Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration example of a monitoring system according to Embodiment 1 of the present invention. The monitoring system shown in FIG. 1 includes a monitoring device 1 and a plurality of elevator devices 2. The monitoring device 1 is connected to a plurality of elevator devices 2 via a network 3. The monitoring device 1 can communicate bidirectionally with the elevator device 2. The network 3 is, for example, a dedicated line. The network 3 may be an internet line. Both the dedicated line and the Internet line may be used as the network 3.

  For example, an elevator device 2 installed in various parts of Japan is connected to the monitoring device 1 by a network 3. Only the elevator apparatus 2 installed in some areas of Japan may be connected to the monitoring apparatus 1. For example, an elevator apparatus 2 installed only in East Japan is connected to the monitoring apparatus 1. Moreover, the elevator apparatus 2 installed in countries other than Japan may be connected to the monitoring apparatus 1 by the network 3. For example, an elevator device 2 installed in various places in China (CHINA) is connected to the monitoring device 1. In this case, the monitoring device 1 may be installed in China or may be installed in a country other than China. The elevator apparatus 2 installed in various parts of Japan and the elevator apparatus 2 installed in various parts of China may be connected to the monitoring apparatus 1.

  FIG. 2 is a diagram illustrating a configuration example of the elevator apparatus 2. The elevator apparatus 2 includes a car 4 and a counterweight 5. The car 4 and the counterweight 5 are suspended from the hoistway by the main rope 6. The hoisting machine 7 drives the car 4. The car 4 moves up and down the hoistway by being driven by the hoisting machine 7. The hoisting machine 7 is controlled by the control device 8.

  A control cable 9 is connected between the car 4 and the control device 8. Transmission / reception of signals between the devices provided in the car 4 and the control device 8 is performed via a control cable 9. The equipment provided in the car 4 is controlled by the control device 8. The equipment controlled by the control device 8 includes, for example, an electric motor for driving a door and a car operation panel.

  For example, the control device 8 controls a normal operation in which the car 4 sequentially responds to registered calls. The control device 8 controls the detection operation and the control operation. Details of the detection operation and the control operation will be described later.

  The elevator device 2 includes a detection device 10. The detection device 10 detects a shake of a long object used in the elevator device 2. Various long objects are used for the elevator apparatus 2. Examples of long objects used in the elevator apparatus 2 include ropes such as a main rope 6 and a compen- sion rope (not shown). Other examples of the long object used in the elevator apparatus 2 include cables such as the control cable 9. In the present embodiment, an example in which the detection device 10 detects the shake of the main rope 6 will be described in detail.

  The detection device 10 includes, for example, a light emitter and a light receiver. The light emitter emits light toward the light receiver. If the main rope 6 is not shaken, the light receiver receives light from the light emitter. When the main rope 6 is shaken with an amplitude greater than a specified value, the light from the light emitter strikes the main rope 6. This reduces the amount of light from the light emitter that the light receiver receives. Based on the amount of light received by the light receiver, it can be detected that the main rope 6 is shaken.

  The method by which the detection device 10 detects the shake of the main rope 6 is not limited to the above example. Further, the detection device 10 may detect the swing of the main rope 6 at a plurality of levels. The detection device 10 may detect vibrations at a plurality of locations of the main rope 6. The detection device 10 may detect a shake of another long object such as the control cable 9. The detection device 10 may detect shakes of a plurality of types of long objects. Note that not all elevator devices 2 that can communicate with the monitoring device 1 need include the detection device 10.

  The communication device 11 is a device for communicating with the outside. Signal transmission / reception between the elevator apparatus 2 and the outside is performed via the communication apparatus 11. For example, the elevator apparatus 2 communicates with the monitoring apparatus 1 through the communication apparatus 11.

  The monitoring device 1 includes, for example, an external information reception unit 12, a storage unit 13, a group selection unit 14, a device selection unit 15, a detection operation instruction unit 16, a control operation instruction unit 17, and a communication unit 18.

  The external information receiving unit 12 receives external information. The external information receiving unit 12 receives external information from a public organization such as the Japan Meteorological Agency. The external information receiving unit 12 may receive external information from a private organization.

  When an earthquake occurs, a building provided with the elevator apparatus 2 may continue to shake slowly over a long period of time, for example, at a primary natural frequency. Such shaking is not detected by ordinary seismic detectors because of its low acceleration. When the building is shaken, the long object used in the elevator apparatus 2 is shaken. For example, when the natural frequency of the main rope 6 matches the natural frequency of the building, the main rope 6 resonates. When the swing of the main rope 6 increases, the main rope 6 may come into contact with or be caught by equipment provided in the hoistway. For this reason, the external information receiving part 12 receives the information regarding an earthquake as external information, for example. The external information receiving unit 12 may receive earthquake information representing predicted values or measured values of seismic intensity in a plurality of areas as external information.

  If a strong wind blows when a typhoon is approaching, the building provided with the elevator apparatus 2 may continue to sway slowly over a long period of time, for example, at a primary natural frequency. For this reason, the external information receiving part 12 receives the information regarding a weather, for example as external information. The external information receiving unit 12 may receive weather information representing predicted wind speed values or measured values of a plurality of regions as external information.

  The external information received by the external information receiving unit 12 is not limited to earthquake information and weather information. The external information receiving unit 12 may receive other information as external information.

  The memory | storage part 13 memorize | stores the information of an elevator group. The storage unit 13 stores information on a plurality of elevator groups. Each elevator group in which the storage unit 13 stores information includes a plurality of elevator apparatuses 2. For example, the elevator group in which the storage unit 13 stores information includes all or a part of the elevator apparatus 2 with which the communication unit 18 can communicate. For example, of the elevator devices 2 with which the communication unit 18 can communicate, all elevator devices 2 in which the lifting / lowering stroke of the car 4 is greater than or equal to a reference value are included in at least one of the elevator groups in which the storage unit 13 stores information. May be. Table 1 shows an example of information stored in the storage unit 13.

  Table 1 shows an example in which an elevator group is set based on an area where the elevator apparatus 2 is installed. For example, an elevator group is set for each city where the elevator apparatus 2 is installed. For example, the elevator apparatus 2 provided in B city is included in the elevator group of group number 2.

  The setting method of the elevator group is not limited to the above example. For example, you may set the elevator apparatus 2 provided in the several municipalities to one elevator group. For example, you may set an elevator group according to the ground in which the building is provided. For example, you may set an elevator group according to the natural period of the building in which the elevator apparatus 2 is provided.

  The group selection unit 14 selects one or a plurality of elevator groups from a plurality of elevator groups for which the storage unit 13 stores information. The group selection unit 14 selects an elevator group based on the external information received by the external information reception unit 12.

  The device selection unit 15 selects one or a plurality of elevator devices 2 from among the plurality of elevator devices 2 included in the elevator group selected by the group selection unit 14. When the group selection unit 14 selects a plurality of elevator groups, the device selection unit 15 selects one or a plurality of elevator apparatuses 2 for each elevator group selected by the group selection unit 14. As an example, consider a case where the group selection unit 14 selects the elevator groups having the group numbers 1 and 2. The device selection unit 15 selects, for example, the elevator device 2 with the device number 00000010 from the elevator devices 2 included in the elevator group with the group number 1. Moreover, the apparatus selection part 15 selects the elevator apparatus 2 of the apparatus number 00001100 and the elevator apparatus 2 of the apparatus number 00001101 from the elevator apparatuses 2 included in the elevator group of the group number 2, for example.

  The detection operation instruction unit 16 causes the elevator device 2 selected by the device selection unit 15 to perform a detection operation. The detection operation is an operation for detecting a shake of a long object used in the elevator apparatus 2. Signal transmission / reception between the monitoring device 1 and the outside is performed via the communication unit 18. For example, the monitoring device 1 communicates with each elevator device 2 through the communication unit 18. The detection operation instruction unit 16 causes the communication unit 18 to transmit a signal for performing the detection operation. Hereinafter, a signal for performing the detection operation is also referred to as a “detection operation signal”. The detection operation signal is transmitted from the communication unit 18 to the elevator device 2 selected by the device selection unit 15.

  In the elevator device 2, when the communication device 11 receives the detection operation signal from the monitoring device 1, the control device 8 starts the detection operation. Further, when the detection device 10 detects the shake of the long object by performing the detection operation, the control device 8 causes the communication device 11 to transmit a signal indicating that the shake of the long object has been detected. Hereinafter, a signal indicating that the detection apparatus 10 has detected a shake of a long object is also referred to as a “shake detection signal”. The shake detection signal is transmitted from the communication device 11 to the monitoring device 1.

  The control operation instruction unit 17 causes the plurality of elevator apparatuses 2 included in the same elevator group as the elevator apparatus 2 in which the shake of the long object is detected to perform the control operation. The control operation is an operation for preventing the long object used in the elevator apparatus 2 from resonating with the shaking of the building. The control operation instruction unit 17 causes the communication unit 18 to transmit a signal for performing the control operation when the elevator apparatus 2 selected by the device selection unit 15 detects a shake of a long object. Hereinafter, a signal for performing the control operation is also referred to as a “control operation signal”. The control operation signal is transmitted from the communication unit 18 to the plurality of elevator apparatuses 2 included in the same elevator group as the elevator apparatus 2 in which the swing of the long object is detected. The control operation signal may be transmitted to all elevator apparatuses 2 included in the elevator group. The control operation signal may be transmitted to some elevator apparatuses 2 included in the elevator group.

  Next, an example of the operation performed by the monitoring system will be described with reference to FIG. FIG. 3 is a flowchart showing an operation example performed by the monitoring system according to Embodiment 1 of the present invention.

  In normal times, each elevator device 2 connected to the monitoring device 1 performs normal operation. The normal operation is controlled by the control device 8.

  In the monitoring device 1, the group selection unit 14 determines whether a start condition is satisfied (S101). The start condition is a condition for starting the detection operation in the elevator apparatus 2. For example, when the group selection unit 14 detects a situation in which a long object is likely to be shaken, the group selection unit 14 determines that the start condition is satisfied.

  For example, when an earthquake occurs, the external information receiving unit 12 receives earthquake information including measured values of seismic intensity at various locations. If there is an area where the measured value of the seismic intensity is greater than or equal to the reference value, the group selection unit 14 determines that the start condition is satisfied. In addition, the external information receiving unit 12 receives an earthquake early warning as earthquake information. The earthquake early warning includes predicted values of seismic intensity at each location. The group selection unit 14 may determine that the start condition is satisfied when there is an area where the predicted value of the seismic intensity is greater than or equal to the reference value. The reference value to be compared with the actually measured value or predicted value of the seismic intensity is stored in the storage unit 13 in advance.

  For example, the external information receiving unit 12 receives weather information including actual measurement values of wind speeds at various locations. The group selection unit 14 determines that the start condition is satisfied if there is an area where the actual measurement value of the wind speed is equal to or greater than the reference value. The external information receiving unit 12 receives weather information including predicted wind speed values at various locations when a typhoon is approaching. The group selection unit 14 may determine that the start condition is satisfied when there is an area where the predicted value of the wind speed is greater than or equal to the reference value. A reference value to be compared with the actual measured value or predicted value of the wind speed is stored in the storage unit 13 in advance.

  When the group selection unit 14 determines that the start condition is satisfied, the group selection unit 14 selects one or a plurality of elevator groups from among a plurality of elevator groups whose information is stored in the storage unit 13 (S102). For example, the group selection unit 14 selects an elevator group including the elevator apparatus 2 provided in an area where the measured value or predicted value of the seismic intensity is equal to or greater than the reference value. In this case, the group selection unit 14 selects one elevator group if there is one corresponding area. The group selection unit 14 selects a plurality of elevator groups if there are a plurality of corresponding areas. The group selection unit 14 includes an elevator group including the elevator apparatus 2 provided in an area where the measured value or predicted value of the seismic intensity is equal to or greater than a reference value, and an elevator group including the elevator apparatus 2 provided in an area adjacent to the area. May be selected.

  The group selection unit 14 may select an elevator group including the elevator apparatus 2 provided in an area where the measured value or predicted value of the wind speed is equal to or higher than the reference value. The group selection unit 14 includes an elevator group including the elevator apparatus 2 provided in an area where the measured value or predicted value of the wind speed is equal to or higher than a reference value, and an elevator group including the elevator apparatus 2 provided in an area adjacent to the area. May be selected.

  When the group selection unit 14 selects an elevator group, the device selection unit 15 selects one or a plurality of elevator devices 2 from among the plurality of elevator devices 2 included in the elevator group selected by the group selection unit 14 (S103). ). That is, the device selection unit 15 selects the elevator device 2 that performs the detection operation for each elevator group selected by the group selection unit 14.

  The elevator apparatus 2 selected by the apparatus selection unit 15 may be determined in advance. For example, when the group selection unit 14 selects the elevator group with the group number 1, the device selection unit 15 may always select the elevator device 2 with the device number 00000010. The elevator apparatus 2 selected by the apparatus selection unit 15 may not be determined in advance. For example, the device selection unit 15 may select the elevator device 2 in consideration of the external information received by the external information reception unit 12.

  When the device selection unit 15 selects the elevator device 2, the detection operation instruction unit 16 causes each elevator device 2 selected by the device selection unit 15 to perform a detection operation. Specifically, a detection operation signal is transmitted to each elevator device 2 selected by the device selection unit 15 (S104). In each elevator device 2 selected by the device selection unit 15, the communication device 11 receives the detection operation signal. Thereby, a detection operation is started in each elevator device 2 selected by the device selection unit 15. An example of the detection operation is shown below.

  When the communication device 11 receives the detection operation signal, the control device 8 moves the car 4 and stops it at the resonance floor. Among the long objects used in the elevator apparatus 2, there is one in which the length of the portion where the displacement is not constrained changes depending on the position of the car 4. In such a long object, the natural frequency of the portion where the displacement is not constrained varies depending on the position of the car 4. The resonance floor is a floor where long objects such as the main rope 6 are likely to resonate with the shaking of the building when the car 4 is stopped. The resonance floor is set in advance.

  The control device 8 operates the detection device 10 when the car 4 is stopped at the resonance floor. Accordingly, when a shake having an amplitude greater than or equal to a predetermined value is generated in the long object, the shake of the long object is detected by the detection device 10. In addition, the detection apparatus 10 may be operating before the car 4 stops on the resonance floor. When the detection device 10 detects a shake of a long object, the control device 8 causes the communication device 11 to transmit a shake detection signal. In the monitoring device 1, the communication unit 18 receives a shake detection signal.

  In the monitoring device 1, when the communication unit 18 transmits a detection operation signal in S104, the control operation instruction unit 17 determines whether or not the communication unit 18 has received the shake detection signal (S105). If the communication unit 18 has not received the shake detection signal, the monitoring device 1 continues the normal operation in each elevator device 2 (S106). The monitoring device 1 may cause the communication unit 18 to transmit a signal for performing normal operation as necessary.

  When the communication unit 18 receives the shake detection signal, the control operation instruction unit 17 causes the plurality of elevator devices 2 included in the same elevator group as the elevator device 2 in which the shake of the long object is detected to perform the control operation. Specifically, based on the received shake detection signal, the elevator apparatus 2 in which the shake of the long object is detected is specified. And a control operation signal is transmitted with respect to the several elevator apparatus 2 contained in the same elevator group as the elevator apparatus 2 (S107). In the plurality of elevator apparatuses 2 included in the same elevator group as the elevator apparatus 2 in which the shake of the long object is detected, the communication apparatus 11 receives the control operation signal. Thereby, the control operation is started in the plurality of elevator apparatuses 2. An example of control operation is shown below.

  When the communication device 11 receives the control operation signal, the control device 8 moves the car 4 and stops it at the non-resonant floor. The non-resonant floor is a floor where a long object such as the main rope 6 is unlikely to resonate with the shaking of the building even when the car 4 is stopped. The non-resonant floor is set in advance.

  The control device 8 may move the car 4 constantly or periodically when the communication device 11 receives the control operation signal. As described above, in the long object such as the main rope 6, the natural frequency of the portion where the displacement is not constrained varies depending on the position of the car 4. By moving the car 4, the natural frequency of the portion where the displacement is not constrained can be changed. For this reason, it is possible to prevent the long object from resonating with the shaking of the building.

  In the monitoring system configured as described above, the elevator group is selected based on the external information received by the external information receiving unit 12. Moreover, the elevator apparatus 2 which performs a detection operation is selected from the elevator apparatuses 2 included in the selected elevator group. For this reason, it can prevent that the operation efficiency of an elevator falls unnecessarily in many buildings. If it is the monitoring system of the said structure, when the shake of a long thing is detected by the elevator apparatus 2, the several elevator apparatus 2 contained in the same elevator group as the elevator apparatus 2 can be made to perform control operation. .

  In the monitoring system configured as described above, the group selection unit 14 selects an elevator group based on the external information received by the external information reception unit 12. For this reason, the elevator group can be dynamically selected. Elevator groups can be selected appropriately according to the occurrence of earthquakes and strong winds.

Below, the other method in which the group selection part 14 selects an elevator group is demonstrated.
When a large earthquake occurs, long-period ground motion occurs in areas far from the epicenter. Long-period ground motion is likely to occur in plains and basins covered with soft sedimentary layers. If you know the epicenter and magnitude of the earthquake, you can identify areas where long-period ground motion is likely to occur.

  For example, the external information receiving unit 12 receives earthquake information including the epicenter and magnitude of the earthquake. The magnitude of the earthquake included in the earthquake information may be an actual measurement value or a predicted value. In addition, the storage unit 13 stores the epicenter and magnitude of an earthquake and an area where a long-period ground motion is highly likely to occur when the earthquake occurs. For example, when the external information receiving unit 12 receives earthquake information whose magnitude of an earthquake is equal to or greater than a reference value, the group selecting unit 14 may generate long-period ground motion based on information stored in the storage unit 13. Identify high areas. That is, the group selection unit 14 specifies an area stored in association with the epicenter and magnitude of the earthquake included in the earthquake information. And the group selection part 14 selects the elevator group containing the elevator apparatus 2 provided in the specified area.

  When the communication device 11 receives the detection operation signal, it is stored in the storage unit 13 based on the earthquake information received by the external information reception unit 12 immediately before and the detection operation signal received by the communication device 11. Information may be updated.

  FIG. 4 is a diagram showing the strength and nature of long-period ground motion that occurs when a specific earthquake occurs. According to the speed response spectrum shown in FIG. 4 and the like, the elevator group may be set in advance based on the natural period of the building in which the elevator apparatus 2 is provided. For example, an elevator group in which the natural period of the building in which the elevator apparatus 2 is provided is 3 seconds to less than 5 seconds, an elevator group of 5 seconds to less than 7 seconds, an elevator group of 7 seconds to less than 10 seconds, and 10 seconds to 13 seconds Less than elevator groups are preset. The group selection unit 14 determines whether a specific earthquake has occurred based on the external information received by the external information reception unit 12. The group selection part 14 will select the elevator group set based on the natural period of a building, if the specific earthquake has generate | occur | produced.

  The selection of the elevator group based on the natural period of the building may be performed simultaneously with the selection of the elevator group based on another method. For example, one elevator apparatus 2 may be included in both an elevator group based on a natural period of a building and an elevator group based on another method.

  Also, strong winds that cause the building to shake are generated by typhoons and the like. For example, the external information receiving unit 12 receives weather information including an actual measurement value of wind speed. The external information receiving unit 12 may receive meteorological information including the wind direction and the measured value of wind speed, such as information issued from the Japan Meteorological Agency. FIG. 5 is a diagram showing an example of weather information issued from the Japan Meteorological Agency.

  Meteorological information is regularly issued by the Japan Meteorological Agency. For this reason, the weather information received by the external information receiving unit 12 may be stored in the storage unit 13 one by one as past information. When the communication unit 18 receives the detection operation signal, the information on the elevator apparatus 2 in which the shake of the long object is detected is associated with the weather information received by the external information reception unit 12 and stored in the storage unit 13. May be. In the storage unit 13, for example, time information, weather information received by the external information receiving unit 12, and information of the elevator apparatus 2 in which a shake of a long object is detected are associated and stored as past information.

  The group selection unit 14 calculates a predicted value of wind speed based on, for example, weather information newly received by the external information reception unit 12 and past information stored in the storage unit 13. The group selection unit 14 may select an elevator group based on the calculated predicted value. For example, the group selection unit 14 selects an elevator group including an elevator apparatus provided in an area where the calculated predicted value is equal to or greater than a reference value. For example, when a typhoon is approaching, it is possible to cause the elevator apparatus 2 to perform a detection operation before a situation in which a long object is likely to be shaken actually occurs.

Embodiment 2. FIG.
FIG. 6 is a diagram showing a configuration example of a monitoring system according to Embodiment 2 of the present invention. The monitoring device 1 in the present embodiment includes, for example, an external information reception unit 12, a storage unit 13, a group setting unit 19, a device selection unit 15, a detection operation instruction unit 16, a control operation instruction unit 17, and a communication unit 18.

  The storage unit 13 stores information on the elevator apparatus 2. Information of a plurality of elevator apparatuses 2 is stored in the storage unit 13. For example, the storage unit 13 stores information on all or a part of the elevator apparatuses 2 with which the communication unit 18 can communicate. The storage unit 13 may store information on all elevator apparatuses 2 in which the elevator 4 is moved up and down in the elevator apparatus 2 with which the communication unit 18 can communicate.

  The group setting unit 19 sets one or a plurality of elevator groups by combining a plurality of elevator apparatuses whose information is stored in the storage unit 13. The group setting unit 19 sets an elevator group based on the external information received by the external information receiving unit 12.

  The device selection unit 15 selects one or a plurality of elevator devices 2 from among the plurality of elevator devices 2 included in the elevator group set by the group setting unit 19. When the group setting unit 19 sets a plurality of elevator groups, the device selection unit 15 selects one or a plurality of elevator apparatuses 2 for each elevator group set by the group setting unit 19.

  Among the configurations and functions of the monitoring system, those not described in detail in the present embodiment are the same as any of the configurations and functions disclosed in the first embodiment.

  Next, an example of an operation performed by the monitoring system will be described with reference to FIG. FIG. 7 is a flowchart showing an operation example performed by the monitoring system according to Embodiment 2 of the present invention.

  In normal times, each elevator device 2 connected to the monitoring device 1 performs normal operation. The normal operation is controlled by the control device 8.

  In the monitoring device 1, the group setting unit 19 determines whether a start condition is satisfied (S201). For example, when the group setting unit 19 detects a situation in which a long object is likely to shake, the group setting unit 19 determines that the start condition is satisfied. For example, the external information receiving unit 12 receives earthquake information including actual measurement values or predicted values of seismic intensity at various locations. If there is an area where the measured value or predicted value of the seismic intensity is greater than or equal to the reference value, the group setting unit 19 determines that the start condition is satisfied. The external information receiving unit 12 receives weather information including actual measured values or predicted values of wind speeds in various locations. The group setting unit 19 may determine that the start condition is satisfied when there is an area where the actual measurement value or the predicted value of the wind speed is equal to or greater than the reference value.

  When determining that the start condition is satisfied, the group setting unit 19 sets an elevator group (S202). Each elevator group set by the group setting unit 19 includes a plurality of elevator apparatuses 2. The group setting unit 19 sets one or a plurality of elevator groups by combining the elevator apparatuses 2 whose information is stored in the storage unit 13. Table 2 shows an example of information stored in the storage unit 13.

  Even the monitoring system having the above-described configuration can achieve the same effects as the monitoring system disclosed in the first embodiment. If it is the monitoring system shown in this Embodiment, an elevator group can be appropriately set according to the external information which the external information receiving part 12 received.

  In addition, the storage unit 13 may store the epicenter and magnitude of an earthquake and an area where a long-period ground motion is highly likely to occur when the earthquake occurs. For example, when the external information receiving unit 12 receives earthquake information whose magnitude of the earthquake is greater than or equal to a reference value, the group setting unit 19 may generate long-period ground motion based on the information stored in the storage unit 13. Identify high areas. That is, the group setting unit 19 specifies an area stored in association with the epicenter and magnitude of the earthquake included in the earthquake information. And the group setting part 19 sets the elevator group containing the elevator apparatus 2 provided in the specified area.

  When the communication device 11 receives the detection operation signal, it is stored in the storage unit 13 based on the earthquake information received by the external information reception unit 12 immediately before and the detection operation signal received by the communication device 11. Information may be updated.

  The group setting unit 19 may set the elevator group based on the epicenter and magnitude of the earthquake and the natural period of the building where the elevator apparatus 2 is provided. The setting of the elevator group based on the natural period of the building may be performed simultaneously with the setting of the elevator group based on another method.

  Weather information received by the external information receiving unit 12 may be stored in the storage unit 13 one by one as past information. When the communication unit 18 receives the detection operation signal, the information on the elevator apparatus 2 in which the shake of the long object is detected is associated with the weather information received by the external information reception unit 12 and stored in the storage unit 13. May be. In the storage unit 13, for example, time information, weather information received by the external information receiving unit 12, and information of the elevator apparatus 2 in which a shake of a long object is detected are associated and stored as past information.

  The group setting unit 19 calculates a wind speed prediction value based on, for example, weather information newly received by the external information receiving unit 12 and past information stored in the storage unit 13. The group setting unit 19 may set an elevator group based on the calculated predicted value. For example, if a plurality of areas where the calculated predicted values are equal to or greater than the reference value are adjacent to each other, the group setting unit 19 sets the elevator apparatus 2 provided in those areas as one elevator group.

  In each embodiment, the example in which the elevator apparatus 2 includes one car 4 has been described. The elevator apparatus 2 may include a plurality of cars 4. In this case, the elevator apparatus 2 may include a group management apparatus that manages a plurality of cars 4 as a group.
