Design of Electromagnetic Compatibility in automatically-controlled Door Control System used in EMU

Abstract

In order to improve anti-interfere ability and increasing stability and reliability of automatically-controlled door Control System used in high speed Train. In this paper, we analysis the reason of electromagnetic interference and electromagnetic radiation on the system. the restrained technology of t he hardware interference was studied from the ranges of circuit board design , GND design , insulated technology and power interference rest rained aspects , and the software anti-interference mechanism was al so studied from redundancy. Based on this , the design of electromagnetic compatibility in automatically-controlled door Control System used in high speed Train was accomplished.Through actual vehicle experiments , the system design was verified , and the result showed that the system design is accuracy , reliable and creditable.
