The invention discloses a control circuit for metro vehicle brake applying and relieving signals, which comprises a plurality of brake control main valves and brake control auxiliary valves, a first/tail section compartment with a cab is controlled by a first brake control main valve and a first brake control auxiliary valve, and a compartment with a pantograph is controlled by a second brake control auxiliary valve and a third brake control auxiliary valve. The carriage without the pantograph is controlled by a fourth brake control auxiliary valve and a second brake control main valve; output brake applying/releasing contacts of the brake control main valves and the brake control auxiliary valves are connected in series in a power supply circuit of a brake applying relay; and the brake non-release signal output end of each brake control main valve is connected with the brake release relay. The circuit is not provided with a cab activation relay, so that the applying/relieving signal does not need to be activated and associated with the cab, a brake applying relay and a brake relieving relay do not need to be arranged in each carriage, the number of relays is greatly reduced, the failure rate is reduced, and the reliability is improved.
本发明公开了一种地铁车辆制动施加和缓解信号的控制电路,包括多个制动控制主阀和制动控制辅阀,首/尾节带司机室车厢由第一制动控制主阀和第一制动控制辅阀控制,带受电弓车厢由第二制动控制辅阀、第三制动控制辅阀控制,不带受电弓车厢由第四制动控制辅阀、第二制动控制主阀控制;各制动控制主阀和制动控制辅阀的输出制动施加/缓解触点均串联在制动施加继电器的供电线路中;各制动控制主阀的制动不缓解信号输出端均与制动缓解继电器连接。该发明的电路不设置司机室激活继电器,使得施加/缓解信号无需与司机室激活关联,且无需在每节车厢设置制动施加继电器和制动缓解继电器,大大减少了继电器的数量,降低了故障率,提高了可靠性。
