Disclosed is a redundancy device for pressure control of a brake cylinder. The redundancy device for pressure control of the brake cylinder comprises a total air filter, a pressure regulating valve, an air charging solenoid valve, a first air exhaust solenoid valve and a second air exhaust solenoid valve, and further comprises a first pressure sensor, a switching solenoid valve and a second pressure sensor, wherein the total air filter, the pressure regulating valve, the air charging solenoid valve and the first air exhaust solenoid valve are arranged in a total air inlet in sequence, the second air exhaust solenoid valve is arranged between the total air filter and the pressure regulating valve. Due to the fact that the second pressure sensor is added, a brake control unit can detect whether the first pressure sensor has a fault or not at first, the first pressure sensor is switched to the second pressure sensor under the condition that the first pressure sensor has a fault, double guarantees are achieved, and the reliability of a system is improved. In addition, the brake control unit outputs control instructions according to the states of the first pressure sensor and the second pressure sensor and the current state of a locomotive so as to control the corresponding solenoid valves to change air channels, and therefore the regulating speed is high, and the control accuracy is high.
