency exit and instructions for lining up by voice from the notification unit 18, or makes repeated announcements from the notification unit 18, or makes announcements at an increased volume from the notification unit 18. For example, the notification may say, "The emergency exit is just around the corner. Please proceed through the emergency exit without panicking," or "The emergency exit is here. Please line up in two lines and take turns passing through the emergency exit."

[0052] For example, the notification control unit 28 notifies the evacuation guidance information to the evacuee at the head of the group through the notification unit 18 in a voice that leads the group. For example, the notification control unit 28 notifies the evacuee at the head of the group through the notification unit 18 in a voice that says, "There are evacuees following behind you. Turn left soon to reach the emergency exit. Please go through the emergency exit without running or stopping," or "There are evacuees following behind you. The emergency exit is here. Line up in two lines and go through the emergency exit in order." In this case, the notification may be made using the display or speaker of the mobile device of the evacuee at the head of the group.

[0053] For example, the notification control unit 28 notifies a group that is far from an emergency exit and close to another preceding group of evacuation guidance information to follow the other preceding group. For example, the notification control unit 28 notifies a group that is far from an emergency exit with a voice guiding the group to follow the preceding group from the notification unit 18. The voice guiding the group to follow is, for example, "Please evacuate following the evacuees in front of you," or "Please stay with the evacuees in front of you without overtaking or pushing them."

[0054] For example, for a group that is far from an emergency exit and is far away from other groups ahead of them, the notification control unit 28 notifies them of evacuation guidance information that guides them to evacuate in a moving direction and at a moving speed that will allow them to safely catch up with other groups ahead of them. For example, for a group that is far from an emergency exit and is far away from other groups ahead of them, the notification control unit 28 notifies them from the notification unit 18 with audio such as, "You're almost to the emergency exit. Increase your walking speed a little and keep walking straight," or "Increase your walking speed a little and keep walking straight. A group of evacuees heading for the emergency exit will be visible ahead."

[0055] When the distance to an exit or emergency exit or the distance to a preceding group changes as a group evacuates, the notification control unit 28 changes the evacuation guidance information and notifies it accordingly. For example, when a group far from an emergency exit approaches the emergency exit, the notification control unit 28 changes the content of the notification to a group close to the emergency exit.

[0056] When a group is large and the distance from the front to the back is long, the notification control unit 28 may issue a voice message such as "Please go straight toward the passage guide light approximately 10 meters ahead" to evacuees near the front, and "Please follow the person in front" to evacuees near the back. The notification control unit 28 may not provide any special voice guidance to evacuees near the middle of the group. In this case, the notification may be issued using the display or speaker of the mobile device of the evacuees near the front and the evacuees near the back of the group.

[0057] FIG. 3 is a diagram showing an example of the movement of evacuees. In the example shown in FIG. 3, passages 211, 212, 213, and 214 intersect at an intersection 219 within the facility. The end of passage 211 opposite the intersection 219 is fire location 201. Emergency exit 202 is located at the end of passage 212 opposite the intersection 219. The end of passage 213 opposite the intersection 219 and the end of passage 214 opposite the intersection 219 are connected to exits located farther away than emergency exit 202. In the example shown in FIG. 3, in passage 212, a group close to emergency exit 202 is group A, and a group close to intersection 219 is group B. In passage 211, a group approaching intersection 219 is group C.

[0058] Group A is a group close to the emergency exit. For this reason, evacuation guidance information such as "If you continue going straight, you will soon reach the emergency exit. Please line up in two lines and take your order and proceed through the emergency exit without rushing" is repeatedly output to Group A from the speaker. Group A is guided to quickly leave the facility through the emergency exit. For evacuee M1 at the head of group A1, the notification unit 18 notifies, for example, with a voice such as "There are evacuees following behind you. If you continue going straight, you will soon reach the emergency exit. Please line up in two lines and take your order and proceed through the emergency exit without rushing."

[0059] Group B is a group that is close to Group A. For this reason, the notification unit 18 notifies Group B with a voice message such as "Keep walking at the same speed and evacuate following the evacuees in front of you."

[0060] Group C is a group far from the emergency exit. For this reason, the notification unit 18 notifies Group C with a voice message such as, "You're almost at the emergency exit. Please increase your walking speed a little and keep walking straight. You will see a group of evacuees heading for the emergency exit ahead."

[0061] A case will be described in which the notification unit 18 is a display unit. The notification control unit 28 outputs, for example, a video showing evacuation guidance information.

[0062] A case will be described in which the notification unit 18 is a speaker. The notification control unit 28 outputs, for example, a sound indicating evacuation guidance information.

[0063] The communication control unit 29 controls communication with the mobile terminal via the communication unit 19 .

[0064] <Processing in the evacuation assistance control device> Next, information processing in the evacuation support system 1 will be described with reference to Fig. 4. Fig. 4 is a flowchart showing the flow of processing in the evacuation support control device according to the embodiment.

[0065] The evacuation support control device 20 acquires disaster information (step S101). More specifically, the evacuation support control device 20 acquires disaster information about a disaster that has occurred within a facility via the disaster information acquisition unit 21. The evacuation support control device 20 proceeds to step S102.

[0066] The evacuation support control device 20 collects position information of multiple evacuees (step S102). More specifically, the evacuation support control device 20 collects position information indicating the positions of multiple evacuees within the facility using the position information collection unit 22. The evacuation support control device 20 proceeds to step S103.

[0067] The evacuation support control device 20 analyzes the movement status of the multiple evacuees (step S103). More specifically, the movement status analysis unit 24 of the evacuation support control device 20 estimates the movement status of the multiple evacuees based on at least one of the positions, movement speeds, movement directions, and distances between the evacuees, based on the location information collected by the location information collection unit 22, and divides the multiple evacuees into groups. The evacuation support control device 20 proceeds to step S104.

[0068] The evacuation support control device 20 generates evacuation guidance information (step S104). More specifically, the evacuation support control device 20 generates, by the evacuation guidance information generation unit 25, evacuation guidance information that guides evacuation routes to exits or emergency exits within the facility for each group, based on the disaster information acquired by the disaster information acquisition unit 21 and the facility information acquired by the facility information acquisition unit 23. The evacuation support control device 20 proceeds to step S105.

[0069] The evacuation support control device 20 notifies each group of evacuation guidance information (step S105). More specifically, the evacuation support control device 20 controls the notification control unit 28 to output the evacuation guidance information to the notification unit 18. For example, the evacuation support control device 20 notifies a group close to an emergency exit to quickly reach the emergency exit and evacuate smoothly without congestion near the emergency exit through the notification control unit 28. For example, the evacuation support control device 20 notifies a group that is far from an emergency exit and is close to other groups ahead of it to follow the other groups ahead of it through the notification control unit 28. For example, the evacuation support control device 20 notifies a group that is far from an emergency exit and is far from other groups ahead of it to roughly inform them of the evacuation direction so that they can evacuate without panicking through the notification control unit 28.

[0070] <Effects> As described above, according to this embodiment, in the event of a disaster, multiple evacuees can be divided into groups based on their movement status, and evacuation guidance information for guiding each group along an evacuation route can be notified. According to this embodiment, multiple people within a facility can be efficiently guided to evacuate. According to this embodiment, multiple evacuees within a facility can be efficiently evacuated outside the facility, thereby reducing the number of evacuees remaining within the facility. In this way, this embodiment can support smooth evacuation in the event of a disaster.

[0071] In this embodiment, multiple evacuees are grouped together if their locations are within a predetermined range, their movement speeds are within a predetermined range, their movement directions are the same, or the distance between the evacuees is equal to or less than a predetermined distance. This embodiment allows for appropriate grouping to ensure efficient evacuation guidance.

[0072] In this embodiment, the notification mode can be changed for each group, and the notification can be made in a mode appropriate for each group depending on the movement status of the group, etc.

[0073] In this embodiment, the notification mode can be changed depending on the position of the evacuee within the group. According to this embodiment, the notification can be made in an appropriate notification mode depending on the position of the evacuee. According to this embodiment, more appropriate evacuation guidance can be provided.

[0074] The components of the illustrated evacuation support system are conceptual functional components and do not necessarily have to be physically configured as shown in the figure. In other words, the specific form of each device is not limited to that shown in the figure, and all or part of the devices may be functionally or physically distributed or integrated in any unit depending on the processing load and usage status of each device.

[0075] The configuration of the evacuation assistance system is realized, for example, as software, by a program loaded into memory. In the above embodiment, the system has been described as a functional block realized by the cooperation of these hardware and software. In other words, these functional blocks can be realized in various forms, using only hardware, only software, or a combination of both.

[0076] The components described above include those that can be easily imagined by a person skilled in the art and those that are substantially the same. Furthermore, the configurations described above can be combined as appropriate. Furthermore, various omissions, substitutions, or modifications of the configurations are possible within the scope of the gist of the present invention.

[0077] In the above, a guide for evacuation guidance may be preset from among the employees and staff of the facility. The notification control unit 28 may issue a voice to the guide from the notification unit 18 to guide the group, in the same way as it does for the evacuee at the front of the group. This can support smooth evacuation in the event of a disaster. [Explanation of symbols]
