The electric multiple unit (EMU) has become one of the most important components in strategic transportation in China. The braking system should receive special attention from both academic and practical perspectives. Understanding the fault of EMU braking system is one of the key points before doing research on fault detection. In this paper, we give a very brief introduction of the electro-pneumatic brake control structure and the network topology of EMU fault detection and diagnosis(FDD) module. Finally, a PCA based fault detection algorithm is proposed and the efficiency of the algorithm is verified through the experiment operated on a certain model of EMU braking system.
