EPBS_FIDMV: A fault injection and diagnosis methods validation benchmark for EPBS of EMU

Abstract

The electro-pneumatic brake system (EPBS) is an essential part of electric multiple units. Fault diagnosis (FD) methods play an important role in the safe operation of EPBS, and have been active research direction. The literature is considerably on studies concerned with new fault diagnosis methods, while how to quantitatively validate these methods for EPBS is quite few. The main attribute is the difficulty of obtaining fault data due to the long-term normal operation. Besides, fault experiments on the real platform are hard to control, and the cost is high. Therefore, this paper presents a new open-source benchmark for validating the FD methods of EPBS. Initially, we review the existing pure datasets and benchmarks available for validating FD methods, revealing a notable absence of a benchmark specially designed for EPBS. Then, the normal and fault models of EPBS are established and implemented by co-simulation of AMESim and MATLAB/Simulink. The fault models include brake cylinder faults, train pipe faults, EP valve faults, and sensor faults. Additionally, a GUI interface is developed to visually present the validation results. The benchmark accompanying this paper is available on the website at http://gfist.csu.edu.cn/Download.html.
