Description

  The present invention relates to an elevator apparatus capable of reliably performing a diagnostic operation after an earthquake even if an earthquake occurs while the elevator is stopped, and an elevator control method.

  When the elevator is not used for a long period of time, the elevator administrator generally stops the elevator from the viewpoint of power saving and security. Here, “the elevator is at rest” means a state in which various operations in the elevator are stopped and service cannot be performed. In addition, as a factor that causes the elevator to stop, there may be a case where the power supply in the control panel that controls the operation of the elevator is cut off due to an operation of the administrator, a power failure, or the like.

  In addition, as a prior art of an elevator device, a periodic diagnosis operation for periodically diagnosing whether or not various types of elevator equipment normally operate, for example, a power failure occurred when a user was present during the periodic diagnosis operation, There has been proposed a system in which a periodic diagnosis operation is performed again in response to a command from an external monitoring center when the elevator cannot be performed for some reason, such as during an elevator stop (see, for example, Patent Document 1).

Embodiment 1 FIG.
FIG. 1 is a system configuration diagram of an elevator apparatus according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 designates various elevator equipment, normal operation of the elevator, rescue operation to rescue passengers in a car (not shown) after the earthquake occurs, and after the occurrence of the earthquake, before returning to normal operation, A control panel 2 for controlling various operations such as a diagnostic operation after an earthquake for diagnosing whether or not various devices normally operate. The control panel 2 is connected to the control panel 1 through a communication line, and operates even when the elevator is not operating. The alarm device 3 configured as described above is connected to the control panel 1 and the notification device 2 via a communication line, and outputs an earthquake occurrence information to the control panel 1 and the notification device 2 when the occurrence of an earthquake is detected, Reference numeral 4 denotes an external monitoring center which is connected to the notification device 2 via a telephone line or the like and remotely monitors the elevator device via the notification device 2.

  5 and 6 are elevator operation states, that is, elevator operation states, that is, operation state control means for controlling the suspension or release of the elevators, 5 is an operation panel installed in a car, 6 is a landing, etc. The key switch installed in is shown. In other words, the elevator administrator can put the elevator into a dormant state or cancel the elevator dormant state by operating the operation panel 5 or the key switch 6. Reference numeral 7 denotes a detection device that detects whether or not an elevator maintenance worker is performing maintenance work, for example, from the ON-OFF state of a maintenance switch (not shown) provided in the control panel 1. Detect whether maintenance work is in progress. The maintenance switch refers to a switch for switching the elevator to the maintenance operation mode when the maintenance worker performs the maintenance work.

  Here, the notification device 2 includes a determination unit 8 that determines whether or not the elevator is inactive when an earthquake is detected by the earthquake detector 3, and the elevator that is inactive by the determination unit 8. Is connected to the external monitoring center 4 and the command means 9 for instructing the control panel 1 to execute the diagnostic operation after the earthquake when the elevator rest state is released. A reporting means 10 for issuing various information to the center 4 and receiving various commands from the monitoring center 4 is provided. For example, when the determining unit 8 determines that the elevator is not operating, the reporting unit 10 has not performed diagnostic operation after the earthquake because the elevator is not operating to the monitoring center 4. When a diagnosis operation after an earthquake is performed by the control panel 1 that has received a command from the command means 9, the monitoring center 4 is notified of the result of the performed diagnostic operation. Or when the maintenance device inspection work is detected by the detection device 7 after the determination means 8 determines that the elevator is inactive and before the suspension state is released, the maintenance center 4 Or reports that inspection work has been carried out.

  Next, the operation of the elevator apparatus in the first embodiment of the present invention during an earthquake will be described based on the flowchart shown in FIG. In FIG. 2, when an earthquake occurs in an area equipped with an elevator device, the earthquake shake (occurrence) is detected by the earthquake detector 3, and the earthquake occurrence information is transmitted from the earthquake detector 3 to the control panel 1 and the notification device 2. Is output (step S101). In the reporting device 2 in which the earthquake occurrence information is acquired from the earthquake detector 3 and the occurrence of the earthquake is notified (step S102), first, whether the elevator is at rest by the determination means 8 provided in the reporting device 2 or not. It is determined whether or not (step S103). The determination by the determination means 8 is performed by, for example, inputting information indicating that the elevator is inactive by operating the operation panel 5 or by operating the key switch 6. If the information indicating that the elevator is not in operation due to the occurrence of a power failure or the like and the power supply in the control panel 1 being cut off is input, or if the elevator is not inactive This is performed based on whether information to be input is input.

  And when it is determined by the determination means 8 that the elevator is not at rest, the command means 9 provided in the notification device 2 gives a command to carry out a diagnostic operation after the earthquake to the control panel 1 ( After the earthquake detector 3 is reset (step S104), the diagnostic operation after the earthquake is performed by the control panel 1 (step S106). When the determination means 8 determines that the elevator is not at rest, the command means 9 in the notification device 2 does not execute the above command to the control panel 1, and the earthquake occurrence information is received from the earthquake detector 3. You may comprise so that the diagnostic operation after an earthquake may be implemented by the judgment of the input control panel 1. FIG.

  On the other hand, when it is determined by the determination means 8 that the elevator is inactive, the notification means 10 provided in the notification device 2 notifies the monitoring center 4 after the earthquake because the elevator is inactive. The fact that the diagnostic operation is not performed is issued (step S107). When the information indicating that the diagnostic operation after the earthquake is not performed because the elevator is not operating is input, the monitoring center 4 requests the dispatch of an elevator maintenance staff or the like as necessary.

  Further, in the reporting device 2, after the reporting means 10 notifies the monitoring center 4 that the elevator is not in operation, the diagnostic operation after the earthquake is not performed, and then the inspection device 7 performs inspection work by the maintenance staff. It is detected whether or not information indicating that has been implemented is input (step S108). Then, after the determination means 8 determines that the elevator is at rest in step S103, when the detection device 7 detects an inspection operation by the maintenance staff, the notification means 10 in the notification device 2 In response, the fact that the inspection work by the maintenance staff has been performed is reported (step S109). Here, the detection of whether or not the inspection work by the maintenance staff has been carried out is performed by determining that the maintenance switch has been turned ON after the determination means 8 determines that the elevator is inactive, and before the suspension state is released. This is done based on Since the maintenance switch is operated by maintenance personnel, the above content can be obtained, for example, by maintenance personnel dispatched at the request of the monitoring center 4 or maintenance personnel patroling each elevator apparatus after the occurrence of an earthquake. It is assumed that inspection work is performed.

  Then, after it is determined by the determination means 8 that the elevator is not in operation, when the maintenance operation is not performed and the elevator is released from the inactive state (step S110), the notification device 2 causes the elevator to stop. Is released, and the command means 9 in the reporting device 2 instructs the control panel 1 to execute the diagnostic operation after the earthquake (step S104). Then, after the earthquake detector 3 is reset (step S105), the post-earthquake diagnostic operation is performed by the control panel 1 that has received a command from the command means 9 (step S106). In addition, when the diagnostic driving after the earthquake is successful (step S111), after starting the normal service of the elevator (step S112), the reporting means 10 in the reporting device 2 sends the monitoring center 4 to the monitoring center 4. The result (success) of the diagnostic driving is issued (step S113). On the other hand, when the diagnostic operation after the earthquake is not successful (step S111), the normal service of the elevator is not started, and the diagnostic operation after the earthquake is performed from the reporting means 10 in the reporting device 2 to the monitoring center 4. Result (failure) is issued (step S113).

  According to the first embodiment of the present invention, even if a diagnosis operation after the earthquake is not started immediately after the earthquake because an earthquake occurred during the suspension of the elevator, Before returning to operation, diagnostic operation after an earthquake is surely implemented. In addition, when an earthquake occurs while the elevator is not operating, the reporting means 10 in the reporting device 2 notifies the monitoring center 4 that the elevator is not operating and the diagnostic operation after the earthquake has not been performed. Therefore, the monitoring center 4 can immediately understand the reason why the result of the diagnostic operation after the earthquake is not issued, and can take an optimum action according to the information that has been issued. In other words, when the elevator is not in operation, it is unlikely that passengers will be trapped in the car even if an earthquake occurs. Therefore, when dispatching maintenance personnel, give priority to other elevator devices that require urgent action. It is possible to efficiently carry out rescue and recovery activities later.

  In addition, when the diagnosis operation is performed after the occurrence of the earthquake, since the result of the diagnosis operation after the earthquake is issued from the reporting means 10 in the reporting device 2 to the monitoring center 4, the monitoring center 4 It is also possible to take appropriate measures based on the reported diagnostic driving results. In addition, since there is no need for instructions from the external monitoring center 4 when conducting diagnostic operations after an earthquake, it is easy to respond to wide-area disasters such as earthquakes, and each elevator device can reliably perform diagnostic operations after an earthquake. Can be implemented.

  In the first embodiment, the determination means 8, the command means 9, and the notification means 10 are all provided in the notification device 2. However, even if the determination means 8 and the command means 9 are separate devices, the elevator is stopped. Needless to say, the same effects as those of the first embodiment can be obtained as long as the operation is possible.
