非织造布水刺生产线中变频设备干扰的消除

Anti-disturbance of transducer on nonwoven spun-laced production line

非织造布梳理成网及水处理自动控制中,变频器的电源反馈和电磁感应对自动控制系统中的采集信号、控制信号等弱电信号都会产生较大的干扰,使其无法正常工作。通过软件滤波、数字信号处理以及硬件上的电容滤波、屏蔽和接地等能较好地去除干扰,替代昂贵的进口变频器电源抗干扰器。

In automatic control system of disturb the sample signals and quency noise, this disturbance nonwoven carded web and water-treatment equipments. The transducer will control signals. By computer digital filter and capacitor reducing high frecan be largely reduced.
