Design of Feed Production Line Control System based on PLC and Ethernet
In our country,the straw mechanization processing level is low,using cost is high,which causes a serious waste of straw resources.In order to realize fully automated feed production and improve production efficiency,a feed production line control system based on Siemens S7-200 SMART PLC and Ethernet communication is designed.This paper focuses on the process design of wrapping production line,hardware system selection,control circuit design,software system I/O point allo-cation and control process design,and realizes the automatic ratio of straw raw materials,mixing and stirring,wrapping stor-age,field monitoring,fault alarm and other functions.The test results show that the production line can control the whole process of batching and production through the industrial computer or touch screen,which has a high degree of intellectualiza-tion and automation;and it is suitable for the feed production industry to meet the growing needs of feed consumption in do-mestic animal husbandry.
