[0001] The present disclosure relates to an elevator system, a control method for an elevator system, and a program. [Background technology]

[0002] In the elevator system, the elevator control device includes a robot transport detection means for detecting whether the robot is being transported or not, a situation change detection means for detecting a change in the operating situation from normal operation to emergency operation, an emergency operation notification means for notifying the elevator-utilizing robot of the change in the operating situation from normal operation to emergency operation and information on the floors to stop at, a selection request receiving means for receiving a selection request from the elevator-utilizing robot for a ride continuation action or a dismounting action, a ride continuation ensuring means for invalidating the significance of detection by a safety device that monitors ride continuation when a ride continuation action is selected by the elevator-utilizing robot, and a dismounting action notification means for notifying the elevator-utilizing robot of the completion of preparations for dismounting when a dismounting action is selected by the elevator-utilizing robot.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-193863 Summary of the Invention [Problem to be solved by the invention]

[0004] In an elevator system such as that disclosed 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 chooses whether to continue riding or dismount. However, no consideration is given to human evacuation using the elevator in the event of a disaster, so if the autonomous mobile object chooses to continue riding during emergency operation following a disaster, this may affect human evacuation using the elevator. Conversely, if the autonomous mobile object chooses to dismount in a situation where there is relatively little need for humans to use the elevator to evacuate in the event of a disaster, the autonomous mobile object may be damaged by the disaster.

[0005] The present disclosure has been made to solve such problems, and its purpose is to provide an elevator system, an elevator system control method, and a program that, in the event of a disaster or in a situation where a disaster is expected, 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, and that can ensure the evacuation and protection of people while also enabling the evacuation and protection of the autonomous mobile objects.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Embodiments for implementing an elevator system, an elevator system control method, and a program according to the present disclosure will be described with reference to the accompanying drawings. In each drawing, identical or corresponding parts are designated by the same reference numerals, and redundant explanations are appropriately simplified or omitted. For convenience, the following description may express the positional relationship of each structure based on the illustrated state. Note that the present disclosure is not limited to the following embodiments, and any combination of the embodiments, any modification of any component of each embodiment, or any omission of any component of each embodiment are possible within the scope of the present disclosure.

[0012] Embodiment 1 A first embodiment of the present disclosure will be described with reference to Figs. 1 to 7. Fig. 1 is a block diagram showing the configuration of an elevator system. Fig. 2 is a diagram showing evacuation of an autonomous mobile 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 the configuration for realizing the functions of a control device and the like of the elevator system.

[0013] As shown in FIG. 1, the elevator system according to this embodiment includes a control device 100. 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 this disclosure is not limited to two. The number of cars 10 in the elevator system according to this disclosure may be three or more. Furthermore, the elevator system according to this disclosure is particularly suitable when the number of cars 10 is two or more, but the number of cars 10 may also be one.

[0014] An autonomous mobile body 20 is in operation in the building in which the elevator is installed. The autonomous mobile body 20 is, for example, a mobile robot, and is capable of moving autonomously. Each autonomous mobile body 20 is capable of communicating 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 status of each autonomous mobile body 20. The control device 100 and the mobile body management server 200 are connected to each other so that they can communicate bidirectionally. 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 regarding the occurrence of a disaster in a building in which the elevator is installed. The information regarding the occurrence of a disaster may be actual disaster information, predicted disaster information, or both. Actual disaster information is information regarding a disaster that has actually already occurred at the present time. Predicted disaster information is information regarding a disaster that may occur in the future. The information regarding the occurrence of a disaster includes the type and severity of the disaster. Furthermore, if the information regarding the occurrence of a disaster is actual disaster information, the information regarding the occurrence of a disaster further includes the time when the disaster occurred (disaster occurrence time), and if the information regarding the occurrence of a disaster is predicted disaster information, the information regarding the occurrence of a disaster further includes the time when the disaster is predicted to occur (predicted disaster occurrence time).

[0016] In the illustrated configuration example, the disaster information acquisition unit 111 acquires information about 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 about the occurrence of a disaster. The external server 300 provides, for example, any one or more of weather information, flood information, earthquake information, tsunami information, landslide information, and fire information as information about 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, emergency heavy rain warnings, information on record-breaking short-term heavy rain, and meteorological information related to significant heavy rain. 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 expressed, for example, by the amount of precipitation indicated in this information. The time of occurrence of the disaster (or the time it is expected to occur) is expressed, 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, current and predicted river water levels in the area where the building is located, flood forecasts (flood advisories, flood warnings, 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 these cases, the type of disaster in the information regarding the occurrence of a disaster is flood damage. The extent of the disaster is expressed, for example, by the amount of precipitation or river water level indicated in this information. The time of occurrence of the disaster (or the time it is expected to occur) is expressed, for example, by the time when the water level exceeding the flood danger level is actually observed, or the time when the water level is expected to exceed the flood danger level.

[0019] Examples of earthquake information that may be used as information regarding the occurrence of a disaster include earthquake detector readings in the area where the building is located, earthquake early warnings, seismic intensity reports, 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 earthquake occurrence, 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 alert, 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 indicated in this information. The time of occurrence of the disaster (or the time it is expected to occur) is indicated by the time of arrival or predicted time of arrival of the tsunami 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 a 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 severity 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 results of fire detectors installed in the building or in buildings nearby the building. In this case, the type of disaster in the information regarding the occurrence of a disaster is fire. The severity of the disaster is expressed, for example, by the number of detectors that detected the fire. The time when the disaster occurred is expressed, for example, by the time when a detector first detected 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 about the occurrence of a disaster acquired by the disaster information acquisition unit 111. As described above, the information about the occurrence of a disaster includes the type of disaster, the severity of the disaster, and the time of the disaster occurrence (or the predicted time of the 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. Alternatively, 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, if the disaster type is a fire, the evacuation urgency determination unit 112 determines the evacuation urgency to be "high." Furthermore, if the disaster type is a flood, and the disaster has already occurred, the evacuation urgency determination unit 112 determines the evacuation urgency to be "high." On the other hand, if the disaster type is a flood and the disaster has not yet occurred but is predicted 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 predicted occurrence time. That is, if the time from the current time to the predicted occurrence time is equal to or greater than a preset reference time, the evacuation urgency determination unit 112 determines the evacuation urgency to be "low." On the other hand, if the time from the current time to the predicted occurrence time is less than the reference time, the evacuation urgency determination unit 112 determines the evacuation urgency to be "high."

[0025] For other types of disasters, the evacuation urgency determination unit 112 also determines the evacuation urgency of the disaster based on the type of disaster, the severity of the disaster, whether the disaster has already occurred, and, if the disaster has not yet occurred, the time from the current time to the predicted time of occurrence, etc. In this case, generally, the greater the severity of the disaster, the higher the evacuation urgency of the disaster. Furthermore, if a disaster has already occurred, the higher the evacuation urgency of the disaster. Furthermore, if the disaster has not yet occurred, the shorter the time from the current time to the predicted time of occurrence, the higher the evacuation urgency of the disaster. Alternatively, for example, points may be preset for the type of disaster, the severity of the disaster, whether the disaster has already occurred, and, if the disaster has not yet occurred, the time from the current time to the predicted time of occurrence, and the evacuation urgency determination unit 112 may determine the evacuation urgency of the disaster based on the total value of these points.

[0026] The control device 100 further includes an evacuation planning unit 113. The evacuation planning 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 planning unit 113 includes at least a first number. The first number is the number of elevator cars 10 to be used for evacuation of the autonomous moving bodies 20 in the building in the event of the disaster. The evacuation planning 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 levels, "high" and "low." Therefore, the evacuation planning unit 113 determines the first number of vehicles to be a predetermined number when the evacuation urgency is "high," and when the evacuation urgency is "low," the evacuation planning unit 113 determines the first number of vehicles 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 cases 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 bodies 20 inside the building in the event of a disaster.

[0029] The evacuation plan formulated by the evacuation planning unit 113 includes the first number of vehicles as well as evacuation floors, etc. If the type of disaster is flooding, the evacuation planning unit 113 determines the evacuation floor to be an upper floor of the building. If the type of disaster is a fire or the like other than flooding, the evacuation planning unit 113 determines the evacuation floor to be a floor other than the floor where the disaster is occurring. 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 status of the autonomous moving bodies 20, i.e., the number of autonomous moving bodies 20 in the building, their current locations, whether the autonomous moving bodies 20 have elevator boarding capacity, etc., from the moving body management server 200. The evacuation planning unit 113 also acquires information on the operating status of the elevator cars 10 in the building from the elevator control unit 120. Then, the evacuation planning unit 113 formulates an evacuation plan for the people and autonomous moving bodies 20 in the building using the determined first number and evacuation floors, the status of the autonomous moving bodies 20, the operating status of the cars 10, etc.

[0031] The elevator control unit 120 controls the elevator cars 10 based on the evacuation plan formulated by the evacuation planning unit 113. Therefore, the elevator control unit 120 controls the cars 10 so that a first number of cars 10 determined by the evacuation planning unit 113 is used for the evacuation of the autonomous moving bodies 20 within the building in the event of the disaster. That is, the elevator control unit 120 dispatches the first number of cars 10 for the evacuation of the autonomous moving bodies 20. Furthermore, the mobile body management server 200 controls the operation of the autonomous moving bodies 20 so as to evacuate the autonomous moving bodies 20 based on the evacuation plan formulated by the evacuation planning unit 113. That is, the autonomous moving bodies 20 are caused to board the first number of cars 10 dispatched by the elevator control unit 120, and the autonomous moving bodies 20 are 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 evacuation and protection of the autonomous mobile bodies 20 can be achieved while ensuring the evacuation and protection of people.

[0033] Next, several modified examples of the method for determining the first number of elevators by the evacuation planning unit 113 will be described. First, in the first modified example, when the evacuation urgency level is "high," the first number of elevators is determined according to the utilization rate of the elevators 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 utilization rate of the elevators by people in the building. The utilization rate of the elevators by people is, for example, the proportion of time during a certain period that the elevator cars 10 are in operation for people to use the elevators (board the cars 10).

[0034] The elevator utilization rate acquisition unit 114 obtains the operating time of each car 10 due to human use, and calculates the utilization rate of each car 10 by humans, i.e., the utilization rate of the elevator by humans, using, for example, the running state of each car 10, the call registration status for each car 10, the load on each car 10, etc. 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 in accordance with 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 increases, and increases the first number as the elevator utilization rate by people decreases. In this way, evacuation by people using the elevator is prioritized, while the autonomous moving bodies 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, for example, to a utilization rate value at which the evacuation of people in the building can be considered complete. That is, in this case, the evacuation planning unit 113 determines whether 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 has more than two levels, "high" and "low," then the evacuation planning unit 113 determines the first number of elevators in accordance with the elevator utilization rate by people acquired by the elevator utilization rate acquisition unit 114 when the urgency of evacuation of people in the building is equal to or greater than a predetermined reference urgency level. Furthermore, when the urgency of evacuation of people in the building is equal to or greater than the aforementioned reference urgency level, the evacuation planning unit 113 may gradually increase the first number of elevators after the elevator utilization rate falls below the aforementioned reference urgency. Note that when the evacuation urgency level has two levels, "high" and "low," the reference urgency level is set to "high." Therefore, when the evacuation urgency level is "high," the evacuation urgency level is equal to or greater than the reference urgency level, and when the evacuation urgency level is "low," the evacuation urgency level is less than the reference urgency level.

[0038] Next, a second modified example of the method for determining the first number of units by the evacuation planning unit 113 will be described. In this second modified example, when the evacuation urgency level is "high," the first number of units 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 is equipped with, for example, an access control system, a surveillance camera system, etc., and through these systems, the number of people staying in the building, i.e., the building. The building number 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 in accordance with 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 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] Furthermore, for 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 occupancy 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. 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 with the first modified example described above, if this second modified example is generalized to a case where the evacuation urgency level is more than two levels, "high" and "low," then when the urgency level of evacuation of people in the building is equal to or higher than a preset reference urgency level, the evacuation planning unit 113 determines the first number of elevators in accordance with the number of people remaining in the building acquired by the building population acquisition unit 115. Furthermore, when the urgency level of evacuation of people in the building is equal to or higher than the reference urgency level described above, the evacuation planning unit 113 may calculate a second number of elevator cars 10, which is the number of elevator cars 10 required to evacuate the people remaining in the building 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 for determining the first number by the evacuation planning unit 113 will be described. In this third modified example, when the evacuation urgency level is "low," the first number is determined according to the grace period until the autonomous mobile bodies 20 in the building are damaged by a disaster. As described above, the mobile body management server 200 manages the status of the autonomous mobile bodies 20. In this third modified example, when the evacuation urgency level is "low," the evacuation planning unit 113 acquires information on the status of the autonomous mobile bodies 20, i.e., the number of autonomous mobile bodies 20 in the building and their respective current locations, from the mobile body management server 200. In addition, the evacuation planning unit 113 acquires information on the operating status of the elevator cars 10 in the building from the elevator control unit 120.

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

[0045] Here, if this third variant is generalized to cases where the evacuation urgency level is more than two levels, "high" and "low," then when the urgency level of evacuation for people in the building is less than a predetermined standard urgency level, 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 the first number to be 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 first or second modified example with this third modified example. In this case, the standard urgency level in the first or second modified example is a standard for determining whether the evacuation urgency level is high, while the standard urgency level in the third modified example is a standard for determining whether the evacuation urgency level is low. Therefore, particularly when the evacuation urgency level has three or more levels, the standard urgency level in the first or second modified example may be different from the standard urgency level 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 charts in Figures 3 to 6. In these flow charts, "robot" refers to the autonomous mobile body 20, "robot evacuation unit" refers to the car 10 used for the evacuation of the autonomous mobile body 20, "number of robot evacuation units" refers to the first number mentioned above, "evacuee" refers to people who need to evacuate within the building, and "person evacuation unit" 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 about the occurrence of a disaster in the building from the external server 300. In the following step S2, the control device 100 determines whether a disaster has occurred in the building or whether a disaster is predicted to occur, based on the information about the disaster acquired in step S1. If a disaster has not occurred in the building or a disaster is not predicted to occur, the control device 100 returns to step S1 and continues processing. On the other hand, if a disaster has occurred in the building or a disaster is predicted to occur, the control device 100 next performs processing in 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 about 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 in which the first modified example described above is applied to the process of step S4 of Fig. 3, i.e., 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 planning unit 113 of the control device 100 determines an evacuation floor based on information regarding 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 planning unit 113 acquires information about the autonomous mobile body 20 that will evacuate to the evacuation floor from the mobile body management server 200. After step S102, the control device 100 then performs the process of step S103.

[0051] In step S103, the evacuation planning unit 113 determines whether or not any autonomous mobile bodies 20 remain to evacuate, based on the information about the autonomous mobile bodies 20 acquired in step S102. If no autonomous mobile bodies 20 remain to evacuate, the emergency robot evacuation operation ends. On the other hand, if any autonomous mobile bodies 20 remain to evacuate, the control device 100 then 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 the utilization rate of the elevator by people acquired in step S104 is below a certain value and the evacuation of people in the building can be considered complete, that is, whether the utilization rate is below the aforementioned standard utilization rate. If the utilization rate is not below the standard utilization rate, the control device 100 then performs the process of step S106.

[0053] In step S106, the evacuation planning unit 113 determines the number of evacuation robots, i.e., the aforementioned first number, to be 0. After step S106, the control device 100 returns to step S104 to continue processing. On the other hand, if the utilization rate is less than the reference utilization rate in step S105, the control device 100 then performs processing in step S107. In step S107, the evacuation planning unit 113 determines whether the number of evacuation robots, i.e., the aforementioned first number, is equal to or greater than the upper limit. Here, the upper limit 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 equal to the upper limit, the control device 100 then performs processing in step S108.

[0054] In step S108, 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 S109, which will be described next, was performed. If the 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 the 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 number of evacuation robots (first number) was previously increased in step S108, the control device 100 performs the processing of step S110 without performing the 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 number of elevator cars 10 equal to the number of robot evacuation cars (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 in accordance with 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 an evacuation floor in the elevator car 10 that was dispatched in step S110. Then, the autonomous mobile object 20 that received this command boards the car 10 that was dispatched in step S110. In the following step S112, when the car 10 carrying the autonomous mobile object 20 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 processing, and repeats the processing from step S103 to step S112 until the evacuation of all autonomous mobile objects 20 that need to be evacuated is completed.

[0058] According to the operation example shown in the flow chart of FIG. 4 , when the elevator utilization rate is high, it is determined that there are people remaining in the building who have not yet evacuated, and the first number of elevators is set to 0, and evacuation of the autonomous moving bodies 20 by elevators is not performed. Then, after the elevator utilization rate has sufficiently decreased, the first number of elevators is increased, and evacuation of the autonomous moving bodies 20 by elevators is started. Furthermore, even after evacuation of the autonomous moving bodies 20 by elevators has started, if the elevator utilization rate becomes equal to or greater than the reference utilization rate, the first number of elevators is again set to 0, and evacuation of the autonomous moving bodies 20 by elevators 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 elevators is prioritized, and evacuation and protection of people can be ensured. Then, after evacuation of the autonomous moving bodies 20 by elevators has started, the first number of elevators is gradually increased over time, thereby enabling rapid evacuation and protection of the autonomous moving bodies 20. Furthermore, by setting an upper limit on the first number, even if there are people who have not yet completed their evacuation after the autonomous moving body 20 has started evacuation by elevator, an evacuation car 10 can be immediately dispatched to the people.

[0059] The flow diagram of Fig. 5 shows an example in which the second modified example described above is applied to the process of step S4 of Fig. 3, i.e., 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 planning unit 113 of the control device 100 determines an evacuation floor based on information regarding 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 planning unit 113 acquires information about the autonomous mobile body 20 that will evacuate to the evacuation floor from the mobile body management server 200. After step S202, the control device 100 then performs the process of step S203.

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

[0061] In step S204, the building occupancy 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, i.e., the second number mentioned above, based on the number of remaining evacuees acquired in step S204. Then, the calculated second number of cars 10 is designated as evacuation cars. After step S205, the control device 100 next performs the processing 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 and continues processing. On the other hand, if in step S206 the total number of human evacuation machines and robot evacuation machines (the total of the first number and the second number) is not greater than or equal to the total number of elevator cars 10 in the building, the control device 100 then performs processing in 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, which will be described next, was performed. If the 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 processing of step S210. Furthermore, if a certain amount of time has not elapsed since the previous increase in the number of evacuation robots (first number) in step S208, the control device 100 performs the processing of step S210 without performing the processing 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 number of elevator cars 10 equal to the number of robot evacuation cars (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 in accordance with 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 that was dispatched in step S210. Then, the autonomous mobile object 20 that received this command boards the car 10 that was dispatched in step S210. In the following step S212, when the car 10 that the autonomous mobile object 20 is in 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 processing, and repeats the processing from step S203 to step S212 until the evacuation of all autonomous mobile objects 20 that need to be evacuated is completed.

[0068] In the operation example shown in the flow chart of FIG. 5 , the evacuation planning unit 113 simulates evacuation by evacuees using elevators, and when an evacuee registers an elevator call to evacuate using an elevator, calculates the waiting time until an elevator is dispatched to the evacuee at each floor. Then, evacuation of the autonomous moving body 20 using an elevator is not performed until the waiting times at all floors become zero. Therefore, when the urgency of human evacuation in the disaster is high, evacuation by humans using elevators is prioritized, ensuring the evacuation and protection of humans. Furthermore, as many cars 10 as possible can be used for the evacuation of the autonomous moving body 20 as possible within a range in which the evacuee's elevator waiting time becomes zero. Furthermore, after evacuation of the autonomous moving body 20 by elevator begins, the first number can be gradually increased over time, thereby enabling the autonomous moving body 20 to be quickly evacuated and protected. Furthermore, by setting an upper limit on the first number, evacuation cars 10 can be immediately dispatched to humans even if there are humans who have not yet completed evacuation after evacuation of the autonomous moving body 20 by elevator begins.

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

[0070] In step S304, the evacuation planning unit 113 determines whether or not any autonomous mobile bodies 20 remain to evacuate, based on the information about the autonomous mobile bodies 20 acquired in step S303. If no autonomous mobile bodies 20 remain to evacuate, the normal robot evacuation operation ends. On the other hand, if any autonomous mobile bodies 20 remain to evacuate, the control device 100 then 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 then 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 have completed evacuation using all of the robot evacuation vehicles, i.e., all of the first number of cars 10. After step S307, the control device 100 then performs the processing 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 time of disaster occurrence acquired in step S302, and determines whether or not the evacuation of the autonomous mobile body 20 will be completed by the predicted time of disaster occurrence. If the evacuation of the autonomous mobile body 20 is not completed by the predicted time of disaster occurrence, the control device 100 returns to step S305 and continues processing. On the other hand, if the evacuation of the autonomous mobile body 20 will be completed by the predicted time of disaster occurrence, the evacuation planning unit 113 finalizes the current number of evacuation robots (first number) and completes the formulation of the evacuation plan. Then, the control device 100 next performs processing in step S309.

[0074] Furthermore, if the number of evacuation robots (first number) reaches the upper limit in step S305, the evacuation planning 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 of steps S306 to S308 and proceeds to 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 number of elevator cars 10 equal to the number of robot evacuation cars (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 in accordance with 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 that was dispatched in step S309. Then, the autonomous mobile object 20 that received this command boards the car 10 that was dispatched in step S309. In the following step S311, when the car 10 carrying the autonomous mobile object 20 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 processing, and repeats the processing from step S304 to step S311 until the evacuation of all autonomous mobile objects 20 that need to be evacuated is completed.

[0077] According to the operation example shown in the flow chart 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. Furthermore, 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 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 a 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 in question. Note that the other building referred to here is one to which the autonomous mobile body 20 can travel between the building in question and the elevator via, for example, a lobby floor or a connecting passageway. Furthermore, if the disaster in question is a flood, tsunami, or other disaster that requires evacuation to as high a place as possible, a building to which the autonomous mobile body 20 can travel from the building in question via the ground may also be included as 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 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 in question.

[0080] The mobile object management server 200 controls the operation of the autonomous mobile object 20 in accordance with the evacuation plan formulated by the evacuation planning 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 current building. Then, in accordance with the notification from the mobile object management server 200, the autonomous mobile object 20 moves from the current building to another building and evacuates using the elevator in that 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 current building when the transportation capacity of the elevator in the current building is insufficient to complete the evacuation of the autonomous mobile object 20 from the current building before the aforementioned 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 if the elevator in the current building alone is not enough to allow the autonomous mobile object 20 to evacuate in time before a disaster occurs.
