OPERATION DIRECTION CONTROLLER

摘要

PROBLEM TO BE SOLVED: To improve maintainability and environmental resistance in an operation direction controller for securing automatic blocking in a single line zone. SOLUTION: A master device 20 is arranged at the station of one end side of a single line zone, slave devices 30 and 40 are arranged at the station of the other end side and between the two stations, and these devices are interconnected by a transmission line 50. The master device 20 collects information necessary for operation direction control from an external unit 60 connected to its own device and the slave devices 30 and 40 through the transmission line 50, executes an operation direction control logic for automatic closing in a single line zone based on the collected information, and sends out control data thereby obtained to the external unit connected to each slave device or the self device. Thus, an automatic blocking operation in the single line zone is controlled in a concentrated manner from the master device 20.
