EMERGENCY BRAKE PROTECTING CIRCUIT IN ATS POWER OFF OF A RAIL-LOAD CAR

摘要

The present invention provides an emergency braking prevention circuit when the ATS power is cut off to prevent the braking operation when the ATS power is cut off in the automatic traffic system (ATS) control circuit of a railway vehicle. It is about.;The circuit of the present invention analyzes the control signal transmitted through the connection box when the power is applied to the ATS RECEIVER 24 while the ATS circuit breaker (ATSN) is turned on, and then the driving state of the vehicle. In the ATS (ATS DISPLAY) 26 to display the railroad vehicle automatic operation system to enable automatic operation of the railway vehicle, the first emergency brake relay (EmR1) to the fast-acting receiver 24 Is connected, the b contact of the first emergency braking relay (EmR1) is connected to the line 722 that is introduced through the ATS circuit breaker (ATSN), and in series with the b contact of the first emergency braking relay (EmR1). An ATS breaking relay (ATSCR) is connected, and an emergency braking relay (EmBR) is connected to the power line (1a) through a contact of the ATS breaking relay (ATSCR) so that the first emergency braking relay (EmR1) in the emergency If so, the ATS breaking relay is excited accordingly. In addition, the emergency braking relay (EmBR) is excited and the emergency braking is engaged. When the ATS circuit breaker (ATSN) is turned off during towing, the ATS breaking relay (ATSCR) is demagnetized and the emergency braking relay (EmBR) is decompressed. Emergency braking is released.
