Description

The present invention relates to technology for supporting evacuation in facilities such as buildings. In particular, it relates to evacuation support that takes into consideration people who need assistance.

When a disaster occurs, there is a device that transmits disaster information and evacuation information to wireless terminals via a network, showing evacuation routes for people to evacuate. However, evacuation capabilities, speed, and possible routes vary depending on a person's attributes. Therefore, Patent Document 1 discloses an evacuation guidance device that calculates the optimal route for an individual based on the individual's location information, attribute information, route information, and disaster information, and notifies the individual via a wireless terminal.

JP 2017-004213 A

However, in Patent Document 1, the personal attributes of evacuees, such as disabilities, are taken into consideration only when calculating evacuation routes. As a result, the specific content of support, such as appropriate disaster notification methods, differs depending on the level and type of disability of the evacuees.

In addition, when disabled and able-bodied people evacuate at the same time, there is a risk of evacuation routes becoming congested due to differences in evacuation speed and an increase in the number of evacuees. This hinders the evacuation of people with low evacuation capabilities, such as disabled people, making it difficult for them to evacuate.

The present invention was made in consideration of the above problems, and aims to realize appropriate evacuation support based on individual attributes. In particular, it guides people who need assistance, such as people with disabilities, to evacuate first.

To solve the above problem, the present invention provides priority guidance to people who require assistance, such as people with disabilities.

More specifically, in an evacuation support device for supporting the evacuation of people present in a facility in the event of a disaster, the device has a memory unit that stores information about people present including an attribute indicating whether the people present are people requiring assistance, a current situation determination unit that identifies the extent of the disaster related to the facility and determines the status of the people present, and an information transmission unit that transmits information including priority guidance to people present who require assistance and whose attribute indicates that they require assistance, to an information provision terminal provided to evacuation-related parties involved in the evacuation, the information transmission unit calculating the transmission information using the information about the people present , and an evacuation support method using this evacuation support device and an evacuation support system that includes this evacuation support device.

The present invention also includes a method using an evacuation support device or an evacuation support system, as well as a program that causes the evacuation support device to function as a computer and a storage medium that stores the program.

The present invention makes it possible to provide evacuation assistance that takes into account the personal attributes of people inside a facility.

FIG. 10 is a diagram for explaining calculation of an evacuation route in one embodiment of the present invention. 1 is a system configuration diagram including a hardware configuration of an evacuation support device according to an embodiment of the present invention.

One embodiment of the present invention will be described below. In this embodiment, a building having multiple floors will be described as an example of a facility. Below, an in-building evacuation support system will be illustrated as an example of the evacuation support system of the present invention. Figure 1 is an overall configuration diagram of the in-building evacuation support system in this embodiment.

As shown in FIG. 1, the building evacuation system is composed of an information registration unit 1, a current situation determination 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, a resident information registration function 12, and an equipment information registration function 13. The current situation determination unit 2 has a disaster state determination function 21, a resident state determination function 22, and an equipment state determination function 23. Furthermore, the evacuation information calculation unit 3 has a disaster extent calculation function 31, a necessary support calculation function 32 that calculates the support required by persons with disabilities, etc., an evacuation route calculation function 33, and a transmission information calculation function 34. Each of these functions will be explained later. It is desirable for the building evacuation system to have a memory unit that stores various information, which will be described later.

The information output unit 4 then accepts the transmission information, which is the content calculated by the evacuation information calculation unit 3, and outputs this. 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 a mobile phone, a smartphone, and a display monitor. As described above, the information output unit 4 provides transmission information to evacuation-related parties, such as those present in the building, rescue supporters, and those requiring support, regardless of the output format, such as voice, text, or image. For this reason, the information output unit 4 can also be expressed as an information provision terminal. Note that evacuation-related parties may include people other than those present in the building, such as fire department personnel.

Here, the information registration unit 1, the current situation determination unit 2, and the evacuation information calculation unit 3 constitute the evacuation support device 100 in this embodiment. This can be realized by a computer such as a server. Below, we will explain the hardware configuration when the evacuation support device 100 is realized by a computer.

Figure 14 is a system configuration diagram including the hardware configuration of the evacuation support device 100 in this embodiment. As shown in Figure 14, the evacuation support device 100 is connected to an evacuee terminal 41, a rescuer terminal 42, and an in-building transmission terminal 43, which are information output units 4, via a network 80. The evacuation support device 100 is also connected to IC cards 51 and IC card readers 52 used by people present in the building, fire detectors 61, cameras 62, laser sensors 63, elevators 70, and a weather information providing system 90 via the network 80.

The IC card 51 and IC card reader 52 are used by the people in the building to register the occupant 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 occupant from the IC card 51 when the occupant enters or leaves the building. Note that the IC card 51 and IC card reader 52 are examples of a occupant information registration device for registering the occupant information 109, and the occupant information 109 may also be registered using a terminal device that accepts logins or the evacuee terminal 41.

Furthermore, a fire detector 61 is installed in the building and detects the occurrence of a fire. Although one fire detector 61 is shown in the figure, it is desirable to install multiple fire detectors. Furthermore, the fire detector 61 is an example of a disaster state detection device that detects a disaster state, and other devices that may be used include a seismometer, a water level gauge that detects tsunamis and floods, a thermo camera, and a camera. Note that a disaster in this embodiment is a broad concept that also includes secondary disasters.

The camera 62 also detects the status of people in the building. This status can be determined by their position and posture. The camera 62 is an example of a device for detecting the status of people in the building, and the evacuee terminal 41 (GPS function), a wireless communication access point, a beacon, etc. may also be used.

The laser sensor 63 also detects the status of various pieces of equipment installed in the building. This status includes their location and operating status. In particular, the operating status includes the possibility of use during evacuation. Note that the laser sensor 63 is an example of an equipment status detection device, and an infrared sensor, ultrasonic sensor, etc. may also be used.

The elevator 70 is an example of equipment that can also be used for evacuation. Equipment includes escalators, emergency exits, wheelchairs, etc. The network 80 connects various devices. The network 80 may be composed of a local network within a building and a wide area network such as the Internet. For this reason, the evacuation support device 100 may be installed within a building, or may be installed so as to be shared by multiple buildings.

The weather information providing system 90 is operated by the Japan Meteorological Agency, the Meteorological Association, weather information providing companies, etc., and provides information on wide-area disasters such as earthquakes and floods.

Here, we will explain the evacuation support device 100. 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, which are connected to each other via a communication path such as a bus. Each of these components will be explained below.

First, the communication device 101 connects to the network 80 and communicates with other devices.
The processing device 102 can be realized by a processor such as a CPU (Central Processing Unit), and executes calculations 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, which will be described later. Each of these programs will be described later.

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

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 configured with modules for realizing the disaster response information registration function 11, the occupant information registration function 12, and the facility information registration function 13.

The current situation identification program 106 also realizes calculations for the functions of the current situation identification unit 2 shown in FIG. 1. Therefore, the current situation identification program 106 can be configured with modules for realizing the disaster state identification function 21, the occupant state identification function 22, and the equipment state identification function 23.

The evacuation information calculation program 107 also realizes the functions of the evacuation information calculation unit 3 shown in FIG. 1. Therefore, the evacuation information calculation program 107 can be configured with modules for realizing the disaster extent calculation function 31, the required support calculation function 32, the evacuation route calculation function 33, and the dispatch information calculation function 34.

The processing device 102 therefore executes the calculations (processing) of the information registration unit 1, current situation determination unit 2, and evacuation information calculation unit 3 in accordance with each program. Disaster response information 108, occupant information 109, facility information 110, and map information 111 will be described later.

This concludes the explanation of the configuration of this embodiment. Below, we will explain the processing details of the evacuation support device 100 in this embodiment.

First, the processing of the information registration unit 1 and the current situation determination unit 2 will be briefly described. The information registration unit 1 registers various pieces of information acquired as appropriate in the storage device 104 in FIG. 14. That is, disaster response information 108 indicating responses to possible disasters, information 109 on people present in the building, and equipment information 110 on the facilities of the building are registered.

Disaster response information 108 is information indicating a response to a disaster, and is registered by disaster response information registration function 11 in response to operations on a terminal device by an administrator or the like. In addition, occupant information 109 is acquired by camera 62, IC card reader 52, etc., when an inhabitant enters the building, and is registered by occupant information registration function 12. However, occupant information registration function 12 may register in advance occupant information 109 about people who may be in the building, and validate this when acquired. In addition, facility information 110 is acquired as appropriate by laser sensor 63, etc., and registered by facility information registration function 13. In this way, disaster response information 108, occupant information 109, and facility information 110 acquired by various devices are registered by information registration unit 1.

In addition, the current situation determination unit 2 reads out the registered disaster response information 108, occupant information 109, and facility information 110 in response to a request from the evacuation information calculation unit 3. The current situation determination unit 2 may also execute reading when the occurrence of a disaster is detected. In this way, the current situation determination unit 2 determines the disaster state, occupant status, and facility status at the time of executing reading. The evacuation information calculation unit 3 then uses these to execute an evacuation information calculation process that calculates evacuation information.

Before explaining the evacuation information calculation process, we will now explain the disaster response information 108, occupant information 109, and facility information 110 that are read by the current situation determination unit 2.

Figure 10A is a diagram showing disaster response information 108 used in this embodiment. This disaster response information 108 is information that indicates disaster potential (risk), which is a disaster that may occur within a building, and the measures to be taken in response to this. Specifically, the disaster response information 108 has the following items: building ID, building use, number of floors, location, disaster potential, disaster source, risk assessment, and measures to be taken.

The building ID identifies the building. The building use indicates the use of the building. The floor number indicates the floor on which the disaster potential may occur. The location identifies the location on the floor on which the disaster potential may occur. The disaster potential indicates the disaster potential, i.e., 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 possibility of the disaster potential occurring and the urgency of the disaster if it does occur. The response items indicate how to respond to the disaster potential.

For example, Figure 10A shows that there is a high-voltage power source on the first floor of a 13-story office building, in a location marked "1-A" on the disaster potential map, and that there is a high-voltage disaster potential. Since people do not normally go to that location, the possibility of human casualties is low, and so the risk is rated as E. In response to this disaster potential, in addition to signs and insulation measures, if a fire breaks out in the building, it is necessary to use fire extinguishing methods that can deal with electrical fires in that area.

Also, in Figure 10A, a nitrogen gas cylinder is installed at location "1-B" on the first floor of a two-story factory, and apart from being normally displayed and used as a measure against oxygen deficiency, it is also shown that in the event of a fire inside the factory, there is a risk of the nitrogen gas cylinder bursting due to an increase in internal pressure. As a result, it is necessary to spray a fire extinguishing agent from upwind and extinguish the surrounding area while cooling the container.

Next, the occupant information 109 will be described. FIG. 10B is a diagram showing the occupant information 109 used in this embodiment. The occupant information 109 is information about the need for support of occupants in the target building. In this embodiment, customers who visit the building are used as occupants, but this is not limited to this. For this reason, the occupant information 109 has the following items: customer ID, name, age, attribute, type of disability, necessary 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 that indicates whether the customer is in need of support, and in this embodiment indicates a disabled person or a healthy person. The type of disability indicates the specific type of disability of the customer. The necessary facilities indicate the facilities necessary for evacuation when the customer is in need of support, for example, a disabled person. In addition, the external link indicates the link destination of the external information source. Here, the external link indicates an external information source regarding the customer's need for support, and can be realized by a disability service ID (portal) or the like. Additionally, the current location indicates the location of the person in question. This is obtained as appropriate by the person status detection device.

In the example of Figure 10B, it is shown that Tokyo Hanako, whose customer ID is "0124", is a 62-year-old person with a disability who has difficulty moving around and needs to use a wheelchair. Also, Figure 10B shows that information is linked to a service for people with disabilities as an external information source.

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 about the facilities installed in the building.

Specifically, as shown in FIG. 10C, the fields include building ID, building use, number of floors, number of stairs, number of escalators, number of elevators, number of emergency elevators, and primary evacuation shelters. Here, the building ID identifies the building. The building use indicates the use of the building. The number of building floors indicates the number of floors in the building. The number of stairs, number of escalators, number of elevators, and number of emergency elevators indicate the number of stairs/escalators/elevators/emergency elevators per floor, respectively. Primary evacuation shelters indicates the number of primary evacuation shelters in the building and their locations.

In facility information 110, for example, a hotel with building ID "1003" is a 12-story building. Each floor has six stairs, two escalators, four elevators, and two emergency elevators. In addition, a total of three primary evacuation shelters are provided on the first floor, sixth floor, and rooftop.

This concludes the explanation of the disaster response information 108, occupant information 109, and facility information 110. Below, the evacuation information calculation process in the evacuation information calculation unit 3 will be explained according to the flowchart shown in FIG. 2. In this embodiment, there are cases where people requiring assistance, such as people with disabilities, cannot be identified by appearance and priority guidance is not possible. The process in the flowchart below can solve this problem. First, the evacuation information calculation unit 3 acquires the disaster status, occupant status, and facility status from the current situation identification unit 2 (step S301). This may be performed periodically, or the order of step S302 described below may be changed so that step S301 is performed when a disaster is detected.

The evacuation information calculation unit 3 also determines whether a disaster has been detected (step S302). As a result, if a disaster has been detected (Yes), the process proceeds to step S311. If a disaster has not been detected (No), the process ends.

The evacuation information calculation unit 3 also determines the extent of the disaster (step S311). That is, the disaster extent calculation function 31 is executed. Here, the extent of the disaster can be determined by seismic intensity, the extent of fires, the locations (number) of occurrences, etc.

The evacuation information calculation unit 3 also uses the support requirement calculation function 32 to determine whether evacuation is necessary due to the detected disaster (step S312). For this purpose, the evacuation information calculation unit 3 uses the degree of the disaster and the information on people present in the building 109. For example, the evacuation information calculation unit 3 determines that evacuation is necessary when there are a certain number of people requiring support or more, and the degree of the disaster, such as the seismic intensity or the number of places where fires are detected, is equal to or greater than a preset threshold. The evacuation information calculation unit 3 may also compare the degree of the disaster with the disaster state to make a determination. For example, the degree of the disaster (seismic intensity or location of the fire) may be compared for each risk assessment, and if a predetermined condition is met, it may be determined that evacuation is necessary. In step S312, the evacuation information calculation unit 3 may determine whether to contact related organizations depending on the degree of the disaster. As a result, if it is determined that evacuation is necessary (Yes), the process transitions to step S32. If it is determined that evacuation is not necessary (No), the process ends.

The necessary support calculation function 32 of the evacuation information calculation unit 3 calculates the support required for evacuation based on the personal attributes of the people in the building (step S32). 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 building (step S33).

Then, the transmission information calculation function 34 of the evacuation information calculation unit 3 calculates transmission information based on the extent 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 identified by the disaster state identification function 21 of the current situation identification unit 2, and the disaster response information 108. In other words, the transmission information calculation function 34 calculates the response items corresponding to the disaster information from the disaster response information 108 as transmission information.

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. Furthermore, 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. Furthermore, when the notification time is transmitted, the information output unit 4 will output the transmission information at the transmitted notification time. Therefore, it becomes possible for people in the building to evacuate appropriately. In this way, the evacuation information calculation unit 3 can also be described as an information transmission unit, since it issues transmission information.

Then, the evacuation information calculation unit 3 judges whether the evacuation is completed (step S5). This is judged using a completion report from the rescuer terminal 42. The evacuation information calculation unit 3 may also judge using the status of people present in the building. As a result, the processes from steps S301 to S5 are repeated until the evacuation is completed (No). If the evacuation is completed (Yes), the process ends. Note that in this 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 transmission information created by the external device may be stored in the evacuation support device 100, and in step S4, it may be configured to transmit the transmission information to the information output unit 4.

Here, the details of step S33 (evacuation route calculation process) of the evacuation information calculation process shown in FIG. 2 will be described. FIG. 3 is a flowchart showing the evacuation route calculation process in this embodiment. Note that it is desirable that the evacuation information calculation process and the evacuation route calculation process are executed periodically multiple times. In other words, since disasters change over time, it is desirable to execute appropriate evacuation information calculation process and evacuation route calculation process in response to this.

Steps S301, S302 and steps S311 to 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 of the occupants is a person requiring 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 the "necessary facilities". In other words, if the "type of disability" is a predetermined content or if there is a "necessary facility", it is determined that a person requiring support exists. Furthermore, in this step, the determination may be made according to the comparison of the degree of the disaster and the "type of disability" and the "necessary facility". For example, if there is a "necessary facility" at a seismic intensity of 2 or more, it may be determined that a person requiring support exists, and if there is a "necessary facility" at a seismic intensity of 4 or more, in addition to the existence of a "necessary facility", the "type of disability" may also be set as a condition of "low moving speed". As a result, if there is a person requiring support (Yes), the process transitions to step S3331. If there is no person requiring assistance (No), the process proceeds to step S3332. In the following, evacuation routes for each person present in the building will be calculated.

The evacuation route calculation function 33 of the evacuation information calculation unit 3 obtains the necessary support content for the person requiring 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, transmission information, in an appropriate manner and notifies the information output unit 4 of the corresponding person requiring support (step S3341). By notifying appropriately in this way, priority guidance is provided to the person requiring support. The evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates an evacuation route that allows the necessary support and facilities to be used (step S3351). More specifically, the evacuation route calculation function 33 calculates an evacuation route based on the specified disaster occurrence location, the location included in the state of the person requiring support, and the map information 111. The evacuation route for people in the building who are not people requiring support is also calculated based on the disaster occurrence location, its location, and the map information 111. It is also preferable to use a facility map as the map information 111.

The evacuation route calculation function 33 of the evacuation information calculation unit 3 also determines whether there is a person requiring support around the person who is not requiring support (step S3332). For this purpose, the current location of the person present information 109 is used. For example, if the person requiring support and the person present are in the same location or adjacent locations, it is determined that there is a person requiring care nearby. If there is no person requiring care (No) as a result, the process transitions to step S3351. If there is a person requiring care (Yes), the process transitions to step S3342 or step S3352.

The evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates an evacuation route that can be used by people in the building who do not require assistance (step S3351). If there is a person requiring assistance nearby and this is the first time the periodic evacuation route calculation process is performed (the first time since the disaster was detected), 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 relevant person in the building of the transmission information with a time difference from step S3341 (step S3342). From the second time onwards 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 people in need of assistance (step S3352).

The evacuation route calculation function 33 of the evacuation information calculation unit 3 calculates the required evacuation time from the movement speed of the occupants and the evacuation route (step S336). Here, the movement speed can be identified from the time series change of the current location of the occupants information 109. Also, a movement speed item may be added to the occupants information 109.

The evacuation route calculation function 33 of the evacuation information calculation unit 3 also determines whether the evacuation time is sufficient to prevent the disaster from progressing (step S337). For this purpose, it is desirable to use the current location from the occupant information 109 and the primary evacuation site from the facility information 110. In other words, it is desirable to calculate the distance between the current location and the primary evacuation site using the evacuation route calculation function 33 of the evacuation information calculation unit 3, and determine that the time is sufficient if it is within a certain range. At this time, the extent of the disaster may be taken into consideration when determining whether the time is sufficient. As a result, if the time is sufficient (Yes), the process transitions to step S34. If the time is not sufficient (No), the process transitions to step S338.

The evacuation route calculation function 33 of the evacuation information calculation unit 3 determines whether the primary evacuation shelter can be used (step S338). This determination is made based on whether the primary evacuation shelter is close to the location where the disaster occurred, etc. As a result, if the primary evacuation shelter cannot be used (No), the process transitions to step S34. If the primary evacuation shelter can be used (Yes), the process transitions to step S339.

In addition, the evacuation route calculation function 33 of the evacuation information calculation unit 3 sets the primary evacuation shelter as the evacuation destination (step S339).

Then, steps S34 to S5 shown in Figure 2 are executed. In other words, steps S331 to S5 are repeated until evacuation is completed.

In the above-mentioned system, when a disaster occurs, disabled people are given priority in evacuating, and able-bodied people are guided to evacuate in a way that does not obstruct the evacuation route of disabled people in terms of time or space, thus avoiding congestion and allowing disabled people to evacuate without obstructing them.

This concludes the description of the processing of this embodiment. Next, the map information 111, which is an example of the transmission information created in this embodiment, and its creation will be described. The map information 111 is information showing the situation inside the facility (building). This situation includes the arrangement of the equipment. FIG. 4 is a diagram showing a disaster potential map included in the map information 111 in this embodiment. The disaster potential map shown in FIG. 5 shows a disaster potential map of the first floor of a five-story building used for research. FIG. 4(a) shows the first floor of a building in the form of a so-called floor map, and shows the locations of various facilities such as chemical storage shelves and experimental equipment in addition to the locations of stairs, elevators, emergency exits, and fire extinguishers. The disaster potential on the first floor is then described. For example, in the example shown in FIG. 4, chemicals are stored in the chemical storage shelves and refrigerators in the laboratory 101, and oxidizing liquids such as nitric acid and flammable liquids such as alcohol are stored in the chemical storage shelves. For this reason, special care must be taken in the event of a disaster. In addition, since lasers are used in laboratories 102 and 103, if a disaster occurs during laser work, the power must be turned off, and if laser light is being emitted, protective equipment must be worn to enter the room. In addition, laboratory 105 contains an electron microscope, which is a high-voltage device, and if a disaster occurs, the power must be turned off, and if a fire occurs, it must be dealt with using methods for extinguishing electrical fires. The disaster potential map shown in FIG. 4(b) indicates the numbers of locations where each disaster potential can occur. The above disaster potential map may be created in advance by a manager, etc.

Figure 5 is a diagram showing an equipment map included in the map information 111 in this embodiment. The equipment map shows the layout of the equipment in the facility (building). The equipment map may be registered in the storage device 104 by the equipment information registration function 13. Here, Figure 5 (a) shows a hierarchical diagram of a three-story office building. Figure 5 (b) shows a plan view of the third floor of the office building shown in Figure 5 (a). As shown in Figure 5 (a), each floor of the office building has two staircases, three elevators lined up in one location, and one emergency elevator. In addition, fire extinguishers are located near the stairs on the left end and near the emergency elevator on the right end, and a fire hydrant is installed near the elevator in the center. In addition, there is an AED facility for emergency use in the center of each floor. As shown in Figure 5 (b), in addition to the main office area, the office building has an office room, a conference room, and a private room for customer service. The map information 111 may be created in advance and stored in the storage device 104 in advance. Furthermore, in this embodiment, at least one of a disaster potential map and a facility map may be used as the map information 111.

Next, details of the status detection devices, such as the disaster status detection device, occupant status detection device, and equipment status detection device, will be explained using specific device examples. FIG. 11 is a diagram for explaining devices used as status detection devices in this embodiment. For example, a seismic intensity meter can be used as the disaster status detection device. Such a seismometer makes it possible to evaluate the extent of earthquake damage. A water level meter can also be used as the disaster status detection device. The water level meter makes it possible to detect flooding in building areas due to tsunamis or heavy rain and evaluate the extent of the damage. A fire detector 61 can also be used as the disaster status detection device.

Furthermore, a thermal camera can also be used as a disaster condition detection device. A thermal camera can detect fires and assess the extent of the fire and the danger area. In addition, a camera can also be used as a disaster condition detection device. Earthquakes, tsunamis, landslides, fires, etc. can be detected using camera footage, and the camera can be installed in multiple locations within a building at a low cost.

In addition, a camera 62 or a thermal camera can be used as the occupant status device. These can detect the location of occupants and also check their current status. In addition, by linking with an AI system for identifying occupants and their behavior, the accuracy of this information can be improved. Furthermore, a mobile terminal used by occupants (such as the evacuee terminal 41) can be used as the occupant status device. The location of occupants can be measured using GPS signals from such a mobile terminal, or by connecting the mobile terminal to a wireless communication access point within the building, or by connecting a beacon at a specified location within the building from a beacon app installed on the mobile terminal. It is difficult to measure the current behavior of occupants with a mobile terminal like a camera, but since it can determine their movement and stay, it is possible to detect whether there are any difficulties in evacuation.

Laser sensors 63, infrared sensors, and ultrasonic sensors can be used as equipment status detection devices. These can be used to measure the position and operating status of equipment such as elevators. Depending on where the equipment is installed, it can also be possible to measure the equipment's condition, such as deformation or tilt. In addition, it is possible to measure the equipment's position and condition using camera images, and these can be installed in multiple locations within a building at low cost. In other words, cameras can also be used as equipment status detection devices.

Next, we will explain an example of the level of a disaster and the corresponding determination of the need for necessary assistance and evacuation. Here, we will take the example of a fire breaking out in a building. In order to give priority (priority guidance) to the evacuation of those who need assistance, we will also explain how to determine the level of disaster for those who need assistance and those without.

Figure 12 is a diagram showing the level of disaster in this embodiment, the corresponding support required, and the criteria for determining whether or not evacuation is necessary. Figure 12 shows the criteria for determining when a fire breaks out in a building. Specifically, Figure 12 shows that when the height of the fire is about 0.6 m, people requiring assistance need to evacuate from the floor where the fire started. It also shows that evacuation orders will not be issued to able-bodied people.

In addition, if the height of the fire is about 1.2 m, it is determined that those requiring assistance should evacuate to the outside of the building, but able-bodied people should evacuate from the floor where the fire started. In other words, the determination in step S312 is executed as described above.

Next, the calculation of evacuation routes will be explained. Here, an evacuation route for a disabled person using a wheelchair in the event of a fire in a building will be explained as an example. FIG. 13 is a diagram for explaining the calculation of evacuation routes in this embodiment. In FIG. 14, disaster-related locations and facilities and their corresponding matters are specified for each level of disaster. Specifically, the level of disaster, the floor where the fire started, the floor for disabled people, the emergency elevator, the primary evacuation shelter, and the corresponding matters are specified. In addition, in the level of disaster A in FIG. 13, if the floor where the fire started is the first floor and a disabled person is on the first floor, it is specified as a corresponding matter that the disabled person evacuates outside the building by himself. This is because a disabled person may use a wheelchair, so it is necessary to avoid using stairs. Here, the evacuation route in this case is shown in FIG. 6A. In this case, as shown in FIG. 6A, a person requiring assistance (wheelchair) on the first floor (1F) will evacuate to the outside of the building via the evacuation route indicated by the arrow.

In addition, in disaster levels B and C in Figure 13, the floor where the fire started and the disabled person are both on the third floor. In these cases, disabled people who use wheelchairs cannot use the stairs, so the appropriate measure is to evacuate from the floor where the fire started using the emergency elevator. Evacuation routes in these cases are shown in Figure 6B. As shown in Figure 6B, a person requiring assistance (wheelchair) on the third floor (3F) will move to the emergency elevator via the evacuation route, as shown by the arrow, and evacuate to the first floor (1F) using the emergency elevator.

In addition, in the disaster level D in Figure 13, the floor where the fire started and the disabled person are both on the third floor. However, in this example, there are no emergency elevators in the building, and disabled people who use wheelchairs cannot use the stairs, so evacuation to a primary evacuation shelter is indicated as a response. The evacuation route in this case is shown in Figure 6C. In this case, as shown in Figure 6C, the person requiring assistance (in a wheelchair) on the first floor (1F) will evacuate to the primary evacuation shelter via the evacuation route indicated by the arrow.

Furthermore, in disaster level E in FIG. 13, the floor where the fire started and the disabled person are both on the third floor. In this example, there are no emergency elevators or primary evacuation shelters in the building. For this reason, disabled people who use wheelchairs cannot use the stairs, so the response is stipulated to wait for rescue at the location farthest from the point of fire. The evacuation route in this case is shown in FIG. 6D. In this case, as shown in FIG. 6D, the person requiring assistance (wheelchair) on the third floor (3F) will evacuate to the location farthest from the point of fire (location) via the evacuation route indicated by the arrow. As described above, in this embodiment, an evacuation route that realizes evacuation using equipment is created using equipment information 110.

Note that each table in Figures 11 to 13 may be stored in the storage device 104, and the evacuation information calculation unit 3 may use this to execute each process.

Next, we will explain how the evacuation route calculation function 33 calculates the information to be transmitted, indicating the priority evacuation of people requiring assistance. Here, we use the building judgment criteria shown in Figure 12. That is, a fire breaks out in a building, and the height of the fire is approximately 1.2 m. If the fire in this building reaches a height of 1 m or more, people with disabilities must evacuate outside the building, and other people in the building must evacuate from the floor where the fire started. In addition, the building is equipped with an emergency elevator.

The evacuation route calculation function 33 performs processing to guide people requiring assistance to evacuate in preference to able-bodied people using at least one of the following (1) to (3).

(1) Notification priority: After a fire is detected to be 0.5 m or higher, those requiring assistance will be notified of evacuation information and guided to evacuate from the floor where the fire started. Able-bodied people will not be notified of evacuation information yet. When a fire is detected to be 1 m or higher, able-bodied people will be notified of evacuation information and guided to evacuate from the floor where the fire started.

In other words, even if the level of the disaster is low and able-bodied people do not need to evacuate, people who require assistance may be notified to evacuate first.

(2) Time priority: When a fire is detected to be 1m or higher, if a person requiring assistance has not completed evacuation and is still nearby, evacuation information will be sent to able-bodied individuals after a pre-set time lag (for example, 1 minute after the fire is detected to be 1m or higher).

In other words, if a able-bodied person is evacuating and there is a person requiring assistance nearby, the able-bodied person will be notified of the evacuation information after a set time delay has elapsed.

(3) Spatial priority: Even after implementing the evacuation guidance for people requiring assistance as described in (1) and (2), if there are people requiring assistance around able-bodied people, an evacuation route for able-bodied people will be set up to avoid those people requiring assistance.

In other words, when able-bodied people evacuate and there are people requiring assistance nearby, the evacuation route for the able-bodied people will be set to avoid the evacuation route for those people requiring assistance.

In the above manner, information to be transmitted including evacuation routes according to the level of the disaster is calculated. As a result, priority is given to evacuation of those requiring assistance. Among these, (3) spatial priority is shown in Figure 7. In Figure 7, a person requiring assistance who needs to use a wheelchair and an able-bodied person evacuate from the office area at the same time, and the evacuation route for the able-bodied person requiring assistance is calculated to be the shortest possible. In contrast, although the able-bodied person is closer to the upper exit, the evacuation route calculation function 33 calculates an evacuation route for them to leave the office area from a lower exit and evacuate to the stairs so as not to overlap with the evacuation route for the person requiring assistance.

Next, the output contents (display screen) of the information output unit 4 in this embodiment will be described. Here, an example will be described of outgoing information for the person requiring assistance and the able-bodied person when they are in the same area. FIG. 8A is a diagram showing the screen of the evacuee terminal 41 of the person requiring assistance, which realizes the priority evacuation of the person requiring assistance in this embodiment. Here, the display is made in an appropriate notification method according to the attributes of the person in the building using the evacuee terminal 41. For example, able-bodied people are notified of the detection of a disaster by an audio alarm or a screen such as that shown in FIG. 8A. In contrast, hearing-impaired people are notified by an audio alarm, but by a mobile phone vibration or a screen such as that shown in FIG. 8A. Furthermore, visually impaired people are provided with an audio alarm and audio evacuation guidance.

When a disaster occurs, it is desirable to switch to a disaster notification screen, regardless of the usage status of the evacuee terminal 41, as in the case of an emergency earthquake alert. The disaster notification screen also displays the type of disaster, the extent of the disaster, the evacuation destination, and a map of the floor on which the occupants are currently located. The map shows the location of the disaster (if it occurred on the same floor), the current location of the occupants, and the evacuation route.

For example, if a fire breaks out on the third floor of a building that has an emergency elevator, the level of the disaster for the person requiring assistance is determined to be "evacuation outside the building required." As a result, the person requiring assistance who is using the evacuee terminal 41 is in an office area on the third floor and needs to use a wheelchair. For this reason, they need to take the emergency elevator down to the first floor and evacuate to outdoors. The notification screen then displays the following information with the words "fire" and an illustration: the disaster level of "evacuation outside the building required" and the evacuation destination of "→ outdoors" are displayed, and on the map of the third floor of the current location, a fire has broken out near the stairs in the lower left, and the evacuation route from the office area of the current location to the emergency elevator is indicated by a blue dotted line.

Furthermore, if the person requiring assistance is visually impaired, they will not be able to see the evacuation route on the screen. For this reason, the system uses registered information about the occupants of the building to guide them to the evacuation route based on their current location, and provides voice guidance such as "Turn left and go forward five meters," "After exiting the door, turn right and go forward two meters," and "Take the emergency elevator."

Next, the screen of the evacuee terminal 41 of able-bodied people around the person requiring assistance will be explained using Figure 8B. Able-bodied people are notified by an audio alarm and a notification screen. The notification screen displays the type of disaster, the extent of the disaster, the evacuation destination, and a map of the floor on which people are currently located.

The map also shows the location of the disaster (if it occurs on the same floor), the current location of people in the building, and the location of people requiring assistance nearby who are not on the evacuation route. This allows able-bodied people to be guided so as not to impede the evacuation of people requiring assistance, as the location of people requiring assistance is known and the evacuation route avoids them.

For example, a fire breaks out on the third floor of a building with an emergency elevator, and the level of the disaster for able-bodied people is judged to be "evacuation within the building is required." The able-bodied person using the evacuee terminal 41 is in an office area on the third floor, and is surrounded by people who require assistance. For this reason, it is necessary to evacuate by avoiding the evacuation route of the people who require assistance. Therefore, the notification screen displays the disaster level of "evacuation within the building is required" with the words and illustrations of "fire" and the evacuation destination of "→1F." Also, on the notification screen, a fire has broken out near the stairs in the lower left on the map of the third floor where the person is currently located, and the evacuation route from the office area of the current location to the stairs is shown with a purple dotted line. Furthermore, people who require assistance who are nearby are shown with a blue mark. Also, because the people who require assistance nearby use the upper exit of the office area, the able-bodied person using the evacuee terminal 41 can evacuate using the lower exit of the office area.

Finally, using Figure 9, we will explain a case where a rescue call is made during evacuation when necessary facilities are not available to those in the building or when they are unable to evacuate outside due to a disaster. Figure 9 is a diagram showing the screen of an evacuee terminal 41 making a rescue call in this embodiment.

Here, it is assumed that if a fire breaks out and the fire spreads to the vicinity of the entrance through which people in the building escape, they will be unable to escape outside and will be unable to move inside the room. Alternatively, it is assumed that an earthquake causes a wall at the end of the passageway to collapse during evacuation, making it impossible to escape outside and preventing people from moving along the passageway. It is assumed that the location of the evacuee terminal 41 used by the people in the building (evacuee) is not moving along the evacuation route but is detected to be remaining within a certain range. This detection can be performed by the GPS function of the evacuee terminal 41. When this detection is made, 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 specified time of 60 seconds or less, the evacuee terminal 41 will determine that the person has lost consciousness or that it is difficult to manually call for rescue, and will automatically call for rescue. If the people in the building do not want to call for rescue but call for rescue by mistake, or if they are able to evacuate during the rescue call, it is also possible to cancel the rescue.

This concludes the description of this embodiment, but the present invention is not limited to this embodiment. For example, the evacuation information calculation unit 3 may create and notify, as transmission information, operation control commands for elevators and emergency elevators according to the evacuation route. As a result, the elevators and emergency elevators will be able to wait for people in the building on the relevant floor in the event of a disaster.
