Description

  The present invention relates to an elevator remote monitoring system including a monitoring center device that monitors whether there is an abnormality in an elevator.

  This type of elevator remote monitoring system is an elevator control device having a failure diagnosis function for diagnosing a failure of an elevator such as an elevator or an escalator, a monitoring terminal device connected to the elevator control device, and a general line to the monitoring terminal device. And a monitoring center device that monitors whether there is an abnormality in the elevator. In addition, the monitoring terminal device has a remote monitoring function for automatically reporting to the monitoring center device when the elevator status is detected by detecting the elevator status, and the monitoring center device is performing maintenance work for the lifting device. And setting means for setting the state of maintenance work for the elevator when the vehicle is in the lift.

  Therefore, a maintenance worker who performs maintenance work for the elevator receives a notification of the elevator's abnormality, and calls the maintenance worker and the operator in the monitoring center device that instructs the dispatching base before starting the work. Informs that the abnormal report notified from the monitoring terminal device is due to maintenance work, and temporarily removes the elevator from the monitoring target until the maintenance work of the elevator is completed and issues a dispatch instruction Ask not to.

  When the operator in the monitoring center device receives a notification from the maintenance worker about the start of maintenance work, the operator uses an input terminal device that displays the content of the abnormality report on the screen or instructs the sales office. Then, by setting the maintenance work state for the elevator with the setting means, the monitoring center device receives the abnormality report from the monitoring terminal device received after the maintenance work state is set as the abnormality report by the maintenance work. Are temporarily excluded from monitoring.

  Further, when the maintenance work is completed, the maintenance worker requests the operator in the monitoring center apparatus to make the elevator as a monitoring target again by means of communication such as a telephone. When the operator in the monitoring center device receives a notification from the maintenance worker about the completion of the maintenance work, the operator uses an input terminal device that displays the content of the abnormality report on the screen or instructs the sales office. By canceling the maintenance work status that has been set, the monitoring center device receives the abnormality report from the monitoring terminal device that is received after the maintenance work status is released. As a report, the elevator is to be monitored again.

  As a specific example of the prior art of such an elevator remote monitoring system, a control panel is installed in a hoistway, and a fault diagnosis function for diagnosing a fault in this control panel or when a fault occurs automatically notifies an external monitoring center device In connection with maintenance and inspection of elevators with a built-in remote monitoring function, as a lift, a terminal that allows a portable terminal device for maintenance to be detachably connected to the elevator car or landing is provided, and the portable terminal device for maintenance is connected to the terminal during maintenance inspection To set the elevator to maintenance inspection mode, disable the failure diagnosis function and remote monitoring function, and when the maintenance inspection work is finished, operate the maintenance portable terminal device to cancel the maintenance inspection mode.

The maintenance worker who has received the instruction is dispatched to the site where the abnormality has occurred and completes the elevator restoration work (S13), and continues normal monitoring of the elevator (S9). On the other hand, when the operator in the monitoring center apparatus 3 confirms that the maintenance work is being performed in step S10, it is determined that the cause of the abnormality is due to the maintenance work of the elevator, and the work setting release changing means The maintenance work status is set, and the local maintenance worker is instructed to send the work start date and time to the monitoring center apparatus 3 using the maintenance portable terminal device 5 (S14). When the monitoring center device 3 receives the work start date and time, the work setting canceling means of the monitoring center device 3 stores the received abnormality report in the storage unit 32 as a trial report based on the maintenance work. The abnormality report received on the display unit 34 is displayed as a test report by maintenance work (S15).

  And after displaying on the display part 34 of the monitoring center apparatus 3 in procedure S15, the control part 31 of the monitoring center apparatus 3 is the portable terminal apparatus 5 for maintenance or maintenance until the maintenance work of an elevator is completed, ie, a maintenance worker. Until the work completion date and time is transmitted from the input terminal device 4 to the monitoring center device 3, all the abnormality reports received from the monitoring terminal device 2 that monitors the elevator installed in the property are handled as trial reports by maintenance work ( S16). Next, when the monitoring center device 3 receives the work completion date and time from the maintenance portable terminal device 5 or the input terminal device 4, the control unit 31 of the monitoring center device 3 displays the state of the maintenance work set by the work setting release means. Release (S17) and complete the maintenance work of the elevator (S8). And the monitoring center apparatus 3 continues the normal monitoring of the said elevator (S9).

  According to the present embodiment configured as described above, it is assumed that the maintenance worker is delayed in contacting the monitoring center apparatus 3 or the operator in the monitoring center apparatus 3 forgets to set or cancel the state of the maintenance work. Even if a general error occurs, the monitoring center device 3 registers the work start date and time and the work completion date according to the work plan registered by the registration means, so that the maintenance worker can When the work start date / time is transmitted from the maintenance portable terminal device 5, the work setting release means automatically sets the state of the maintenance work of the elevator in step S4 shown in FIG. Are transmitted from the maintenance portable terminal device 5 to the work setting canceling means in step S7 shown in FIG. Since the state of the maintenance work for the elevator set is automatically released, whether the maintenance work for the elevator is actually performed from the state of the maintenance work set or released by the operator in the monitoring center device 3 Can be confirmed. Thereby, it is possible to clearly grasp whether the cause of the abnormality of the elevator reported to the monitoring center device 3 is due to the maintenance work of the elevator or whether the abnormality actually occurs in the elevator. .

  In addition, the monitoring center device 3 receives the notification of the abnormality of the elevator from the monitoring terminal device 2 while the state of the maintenance operation of the elevator is set by the setting means, so that the monitoring center device in the maintenance operation of the elevator Since the operation confirmation of the abnormality report to 3 can be performed, it can be known whether or not the abnormality report of the elevator is appropriately performed. Thereby, while being able to correctly identify the elevator abnormality report due to maintenance work, it is possible to quickly cope with the elevator abnormality and to improve the efficiency of the elevator maintenance work.

  Further, according to the present embodiment, the maintenance portable terminal device 5 or the input terminal device 4 is used when the elevator maintenance work is performed in the procedure S3 shown in FIG. 5 according to the work plan registered by the maintenance worker in the procedure S1 shown in FIG.
