Industrial production process. A variety of instruments and meters are used in the monitoring and control of the generation process, and a variety of signals will occur: there are small signals of faint millivolt levels, large signals of tens of volts, and even Strong signals up to thousands of volts and hundreds of amperes; both DC low-frequency signals and high-frequency or pulse spike signals; and these signals must be transmitted to each other in the industrial production process. A variety of instruments and meters are used in the monitoring and control of the generation process, and a variety of signals will occur: there are small signals of faint millivolt levels, large signals of tens of volts, and even Strong signals up to thousands of volts and hundreds of amperes; there are both DC low-frequency signals and high-frequency or pulse spike signals; and these signals have to go through the process of mutual transmission and transmission, so how to ensure that these signals, especially analog signals, No distortion during transmission will become a problem that must be solved in system debugging. Only when the analog signal transmission between the control device and the sensors and actuators distributed in the field is fault-free and undistorted, specifically. Ability to ensure safe and reliable process control. In particular, low-power analog signals are affected by various external interference signals when they are transmitted in an industrial environment with high interference, and a reliable transmission channel is required. Daily work experience indicates that due to equipment requirements, it is necessary to handle and transmit analog signals carefully. However, the measurement and control parameters transmitted in the form of analog signals between the field and the control layer are often in a harsh industrial environment in the transmission project, which is likely to cause the distortion of these signals.
