LIGHT EMISSION MACHINE CONTROL DEVICE FOR RAIL, AND LIGHT EMISSION MACHINE CONTROL SYSTEM FOR RAIL

摘要

PROBLEM TO BE SOLVED: To prevent error detection of disconnection at the time of output change-over.;SOLUTION: When a light emission command for visual confirmation is inputted, a relay 93-a is switched ON, and continuously, a relay 94-a is switched ON. Then, a relay contact 94-b-3 of a bypass circuit is connected, and an output of a reverse current from a red light emission control part 82 is bypassed. Thereafter, relay contacts 96-b-1 and 96-b-2 are changed over, and a signal is outputted from a light emission control part 83 for visual confirmation. Upon the light emission command for visual confirmation is terminated, the relay 93-a is switched OFF, the relay contact 93-b-2 is opened and a relay 96-a is switched OFF, and the relay contacts 96-b-1 and 96-b-2 are changed over so that a signal from the red light emission control part 82 is outputted. However, the relay 94-a is not switched OFF during discharging of a CR circuit 95, the relay 94-a is switched OFF after termination of electrical discharging, and the relay contact 94-b-3 is opened, whereby a signal from the red light emission control part 82 is outputted.;SELECTED DRAWING: Figure 10;COPYRIGHT: (C)2016,JPO&INPIT
