Referring to the operation and operation of the embodiment of the present invention configured as described above are as follows.

Once the reception host 308a receives a status signal or an error occurrence signal output from a monitoring terminal device of each region (region 1 to region n) at regular time intervals, the reception host 308a connects it to the interface host 302 through the interface unit 302. After receiving the contents, the contents are stored in the internal storage means (not shown), and the reception unit 303 notifies the registration host 309 that a status signal or an abnormal signal has been received.

Then, the registration host 309 reads the contents (reception items) stored in the storage means built in the reception hosts 308a to 308b itself, and registers them in the database 305 after interpretation.

That is, it is determined whether the received content is an abnormal signal or a steady state signal.

Therefore, if it is determined whether to update the failure alarm device 307 according to the registration result and notifies it to the alarm management unit 306, the alarm management unit 306 is connected through a communication network (LAN or WAN) connected to each region. All failure alarm devices 307a, 307b, and 307c are notified and managed of the most recent elevator status.

As described above, the remote monitoring apparatus and method of the present invention can separate unnecessary reception and registration hosts dedicated to the reception and registration of the elevator status, so as to perform specialized tasks, thereby preventing unnecessary duplication and monitoring. By separating the process of receiving an external influence such as database registration and the process of receiving from the terminal device, even when the device is down by the external environment, the reception from the monitoring terminal device can continue.
