摘　　要：电磁干扰会对信号的传输以及设备的稳定运行带来不利影响。本文对按摩椅电机控制系统的电磁干扰机理展开分析,给出了几种抑制和防护电磁干扰的措施,按摩椅电机上的干扰源主要是电机的起停、换向对按摩椅控制系统的电磁干扰,为了降低对单片机控制系统的辐射干扰,采用硬件屏蔽的措施,并且为了削弱孔缝耦合的干扰,对屏蔽机箱进行孔缝处理。对单片机控制系统的传导干扰需要采用合理布线以及滤波的方法改善这些干扰,虽然不能从根本上解决这些不同的干扰,但是可以在最大程度上削弱这些干扰。Electromagnetic interference will adversely affect the transmission of signals and the stable operation of equipment.This paper analyzes the electromagnetic interference mechanism of the massage chair motor control system,and gives several measures to restrain and protect the electromagnetic interference.The main interference source of the massage chair motor is the electromagnetic interference of the motor starting and stopping and reversing to the massage chair control system.The conduction interference of MCU control system needs to be improved by means of reasonable wiring and filtering.Although these different interferences cannot be solved fundamentally,they can be weakened to the greatest extent.
