The invention provides a remote monitoring system capable of sending abnormal information of equipment to a monitoring center device quickly through a satellite line. In the remote monitoring system, a plurality of monitoring terminals monitoring abnormity of equipment and informing abnormity through wireless IP communication are provided with wireless communication devices capable for wireless LAN communication. A service vehicle used by maintenance workers for field operation of equipment provided with the monitoring terminal devices includes a wireless LAN communication device used for performing LAN communication with the monitoring terminal devices; a monitoring terminal database recording data required for visiting the monitoring terminal devices; and a satellite communication device sending wireless LAN data obtained through wireless LAN communication with the monitoring terminal devices through the communication satellite to the monitoring center device.
Description
technical field [0001] The present invention relates to a remote monitoring system focusing on response to large-scale disasters such as earthquakes and floods. Background technique [0002] In the remote monitoring system that remotely monitors the operation status of multiple elevators such as elevators and escalators scattered over a wide area, the operation of the elevator is incorporated into each elevator such as the elevator and escalator that is the monitoring target. A monitoring terminal device whose status is constantly monitored. And, this monitoring terminal device is connected to a monitoring center device installed in a large city via a public communication line of a telephone company. If the monitoring center device receives abnormality occurrence information from the monitoring terminal monitoring elevators, escalators, etc., it will display the abnormality occurrence information and the information of the abnormal elevator on the display device, thereby ar...
