As a technique related to the control operation of an elevator during an earthquake, for example, there is one described in Patent Document 1 below.

Japanese Unexamined Patent Publication No. 2006-160449

The output of a conventional seismic detector is, for example, a simple contact signal indicating that the acceleration due to shaking has exceeded a reference value. For this reason, the conventional earthquake detector is difficult to use when trying to expand the service of the elevator in the event of an earthquake.

The present invention has been made to solve the above problems. The object is to provide an elevator earthquake sensor that can expand the service of the elevator in the event of an earthquake.

The earthquake detector for an elevator according to the present invention has a function of performing bidirectional communication between an acceleration detection unit that detects a swing as an acceleration and an elevator control panel, and indicates the maximum acceleration detected by the acceleration detection unit. And a communication unit that transmits numerical values to the control panel.

In the present invention, the communication unit has a function of performing bidirectional communication with the control panel of the elevator, and transmits a numerical value indicating the maximum acceleration detected by the acceleration detection unit to the control panel. For this reason, according to this invention, the service of the elevator at the time of the occurrence of an earthquake can be expanded.

It is a figure for demonstrating restoration of the elevator after the occurrence of an earthquake. 3 is a flowchart illustrating an operation example of the elevator automatic recovery system according to the first embodiment. It is a hardware block diagram of a maintenance apparatus.

Referring to the attached drawings, the earthquake detector for elevators and the elevator automatic recovery system will be explained in detail. In each figure, the same or corresponding parts are denoted by the same reference numerals. The overlapping description will be simplified or omitted as appropriate.

Embodiment 1 FIG.
Drawing 1 is a mimetic diagram showing an example of the structure of an elevator.

As shown in FIG. 1, the elevator 1 includes a hoistway 2, a hoisting machine 3, a rope 4, a car 5, a counterweight 6, a control panel 7, and an earthquake detector 8. The hoistway 2 is formed, for example, so as to penetrate each floor of a building (not shown). The hoisting machine 3 is provided, for example, in a machine room (not shown). The rope 4 is wound around the hoisting machine 3. The car 5 and the counterweight 6 are suspended in the hoistway 2 by the rope 4. The car 5 and the counterweight 6 move up and down when the hoisting machine 3 is driven. The hoisting machine 3 is controlled by the control panel 7.

As shown in FIG. 1, the control panel 7 and the earthquake detector 8 are provided in the hoistway 2, for example. The control panel 7 and the earthquake detector 8 are provided in a pit, for example. The control panel 7 and the earthquake detector 8 may be provided in a machine room, for example. The earthquake sensor 8 is electrically connected to the control panel 7.

The control panel 7 is electrically connected to the hoisting machine 3 and the maintenance device 9. The maintenance device 9 has a function of communicating with the monitoring center 10. That is, the control panel 7 can communicate with the monitoring center 10 via the maintenance device 9.

The control panel 7 and the maintenance device 9 are provided, for example, in a building where the elevator 1 is installed. The monitoring center 10 is provided in a building different from the building where the elevator 1 is installed, for example. The monitoring center 10 is, for example, a server provided in a management company for the elevator 1.

The monitoring center 10 may be able to communicate with the control panels 7 of the plurality of elevators 1, for example. For example, the monitoring center 10 may be able to communicate with a plurality of maintenance apparatuses 9 provided in different buildings.

FIG. 2 is a functional block diagram of the elevator automatic recovery system according to the first embodiment.

As shown in FIG. 2, the control panel 7 has an operation control unit 11. The earthquake detector 8 includes a communication unit 12, an acceleration detection unit 13, a shaking direction detection unit 14, a shaking time detection unit 15, and a self-diagnosis unit 16. The maintenance device 9 includes a sensor control unit 17, an automatic diagnosis control unit 18, a storage unit 19, and a notification unit 20. The monitoring center 10 includes a storage unit 21 and an update unit 22.

The operation control unit 11 controls the operation of the elevator 1. For example, the operation control unit 11 controls the movement of the car 5 by controlling the driving of the hoisting machine 3. The operation control unit 11 controls the opening / closing of the door of the elevator 1 via, for example, a door opening / closing device (not shown).

The communication unit 12 communicates with the control panel 7. The signal transmitted and received between the communication unit 12 and the control panel 7 is not a contact signal, for example. A transmission method between the communication unit 12 and the control panel 7 is, for example, serial transmission. The communication unit 12 transmits information to the control panel 7. The communication unit 12 receives information from the control panel 7. That is, the earthquake detector 8 has a function of performing bidirectional communication with the control panel 7. Further, the earthquake detector 8 has a function of performing bidirectional communication with the maintenance device 9 via the control panel 7.

The acceleration detection unit 13 detects a shake due to an earthquake or the like as an acceleration. For example, the acceleration detector 13 constantly detects acceleration. The acceleration is expressed by, for example, a Gal value.

The shaking direction detector 14 detects the acceleration for each shaking direction. The shaking direction includes, for example, a horizontal direction and a vertical direction. For example, directions corresponding to the X axis, the Y axis, and the Z axis that are orthogonal to each other may be set as the shaking direction. As the horizontal direction among the shaking directions, for example, directions corresponding to four directions or eight directions may be set. The horizontal direction among the shaking directions may be set according to the planar shape of the building, for example. For example, the shaking direction detection unit 14 always detects acceleration in each shaking direction. The acceleration for each shaking direction is represented by, for example, a Gal value associated with the direction.

The shaking direction detection unit 14 may calculate the acceleration for each shaking direction by, for example, decomposing the acceleration detected by the acceleration detection unit 13. For example, the shaking direction detection unit 14 may detect the acceleration for each shaking direction using a plurality of sensors corresponding to each of the shaking directions. *

The shaking time detector 15 detects the shaking time. The shaking time is, for example, a time during which shaking at an acceleration exceeding a preset threshold value continues. The shaking time is, for example, the time when acceleration exceeding the threshold is continuously detected by the acceleration detector 13. For example, when the interval from the end time of the first shake time to the start time of the second shake time is less than a certain time, the shake time detection unit 15 performs the second change from the start time of the first shake time to the second time. The time until the end of the shaking time may be detected as one continuous shaking time. The shaking time is expressed in seconds or minutes, for example.

The communication unit 12 transmits, for example, various numerical values detected by the acceleration detection unit 13, the shaking direction detection unit 14, and the shaking time detection unit 15 to the control panel 7. The communication unit 12 transmits various numerical values when, for example, an acceleration exceeding a threshold is detected by the acceleration detection unit 13. For example, the control panel 7 transmits various numerical values to the maintenance device 9.

The communication unit 12 transmits a numerical value indicating the maximum acceleration detected by the acceleration detection unit 13, for example. The communication part 12 transmits the numerical value which shows the maximum acceleration for every shaking direction detected by the shaking direction detection part 14, for example. For example, the communication unit 12 transmits a numerical value indicating the maximum shaking time detected by the shaking time detection unit 15. In this way, the earthquake detector 8 detects shaking as acceleration, and outputs a numerical value based on the detected acceleration.

The maximum acceleration is, for example, the maximum value of the acceleration detected by the acceleration detection unit 13 during the period from when the acceleration detected by the acceleration detection unit 13 exceeds the threshold value to below the threshold value. The maximum acceleration for each shaking direction is, for example, the maximum value of acceleration detected by the shaking direction detection unit 14 during the period.

The sensor control unit 17 transmits a reset signal to the earthquake sensor 8, for example. For example, when the earthquake sensor 8 receives a reset signal, the earthquake sensor 8 stops outputting numerical values based on the acceleration.

For example, the detector control unit 17 periodically checks the life and death of the earthquake detector 8. For example, the sensor control unit 17 transmits a request signal to the earthquake sensor 8. The communication unit 12 returns a response signal to the request signal, for example. For example, when the response signal is received within a predetermined time after transmitting the request signal, the sensor control unit 17 determines that the earthquake sensor 8 is operating. For example, when the sensor control unit 17 does not receive a response signal within a predetermined time after transmitting a request signal, the seismic sensor 8 is not operating or the connection between the control panel 7 and the seismic sensor 8 is disconnected. It is determined that

The sensor control unit 17 transmits a function diagnosis command to the earthquake sensor 8, for example. For example, the self-diagnosis unit 16 performs a diagnosis operation based on a function diagnosis command. The diagnostic operation is, for example, checking whether or not the acceleration detection or the earthquake detector 8 is normally performed. For example, the communication unit 12 returns a diagnosis result from the self-diagnosis unit 16 to the maintenance device 9.

The automatic diagnosis control unit 18 has a function of executing automatic diagnosis operation via the control panel 7. The automatic diagnosis operation is an operation performed after an actual earthquake occurs in order to determine whether or not the elevator 1 may be automatically restored. By the automatic diagnosis operation, for example, it is determined whether or not the equipment of the elevator 1 is damaged.

The automatic diagnosis control unit 18 executes the automatic diagnosis operation when, for example, the maximum acceleration output by the earthquake detector 8 is included in a certain range that is equal to or less than the general reference value. The general reference value is set in advance based on, for example, an earthquake resistance standard determined by law. The general reference value is represented by a Gal value, for example.

For example, even when the maximum acceleration output by the earthquake detector 8 exceeds the general reference value, the automatic diagnosis control unit 18 has a numerical value based on the acceleration output by the earthquake detector 8 that satisfies the individual criterion. The automatic diagnosis operation is executed. The individual standard is, for example, set for each building where the elevator 1 is installed or for each elevator 1. That is, the content of the individual standard may vary depending on the building or the elevator 1.

The storage unit 19 of the maintenance device 9 stores individual reference data 23. The individual reference data 23 is, for example, data indicating an individual reference set for the elevator 1 controlled by the control panel 7 connected to the maintenance device 9 or the building where the elevator 1 is installed.

The individual standard for a certain elevator 1 or a building in which the elevator 1 is installed is set based on, for example, acceleration due to past shaking that has caused no damage to the elevator 1. The individual reference is set based on, for example, acceleration output in the past by the earthquake detector 8 provided in the elevator 1 or the building. The individual criterion is set as an upper limit value of a numerical value based on the acceleration output from the earthquake detector 8, for example.

The individual standard includes, for example, a numerical value indicating the maximum acceleration due to the past shaking that caused no damage to the elevator 1. The numerical value may be a value larger than the general reference value, for example. For example, even if the maximum acceleration due to an earthquake exceeds the general reference value, the automatic diagnosis control unit 18 executes the automatic diagnosis operation when the maximum acceleration is equal to or less than the value included in the individual reference. For example, when the maximum acceleration due to an earthquake exceeds the numerical value included in the individual reference, the automatic diagnosis control unit 18 does not execute the automatic diagnosis operation.

The individual standard includes, for example, a numerical value indicating the maximum acceleration in each shaking direction due to past shaking that did not cause any damage to the elevator 1. The numerical value may be a value larger than the general reference value, for example. For example, even if the maximum acceleration due to the earthquake exceeds the general reference value, the automatic diagnosis control unit 18 performs the automatic diagnosis operation when the maximum acceleration for each shaking direction due to the earthquake is equal to or less than the value included in the individual reference. Execute. For example, when the maximum acceleration for each shaking direction due to an earthquake exceeds the numerical value included in the individual reference, the automatic diagnosis control unit 18 does not execute the automatic diagnosis operation.

The individual standard includes, for example, a numerical value indicating the maximum shaking time due to the past shaking that caused no damage to the elevator 1. For example, even if the maximum acceleration due to an earthquake exceeds the general reference value, the automatic diagnosis control unit 18 performs an automatic diagnosis operation when the maximum shaking time due to the earthquake is equal to or less than the value included in the individual reference. For example, when the maximum shaking time due to an earthquake exceeds the numerical value included in the individual reference, the automatic diagnosis control unit 18 does not execute the automatic diagnosis operation.

The individual standard includes, for example, two or more kinds of values indicating the maximum acceleration due to the past shaking that did not cause any damage to the elevator 1, the value indicating the maximum acceleration for each shaking direction, and the value indicating the maximum shaking time. May be. For example, the automatic diagnosis control unit 18 performs automatic diagnosis operation based on a comparison result between two or more types among the maximum acceleration output from the earthquake detector 8, the maximum acceleration for each swing direction, and the maximum swing time and the individual criteria. It may be determined whether or not to execute.

The reporting unit 20 reports to the monitoring center 10. For example, the reporting unit 20 reports information related to the operation of the maintenance device 9 to the monitoring center 10. For example, the reporting unit 20 reports information indicating the state of the elevator 1 obtained from the control panel 7 to the monitoring center 10. For example, the reporting unit 20 reports information obtained from the earthquake detector 8 to the monitoring center 10. For example, the reporting unit 20 reports to the monitoring center 10 the maximum acceleration output by the earthquake detector 8 when the earthquake occurs, the maximum acceleration for each shaking direction, the maximum shaking time, and the like.

For example, when it is determined from the result of the automatic diagnosis operation that no damage has occurred in the elevator 1, the reporting unit 20 notifies the monitoring center 10 to that effect.

For example, when it is determined from the result of the automatic diagnosis operation that the elevator 1 is damaged, the reporting unit 20 requests the monitoring center 10 to dispatch a maintenance worker.

For example, when the numerical value based on the acceleration output by the earthquake detector 8 does not satisfy the individual standard, the reporting unit 20 requests the monitoring center 10 to dispatch a maintenance worker.

The maintenance worker performs the inspection work of the elevator 1 in response to the request for dispatch. The maintenance worker reports completion to the monitoring center 10 after the work is completed. The completion report may be performed, for example, via the control panel 7 or the maintenance device 9. The completion report may be made directly to the monitoring center 10, for example. The content of the completion report includes, for example, information indicating whether or not physical damage has actually occurred in the elevator 1.

The storage unit 21 of the monitoring center 10 stores accumulated data 24 and individual reference data 25.

The accumulated data 24 is, for example, data indicating numerical values based on accelerations output in the past by the earthquake detector 8 corresponding to the elevator 1 to be monitored by the monitoring center 10. The accumulated data 24 may include output data of a plurality of earthquake detectors 8 corresponding to different elevators 1 or different buildings. The accumulated data 24 includes, for example, maximum acceleration, maximum acceleration for each swing direction, maximum swing time, and the like.

The individual reference data 25 is, for example, data indicating an individual reference set for the elevator 1 to be monitored by the monitoring center 10 or the building where the elevator 1 is installed. The individual reference data 25 may include a plurality of individual standards corresponding to different elevators 1 or different buildings. The individual reference data 25 is set based on the accumulated data 24, for example.

The update unit 22 changes the individual reference for the building or the elevator 1 corresponding to the earthquake detector 8 in the individual reference data 25 based on the latest output data of the earthquake detector 8, for example. For example, the update unit 22 changes the individual reference data 23 corresponding to the changed individual reference in the individual reference data 25. That is, the update unit 22 updates the individual reference stored in the maintenance device 9. Note that the individual reference data 23 stored in the storage unit 19 is not changed by an operation on the control panel 7 and the maintenance device 9, for example.

For example, when the maximum acceleration due to an earthquake exceeds the general reference value, the updating unit 22 does not satisfy the individual standard for the numerical value based on the acceleration output by the earthquake detector 8 and causes damage to the elevator 1. If there is a completion report indicating that it was not, the numerical value is set as a new individual standard. In other words, for example, the update unit 22 has, for example, the case in which no physical loss has occurred in the elevator 1 even though the current swing is greater than the previous swing in which the physical loss has not occurred in the elevator 1, The individual standard is revised upward.

For example, when the maximum acceleration due to an earthquake exceeds the general reference value, the updating unit 22 satisfies the individual criterion for the numerical value based on the acceleration output by the earthquake detector 8 and the property damage has occurred in the elevator 1. If there is a completion report indicating this, the numerical value is set as a new individual standard. In other words, for example, the updating unit 22 may be configured to perform an individual case when a physical loss has occurred in the elevator 1 even though the current swing is smaller than a previous swing that has not caused the physical loss in the elevator 1. The standard is revised downward.

FIG. 3 is a diagram for explaining the restoration of the elevator after the earthquake.

FIG. 3 shows an example of countermeasures according to the maximum acceleration value output by the earthquake detector 8. As shown in FIG. 3, for example, Gal values corresponding to “extra low”, “low”, “high”, and “diagnosis” are set as the reference of the maximum acceleration output by the earthquake detector 8. “High” corresponds to, for example, a general reference value set for the earthquake-resistant class A elevator 1. “Diagnosis” corresponds to, for example, a general reference value set for the elevator 1 of the earthquake resistance class S.

For example, when the maximum acceleration output by the earthquake detector 8 is equal to or less than “extra low”, the normal traveling of the elevator 1 is continued.

For example, when the maximum acceleration output by the earthquake detector 8 is greater than “extra low” and less than or equal to “low”, the elevator 1 is automatically reset after a certain period of time after stopping temporarily. The elevator 1 resumes operation after the automatic reset.

For example, when the maximum acceleration output by the earthquake detector 8 is greater than “low” and less than “high”, automatic diagnosis operation of the earthquake-resistant class A and earthquake-resistant class S elevators 1 is performed.

For example, when the maximum acceleration output by the earthquake detector 8 is greater than “high” and less than or equal to “diagnosis”, automatic diagnosis operation of the earthquake-resistant class S elevator 1 is performed.

For example, conventionally, when the maximum acceleration output by the earthquake detector 8 is greater than “high”, the earthquake-resistant class A elevator 1 has to be restored by a maintenance worker. For example, conventionally, when the maximum acceleration output by the earthquake detector 8 is larger than “diagnosis”, the earthquake-resistant class S elevator 1 has to be restored by a maintenance worker. On the other hand, according to the first embodiment, even if the maximum acceleration output by the earthquake detector 8 is greater than “high” or “diagnosis”, the automatic diagnosis operation of the elevator 1 is performed based on the individual criteria. Done.

FIG. 4 is a flowchart showing an operation example of the elevator automatic recovery system according to the first embodiment.

When an earthquake occurs, the automatic diagnosis control unit 18 determines whether or not the maximum acceleration output by the earthquake detector 8 is equal to or less than “extra low” (step S101). If it is determined in step S101 that the maximum acceleration is equal to or less than “extra low”, the service of the elevator 1 is continued.

If it is determined in step S101 that the maximum acceleration is greater than “extra low”, the elevator 1 stops (step S102). The automatic diagnosis control unit 18 determines whether or not the maximum acceleration output by the earthquake detector 8 is “low” or less (step S103). If it is determined in step S103 that the maximum acceleration is “low” or less, the elevator 1 is automatically reset, for example, after one minute (step S104). After step S104, the service of the elevator 1 is continued.

If it is determined in step S103 that the maximum acceleration is greater than “low”, the automatic diagnosis control unit 18 determines whether or not the maximum acceleration output by the earthquake detector 8 is “high” or less ( Step S105). If it is determined in step S105 that the maximum acceleration is equal to or less than “high”, the process of step S108 is performed.

When it is determined in step S105 that the maximum acceleration is greater than “high”, the automatic diagnosis control unit 18 determines whether or not the earthquake resistance class of the elevator 1 is the earthquake resistance class S (step S106). If it is determined in step S106 that the earthquake resistance class S, the automatic diagnosis control unit 18 determines whether or not the maximum acceleration output by the earthquake detector 8 is equal to or less than “diagnosis” (step S107). If it is determined in step S107 that the maximum acceleration is equal to or less than “diagnosis”, the process of step S108 is performed.

In step S108, the reporting unit 20 reports to the monitoring center 10. The content notified in step S108 indicates that, for example, automatic diagnosis operation is executed. Subsequent to step S108, the automatic diagnosis control unit 18 executes an automatic diagnosis operation of the elevator 1 (step S109). The automatic diagnosis control unit 18 determines whether there is a physical loss in the elevator 1 based on the result of the automatic diagnosis operation (step S110). When it is determined in step S110 that the elevator 1 has no physical damage, the reporting unit 20 reports to the monitoring center 10 (step S111). The content notified in step S111 indicates, for example, that the elevator 1 has no physical damage. In this case, the service of the elevator 1 is continued.

When it is determined in step S110 that the elevator 1 is damaged, the reporting unit 20 reports to the monitoring center 10 (step S112). The content notified in step S112 is, for example, a maintenance worker dispatch request. The maintenance worker inspects and repairs the elevator 1 in response to the dispatch request (step S113). The maintenance worker reports completion to the monitoring center 10 after completion of the work (step S114).

If it is determined in step S106 that it is not the earthquake resistant class S, the process of step S115 is performed. If it is determined in step S107 that the maximum acceleration is greater than “diagnosis”, the process of step S115 is performed.

In step S115, the automatic diagnosis control unit 18 determines whether or not the automatic diagnosis operation using the individual criteria can be executed. The determination in step S115 is based on, for example, whether or not there is a maintenance contract for the elevator 1 regarding automatic diagnosis operation using an individual criterion. If it is determined in step S115 that the automatic diagnosis operation using the individual reference is not possible, the process of step S112 is performed.

When it is determined in step S115 that the automatic diagnosis operation using the individual reference can be performed, the automatic diagnosis control unit 18 acquires output data based on the acceleration due to the current earthquake from the earthquake detector 8 (step S116). ). The reporting unit 20 reports the output data to the monitoring center 10 (step S117). The automatic diagnosis control unit 18 determines whether or not the acquired output data satisfies the individual criteria (step S118).

If it is determined in step S118 that the output data satisfies the individual criteria, the process of step S108 is performed. If it is determined in step S118 that the output data does not satisfy the individual criteria, the process of step S112 is performed.

In the first embodiment, the communication unit 12 of the earthquake detector 8 has a function of performing bidirectional communication with the control panel 7 of the elevator 1. The communication unit 12 transmits, for example, a numerical value indicating the maximum acceleration, a numerical value indicating the maximum acceleration for each shaking direction, and a numerical value indicating the maximum shaking time to the control panel 7. That is, the output data of the earthquake detector 8 is not a simple contact signal corresponding to the magnitude of the shaking, but is a detailed numerical value representing the characteristics of the shaking. Therefore, according to the first embodiment, it is possible to extend services such as elevator control operation and automatic diagnosis operation when an earthquake occurs, using the output data of the earthquake detector. Further, according to the first embodiment, it is possible to easily check the connection state between the earthquake detector and the control panel.

In Embodiment 1, the earthquake detector 8 may have, for example, a vibration generating unit. The vibration generating unit has a function of generating vibration by a servo motor or the like, for example. For example, the self-diagnosis unit 16 operates the vibration generation unit based on the function diagnosis command transmitted from the sensor control unit 17. For example, the self-diagnosis unit 16 determines whether or not various numerical values detected by the acceleration detection unit 13, the swing direction detection unit 14, and the swing time detection unit 15 after the start of the operation of the vibration generation unit are normal. The communication unit 12 returns, for example, various numerical values and the determination result by the self-diagnosis unit 16 to the maintenance device 9. Thereby, it can be easily confirmed that the seismic detector operates normally when an actual earthquake occurs. Note that the vibration generation unit may be provided as a separate device from the earthquake detector 8 as long as vibration can be transmitted to the earthquake detector 8.

In the first embodiment, the automatic diagnosis control unit 18 has a function of executing an automatic diagnosis operation of the elevator 1 after the occurrence of an earthquake, and the maximum acceleration output by the earthquake detector 8 is equal to or less than a preset general reference value. Automatic diagnosis operation is executed when it falls within a certain range. The storage unit 19 stores individual standards set for each building or for each elevator 1. The automatic diagnosis control unit 18 stores a numerical value based on the acceleration output by the earthquake detector 8 in the storage unit 19 even when the maximum acceleration output by the earthquake detector 8 exceeds the general reference value. If the individual criteria are met, automatic diagnostic operation is executed. For this reason, according to Embodiment 1, an automatic diagnostic driving | operation can be performed according to the earthquake resistance capability of each building or each elevator. As a result, the percentage of elevators that automatically recover after an earthquake can be increased. In addition, it is possible to reduce the load on maintenance workers after the earthquake.

In the first embodiment, the individual standard includes, for example, the maximum acceleration due to the past shaking that caused no physical damage to the elevator 1. For example, the automatic diagnosis control unit 18 determines whether or not to execute the automatic diagnosis operation based on the comparison result between the maximum acceleration output by the earthquake detector 8 and the individual reference. For this reason, an automatic diagnostic driving | operation can be performed according to the earthquake resistance capability of each building or each elevator.

In the first embodiment, the individual standard includes, for example, the maximum acceleration for each shaking direction due to the past shaking that did not cause any damage to the elevator 1. For example, the automatic diagnosis control unit 18 determines whether or not to execute the automatic diagnosis operation based on the comparison result between the maximum acceleration for each shaking direction output by the earthquake detector 8 and the individual reference. In this case, it is possible to determine whether or not to execute the automatic diagnosis operation in consideration of the fact that the seismic capacity of the building or the elevator varies depending on the shaking direction. For this reason, an automatic diagnostic driving | operation can be performed according to the detailed earthquake-proof capability of each building or each elevator.

In the first embodiment, the individual standard includes, for example, the maximum shaking time due to the past shaking that did not cause any damage to the elevator 1. For example, the automatic diagnosis control unit 18 determines whether or not to execute the automatic diagnosis operation based on the comparison result between the maximum shaking time output by the earthquake detector 8 and the individual reference. In this case, it is possible to determine whether or not to execute the automatic diagnosis operation in consideration of the fact that the seismic capacity of the building or the elevator varies depending on the shaking time. For this reason, an automatic diagnostic driving | operation can be performed according to the detailed earthquake-proof capability of each building or each elevator.

In the first embodiment, the automatic diagnosis control unit 18 is based on, for example, a comparison result between at least two types among the maximum acceleration output by the earthquake detector 8, the maximum acceleration for each swing direction, and the maximum swing time and the individual reference. To determine whether or not to execute the automatic diagnosis operation. For this reason, automatic diagnosis operation can be performed according to the more detailed seismic capacity of each building or each elevator.

In the first embodiment, the individual standard is set based on, for example, the acceleration due to the past shaking that caused no physical damage to the elevator 1. For this reason, an automatic diagnostic driving | operation can be performed according to the actual earthquake-proof capability of each building or each elevator.

In Embodiment 1, the update unit 22 updates the individual standard stored in the storage unit 19, for example. The automatic diagnosis control unit 18 and the storage unit 19 are provided, for example, in the maintenance device 9 installed in the same building as the elevator 1. The update unit 22 is provided in the monitoring center 10 that can communicate with the maintenance device 9, for example. For this reason, it can prevent that a maintenance worker changes an individual standard accidentally at the time of inspection of an elevator.

In the first embodiment, for example, when the maximum acceleration output by the earthquake detector 8 exceeds the general reference value, the updating unit 22 satisfies the individual criterion with the numerical value based on the acceleration output by the earthquake detector 8. In addition, when it is confirmed by a maintenance worker that no physical damage has occurred in the elevator 1, the numerical value is set as an individual standard. That is, the update unit 22 upwardly corrects the individual standard for the building or the elevator 1 having high earthquake resistance. For this reason, an automatic diagnostic driving | operation can be performed according to the actual earthquake-proof capability of each building or each elevator.

In the first embodiment, for example, when the maximum acceleration output by the earthquake detector 8 exceeds the general reference value, the update unit 22 satisfies the individual criterion with the numerical value based on the acceleration output by the earthquake detector 8. And when it is confirmed by the maintenance worker that the physical loss has occurred in the elevator 1, the numerical value is set as an individual standard. That is, the update unit 22 corrects the individual standard for the building or the elevator 1 having a low earthquake resistance. For this reason, an automatic diagnostic driving | operation can be performed according to the actual earthquake-proof capability of each building or each elevator.

In the first embodiment, an individual standard for an elevator 1 or a building in which the elevator 1 is installed is output in the past by, for example, the earthquake detector 8 provided at a location different from the elevator 1 or the building. It may be set based on the acceleration. The individual reference for a certain elevator 1 may be set based on, for example, an acceleration output in the past by an earthquake detector 8 provided in another elevator 1 having the same or similar model and hoistway dimensions. Individual standards for a building are set based on, for example, accelerations output in the past by seismic detectors 8 provided in other buildings with the same or similar floor number, building age, planar shape, structural material, and ground. May be. In this case, for example, an appropriate individual standard can be set for a newly installed elevator or a newly completed building.
