Abstract
With the vigorous development of urban rail transit industry in recent years, the quantity and quality requirements for subway vehicles are higher. The existing electric control system of subway vehicles is controlled by the contact scheme represented by relay, which has many shortcomings such as high cost, high failure rate, and no redundancy in logic cascade. If the single point and relay fault in the control circuit, the subway vehicles cannot operate, and the problems of vehicle cleaning and rescue will occur. This paper introduces a design scheme of the standby mode of subway vehicle control circuit. The programmable Logic Control Unit (LCU) is used to design bypass, which can affect the key control circuit of the train, so that the subway can continue to run to the station in the fault state, avoid the congestion of the line, and solve the problem of vehicle clearing and rescue caused by the fault.
