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.
