Mode for Carrying Out the Invention

[0012] Hereinafter, an embodiment of the present invention will be described. In this embodiment, a building having multiple floors as a facility will be described as an example. Hereinafter, as an example of the evacuation support system of the present invention, an in-building evacuation support system will be exemplified. FIG. 1 is an overall configuration diagram of the in-building evacuation support system in this embodiment.

[0013] As shown in FIG. 1, the in-building evacuation system is composed of an information registration unit 1, a current situation identification unit 2, an evacuation information calculation unit 3, and an information output unit 4. First, the information registration unit 1 has a disaster response information registration function 11, an on-site person information registration function 12, and a facility information registration function 13. In addition, the current situation identification unit 2 has a disaster situation identification function 21, an on-site person situation identification function 22, and a facility situation identification function 23. In addition, the evacuation information calculation unit 3 has a disaster level calculation function 31, a necessary support calculation function 32 for calculating the necessary support for disabled persons etc., an evacuation route calculation function 33, and a transmitted information calculation function 34. These functions will be described later. It is desirable that the in-building evacuation system has a storage unit for storing various information described later.

[0014] Then, the information output unit 4 receives the transmitted information, which is the content calculated by the evacuation information calculation unit 3, and outputs it. In addition, the information output unit 4 can be realized by various terminals such as an evacuee terminal 41, a rescuer terminal 42, and an in-building transmission terminal 43. These information output units 4 can be realized by various devices such as mobile phones, smartphones, and display monitors. As described above, the information output unit 4 provides the transmitted information to evacuation-related persons such as on-site persons, rescue supporters, and persons in need of support, regardless of the output format such as voice, text, and image. Therefore, the information output unit 4 can also be expressed as an information providing terminal. Note that the evacuation-related persons may include those other than on-site persons such as firefighters.

[0015] Here, the information registration unit 1, the current situation identification unit 2, and the evacuation information calculation unit 3 will constitute the evacuation support device 100 in the present embodiment. This can be realized by a computer such as a server. Hereinafter, the hardware configuration when the evacuation support device 100 is realized by a computer will be described.

[0016] FIG. 14 is a system configuration diagram including the hardware configuration of the evacuation support device 100 in the present embodiment. As shown in FIG. 14, the evacuation support device 100 is connected to the evacuee terminal 41, the rescuer terminal 42, and the in-building transmission terminal 43, which are information output units 4, via the network 80. Further, the evacuation support device 100 is also connected to the IC card 51, the IC card reader 52, the fire detector 61, the camera 62, the laser sensor 63, the elevator 70, and the weather information providing system 90 used by the people in the building via the network 80.

[0017] Here, the IC card 51 and the IC card reader 52 are used by the people in the building and are used to register the in-building person information 109. For this reason, the IC card reader 52 is installed at the entrances and exits of the building and each room. That is, the IC card reader 52 reads information about the people in the building from the IC card 51 when the people in the building enter and exit. Note that the IC card 51 and the IC card reader 52 are examples of an in-building person information registration device for registering the in-building person information 109, and other terminal devices that accept login or the evacuee terminal 41 may be used to register the in-building person information 109.

[0018] Further, the fire detector 61 is provided in the building and detects the occurrence of a fire. Although one fire detector 61 is shown in the figure, it is desirable to provide a plurality of them. Further, the fire detector 61 is an example of a disaster state detection device that detects the disaster state, and other devices such as a seismometer, a water level gauge that detects tsunamis and floods, a thermal camera, and a camera may be used. Note that the disaster in the present embodiment is a broad concept including secondary disasters.

[0019] In addition, the camera 62 detects the status of the people present in the building. This status can be used to determine their position and posture. Furthermore, the camera 62 is an example of a device for detecting the status of people present, and a GPS function of the evacuee terminal 41, a wireless communication access point, a beacon, etc. may also be used.

[0020] Also, the laser sensor 63 detects the status of various facilities installed in the building. This status includes their position and operating status. In particular, the operating status includes the availability for evacuation. Note that the laser sensor 63 is an example of a device for detecting the status of facilities, and an infrared sensor, an ultrasonic sensor, etc. may also be used.

[0021] Also, the elevator 70 is an example of a facility and can also be used for evacuation. Note that facilities include escalators, emergency exits, wheelchairs, etc. In addition, the network 80 connects various devices. Note that the network 80 may be composed of a local network within the building and a wide-area network such as the Internet. For this reason, the evacuation support device 100 may be installed within the building or may be installed so as to be shared among a plurality of buildings.

[0022] Also, the weather information providing system 90 is operated by the Japan Meteorological Agency, meteorological societies, weather information providing companies, etc., and provides wide-area disaster information such as earthquakes and floods.

[0023] Here, the evacuation support device 100 will be described. The evacuation support device 100 is realized by a computer such as a server. For this reason, the evacuation support device 100 has a communication device 101, a processing device 102, a memory 103, and a storage device 104, and these are connected to each other via a communication path such as a bus. Hereinafter, each of these components will be described.

[0024] First, the communication device 101 connects to the network 80 and communicates with other devices. In addition, the processing device 102 can be realized by a processor such as a CPU (Central Processing Unit), and executes operations according to an information registration program 105, a current situation identification program 106, and an evacuation information calculation program 107 stored in a storage device 104 described later. These programs will be described later.

[0025] Also, in the memory 103, the information registration program 105, the current situation identification program 106, the evacuation information calculation program 107, and various information used in the operations by these programs are expanded. The storage device 104 can be realized by a so-called storage, and stores, in addition to the above-mentioned programs, disaster response information 108, in-house personnel information 109, facility information 110, and map information 111. The storage device 104 can be realized by various storage media such as an external HDD (Hard Disk Drive), SSD (Solid State Drive), and memory card. Furthermore, it may be realized as a device separate from the evacuation support device 100, such as a file server.

[0026] Here, the information registration program 105 realizes the functions of the information registration unit 1 shown in FIG. 1. Therefore, the information registration program 105 can be composed of modules for realizing a disaster response information registration function 11, an in-house personnel information registration function 12, and a facility information registration function 13.

[0027] Also, the current situation identification program 106 realizes operations related to the functions of the current situation identification unit 2 shown in FIG. 1. Therefore, the current situation identification program 106 can be composed of modules for realizing a disaster situation identification function 21, an in-house personnel situation identification function 22, and a facility situation identification function 23.

[0028] Also, the evacuation information calculation program 107 realizes the functions of the evacuation information calculation unit 3 shown in FIG. 1. Therefore, the evacuation information calculation program 107 can be composed of modules for realizing a disaster level calculation function 31, a required support calculation function 32, an evacuation route calculation function 33, and a transmission information calculation function 34.

[0029] Therefore, the processing device 102 will execute the operations (processing) of the information registration unit 1, the current situation identification unit 2, and the evacuation information calculation unit 3 according to each program. Note that the disaster response information 108, the information of the people in the building 109, the facility information 110, and the map information 111 will be described later.

[0030] The description of the configuration of the present embodiment ends here. Next, the processing content of the evacuation support device 100 in the present embodiment will be described.

[0031] First, briefly, the processing of the information registration unit 1 and the current situation identification unit 2 will be described. The information registration unit 1 appropriately registers various acquired information in the storage device 104 in FIG. 14. That is, the disaster response information 108 indicating the response to possible disasters, the information of the people in the building 109 of the corresponding building, and the facility information 110 about the facilities of the building are registered.

[0032] The disaster response information 108 is information indicating the response to disasters and is registered by the disaster response information registration function 11 according to the operations on the terminal devices of the administrator or the like. Also, the information of the people in the building 109 is acquired by the camera 62, the IC card reader 52, etc. when the people in the building enter the building, and is registered by the information of the people in the building registration function 12. However, the information of the people in the building registration function 12 may register the information of the people in the building 109 about the people who may be in the building in advance and activate this information when it is acquired. Also, the facility information 110 is appropriately acquired by the laser sensor 63, etc. and is registered by the facility information registration function 13. In this way, the disaster response information 108, the information of the people in the building 109, and the facility information 110 acquired by various devices and devices are registered by the information registration unit 1.

[0033] In addition, in response to a request from the evacuation information calculation unit 3, the current situation identification unit 2 reads out the registered disaster response information 108, the in-building person information 109, and the facility information 110. Further, the current situation identification unit 2 may execute the reading when the occurrence of a disaster is detected. In this way, the current situation identification unit 2 will identify the disaster situation, the in-building person situation, and the facility situation when the reading is executed. Then, the evacuation information calculation unit 3 uses these to execute an evacuation information calculation process for calculating evacuation information.

[0034] Here, before the description of the evacuation information calculation process, the disaster response information 108, the in-building person information 109, and the facility information 110 read out by the current situation identification unit 2 will be described.

[0035] FIG. 10A is a diagram showing the disaster response information 108 used in this embodiment. This disaster response information 108 is information indicating the disaster potential (risk), which is a disaster that may occur in the building, and the corresponding matters thereto. Specifically, the disaster response information 108 has items of building ID, building use, number of floors, location, disaster potential, disaster source, risk assessment, and corresponding matters.

[0036] The building ID identifies the building. The building use indicates the use of the corresponding building. The number of floors indicates the floors where the disaster potential may occur. The location identifies the location on the floors where the disaster potential may occur. The disaster potential indicates the disaster potential, that is, the cause of the disaster. The disaster source indicates the source of the disaster potential. The risk value indicates the degree of risk calculated from the occurrence possibility of the disaster potential and the urgency when it occurs. The corresponding matters indicate how to respond to the disaster potential.

[0037] For example, in Fig. 10A, on the first floor inside a 13-story office building, at the location marked "1-A" on the disaster potential map, there is a high-voltage power source, indicating a high-voltage disaster potential. Since people usually do not go to that location, the risk of human casualties is low, so the risk is evaluated as E. For this disaster potential, in addition to display and insulation measures, when a fire breaks out in the building, it is necessary to use a fire extinguishing method that can handle electrical fires in that area.

[0038] Also, in Fig. 10A, inside a two-story factory, at the location of "1-B" on the first floor, a nitrogen gas cylinder is installed. Usually, in addition to display and oxygen deficiency countermeasures, when a fire occurs in the factory, it is shown that there is a risk of container rupture due to the increase in the internal pressure of the nitrogen gas cylinder. As a result, it can be seen that it is necessary to spray the fire extinguishing agent from the upwind side and extinguish the fire around while cooling the container.

[0039] Next, the visitor information 109 will be described. Fig. 10B is a diagram showing the visitor information 109 used in this embodiment. The visitor information 109 is information regarding the assistance required by the visitors in the target building. Note that in this embodiment, customers who visit the building are used as visitors, but it is not limited to this. Therefore, the visitor information 109 has items such as customer ID, name, age, attribute, disability type, required facilities, external link, and current location. The customer ID identifies the customer. The name and age indicate the name and age of the customer respectively. The attribute is an item indicating whether the customer is a person in need of assistance. In this embodiment, it indicates whether the customer is a disabled person or a healthy person. The disability type indicates the specific type of the customer's disability. The required facilities indicate the facilities required for the customer who is in need of assistance, for example, for a disabled person. Also, the external link indicates the link destination of an external information source. Here, the external link refers to an external information source regarding the assistance required by the customer and can be realized by a disabled person service ID (portal), etc. Also, the current location indicates the location of the corresponding visitor. This is appropriately acquired by a visitor status detection device.

[0040] In the example of FIG. 10B, it is shown that Hanako in Tokyo with a customer ID of "0124" is a 62-year-old disabled person who has difficulty moving and thus needs to use a wheelchair. Also in FIG. 10B, it is shown that as an external information source, it is in information cooperation with disabled services.

[0041] Next, the facility information 110 will be described. FIG. 10C is a diagram showing the facility information 110 used in this embodiment. The facility information 110 is information regarding the facilities provided in the building.

[0042] Specifically, as shown in FIG. 10C, it has items such as building ID, building use, number of floors, number of stairways, number of escalators, number of elevators, number of emergency elevators, and number of primary evacuation shelters. Here, the building ID identifies the building. The building use indicates the use of the corresponding building. The number of building floors indicates the number of floors of the corresponding building. The number of stairways, number of escalators, number of elevators, and number of emergency elevators respectively indicate the number of stairways / escalators / elevators / emergency elevators per floor. The primary evacuation shelter indicates the number and location of the primary evacuation shelters in the corresponding building.

[0043] In the facility information 110, for example, the hotel with a building ID of "1003" is a 12-story building. And there are 6 stairways, 2 escalators, 4 elevators, and 2 emergency elevators installed per floor. Furthermore, a total of 3 primary evacuation shelters are installed on the 1st floor, 6th floor, and rooftop.

[0044] Above, the description of the disaster response information 108, the in-house person information 109, and the facility information 110 has been completed. Next, the evacuation information calculation process in the evacuation information calculation unit 3 will be described according to the flowchart shown in FIG. 2. Here, in the present embodiment, there are cases where it is impossible to visually judge a person in need of support such as a disabled person and it is impossible to give priority guidance. The following processing in the flowchart can solve this problem. First, the evacuation information calculation unit 3 acquires the disaster status, the in-house person status, and the facility status from the current situation identification unit 2 (step S301). This may be executed periodically, or the order with step S302 described later may be changed, and step S301 may be executed when a disaster is detected.

[0045] Also, the evacuation information calculation unit 3 determines whether a disaster has been detected. (Step S302). As a result, if a disaster is detected (Yes), the process proceeds to step S311. If not detected (No), the process ends.

[0046] Also, the evacuation information calculation unit 3 determines the degree of the disaster (step S311). That is, the disaster degree calculation function 31 is executed. Here, as the degree of the disaster, the seismic intensity, the degree of fire, the location (number) of the occurrence, etc. can be used.

[0047] Also, the evacuation information calculation unit 3 determines whether evacuation is necessary due to the detected disaster by the necessary support calculation function 32 (step S312). For this purpose, the evacuation information calculation unit 3 uses the degree of the disaster and the in-house person information 109. For example, the evacuation information calculation unit 3 determines that evacuation is necessary when the number of persons in need of support is a certain number or more and the degree of the disaster such as the seismic intensity or the number of locations where a fire is detected is equal to or greater than a preset threshold value. Also, the evacuation information calculation unit 3 may make a determination by comparing the degree of the disaster and the disaster status. For example, for each risk assessment, the degree of the disaster (seismic intensity or location of the fire) may be compared, and if a predetermined condition is satisfied, it may be determined that evacuation is necessary. Note that in step S312, the evacuation information calculation unit 3 may determine whether to contact relevant organizations according to the degree of the disaster. As a result, if it is determined that evacuation is necessary (Yes), the process proceeds to step S32. If it is determined that evacuation is not necessary (No), the process ends.

[0048] Further, the necessary support calculation function 32 of the evacuation information calculation unit 3 calculates the support necessary for evacuation based on the personal attributes of the people in the facility (step S32). Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates an appropriate evacuation route based on the positions and personal attributes of the people in the facility (step S33).

[0049] Also, the transmission information calculation function 34 of the evacuation information calculation unit 3 calculates transmission information based on the degree of the disaster, the necessary support, and the evacuation route (step S34). Here, the evacuation information calculation unit 3 uses the disaster information indicating the state of the disaster specified by the disaster state specification function 21 of the current situation specification unit 2 and the disaster response information 108. That is, the transmission information calculation function 34 calculates, as the transmission information, the corresponding items in the disaster response information 108 that correspond to the disaster information.

[0050] At this time, it is desirable for the transmission information calculation function 34 of the evacuation information calculation unit 3 to calculate the notification time, which is the timing for notifying the transmission information. Also, the evacuation information calculation unit 3 transmits the calculated transmission information notification time to the information output unit 4 (step S4). At this time, it is desirable for the evacuation information calculation unit 3 to also transmit the notification time. As a result, the information output unit 4 outputs, that is, provides, the notified transmission information. Also, when the notification time is transmitted, the information output unit 4 outputs the transmission information at the transmitted notification time. Therefore, the people in the facility can evacuate appropriately. Thus, the evacuation information calculation unit 3 can also be expressed as an information transmission unit for transmitting the transmission information.

[0051] Then, the evacuation information calculation unit 3 determines whether the evacuation has been completed (step S5). This is determined using the completion report from the rescuer terminal 42. Alternatively, the evacuation information calculation unit 3 may make the determination using the status of the people in the building. As a result, until the evacuation is completed (No), the processing from step S301 to S5 is repeated. When the evacuation is completed (Yes), the process ends. In the present embodiment, the transmission information is calculated by the evacuation information calculation unit 3, that is, the evacuation support device 100, but it may be calculated by other devices. For example, it may be created by an external device connected to the network 80 such as the weather information providing system 90 in FIG. 14. In this case, the evacuation support device 100 may store the transmission information created by the external device and transmit it to the information output unit 4 in step S4.

[0052] Here, the details of step S33 (evacuation route calculation process) in the evacuation information calculation process shown in FIG. 2 will be described. FIG. 3 is a flowchart showing the evacuation route calculation process in the present embodiment. It is desirable that the evacuation information calculation process and the evacuation route calculation process be executed a plurality of times periodically. That is, since the disaster changes over time, it is desirable that appropriate evacuation information calculation processes and evacuation route calculation processes be executed accordingly.

[0053] Steps S301, S302, and steps S311 - S32 are the same processes as those in FIG. 2. Then, the evacuation route calculation function 33 of the evacuation information calculation unit 3 determines whether each person in the facility is a person in need of support (step S333). For this purpose, the evacuation information calculation unit 3 uses the occupant status identified by the current situation identification unit 2. For example, the determination is made according to the "type of disability" and "required facilities". That is, when the "type of disability" is of a predetermined content or there are "required facilities", it is determined that there are persons in need of support. Further, in this step, the determination may be executed according to the comparison result between the degree of the disaster and the "type of disability" and "required facilities". For example, when the seismic intensity is 2 or more and there are "required facilities", it may be determined that there are persons in need of support. Or, when the seismic intensity is 4 or more, in addition to having "required facilities", the condition that the "type of disability" is "low moving speed" may also be set. As a result, if there are persons in need of support (Yes), the process proceeds to step S3331. If there are no persons in need of support (No), the process proceeds to step S3332. Note that hereinafter, the evacuation route for each occupant will be calculated.

[0054] Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 acquires the necessary support content for the persons in need of support calculated by the necessary support calculation function 32 (step S3331). Then, the evacuation route calculation function 33 of the evacuation information calculation unit 3 creates disaster response information 108, that is, the transmission information, in an appropriate manner, and notifies this to the information output unit 4 of the corresponding person in need of support (step S3341). In this way, by making the notification as appropriate, the priority guidance for the persons in need of support will be executed. Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates an evacuation route where the necessary support and facilities can be used (step S3351). More specifically, the evacuation route is calculated by the evacuation route calculation function 33 based on the occurrence location of the identified disaster, the location included in the status of the person in need of support, and the map information 111. Note that the evacuation route of the occupants who are not persons in need of support is also calculated based on the occurrence location of the disaster, that location, and the map information 111. Also, it is desirable to use a facility map as the map information 111.

[0055] Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 determines whether there is a person in need of support around the occupants who are not in need of support (step S3332). For this purpose, the current position in the occupant information 109 is used. For example, if the corresponding occupant and the person in need of support are in the same position or adjacent positions, it is determined that there is a person in need of care around them. As a result, if there is no person in need of care (No), the process proceeds to step S3351. Also, if there is a person in need of care (Yes), the process proceeds to step S3342 or step S3352.

[0056] Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates an evacuation route that can be used by the occupants who are not in need of support (step S3351). Also, when there is a person in need of support around and it is the first time (the first time after the disaster is detected) in the periodic evacuation route calculation process, step S3342 is executed. That is, the evacuation route calculation function 33 of the evacuation information calculation unit 3 notifies the information output unit 4 of the corresponding occupant of the transmitted information with a time difference from step S3341 (step S3342). Also, in the second and subsequent times of the periodic evacuation route calculation process, the evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates an evacuation route that avoids the person in need of support (step S3352).

[0057] Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates the required evacuation time from the moving speed of the occupant and the evacuation route (step S336). Here, the moving speed can be specified by the time-series change of the current position in the occupant information 109. Also, an item for the moving speed may be provided in the occupant information 109.

[0058] Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 determines whether the evacuation time is sufficient for the development of the disaster (step S337). For this purpose, it is desirable to use the current position of the in-building person information 109 and the primary evacuation location of the facility information 110. That is, it is desirable for the evacuation route calculation function 33 of the evacuation information calculation unit 3 to calculate the distance between the current position and the primary evacuation location, and if it is within a certain range, it is determined that the time is sufficient. At this time, the degree of the disaster may be considered to determine whether the time is sufficient. As a result, if the time is sufficient (Yes), the process proceeds to step S34. If it is not sufficient (No), the process proceeds to step S338.

[0059] Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 determines whether the primary evacuation location can be used (step S338). This determination is made based on whether the primary evacuation location is in the vicinity of the disaster occurrence location or the like. As a result, if the primary evacuation location cannot be used (No), the process proceeds to step S34. If the primary evacuation location can be used (Yes), the process proceeds to step S339.

[0060] Also, the evacuation route calculation function 33 of the evacuation information calculation unit 3 sets the primary evacuation location as the evacuation destination (step S339).

[0061] Then, steps S34 to S5 shown in FIG. 2 are executed. That is, until the evacuation is completed, the steps from S331 to S5 are repeated.

[0062] In the above-described form, when a disaster occurs, the disabled are preferentially guided to evacuate, and the healthy are guided to evacuate so as not to obstruct the evacuation route of the disabled either temporally or spatially. Therefore, congestion can be avoided, and the disabled can evacuate without being obstructed.

[0063] With the above, the description of the processing of this embodiment ends. Next, map information 111, which is an example of the transmission information created in this embodiment, and its creation will be described. Map information 111 is information indicating the situation inside a facility (building). This situation includes the arrangement of facilities. FIG. 4 is a diagram showing the disaster potential map included in the map information 111 in this embodiment. The disaster potential map shown in FIG. 5 is the disaster potential map of the first floor of a five-story research building. And, FIG. 4(a) shows the first floor of the building (structure) in the shape of a so-called floor map, and in addition to the locations of stairs, elevators, emergency exits, fire extinguishers, etc., the locations of various facilities such as chemical storage shelves and experimental equipment are shown. And, the disaster potential on the first floor is described. For example, in the example shown in FIG. 4, in Laboratory 101, chemicals are stored in a chemical storage shelf and a refrigerator, and in the chemical storage shelf, oxidizing liquids such as nitric acid and flammable liquids such as alcohol are stored. Therefore, special attention is required during a disaster. Also, since Laboratories 102 and 103 handle lasers, in the event of a disaster during laser operation, first turn off the power, and if the laser light is emitting, it is necessary to wear protective gear when entering the room. Also, in Laboratory 105, there is an electron microscope, which is a high-voltage device, and in the event of a disaster, the power should be turned off, and in the event of a fire, it is necessary to respond with the method of extinguishing an electrical fire. Also, in the disaster potential map shown in FIG. 4(b), the numbers of the locations where each disaster potential can occur are shown. The above disaster potential map may be created in advance by an administrator or the like.

[0064] Further, FIG. 5 is a diagram showing the facility map included in the map information 111 in the present embodiment. The facility map shows the arrangement of facilities in a facility (building). Note that the facility map may be registered in the storage device 104 by the facility information registration function 13. Here, FIG. 5(a) shows a hierarchical diagram of a three-story office building. Further, FIG. 5(b) shows a plan view of the third floor of the office building shown in FIG. 5(a). As shown in FIG. 5(a), on each floor of the office building, there are two stairways, one elevator hall with three elevators arranged side by side, and one emergency elevator. Also, fire extinguishers are located near the leftmost stairway and near the rightmost emergency elevator, and fire hydrants are installed near the central elevator. In addition, there is an AED facility for emergency use in the central part of each floor. Further, as shown in FIG. 5(b), in addition to the main office area, offices, meeting rooms, and private rooms for customer service are installed in the office building. Note that the map information 111 may be created in advance and stored in the storage device 104 in advance. Further, in the present embodiment, at least one of a disaster potential map and a facility map may be used as the map information 111.

[0065] Next, the details of state detection devices such as a disaster state detection device, an in-building person state detection device, and a facility state detection device will be described by exemplifying specific devices. FIG. 11 is a diagram for explaining a device used as the state detection device in the present embodiment. As the disaster state detection device, for example, a seismometer can be used. According to such a seismometer, it is possible to evaluate the degree of damage caused by an earthquake. Also, as the disaster state detection device, a water level gauge can be used. According to the water level gauge, it is possible to detect flooding in the building area due to a tsunami or heavy rain and evaluate the degree of damage. Also, as the disaster state detection device, a fire detector 61 can be used.

[0066] Furthermore, as the disaster state detection device, a thermal camera can be used. With a thermal camera, it is possible to detect a fire, evaluate the degree of the fire, and evaluate the danger range. In addition, as the disaster state detection device, a camera can be used. It is possible to detect earthquakes, tsunamis, landslides, fires, etc. from the images of the camera, and it can be installed at a low cost in multiple locations in the building.

[0067] Also, as the in-building person status device, a camera 62 or a thermal camera can be used. According to these, in addition to detecting the position of the in-building person, the current status of the in-building person can also be confirmed. In addition to these, by cooperating with an AI system for in-building person identification and motion identification, the accuracy of this information can be improved. Furthermore, as the in-building person status device, a mobile terminal (such as the evacuee terminal 41) used by the in-building person can be used. By such GPS signals of the mobile terminal, or the connection from the mobile terminal to the wireless communication access points in the building, and the connection from the beacon app installed on the mobile terminal to the beacon at a predetermined position in the building, the position of the in-building person can be measured. Although it is difficult to measure the current motion of the in-building person like a camera with a mobile terminal, since movement and stay can be known, it is possible to detect whether there is difficulty in evacuation.

[0068] And, as the facility status detection device, a laser sensor 63, an infrared sensor, or an ultrasonic sensor can be used. By these, it is possible to measure the position and operating status of facilities such as elevators. Also, depending on the installation location of the facility, it is possible to measure the status such as deformation or inclination of the facility. In addition to that, it is also possible to measure the position and status of the facility with the video of the camera, and it can be installed at multiple locations in the building at a low price. That is, a camera can also be used as the facility status detection device.

[0069] Next, an example of the degree of disaster and the determination of the necessary support and the necessity of evacuation according to this will be described. Here, the case where a fire breaks out in the building is taken as an example. Here, in order to give priority (priority guidance) to the evacuation of the persons in need of support, the determination of the degree of disaster for the persons in need of support and the healthy persons will also be described.

[0070] FIG. 12 is a diagram showing the degree of disaster in this embodiment and the criteria for necessary support and the necessity of evacuation according to this. FIG. 12 shows the criteria for determination when a fire breaks out in the building. Specifically, in FIG. 12, when the height of the fire is about 0.6 m, it shows that the persons in need of support need to evacuate from the floor where the fire breaks out. Also, it shows that no evacuation instruction is given to the healthy persons.

[0071] Also, when the height of the fire is about 1.2 m, it is determined that the person in need of assistance should evacuate outside the building. However, for healthy people, it is determined that they should evacuate from the floor where the fire broke out. That is, the determination in step S312 is executed as described above.

[0072] Next, the calculation of the evacuation route will be described. Here, when a fire breaks out inside the building, the evacuation route for a person with a disability using a wheelchair will be described as an example. FIG. 13 is a diagram for explaining the calculation of the evacuation route in the present embodiment. In FIG. 14, for each degree of disaster, the related places, facilities, and corresponding measures of the disaster are defined. Specifically, the degree of disaster, the floor where the fire broke out, the floor of the person with a disability, the emergency elevator, the primary evacuation shelter, and the corresponding measures are defined. And in the case of the degree of disaster A in FIG. 13, when the floor where the fire broke out is the first floor and the person with a disability is on the first floor, as the corresponding measure, it is defined that the person with a disability evacuates outside the building by themselves. This is because the person with a disability may use a wheelchair, so it is necessary to avoid using the stairs. Here, the evacuation route in this case is shown in FIG. 6A. In this case, as shown in FIG. 6A, the person in need of assistance (in a wheelchair) on the first floor (1F) will evacuate outside the building along the evacuation route indicated by the arrow.

[0073] Also, in the case of the degree of disaster B or C in FIG. 13, the floor where the fire broke out and the person with a disability are both on the third floor. In these cases as well, since a person with a disability using a wheelchair cannot use the stairs, as the corresponding measure, they will evacuate from the floor where the fire broke out using the emergency elevator. The evacuation routes in these cases are shown in FIG. 6B. As shown in FIG. 6B, the person in need of assistance (in a wheelchair) on the third floor (3F) will move to the emergency elevator along the evacuation route as indicated by the arrow and evacuate to the first floor (1F) by the emergency elevator.

[0074] In addition, in the case of the disaster level D in Fig. 13, the fire floor and the disabled person are both on the 3rd floor. However, in this example, there is no emergency elevator in the building, and the disabled person using a wheelchair cannot use the stairs. Therefore, as a countermeasure, evacuation to the primary evacuation shelter is shown. The evacuation route in this case is shown in Fig. 6C. In this case, as shown in Fig. 6C, the person requiring support (in a wheelchair) on the 1st floor (1F) will evacuate to the primary evacuation shelter along the evacuation route indicated by the arrow.

[0075] Furthermore, in the case of the disaster level E in Fig. 13, the fire floor and the disabled person are both on the 3rd floor. In this example, there is neither an emergency elevator nor a primary evacuation shelter in the building. Therefore, since the disabled person using a wheelchair cannot use the stairs, as a countermeasure, it is stipulated that the disabled person should wait for rescue at the place farthest from the fire point. The evacuation route in this case is shown in Fig. 6D. In this case, as shown in Fig. 6D, the person requiring support (in a wheelchair) on the 3rd floor (3F) will evacuate to the place farthest from the fire point (location) along the evacuation route indicated by the arrow. As described above, in this embodiment, an evacuation route for realizing evacuation using facilities is created using the facility information 110.

[0076] Regarding each of the tables in Figs. 11 to 13, they may be stored in the storage device 104, and the evacuation information calculation unit 3 may use them to execute each process.

[0077] Next, the calculation of the transmission information indicating the preferential evacuation of the person requiring support by the evacuation route calculation function 33 will be described. Here, the judgment criteria of the building shown in Fig. 12 are used. That is, a fire breaks out in the building, and the height of the fire is about 1.2 m. And when the fire in this building is 1 m or more, the disabled person needs to evacuate outside the building, and the other occupants in the building need to evacuate from the fire floor. In addition, an emergency elevator is installed in this building.

[0078] The evacuation route calculation function 33 executes a process for preferentially guiding the evacuation of the person requiring support over a healthy person by at least one of the following (1) to (3).

[0079] (1) Notification Priority: After a fire is detected at 0.5 m or more, the support-needed persons are notified of the evacuation information and guided to evacuate from the floor where the fire broke out. The healthy persons are not yet notified of the evacuation information. When a fire is detected at 1 m or more, the healthy persons are notified of the evacuation information to guide them to evacuate from the floor where the fire broke out.

[0080] That is, even when the degree of disaster is low and healthy persons do not need to evacuate, the support-needed persons may also be notified to evacuate first.

[0081] (2) Time Priority: When a fire is detected at 1 m or more, if the support-needed persons have not completed evacuation and are around, after a preset time difference (for example, 1 minute after the fire is detected at 1 m or more), the evacuation information is notified to the healthy persons.

[0082] That is, when the healthy persons evacuate and the support-needed persons are around, after the preset time difference has elapsed, the evacuation information is notified to the healthy persons.

[0083] (3) Space Priority: Even after implementing the priority evacuation guidance for the support-needed persons in (1) and (2), if there are support-needed persons around the healthy persons, the evacuation route for the healthy persons is set avoiding the support-needed persons.

[0084] That is, when the healthy persons evacuate and there are support-needed persons around, the evacuation route for the healthy persons is set avoiding the evacuation route of the support-needed persons.

[0085] As described above, the transmitted information including the evacuation route according to the degree of disaster is calculated. As a result, the priority evacuation of the support-needed persons is executed. Among these, (3) Space Priority is shown in FIG. 7. In FIG. 7, the support-needed persons who need to use a wheelchair and the healthy persons will evacuate from the office area at the same time, and the evacuation route for the support-needed persons is calculated to be the shortest preferentially. In contrast, although the healthy persons are closer to the upper exit, the evacuation route is calculated by the evacuation route calculation function 33 so that they leave the office area from the lower exit significantly and evacuate to the stairs so as not to overlap with the evacuation route of the support-needed persons.

[0086] Next, the output content (display screen) of the information output unit 4 in this embodiment will be described. Here, when the person in need of support and a healthy person are in the same area, the transmitted information for the person in need of support and the healthy person will be described as an example. FIG. 8A is a diagram showing the screen of the evacuee terminal 41 of the person in need of support that realizes the priority evacuation of the person in need of support in this embodiment. Here, the display is performed by an appropriate notification method according to the attributes of the people in the facility who are using the evacuee terminal 41. For example, for healthy people, the detection of a disaster is notified by an audio alarm or a screen as shown in FIG. 8A. On the other hand, for people with hearing impairments, instead of an audio alarm, the notification is made by the vibration of the mobile phone or a screen as shown in FIG. 8A. Also, for people with visual impairments, an audio alarm and audio evacuation guidance are provided.

[0087] Here, when a disaster occurs, it is desirable to switch to a disaster notification screen regardless of the usage status of the evacuee terminal 41, such as the Emergency Earthquake Early Warning. Also, on the disaster notification screen, the type of disaster, the degree of the disaster, the evacuation destination, and a map of the floor where the current people in the facility are located are displayed. On the map, the disaster location (when it occurs on the same floor), the current location of the people in the facility, and the evacuation route are shown.

[0088] For example, a fire breaks out on the 3rd floor of a building with an emergency elevator, and the degree of the disaster for the person in need of support is determined to be "evacuation outside the building required". As a result, the person in need of support who is using the evacuee terminal 41 is in the office area on the 3rd floor and needs to use a wheelchair. Therefore, it is necessary to take the emergency elevator down to the 1st floor and evacuate outside. So, on the notification screen, the following content is displayed in text and illustration of "Fire". The degree of the disaster of "evacuation outside the building required" and the evacuation destination of "→ outside" are displayed, and on the map of the 3rd floor of the current location, a fire breaks out near the staircase in the lower left, and the evacuation route from the current office area to the emergency elevator is shown by a blue dotted line.

[0089] Also, if the person in need of assistance has a visual impairment, they cannot confirm the evacuation route on the screen. Therefore, based on the registered in-house personnel information, the evacuation route guidance for the person in need of assistance is based on their current location, and voice guidance such as "Turn left and proceed 5 meters", "After exiting the door, turn right and proceed 2 meters", "Take the emergency elevator" is used to guide the evacuation of the person in need of assistance.

[0090] Next, the screen of the evacuation terminal 41 of a healthy evacuee around the person in need of assistance will be described with reference to FIG. 8B. For healthy people, they are notified by a voice alarm and a notification screen. And on the notification screen, the type of disaster, the degree of the disaster, the evacuation destination, and a map of the floor where the current in-house personnel are located are displayed.

[0091] Also, on the map, the disaster location (if it occurs on the same floor), the current location of the in-house personnel, positions of other people in need of assistance around, except for the evacuation route, are shown. Therefore, since the position of the person in need of assistance is known and the evacuation route avoids the person in need of assistance so as not to impede the evacuation of the person in need of assistance, healthy people are guided.

[0092] For example, a fire breaks out on the 3rd floor of a building with an emergency elevator, and the degree of the disaster for healthy people is judged to be "Evacuation required inside the building". And a healthy person using the evacuation terminal 41 is in the office area on the 3rd floor, and there are people in need of assistance around. Therefore, it is necessary to evacuate while avoiding the evacuation route of the person in need of assistance. So, on the notification screen, the characters and illustrations of "Fire", the degree of the disaster "Evacuation required inside the building", and the evacuation destination "→1F" are displayed. Also, on the notification screen, on the map of the current 3rd floor, a fire breaks out near the staircase in the lower left, and the evacuation route from the current office area to the staircase is shown by a purple dotted line. Furthermore, the people in need of assistance around are shown by blue marks. Also, since the people in need of assistance around use the upper exit of the office area, the healthy person using this evacuation terminal 41 can evacuate using the lower exit of the office area.

[0093] Finally, regarding the case of calling for rescue when the facility required by the people in the building is not available during evacuation or when it is impossible to evacuate outside due to a disaster, it will be described with reference to FIG. 9. FIG. 9 is a diagram showing the screen of the evacuee terminal 41 that is making a rescue call in this embodiment.

[0094] Here, assume that a fire breaks out and the fire has spread to near the exit where the people in the building are trying to escape, making it impossible to escape outside and move inside the building. Or assume that due to an earthquake, the wall at the end of the evacuation passage has collapsed, making it impossible to escape outside and move in the middle of the passage. Suppose the position of the evacuee terminal 41 used by the people in the building (evacuees) is detected not to have moved along the evacuation route and to have stayed within a certain range. This detection can be performed by the GPS function of the evacuee terminal 41. When detected in this way, a rescue call button pops out on the notification screen of the evacuee terminal 41. If there is no response to the rescue call button within a predetermined time of 60 seconds, the evacuee terminal 41 determines that the user may have lost consciousness or that it is difficult to manually call for rescue otherwise, and automatically makes a rescue call. If a person in the building does not want to call for rescue but accidentally makes a rescue call, or if they become able to evacuate during the rescue call, it is also possible to cancel the rescue.

[0095] With the above, the description of this embodiment ends, but the present invention is not limited to this embodiment. For example, the evacuation information calculation unit 3 may create and notify, as the transmitted information, an operation control command for an elevator or an emergency elevator according to the evacuation route. As a result, the elevator or the emergency elevator can wait for the people in the building on the corresponding floor during a disaster.
