Research on theory scheme in intelligent control system of feed processing

Based on PLC, this paper blends the automatic control theory with the feed processing industry and carries out design and research on the feed production automatic control system. Mainly employing the method of combining the upper computer with the PLC, this system can collect, recognize and control data to progressively implement the automatic control of feed production process. VC and configuration software are generally used to program for the system of which the database adopts SQL Server2000 and the PLC resorts to ladder diagrams to design software programming. The running result shows that this system can detect and control safety parameters and achieve the automatic technology transform of feed production lines.
