[0003] [Patent Document 1] JP 2013-193863 A Summary of the Invention [Problem to be solved by the invention]

[0004] In an elevator system such as that shown in Patent Document 1, when a disaster occurs, an autonomous mobile object such as a robot is notified that the elevator has switched from normal operation to emergency operation, and the autonomous mobile object selects whether to continue riding or to dismount. However, no consideration is given to human evacuation using the elevator when a disaster occurs, so there is a risk that evacuation by humans using the elevator will be affected if the autonomous mobile object selects to continue riding during emergency operation due to a disaster. Conversely, if the autonomous mobile object selects to dismount in a situation where there is a relatively low need for humans to use the elevator to evacuate when a disaster occurs, there is a possibility that the autonomous mobile object will be damaged by the disaster.

[0005] The present disclosure has been made to solve such problems. Its purpose is to provide an elevator system, a control method and a program for an elevator system, which enable autonomous mobile objects in a building to use the elevator while suppressing the impact on the use of the elevator by people in the building when a disaster occurs or in a situation where a disaster is expected to occur, and which can ensure the evacuation and protection of people while also evacuating and protecting the autonomous mobile objects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The elevator system, elevator system control method, and program according to the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are given the same reference numerals, and duplicated descriptions are appropriately simplified or omitted. In the following description, for convenience, the positional relationship of each structure may be expressed based on the illustrated state. Note that the present disclosure is not limited to the following embodiments, and the embodiments may be freely combined, any component of each embodiment may be modified, or any component of each embodiment may be omitted, within the scope of the present disclosure.

[0012] Embodiment 1 A first embodiment of the present disclosure will be described with reference to Fig. 1 to Fig. 7. Fig. 1 is a block diagram showing a configuration of an elevator system. Fig. 2 is a diagram showing evacuation of an autonomous moving body in the elevator system using an elevator. Figs. 3 to 6 are flow diagrams showing an example of the operation of the elevator system. Fig. 7 is a diagram showing an example of a configuration for realizing functions of a control device and the like of the elevator system.

[0013] The elevator system according to this embodiment includes a control device 100, as shown in FIG. 1. The control device 100 is a device that controls the overall operation of the elevator according to this system. In the configuration example shown in the figure, the elevator according to this system has two cars 10. However, the number of cars 10 in the elevator system according to the present disclosure is not limited to two. The number of cars 10 in the elevator system according to the present disclosure may be three or more. In addition, the elevator system according to the present disclosure is particularly suitable for the case where the number of cars 10 is two or more, but the number of cars 10 may be one.

[0014] In the building in which the elevator is installed, an autonomous mobile body 20 is operated. The autonomous mobile body 20 is, for example, a mobile robot, and can move autonomously. Each autonomous mobile body 20 can communicate with a mobile body management server 200. The mobile body management server 200 controls the operation of each autonomous mobile body 20 and manages the state of each autonomous mobile body 20. The control device 100 and the mobile body management server 200 are connected to be able to communicate in both directions. In the elevator system according to this embodiment, information can be exchanged between the control device 100 and the mobile body management server 200, and the operation of the elevator and the operation of the autonomous mobile body 20 can be coordinated.

[0015] The control device 100 includes a disaster information acquisition unit 111. The disaster information acquisition unit 111 acquires information on the occurrence of a disaster in a building in which the elevator is installed. The information on the occurrence of a disaster may be actual information on the occurrence of a disaster, may be predicted information on the occurrence of a disaster, or may include both of these. The actual information on the occurrence of a disaster is information on a disaster that has actually already occurred at the present time. The predicted information on the occurrence of a disaster is information on a disaster that may occur in the future. The information on the occurrence of a disaster includes the type of the disaster and the extent of the disaster. If the information on the occurrence of a disaster is actual information on the occurrence of a disaster, the information on the occurrence of a disaster further includes the time when the disaster occurred (disaster occurrence time), and if the information on the occurrence of a disaster is predicted information on the occurrence of a disaster, the information on the occurrence of a disaster further includes the time when the disaster is predicted (disaster occurrence time).

[0016] In the illustrated configuration example, the disaster information acquisition unit 111 acquires information on the occurrence of a disaster in a building in which the elevator is installed from an external server 300. The external server 300 is a server that provides information on the occurrence of a disaster. The external server 300 provides, for example, any one or more of meteorological information, flood information, earthquake information, tsunami information, landslide information, and fire information as information on the occurrence of a disaster.

[0017] Examples of meteorological information related to the occurrence of a disaster include actual and predicted precipitation values ​​in the area where the building is located, heavy rain advisories and heavy rain warnings (flooding) for the area where the building is located, special heavy rain warnings, information on record-breaking short-term heavy rain, meteorological information related to significant heavy rain, etc. In this case, the type of disaster in the information related to the occurrence of a disaster is flooding. The extent of the disaster is represented, for example, by the amount of precipitation indicated by this information. The time of occurrence of the disaster (or the time when it is expected to occur) is represented, for example, by the time when a certain amount of precipitation or more is actually observed, or the time when a certain amount of precipitation or more is expected.

[0018] Examples of flood information that is information regarding the occurrence of a disaster include flood advisories and flood warnings for the area where the building is located, actual and predicted values ​​of river water levels in the area where the building is located, flood forecasts (flood advisory information, flood warning information, flood risk information, flood occurrence information) for the river basin and section in the area where the building is located, and flood prevention warnings. In this case, too, the type of disaster in the information regarding the occurrence of a disaster is flood damage. The extent of the disaster is represented, for example, by the amount of precipitation or river water level indicated in the information. The time of occurrence of the disaster (or the time of expected occurrence) is represented, for example, by the time when the water level exceeding the flood danger water level was actually observed, or the time when the water level is expected to exceed the flood danger water level.

[0019] Examples of earthquake information that is information regarding the occurrence of a disaster include earthquake sensor measurement values ​​in the area where the building is located, emergency earthquake warnings, seismic intensity warnings, and information on the epicenter and seismic intensity for the area where the building is located. In this case, the type of disaster in the information regarding the occurrence of a disaster is an earthquake. The extent of the disaster is indicated by the seismic intensity, etc. indicated in this information. The time of occurrence of the disaster is indicated by the time of occurrence of the earthquake, etc. indicated in this information.

[0020] Examples of tsunami information that is information regarding the occurrence of a disaster include a major tsunami warning, tsunami warning, and tsunami advisory that are targeted at the area where the building is located. In this case, the type of disaster in the information regarding the occurrence of a disaster is, for example, flooding caused by a tsunami. The extent of the disaster is indicated by the height of the tsunami, etc., indicated in this information. The time of occurrence of the disaster (or the time it is expected to occur) is indicated by the arrival time or expected arrival time of the tsunami, etc., indicated in this information.

[0021] Examples of landslide information, which is information regarding the occurrence of a disaster, include heavy rain advisories and heavy rain warnings (landslides) for the area where the building is located, and landslide alert information. In this case, the type of disaster in the information regarding the occurrence of a disaster is landslide. If a landslide such as a mudslide, landslide, or cliff collapse occurs, the damage to the building is expected to be severe, so the degree of the disaster in the case of a landslide is basically considered to be large. In addition, the time when the disaster is expected to occur is expressed, for example, as the time period when the risk of landslides is highest.

[0022] An example of fire information that is information regarding the occurrence of a disaster is the detection result of a fire detector installed in the building or in buildings adjacent to the building. In this case, the type of disaster in the information regarding the occurrence of a disaster is fire. The extent of the disaster is represented, for example, by the number of detectors that detected the occurrence of the fire. The time when the disaster occurred is represented, for example, by the time when a detector first detected the occurrence of the fire.

[0023] The control device 100 further includes an evacuation urgency determination unit 112. The evacuation urgency determination unit 112 determines the urgency of evacuation of people in a building in the event of a disaster (hereinafter, referred to as "evacuation urgency" in this disclosure) based on information on the occurrence of a disaster acquired by the disaster information acquisition unit 111. As described above, the information on the occurrence of a disaster includes the type of disaster, the extent of the disaster, and the time of disaster occurrence (or the expected time of disaster occurrence). The evacuation urgency determination unit 112 determines the evacuation urgency based on this information. In the example described here, it is assumed that there are two levels of evacuation urgency, "high" and "low". However, the evacuation urgency is not limited to two levels. For example, the evacuation urgency may be three levels, "high", "medium", and "low", or may be four or more levels.

[0024] Several examples of the determination of the evacuation urgency by the evacuation urgency determination unit 112 will be described. For example, when the type of disaster is a fire, the evacuation urgency determination unit 112 determines that the evacuation urgency is "high". When the type of disaster is flood damage and the disaster has already occurred, the evacuation urgency determination unit 112 determines that the evacuation urgency is "high". On the other hand, when the type of disaster is flood damage and the disaster has not yet occurred but is expected to occur in the future, the evacuation urgency determination unit 112 determines whether the evacuation urgency is "high" or "low" depending on the time from the current time to the expected occurrence time. That is, when the time from the current time to the expected occurrence time is equal to or longer than a preset reference time, the evacuation urgency determination unit 112 determines that the evacuation urgency is "low". On the other hand, when the time from the current time to the expected occurrence time is less than the reference time, the evacuation urgency determination unit 112 determines that the evacuation urgency is "high".

[0025] For other types of disasters, the evacuation urgency determination unit 112 determines the evacuation urgency of the disaster according to the type of disaster, the level of the disaster, whether the disaster has already occurred, and if the disaster has not actually occurred, the time from the current time to the expected time of occurrence. In this case, generally, the greater the level of the disaster, the higher the evacuation urgency of the disaster. Also, if the disaster has already occurred, the higher the evacuation urgency of the disaster. And, if the disaster has not actually occurred, the shorter the time from the current time to the expected time of occurrence, the higher the evacuation urgency of the disaster. For another example, points corresponding to the type of disaster, the level of the disaster, whether the disaster has already occurred, and if the disaster has not actually occurred, the time from the current time to the expected time of occurrence may be set in advance, and the evacuation urgency determination unit 112 may determine the evacuation urgency of the disaster according to the total value of these points for the current disaster.

[0026] The control device 100 further includes an evacuation plan unit 113. The evacuation plan unit 113 formulates an evacuation plan based on the urgency of evacuation of people in the building determined by the evacuation urgency determination unit 112. The evacuation plan formulated by the evacuation plan unit 113 includes at least a first number. The first number is the number of elevator cars 10 used for evacuation of the autonomous moving bodies 20 in the building in the event of the disaster. The evacuation plan unit 113 determines the first number according to the evacuation urgency determined by the evacuation urgency determination unit 112, i.e., the urgency of evacuation of people in the building.

[0027] For example, the higher the evacuation urgency determined by the evacuation urgency determination unit 112, the smaller the first number of vehicles, and conversely, the lower the evacuation urgency, the larger the first number of vehicles. As described above, in the configuration example described here, the evacuation urgency has two stages, "high" and "low". Therefore, when the evacuation urgency is "high", the evacuation planning unit 113 determines the first number to be a preset number, and when the evacuation urgency is "low", the evacuation planning unit 113 determines the first number to be a number smaller than when the evacuation urgency is "high".

[0028] As described above, the elevator system according to the present disclosure is particularly suitable for a case where the number of cars 10 is two or more, but the number of cars 10 may be one. When the number of cars 10 is one, the evacuation planning unit 113 determines whether the first number is one or zero, in accordance with the evacuation urgency determined by the evacuation urgency determination unit 112, that is, whether or not to use an elevator for evacuation of the autonomous moving body 20 in the building in the event of the disaster.

[0029] The evacuation plan formulated by the evacuation planning unit 113 includes the first number of vehicles as well as evacuation floors, etc. When the type of disaster is flooding, the evacuation planning unit 113 determines the evacuation floor to be an upper floor of the building. When the type of disaster is fire or the like other than flooding, the evacuation planning unit 113 determines floors other than the floor where the disaster is occurring as evacuation floors. In addition, floors where safety can be ensured may be registered in advance as evacuation floors.

[0030] The evacuation planning unit 113 acquires information on the state of the autonomous moving bodies 20, i.e., the number of autonomous moving bodies 20 in the building, their respective current positions, whether the autonomous moving bodies 20 have elevator boarding capability, and the like, from the moving body management server 200. The evacuation planning unit 113 also acquires information on the operation state of the elevator car 10 in the building from the elevator control unit 120. Then, the evacuation planning unit 113 formulates an evacuation plan for people and the autonomous moving bodies 20 in the building using the determined first number and evacuation floor, the state of the autonomous moving bodies 20, the operation state of the car 10, and the like.

[0031] The elevator control unit 120 controls the elevator car 10 based on the evacuation plan formulated by the evacuation plan unit 113. Therefore, the elevator control unit 120 controls the car 10 so that the first number of cars 10 determined by the evacuation plan unit 113 is used for the evacuation of the autonomous moving body 20 in the building in the disaster. That is, the elevator control unit 120 dispatches the first number of cars 10 for the evacuation of the autonomous moving body 20. In addition, the moving body management server 200 controls the operation of the autonomous moving body 20 so as to evacuate the autonomous moving body 20 based on the evacuation plan formulated by the evacuation plan unit 113. That is, the autonomous moving body 20 is caused to board the first number of cars 10 dispatched by the elevator control unit 120, and the autonomous moving body 20 is evacuated (FIG. 2).

[0032] According to the elevator system configured as described above, in the event of a disaster or in a situation where a disaster is expected to occur, the number of cars 10 to be used for the evacuation of the autonomous mobile bodies 20 can be determined according to the urgency of human evacuation in the event of the disaster, thereby enabling the autonomous mobile bodies in the building to use the elevator (evacuation using the elevator) while suppressing the impact on the use of the elevator by people in the building (evacuation using the elevator). Therefore, the autonomous mobile bodies 20 can be evacuated and protected while ensuring the evacuation and protection of people.

[0033] Next, some modified examples of the method of determining the first number by the evacuation planning unit 113 will be described. First, in the first modified example, when the evacuation urgency is "high", the first number is determined according to the elevator utilization rate by people. In this first modified example, as shown in FIG. 1, the control device 100 further includes an elevator utilization rate acquisition unit 114. The elevator utilization rate acquisition unit 114 acquires the elevator utilization rate by people in the building. The elevator utilization rate by people is, for example, the proportion of time during a certain period of time that the elevator car 10 is in operation for people to use the elevator (board the car 10).

[0034] The elevator utilization rate acquisition unit 114 obtains the operating time of each car 10 due to human use, for example, using the running state of each car 10, the call registration status for each car 10, the load on each car 10, etc., and calculates the utilization rate of each car 10 by humans, i.e., the utilization rate of the elevator by humans. The elevator utilization rate acquisition unit 114 acquires from the elevator control unit 120 the running state of each car 10, the call registration status for each car 10, the load on each car 10, etc., which are necessary for calculating the utilization rate of the elevator by humans.

[0035] In this first modified example, when the evacuation urgency determined by the evacuation urgency determination unit 112 is "high", the evacuation planning unit 113 determines the first number of vehicles according to the elevator utilization rate by people acquired by the elevator utilization rate acquisition unit 114. Specifically, for example, when the evacuation urgency is "high", the evacuation planning unit 113 decreases the first number as the elevator utilization rate by people is higher, and increases the first number as the elevator utilization rate by people is lower. In this way, evacuation by people using the elevator is prioritized, while the autonomous moving body 20 can also be evacuated using the elevator.

[0036] Furthermore, for example, when the evacuation urgency determined by the evacuation urgency determination unit 112 is "high", the evacuation planning unit 113 may increase the first number stepwise from 0 by one at a time at regular intervals after the elevator utilization rate by people acquired by the elevator utilization rate acquisition unit 114 falls below a preset reference utilization rate. This reference utilization rate is set to, for example, a utilization rate value at which the evacuation of people in the building can be considered to be complete. That is, in this case, the evacuation planning unit 113 determines whether or not the evacuation of people in the building has been completed based on the elevator utilization rate by people.

[0037] Here, if this first modified example is generalized to a case where the evacuation urgency level is more than two levels, "high" and "low", the evacuation planning unit 113 determines the first number of vehicles according to the elevator utilization rate by people acquired by the elevator utilization rate acquisition unit 114 when the evacuation urgency level of people in the building is equal to or higher than a preset reference urgency level. In addition, when the evacuation urgency level of people in the building is equal to or higher than the above-mentioned reference urgency level, the evacuation planning unit 113 may increase the first number of vehicles in stages after the elevator utilization rate falls below the above-mentioned reference urgency level. Note that, when the evacuation urgency level has two levels, "high" and "low", the reference urgency level is set to "high". Thus, when the evacuation urgency level is "high", the evacuation urgency level is equal to or higher than the reference urgency level, and when the evacuation urgency level is "low", the evacuation urgency level is lower than the reference urgency level.

[0038] Next, a second modified example of the method of determining the first number by the evacuation planning unit 113 will be described. In this second modified example, when the evacuation urgency level is "high", the first number is determined according to the number of people remaining in the building. In this second modified example, as shown in FIG. 1, the control device 100 further includes a building number of people acquisition unit 115.

[0039] The control device 100 can communicate with the building system 400. The building system 400 is a building management system that manages the building, i.e., the building. The building system 400 includes, for example, an entrance / exit management system, a surveillance camera system, etc., and can grasp the number of people staying in the building, i.e., the building, through these systems. The building number of people acquisition unit 115 acquires the number of people remaining in the building from the building system 400.

[0040] In this second modified example, when the evacuation urgency determined by the evacuation urgency determination unit 112 is "high", the evacuation planning unit 113 determines the first number of vehicles according to the number of people remaining in the building acquired by the building population acquisition unit 115. Specifically, for example, when the evacuation urgency is "high", the evacuation planning unit 113 decreases the first number of vehicles as the number of people remaining in the building increases, and increases the first number of vehicles as the number of people remaining in the building decreases. In this way, evacuation by people using elevators is prioritized, while the autonomous moving bodies 20 can also be evacuated using elevators.

[0041] As another example, when the evacuation urgency determined by the evacuation urgency determination unit 112 is "high", the evacuation planning unit 113 may calculate the second number based on the number of people remaining in the building acquired by the building population acquisition unit 115. The second number is the number of elevator cars 10 required to evacuate the people remaining in the building by elevator without waiting time. In this case, the evacuation planning unit 113 calculates the first number by subtracting the calculated second number from the total number of elevator cars 10.

[0042] As in the first modified example described above, if the second modified example is generalized to a case where the degree of evacuation urgency is more than two levels, "high" and "low", then when the degree of evacuation urgency of people in the building is equal to or higher than a preset reference degree of urgency, the evacuation planning unit 113 determines the first number of cars in accordance with the number of people remaining in the building acquired by the building population acquisition unit 115. Furthermore, when the degree of evacuation urgency of people in the building is equal to or higher than the reference degree of urgency described above, the evacuation planning unit 113 may calculate a second number, which is the number of cars 10 required to evacuate the people remaining in the building by elevator without waiting, based on the number of people remaining in the building, and determine the number obtained by subtracting the second number from the total number of elevator cars 10 as the first number.

[0043] Next, a third modified example of the method of determining the first number by the evacuation planning unit 113 will be described. In this third modified example, when the evacuation urgency is "low", the first number is determined according to the grace period until the autonomous moving bodies 20 in the building are damaged by a disaster. As described above, the mobile body management server 200 manages the state of the autonomous moving bodies 20. In this third modified example, when the evacuation urgency is "low", the evacuation planning unit 113 acquires information on the state of the autonomous moving bodies 20, that is, the number of autonomous moving bodies 20 in the building and their respective current positions, from the mobile body management server 200. In addition, the evacuation planning unit 113 acquires information on the operation state of the elevator cars 10 in the building from the elevator control unit 120.

[0044] Then, the evacuation planning unit 113 estimates a grace period until the autonomous moving bodies 20 in the building are damaged by the disaster based on the operation information of the car 10, the state of the autonomous moving bodies 20, and information on the occurrence of the disaster acquired by the disaster information acquisition unit 111 (for example, the predicted time of the disaster occurrence). The evacuation planning unit 113 calculates the minimum number of cars 10 that can complete the evacuation of the autonomous moving bodies 20 in the building before the calculated grace period elapses, and determines the calculated number as the first number. In this way, the minimum number of cars 10 that can complete the evacuation of the autonomous moving bodies 20 within the grace period are used for the evacuation of the autonomous moving bodies 20, so that people can evacuate using the elevator while evacuating and protecting the autonomous moving bodies 20.

[0045] Here, if this third variant is generalized to cases where the evacuation urgency is more than two levels, "high" and "low," then when the urgency of evacuation of people in a building is less than a preset standard urgency, the evacuation planning unit 113 estimates the grace period until the autonomous moving bodies 20 in the building are damaged by a disaster, and determines as the first number the minimum number of autonomous moving bodies 20 in the building that can complete evacuation before the grace period has elapsed.

[0046] It is also possible to combine the above-mentioned first or second modified example with this third modified example. In this case, the standard urgency in the first or second modified example is a standard for determining whether the evacuation urgency is high, while the standard urgency in the third modified example is a standard for determining whether the evacuation urgency is low. Therefore, particularly when the evacuation urgency is three or more stages, the standard urgency in the first or second modified example may be different from the standard urgency in the third modified example.

[0047] Next, an example of the operation of the elevator system according to this embodiment will be described with reference to the flow diagrams of Figures 3 to 6. In these flow diagrams, "robot" refers to the autonomous mobile body 20, "robot evacuation vehicle" refers to the car 10 used for the evacuation of the autonomous mobile body 20, "number of robot evacuation vehicles" refers to the first number mentioned above, "evacuee" refers to people who need to evacuate within the building, and "person evacuation vehicle" refers to the car 10 used for the evacuation of people.

[0048] First, in step S1 of the flow diagram in Fig. 3, the disaster information acquisition unit 111 of the control device 100 acquires information on the occurrence of a disaster in the building from the external server 300. In the following step S2, the control device 100 determines whether or not a disaster has occurred in the building or a disaster is expected to occur, based on the information on the occurrence of the disaster acquired in step S1. If a disaster has not occurred in the building or a disaster is not expected to occur, the control device 100 returns to step S1 to continue the process. On the other hand, if a disaster has occurred in the building or a disaster is expected to occur, the control device 100 next performs the process of step S3.

[0049] In step S3, the evacuation urgency determination unit 112 of the control device 100 determines the evacuation urgency of the disaster based on the information on the occurrence of the disaster acquired in step S1. If the evacuation urgency is high, i.e., if the evacuation urgency is "high," the elevator system starts emergency robot evacuation operation in step S4. On the other hand, if the evacuation urgency is not high, i.e., if the evacuation urgency is "low," the elevator system starts normal robot evacuation operation in step S5.

[0050] The flow diagram of Fig. 4 shows an example of the case where the above-mentioned first modified example is applied to the process of step S4 of Fig. 3, that is, the process related to the robot evacuation operation in an emergency. In this case, when the robot evacuation operation in an emergency is started, first, in step S101, the evacuation planner 113 of the control device 100 determines an evacuation floor based on the information on the occurrence of a disaster in the building acquired by the disaster information acquisition unit 111, particularly the type of disaster. In the following step S102, the evacuation planner 113 acquires information on the autonomous mobile body 20 that is to evacuate to the evacuation floor from the mobile body management server 200. After step S102, the control device 100 next performs the process of step S103.

[0051] In step S103, the evacuation plan unit 113 determines whether or not there are any autonomous moving bodies 20 remaining to evacuate, based on the information of the autonomous moving bodies 20 acquired in step S102. If there are no autonomous moving bodies 20 remaining to evacuate, the emergency robot evacuation operation ends. On the other hand, if there are any autonomous moving bodies 20 remaining to evacuate, the control device 100 next performs the process of step S104.

[0052] In step S104, the elevator utilization rate acquisition unit 114 of the control device 100 acquires the utilization rate of the elevator by people. In the following step S105, it is determined whether or not the utilization rate of the elevator by people acquired in step S104 is less than a certain value and the evacuation of people in the building can be considered to be completed, that is, whether or not the utilization rate is less than the above-mentioned standard utilization rate. If the utilization rate is not less than the standard utilization rate, the control device 100 next performs the process of step S106.

[0053] In step S106, the evacuation planning unit 113 determines the number of evacuation robots, i.e., the first number, to be 0. After step S106, the control device 100 returns to step S104 to continue the process. On the other hand, if the utilization rate is less than the reference utilization rate in step S105, the control device 100 next performs the process of step S107. In step S107, the evacuation planning unit 113 determines whether the number of evacuation robots, i.e., the first number, is an upper limit value. Here, the upper limit value of the number of evacuation robots (first number) is preset to a value equal to or less than the total number of elevator cars 10 in the building. If the number of evacuation robots (first number) is not the upper limit value, the control device 100 next performs the process of step S108.

[0054] In step S108, the evacuation planning unit 113 determines whether or not a certain time has passed since the previous increase in the number of evacuation robots (first number), that is, since the processing of step S109 described next was performed. If a certain time has passed since the previous increase in the number of evacuation robots (first number), the control device 100 then performs the processing of step S109.

[0055] In step S109, the evacuation planning unit 113 increases the number of evacuation robots (first number) by one. In this way, the evacuation planning unit 113 determines the number of evacuation robots (first number) and formulates an evacuation plan. After step S109, the control device 100 then performs processing of step S110. Also, if the number of evacuation robots is the upper limit value in step S107, or if a certain amount of time has not passed since the previous increase in the number of evacuation robots (first number) in step S108, the control device 100 performs processing of step S110 without performing processing of step S109.

[0056] In step S110, the elevator control unit 120 controls the cars 10 in accordance with the evacuation plan formulated by the evacuation plan unit 113. That is, the elevator control unit 120 dispatches the elevator cars 10 of the same number as the robot evacuation car number (first number) to the autonomous moving body 20. After step S110, the control device 100 then performs processing of step S111.

[0057] In step S111, the mobile object management server 200 controls the autonomous mobile object 20 according to the evacuation plan formulated by the evacuation plan unit 113. That is, the mobile object management server 200 transmits a command to the autonomous mobile object 20 that needs to be evacuated to the evacuation floor in the elevator car 10 dispatched in step S110. Then, the autonomous mobile object 20 that receives this command boards the car 10 dispatched in step S110. In the following step S112, when the car 10 on which the autonomous mobile object 20 boards arrives at the evacuation floor, the autonomous mobile object 20 disembarks from the car 10 at the evacuation floor. After step S112, the control device 100 returns to step S103 to continue the process, and repeats the processes from step S103 to step S112 until the evacuation of all the autonomous mobile objects 20 that need to be evacuated is completed.

[0058] According to such an operation example shown in the flow diagram of FIG. 4, when the elevator utilization rate is high, it is assumed that there are people remaining in the building who have not completed evacuation, and the first number is set to 0 and evacuation of the autonomous moving body 20 by the elevator is not performed. Then, after the elevator utilization rate has sufficiently decreased, the first number is increased and evacuation of the autonomous moving body 20 by the elevator is started. Even after evacuation of the autonomous moving body 20 by the elevator is started, if the elevator utilization rate becomes equal to or higher than the reference utilization rate, the first number is set to 0 again and evacuation of the autonomous moving body 20 by the elevator is temporarily stopped, and evacuation of people is prioritized. Therefore, when the urgency of evacuation of people in the disaster is high, evacuation by people using the elevator is prioritized, and evacuation and protection of people can be ensured. Then, after evacuation of the autonomous moving body 20 by the elevator is started, the first number is gradually increased as time passes, thereby enabling quick evacuation and protection of the autonomous moving body 20. In addition, by setting an upper limit on the first number, even if there are people who have not completed evacuation after evacuation of the autonomous moving body 20 by elevator has begun, an evacuation car 10 can be immediately dispatched to the people.

[0059] The flow diagram of Fig. 5 shows an example of the case where the above-mentioned second modified example is applied to the process of step S4 of Fig. 3, that is, the process related to the robot evacuation operation in an emergency. In this case, when the robot evacuation operation in an emergency is started, first, in step S201, the evacuation planner 113 of the control device 100 determines an evacuation floor based on the information on the occurrence of a disaster in the building acquired by the disaster information acquisition unit 111, particularly the type of disaster. In the following step S202, the evacuation planner 113 acquires information on the autonomous mobile body 20 that is to evacuate to the evacuation floor from the mobile body management server 200. After step S202, the control device 100 next performs the process of step S203.

[0060] In step S203, the evacuation plan unit 113 determines whether or not there are any autonomous moving bodies 20 remaining to evacuate, based on the information of the autonomous moving bodies 20 acquired in step S202. If there are no autonomous moving bodies 20 remaining to evacuate, the emergency robot evacuation operation ends. On the other hand, if there are any autonomous moving bodies 20 remaining to evacuate, the control device 100 next performs the process of step S204.

[0061] In step S204, the building inhabitant count acquisition unit 115 of the control device 100 acquires the number of remaining evacuees from the building system 400. In the following step S205, the evacuation planning unit 113 calculates the number of cars 10 that can be dispatched to the remaining evacuees without waiting time, i.e., the above-mentioned second number, based on the number of remaining evacuees acquired in step S204. Then, the calculated second number of cars 10 is set as evacuation cars. After step S205, the control device 100 next performs the process of step S206.

[0062] In step S206, the evacuation planning unit 113 determines whether the total number of human evacuation machines and robot evacuation machines, i.e., the sum of the first number and the second number, is equal to or greater than the total number of elevator cars 10 in the building. If the total number of human evacuation machines and robot evacuation machines (the sum of the first number and the second number) is equal to or greater than the total number of elevator cars 10 in the building, the control device 100 then performs the process of step S207.

[0063] In step S207, the evacuation planning unit 113 reduces the number of robot evacuation machines, i.e., the above-mentioned first number, by 1. After step S207, the control device 100 returns to step S206 to continue the process. On the other hand, if the total of the human evacuation machines and the robot evacuation machines (the total of the first number and the second number) is not equal to or greater than the total number of elevator cars 10 in the building in step S206, the control device 100 then performs the process of step S208.

[0064] In step S208, the evacuation planning unit 113 determines whether a certain time has passed since the previous increase in the number of evacuation robots (first number), that is, since the processing of step S209 described next was performed. If a certain time has passed since the previous increase in the number of evacuation robots (first number), the control device 100 then performs the processing of step S209.

[0065] In step S209, the evacuation planning unit 113 increases the number of evacuation robots (first number) by one. In this way, the evacuation planning unit 113 determines the number of evacuation robots (first number) and formulates an evacuation plan. After step S209, the control device 100 then performs the process of step S210. Also, if a certain amount of time has not passed since the previous increase in the number of evacuation robots (first number) in step S208, the control device 100 performs the process of step S210 without performing the process of step S209.

[0066] In step S210, the elevator control unit 120 controls the cars 10 in accordance with the evacuation plan formulated by the evacuation plan unit 113. That is, the elevator control unit 120 dispatches the elevator cars 10 of the same number as the robot evacuation car number (first number) to the autonomous moving body 20. After step S210, the control device 100 then performs processing of step S211.

[0067] In step S211, the mobile object management server 200 controls the autonomous mobile object 20 according to the evacuation plan formulated by the evacuation plan unit 113. That is, the mobile object management server 200 transmits a command to the autonomous mobile object 20 that needs to be evacuated to the evacuation floor in the elevator car 10 dispatched in step S210. Then, the autonomous mobile object 20 that receives this command boards the car 10 dispatched in step S210. In the following step S212, when the car 10 on which the autonomous mobile object 20 boards arrives at the evacuation floor, the autonomous mobile object 20 disembarks from the car 10 at the evacuation floor. After step S212, the control device 100 returns to step S203 to continue the process, and repeats the processes from step S203 to step S212 until the evacuation of all the autonomous mobile objects 20 that need to be evacuated is completed.

[0068] In the operation example shown in the flow diagram of FIG. 5, the evacuation plan unit 113 simulates evacuation by evacuees using an elevator, and calculates the waiting time until an elevator is dispatched to evacuees on each floor when the evacuees register an elevator call to evacuate using the elevator. Then, evacuation of the autonomous moving body 20 using the elevator is not performed until the waiting time on all floors becomes 0. Therefore, when the urgency of human evacuation in the disaster is high, evacuation by humans using the elevator is prioritized, and evacuation and protection of humans can be ensured. In addition, as many elevator cars 10 as possible can be used for evacuation of the autonomous moving body 20 within a range in which the elevator waiting time of the evacuees becomes 0, and after evacuation of the autonomous moving body 20 by the elevator is started, the first number can be increased stepwise over time, thereby enabling rapid evacuation and protection of the autonomous moving body 20. In addition, by setting an upper limit value for the first number, even if there are humans who have not completed evacuation after evacuation of the autonomous moving body 20 by the elevator is started, an evacuation elevator car 10 can be immediately dispatched to the humans.

[0069] The flow diagram of FIG. 6 shows an example of the process of step S5 of FIG. 3, that is, the process related to the normal robot evacuation operation. When the normal robot evacuation operation is started, first, in step S301, the evacuation planner 113 of the control device 100 determines an evacuation floor based on the information on the occurrence of a disaster in the building acquired by the disaster information acquisition unit 111, particularly the type of disaster. In the following step S302, the evacuation planner 113 acquires the predicted time of disaster occurrence in the information on the occurrence of a disaster in the building acquired by the disaster information acquisition unit 111. Then, in the further following step S303, the evacuation planner 113 acquires information on the autonomous mobile body 20 that is to evacuate to the evacuation floor from the mobile body management server 200. After step S303, the control device 100 next performs the process of step S304.

[0070] In step S304, the evacuation plan unit 113 determines whether or not there are any autonomous moving bodies 20 remaining to evacuate, based on the information of the autonomous moving bodies 20 acquired in step S303. If there are no autonomous moving bodies 20 remaining to evacuate, the normal robot evacuation operation ends. On the other hand, if there are any autonomous moving bodies 20 remaining to evacuate, the control device 100 next performs the process of step S305.

[0071] In step S305, the evacuation planning unit 113 determines whether the number of evacuating robots, i.e., the above-mentioned first number, is the upper limit. As described above, the upper limit of the number of evacuating robots (first number) is preset to a value equal to or less than the total number of elevator cars 10 in the building. If the number of evacuating robots (first number) has not reached the upper limit, the control device 100 next performs the process of step S306.

[0072] In step S306, the evacuation planning unit 113 increases the number of robot evacuation vehicles (first number) by one. In the following step S307, the evacuation planning unit 113 acquires information on the operation status of the elevator cars 10 in the building from the elevator control unit 120. Then, based on the operation status of the elevator cars 10, the evacuation planning unit 113 calculates the time until all of the autonomous moving bodies 20 that need to evacuate complete evacuation using all of the robot evacuation vehicles, i.e., the first number of cars 10. After step S307, the control device 100 next performs the process of step S308.

[0073] In step S308, the evacuation planning unit 113 compares the time required for the autonomous mobile body 20 to complete evacuation calculated in step S302 with the predicted disaster occurrence time acquired in step S302, and determines whether or not the evacuation of the autonomous mobile body 20 will be completed by the predicted disaster occurrence time. If the evacuation of the autonomous mobile body 20 is not completed by the predicted disaster occurrence time, the control device 100 returns to step S305 and continues the process. On the other hand, if the evacuation of the autonomous mobile body 20 is completed by the predicted disaster occurrence time, the evacuation planning unit 113 confirms the current number of evacuation robots (first number) and completes the formulation of the evacuation plan. Then, the control device 100 next performs the process of step S309.

[0074] Also, if the number of evacuation robots (first number) reaches the upper limit in step S305, the evacuation plan unit 113 sets the number of evacuation robots (first number) to the upper limit and completes the formulation of the evacuation plan. In this case, the control device 100 skips the processes from step S306 to step S308 and performs the process of step S309.

[0075] In step S309, the elevator control unit 120 controls the cars 10 in accordance with the evacuation plan formulated by the evacuation plan unit 113. That is, the elevator control unit 120 dispatches the elevator cars 10 of the same number as the robot evacuation car number (first number) to the autonomous moving body 20. After step S309, the control device 100 then performs processing of step S310.

[0076] In step S310, the mobile object management server 200 controls the autonomous mobile object 20 according to the evacuation plan formulated by the evacuation plan unit 113. That is, the mobile object management server 200 transmits a command to the autonomous mobile object 20 that needs to be evacuated to the evacuation floor in the elevator car 10 dispatched in step S309. Then, the autonomous mobile object 20 that receives this command boards the car 10 dispatched in step S309. In the following step S311, when the car 10 on which the autonomous mobile object 20 boards arrives at the evacuation floor, the autonomous mobile object 20 disembarks from the car 10 at the evacuation floor. After step S311, the control device 100 returns to step S304 to continue the process, and repeats the processes from step S304 to step S311 until the evacuation of all the autonomous mobile objects 20 that need to be evacuated is completed.

[0077] According to such an operation example shown in the flow diagram of Fig. 6, the minimum number of cars 10 that can complete the evacuation of the autonomous moving bodies 20 by the predicted time of disaster occurrence are used for the evacuation of the autonomous moving bodies 20, so people can also evacuate using the elevator while evacuating and protecting the autonomous moving bodies 20. Also, by setting an upper limit value for the first number, even if there are people who have not completed evacuation after the start of evacuation of the autonomous moving bodies 20 by the elevator, evacuation cars 10 can be immediately dispatched to the people.

[0078] In the elevator system according to this embodiment, if the transportation capacity of the elevator in the building is insufficient to evacuate the autonomous mobile body 20 in the building, the autonomous mobile body 20 may be notified to evacuate using an elevator in a building other than the building. Note that the other building referred to here is a building to which the autonomous mobile body 20 can travel via, for example, a lobby floor or a connecting passageway. In addition, if the disaster is a disaster such as flooding or tsunami that requires evacuation to a higher place as possible, a building to which the autonomous mobile body 20 can travel from the building to the ground via the other building may also be included in the other building.

[0079] In this case, the evacuation planning unit 113 estimates the grace period until the autonomous mobile body 20 in the building is damaged by the disaster. This grace period can be estimated as described above. The evacuation planning unit 113 determines whether or not the transportation capacity of the elevator in the building is insufficient to complete the evacuation of the autonomous mobile body 20 in the building before the estimated grace period has elapsed. If the transportation capacity of the elevator is insufficient, the evacuation planning unit 113 formulates an evacuation plan in which the autonomous mobile body 20 evacuates using an elevator in a building other than the building.

[0080] The mobile object management server 200 controls the operation of the autonomous mobile object 20 according to the evacuation plan formulated by the evacuation plan unit 113. That is, the mobile object management server 200 notifies the autonomous mobile object 20 to evacuate using an elevator in a building other than the building. Then, the autonomous mobile object 20 moves from the building to another building according to the notification from the mobile object management server 200, and evacuates using the elevator in the other building. In this case, the mobile object management server 200 functions as a notification unit that notifies the autonomous mobile object 20 to evacuate using an elevator in a building other than the building when the transportation capacity of the elevator in the building is insufficient to complete the evacuation of the autonomous mobile object 20 in the building before the above-mentioned grace period has elapsed. In this way, it is possible to reduce the possibility that the autonomous mobile object 20 will be damaged by a disaster when the autonomous mobile object 20 cannot evacuate in time by the occurrence of a disaster using only the elevator in the building.
