The invention relates to a parking control system for automatic end changing of a subway engineering vehicle and a vehicle. A parking cylinder; the switching valve is provided with an air inlet, an air outlet, a pre-control port and a first exhaust port; the first electromagnetic valve is provided with an inlet, an outlet and a second exhaust port; an inlet of the first electromagnetic valve is connected to the brake cylinder, and an outlet of the first electromagnetic valve is connected to a pre-control port of the switching valve; when the first electromagnetic valve is powered off and closed, the brake cylinder is communicated with the parking cylinder through the switching valve; when the first electromagnetic valve is electrified and opened, the brake cylinder is communicated with a pre-control port of the switching valve through the first electromagnetic valve, and the parking cylinder is communicated with a first exhaust port of the switching valve; different passages in the switching valve are controlled through power gaining and power losing of the first electromagnetic valve, the situation that parking brake is relieved due to pressure rise of a brake cylinder is prevented, and therefore success of automatic end changing is guaranteed.

    本发明涉及一种地铁工程车自动换端的停放控制系统及车辆,停放系统包括:制动缸;停放缸;切换阀,其设置有进气口、出气口、预控口和第一排气口;第一电磁阀,其设置有入口,出口和第二排气口;所述第一电磁阀的入口连接至所述制动缸,所述第一电磁阀的出口连接至所述切换阀的预控口;其中,当所述第一电磁阀失电关闭时,所述制动缸通过所述切换阀与所述停放缸接通;当所述第一电磁阀得电打开时,所述制动缸通过所述第一电磁阀与所述切换阀的预控口接通,所述停放缸与所述切换阀的第一排气口接通;本发明通过第一电磁阀得失电,控制切换阀内部的不同通路,防止制动缸压力上升使停放制动被缓解,从而保证自动换端的成功。
