印刷机自动化控制系统电磁干扰的抑制方法OA

The automatic control system of the printing press takes the industrial computer as the core,and controls the working state of printing machinery through precise control of motor operation.It has the functions of constant tension and automatic color matching,and is a complex automatic system.Since the system operates in an environment where high-voltage and low-voltage power coexist,minimizing Electromagnetic Interference(EMI)impact on the control system and ensuring stable operation are of paramount importance.This paper proposes specific EMI reduction methods from six aspects of control cabinet layout,wiring,grounding,shielding,filtering,and isolation.These methods have been applied in practical engineering projects,achieving remarkable results.
