The invention relates to a self-checking control system for a digital brake valve. The self-checking control system comprises a control circuit, a power driving circuit, a monitoring circuit and a current sensor, the control circuit is connected with the power drive circuit, the monitoring circuit is arranged between the power drive circuit and the digital brake valve, the input end of the monitoring circuit is connected with the output end of the power drive circuit, and the current sensor is connected with the power drive circuit and the control circuit. The current sensor is used for collecting bus current of the power driving circuit; the monitoring circuit is used for collecting level signal information output by the output end of the power driving circuit when the digital brake valve is in the first working state; the control circuit is used for determining whether the digital brake valve breaks down or not based on the level signal information collected by the monitoring circuit; and under the condition that the fault occurs, the fault type of the digital brake valve is determined based on the bus current and the level signal information. According to the invention, the fault of the digital brake valve can be reliably detected.
