Anti-Electromagnetic Interference Design for Railway Vehicles in Complex Electromagnetic Environment
With the increasing applications of information and communication technology in rail transit systems, the electronic and electrical devices in railway vehicles causes the serious electromagnetic interference (EMI) problem among any subsystems and devices. In this paper, an anti-EMI design scheme for railway vehicles is proposed, which can improve the anti-EMI ability of whole railway vehicles in terms of shielding, grounding, filtering and wiring. Based on Shanghai Metro Lines 4 and 6, the system implementation and testing are performed. The test results show that the proposed scheme can be effective and efficient to resolve the electromagnetic compatibility (EMC) problem.
