<P>PROBLEM TO BE SOLVED: To provide a train operation control system capable of shortening, as much as possible, a required time for a route control device to be restored after causing some failure and stopping, and capable of being applied to both of a distributed type and a single station type. <P>SOLUTION: The train operation control system includes a train operation control network 2 and a route control device 3A that is installed at each interlocking station and that controls train routes. The route control device 3A at each interlocking station has a route control unit 5A for main system that controls routes of an own interlocking station and a route control unit 6A for sub system that controls routes of other interlocking stations. A dual type route control unit of the route control device 3A is configured to lie astride the route control device 3A installed at the own interlocking station and a route control device 3B installed at any other interlocking station. The route control device 3A includes a virtualizing unit 4A. The dual type route control units 5A, 5B for main and sub systems monitor the presence of mutual failure through the train operation control network 2 and the virtualizing unit 4A. When some failure occurs in the route control unit 5A for main system, the route control unit 5B for sub system is switched to that of main system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
