Description

  Embodiments described herein relate generally to an elevator maintenance work support system.

  An elevator is a facility in which ensuring safety is extremely important, and maintenance work is periodically performed to ensure this. The maintenance work of the elevator includes an operation of confirming the operation in a state where the abnormality is intentionally detected in a state where no abnormality actually occurs. In general, elevators are provided with a function to issue an abnormality when an abnormality is detected. However, when an abnormality is intentionally detected during maintenance work, the elevator may not issue an abnormality. desired. Therefore, a switch for switching between enabling / disabling of the abnormal alarm is provided, and when performing maintenance work of the elevator, the operator can invalidate the abnormal alarm by operating this switch.

  However, since this switch is manually operated by an operator, forgetting to return the switch may occur after the maintenance work is completed. If the abnormal notification is left invalidated due to forgetting to return the switch, there is a concern that even if an abnormality occurs during normal operation of the elevator, an abnormality is not generated but a problem occurs.

  Hereinafter, an elevator maintenance work support system according to an embodiment will be described in detail with reference to the accompanying drawings. In the following description, components having similar functions are denoted by the same reference numerals, and repeated description is omitted as appropriate.

<First Embodiment>
First, the configuration of the elevator maintenance work support system according to the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the first embodiment, and FIG. 2 is a perspective view of a housing provided with a disabling switch.

  As shown in FIG. 1, the elevator maintenance work support system according to the present embodiment performs an elevator maintenance work for an elevator control device 10, an invalidation switch 20, a cover close detector 30, and an elevator provided as an elevator installation. And a worker terminal 50 operated by a worker who performs the operation.

  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, for example, by a processor included in a microcomputer in the elevator control device 10 executing a predetermined program, that is, by software. Further, all or a part of these functional components may be configured by dedicated hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). Further, these functional components may be realized by a device different from the elevator control device 10 (outside the elevator control device 10).

  When an abnormality in the elevator is detected, the abnormality notification unit 11 issues a notification (abnormality notification) to notify a predetermined external notification destination that an abnormality has occurred. The external notification destination is, for example, a terminal of an administrator room that manages elevator facilities, or a monitoring panel of a service information center when an elevator remote maintenance contract is concluded.

  The invalidation switch 20 is a switch for switching the validity / invalidity of the abnormality reporting by the abnormality reporting unit 11 according to the operation of the worker who performs the maintenance work. The invalidation switch 20 is provided, for example, in a hall maintenance device installed in a hall on a predetermined floor. As shown in FIG. 2, the hall maintenance device includes a housing 100 having a cover 101 that can be opened and closed by a maintenance worker by key operation or the like. The invalidation switch 20 is disposed inside the casing 100 together with other switches operated during maintenance and inspection. Other switches include, for example, a switch that switches the elevator operation mode to the inspection mode, and a switch that permits control of the elevator by the worker terminal 50 operated by the worker.

  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 a worker who performs maintenance work, the abnormality reporting by the abnormality reporting unit 11 is invalidated, and when operated to the off side (NOR side), an abnormality occurs. Notification is activated. Usually, a worker who performs maintenance work operates the invalidation switch 20 to the ON side before starting the maintenance work to invalidate the abnormality reporting by the abnormality reporting unit 11, and when the maintenance work is finished, the invalidation switch 20 Is returned to the off side to enable the abnormal alarm, but there is a case where the invalidation switch 20 is forgotten to return.

  The cover close detector 30 detects the closed state of the cover 101 of the housing 100 that houses the invalidation switch 20. The cover close detector 30 may be configured to detect the closed state of the cover 101, and an arbitrary method such as a mechanical method, an electric method, or an optical method can be used as the detection method. The cover close detector 30 sends a detection signal that becomes active when the cover 101 is in the closed state to the elevator control device 10. Thereby, the elevator control device 10 can recognize whether the cover 101 of the housing 100 that houses the invalidation switch 20 is in an open state or a 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 close detector 30 detects the closed state of the cover of the casing of the elevator control device 10.

  The notification unit 12 is a casing 100 that houses the invalidation switch 20 in a state where the abnormal reporting by the abnormal reporting unit 11 is invalidated, that is, in a state where the invalidating switch 20 is operated to the on side. When the cover close detector 30 detects that the cover 101 is closed, a predetermined notification operation is performed. The notification operation here is an operation for notifying the operator who has performed the operation of closing the cover 101 that the disabling switch 20 has not been returned to the OFF side, such as a buzzer sounding. . Note that the notification operation may be any operation that allows the worker to be aware, and in addition to the buzzer sounding, various operations such as lighting of a warning light, blinking, output of an audio announcement, display of a message, and the like can be applied.

  The worker terminal 50 is a terminal that is operated when the worker carries and performs maintenance work. The worker terminal 50 is connected to the elevator control device 10 by wire or wirelessly and communicates with the elevator control device 10. In the present embodiment, when the worker finishes the maintenance work, the worker terminal 50 is operated to send a notification to the elevator control device 10 that the maintenance work is finished. The worker 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 in which application software for maintenance work is installed. In the present embodiment, it is assumed that the worker terminal 50 directly communicates with the elevator control device 10, but when the remote maintenance contract of the elevator is concluded, the worker terminal 50 is the service information center. The structure which communicates indirectly with the elevator control apparatus 10 via a server etc. may be sufficient.

  The completion determination unit 13 is configured such that the abnormality reporting by the abnormality reporting unit 11 is valid, and the cover 101 of the housing 100 that houses the invalidation switch 20 by the cover closing detector 30 is in a closed state. When a notification (maintenance operation end notification) is received from the worker terminal 50 in the detected state, it is determined that the maintenance operation has been completed. That is, when the completion determination unit 13 receives the maintenance work end notification from the worker terminal 50, after confirming that the invalidation switch 20 is correctly returned to the off side and the cover 101 is closed, It is determined that the maintenance work has been completed. In other words, even if a maintenance work end notification is received from the operator terminal 50, if the disabling switch 20 remains operated or the cover 101 remains open, the maintenance work is completed. Not judged. The completion of the maintenance work is recorded as a log, for example. In addition, when the completion of the maintenance work is confirmed, a work report of the maintenance work may be created.

  Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIGS. 3 and 4. 3 and 4 are flowcharts showing an operation example of the elevator maintenance work support system according to the present embodiment, and FIG. 3 shows an example of a processing procedure related to switching between valid / invalid of abnormal alarming. Shows an example of a processing procedure by the completion determination unit 13.

  First, with reference to FIG. 3, a process related to switching between valid / invalid of abnormal alarm will be described. When the invalidation switch 20 is operated to the ON side by the operator who performs the maintenance work (step S101: Yes), the abnormality reporting by the abnormality reporting unit 11 is switched from valid to invalid according to this operation (step S101). S102). If the invalidation switch 20 is not operated to the on side (step S101: No), this process ends as it is.

  Thereafter, it is determined whether or not the invalidation switch 20 has been operated to the off side (step S103). If the invalidation switch 20 has been operated to the off side (step S103: Yes), an abnormality issuance by the abnormality reporting unit 11 is performed. The information is switched from invalid to valid (step S104). On the other hand, if the invalidation switch 20 is not operated to the off side (step S103: No), whether the cover closing detector 30 detects that the cover 101 of the casing 100 that houses the invalidation switch 20 is closed. It is determined whether or not (step S105). If it is not detected that the cover 101 is closed (step S105: No), the process returns to step S103 and the determinations in steps S103 and S104 are repeated.

  On the other hand, when it is detected that the cover 101 is closed without the invalidation switch 20 being operated to the off side, that is, in a state where the abnormality reporting by the abnormality reporting unit 11 is invalidated ( In step S105: Yes), a notification operation by the notification unit 12 is performed (step S106), and a series of processing ends. By this notification operation, the worker who performs the maintenance work can notice that the disabling switch 20 is forgotten to return when the cover 101 of the housing 100 is closed.

  Next, processing of the completion determination unit 13 will be described with reference to FIG. When the completion determination unit 13 receives the maintenance work end notification from the worker terminal 50 (step S201: Yes), the completion determination unit 13 checks whether or not the abnormality notification by the abnormality notification unit 11 is valid (step S202). If the abnormality report is valid (step S202: Yes), it is confirmed whether or not the closed state of the cover 101 of the housing 100 is detected by the cover close detector 30 (step S203). Here, when it is confirmed that the abnormal alarm is valid and the closed state of the cover 101 is detected (step S203: Yes), the completion determination unit 13 determines that the maintenance work has been completed. Determination is made (step S204).

  On the other hand, when the maintenance work end notification has not been received from the worker terminal 50 (step S201: No), or when the abnormal reporting by the abnormal reporting unit 11 is invalid (step S202: No), or If the closed state of the cover 101 of the housing 100 is not detected, that is, the cover 101 remains open (step S203: No), the process ends without determining that the maintenance work is completed. .

  As described above, the elevator maintenance work support system according to the present embodiment is invalid in a state where the invalidation switch 20 is operated to the on side and the abnormal reporting by the abnormal reporting unit 11 is invalidated. When it is detected that the cover 101 of the housing 100 that houses the enable switch 20 is closed, a notification operation such as a buzzer is performed. Therefore, when the operator who performs the maintenance work finishes the maintenance work and closes the cover 101 of the housing 100 without forgetting to return the invalidation switch 20 to the off side, the operator forgets to return the invalidation switch 20 by the notification operation. The operator can be made aware and it is possible to effectively prevent the abnormal reporting by the abnormal reporting unit 11 from being left invalid after the maintenance work is finished.

  Further, according to the elevator maintenance work support system according to the present embodiment, the invalidation switch 20 is returned to the off side, the abnormal reporting by the abnormal reporting unit 11 is validated, and the invalidation switch 20 is stored. On the condition that the cover 101 of the casing 100 to be closed is closed, it is determined that the maintenance work has been completed when the maintenance work completion notification is received from the worker terminal 50. It is possible to more effectively prevent the abnormal reporting by the abnormal reporting unit 11 from being left invalidated.

Second Embodiment
Next, a second embodiment will be described. An operator who performs maintenance work may operate the invalidation switch 20 to the on side to invalidate the abnormality reporting by the abnormality reporting unit 11, and then close the cover 101 of the housing 100 and start the maintenance work. is there. At this time, a notification operation by the notification unit 12 is performed, but it is also assumed that the operator ignores this notification operation in an attempt to return the invalidation switch 20 to the off side when the maintenance work is completed. In such a case, even if forgetting to return the invalidation switch 20 occurs when the maintenance work is completed, the operator cannot be made aware of forgetting to return the invalidation switch 20.

  Therefore, in the present embodiment, the elapsed time since the detection of the closing of the cover 101 of the housing 100 in a state where the abnormal reporting by the abnormal reporting unit 11 is invalid is measured, and this elapsed time is measured. If the abnormal alarm is not activated before the time reaches the predetermined time, a 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, a worker terminal 50 carried by a worker performing maintenance work, a server of a service information center, or the like. Since other functions and operations are the same as those of the first embodiment described above, only the characteristic features of this embodiment will be described below.

  FIG. 5 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the second embodiment. In this embodiment, as shown in FIG. 5, a measurement unit 14 is added as a functional component realized in the elevator control device 10.

  In the measurement unit 14, the cover 101 of the casing 100 is closed by the cover close detector 30 in a state where the invalidation switch 20 is operated to the on side and the abnormal reporting by the abnormal reporting unit 11 is invalidated. Measure the elapsed time since this was detected.

  In addition, the notification unit 12 in this embodiment performs the notification operation similar to that in the first embodiment described above, and the invalidation switch 20 is turned off before the elapsed time measured by the measurement unit 14 reaches a predetermined time. When the abnormality reporting by the abnormality reporting unit 11 is not validated, the notification operation for the external notification destination is further performed. In this notification operation, for example, a message indicating that the invalidation switch 20 is forgotten to return is displayed on an external device, or a voice announcement indicating that the invalidation switch 20 is forgotten to return is externally provided. It is an operation of outputting from the device.

  Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the operation of the elevator maintenance work support system according to the present embodiment, and shows an example of a processing procedure related to switching between valid / invalid of abnormal alarm. Note that the processing from step S301 to step S305 in FIG. 6 is the same as that in the above-described first embodiment (processing from step S101 to step S105 in FIG. 3), and thus description thereof is omitted.

  In the present embodiment, it is detected that the cover 101 is closed without the invalidation switch 20 being operated to the off side, that is, in a state where the abnormality reporting by the abnormality reporting unit 11 is invalidated. In the case (step S305: Yes), the measurement unit 14 starts measuring the elapsed time (step S306), and the notification unit 12 performs a notification operation (step S307). Thereafter, it is monitored whether or not the invalidation switch 20 is operated to the off side (step S308). When the invalidation switch 20 is operated to the off side (step S308: Yes), the process proceeds to step S304, and an abnormality occurs. The abnormal reporting by the reporting unit 11 is switched from invalid to valid.

  On the other hand, if the invalidation switch 20 is not operated to the off side and the abnormality reporting by the abnormality reporting unit 11 remains disabled (step S308: No), the elapsed time measured by the measuring unit 14 It is determined whether or not the predetermined time has been reached (step S309). And if the elapsed time which the measurement part 14 measures has not reached predetermined time (step S309: No), it will return to step S308 and the determination of step S308 and step S309 will be repeated. On the other hand, if the invalidation switch 20 is not operated to the off side and the elapsed time reaches a predetermined time (step S308), the notification unit 12 performs a notification operation to the external notification destination (step S310), The process ends.

  As described above, in the elevator maintenance work support system according to the present embodiment, it is detected that the cover 101 of the housing 100 is closed in a state where the abnormal reporting by the abnormal reporting unit 11 is invalid. If the invalidation switch 20 is not operated to the OFF side before the elapsed time reaches a predetermined time and the abnormality reporting by the abnormality reporting unit 11 is not validated, the A notification operation is performed on the notification destination. Therefore, even if the worker who performs the maintenance work starts the maintenance work with the cover 101 of the casing 100 housing the invalidation switch 20 closed, and forgets to return the invalidation switch 20 after the maintenance work is completed. In addition, it is possible to notice that the invalidation switch 20 is forgotten to be returned, and it is possible to more effectively prevent the abnormal reporting by the abnormal reporting unit 11 from being left invalid after the maintenance work is completed.

<Third Embodiment>
Next, a third embodiment will be described. In the present embodiment, when the invalidation switch 20 is forgotten to be returned, the abnormality reporting by the abnormality reporting unit 11 can be validated by a command input from the outside of the elevator. However, in order to prevent inadvertent activation of an abnormal alarm during maintenance work, the abnormal alarm is invalidated and the cover 101 of the casing 100 is closed by the cover close detector 30. An input of an external command is permitted on condition that the state is detected. Since other functions and operations are the same as those of the first embodiment described above, only the characteristic features of this embodiment will be described below.

  FIG. 7 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the third embodiment. In the present embodiment, as shown in FIG. 7, a remote enabler 15 is added as a functional component realized in the elevator control device 10.

  In the remote enabler 15, the invalidation switch 20 is operated to the on side so that the abnormal reporting by the abnormal reporting unit 11 is invalid, and the cover 101 of the housing 100 that houses the invalidating switch 20 is provided. When an invalidation command is input from an external command source in a state in which it is detected that the cover is closed by the cover close detector 30, an abnormal alarm that is invalidated according to the invalidation command is issued. Enables abnormal reporting by the unit 11. The command source is, for example, a worker terminal 50 carried by a worker performing maintenance work, a server of a service information center, or the like.

  Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing an operation example of the elevator maintenance work support system according to the present embodiment, and shows an example of a processing procedure related to switching between valid / invalid of an abnormal alarm. Note that the processing from step S401 to step S405 in FIG. 8 is the same as that in the first embodiment described above (processing from step S101 to step S106 in FIG. 3), and thus the description thereof is omitted.

  In this embodiment, it is detected that the cover 101 is closed in a state where the abnormality reporting by the abnormality reporting unit 11 is invalidated, and after the notification operation by the notification unit 12 is performed in step S405, The remote enabler 15 monitors whether an enable command from an external command source has been input (step S406). When an enabling command is input from an external command source (step S406: Yes), the remote enabling unit 15 switches the abnormal reporting by the abnormal reporting unit 11 from invalid to valid (step S407).

  As described above, in the elevator maintenance work support system according to the present embodiment, the abnormality reporting by the abnormality reporting unit 11 is invalid, and the cover 101 of the casing 100 that houses the invalidation switch 20 is used. When an activation command is input from an external command source while it is detected that is in the closed state, the abnormal reporting by the abnormal reporting unit 11 is validated in response to the validation command. Like to do. Therefore, when the invalidation switch 20 is forgotten to be returned after the maintenance work is completed, the abnormality reporting by the abnormality reporting unit 11 can be validated by remote operation, and the abnormality reporting unit 11 after the maintenance work is completed. It is possible to more effectively prevent the abnormal notification due to being left invalidated.

<Fourth embodiment>
Next, a fourth embodiment will be described. In the present embodiment, similar to the third embodiment described above, the abnormality reporting by the abnormality reporting unit 11 can be validated by an activation command input from an external command source. As a condition for permitting the input of a command from, an elapsed time from when it is detected that the cover 101 of the housing 100 is closed in a state where the abnormality reporting by the abnormality reporting unit 11 is invalid is predetermined. The condition that the time is exceeded has been added.

  That is, in the present embodiment, as in the second embodiment described above, it is detected that the cover 101 of the casing 100 is closed in a state where the abnormality reporting by the abnormality reporting unit 11 is invalid. Measure the elapsed time. When the abnormality reporting by the abnormality reporting unit 11 is invalid and the cover closing detector 30 detects that the cover 101 of the housing 100 is closed, the measured elapsed time is When an activation command is input from an external command source after a predetermined time has elapsed, the abnormality reporting by the abnormality reporting unit 11 is validated according to the validation command. Since other functions and operations are the same as those of the first embodiment described above, only the characteristic features of this embodiment will be described below.

  FIG. 9 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the fourth embodiment. In the present embodiment, as shown in FIG. 9, a measuring unit 14 and a remote enabling unit 15 are added as functional components realized in the elevator control device 10.

  The measurement unit 14 detects that the cover 101 of the housing 100 has been closed in a state where the abnormality reporting by the abnormality reporting unit 11 is invalid, similarly to the measurement unit 14 in the second embodiment described above. Measure the elapsed time since being done.

  In the remote enabler 15, similar to the remote enabler 15 in the third embodiment described above, the abnormal reporting by the abnormal reporting unit 11 is invalid, and the cover 101 of the housing 100 is closed. When an invalidation command is input from an external command source in a state where it is detected that the fault is detected, the abnormal reporting by the abnormal reporting unit 11 is validated according to the invalidating command. However, the remote validation unit 15 in the present embodiment does not accept the input of the invalidation command until the elapsed time measured by the measurement unit 14 reaches a predetermined time, and the elapsed time measured by the measurement unit 14. After the predetermined time is exceeded, the input of the invalidation command is accepted and the abnormality reporting by the abnormality reporting unit 11 is validated. The predetermined time is set to, for example, a time obtained by adding a predetermined margin to the average time required from the start to the end of the maintenance work, as in the second embodiment.

  Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart illustrating an operation example of the elevator maintenance work support system according to the present embodiment, and illustrates an example of a processing procedure related to switching between valid / invalid of an abnormal alarm. Note that the processing from step S501 to step S504 in FIG. 10 is the same as that in the above-described third embodiment (processing from step S401 to step S404 in FIG. 8), and thus description thereof is omitted.

  In the present embodiment, it is detected that the cover 101 is closed without the invalidation switch 20 being operated to the off side, that is, in a state where the abnormality reporting by the abnormality reporting unit 11 is invalidated. In the case (step S504: Yes), the measurement unit 14 starts measuring the elapsed time (step S505), and the notification unit 12 performs a notification operation (step S506). Thereafter, it is monitored by the remote enabler 15 whether an enable command from an external command source has been input (step S507). When an enabling command is input from an external command source (step S507: Yes), it is determined whether the elapsed time measured by the measuring 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 (step S508: No), the input of the validation command from the external transmission source is not accepted, and the process returns to step S507. 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 issues an abnormality report by the abnormality report unit 11 in response to the validation command. Switching from invalid to valid (step S509).

  As described above, in the elevator maintenance work support system according to the present embodiment, the abnormality reporting by the abnormality reporting unit 11 is invalid, and the cover 101 of the casing 100 that houses the invalidation switch 20 is used. If the activation command is input from an external command source after the elapsed time after entering this state has exceeded the specified time, it is detected that the command is closed. Accordingly, the abnormality reporting by the abnormality reporting unit 11 is validated. Therefore, similarly to the above-described third embodiment, when forgetting to return the invalidation switch 20 occurs after the maintenance work is completed, the abnormality reporting by the abnormality reporting unit 11 can be validated by remote operation, It can be more effectively prevented that the abnormal reporting by the abnormal reporting unit 11 is left invalid after the maintenance work is finished.

  In particular, in the present embodiment, as a condition for permitting the input of an activation command from an external command source, the cover 101 of the housing 100 is closed in a state where the abnormal reporting by the abnormal reporting unit 11 is invalid. Since the condition that the elapsed time after the detection is detected exceeds a predetermined time is added, the abnormality notification by the abnormality notification unit 11 is made according to the activation command before the maintenance work is finished. It is possible to effectively prevent the inconvenience that is activated.

<Fifth Embodiment>
Next, a fifth embodiment will be described. In the present embodiment, when a predetermined time elapses after it is detected that the cover 101 of the housing 100 is closed in a state where the abnormality reporting by the abnormality reporting unit 11 is invalid, the abnormality reporting unit 11 Anomaly reporting is automatically activated. That is, in the present embodiment, as in the second embodiment described above, it is detected that the cover 101 of the casing 100 is closed in a state where the abnormality reporting by the abnormality reporting unit 11 is invalid. Measure the elapsed time. When the elapsed time reaches a predetermined time, the abnormal reporting by the abnormal reporting unit 11 is validated. Since other functions and operations are the same as those of the first embodiment described above, only the characteristic features of this embodiment will be described below.

  FIG. 11 is a block diagram illustrating a configuration example of an elevator maintenance work support system according to the fifth embodiment. In the present embodiment, as shown in FIG. 11, a measurement unit 14 and an automatic validation unit 16 are added as functional components realized in the elevator control device 10.

  The measurement unit 14 detects that the cover 101 of the housing 100 has been closed in a state where the abnormality reporting by the abnormality reporting unit 11 is invalid, similarly to the measurement unit 14 in the second embodiment described above. Measure the elapsed time since being done.

  When the elapsed time measured by the measurement unit 14 reaches a predetermined time, the automatic validation unit 16 validates the abnormal reporting by the abnormal reporting unit 11 that is invalidated. 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, for example, as in the second embodiment and the fourth embodiment described above.

  Next, the operation of the elevator maintenance work support system according to the present embodiment will be described with reference to FIG. FIG. 12 is a flowchart illustrating an operation example of the elevator maintenance work support system according to the present embodiment, and illustrates an example of a processing procedure related to switching between valid / invalid of an abnormal alarm. Note that the processing from step S601 to step S604 in FIG. 12 is the same as that in the above-described third embodiment (processing from step S401 to step S404 in FIG. 8), and thus description thereof is omitted.

  In the present embodiment, it is detected that the cover 101 is closed without the invalidation switch 20 being operated to the off side, that is, in a state where the abnormality reporting by the abnormality reporting unit 11 is invalidated. In the case (step S604: Yes), the measurement unit 14 starts measuring the elapsed time (step S605), and the notification unit 12 performs a 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). Then, when the elapsed time measured by the measurement unit 14 reaches a predetermined time (step S607: Yes), the automatic validation unit 16 switches the abnormality report by the abnormality report unit 11 from invalid to valid (step S608).

  As described above, in the elevator maintenance work support system according to the present embodiment, it is detected that the cover 101 of the housing 100 is closed in a state where the abnormal reporting by the abnormal reporting unit 11 is invalid. The elapsed time is measured, and when this elapsed time reaches a predetermined time, the abnormal reporting by the abnormal reporting unit 11 is automatically validated. Therefore, even if the invalidation switch 20 is forgotten to be returned after the maintenance work is completed, it is possible to effectively prevent the abnormal reporting by the abnormal reporting unit 11 from being left invalid after the maintenance work is completed. Can do.

  The above-described embodiments can be implemented in combination as appropriate. For example, the function of the completion determination unit 13 described in the first embodiment may be similarly given to the elevator control device 10 in other embodiments.

  According to at least one embodiment described above, it is possible to effectively prevent the abnormal alarm from being left invalid after the maintenance work is completed.

  As mentioned above, although embodiment of this invention was described, the above-mentioned embodiment is shown as an example and is not intending limiting the range of invention. The above-described embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
