IMP在电厂监控系统中的应用

对于电厂数据采集环境比较复杂、信号分散的情况，可采用隔离测量组件（ＩＭＰ）作为分散式数据采集的前瑞，直接安装在传感器或变送器的附近。其具有防磁、防尘、防水、防震等性能。ＩＭＰ还可以对采集的数据就地进行数字化加工及一些预处理，通过Ｓ－网络进行数字量的传输到主计算机。避免了由于信号电平较低，传输距离及较远时带来的信号衰减及噪声干扰。

IMP Application in Power Plant Monitoring and Control

In power plants, the environment for data acquisition is usually complex andsignals are decentralized.Isolated Measurement Pods (IMP), in this case, can be used as thehead of decentralized data acquisition, and installed near sensors or transducers. IMP isdurstproof, shockproof, waterproof and antimagnetic. By use of it, the data acquired can bedigitized, pre-processed locally, and transmitted to the main computer through S-network.The signal decaying and noise due to low signal level and long distance tramsfer can thus beeliminated.
