Since the state signal holding unit 8 holds the signal abnormality, the communication device control circuit 9 sends the abnormality information to the receiver via the line interface circuit 6 and the telephone line. On the other hand, when the elevator car is not traveling, the state signal holding unit 8 holds the signal normal. At this time, if the elevator controller 4 goes down due to a failure or the like, the transmission cutoff detector 7 of the communication device control circuit 9 of the communication device 10
Checks that the transmission with the elevator controller 4 has been interrupted by checking the transmission interface circuit 5. However, since the state signal holding unit 8 holds the signal normal, the communication device control circuit 9 does not send out the abnormal signal or adds information indicating that the urgency is low, and the line interface circuit 6 and the telephone The abnormality information is transmitted to the receiver via the line.

When it is detected that this signal is abnormal and transmission has been interrupted, abnormal information corresponding to the holding signal is transmitted to the receiver.

Therefore, the fact that the elevator controller 4 (terminal) has gone down can be notified to the receiver in accordance with the state of the elevator, so that abnormal information corresponding to the boarding state of passengers in the elevator car can be transmitted to the receiver. . For this reason,
The receiver can easily distinguish between emergency information with high urgency and passengers in the elevator car or abnormal information with low urgency when no passengers are on the elevator car. it can. As a result, it is also possible to transmit only highly urgent abnormality information to the receiver.

5 is a flowchart showing an operation of the elevator remote monitoring device according to the second embodiment of the present invention.

In the figure, first, in step S1, the communication device control circuit 9 of the communication device 10 sets a timer, and in step S2, the transmission cutoff detecting section 7 determines whether or not signal transmission with the elevator control device 4 is cut off. If the signal is detected and the transmission of the signal is normal without interruption, the process returns to step S1. If the signal transmission is interrupted, the process proceeds to step S3, where it is determined whether or not the state signal holding unit 8 holds a signal abnormality. If the signal signal is held normal, the process returns to step S1. If the signal abnormality is held, the process proceeds to step S4, and it is determined whether the transmission interruption state of the signal has passed a predetermined time and the time has expired.

If is not normal, the process returns to step S6. If the transmission is normal, proceed to step S8,
It is determined whether or not the normal transmission state of the signal has elapsed and the time has elapsed since a predetermined time has elapsed. If the time has not elapsed yet, the process returns to step S7. To send to. By this series of processing, the transmission of the abnormal information to the receiver is performed after the transmission cutoff state has elapsed for a predetermined time, and the recovery information is transmitted to the receiver when the normal transmission of the signal continues for a predetermined time after the transmission of the abnormal information. Sent out.

As described above, the remote monitoring device for an elevator according to the present embodiment includes a status signal transmitting section 2 as signal transmitting means similar to that of the first embodiment and a transmission cutoff detecting section 7 as transmission cutoff detecting means. In addition to having a state signal holding unit 8 as a state signal holding unit and a communication device control circuit 9 as an abnormality information sending unit, the communication device control circuit 9 (abnormal information sending unit)

It is detected that this signal is abnormal and transmission has been interrupted, and after a predetermined time has elapsed, abnormal information corresponding to the holding signal is transmitted to the receiver, and after transmitting this abnormal information, the elevator controller 4 ( When the normal transmission of the signal between the terminal device and the communication device 10 continues for a predetermined time, the recovery information is sent to the receiver.

Therefore, similarly to the first embodiment, the fact that the elevator controller 4 (terminal) has gone down can be notified to the receiver in accordance with the state of the elevator. The receiver can easily discriminate whether the abnormal information is low. In addition, when normal transmission of signals between the elevator controller 4 (terminal) and the communication device 10 is performed, restoration information is sent to the receiver, and it is received that the elevator controller 4 has recovered its function normally. Since the receiver can be notified, the receiver can easily recognize the restoration.
Further, in this embodiment, since the abnormality information is transmitted to the receiver after a predetermined time has elapsed, the abnormality information is not transmitted at the moment of an instantaneous power failure. Since the information is transmitted, no recovery information is transmitted at the time of instantaneous recovery. As a result, the notification of the error and the recovery due to the error decreases, and the reliability of the notification of the error and the recovery increases.

By the way, the set value of the timer in the above embodiment is set to be equal to or less than the rise time of the power-on of the elevator controller 4 and equal to or longer than the instantaneous power cut-off time. If the elevator controller 4 goes down immediately after rising after the transmission, the recovery information and the abnormality information may be transmitted to the receiver.
