At the same time, it has a function of disconnecting this line when communication is completed. Here, the remote notification devices 12a to 12g of the parent building 14a, the child buildings 14b to 14g, and the monitoring center 6 are connected via telephone lines 16a to 16h and the public line network 8. The public line network 8 connects and disconnects lines so that the remote reporting devices 12a to 12g and the monitoring center 6 of the parent building 14a and the child buildings 14b to 14g communicate with each other.

  The parent building 14a and the child buildings 14b to 14g are buildings provided with remote notification devices 12a to 12g and an elevator system for guiding passengers to a predetermined floor. The parent building 14a is further provided with a seismic detector 20, which is a device that senses an earthquake. When a seismic level of a predetermined level (for example, seismic intensity 3) or higher is detected, an earthquake has occurred. And the remote notification device 12a of the parent building 14a is notified.

  The telephone lines 16 a to 16 h are subscription lines connected to the public line network 8. The network 18 is a wireless LAN (Local Area Network) constructed so that communication using radio waves is performed between the remote notification devices 12a to 12g provided in the parent building 14a and the child buildings 14b to 14g.

  Next, the operation of the remote monitoring system 10 having the above configuration will be described with reference to FIG. 1 and FIG. FIG. 2 is a flowchart showing the operation of the remote monitoring system 10. In the remote monitoring system 10, the earthquake detector 20 provided in the parent building 14a determines whether or not an earthquake of a predetermined earthquake level (for example, seismic intensity 3) or more has occurred (S2). If it is not determined that there has been an earthquake exceeding the predetermined earthquake level, the process returns to S2. If it is determined that there is an earthquake of a predetermined earthquake level or higher, the process proceeds to S4.

  The remote reporting device 12a of the parent building 14a that has received a notification from the earthquake detector 20 that there has been an earthquake dials with the monitoring center 6 as the communication partner and quickly secures a communication line in the public line network 8 for monitoring. Communication with the center 6 is possible (S4). Further, the remote notification device 12a of the parent building 14a instructs the remote notification devices 12b to 12g of the child buildings 14b to 14g via the network 18 to restrict communication functions using the telephone lines 16b to 16g. (S6).

  The remote notification device 12a of the parent building 14a acquires failure information and the like of the parent building 14a, and also acquires failure information and the like of each child building 14b to 14g from each of the remote notification devices 12b to 12g via the network 18 (S8). ). Then, the remote notification device 12a of the parent building 14a sends the failure information and the like of the parent building 14a and each of the child buildings 14b to 14g to the monitoring center 6 via the telephone line 16a, the communication line in the public line network 8, and the telephone line 16h. (S10).

  The remote notification device 12a of the parent building 14a determines whether or not a predetermined time (for example, 10 minutes) has elapsed since the communication line in the public line network 8 was secured (S12). If it is determined that the predetermined time has not elapsed, the process returns to S12 again. If it is determined that the predetermined time has elapsed, the process proceeds to S14.

  The remote notification device 12a of the parent building 14a determines whether or not failure information of all the buildings of the parent building 14a and the child buildings 14b to 14g has been transmitted to the monitoring center 6 (S14). If it is determined that the transmission of the failure information of all the buildings of the parent building 14a and the child buildings 14b to 14g is completed, the process proceeds to S18. If it is determined that transmission of failure information of all the buildings of the parent building 14a and the child buildings 14b to 14g is not completed, a list of buildings that cannot be transmitted is created and the list information is transmitted to the monitoring center 6. (S16).

  The remote notification device 12a of the parent building 14a disconnects the secured communication line of the public line network 8 (S18). Thus, when a disaster such as an earthquake occurs, only the parent building 14a can quickly secure a communication line in the public line network 8. Moreover, congestion of the public line network 8 can be prevented by restricting the reporting function of each of the remote reporting devices 12b to 12g of the child buildings 14b to 14g. Further, the parent building 14a and the child buildings 14b to 14g are connected by the network 18 to be grouped. This makes it possible to acquire failure information and the like collected in groups, so that a maintenance worker can easily dispatch.
