Summary of the Invention

Problems to be Solved by the Invention

[0004] Especially in high-rise buildings, since there are many people in the building, congestion occurs near or inside the emergency stairs during evacuation, and the evacuation takes a long time. The following points can be considered as factors that further exacerbate the congestion.

[0005] First, people flow into the stairs from the middle floors. In addition, many of the emergency doors installed in the emergency stairs open to the emergency stair side, and when people on the middle floors open the emergency doors, the flow of people deteriorates. Second, people with little physical strength originally have a slow speed of descending the stairs, and the speed may become even slower during the descent, and there may be a need to rest during evacuation.

[0006] On the other hand, although the system of Patent Document 1 discloses a technique for generating an evacuation plan for the entire building, it is not a system that takes into account individual circumstances to relieve congestion and generates an evacuation plan for each individual.

[0007] This disclosure was made to solve the above-mentioned problems, and its purpose is to provide an evacuation plan generation device and a control method therefor that can alleviate congestion during evacuation from a building and enable the evacuation to be completed quickly. [Means for solving the problem]

[0008] The evacuation plan generation device described herein is a device that generates evacuation plans for each of several people staying in a building. The evacuation plan generation device comprises a communication unit and a processing unit. The communication unit acquires the physical condition information and current location of each of the several people. The processing unit selects an evacuation route according to the physical condition information and current location of each of the several people and generates an evacuation plan for each of them. Each of the several people's evacuation plans is a plan for each of the several people to evacuate from the building by moving along an evacuation route, including the use of stairs, after leaving their current location. The communication unit transmits each of the several people's evacuation plans to terminals that each of the several people possess.

[0009] The control method relating to this disclosure is a control method for an evacuation plan generation device that generates evacuation plans for each of several people staying in a building. The control method includes the steps of acquiring the physical fitness information and current location of each of the several people, and selecting an evacuation route according to the physical fitness information and current location of each of the several people to generate an evacuation plan for each of the several people. Each of the several people's evacuation plans is a plan for each of the several people to evacuate from the building by moving along an evacuation route, including the use of stairs, after leaving their current location. The control method further includes the step of transmitting each of the several people's evacuation plans to a terminal carried by each of the several people. [Effects of the Invention]

[0010] According to this disclosure, congestion during evacuation from buildings can be alleviated, and evacuation can be completed quickly. [Brief explanation of the drawing]

[0011] [Figure 1] This is a diagram illustrating the outline of the evacuation plan generation system. [Figure 2]This diagram shows the hardware configuration of the evacuation plan generation system. [Figure 3] This diagram shows an example of how people evacuate inside a building. [Figure 4] This is a diagram showing an example of a table. [Figure 5] This figure shows an example of what is displayed on an employee's terminal during an evacuation. [Figure 6] This figure shows an example of what is displayed on an employee's terminal during an evacuation. [Figure 7] This is a flowchart for the evacuation plan generation process. [Figure 8] This is a flowchart of the evacuation process. [Modes for carrying out the invention]

[0012] The embodiments will be described below with reference to the drawings. In the following description, identical parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0013] Figure 1 is a schematic diagram of the evacuation plan generation system 1. The evacuation plan generation system 1 is installed in building 2. The evacuation plan generation system 1 comprises a server device 100, an equipment management device 200, and multiple wireless communication devices 210. Building 2 has N floors (for example, 20 floors), and Figure 1 shows the Nth floor.

[0014] The server device 100 is one embodiment of an evacuation plan generation device. The server device 100 is a device that generates evacuation plans for each of the multiple people staying in building 2 (in this case, all employees 6 who are working in building 2). Each evacuation plan for all employees 6 is a plan for each employee 6 to evacuate from building 2 by moving along an evacuation route that includes the use of stairs after leaving their current location. Note that the evacuation route is not limited to using only stairs, but may also include the use of elevators in some parts.

[0015] In this embodiment, building 2 is an office building, but it may also be a building such as a hospital or a school. One or more companies are located in building 2. Employees 6 of each company work in the living quarters provided in each area on each floor.

[0016] The area on the east side of building 2 is referred to as the "east area". The area on the west side of building 2 is referred to as the "west area". On the east side of the east area, there is an "east staircase", which is an emergency staircase that can be accessed by stairs from the 1st floor to the Nth floor. On the west side of the west area, there is a "west staircase", which is an emergency staircase that can be accessed by stairs from the 1st floor to the Nth floor. Between the east area and the west area, there is a "central staircase", which is an emergency staircase that can be accessed by stairs from the 1st floor to the Nth floor.

[0017] In FIG. 1, the Nth floor east area 40, the east staircase 41, and the central staircase 42 are shown. There is a wall 62 between the Nth floor east area 40 and the east staircase 41, and by opening the door 61, it is possible to move from the Nth floor east area 40 to the east staircase 41. There is a wall 62 between the Nth floor east area 40 and the central staircase 42, and by opening the door 61, it is possible to move from the Nth floor east area 40 to the central staircase 42. Although not shown, on the west side of the central staircase 42, there are provided the Nth floor west area and the west staircase.

[0018] A plurality of employees 6 work in the Nth floor east area 40. Employee 6 always carries a terminal 3 (for example, a smartphone) owned by employee 6, and also always wears a smartwatch 4 on the wrist. The smartwatch 4 can measure the heart rate of employee 6. The terminal 3 is always in communication with the wireless communication device 210, and thereby the current position of employee 6 can be identified. Details of the terminal 3 and the smartwatch 4 will be described later.

[0019] FIG. 2 is a diagram showing the hardware configuration of the evacuation plan generation system 1. The server device 100 includes a processor 101 as a processing unit, a memory 102, and a communication IF (Interface) 103 as a communication unit. These exchange various data through a communication path.

[0020] The processor 101 is, for example, a CPU (Central Processing Unit). The memory 102 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). Note that the memory 102 may include a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The processor 101 expands and executes a program stored in the ROM or the storage device in the RAM. This program describes the processing to be executed by the server device 100. The communication IF 103 is an input / output device for exchanging data with various devices connected to the server device 100.

[0021] The device management device 200 is a device that manages various devices installed in Building 2, including a plurality of wireless communication devices 210. The device management device 200 transmits information acquired from various devices to the server device 100. The device management device 200 also includes a processor 101, a memory 102, and a communication IF (Interface) 103. These exchange various data through a communication path. These functions are equivalent to those of the server device 100.

[0022] The plurality of wireless communication devices 210 are installed at an appropriate distance from the ceilings of all areas and stairways (emergency stairways) on the 1st to Nth floors inside Building 2. The plurality of wireless communication devices 210 are configured to communicate with a wireless communication device 211 provided in a terminal 3 held by an employee 6 and to be able to acquire the position and information of the terminal 3 (employee 6).

[0023] The wireless communication device 211 outputs a signal for detecting the position of the terminal 3 (employee 6) using, for example, a communication method compliant with the BLE (Bluetooth Low Energy, "Bluetooth" is a registered trademark) communication standard. Instead of the BLE communication standard, a communication method compliant with the UWB (Ultra Wide Band) communication standard may be used.

[0024] Multiple wireless communication devices 210 use a communication method that conforms to the same communication standard as wireless communication device 211 to receive signals transmitted from the wireless communication device 211 of terminal 3 and detect the received signal strength. The location of terminal 3 (employee 6) can be detected from the received signal strength at each wireless communication device 210. The wireless communication devices 210 output the received signal strength of the signal received from terminal 3 to the equipment management device 200. As a result, the equipment management device 200 identifies the current location of terminal 3 based on the received signal strength at each wireless communication device 210. The server device 100 obtains the location information and other information of terminal 3 (employee 6) from the equipment management device 200. The wireless communication devices 210 may be installed on a wall.

[0025] Terminal 3 comprises a wireless communication device 211, a control unit (not shown), and a display unit 212. The control unit, like the server device 100, is configured to include a processor, memory, and a communication interface. The location of terminal 3 (employee 6) may be determined using cameras installed at equal intervals on the ceiling.

[0026] Each employee 6 carries a terminal 3 provided by the company at all times. Terminal 3 is, for example, a smartphone. The server device 100 can obtain employee information such as the location information and ID of employee 6 via the wireless communication device 210, based on the information transmitted by the wireless communication device 211 of terminal 3.

[0027] Smartwatch 4 is a smartwatch worn by employee 6 who uses terminal 3. Although not shown in the diagram, smartwatch 4 also consists of a processor, memory, and a communication interface. It is configured to enable bidirectional communication between smartwatch 4 and terminal 3.

[0028] Smartwatch 4 is equipped with an optical heart rate sensor 221. The heart rate sensor 221 measures the heart rate of employee 6. The display unit 222 of Smartwatch 4 can display various information, such as heart rate, in addition to the current time. The measured heart rate information is transmitted to terminal 3.

[0029] Terminal 3 transmits heart rate information to the device management device 200 via the wireless communication device 210. The device management device 200 transmits the acquired heart rate information to the server device 100. The server device 100 and terminal 3 may be connected via a network such as the Internet. Terminal 3 may also transmit heart rate information to the server device 100 via the Internet.

[0030] Figure 3 shows an example of an evacuation within Building 2. In this embodiment, an evacuation drill is conducted in Building 2 beforehand. During the evacuation drill, employee 6 practices evacuating from their workspace to the first floor using the emergency staircase. During the evacuation drill, employee 6's heart rate and walking speed (also referred to as "walking speed") are measured, and employee 6's physical fitness is determined based on this information. Note that, not limited to evacuation drills, heart rate and walking speed may be measured when normally going up and down stairs, and employee 6's physical fitness may be determined based on this information.

[0031] Then, in the event of a disaster such as a fire or earthquake, an evacuation from Building 2 will actually take place. At this time, the server device 100 will generate an evacuation plan for each of the employees 6 who are staying in Building 2. Each employee 6 will begin evacuating from the place where they were staying when the disaster occurred (their current location), but basically, they will evacuate from the area where their office is located. The generated evacuation plan will be sent to the terminal 3 that the employee 6 is carrying. The employee 6 will check the evacuation plan on the terminal 3 and evacuate according to the plan.

[0032] Employee 6, who works in a room located in the east area and whose physical fitness was judged to be "standard" in a pre-conducted evacuation drill (hereinafter referred to as "Employee 6 with standard physical fitness in the east area"), will have an evacuation plan generated to evacuate using the east staircase. The evacuation route using the east staircase will be referred to as the "east route."

[0033] Employee 6, who works in a room located in the west area and whose physical fitness was judged to be "standard" in a pre-conducted evacuation drill (hereinafter referred to as "Employee 6 with standard physical fitness in the west area"), will have an evacuation plan generated to evacuate using the west staircase. The evacuation route using the west staircase will be referred to as the "west route."

[0034] On the other hand, employee 6, who works in a room located in the east or west area and was judged to have "low" physical strength during a pre-conducted evacuation drill (hereinafter referred to as "employee 6 with low physical strength"), will have an evacuation plan generated to evacuate using the central staircase. The evacuation route using the central staircase will be referred to as the "route for vulnerable persons."

[0035] Let's take the evacuation via the east route as an example. First, 6 employees with standard physical fitness in the east area of ​​the Nth floor begin evacuating via the east staircase. Next, the 6 employees with standard physical fitness in the east area of ​​the N-1 floor begin evacuating so that the first evacuee (leading) of the east area of ​​the N-1 floor follows the last evacuee (rear) of the east area of ​​the Nth floor.

[0036] Next, the evacuation of the six employees with standard physical fitness in the N-2 East area begins, so that the last of the six employees with standard physical fitness in the N-1 East area is followed by the first of the six employees with standard physical fitness in the N-2 East area. In this way, the evacuation plan is created so that evacuation proceeds from the top floor upwards, in the order of N floor, N-1 floor, N-2 floor, N-3 floor, and so on, with the last of the employees on one floor following the first of the employees on the floor below.

[0037] As a result, the server device 100 adjusts the timing of people entering the stairs so that the flow of people going down the stairs does not overlap with the flow of people entering the stairs, and generates an evacuation plan for each of the employees 6.

[0038] However, for example, if the evacuation of all employees with standard physical strength in the east area of ​​the 2nd floor is completed by the time the first employee with standard physical strength in the east area of ​​the Nth floor reaches the 2nd floor, then the evacuation of employees with standard physical strength in the east area of ​​the Nth floor and the east area of ​​the 2nd floor may be started simultaneously.

[0039] Employees 6 with standard physical strength in the west area who evacuate via the west route, and employees 6 with low physical strength who evacuate via the vulnerable route, also evacuate in the same procedure. In this case, employees 6 with standard physical strength on the Nth floor of the east area via the east route, employees 6 with standard physical strength on the Nth floor of the west area via the west route, and employees 6 with low physical strength on the Nth floor via the vulnerable route may start evacuating simultaneously.

[0040] Moreover, rest areas are provided on multiple floors among the 1st to Nth floors. In this example, rest areas are installed on the A floor and the B floor. Here, 1st floor < A floor < B floor < Nth floor.

[0041] Employees 6 who evacuate via the vulnerable route are planned to rest in the rest areas on the A floor and the B floor in advance. In principle, employees 6 who evacuate via the east route or the west route do not rest in the rest area. However, if the heart rate of employee 6 exceeds a predetermined value or the walking speed becomes less than or equal to a predetermined value during evacuation, an instruction is given to rest in the nearest rest area.

[0042] Also, for example, assume that immediately after the start of evacuation, employees evacuate to the lower floors in the order of the A-|st| floor, the A-2nd floor, ···, the 2nd floor. If the flow of employees 6 on these lower floors overlaps with the flow of employees 6 coming down from the Nth floor on the upper floor, all employees 6 on the Nth floor can be moved to the A floor and made to rest on the A floor until the evacuation of the lower floors is completed.

[0043] In this way, when allowing people to flow in from the lower floors, by restricting (resting) the movement of evacuees from the upper floors, a situation where the flows of people overlap can be avoided. Furthermore, by resting on the A floor, the physical strength of employees 6 on the Nth floor is restored. Even for employees 6 with standard physical strength, by taking a rest on the way, they can descend the stairs faster than when there is no rest.

[0044] Figure 4 shows an example of Table 91. For each employee 6, Table 91 records the employee 6's "ID", the employee 6's "heart rate" and "walking speed" measured during the prior evacuation drill, the "physical fitness" determined from the heart rate and walking speed, the "floor" and "location" (current position) where employee 6 is staying at the time of the disaster, the "departure time" for evacuation, the "entry time" to the emergency staircase of the evacuation route, the "evacuation route", the "evacuation walking speed" designated during evacuation, the "rest floor", and the "rest time".

[0045] For example, employee 6, whose ID is "X1," was determined to have a "normal" heart rate and "normal" walking speed during a pre-evacuation drill. If a heart rate above a predetermined value is measured during the pre-evacuation drill, the heart rate will be determined to be "high." On the other hand, if a heart rate above a predetermined value is not measured, the heart rate will be determined to be "normal." If a walking speed below a predetermined value is measured during the pre-evacuation drill, the walking speed will be determined to be "slow." On the other hand, if a walking speed below a predetermined value is not measured, the walking speed will be determined to be "normal."

[0046] If both heart rate and walking speed are judged to be "standard," then "physical fitness" is judged to be "standard." On the other hand, if the heart rate is judged to be "high" or the walking speed is judged to be "slow," then physical fitness is judged to be "low." Note that the physical fitness information measured is not limited to heart rate; other physical information may also be used.

[0047] Furthermore, the room of employee 6 with ID "X1" is located in the "Nth floor east area". At the time of the disaster and the actual evacuation, employee 6 was determined to be at location "P1" based on information acquired by the wireless communication device 210. Location "P1" is located within the "Nth floor east area".

[0048] Furthermore, employee 6 with ID "X1" will depart at "T11" when starting the evacuation, enter the room at "T21", and use the "East Staircase" as their evacuation route. For example, employee 6 with ID "X1" will begin evacuating at 14:00 (departing from their room in the East Area on the Nth floor where they work) and enter the East Staircase on the Nth floor at 14:03. At that time, employee 6 with ID "X1" is instructed to evacuate at a standard walking speed and will not take a break on the break floor.

[0049] Employee 6 with ID "X2" also has a room in the east area of ​​the Nth floor and is staying at location "P2" within the east area of ​​the Nth floor. Their physical condition is judged to be "standard," and their evacuation schedule is almost the same as employee 6 with ID "X1," but their departure time is "T12" and their entry time is "T22." Even though both employees are in the same "east area of ​​the Nth floor," their departure and entry times are slightly different. This allows for smooth entry to the east staircase without congestion.

[0050] On the other hand, employee 6 with ID "X3" has a room in the east area of ​​the Nth floor, but has a high heart rate and slow walking speed, so is judged to have "low" physical strength. For this reason, the "central staircase," which is a route for vulnerable people, has been designated as the evacuation route. Employee 6 with ID "X3" has a departure time of "T13" and an entry time of "T23". In addition, employee 6 with ID "X3" with low physical strength is instructed to evacuate at a slow walking speed and to rest on the rest floors of the B and A floors. The rest times on the B and A floors are also specified. For example, "14:10~14:15" on the B floor and "14:20~14:25" on the A floor (or, "5-minute rest upon arrival on the B floor" would also be acceptable).

[0051] Figures 5 and 6 show examples of displays on employee 6's terminal 3 during evacuation. Figure 5 shows the display information on the display unit 212 of terminal 3 held by employee 6 with ID "X3", as explained using Figure 4.

[0052] As shown in Table 91, the display unit 212 of terminal 3 shows that the ID is "X3". In addition, preliminary information from a prior evacuation drill shows that physical strength is "low", heart rate is "high", and walking speed is "slow". Accordingly, the actual evacuation plan shows that the current location is "Nth floor East area P3", the evacuation route is "central staircase", the designated walking speed is "slow", the departure time is "T13", the entry time is "T23", and the resting floors are "B floor, A floor".

[0053] Then, once the evacuation actually begins, the display unit 212 of terminal 3 displays real-time information. In this example, the current time during the evacuation is "**", and it shows that they have now walked to "N-1".

[0054] Furthermore, the heart rate measured by the heart rate sensor 221 of smartwatch 4 is above a predetermined value, so the heart rate is judged to be "high". Also, the walking speed calculated from the change in location information of terminal 3 is below a predetermined value, so the walking speed is judged to be "slow". In addition, employee 6 with ID "X3" is currently on the N-1 floor, so they are instructed to take a break on the nearest break floor, "B floor", along with the duration of the break.

[0055] Figure 6 shows the display information on the display unit 212 of terminal 3, which is owned by employee 6 with ID "X1," as explained using Figure 4. The ID, prior information, and evacuation plan are as recorded in Table 91 in Figure 4, and there are no plans for breaks on the rest floor.

[0056] When the evacuation actually begins, the display unit 212 of terminal 3, held by employee 6 with ID "X1", displays real-time information. In this example, the current time during the evacuation is "**", and it shows that they have now walked to "A+2 floor".

[0057] At the start of the evacuation, the heart rate and walking speed were judged to be "normal." However, during the evacuation, the heart rate increased and exceeded the predetermined value, so it was judged to be "high." Although the walking speed is "normal," the heart rate was judged to be "high," so new instructions were given to take a rest in the rest area. Currently, as they are walking on floor A+2, they have been instructed to take a rest on the nearest rest floor, "floor A."

[0058] The following explanation will use a flowchart. Figure 7 is a flowchart of the evacuation plan generation process. Hereafter, "step" will also be simply referred to as "S".

[0059] When a disaster occurs, the server device 100 acquires the physical fitness information (walking speed, heart rate) and current location of all employees 6 staying in building 2 in S100. The physical fitness information of each employee 6 includes the heart rate measured by the heart rate sensor 221 of the smartwatch 4 worn by each employee 6, and the walking speed (walking speed) measured from the location information (measured by the wireless communication device 210) of each employee 6.

[0060] Heart rate may be a specific numerical value, or it may be expressed as a level such as "high" or "normal." Walking speed may be a specific numerical value, or it may be expressed as a level such as "normal" or "slow."

[0061] Physical fitness information is obtained from "walking speed" and "heart rate" in Table 91. This information was measured during the evacuation drill. Current location is the current location information of each employee measured by the wireless communication device 210 when the disaster occurred. For example, employee 6, whose ID is "X1", has a physical fitness level of "standard", a "standard" "heart rate", and a current location of "Nth floor East area P1".

[0062] An example of Table 91 is shown in Figure 4. At this point, Table 91 records basic information such as "ID," "heart rate" and "walking speed" measured during the evacuation drill, but no other information is recorded. The current location information obtained above is recorded (saved) in Table 91. For example, it is recorded that employee 6, whose ID is "X1," is on the "Nth floor" and is staying in "East Area P1."

[0063] In step S101, the server device 100 determines and sets the physical fitness of each employee 6 based on their walking speed and heart rate during the evacuation drill. For example, as shown in the example explained using Figure 4, the physical fitness of employee 6 with ID "X1" is determined to be "standard," and the physical fitness of employee 6 with ID "X3" is determined to be "low," and this information is recorded in table 91.

[0064] The server device 100 selects evacuation routes for each employee 6 based on their individual physical condition information (walking speed, heart rate) and current location, and generates individual evacuation plans for each employee 6. Specifically, in S102, the server device 100 sets the evacuation route for employees 6 with low physical condition to the route for vulnerable persons (central staircase). For example, the "evacuation route" for employee 6 with ID "X3" is set to "central staircase," and their evacuation walking speed is set to "slow," and this information is recorded in table 91.

[0065] The server device 100 generates an evacuation plan for each employee 6, instructing them to rest in a rest area along the evacuation route if their physical strength, determined from their individual physical strength information, falls below a predetermined standard. Specifically, in S103, the server device 100 sets a rest area (rest floor) for the employee 6 with low physical strength. For example, the rest floor for employee 6 with ID "X3" is set to "B floor, A floor," and a rest time is also set, and this information is recorded in table 91.

[0066] In S104, the server device 100 sets the evacuation route for employee 6, whose physical strength is standard, to the emergency staircase closest to their current location (the area where they are staying). For example, for employee 6, whose ID is "X1" and who is in the east area, the "evacuation route" is set to "east staircase," and their evacuation walking speed is set to "standard." This information is recorded in table 91. In this way, an evacuation route is selected according to employee 6's physical strength, and an evacuation route close to employee 6's current location is selected.

[0067] In S105, the server device 100 calculates the number of evacuees for each floor for each evacuation route. For example, based on the information in table 91, the server device 100 aggregates the number of employees 6 who use the east staircase on the Nth floor, the number of employees 6 who use the central staircase on the Nth floor, and the number of employees 6 who use the west staircase on the Nth floor. The same aggregation is performed for floors N-1 to 1.

[0068] The server device 100 generates individual evacuation plans for all employees 6 by adjusting the timing of the second flow of people entering the stairs from the floor so that the first flow of people descending the stairs and the second flow of people entering the stairs from the floor do not overlap. Specifically, it does the following:

[0069] In S106, the server device 100 adjusts the entry time of employees 6 entering the emergency staircase from the floor so that the flow of employees 6 descending the emergency staircase does not overlap with the flow of employees 6 entering the emergency staircase from the floor, and generates an evacuation plan for each employee 6 so that the evacuation is completed in the shortest possible time.

[0070] For example, if the evacuation start time for the entire building 2 is T11, the departure time for employee 6, who will be the first to enter the east staircase on the Nth floor, is set to "T11". The time "T21" when this employee reaches the east staircase on the Nth floor, assuming they walk at a "standard" evacuation pace, becomes the "time of entry into the east staircase on the Nth floor". The departure and entry times for employee 6 in the east area of ​​the Nth floor are determined by slightly staggering the times to prevent congestion on the Nth floor east area and the east staircase on the Nth floor.

[0071] The departure and entry times for employee 6 are determined so that the last employee 6 entering the east staircase on the Nth floor (all the evacuated people counted above) descends the stairs on the Nth floor and passes the stairs on the N-1 floor, at which point the first employee 6 using the east staircase on the N-1 floor follows. In this way, it is possible to adjust the entry time of employee 6 entering the east staircase on the N-1 floor so that the flow of employees 6 descending from the east staircase on the Nth floor does not overlap with the flow of employees 6 entering the east staircase on the N-1 floor from the east area of ​​the N-1 floor. By limiting the number of people flowing into the staircase from the N-1 floor in this way, congestion does not occur, and employees 6 from the N floor can descend faster. The time when the last employee 6 entering the east staircase on the Nth floor arrives on the 1st floor is the time when the evacuation of employees 6 using the east staircase on the Nth floor is completed.

[0072] If the flow of people descending the stairs and the flow of people entering the stairs are not coordinated as described above, it may become impossible to enter the stairs, and people may get stuck at the entrance to the stairs. For example, if the door to the stairs opens inward, and the stairs are crowded with 6 employees descending, the people may get in the way and prevent the door to the stairs from opening (a congestion on the stairs). If the coordination is done as described above, people can enter the stairs smoothly.

[0073] Furthermore, the methods for adjusting pedestrian flow are not limited to those described above. For example, entry and exit times could be adjusted so that the flow of people descending the stairs and the flow of people entering the stairs alternate. Alternatively, the amount of people descending the stairs could be reduced to just enough space for the door to the stairs to open, and the amount of people entering the stairs could also be adjusted to ensure that these flows merge appropriately.

[0074] Using a similar method, the timing of the last employee 6 entering the east staircase on the N-1 floor descending the stairs on the N-1 floor and passing through the stairs on the N-2 floor, and the timing of their arrival on the 1st floor (the evacuation completion time for employee 6 using the east staircase on the N-1 floor) can be calculated. In this way, the departure time, entry time, and evacuation completion time for employee 6 using the east staircase on floors below the N-2 floor can be calculated. The same calculations are performed for evacuation routes using the west staircase and the central staircase. If breaks are taken on rest floors, the break time is also taken into account in the calculation. By following the above procedure, all the information in Table 91 shown in Figure 4 is set.

[0075] Figure 8 is a flowchart of the evacuation execution process. After executing the evacuation plan generation process, in S201, the server device 100 transmits each employee 6's individual evacuation plan (the evacuation plan recorded in table 91) to the terminal 3 that each employee 6 possesses.

[0076] For example, information about employee 6, whose ID is "X3", is read from table 91 and sent to terminal 3, which is owned by employee 6, whose ID is "X3". As a result, the information shown in Figure 5 is displayed on terminal 3, which is owned by employee 6, whose ID is "X3". Employee 6 then evacuates according to the evacuation plan displayed on terminal 3.

[0077] In S202, the server device 100 acquires location information and heart rate information for each employee 6. As described above, location information identified based on information transmitted by the wireless communication device 211 of terminal 3, and heart rate information measured by the heart rate sensor 221 of smartwatch 4 are acquired.

[0078] If the server device 100 detects a decrease in the average movement speed along the evacuation route in S203, it delays the departure time from the waiting area. For example, based on the location information of employee 6 acquired in S202, the server device 100 calculates the average movement speed of employee 6 using the east staircase on the Nth floor. If this average movement speed becomes slower than the standard evacuation walking speed by a certain amount, the server device 100 delays the departure time of employee 6 evacuating via the east staircase on the N-1st floor by a certain amount of time to prevent congestion on the emergency stairs, etc.

[0079] The server device 100 determines whether the physical fitness of each employee 6 during the evacuation has fallen below a predetermined standard, based on their walking speed and heart rate during the evacuation. The communication IF 103 sends a command to the terminal 3 held by the person whose physical fitness has been determined to have fallen below a predetermined standard (determined to be "low"), instructing them to take a rest at a rest area along the evacuation route.

[0080] Specifically, in S204, the server device 100 determines that an employee 6 whose heart rate exceeds a predetermined value or whose walking speed falls below a predetermined value has "low" physical fitness, and instructs the employee 6 to take a break in the nearest rest area. For example, as shown in Figure 6, because the employee's heart rate exceeded a predetermined value while walking, the server device 100 sends an instruction to take a break in the nearest rest area (rest floor), "Floor A," and this information is displayed on the terminal 3 of employee 6, whose ID is "X1."

[0081] The server device 100 terminates the evacuation process if the evacuation of all employees 6 is complete (YES in S205). On the other hand, if the evacuation of employees 6 is not complete (NO in S205), the server device 100 returns to S201. Based on the detected location information, it is determined that the evacuation of all employees 6 is complete when it is determined that all employees 6 have arrived on the first floor.

[0082] In this embodiment, the heart rate is set to two levels, "high" and "standard," but it is not limited to these, and may be set to three or more levels. The walking speed is also set to two levels, "standard" and "slow," but it is not limited to these, and may be set to three or more levels. Physical fitness is also set to two levels, "standard" and "low," but it is not limited to these, and may be set to three or more levels. Furthermore, if there are many evacuation routes, the routes may be further divided according to the physical fitness evaluation values ​​of multiple levels, and the resting floors may also be divided into multiple levels, such as the 1st floor, 2nd floor, and 3rd floor, according to physical fitness. In addition, the walking speed during evacuation may be instructed to be slightly slower than the standard walking speed. By doing so, it is possible to prevent a decline in physical fitness as much as possible.

[0083] As described above, the server device 100, which is one embodiment of the evacuation plan generation device, is a device that generates evacuation plans for each of the multiple people (all employees 6) staying in building 2. The server device 100 comprises a communication IF 103 as a communication unit and a processor 101 as a processing unit. The communication IF 103 acquires the physical fitness information (walking speed, heart rate) and current location of each of the employees 6. The processor 101 selects an evacuation route according to the physical fitness information and current location of each of the employees 6 and generates an evacuation plan for each of the employees 6. Each evacuation plan for each of the employees 6 is a plan for each of the employees 6 to evacuate from building 2 by moving along an evacuation route, including the use of stairs, after leaving their current location. The communication IF 103 transmits each evacuation plan for each of the employees 6 to a terminal 3 that each of the employees 6 possesses.

[0084] This ensures that evacuation routes are selected according to each employee's physical strength, preventing employees with lower physical strength from hindering the movement of employees with average physical strength, and allowing for the selection of appropriate evacuation routes based on their current location. In this way, by generating an evacuation plan using stairs for each employee, taking into account their individual circumstances such as their physical strength and current location, congestion during evacuation from Building 2 can be alleviated, and evacuation can be completed quickly.

[0085] Processor 101 generates individual evacuation plans for all employees 6 by adjusting the timing of the second flow of people entering the stairs from the floor so that the first flow of people descending the stairs does not overlap with the second flow of people entering the stairs from the floor. In this way, congestion caused by overlapping flow of people descending the stairs and entering the stairs is prevented, further reducing congestion during evacuation from building 2 and enabling the evacuation to be completed more quickly.

[0086] The processor 101 generates an evacuation plan for each employee 6, instructing them to rest at a rest area along the evacuation route if their physical strength, determined from their individual physical strength information, falls below a predetermined standard. This proactively encourages employees with low physical strength to rest, reducing congestion caused by slower walking speeds and enabling a quicker evacuation.

[0087] Each employee 6's physical fitness information includes their heart rate measured by a smartwatch 4 worn by each employee 6, and their walking speed measured from their location information. The processor 101 determines each employee 6's physical fitness based on their walking speed and heart rate during the evacuation drill. This allows for an accurate estimation of physical fitness based on heart rate and walking speed during evacuation, preventing employees 6 with low fitness levels from hindering the movement of employees 6 with average fitness levels. It also allows for appropriate rest for employees 6 with low fitness levels.

[0088] The processor 101 determines whether the physical fitness of each employee 6 during evacuation has fallen below a predetermined standard based on their walking speed and heart rate during evacuation. The communication IF 103 sends a command to the terminal 3 held by the person whose physical fitness has been determined to be below the predetermined standard (slow) to take a rest at a rest area along the evacuation route. Even if an employee 6 has standard physical fitness, their physical condition may change along the way, causing their physical fitness to decline and making it impossible to walk normally. By configuring the system as described above, a decline in the physical fitness of an employee 6 can be detected quickly, and they can be given an appropriate rest.
