[Abstract]:The anti-slip braking system of SAB train is applied to the train of T type in our country. Due to mechanical vibration, environmental corrosion and aging of the device, the anti-skid brake system of the train will inevitably bring about the malfunction because of the mechanical vibration, the environment corrosion, the aging of the device and so on. In order to check the fault state of train anti-skid braking system and improve the efficiency of fault detection and maintenance of train anti-skid main engine, this paper aims at the main engine of SWKAS20C anti-skid device of SAB WABCO Company. An expert system for component level fault detection and location is designed. Through the research of analog electronic circuit fault diagnosis technology, a multi-fault classifier based on support vector machine is designed, which can be used to train and test the fault sample data of host analog circuit. The accuracy of fault diagnosis is improved by improving the algorithm to optimize the parameters of the vector machine. A test platform is built to simulate the train running environment, which is used to simulate the fault mode of the main engine in various states. The MFC expert system is programmed by using VS2010 development environment. The application of the expert system to the fault host shows that the expert system can extract the fault accurately and efficiently, locate the fault and give the expert solution.
