<P>PROBLEM TO BE SOLVED: To support line recovery in a remote control monitoring system of digital radio transmission. <P>SOLUTION: There is provided a line recovery support method when a monitoring line fails, in the remote control system in a system for transmitting a signal through digital radio transmission from a base station to a main station via a radio transmission line. The method performs line recovery by automatically controlling a facility apparatus in the base station and a facility apparatus in the main station in a system in which monitoring information from the base station is transmitted to the main station via a radio transmission means, that is, a radio transmission line. In the line recovery, a line recovery request is transmitted from the main station to the base station using a control line of the remote control monitoring system, and the monitoring information of the facility apparatus of the main station is used in estimating the cause of the line failure. <P>COPYRIGHT: (C)2010,JPO&INPIT |
