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.
