Description

[Technical Field]

[0001] The present disclosure relates to an elevator management device, a management method, and a management program. [Background technology]

[0002] Patent Document 1 discloses an example of an elevator system, in which, when an emergency earthquake alert is received in a building where the elevator is installed, a controlled operation is performed in response to long-period vibrations, such as stopping the car at the nearest floor and allowing passengers to exit the elevator. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-153520 Summary of the Invention [Problem to be solved by the invention]

[0004] In elevator systems such as those described in Patent Document 1, controlled operation is performed upon receiving an Earthquake Early Warning. Because the Earthquake Early Warning is information about the earthquake that has occurred, it does not take into account information about each building. Meanwhile, the response of a building to long-period vibrations may differ depending on the structure of the building, such as its height and strength. For this reason, when an Earthquake Early Warning is issued following an earthquake, controlled operation is performed uniformly in both buildings that require a response to the earthquake and buildings that do not require a response. At this time, unnecessary controlled operation can reduce operational efficiency in buildings that do not require a response.

[0005] The present disclosure relates to solving such problems, and provides an elevator management device, management method, and management program that can deal with long-period vibrations without unnecessarily reducing operation efficiency. [Means for solving the problem]

[0006] The elevator management device according to the present disclosure includes a receiving unit that receives long-period seismic motion data included in earthquake early warnings distributed by an external distribution agency; an estimation unit that estimates the class of long-period seismic motion for each of a plurality of buildings based on building information stored in advance for each of the plurality of buildings and the long-period seismic motion data received by the receiving unit; a target management unit that narrows down elevators installed in each of the plurality of buildings to which a command to perform controlled operation during long-period vibration is to be output based on the class estimated by the estimation unit; and a command unit that outputs the command to perform controlled operation to the elevators installed in each of the plurality of buildings narrowed down as the command targets by the target management unit.

[0007] The elevator management method according to the present disclosure is a method in which a computer receives long-period ground motion data included in earthquake early warnings distributed from an external distribution agency, estimates the class of long-period ground motion for each of a plurality of buildings based on building information stored in advance for each of the plurality of buildings and the received long-period ground motion data, narrows down elevators installed in each of the plurality of buildings to which a command to perform controlled operation during long-period vibration is to be output based on the estimated long-period ground motion class, and outputs the command to perform controlled operation to the elevators installed in each of the plurality of buildings narrowed down as the command targets.

[0008] The elevator management program according to the present disclosure causes a computer to receive long-period seismic motion data included in earthquake early warnings distributed from an external distribution agency, estimate the class of long-period seismic motion for each of a plurality of buildings based on pre-stored building information for each of the plurality of buildings and the received long-period seismic motion data, narrow down elevators installed in each of the plurality of buildings to which a command to perform controlled operation during long-period vibrations is to be output based on the estimated long-period seismic motion class, and output the command to perform controlled operation to the elevators installed in each of the plurality of buildings narrowed down as the command targets. [Effects of the Invention]

[0009] According to the management device, management method, or management program disclosed herein, it becomes possible to deal with long-period vibrations without reducing the elevator's operating efficiency more than necessary. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a configuration diagram of a management system according to a first embodiment. [Figure 2] 4 is a flowchart showing an example of the operation of the management system according to the first embodiment. [Figure 3] 1 is a hardware configuration diagram of a main part of a management system according to a first embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0011] The embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals, and redundant explanations are appropriately simplified or omitted. Note that the subject matter of the present disclosure is not limited to the following embodiments, and any component of the embodiments may be modified or omitted within the scope of the gist of the present disclosure.

[0012] Embodiment 1 FIG. 1 is a configuration diagram of a management system 1 according to the first embodiment.

[0013] The management system 1 is applied to a plurality of elevators 2. The management system 1 is a system that manages the plurality of elevators 2. The management system 1 may include some or all of the plurality of elevators 2 as devices within the system, or may manage some or all of the plurality of elevators 2 as devices outside the system.

[0014] Each elevator 2 is installed in a building 3 having multiple floors. In this example, the management system 1 manages multiple elevators 2 installed in multiple buildings 3. A single building 3 may be installed with a single elevator 2 or multiple elevators 2. In the building 3 to which the elevator 2 is applied, a hoistway, which is a space spanning multiple floors, is installed. In this example, each elevator 2 includes a hoisting machine 4, a main rope 5, a car 6, a counterweight 7, and a control panel 8.

[0015] The hoisting machine 4 includes a motor that generates driving force and a sheave that rotates by the driving force generated by the motor. The hoisting machine 4 is disposed, for example, at the upper or lower part of the hoistway. Alternatively, if a machine room is provided, for example, above the hoistway, the hoisting machine 4 may be disposed in the machine room.

[0016] The main ropes 5 are ropes that support the loads of the car 6 and counterweight 7 in the hoistway. The main ropes 5 are wound around the sheaves of the hoisting machine 4. The main ropes 5 support the load of the car 6 on one side of the sheaves of the hoisting machine 4. The main ropes 5 support the load of the counterweight 7 on the other side of the sheaves of the hoisting machine 4.

[0017] The car 6 is a device that travels up and down the hoistway to transport passengers between multiple floors. The counterweight 7 is a device that balances the loads acting on both sides of the sheave of the hoisting machine 4 between the car 6 and the counterweight 7. The car 6 and counterweight 7 travel in opposite directions in the hoistway by the driving force generated by the motor of the hoisting machine 4.

[0018] The control panel 8 is a device that controls the operation of the elevator 2. The operation of the elevator 2 includes, for example, the running of the car 6 in the elevator shaft. The control panel 8 is disposed, for example, at the top or bottom of the elevator shaft. Alternatively, if a machine room is provided above the elevator shaft, the control panel 8 may be disposed in the machine room. In this example, the control panel 8 is equipped with a function that operates in response to external commands. For example, when the control panel 8 receives an external command to perform controlled operation during long-period vibration, it executes the controlled operation.

[0019] The control panel 8 executes controlled operation during long-period vibration, for example, as follows: For example, when a passenger is in the car 6, the control panel 8 stops the car 6 at the nearest floor and allows the passenger to exit. After the passenger exits, the control panel 8 runs the car 6 and stops it at a non-resonance floor. A non-resonance floor is, for example, a floor where resonance of the main rope 5 and other equipment of the elevator 2 is unlikely to occur in the natural period of the building 3. A non-resonance floor is, for example, set in advance in the control panel 8.

[0020] The management system 1 includes multiple remote monitoring devices 9. Each remote monitoring device 9 corresponds to one of the elevators 2. The remote monitoring device 9 is a device that remotely monitors the status of the corresponding elevator 2. The remote monitoring device 9 is, for example, located in the building 3 in which the corresponding elevator 2 is installed. The remote monitoring device 9 may be part of the corresponding elevator 2. The remote monitoring device 9 is connected to the elevator 2's equipment, such as a control panel 8, so as to acquire status information of the corresponding elevator 2. The remote monitoring device 9 is connected to a communication network 10 so as to communicate information collected from the elevator 2. The communication network 10 may include, for example, a wide-area network such as the Internet or a telephone network, or a local network such as a LAN (Local Area Network). The remote monitoring device 9 has a function of issuing an alert to the outside via the communication network 10 when an abnormality, such as a failure, occurs in the elevator 2. The remote monitoring device 9 also has a function of outputting commands input from the outside via the communication network 10 to the control panel 8. It should be noted that a single remote monitoring device 9 may correspond to, for example, a plurality of elevators 2 installed in the same building 3.

[0021] The management system 1 includes a management device 11. The management device 11 is a device that performs information processing for managing multiple elevators 2. The management device 11 is connected to a communication network 10 so that it can communicate with external devices. The management device 11 is, for example, a computer system including one or more server devices. Here, a computer system including one or more devices may be simply referred to as a computer. The multiple server devices that make up the management device 11 may be located in different locations. In this case, the multiple server devices communicate information with each other, for example, via the communication network 10. Some or all of the functions of the management device 11 may be implemented, for example, by processing or storage resources on a cloud service. The management device 11 includes a memory unit 12, a receiving unit 13, an estimation unit 14, a target management unit 15, and a command unit 16.

[0022] The memory unit 12 is a part that has a function of storing information. The memory unit 12 stores building information about each building 3 in which an elevator 2 is installed in advance. The building information includes, for example, structural information such as the location of the building 3, the height and strength of the building 3, the natural period of the building 3, the response spectrum of the building 3, and the identifiers of the elevators 2 installed in the building 3. The memory unit 12 may store information about each elevator 2 in advance. The information about the elevator 2 includes, for example, the identifier of the elevator 2, the range of floors on which the elevator 2 runs, or other information.

[0023] The receiving unit 13 is a component equipped with a function for receiving long-period seismic motion data distributed from an external distribution agency 17. The receiving unit 13 receives, for example, long-period seismic motion data included in earthquake alerts distributed from the distribution agency 17 via the communication network 10. The distribution agency 17 includes, for example, public institutions such as the Japan Meteorological Agency, or other organizations such as businesses. The earthquake alert is, for example, an alert that distributes information about an earthquake when it occurs. The earthquake alert is, for example, an emergency earthquake alert distributed by the Japan Meteorological Agency. The earthquake alert includes, for example, information such as the location of the epicenter and the intensity of the earthquake. The earthquake alert includes long-period seismic motion data. The long-period seismic motion includes, for example, seismic motion with a period of approximately 1 second to 8 seconds. The long-period seismic motion data includes, for example, information on a scale representing the magnitude of shaking for long-period seismic motion. Here, the higher the scale, the greater the shaking. In this example, four scales, from scale 1 to scale 4, are provided. Note that the scale may be three or fewer or five or more. In this example, the long-period ground motion data includes information on the class of each period.

[0024] The estimation unit 14 is a part equipped with a function to estimate the class of long-period ground motion for each building 3 in which an elevator 2 is installed. When the receiving unit 13 receives long-period ground motion data, the estimation unit 14 estimates the class for each building 3. The estimation unit 14 estimates the class of long-period ground motion, for example, based on building information stored in the memory unit 12 or the like and the long-period ground motion data received by the receiving unit 13. For example, the estimation unit 14 refers to the class of the natural period of each building 3 from the classes by period in the long-period ground motion data, and uses the referred class as the class estimation result for each building 3. The estimation unit 14 may also estimate the class for each building 3 using other methods.

[0025] The estimation unit 14 may also estimate other information about the class. The estimation unit 14 estimates the predicted arrival time of long-period ground motion for each building 3 that has an elevator 2. The estimation unit 14 estimates the predicted arrival time of long-period ground motion based on, for example, the time of occurrence of the earthquake, the position of the epicenter, and the position of the building 3.

[0026] The target management unit 15 is a part that has a function of managing command targets to which a command to perform controlled operation during long-period vibration is output. The target management unit 15 narrows down the elevators 2 installed in each building 3 to which a command to perform controlled operation during long-period vibration is output, for example, based on the class estimated by the estimation unit 14. The target management unit 15 narrows down the command targets to, for example, elevators 2 installed in buildings 3 whose class estimated by the estimation unit 14 is higher than a preset standard. In this example, the target management unit 15 narrows down the command targets to elevators 2 installed in buildings 3 whose class estimates by the estimation unit 14 are class 4 and class 3.

[0027] The target management unit 15 may set priorities for elevators 2 narrowed down as command targets. The priorities are set based on, for example, information estimated by the estimation unit 14. The target management unit 15 sets the priorities based on, for example, the estimated class. The target management unit 15 may set the estimated class itself as the priority. For example, the target management unit 15 sets the priority of an elevator 2 installed in a building 3 estimated by the estimation unit 14 to be higher than the priority of an elevator 2 installed in a building 3 estimated by the estimation unit 14 to be 3. The target management unit 15 may set priorities based on, for example, the estimated class, and then set priorities within the class based on the predicted arrival time. For example, the target management unit 15 may set a higher priority to an elevator 2 installed in a building 3 with a faster predicted arrival time among elevators 2 installed in buildings 3 in class 4. The target management unit 15 may set priorities using other methods. For example, the target management unit 15 may set the priority to a value obtained by multiplying each of the quantified class and predicted arrival time by a weight and adding the weights together. In this case, the target management unit 15 calculates the priority by, for example, setting the weight of the class to a value greater than the weight of the predicted arrival time. The target management unit 15 may set the priority based on building information or information about the elevators 2. For example, for elevators 2 installed in buildings 3 with the same class and similar predicted arrival times, the target management unit 15 may set the priority of the elevators 2 operating on higher floors higher than the priority of the elevators 2 operating on lower floors. For example, when an elevator 2 for higher floors and an elevator 2 for lower floors are installed in the same building 3, the target management unit 15 may set the priority of the elevator 2 for higher floors higher than the priority of the elevator 2 for lower floors.

[0028] The command unit 16 is a part equipped with a function for outputting commands to each elevator 2 to perform controlled operation. The command unit 16 outputs commands to the elevators 2, for example, via the communication network 10 and the remote monitoring device 9. The command unit 16 sequentially outputs commands to each of the elevators 2 narrowed down as command targets by the target management unit 15. When priorities are set by the target management unit 15, the command unit 16 outputs commands according to the set priorities. For example, the command unit 16 outputs commands to elevators 2 in descending order of priority so that commands can be output earlier to elevators 2 with higher priorities. For example, the command unit 16 outputs a command to an elevator 2 installed in a building 3 of level 4, and then outputs a command to an elevator 2 installed in a building 3 of level 3. For example, the command unit 16 may output commands to elevators 2 installed in buildings 3 of level 4 in descending order of predicted arrival times.

[0029] Here, each of the multiple elevators 2 installed in a single building 3 may be narrowed down as a command target by the target management unit 15. In this case, the command unit 16 may designate one of the multiple elevators 2 installed in the building 3 as a representative elevator and output a command to the representative elevator. The building 3 is an example of a first building. The command unit 16 selects one of the multiple elevators 2 installed in the building 3 as the representative elevator. For example, if one of the elevators 2 is pre-set as a representative elevator in the building information, the command unit 16 selects the representative elevator in accordance with the building information. The command unit 16 may select the elevator 2 with the highest priority as the representative elevator, for example, based on the priority set by the target management unit 15. The command unit 16 outputs a command to perform controlled operation to the representative elevator, but does not output the command to other elevators 2 installed in the same building 3. In this case, the command unit 16 outputs, to the representative elevator, a command to perform controlled operation as well as a command to cause the other elevators 2 to perform controlled operation.

[0030] For example, consider a case where three elevators 2, A, B, and C, are installed in a single building 3. The control unit 16 selects elevator A as the representative elevator based on building information, etc. At this time, the control unit 16 outputs a command to perform controlled operation to the elevator 2 of elevator A, but does not output the same command to the elevators 2 of elevators B and C. Along with the command, the control unit 16 outputs a command to the elevator 2 of elevator A to cause the elevators 2 of elevators B and C to perform controlled operation. Based on the command from the control unit 16, the control panel 8 of the elevator 2 of elevator A performs controlled operation of elevator A and outputs a command to perform controlled operation to the control panels 8 of the elevators 2 of elevators B and C. The elevators 2 of elevators B and C perform controlled operation based on the command from the elevator 2 of elevator A.

[0031] The command unit 16 may output a command to perform controlled operation to each of a plurality of elevators 2 installed in a single building 3. The command unit 16 may select whether to output a command to a representative elevator or to each elevator 2, depending on, for example, the total number of elevators 2 narrowed down as targets for the command.

[0032] The command unit 16 may re-output a command when it fails to output a command to the elevator 2. The command unit 16 determines that the output of the command has failed, for example, when a preset time has elapsed since the command was output to the elevator 2 and the elevator 2 is not performing controlled operation. The command unit 16 acquires information on whether controlled operation is being performed, for example, via the remote monitoring device 9. The command unit 16 may determine that the output of the command has failed, for example, based on an error message transmitted from any device on the communication path of the output command. The command unit 16 may prioritize the re-output of a command to the elevator 2 installed in a building 3 with a relatively high rank over the initial output of a command to the elevator 2 installed in a building 3 with a relatively low rank. In this case, the building 3 with a relatively high rank is an example of a second building, and the building 3 with a relatively low rank is an example of a third building. The rank of the second building is higher than that of the third building.

[0033] For example, consider a case where class 4 is estimated for facility P, which is a building 3, and class 3 is estimated for facility Q, which is another building 3. In this case, command unit 16 outputs a command to elevator 2 installed in facility P before outputting a command to elevator 2 installed in facility Q. Thereafter, command unit 16 determines that the output of the command to elevator 2 installed in facility P has failed. In this case, command unit 16 re-outputs a command to elevator 2 installed in facility P before outputting a command to elevator 2 installed in facility Q.

[0034] When the command unit 16 fails to output a command to the representative elevator, it may output a command to another elevator 2 installed in the same building 3. The command unit 16, for example, selects one of the elevators 2 installed in the building 3 that is not the representative elevator from among the multiple elevators 2 installed in the building 3. The command unit 16 outputs a command to perform controlled operation to the selected elevator 2, but does not output the command to other elevators 2 installed in the same building 3, including the representative elevator. In this case, the command unit 16 outputs, to the selected elevator 2, a command to perform controlled operation, as well as a command to have the other elevators 2 perform controlled operation.

[0035] For example, consider a case where three elevators 2, A, B, and C, are installed in a single building 3. The command unit 16 selects elevator A as the representative elevator based on building information, etc. At this time, the command unit 16 outputs a command to perform controlled operation to the elevator 2 of elevator A, but does not output the command to the elevators 2 of elevators B and C. After that, the command unit 16 determines that the output of the command to the elevator 2 of elevator A has failed. At this time, the command unit 16 selects another elevator 2 of elevator A as the output destination of the command. The command unit 16 selects elevator B as the output destination of the command based on criteria such as the order of identifier numbers. Note that the command unit 16 may select the output destination of the command based on other criteria such as the priority set by the target management unit 15 or the number of past command output failures. The command unit 16 outputs a command to perform controlled operation to the selected elevator 2 of elevator B, but does not output the command to the elevators 2 of elevators A and C. Along with this command, the command unit 16 outputs a command to the elevator 2 of Unit B to cause the elevators 2 of Units A and C to perform controlled operation. The control panel 8 of the elevator 2 of Unit B performs controlled operation of Unit B based on the command from the command unit 16, and outputs a command to perform controlled operation to the control panels 8 of the elevators 2 of Units A and C. The elevators 2 of Units A and C perform controlled operation based on the command from the elevator 2 of Unit B.

[0036] Next, an example of the operation of the management system 1 will be described with reference to FIG. FIG. 2 is a flowchart showing an example of the operation of the management system 1 according to the first embodiment. FIG. 2 shows an example of processing in the management device 11.

[0037] In step S01, the receiving unit 13 receives an earthquake early warning distributed by the distribution organization 17. The receiving unit 13 reads the long-period seismic motion data included in the earthquake early warning. Thereafter, the processing of the management device 11 proceeds to step S02.

[0038] In step S02, the estimation unit 14 estimates the class of long-period ground motion for each building 3 in which an elevator 2 is installed, based on the building 3 information and the long-period ground motion data. The estimation unit 14 may also estimate the predicted arrival time of the long-period ground motion. Thereafter, the processing of the management device 11 proceeds to step S03.

[0039] In step S03, the target management unit 15 narrows down the elevators 2 to be command targets based on the estimation result of the estimation unit 14. The target management unit 15 may set priorities along with the narrowing down. Thereafter, the processing of the management device 11 proceeds to step S04.

[0040] In step S04, the command unit 16 compares the total number of elevators 2 narrowed down as command targets with a preset threshold. If the total number of elevators 2 to be command targets is greater than the threshold, the processing of the management device 11 proceeds to step S05. On the other hand, if the total number of elevators 2 to be command targets is not greater than the threshold, the processing of the management device 11 proceeds to step S06.

[0041] In step S05, the command unit 16 selects a representative elevator. For example, the command unit 16 determines whether other elevators 2 installed in the same building 3 have been narrowed down as command targets for the elevator 2 that has been narrowed down as a command target. When multiple elevators 2 installed in the same building 3 have been narrowed down as command targets, the command unit 16 selects a representative elevator from the multiple elevators 2 based on, for example, building information about the building 3. The command unit 16 performs a process of selecting a representative elevator for each of the buildings 3 in which the multiple elevators 2 narrowed down as command targets are installed. Thereafter, the processing of the management device 11 proceeds to step S06.

[0042] In step S06, the command unit 16 sets the highest rank as the target for command output. In this example, the command unit 16 sets rank 4 as the target for command output. Thereafter, the processing of the management device 11 proceeds to step S07.

[0043] In step S07, the command unit 16 outputs a command for the class set as the output target. The command unit 16 sequentially outputs a command to perform controlled operation for each of the command target elevators 2 installed in the building 3 for which the estimation result corresponds to that class. When the command target elevator 2 is selected as the representative elevator, the command unit 16 outputs, together with the command, a command to cause other elevators 2 in the same building 3 to perform controlled operation to that representative elevator. When priorities are set by the target management unit 15, the command unit 16 outputs commands to elevators 2 in order of highest priority. Thereafter, the processing of the management device 11 proceeds to step S08.

[0044] In step S08, the command unit 16 determines whether there is any elevator 2 for which the command output has failed. If there is any elevator 2 for which the command output has failed, the processing of the management device 11 proceeds to step S09. For example, the command unit 16 may determine that there is any elevator 2 for which the command output has failed when it is determined that the command output has also failed for elevators 2 installed in buildings 3 of a higher class than the class set as the output target. On the other hand, if there is no elevator 2 for which the command output has failed, the processing of the management device 11 proceeds to step S10. For example, even if there are elevators 2 for which the success or failure of the command output has not yet been determined, the command unit 16 may determine that there is no elevator 2 for which the command output has failed when there is no elevator 2 for which the command output has been determined to have failed.

[0045] In step S09, the command unit 16 re-outputs a command to the elevator 2 for which the command output failed. When the command output to the representative elevator fails, the command unit 16 may output a command to other elevators 2 installed in the same building 3. If there are multiple elevators 2 for which the command output failed, the command unit 16 re-outputs commands to these elevators 2 in sequence. At this time, the command unit 16 may re-output the commands in order of priority, or may re-output the commands in the order in which the command output failure was determined. After that, the processing of the management device 11 proceeds to step S08.

[0046] In step S10, the command unit 16 determines whether command output has been completed for all classes. If there are no elevators 2 for which command output has failed for a class set as an output target, the command unit 16 determines that command output for that class has been completed. If there are classes that have not yet been completed, the processing of the management device 11 proceeds to step S11. On the other hand, if command output for all classes has been completed, the processing of the management device 11 ends.

[0047] In step S11, the command unit 16 sets the next lower class as the command output target. For example, when class 4 is set as the command output target, the command unit 16 sets the next lower class 3 as the new command output target. Thereafter, the processing of the management device 11 proceeds to step S07.

[0048] As described above, the management device 11 for the elevator 2 according to the first embodiment includes the receiving unit 13, the estimating unit 14, the target management unit 15, and the command unit 16. The receiving unit 13 receives long-period ground motion data included in earthquake early warnings distributed by the external distribution agency 17. The estimating unit 14 estimates the class of long-period ground motion for each building 3. This estimation is performed based on building information stored in advance for each building 3 and the long-period ground motion data received by the receiving unit 13. The target management unit 15 narrows down the elevators 2 installed in each building 3 to elevators 2 to be commanded based on the class estimated by the estimating unit 14. The command unit 16 outputs a command to perform controlled operation during long-period vibration to the elevators 2 narrowed down as command targets by the target management unit 15.

[0049] With this configuration, the elevators 2 installed in buildings 3 estimated to be at a level requiring response are narrowed down as targets for command, and controlled operation commands are not output to other elevators 2. This suppresses unnecessary controlled operation, thereby preventing a decrease in elevator 2 operation efficiency. Long-period ground motion may also affect elevators 2 installed far from the epicenter. The management device 11 does not require that an Earthquake Early Warning be received in the building 3 in which the elevator 2 is installed as a condition for controlled operation. Therefore, even for buildings 3 that are not in an area where an Earthquake Early Warning is distributed, if the estimation result of the estimation unit 14 indicates a level requiring response, the command unit 16 can output a command to perform controlled operation to elevators 2 installed in the building 3. This makes it possible to more reliably respond to long-period ground motion.

[0050] Furthermore, the target management unit 15 sets priorities for the elevators 2 narrowed down as targets for commands based on the class estimated by the estimation unit 14. The command unit 16 outputs commands to elevators 2 with higher priorities set by the target management unit 15 earlier. Furthermore, the estimation unit 14 estimates the predicted arrival time of the long-period seismic motion for each building 3 based on the building 3 information and the long-period seismic motion data received by the receiving unit 13. The target management unit 15 sets priorities for the elevators 2 narrowed down as command targets based on the class and predicted arrival time estimated by the estimation unit 14. The command unit 16 outputs commands earlier to elevators 2 with higher priorities set by the target management unit 15.

[0051] With this configuration, a command for controlled operation is output more quickly to an elevator 2 that has a higher priority for response. This makes it possible to more reliably respond to long-period seismic motion through controlled operation.

[0052] Furthermore, there may be cases where a plurality of elevators 2 are installed in any one of the buildings 3, and the target management unit 15 targets each of the elevators 2 in the building 3 as a command target. In this case, the command unit 16 outputs a command to a representative elevator, which is one of the elevators 2 in the building 3, to cause the other elevators 2 in the building 3 to perform controlled operation, together with a command to perform controlled operation of the representative elevator.

[0053] This configuration reduces the total number of elevators 2 to which commands are directly output from the management device 11, thereby saving communication capacity for outputting commands from the management device 11 to each elevator 2. This can prevent communication congestion during disasters and also reduce communication costs.

[0054] Furthermore, if the command unit 16 fails to output a command to the representative elevator of a building 3, it selects an elevator 2 that is not the representative elevator from among the multiple elevators 2 in the building 3. The command unit 16 outputs to the selected elevator 2 a command to cause the other elevators 2 in the building 3, including the representative elevator, to perform controlled operation, together with a command to perform controlled operation of the selected elevator 2.

[0055] With this configuration, even if a communication failure occurs in the main elevator of a building 3, multiple elevators 2 in the building 3 can perform controlled operation. This makes it possible to more reliably respond to long-period seismic motion through controlled operation.

[0056] In addition, if the command unit 16 fails to output a command to an elevator 2 installed in a building 3 of a relatively high rank, it prioritizes re-outputting a command to that elevator 2 over outputting a command to an elevator 2 installed in a building 3 of a relatively low rank.

[0057] With this configuration, a controlled operation command can be output more quickly and reliably to elevators 2 installed in buildings 3 that are estimated to be more susceptible to long-period seismic motion. This allows for more effective response to long-period seismic motion through controlled operation.

[0058] Next, an example of the hardware configuration of the management system 1 will be described with reference to FIG. FIG. 3 is a hardware configuration diagram of the main part of the management system 1 according to the first embodiment.

[0059] Each function of the management system 1 may be realized by a processing circuit. The processing circuit includes at least one processor 100 a and at least one memory 100 b. The processing circuit may include at least one dedicated hardware 200 in addition to or in place of the processor 100 a and the memory 100 b.

[0060] When the processing circuit includes a processor 100a and a memory 100b, each function of the management system 1 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. The program is stored in the memory 100b. The processor 100a realizes each function of the management system 1 by reading and executing the program stored in the memory 100b. The program may be a program package including multiple subprograms, modules, libraries, or the like. The program may also be called a program product.

[0061] The processor 100a is also called a CPU (Central Processing Unit), processing device, arithmetic unit, microprocessor, microcomputer, or DSP. The memory 100b is configured by, for example, a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM.

[0062] Where the processing circuitry comprises dedicated hardware 200, the processing circuitry may be implemented, for example, as a single circuit, multiple circuits, a programmed processor, parallel programmed processors, an ASIC, an FPGA, or a combination thereof.

[0063] Each function of the management system 1 can be realized by a processing circuit. Alternatively, each function of the management system 1 can be realized collectively by a processing circuit. Some of the functions of the management system 1 may be realized by dedicated hardware 200, and other parts may be realized by software or firmware. In this way, the processing circuit realizes each function of the management system 1 by dedicated hardware 200, software, firmware, or a combination of these.
