基于LabVIEW监控系统的传感器信号干扰分析及解决方案

Analyzing and Processing Polluted Signals Based on Labview Monitor System

利用LabVIEW软件对采集回来的数据进行处理分析,得出了变频器及工厂特殊环境对监控系统信号所造成的干扰分析,最后通过单独提供稳压电源及信号滤波处理等方法解决了采集信号不稳定性的问题,从而保证了监控系统的有效正常运行.

The data based on the labview monitor system are analyzed,The conclusion that the monitor signals are polluted by the frequency conversion and the electric environment of factory is obtained. A voltage stabilizer for each electric circuit and signals filter are given. Finally, the problem is solved by this method,which assures the proper working of the monitor system.
