If the signal is detected and the signal transmission is normal rather than interrupted, the process returns to step S1. If the signal transmission is interrupted, the process proceeds to step S3, and it is determined whether the status signal holding unit 8 holds the signal abnormality. If the 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 or not the transmission interruption state of the signal has timed out for a predetermined time. If it is not timed yet, the process returns to step S2 to perform the above process. When the time is over, the process proceeds to step S5, and the abnormality information is sent to the receiver. After that, the timer is set again in step S6, and in step S7 the transmission cutoff detection unit 7 determines whether the transmission cutoff state of the signal with the elevator controller 4 is recovered and the transmission has become normal, and the transmission is still performed. 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 passed a predetermined time and the time has passed. If the time has not passed yet, the process returns to step S7. Send to. Through this series of processing, the abnormal information is sent to the receiver after the transmission is interrupted for a predetermined time, and after the abnormal information is sent, the recovery information is sent to the receiver when the normal signal transmission continues for the predetermined time.

It is possible for the receiver side to easily distinguish whether the abnormal information is low. Moreover, when the signals between the elevator controller 4 (terminal) and the communication device 10 are normally transmitted, restoration information is sent to the receiver, and it is received that the elevator controller 4 has normally recovered its function. Since the receiver can be notified, the receiver can easily recognize the restoration.
Further, in the present embodiment, since the abnormality information is sent to the receiver after a lapse of a predetermined time, the abnormality information is not sent during the momentary power failure, and even when the abnormality is recovered, the abnormality information is restored after the lapse of the predetermined time. Since the information is transmitted, the restoration information is not transmitted during the momentary restoration. As a result, the notification of abnormalities and restorations due to errors is reduced, and the reliability of notifications of abnormalities and restorations is increased.

When the elevator controller 4 starts up immediately after being sent out and then immediately goes down, the restoration information and the abnormality information may be sent to the receiver.

を受信機側で容易に区別することができる。As described above, the elevator remote monitoring apparatus according to the invention of claim 1 is provided with the signal transmitting means, the transmission interruption detecting means, the status signal holding means, and the abnormality information transmitting means, and the terminal. A fixed signal is always sent from the device to the communication device, this signal is held by the communication device, and when it is detected that this signal has an interruption due to an error, the error information according to the held signal is sent to the receiver. By doing so, it is possible to notify the receiver that the terminal has gone down according to predetermined conditions, so that it is possible for the receiver side to easily distinguish between abnormal information with high urgency and abnormal information with low urgency. it can.

旧の通知の信頼性が高い。According to a second aspect of the present invention, there is provided an elevator remote monitoring apparatus having the same signal transmitting means as that of the first aspect of the invention, a transmission interruption detecting means, a status signal holding means, and an abnormality information transmitting means. In addition, an abnormal information transmission delay means and a recovery information transmission means are provided, and a predetermined signal is constantly transmitted from the terminal device to the communication device, the communication device holds this signal, and this signal is abnormal and the transmission is cut off. When the transmission interruption state is detected for a predetermined time, abnormal information corresponding to the hold signal is sent to the receiver, and after the abnormal information is sent, the normal signal of the terminal and the communication device is transmitted. By sending the restoration information to the receiver when the transmission continues for a predetermined time,
Similar to the invention of claim 1, since the receiver can be notified that the terminal is down according to a predetermined condition, the receiver side can determine whether the abnormal information is highly urgent or the abnormal information is less urgent. It can be easily distinguished, and the receiver can be notified of the restoration of the abnormality without sending the abnormality information at the moment of a power failure, so the receiver can easily recognize the restoration and notify the abnormality and the restoration. High reliability.
