Electromagnetic compatibility design of automatically-controlled door control system used in high speed train

In order to improve the anti-electromagnetic interference ability and to enhance the stability and reliability of automatically-controlled door control system used in high speed train. The performance of electromagnetic interference and electromagnetic radiation were analyzed in this paper, the restrained technology of the hardware interference was studied from the design of printed circuit board, ground design, insulated technology and power interference suppression, and the anti-electromagnetic interference mechanism of software is studied from redundant technology. Based on this, the electromagnetic compatibility design of automatically-controlled door control system used in high speed train was accomplished. Through actual train experiments, the system design was verified, and the result showed that the system design is accuracy, reliable and creditable.
