Study on transmitting signal of sensor for a long distance

在很多情况下 ,测控系统距离传感器现场较远 ,传感器信号需要远距离传输 .本文从应用的角度 ,研究了传感器信号远距离传输时 ,信号形式的选择与信号形式的转换方法 ,传输线引起的信号畸变与抑制技术 。

In many occasions,the sensors are far from the measuring and controlling systems,and the signals of sensors are transmitted through a long wire.For the purpose of practical use,the choice and the conversion of signal forms are discussed for transmitting the signals of sensors for a long distance,the distortions caused by a long transmission wire and relevant suppressing techniques are studied,and the method of regulating voltage for a long distance is presented in this paper.
