Embodiment 1.

Fig. 1 is a configuration diagram of an evacuation support system 1 according to embodiment 1.

The evacuation support system 1 is applied to a facility 2. The evacuation support system 1 is a system for supporting evacuation of an evacuee such as a user of the facility 2 when a disaster such as a fire occurs in the facility 2.

The facility 2 is, for example, a residential facility, a commercial facility, an accommodation facility, an office building, a public facility, a complex facility, or the like. The users of the facility 2 include, for example, the residents, visitors, guests or workers of the facility 2, and the like. The facility 2 includes one or more buildings 3. In this example, the facility 2 includes a plurality of buildings 3. Each building 3 has a plurality of floors. In each building 3, a retreat floor is set in advance. The evacuation floor is a floor leading to an evacuation destination when the disaster is evacuated. The evacuation destination is, for example, an outdoor place of the building 3. The evacuation floor is, for example, a floor set in advance in the building 3. The evacuation floor is, for example, a hall floor. In this example, the evacuation floor is set to be common to a plurality of buildings 3 of the facility 2.

In the installation 2 an elevator system 4 is applied. A plurality of banks 5 of elevator systems 4 are provided in the installation 2. Each ladder bank 5 is provided in any building 3 of the facility 2. Each bank 5 includes one or more elevators 6. Each elevator 6 includes a car 7 and a control panel 8. The car 7 is a device for transporting a user of the facility 2 between a plurality of floors by traveling in a vertical direction. The control panel 8 controls operations such as traveling of the car 7. Each bank 5 is provided with a landing on each floor of the building 3 on which the bank 5 is installed. The landing for each bank 5 is a place where a user can get on and off the car 7 of any elevator 6 of the bank 5. At each landing, a landing operating panel 9 of the elevator 6 included in the bank 5 is provided. The landing operation panel 9 is a device that receives a user's operation of registering a landing call for the elevator 6 of the bank 5. The landing operating panel 9 may include a display panel such as a liquid crystal panel that displays the operation status of the elevator 6 of the bank 5 to a user at the landing, for example. The landing operating panel 9 may be provided with a notification device such as a speaker for notifying a user at a landing of the operation state of the elevator 6 of the bank 5. The landing operating panel 9 may be shared by the elevators 6 included in the same bank 5.

The evacuation support system 1 supports evacuation of users and the like of the facility 2 in cooperation with the elevators 6 of the elevator system 4. The evacuation support system 1 may be a system included in the elevator system 4. The evacuation support system 1 includes a plurality of fire detectors 10, a notification device 11, and a support device 12.

Each fire detector 10 corresponds to any bank 5 and any floor. Each fire detector 10 is provided at the corresponding floor in the landing of the corresponding bank 5. Each fire detector 10 is a device that detects a fire of the corresponding bank 5 at the corresponding floor. The fire detector 10 detects a fire by, for example, heat or smoke generated by the fire.

The notification device 11 is installed in a place such as a passageway in the facility 2. The notification device 11 is a device that notifies the evacuee when a fire occurs in the facility 2. The notification device 11 may be a speaker or the like that notifies the evacuee by voice, for example. Alternatively, the notification device 11 may be a display panel or the like that notifies the evacuee by displaying, for example. Alternatively, the notification device 11 may be a transmitter or the like that transmits information to a portable terminal carried by the evacuated person to notify. A plurality of notification devices 11 may be provided in the facility 2.

The assist apparatus 12 is an apparatus that performs information processing and the like relating to evacuation assistance by users and the like of the facility 2. The support apparatus 12 is, for example, a server apparatus or the like installed in the facility 2. The support device 12 includes an input unit 13, a map storage unit 14, a plan generation unit 15, a plan distribution unit 16, an arrival prediction unit 17, a plan update unit 18, and an evacuation control unit 19.

The input unit 13 is a part that acquires information on the detection status of a fire by each fire detector 10. The input unit 13 is connected to each of the fire detectors 10 so as to receive a detection signal or the like when the fire detector 10 detects a fire.

The map storage unit 14 is a part that stores map information of the facility 2. The map information of the facility 2 includes, for example, configuration information of a plurality of banks 5. The arrangement information of the banks 5 includes information of the path of movement between the respective banks 5 and the like. The configuration information of the bank 5 includes information of the bank 5 adjacent to each other among the plurality of banks 5.

The plan generating unit 15 is a part that generates an evacuation plan when a fire breaks out in the facility 2. The evacuation plan includes, for example, an evacuation route and an evacuation schedule. The evacuation route is a route from the rescue floor where the evacuee is located to the evacuation floor. In the evacuation route, an arbitrary bank 5 is used. The refuge schedule includes, for example, refuge completion predicted times for each bank 5 utilized. The evacuation schedule is calculated from, for example, the number of the evacuees, the transportation capacity of the evacuees for each evacuation route, and the like. The number of evacuees may be a predicted value based on, for example, the number of users who are staying at the rescue floor in a normal situation. For example, when a fire is detected by any of the fire detectors 10, the plan generating unit 15 determines that a fire has occurred in the facility 2, and generates an evacuation plan.

The plan delivery unit 16 is a part that delivers the evacuation plan generated by the plan generation unit 15. The plan issuing unit 16 issues an evacuation plan to the notification device 11, for example, to notify the evacuees of the evacuation plan. The evacuation plan notified to the evacuees may be part of information of an evacuation plan such as an evacuation route.

The arrival prediction unit 17 is a unit that predicts the arrival time of the fire for each bank 5. The arrival prediction unit 17 may not predict the arrival time for the bank 5 where the fire has arrived, for example. The arrival prediction unit 17 includes a speed calculation unit 20 and a time calculation unit 21. The speed calculation unit 20 is a part that calculates the speed of the fire from the detection situation of the fire by the plurality of fire detectors 10. The time calculation unit 21 is a unit that calculates the predicted time at which the fire will reach each bank 5, based on the fire propagation speed calculated by the speed calculation unit 20. The arrival prediction unit 17 predicts the arrival time of the fire, for example, as described below.

When a fire is first detected by any of the fire detectors 10, the speed calculation unit 20 monitors the detection of a fire by another fire detector 10. Here, the fire detector 10 that initially detects a fire is an example of the 1 st fire detector. The bank 5 corresponding to the 1 st fire detector is the 1 st bank. The time when the 1 st fire detector detects a fire is the 1 st time. The speed calculation unit 20 sets, for example, a fire detector 10 adjacent to the fire detector 10 that first detected the fire as a monitoring target. Alternatively, the speed calculation unit 20 may set the fire detector 10 to be monitored, the fire detector 10 being within a predetermined distance from the fire detector 10 that first detected the fire. Alternatively, the speed calculation unit 20 may set all the fire detectors 10 other than the fire detector 10 that first detected the fire as the monitoring target. The speed calculation unit 20 selects the fire detector 10 to be monitored, for example, based on the map information stored in the map storage unit 14.

Then, when the fire detector 10 to be monitored detects a fire, the speed calculation unit 20 calculates the speed of the fire. Here, the fire detector 10 that detects a fire after the fire detector 10 that initially detects a fire is an example of the 2 nd fire detector. The bank 5 to which the 2 nd fire detector corresponds is the 2 nd bank. The timing at which the 2 nd fire detector detects a fire is the 2 nd timing. The speed calculation unit 20 calculates the time from the 1 st time to the 2 nd time. The speed calculation unit 20 calculates the distance and direction from the 1 st bank to the 2 nd bank, for example, based on the map information stored in the map storage unit 14. The speed calculation unit 20 calculates the speed of the fire from the calculated distance to time ratio.

Here, the speed calculation unit 20 may calculate the speed of the fire to be a uniform speed. Alternatively, the speed calculation unit 20 may calculate the speed of the fire as an unequal speed. For example, in the bank 5 whose distance from the 1 st bank is shorter than the distance from the 1 st bank to the 2 nd bank, a fire may not be detected at the 2 nd time. In this case, the speed calculation unit 20 may calculate the speed of the fire in the direction from the 1 st bank toward the bank 5 where the fire has not been detected to be slower than the speed of the fire in the direction from the 1 st bank toward the 2 nd bank. In addition, there may be a case where 3 or more fire detectors 10 sequentially detect a fire. In this case, the speed calculation unit 20 may calculate the speed of the fire in the direction from the bank 5 corresponding to the fire detector 10 that first detected the fire toward the other banks 5, so as to vary from bank 5 to bank 5 according to the time at which the fire was detected. The speed calculation unit 20 may calculate the speed of the fire from the bank 5 corresponding to the fire detector 10 that first detected the fire to the direction in which the other bank 5 does not exist by interpolating the speed of the fire calculated in the direction in which the other bank 5 is located.

The time calculation unit 21 calculates the predicted time at which the fire reaches each bank 5 based on the rate of progression of the fire calculated by the speed calculation unit 20. The time calculation unit 21 calculates the distance and direction from the bank 5 in which the fire has been detected to the other banks 5, based on the map information stored in the map storage unit 14, for example. The time calculation unit 21 calculates the predicted time at which the fire reaches the other bank 5 based on the speed of progress calculated in the direction by the speed calculation unit 20 and the distance. The arrival prediction unit 17 predicts the arrival time of the fire based on the calculation result of the time calculation unit 21. For example, when a fire is detected in a plurality of banks 5, the time calculation unit 21 may calculate a plurality of arrival times for at least one bank 5. In this case, the arrival predicting unit 17 may predict the earliest time among the plurality of calculated arrival times as the arrival time of the fire.

The plan updating unit 18 is a part that causes the plan generating unit 15 to update the evacuation plan based on the arrival time of the fire predicted by the arrival predicting unit 17. The plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan, for example, based on the time from the current time to the time of arrival of the fire, which is predicted for each bank 5. For example, when the time from the current time to the time at which the fire reaches the predicted time in any bank 5 is shorter than a preset threshold value, the plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan using that bank 5. Alternatively, the plan updating unit 18 may update the evacuation plan so as to preferentially use the bank 5 having a long time from the current time to the predicted arrival time of the fire.

The evacuation control unit 19 is a part that outputs a control signal to the elevator 6 and the like included in each bank 5 based on the evacuation plan generated by the route generation unit. The control signal output by the evacuation control section 19 is, for example, a control signal for evacuation operation transmitted to the control panel 8 of each elevator 6. The control signal for the evacuation operation includes, for example, specification of an operation range in which the reciprocating operation is performed during the evacuation operation. The evacuation operation is, for example, an operation of reciprocating between a rescue floor and a retreat floor. The evacuation control section 19 may output a control signal for notifying the evacuees by display, notification, or the like to the landing operating panel 9 provided in each bank 5.

Next, an example of generating and updating the evacuation plan will be described with reference to fig. 2 to 4.

Fig. 2 is a plan view showing an example of a facility 2 to which the evacuation support system 1 according to embodiment 1 is applied.

Fig. 3 and 4 are diagrams showing examples of evacuation plans in the evacuation support system 1.

As shown in fig. 2, the facility 2 of this example includes two buildings 3, a and B. A building 3 of 7 stories with 1 story as a lobby story. In a, the lobby floor is set as the evacuation floor. B is a 7-story building 3 with 1 story as a lobby floor. In the B-hall, the lobby floor is set as the evacuation floor. A and B are connected in a manner that can be accessed through the vestibule 22. The corridors 22 connect the 4 levels of the a and the 4 levels of the B. The vestibule 22 is an example of a connection channel. The 4 floors of a and the 4 floors of B communicating with the connecting passage are examples of connecting floors, respectively. The connection floor is a floor different from the evacuation floor.

In lane a, bank 5b, bank 5c, bank 5d, bank 5e, bank 5f, bank 5g, bank 5h, bank 5i, and bank 5j are provided. A ladder group 5k and a ladder group 5l are provided in the B frame. For example, in lane a, bank 5c is adjacent to

banks

5a and 5 e. Since a wall is provided between the bank 5c and the bank 5d, the bank 5c is not adjacent to the bank 5 d. In addition, bank 5e is adjacent to

banks

5c and 5 g. Since no wall is provided between

banks

5e and 5f, bank 5e is also adjacent to bank 5 f. For example, when the section between the bank 5g and the bank 5h is not a wall but an atrium (け is removed き), the bank 5g may be treated as a bank adjacent to the bank 5 h. Alternatively, the bank 5g may be disposed as a bank adjacent to the bank 5h, for example, in a case where the wall between the bank 5g and the bank 5h is a simple wall having no sufficient fire-proof performance to prevent the progress of a fire. Here, when the individual banks from the bank 5a to the bank 5l are not specified, only the bank 5 may be referred to. In this example, each bank 5 includes one elevator 6.

Fig. 3 shows an example of an evacuation route generated when a fire is detected by the fire detector 10 corresponding to the bank 5c of 3 floors. In fig. 3, a schematic view of the facility 2 is shown as viewed from the south side.

The plan generating unit 15 generates an evacuation route not using the bank 5c, for example, in the evacuation plan. The plan generating unit 15 generates an evacuation route for evacuating an evacuee positioned between the

banks

5a and 5c using the

bank

5a or 5b, for example. The plan generating unit 15 generates an evacuation route for evacuating an evacuee positioned between the bank 5c and the bank 5e by using the bank 5e or the bank 5f, for example.

The evacuation control unit 19 outputs control signals to the elevators 6 included in the respective banks 5 in accordance with the generated evacuation plan. The control signal outputted at this time is used for, for example, performing a reciprocating operation between the rescue floor and the evacuation floor. The evacuation control unit 19 outputs a control signal for notifying the generated evacuation plan to the evacuees to the landing operation panel 9 provided in each bank 5. Each landing operating panel 9 notifies information such as an evacuation route to an evacuated person in accordance with a control signal from the evacuation control section 19.

The plan delivery unit 16 delivers the generated evacuation plan to the notification device 11. Upon receiving the distribution, the notification device 11 notifies the evacuee of information such as an evacuation route.

The refugees who have received the notification of the evacuation plan through the landing operation panel 9, the notification device 11, or the like perform evacuation from the rescue floor to the evacuation floor using the bank 5 specified in accordance with the evacuation plan.

Fig. 4 shows an example of an evacuation route updated according to the progress of a fire. A schematic view of the installation 2 from the south side is shown in fig. 4.

In this example, an example of an updated evacuation route when a fire is detected by the fire detector 10 corresponding to the bank 5e of 3 floors is shown.

When the fire detector 10 corresponding to the bank 5e detects a fire, the arrival prediction unit 17 predicts the arrival time of the fire for each bank 5.

The plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan based on the fire arrival time predicted by the arrival predicting unit 17. The plan updating unit 18 determines whether or not the time from the current time to the time when the fire reaches the predicted time is shorter than the 1 st threshold value, for example, for the bank 5 used in the evacuation plan. The 1 st threshold is a threshold set in advance with respect to time. For the bank 5 determined to have a time until the fire arrives shorter than the 1 st threshold, the plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan so that the evacuees evacuate via the other buildings 3 in the facility 2. In this example, it is determined that the time until the fire reaches bank 5g is shorter than threshold 1. Further, the plan updating unit 18 determines whether or not the time from the current time to the time at which the fire reaches the predicted time is shorter than the 2 nd threshold value, for example, for the bank 5 used in the evacuation plan. The 2 nd threshold is a threshold set in advance with respect to time. In this example, the 2 nd threshold is a time shorter than the 1 st threshold. For the bank 5 determined to have a time to fire arrival shorter than the 2 nd threshold, the plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan so as not to use the bank 5. In this example, it is determined that the time until the fire reaches bank 5f is shorter than the 2 nd threshold value.

The plan generating unit 15 updates the evacuation plan to an evacuation plan not using the bank 5f, for example, in the evacuation plan. At this time, the plan generating unit 15 allocates the refugees, which were allocated to the evacuation route as refugees who evacuated along the evacuation route, to other evacuation routes. Further, the plan generating unit 15 updates the evacuation plan to, for example, the following evacuation plan: the evacuation route using the bank 5g of A is set as an evacuation route for evacuating the evacuees through the bank B. The evacuation route includes, for example, a movement to 4 floors as a connected floor through the bank 5g of a, a movement from a to B floors through the corridor 22, and a movement to 1 floor as a retreat floor through the bank 5k of B floors. At this time, a is an example of the 1 st building. In addition, B is an example of the 2 nd building.

The evacuation control unit 19 outputs a control signal to the elevator 6 included in each bank 5 according to the updated evacuation plan. The evacuation control unit 19 outputs a control signal for stopping the operation of the elevator 6 included in the bank 5f, for example. The evacuation control unit 19 outputs a control signal for switching to the reciprocating operation between the rescue floor and the connection floor to the elevator 6 included in the bank 5f, for example. The evacuation control unit 19 also outputs a control signal for notifying the updated evacuation plan to the evacuees to the landing operation panel 9 provided in each bank 5. Each of the landing operating panels 9 notifies the refugees of information such as updated evacuation plans and updated evacuation routes, based on a control signal from the evacuation control section 19. At this time, each landing operating panel 9 may notify the user of the arrival time of the fire predicted by the arrival prediction unit 17 for the bank 5 in which the landing operating panel 9 is installed.

The plan delivery unit 16 delivers the updated evacuation plan to the notification device 11. The notification device 11 that has received the delivery notifies the evacuee of information such as the updated evacuation plan and the updated evacuation route.

The evacuees who have received the updated evacuation plan notification by the hall operating panel 9, the notification device 11, or the like perform evacuation from the rescue floor to the evacuation floor using the bank 5 specified in accordance with the evacuation plan.

When the fire detector 10 corresponding to another bank 5 detects a fire, the arrival prediction unit 17 updates the prediction of the arrival time of the fire for each bank 5. In this case, one of two fire detectors 10 among the plurality of fire detectors 10 that have detected a fire, which has detected the fire first, is the 1 st fire detector. Further, the second fire detector is an example of the second fire detector. The 1 st fire detector may not be the fire detector 10 that initially detected the fire. The plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan based on the updated predicted value of the arrival time. The evacuation control unit 19 outputs a control signal according to the updated evacuation plan. The plan delivery unit 16 delivers the updated evacuation plan to the notification device 11.

Next, an operation example of the evacuation support system 1 will be described with reference to fig. 5 and 6.

Fig. 5 and 6 are flowcharts showing an operation example of the evacuation support system 1 according to embodiment 1.

In step S01 of fig. 5, any fire detector 10 detects a fire. Thereafter, in step S02, the speed calculation unit 20 selects the fire detector 10 to be monitored, based on the arrangement of the fire detector 10 that has detected the fire and the other fire detectors 10. Thereafter, in step S03, the plan generating unit 15 generates an evacuation plan. Thereafter, in step S04, the route distribution unit distributes the evacuation plan so that the notification device 11 can notify the evacuees. The evacuation control section 19 outputs a control signal to the landing operation panel 9 and the like to notify the evacuees. The evacuation control unit 19 outputs control signals to the elevators 6 in accordance with the evacuation plan. Thereafter, the operation of the evacuation support system 1 proceeds to step S05.

In step S05, the speed calculation unit 20 determines whether or not the fire detector 10 to be monitored detects a fire. If the determination result is "no", the operation of the evacuation support system 1 proceeds to step S06. If the determination result is yes, the operation of the evacuation support system 1 proceeds to step S07.

In step S06, the support apparatus 12 determines whether evacuation of the evacuee has been completed. The support device 12 determines that evacuation is complete, for example, when an input of evacuation completion is received from a terminal device connected to the support device 12, such as a manager of the facility 2 or a disaster countermeasure headquarters provided for fire. If the determination result is yes, the operation of the evacuation support system 1 is ended. If the determination result is "no", the operation of the evacuation support system 1 proceeds to step S05.

In step S07, the speed calculation unit 20 calculates the speed of the fire. Thereafter, in step S08, the time calculation unit 21 calculates the estimated time at which the fire reaches each bank 5. The arrival prediction unit 17 predicts the arrival time of the fire based on the calculation result of the time calculation unit 21. Thereafter, in step S09, the plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan based on the prediction of the arrival time by the arrival predicting unit 17. Thereafter, in step S10, the route delivery unit delivers the updated evacuation plan so that the notification device 11 can notify the evacuees. The evacuation control section 19 outputs a control signal to the landing operation panel 9 and the like to notify the evacuees. The evacuation control unit 19 outputs control signals to the elevators 6 in accordance with the updated evacuation plan. Thereafter, the operation of the evacuation support system 1 proceeds to step S06.

Fig. 6 shows details of the processing related to the updating of the evacuation plan at step S09 in fig. 5.

In step S91 of fig. 6, the plan update unit 18 selects one bank 5 to be processed from the banks 5 in which the fire has not been detected. Thereafter, the operation of the evacuation support system 1 proceeds to step S92.

In step S92, the plan update unit 18 determines whether or not the time from the current time to the time when the fire reaches the bank 5 to be processed is shorter than the 1 st threshold. If the determination result is "no", the operation of the evacuation support system 1 proceeds to step S93. If the determination result is yes, the operation of the evacuation support system 1 proceeds to step S96.

In step S93, the plan updating unit 18 instructs the plan generating unit 15 to update the evacuation plan so that the elevators 6 included in the bank 5 to be processed reciprocate between the rescue floor and the evacuation floor. Thereafter, the operation of the evacuation support system 1 proceeds to step S94.

In step S94, the plan updating unit 18 determines whether or not all of the banks 5 in which the fire has not been detected have been selected as the banks 5 to be processed. If the determination result is "no", the operation of the evacuation support system 1 proceeds to step S91. If the determination result is yes, the operation of the evacuation support system 1 proceeds to step S95.

In step S95, the plan generator 15 regenerates the evacuation plan in accordance with the instruction from the plan updating unit 18. Thereafter, the operation of the evacuation support system 1 related to the update process of the evacuation plan is ended.

In step S96, the plan update unit 18 determines whether or not the time from the current time to the time when the fire reaches the bank 5 to be processed is shorter than the 2 nd threshold. If the determination result is "no", the operation of the evacuation support system 1 proceeds to step S97. If the determination result is yes, the operation of the evacuation support system 1 proceeds to step S98.

In step S97, the plan updating unit 18 instructs the plan generating unit 15 to update the evacuation plan so that the elevators 6 included in the bank 5 to be processed reciprocate between the rescue floor and the connection floor. Here, when a plurality of connected floors are provided in the facility 2, the plan updating unit 18 instructs the plan generating unit 15 to update the evacuation plan so as to reciprocate between the rescue floor and the nearest connected floor of the rescue floors, for example. Thereafter, the operation of the evacuation support system proceeds to step S94.

In step S98, the plan updating unit 18 instructs the plan generating unit 15 to update the evacuation plan so that the operation of the elevator 6 included in the bank 5 to be processed is stopped. Thereafter, the operation of the evacuation support system proceeds to step S94.

As described above, the evacuation support system 1 according to embodiment 1 includes the plurality of fire detectors 10, the plan generating unit 15, the arrival predicting unit 17, and the plan updating unit 18. Each fire detector 10 is provided at the facility 2. Each fire detector 10 detects a fire in the corresponding bank 5. When a fire breaks out in the facility 2, the plan generating unit 15 generates an evacuation plan from the rescue floor to the evacuation floor using any of the banks 5. When two fire detectors 10 sequentially detect a fire, the arrival prediction unit 17 predicts the arrival time of the fire for at least one bank 5 based on the arrangement of the banks 5 corresponding to the two fire detectors 10 and the time difference between the two fire detectors 10 detecting the fire. The plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan based on the arrival time predicted by the arrival predicting unit 17.

With this configuration, the evacuation plan is updated as needed in accordance with a change in the actually detected fire situation. The fire occurring in the facility 2 progresses under the influence of the structure of the building 3 of the facility 2, weather conditions, and other conditions, and therefore, it is difficult to predict in advance. On the other hand, since the evacuation plan in the evacuation support system 1 is updated in accordance with the situation of the fire that is actually detected, the evacuated persons can evacuate in accordance with the evacuation plan corresponding to the progress of the fire.

The evacuation support system 1 further includes an evacuation control unit 19. The evacuation control unit 19 outputs a control signal for evacuation operation to the elevators 6 included in each bank 5 in accordance with the evacuation plan generated by the plan generation unit 15.

According to such a configuration, the elevators 6 in the facility 2 are operated according to the generated and updated evacuation plan. Therefore, the evacuation efficiency by the elevator 6 can be further improved. Further, since the elevators 6 of the respective banks 5 are operated according to the evacuation plan of the facility 2, the plan generating unit 15 can generate an evacuation plan in which the plurality of banks 5 are coordinated. This can further improve the efficiency of evacuation of the evacuees from the facility 2.

Further, the facility 2 may include a plurality of buildings 3, and the plurality of buildings 3 may be connected to each other so as to be able to pass through a corridor 22 or the like at a connection floor. In this case, there is a possibility that: the time until the arrival time predicted by the arrival prediction unit 17 is shorter than the preset 1 st threshold value for the bank 5 installed in any building 3. At this time, the evacuation control unit 19 outputs a control signal for switching to the reciprocating operation between the rescue floor and the connection floor to the elevator 6 included in the bank 5.

With such a configuration, the time for the reciprocating operation of the elevator 6 can be shortened in the bank 5 in which the time until the fire arrives is short. Since the number of the evacuees that can be transported per unit time is increased, evacuation of a place on a rescue floor where the time from the arrival of a fire is short can be performed more quickly. The evacuees who have moved from the rescue floor to the connection floor by the elevator 6 can move to another building 3 through the corridor 22 or the like. The refugees can refuge in accordance with a refuge plan using the elevator 6 of the other building 3. This can further improve the efficiency of evacuation of the evacuees from the facility 2.

When the time to the arrival time predicted by the arrival prediction unit 17 for any bank 5 is shorter than the 2 nd threshold value set in advance, the evacuation control unit 19 outputs a control signal for stopping the operation to the elevator 6 included in the bank 5.

According to such a configuration, since the operation of the elevator 6 is stopped in the bank 5 in which the time until the fire arrives is short, it is prevented that the fire arrives at the bank 5 while the evacuee is using the elevator 6. This enables the refugees from the facility 2 to be more reliably refueled.

When the plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan, the evacuation control unit 19 outputs a control signal for notifying the update of the evacuation plan to the elevators 6 included in the respective banks 5.

The evacuation support system 1 further includes a notification device 11. The notification device 11 is provided in the facility 2. When the plan updating unit 18 causes the plan generating unit 15 to update the evacuation plan, the notification device 11 notifies the evacuee of the update of the evacuation plan.

According to such a configuration, it is easy for an refuge person who performs evacuation in accordance with the evacuation plan to notice the update of the evacuation plan. In particular, the update of the evacuation plan is notified at the landing operating panel 9 of the elevator 6 or the like, so that the evacuee can grasp the update of the evacuation plan before using the elevator 6. This makes it less likely that the refugee who is out of compliance with the evacuation plan will move due to old information, information errors, or the like.

Next, an example of the hardware configuration of the evacuation support system 1 will be described with reference to fig. 7.

Fig. 7 is a hardware configuration diagram of a main part of the evacuation support system 1 according to embodiment 1.

Each function of the evacuation support system 1 can be realized by a processing circuit. The processing circuit is provided with at least one processor 100a and at least one memory 100 b. The processing circuit may include the processor 100a and the memory 100b, or may include at least one dedicated hardware 200 instead of these.

When the processing circuit includes the processor 100a and the memory 100b, each function of the evacuation support system 1 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 100 b. The processor 100a reads out and executes the program stored in the memory 100b to realize each function of the evacuation support system 1.

The processor 100a is also called a CPU (Central Processing Unit), a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The Memory 100b is composed of a nonvolatile or volatile semiconductor Memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), or the like.

When the processing Circuit includes the dedicated hardware 200, the processing Circuit is realized by, for example, a single Circuit, a composite Circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

Each function of the evacuation support system 1 can be realized by a processing circuit. Alternatively, the functions of the evacuation support system 1 may be realized by the processing circuit in a lump. Each function of the evacuation support system 1 may be implemented partially by dedicated hardware 200 and partially by software or firmware. In this way, the processing circuit realizes each function of the evacuation support system 1 by dedicated hardware 200, software, firmware, or a combination thereof.
