Embodiment 1.
FIG. 1 is a diagram showing an example of a determination system according to Embodiment 1. FIG. The determination system shown in FIG. 1 includes a plurality of elevator devices 1 and an information center 2. As shown in FIG. Each elevator device 1 is capable of two-way communication with the information center 2 .

The elevator device 1 includes, for example, a car 3 and a counterweight 4 . The car 3 moves up and down in the hoistway 5 . A counterweight 4 moves up and down the hoistway 5 . The car 3 and counterweight 4 are suspended in the hoistway 5 by main ropes 6 .

A main rope 6 is wound around a hoist 7 . The car 3 is driven by a hoist 7 . The hoist 7 is controlled by a control device 8 . FIG. 1 shows an example in which the hoist 7 and the control device 8 are installed in a machine room 9 above the hoistway 5 . The hoisting machine 7 and the control device 8 may be installed in the hoistway 5 . When the hoisting machine 7 is installed in the hoistway 5 , the hoisting machine 7 may be installed at the top of the hoistway 5 or may be installed in the pit of the hoistway 5 .

A communication device 10 is connected to the control device 8 . The communication device 10 is a device for the elevator device 1 to communicate with the outside. Communication between the elevator device 1 and the information center 2 is performed via the communication device 10 . Any method may be used for the communication device 10 to communicate with the information center 2 . The communication device 10 communicates with the information center 2 via a specific network. The specific network may be an IP network. An IP network is a communication network using IP (Internet Protocol) as a communication protocol.

The car 3 has an intercom 11 and a camera 12 . The intercom 11 is a device for a person in the car 3 to talk with an operator 13 in the information center 2.例文帳に追加A camera 12 photographs the inside of the car 3 . Images captured by the camera 12 are transmitted to the information center 2 via the communication device 10 . The operator 13 can check the image captured by the camera 12 on the terminal 14 .

An accelerometer 15 is provided in the building in which the elevator device 1 is provided. FIG. 1 shows an example where the accelerometer 15 is installed in the machine room 9 . The installation location of the accelerometer 15 does not have to be the machine room 9 . Accelerometer 15 detects the acceleration of the building. Acceleration data detected by the accelerometer 15 is transmitted to the information center 2 via the communication device 10 .

FIG. 2 is a flowchart showing an operation example of the elevator device 1. FIG. In the elevator device 1, it is determined whether or not an earthquake has occurred (S101). If no earthquake has occurred, the control device 8 performs normal operation (S102). In normal operation, controller 8 causes cars 3 to respond sequentially to registered calls.

As mentioned above, building acceleration is detected by the accelerometer 15 . If the accelerometer 15 detects acceleration greater than the first reference value, the determination in S101 is Yes. If determined as Yes in S101, the control device 8 stops normal operation. After stopping the normal operation, the control device 8 starts the earthquake control operation (S103). In the earthquake control operation, the car 3 stops at the nearest floor. When the car 3 stops at the nearest floor, the doors are opened and closed. This allows the passengers to get off the car 3.

If the passenger is confined in the car 3 because of some reason, the control operation during an earthquake does not end normally, a confinement signal is transmitted from the communication device 10 to the information center 2 . The confinement signal includes, for example, information for identifying the elevator system 1, information indicating that confinement has occurred, and acceleration data from the accelerometer 15. FIG. In the following, the information for specifying the elevator device 1 is also referred to as identification information.

When the earthquake control operation ends normally, it is determined whether or not a specific return condition is satisfied (S104). A return condition is set in advance. For example, if the acceleration detected by the accelerometer 15 is smaller than the second reference value, the determination in S104 is Yes. The second reference value is a value greater than the first reference value. If determined as Yes in S104, the control device 8 resumes normal operation (S102).

If it is determined No in S104, it is determined whether or not a specific diagnostic condition is satisfied (S105). Diagnosis conditions are set in advance. For example, if the acceleration detected by the accelerometer 15 is greater than the third reference value, it is determined No in S105. The third reference value is a value greater than the second reference value. If determined as No in S105, the control device 8 stops the elevator (S106).

If the elevator is parked at S106, then there are no passengers trapped in car three. Further, when the elevator is stopped in S106, restoration work on site by maintenance personnel is required in order to resume normal operation. Therefore, when the elevator stops in S106, the communication device 10 transmits a restoration request signal to the information center 2. FIG. The recovery request signal includes, for example, identification information of the elevator device 1, information indicating that the elevator has stopped, and acceleration data from the accelerometer 15. FIG.

On the other hand, if the acceleration detected by the accelerometer 15 is greater than the second reference value and less than the third reference value, the determination in S105 is Yes. If determined as Yes in S105, the control device 8 starts diagnostic operation (S107). In diagnostic operation, various data are measured to determine whether there is an abnormality.

When the diagnostic operation is started, it is determined whether or not a specific provisional return condition is satisfied (S108). A temporary return condition is set in advance. For example, if an abnormality is detected based on the data measured during diagnostic operation, the determination in S108 is No. If determined as No in S108, the control device 8 stops the elevator (S106). Further, when the elevator stops in S106, the communication device 10 transmits the restoration request signal to the information center 2. FIG.

If no abnormality is detected based on the data measured during diagnostic operation, the determination in S108 is Yes. If determined as Yes in S108, the control device 8 temporarily restores the elevator (S109). In S109, the control device 8 starts operation similar to normal operation. In S109, the control device 8 may start operation with some of the functions performed in normal operation limited.

In order to restore the elevator completely after S109, on-site confirmation work by maintenance personnel is required. Therefore, when the elevator is temporarily restored in S<b>109 , a temporary restoration signal is transmitted from the communication device 10 to the information center 2 . The temporary restoration signal includes, for example, identification information of the elevator device 1, information indicating that the elevator has been temporarily restored, and acceleration data from the accelerometer 15. FIG.

The acceleration data detected by the accelerometer 15 may be transmitted from the communication device 10 to the information center 2 immediately after an earthquake occurs. For example, when it is determined as Yes in S101, an earthquake signal is transmitted from the communication device 10 to the information center 2. FIG. This seismic signal includes identification information of the elevator device 1 and acceleration data from the accelerometer 15 .

The information center 2 is further equipped with a determination device 16 in addition to the terminal 14 . FIG. 3 is a diagram showing an example of the determination device 16. As shown in FIG. The judgment device 16 has a function of making a judgment for efficient recovery, including the elevator device 1 that is not confined, when a wide-area earthquake or the like occurs. For example, when a wide-area earthquake occurs, the determination device 16 uses all or part of the information indicated by I1 to I7 to determine the priority for dispatching maintenance personnel. The decision device 16 may also use other information for the priority decision.
I1: Presence or absence of confinement I2: Attributes and conditions of confined persons (children, old people, people with disabilities, people in poor physical condition, etc.)
I3: Presence or absence of installation of a disaster prevention equipment box in the car I4: Use of the building I5: Intensity of shaking generated in the building I6: Seismic standards for elevator equipment I7: Ground amplification factor

In order to implement such functions, the determination device 16 includes a storage unit 20 , an identification unit 21 , an acquisition unit 22 , a division unit 23 , a determination unit 24 , an analysis unit 25 and a calculation unit 26 . A management table is stored in the storage unit 20 . Table 1 shows an example of a management table stored in the storage unit 20.

In the example shown in Table 1, identification information of each elevator device 1 managed by the information center 2 is registered in the management table. The elevator devices 1 managed by the information center 2 include all elevator devices 1 that can communicate with the information center 2 .

In the management table, for each elevator device 1 managed by the information center 2, seismic strength information of the elevator device 1 and building information about the building in which the elevator device 1 is installed are registered in association with the identification information. be done. Table 1 shows an example in which the building information includes the use of the building and the natural frequency of the building. Information other than the information shown in Table 1 may be included in the building information. The functions of this determination system will be described in detail below with reference to FIG. 4 as well.

FIG. 4 is a flow chart showing an operation example of the determination device 16 . When a wide-area earthquake or the like occurs, the identification unit 21 identifies elevator devices 1 that require dispatch of maintenance personnel from among the elevator devices 1 managed by the information center 2 (S201).

Elevator systems 1 requiring dispatch of maintenance personnel include all elevator systems 1 in which confinement occurs. For example, the acquisition unit 22 acquires a confinement signal from the elevator device 1 . The elevator apparatus 1 that has transmitted the lock-in signal is identified by the identification unit 21 as an elevator apparatus 1 that requires dispatch of maintenance personnel.

Elevator systems 1 requiring dispatch of maintenance personnel include elevator systems 1 in which no confinement has occurred. For example, the acquisition unit 22 acquires a restoration request signal from the elevator device 1 . The elevator device 1 that has transmitted the restoration request signal is identified by the identification unit 21 as the elevator device 1 that requires the dispatch of maintenance personnel. As another example, the acquisition unit 22 acquires the temporary restoration signal from the elevator device 1 . The elevator device 1 that has transmitted the temporary restoration signal is identified by the identification unit 21 as the elevator device 1 that requires the dispatch of maintenance personnel.

Incidentally, when a certain elevator device 1 is trapped, a passenger trapped in the car 3 contacts the operator 13 via the intercom 11 . The operator 13 operates the terminal 14 to input information indicating that the elevator apparatus 1 is being confined. Acquisition unit 22 acquires information input from terminal 14 . The specifying unit 21 may specify the elevator device 1 as the elevator device 1 requiring dispatch of maintenance personnel based on the input information from the terminal 14 acquired by the acquiring unit 22 .

Moreover, the series of operations shown in FIG. 2 are not performed in all the elevator apparatuses 1 . For example, some elevator devices 1 do not have an automatic diagnosis function after an earthquake. When such an elevator system 1 stops due to an earthquake, the building manager contacts the operator 13 by telephone or the like. The operator 13 operates the terminal 14 to input information indicating that the elevator apparatus 1 is at rest. The specifying unit 21 may specify the elevator device 1 as the elevator device 1 requiring dispatch of maintenance personnel based on the input information from the terminal 14 acquired by the acquiring unit 22 .

The dividing unit 23 divides the elevator apparatuses 1 identified by the identifying unit 21 in S202 into a plurality of groups. First, the dividing unit 23 divides the elevator apparatuses 1 specified by the specifying unit 21 into an A group in which confinement occurs and a B group in which confinement does not occur (S202).

The determination unit 24 determines the priority for dispatching maintenance personnel for the elevator apparatus 1 that requires dispatch of maintenance personnel. The determining unit 24 determines the priority for each group divided by the dividing unit 23 . For example, the determination unit 24 determines the priority so that the elevator apparatus 1 included in the A group has priority over the elevator apparatus 1 included in the B group in dispatching maintenance personnel. For a specific group, the determination unit 24 may determine the priority of each elevator device 1 included in the group.

For example, the determination unit 24 determines the priority based on the registration information registered in the management table and the acquisition information acquired by the acquisition unit 22 . The registration information includes at least building information. The acquired information includes at least acceleration data from the accelerometer 15 . The acquisition unit 22 is configured to acquire acceleration data from the accelerometers 15 provided in each building whose building information is registered in the management table.

In the example shown in FIG. 4, the elevator apparatuses 1 included in the A group are further divided into the C group and the D group by the dividing unit 23 (S203). Group C includes only elevator devices 1 whose building use is a hospital. The D group includes elevator apparatuses 1 that cannot be included in the C group among the elevator apparatuses 1 included in the A group. That is, the D group includes the elevator apparatus 1 whose building use is not a hospital.

As another example, Group C may further include an elevator apparatus 1 whose building is a public facility. In this case, Group D includes elevator devices 1 whose building use is not hospitals or public facilities. The determination unit 24 determines the priority so that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the C group over the elevator devices 1 included in the D group (S204).

For example, the determination unit 24 determines the highest priority P1 for the elevator devices 1 included in the C group. That is, the highest priority is given to dispatching maintenance personnel to the elevator devices 1 included in the C group among the elevator devices 1 requiring dispatch of maintenance personnel.

The determination unit 24 determines priority P2, which is lower than priority P1, for the elevator devices 1 included in the D group. By dividing the elevator devices 1 included in the D group into smaller groups, the determination unit 24 may determine the priority for each group. As described above, the determination unit 24 may determine the priority of each of the elevator devices 1 included in the D group.

For example, an image captured by the camera 12 is transmitted from the elevator device 1 in which confinement has occurred to the information center 2 . The analysis unit 25 analyzes the image transmitted from the elevator device 1 and identifies the attribute and state of the trapped person. The determination unit 24 may determine the priority based on the result specified by the analysis unit 25 .

As an example, the elevator devices 1 included in the D group are divided into a D1 group in which a specific person is confined and a D2 group in which a person other than the specific person is confined. The specified persons include persons with disabilities and persons with poor physical condition. The specific person may further include children and the elderly. In S204, the determination unit 24 determines the priority so that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the D1 group over the elevator devices 1 included in the D2 group.

As another example, the calculator 26 calculates the value V indicating the strength of the shaking that occurred in the building for each of the elevator devices 1 included in the D group. The value V is calculated from a specific formula based on the natural frequency of the building registered in the management table and the acceleration data acquired by the acquisition unit 22 . The above calculation formula is set in advance. In calculating the value V, the seismic strength information registered in the management table may be further used. Similarly, in calculating the value V, the ground amplification factor of the area where the building is located may also be used. For example, a coefficient corresponding to the seismic strength information or a coefficient corresponding to the ground amplification factor is substituted into the above calculation formula.

In this example, the elevator devices 1 included in the D group are divided into a D1 group in which the value V exceeds the specified value V1 and a D2 group in which the value V does not exceed the specified value V1. The specified value V1 is set in advance. In S204, the determination unit 24 determines the priority so that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the D1 group over the elevator devices 1 included in the D2 group.

As another example, the calculation unit 26 may calculate the value W indicating the degree of resonance phenomenon occurring in the building for each of the elevator devices 1 included in the D group. In general, the more the natural period of the building and the natural period of the earthquake become equal, the more the shaking of the building is amplified. Such a phenomenon is called a resonance phenomenon. For example, the greater the resonance phenomenon occurring in the building, the greater the value W. The value W is calculated from a specific formula based on the natural frequency of the building registered in the management table and the acceleration data acquired by the acquisition unit 22 . The above calculation formula is set in advance. In calculating the value W, seismic strength information registered in the management table may be further used. Similarly, in calculating the value W, the ground amplification factor of the area where the building is located may also be used. For example, a coefficient corresponding to the seismic strength information or a coefficient corresponding to the ground amplification factor is substituted into the above calculation formula.

In this example, the elevator apparatuses 1 included in the D group are divided into a D1 group in which the value W exceeds the specified value W1 and a D2 group in which the value W does not exceed the specified value W1. The prescribed value W1 is set in advance. In S204, the determination unit 24 determines the priority so that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the D1 group over the elevator devices 1 included in the D2 group.

On the other hand, the elevator apparatuses 1 included in the B group are further divided into the E group and the F group by the dividing unit 23 (S205). Group E includes only elevator installations 1 whose building use is a hospital. The F group includes elevator apparatuses 1 that cannot be included in the E group among the elevator apparatuses 1 included in the B group. That is, the F group includes the elevator apparatus 1 whose building use is not a hospital.

As another example, the E group may further include the elevator apparatus 1 whose building is a public facility. In such a case, Group F includes elevator installations 1 whose building use is not hospitals or public facilities. The determination unit 24 determines the priority so that the elevator apparatus 1 included in the E group has higher priority in dispatching maintenance personnel than the elevator apparatus 1 included in the F group (S206).

For example, the determination unit 24 determines the priority P3, which is lower than the priorities P1 and P2, for the elevator devices 1 included in the E group. The priority P3 is the highest priority among the priorities determined for the elevator apparatuses 1 included in the B group.

The determination unit 24 determines the priority P4 lower than the priority P3 for the elevator devices 1 included in the F group. By dividing the elevator apparatuses 1 included in the F group into smaller groups, the determination unit 24 may determine the priority for each group. As described above, the determination unit 24 may determine the priority for each of the elevator devices 1 included in the F group.

As an example, the calculation unit 26 calculates the value V indicating the strength of the shaking that occurred in the building for each of the elevator devices 1 included in the F group. As described above, the value V is calculated from a specific formula based on the natural frequency of the building registered in the management table and the acceleration data acquired by the acquisition unit 22 . In calculating the value V, the seismic strength information registered in the management table may be further used. Similarly, in calculating the value V, the ground amplification factor of the area where the building is located may also be used.

In this example, the elevator devices 1 included in the F group are divided into the F1 group in which the value V exceeds the specified value V2 and the F2 group in which the value V does not exceed the specified value V2. The specified value V2 is set in advance. In S206, the determination unit 24 determines the priority such that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the F1 group over the elevator devices 1 included in the F2 group.

As another example, the calculation unit 26 may calculate the value W indicating the degree of resonance phenomenon occurring in the building for each of the elevator devices 1 included in the F group. The value W is calculated from a specific formula based on the natural frequency of the building registered in the management table and the acceleration data acquired by the acquisition unit 22 . In calculating the value W, seismic strength information registered in the management table may be further used. Similarly, in calculating the value W, the ground amplification factor of the area where the building is located may also be used. For example, a coefficient corresponding to the seismic strength information or a coefficient corresponding to the ground amplification factor is substituted into the above calculation formula.

In this example, the elevator apparatuses 1 included in the F group are divided into an F1 group in which the value W exceeds the specified value W2 and an F2 group in which the value W does not exceed the specified value W2. The specified value W2 is set in advance. In S204, the determination unit 24 determines the priority so that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the F1 group over the elevator devices 1 included in the F2 group.

The specified value V2 may be the same value as the specified value V1. In this case, the determination unit 24 determines the priority of the elevator devices 1 included in the F group based on the same criteria as the priority determination criteria for the elevator devices 1 included in the D group.

Similarly, the specified value W2 may be the same value as the specified value W1. In this case, the determination unit 24 determines the priority of the elevator devices 1 included in the F group based on the same criteria as the priority determination criteria for the elevator devices 1 included in the D group.

It should be noted that the elevator apparatus 1 included in the D group is confined. On the other hand, the elevator apparatus 1 included in the F group is not confined. Therefore, the determination unit 24 may determine the priority of the elevator devices 1 included in the F group based on a criterion different from the criteria for determining the priority of the elevator devices 1 included in the D group. For example, in S206, the determination unit 24 may determine the priority such that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the F2 group over the elevator devices 1 included in the F1 group. In this example, it is possible to preferentially dispatch maintenance personnel to the elevator device 1 that can be quickly restored.

As another example, the dividing unit 23 may divide the elevator apparatuses 1 included in the F group into smaller groups according to the presence or absence of the temporary restoration signal. For example, the elevator apparatuses 1 included in the F group are divided into the F1 group from which the acquisition unit 22 has acquired the temporary restoration signal and the F2 group from which the acquisition unit 22 has not acquired the temporary restoration signal. That is, the F1 group includes only the elevator device 1 to which the temporary restoration signal has been transmitted from the communication device 10 .

The provisional restoration signal indicates that no abnormality was detected in the post-earthquake diagnostic operation. Therefore, the temporarily restored elevator apparatus 1 operates to respond to the registered call. In this example, the determination unit 24 preferably determines the priority so that the dispatch of maintenance personnel is prioritized for the elevator devices 1 included in the F2 group over the elevator devices 1 included in the F1 group. The determination unit 24 may determine the priority based on the value V calculated by the calculation unit 26 for the elevator devices 1 included in the F2 group. The determination unit 24 may determine the priority based on the value W calculated by the calculation unit 26 for the elevator devices 1 included in the F2 group.

As described above, in the example shown in the present embodiment, the elevator apparatuses 1 requiring the dispatch of maintenance personnel are divided into the A group in which confinement occurs and the B group in which confinement does not occur. Then, for the elevator devices 1 included in the B group, the priority for dispatching maintenance personnel is determined based on the building information registered in the management table and the acceleration data acquired by the acquisition unit 22 . Therefore, in the example shown in the present embodiment, when a wide-area earthquake or the like occurs, it is possible to make a determination for efficient recovery, including the elevator device 1 in which confinement has not occurred. .

The number of elevator apparatuses 1 included in the A group is often smaller than the number of elevator apparatuses 1 included in the B group. When the number of elevator devices 1 included in the A group is extremely small, the determination unit 24 may determine one priority P1 for the elevator devices 1 included in the A group.

In the present embodiment, each part indicated by reference numerals 20 to 26 indicates the function of the determination device 16. FIG. FIG. 5 is a diagram showing an example of hardware resources of the determination device 16. As shown in FIG.

The determination device 16 implements the functions of the units indicated by reference numerals 21 to 26 by causing the processor 31 to execute the programs stored in the memory 32 . A semiconductor memory or the like can be used as the memory 32 .

In the example shown in FIG. 6, the determination device 16 comprises processing circuitry 30 including, for example, a processor 31 , a memory 32 and dedicated hardware 33 . FIG. 6 shows an example in which a part of the functions of the determination device 16 are implemented by dedicated hardware 33 . All the functions of the determination device 16 may be implemented by dedicated hardware 33 .
