The invention discloses a locomotive parking and braking state detection system which comprises a system main air channel, a brake cylinder air channel, a parking control air channel, a two-way valve, a switching valve, a double-linkage cock, a first pressure switch and a second pressure switch, the switching valve is arranged on the main air channel, a control port of the switching valve is connected with the two-way valve, and an inlet of the switching valve is connected with a main air pipe; an exhaust port of the switching valve is communicated with the atmosphere, a first air inlet of the double-linkage cock is communicated with the two-way valve, a first air outlet of the double-linkage cock is communicated with a brake pipeline of the parking cylinder pipe, and the first pressure switch is arranged on the brake pipeline of the parking cylinder pipe and the first air outlet of the double-linkage cock. A second air inlet of the double-linkage cock is communicated with a main blast pipe through a switching valve, a second air outlet of the double-linkage cock is communicated with a second pressure switch, the invention further discloses a method corresponding to the system, the real state of the parking brake is visually detected through feedback signals of the first pressure switch, the second pressure switch and a switch display device, and the real state of the parking brake is displayed. The pressure of the parking cylinder is distinguished from the brake cylinder or the parking control tube.

    本发明公开了机车停放制动状态检测系统,系统总风气路、制动缸气路和停放控制气路、及双向阀、切换阀、双联动塞门、第一与第二压力开关,切换阀设于总风气路上,切换阀的控制口连接双向阀,切换阀的进口连接总风管,切换阀的排气口连通大气,双联动塞门的第一进气口连通双向阀,双联动塞门的第一出气口连通停放缸管的制动管路,第一压力开关设在停放缸管与双联动塞门的第一出气口的制动管路上,双联动塞门的第二进气口通过切换阀连通总风管,双联动塞门的第二出气口连通第二压力开关,还公开了与系统对应的方法,通过第一压力开关、第二压力开关和开关显示装置的反馈信号直观的检测停放制动的真实状态,区分停放缸的压力是来自制动缸或停放控制管。
