Automatic control system of liquid pesticide ingredients production line

摘要

Chemical pesticides security and configuration problems of low precision blending process design a kind of liquid chemical pesticide ingredient line automatic control system. System consists of Host-Computer, PLC, weighing instruments and touch-screen configuration, which use Visual Basic develop design software, with data collection, storage and query capabilities. Omron PLC as the master controller for receiving the weighing instrument collection data and by controlling the electromagnetic valves and mixers and other equipment precise to control pesticide materials intake exactly. Using FINS protocol for communication between Host-Computer and PLC real-time data exchange. Commissioning of system has been successfully applied to a liquid chemical pesticide production plant. System has the safety, accurate and efficient advantages, and low construction cost, simple structure, has great marketing value.
