Technical Field
An embodiment of the present invention relates to a maintenance work support system for an elevator.
Background
An elevator is an extremely important device for ensuring safety, and maintenance work is periodically performed to ensure safety. The maintenance work of the elevator includes the following operations: in a state where no abnormality has actually occurred, the operation of the elevator is intentionally checked so that the abnormality is detected. In general, an elevator is provided with a function of reporting an abnormality when an abnormality is detected, but when the elevator is intentionally brought into a state where an abnormality is detected during maintenance work, it is preferable not to report an abnormality. Therefore, a switch for switching between the validity and the invalidity of the abnormality report is provided, and when the maintenance work of the elevator is performed, the operator can invalidate the abnormality report by operating the switch.
However, since this switch is manually operated by an operator, the operator may forget to return the switch after the maintenance operation is completed. If the abnormality report is left unused due to forgetting to return the switch, there is a possibility that the abnormality report will not be issued even if an abnormality occurs during normal operation of the elevator, which may cause a problem.

Detailed Description
Hereinafter, a maintenance work support system for an elevator according to an embodiment will be described in detail with reference to the drawings. In the following description, the same reference numerals are given to components having the same functions, and overlapping description is appropriately omitted.
< embodiment 1 >
First, the configuration of the maintenance work support system for an elevator according to embodiment 1 will be described with reference to fig. 1 and 2. Fig. 1 is a block diagram showing a configuration example of an elevator maintenance work support system according to embodiment 1, and fig. 2 is a perspective view of a housing provided with a nullifying switch.
As shown in fig. 1, the maintenance work support system for an elevator according to the present embodiment includes an elevator control device 10 provided as an elevator apparatus, an invalidation switch 20, a cover closing detector 30, and an operator terminal 50 operated by an operator who performs maintenance work on the elevator.
The elevator control device 10 collects various information related to the operation of the elevator and controls the operation of the elevator. The elevator control device 10 includes an abnormality notification unit 11, a notification unit 12, and a completion determination unit 13 as functional components related to the present embodiment. These functional components can be realized by executing a predetermined program, that is, by software, by a processor included in a microcomputer in the elevator control device 10, for example. All or a part of these functional components may be configured by dedicated hardware such as asic (application specific Integrated circuit) or fpga (field Programmable Gate array). These functional components may be implemented by a device different from the elevator control device 10 (external to the elevator control device 10).
The abnormality notification unit 11 is configured to, when an abnormality of the elevator is detected, notify a predetermined external notification destination of the occurrence of the abnormality (abnormality notification). The external report destination is, for example, a terminal of a manager's room for managing the elevator facility, a monitoring panel of a service information center when a remote maintenance contract for the elevator is entered, or the like.
The invalidation switch 20 is a switch for switching between validation and invalidation of the abnormality report by the abnormality report unit 11 in response to an operation by an operator who performs the maintenance operation. The invalidation switch 20 is installed in a hall maintenance device installed in a hall of a predetermined floor, for example. As shown in fig. 2, the lobby maintenance device includes a housing 100, and the housing 100 has a cover 101 that can be opened and closed by a maintenance operator by a key operation or the like. The invalidation switch 20 is disposed inside the housing 100 together with other switches operated at the time of maintenance and inspection. Examples of the other switches include a switch for switching the operation mode of the elevator to the inspection mode, a switch for controlling the elevator by the operator terminal 50 allowing an operator to operate, and the like.
The invalidation switch 20 is connected to the elevator control device 10. When the invalidation switch 20 is operated to the on side (CUT side) by an operator who performs the maintenance operation, the abnormality report of the abnormality report unit 11 is invalidated, and when the invalidation switch is operated to the off side (NOR side), the abnormality report is validated. In a normal case, before starting the maintenance operation, the worker who performs the maintenance operation operates the invalidation switch 20 to the on side to invalidate the abnormality report of the abnormality notification unit 11, and returns the invalidation switch 20 to the off side to validate the abnormality report when the maintenance operation is finished, but sometimes forgets to return the invalidation switch 20.
The cover closing detector 30 detects a closed state of the cover 101 of the housing 100 that houses the invalidation switch 20. The cover closing detector 30 may be configured to detect the closed state of the cover 101, and any method such as mechanical, electrical, or optical may be used as a detection method. The cover closing detector 30 transmits a detection signal that is valid when the cover 101 is in the closed state to the elevator control device 10. Thus, the elevator control device 10 can recognize whether the cover 101 of the housing 100 that houses the invalidation switch 20 is in the open state or the closed state.
In the present embodiment, it is assumed that the invalidation switch 20 is provided in the hall maintenance device, but the invalidation switch 20 may be disposed inside the housing of the elevator control device 10. In this case, the cover closing detector 30 detects the closed state of the cover of the housing of the elevator control apparatus 10.
The notification unit 12 performs a predetermined notification operation when the lid closure detector 30 detects that the lid 101 of the housing 100 accommodating the invalidation switch 20 is closed in a state where the abnormality report of the abnormality report unit 11 is invalidated, that is, in a state where the invalidation switch 20 is operated to the on side. The notification operation here is an operation for making the operator who has performed the operation of closing the cover 101 notice that the invalidation switch 20 has not been returned to the closing side, and is, for example, a buzzer sound. Note that the notification operation may be an operation that draws the attention of the operator, and various operations such as turning on and off of a warning lamp, outputting of a sound broadcast, and displaying of a message may be applied in addition to the sounding of a buzzer.
The operator terminal 50 is a terminal that is carried by an operator and operated when performing maintenance work, and is connected to the elevator control device 10 by wire or wireless, and communicates with the elevator control device 10. In the present embodiment, when the operator finishes the maintenance operation, the operator operates the operator terminal 50 and sends a notification of the completion of the maintenance operation to the elevator control device 10. The operator terminal 50 may be a dedicated console device for maintenance work, or may be a smartphone, a tablet terminal, a notebook personal computer, or the like, to which application software for maintenance work is installed. In the present embodiment, it is assumed that the operator terminal 50 and the elevator control device 10 communicate directly with each other, but when a remote maintenance contract for an elevator is made, the operator terminal 50 may be configured to communicate indirectly with the elevator control device 10 via a server or the like of a service information center.
The completion determination unit 13 determines that the maintenance operation is completed when a notification of completion of the maintenance operation (maintenance operation completion notification) is received from the operator terminal 50 in a state where the abnormality report of the abnormality report unit 11 is validated and the cover closing detector 30 detects that the cover 101 of the enclosure 100 housing the invalidation switch 20 is in the closed state. That is, the completion determination unit 13 determines that the maintenance operation is completed after confirming that the invalidation switch 20 is correctly returned to the closed side and the cover 101 is closed when the maintenance operation completion notification is received from the operator terminal 50. In other words, even if there is a notification from the operator terminal 50 that the maintenance operation is completed, the invalidation switch 20 is not determined to be completed when it is kept in the state of being operated to the open side or when the cover 101 is kept in the open state. The completion of the maintenance job is recorded as a log, for example. Further, when completion of the maintenance work is confirmed, a work report of the maintenance work may be made.
Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to fig. 3 and 4. Fig. 3 and 4 are flowcharts showing an example of operation of the elevator maintenance work support system according to the present embodiment, fig. 3 shows an example of a processing procedure relating to switching between validity and invalidity of an abnormality report, and fig. 4 shows an example of a processing procedure of the completion determination unit 13.
First, a process related to switching between validity and invalidity of an exception report will be described with reference to fig. 3. When the invalidation switch 20 is operated to the on side by the worker who performs the maintenance operation (yes in step S101), the abnormality report of the abnormality report section 11 is switched from valid to invalid according to the operation (step S102). In addition, if the invalidation switch 20 is not operated to the on side (step S101: NO), the process is directly ended.
Thereafter, it is determined whether or not the invalidation switch 20 is operated to the off side (step S103), and when the invalidation switch 20 is operated to the off side (step S103: YES), the abnormality report of the abnormality report section 11 is switched from invalid to valid (step S104). On the other hand, if the invalidation switch 20 is not operated to the closing side (step S103: no), it is determined whether the cover closing detector 30 detects that the cover 101 of the housing 100 housing the invalidation switch 20 is closed (step S105). Then, if closing of the cover 101 is not detected (NO in step S105), the process returns to step S103, and the determination in step S103 and step S104 is repeated.
On the other hand, when closing of the cover 101 is detected (yes in step S105) while the invalidation switch 20 is not operated to the closed side, that is, while the abnormality report of the abnormality report section 11 is kept invalid, the notification operation of the notification section 12 is performed (step S106), and the series of processing ends. By this notification operation, the worker performing the maintenance operation can notice that he or she has forgotten to return the invalidation switch 20 at the timing of closing the cover 101 of the housing 100.
Next, the process of the completion determination unit 13 will be described with reference to fig. 4. When receiving the maintenance work completion notification from the operator terminal 50 (yes in step S201), the completion determination unit 13 checks whether or not the abnormality report by the abnormality report unit 11 is valid (step S202). Then, if the abnormality report is set to be valid (step S202: YES), it is confirmed whether or not the closed state of the lid 101 of the casing 100 is detected by the lid-closing detector 30 (step S203). Here, when it is confirmed that the abnormality report is valid and the closed state of the cover 101 is detected (yes in step S203), the completion determination unit 13 determines that the maintenance work is completed (step S204).
On the other hand, when the maintenance work completion notification is not received from the operator terminal 50 (no in step S201), when the abnormality report by the abnormality report section 11 is invalidated (no in step S202), or when the closed state of the cover 101 of the housing 100, that is, the state in which the cover 101 is kept open is not detected (no in step S203), the process is terminated without determining that the maintenance work is completed.
As described above, the maintenance work support system for an elevator according to the present embodiment performs a notification operation such as a buzzer sound when it is detected that the cover 101 of the housing 100 accommodating the invalidation switch 20 is closed in a state where the invalidation switch 20 is operated to the on side and the abnormality report of the abnormality notification unit 11 is kept invalidated. Therefore, when the worker who performs the maintenance operation finishes the maintenance operation and forgets to return the invalidation switch 20 to the off side, and directly closes the cover 101 of the housing 100, the worker can be notified of the forgetting to return the invalidation switch 20 by the notification operation, and the abnormality report of the abnormality report part 11 can be effectively prevented from being left without being invalidated after the maintenance operation is finished.
Further, according to the maintenance work support system for an elevator of the present embodiment, it is determined that the maintenance work is completed when there is a maintenance work end notification from the worker terminal 50 on the condition that the invalidation switch 20 is returned to the closed side, the abnormality report of the abnormality notifying unit 11 is validated, and the cover 101 of the housing 100 that houses the invalidation switch 20 is closed, and therefore, it is possible to further effectively prevent the abnormality report of the abnormality notifying unit 11 from remaining in a state of being invalidated after the maintenance work is completed.
< embodiment 2 >
Next, embodiment 2 will be explained. An operator performing the maintenance work may operate the invalidation switch 20 to the on side to invalidate the abnormality report of the abnormality report section 11, and then close the cover 101 of the housing 100 to start the maintenance work. At this time, although the notification operation of the notification unit 12 is performed, it is assumed that the worker intends to return the invalidation switch 20 to the off side when the maintenance operation is completed and ignore the notification operation. In this case, even if the operator forgets to return the invalidation switch 20 when the maintenance operation is completed, the operator cannot be notified of the forgetting to return the invalidation switch 20.
Therefore, in the present embodiment, the elapsed time from the detection of the closing of the cover 101 of the housing 100 in the state where the abnormality report of the abnormality report section 11 is invalidated is measured, and when the abnormality report is not validated before the elapsed time reaches the predetermined time, the notification operation is further performed to the external notification destination (external device). For example, the predetermined time is set to a time obtained by adding a predetermined margin to the average time required from the start to the end of the maintenance work. The external notification destination is, for example, an operator terminal 50 carried by an operator who performs maintenance work, a server of a service information center, or the like. Since other functions and operations are the same as those of embodiment 1 described above, only the characteristic portions of the present embodiment will be described below.
Fig. 5 is a block diagram showing an example of the configuration of the maintenance work support system for an elevator according to embodiment 2. In the present embodiment, as shown in fig. 5, a measurement unit 14 is added as a functional component implemented in the elevator control device 10.
The measurement unit 14 measures an elapsed time from the detection of the closing of the cover 101 of the housing 100 by the cover closing detector 30 in a state where the invalidation switch 20 is operated to the on side and the abnormality report of the abnormality notification unit 11 is invalidated.
Note that, the notification unit 12 of the present embodiment performs the same notification operation as in embodiment 1 described above, and further performs a notification operation to notify an external destination when the invalidation switch 20 is not operated to the closed side and the abnormality notification of the abnormality notification unit 11 is validated before the elapsed time measured by the measurement unit 14 reaches the predetermined time. The notification operation here is, for example, an operation of displaying a message indicating that the invalidation switch 20 has been forgotten to be returned to the external device, or outputting a sound broadcast indicating that the invalidation switch 20 has been forgotten to be returned from the external device.
Next, the operation of the maintenance work support system for an elevator according to the present embodiment will be described with reference to fig. 6. Fig. 6 is a flowchart showing an example of the operation of the maintenance work support system for an elevator according to the present embodiment, and shows an example of a processing procedure relating to the switching between the validity and invalidity of the abnormality report. The processing from step S301 to step S305 in fig. 6 is the same as that in embodiment 1 described above (the processing from step S101 to step S105 in fig. 3), and therefore, the description thereof is omitted.
In the present embodiment, when closing of the cover 101 is detected (yes in step S305) while the invalidation switch 20 is not operated to the closing side, that is, while the abnormality report holding of the abnormality report section 11 is disabled, the measurement section 14 starts measuring the elapsed time (step S306), and the notification section 12 performs the notification operation (step S307). Thereafter, whether or not the invalidation switch 20 is operated to the off side is monitored (step S308), and when the invalidation switch 20 is operated to the off side (YES in step S308), the process proceeds to step S304, and the abnormality report by the abnormality report section 11 is switched from invalid to valid.
On the other hand, if the invalidation switch 20 is not operated to the closed side and the abnormality report of the abnormality reporting unit 11 is kept in the invalid state (no in step S308), it is determined whether the elapsed time measured by the measurement unit 14 has reached the predetermined time (step S309). Then, if the elapsed time measured by the measurement unit 14 has not reached the predetermined time (NO at step S309), the process returns to step S308 and the determination at step S308 and step S309 are repeated. On the other hand, when the invalidation switch 20 is not operated to the closing side and the elapsed time reaches the predetermined time (step S308), the notification unit 12 performs a notification operation to the external notification destination (step S310), and the series of processes is ended.
As described above, the maintenance work support system for an elevator according to the present embodiment measures an elapsed time from the detection of the closing of the cover 101 of the housing 100 in a state where the abnormality report of the abnormality report section 11 is invalidated, and further performs the notification operation to the external notification destination when the invalidation switch 20 is not operated to the closed side and the abnormality report of the abnormality report section 11 is not validated before the elapsed time reaches the predetermined time. Therefore, even if the worker performing the maintenance operation starts the maintenance operation with the cover 101 of the housing 100 housing the invalidation switch 20 closed and forgets to return the invalidation switch 20 after the maintenance operation is completed, the worker can notice that the worker forgets to return the invalidation switch 20, and can further effectively prevent the abnormality report of the abnormality notification unit 11 from being left without being invalidated after the maintenance operation is completed.
< embodiment 3 >
Next, embodiment 3 will be explained. In the present embodiment, when forgetting to return the invalidation switch 20, the abnormality report of the abnormality report section 11 can be validated by a command input from the outside of the elevator. However, in order to prevent the abnormal report from being validated carelessly during the maintenance work, the input of the command from the outside is permitted on the condition that the abnormal report is invalidated and the closed state of the cover 101 of the casing 100 is detected by the cover closing detector 30. Since other functions and operations are the same as those of embodiment 1 described above, only the characteristic portions of the present embodiment will be described below.
Fig. 7 is a block diagram showing an example of the configuration of the maintenance work support system for an elevator according to embodiment 3. In the present embodiment, as shown in fig. 7, a remote validation unit 15 is added as a functional component implemented in the elevator control device 10.
The remote validation unit 15 validates the abnormality report of the abnormality report unit 11 that has been invalidated in response to the invalidation command input from the external command source in a state where the invalidation switch 20 is operated to the on side, the abnormality report of the abnormality report unit 11 is invalidated, and the cover closing detector 30 detects that the cover 101 of the housing 100 that houses the invalidation switch 20 is closed. The command transmission source is, for example, an operator terminal 50 carried by an operator who performs maintenance work, a server of a service information center, or the like.
Next, the operation of the maintenance work support system for an elevator according to the present embodiment will be described with reference to fig. 8. Fig. 8 is a flowchart showing an example of the operation of the maintenance work support system for an elevator according to the present embodiment, and shows an example of a processing procedure relating to the switching between the validity and invalidity of the abnormality report. The processing from step S401 to step S405 in fig. 8 is the same as that in embodiment 1 (the processing from step S101 to step S106 in fig. 3), and therefore, the description thereof is omitted.
In the present embodiment, in a state where the abnormality report holding by the abnormality report section 11 is disabled, after the closing of the cover 101 is detected and the notification operation is performed by the notification section 12 in step S405, the remote validation section 15 monitors whether or not a validation command is input from an external command transmission source (step S406). When the validation command is input from the external command transmission source (yes in step S406), the remote validation unit 15 switches the abnormality report of the abnormality report unit 11 from invalid to valid (step S407).
As described above, the maintenance work support system for an elevator according to the present embodiment is configured to validate an abnormality report of the abnormality notification unit 11 in accordance with a validation command when the validation command is input from an external command source in a state where the abnormality report of the abnormality notification unit 11 is invalidated and it is detected that the cover 101 of the housing 100 accommodating the invalidation switch 20 is in a closed state. Therefore, when forgetting to return the invalidation switch 20 after the maintenance work is completed, the remote operation can validate the abnormality report of the abnormality reporting unit 11, and it is possible to further effectively prevent the abnormality report of the abnormality reporting unit 11 from being left without being invalidated after the maintenance work is completed.
< embodiment 4 >
Next, embodiment 4 will be explained. In the present embodiment, as in the above-described embodiment 3, the abnormality report of the abnormality report section 11 can be validated by a validation command input from an external command source, but as a condition for permitting the input of a command from the outside, a condition is added in which the elapsed time from the detection of the closing of the cover 101 of the housing 100 in a state in which the abnormality report of the abnormality report section 11 is invalidated exceeds a predetermined time.
That is, in the present embodiment, as in the above-described embodiment 2, the elapsed time from the detection of the closing of the cover 101 of the housing 100 in a state where the abnormality report by the abnormality report unit 11 is invalidated is measured. When the abnormality report of the abnormality report unit 11 is invalidated and the cover closing detector 30 detects that the cover 101 of the casing 100 is in the closed state, and when an activation command is input from an external command source after a lapse of a predetermined time, the abnormality report of the abnormality report unit 11 is activated based on the activation command. Since other functions and operations are the same as those of embodiment 1 described above, only the characteristic portions of the present embodiment will be described below.
Fig. 9 is a block diagram showing an example of the configuration of the maintenance work support system for an elevator according to embodiment 4. In the present embodiment, as shown in fig. 9, a measurement unit 14 and a remote validation unit 15 are added as functional components implemented in the elevator control device 10.
The measurement unit 14 measures an elapsed time from the detection of the closing of the cover 101 of the housing 100 in a state where the abnormality report of the abnormality report unit 11 is disabled, similarly to the measurement unit 14 of the above-described embodiment 2.
The remote validation unit 15 is similar to the remote validation unit 15 according to embodiment 3 described above, and validates the abnormality report of the abnormality reporting unit 11 based on the invalidation command when the invalidation command is input from the external command transmission source in a state where the abnormality report of the abnormality reporting unit 11 is invalidated and the closing of the cover 101 of the housing 100 is detected. However, the remote validation unit 15 according to the present embodiment does not receive the input of the invalidation command until the elapsed time measured by the measurement unit 14 reaches the predetermined time, and receives the input of the invalidation command to validate the abnormality report of the abnormality notification unit 11 after the elapsed time measured by the measurement unit 14 exceeds the predetermined time. The predetermined time is set to a time obtained by adding a predetermined margin to the average time required from the start to the end of the maintenance operation, for example, as in embodiment 2 described above.
Next, the operation of the maintenance work support system for an elevator according to the present embodiment will be described with reference to fig. 10. Fig. 10 is a flowchart showing an example of the operation of the maintenance work support system for an elevator according to the present embodiment, and shows an example of a processing procedure relating to the switching between the validity and invalidity of the abnormality report. The processing from step S501 to step S504 in fig. 10 is the same as that in embodiment 3 described above (the processing from step S401 to step S404 in fig. 8), and therefore, the description thereof is omitted.
In the present embodiment, when closing of the cover 101 is detected (yes in step S504) while the invalidation switch 20 is not operated to the closing side, that is, while the abnormality report holding of the abnormality notifying unit 11 is disabled, the measurement unit 14 starts measuring the elapsed time (step S505) and the notifying unit 12 performs the notifying operation (step S506). After that, the remote validation unit 15 monitors whether or not a validation command is input from an external command transmission source (step S507). When an activation command is input from an external command source (step S507: yes), it is determined whether or not the elapsed time measured by the measurement unit 14 exceeds a predetermined time (step S508).
Here, if the elapsed time measured by the measurement unit 14 does not exceed the predetermined time (no in step S508), the process returns to step S507 without receiving an input of a validation command from an external transmission source. On the other hand, if the elapsed time measured by the measurement unit 14 exceeds the predetermined time (step S508: YES), the remote validation unit 15 switches the abnormality report of the abnormality report unit 11 from invalid to valid in accordance with the validation command (step S509).
As described above, the maintenance work support system for an elevator according to the present embodiment is configured to validate an abnormality report of the abnormality notification unit 11 based on a validation command when the abnormality report of the abnormality notification unit 11 is invalidated and it is detected that the cover 101 of the housing 100 accommodating the invalidation switch 20 is in the closed state and the validation command is input from an external command source after an elapsed time from the state of the abnormality report exceeds a predetermined time. Therefore, as in the case of embodiment 3 described above, when forgetting to return the invalidation switch 20 after the maintenance operation is completed, the abnormality report of the abnormality report unit 11 can be validated by remote operation, and it is possible to further effectively prevent the abnormality report of the abnormality report unit 11 from being left without being invalidated after the maintenance operation is completed.
In particular, in the present embodiment, as the condition for allowing the input of the validation command from the external command source, the condition that the elapsed time from the detection of the closing of the cover 101 of the housing 100 in the state where the abnormality report of the abnormality report section 11 is invalidated exceeds the predetermined time is added, and therefore, it is possible to effectively prevent the trouble that the abnormality report of the abnormality report section 11 is validated by the validation command before the maintenance work is finished.
< embodiment 5 >
Next, embodiment 5 will be explained. In the present embodiment, when a predetermined time has elapsed from the detection of the closing of the cover 101 of the housing 100 in a state where the abnormality report by the abnormality report unit 11 is disabled, the abnormality report by the abnormality report unit 11 is automatically validated. That is, in the present embodiment, as in the above-described embodiment 2, the elapsed time from the detection of the closing of the cover 101 of the housing 100 in a state where the abnormality report by the abnormality report unit 11 is invalidated is measured. When the elapsed time reaches a predetermined time, the abnormality report of the abnormality report unit 11 is validated. Since other functions and operations are the same as those of embodiment 1 described above, only the characteristic portions of the present embodiment will be described below.
Fig. 11 is a block diagram showing an example of the configuration of the maintenance work support system for an elevator according to embodiment 5. In the present embodiment, as shown in fig. 11, a measurement unit 14 and an automatic validation unit 16 are added as functional components implemented in the elevator control device 10.
The measurement unit 14 measures an elapsed time from the detection of the closing of the cover 101 of the housing 100 in a state where the abnormality report of the abnormality report unit 11 is disabled, similarly to the measurement unit 14 of the above-described embodiment 2.
The automatic validation unit 16 validates the abnormal report of the abnormal reporting unit 11 that is invalidated when the elapsed time measured by the measurement unit 14 reaches a predetermined time. The predetermined time is set to a time obtained by adding a predetermined margin to the average time required from the start to the end of the maintenance operation, for example, as in the above-described embodiments 2 and 4.
Next, the operation of the maintenance work support system for an elevator according to the present embodiment will be described with reference to fig. 12. Fig. 12 is a flowchart showing an example of the operation of the maintenance work support system for an elevator according to the present embodiment, and shows an example of a processing procedure relating to the switching between the validity and invalidity of the abnormality report. The processing from step S601 to step S604 in fig. 12 is the same as that in embodiment 3 described above (the processing from step S401 to step S404 in fig. 8), and therefore, the description thereof is omitted.
In the present embodiment, when closing of the cover 101 is detected in a state where the invalidation switch 20 is not operated to the closing side, that is, the abnormality report holding of the abnormality report part 11 is invalidated (yes in step S604), the measurement part 14 starts measuring the elapsed time (step S605), and the notification part 12 performs the notification operation (step S606). Thereafter, the automatic validation unit 16 determines whether or not the elapsed time measured by the measurement unit 14 has reached a predetermined time (step S607). When the elapsed time measured by the measurement unit 14 reaches a predetermined time (yes in step S607), the automatic validation unit 16 switches the abnormality report of the abnormality report unit 11 from invalid to valid (step S608).
As described above, the maintenance work support system for an elevator according to the present embodiment measures the elapsed time from the detection of the closing of the cover 101 of the housing 100 in the state where the abnormality report by the abnormality report unit 11 is invalidated, and automatically validates the abnormality report by the abnormality report unit 11 when the elapsed time reaches the predetermined time. Therefore, even if the user forgets to return the invalidation switch 20 after the maintenance operation is completed, it is possible to effectively prevent the abnormality report of the abnormality report section 11 from being left without being invalidated after the maintenance operation is completed.
In addition, the above embodiments can be combined and implemented as appropriate. For example, the elevator control device 10 according to another embodiment may also have the function of the completion determination unit 13 described in embodiment 1.
According to at least one embodiment described above, it is possible to effectively prevent the status of the abnormality report holding from being invalidated after the maintenance work is finished.
The embodiments of the present invention have been described above, but the above embodiments are presented as examples and are not intended to limit the scope of the invention. The above embodiment can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the scope equivalent thereto.
