Abstract
This paper completes the structure design of the feed process for the small rectification experimental unit. According to the process requirements, the overall scheme of the detection and control system and the main parameters are designed, and the type of the instrument is selected. The system hardware design is based on the CPU222 of Siemens s7-200 PLC (Programmable Logic Controller) and the corresponding input/output module. The lower computer adopts STEP 7-Micro/WIN programming software, and it completes the program design of parameter acquisition, scale transformation and PID (Proportion Integration Differentiation) operation through ladder diagram. The monitoring interface of the upper computer adopts Kingview monitoring software.
