Abstract:In order to improve the control accuracy of the current and voltage of the copper rectifier and reduce the operator's labor intensity, a set of high-power rectifier power supplies controlled by the PID is designed, and the computer equipped with Kingview is used as the host computer. The Siemens S7-200 PLC, as the slave computer, transmits the real-time collected parameter information to the PLC and Kingview through the field sensor. The PLC and the corresponding module drive the execution mechanism to complete the corresponding actions and realize the system automatic monitoring.
