Implementation of Precise Drip Fertilization's Monitor System
Hongwei Li · Journal of Shihezi University · 2011
In order to improve the automation level of drip fertilization process,master manufacturing process information real time,execute precise operations,a IPC and PLC-oriented monitor system for precise drip fertilization was designed and realized.The system setup fertilization parameter that matched nutrient demand of crop different growth stage by human-machine interface,IPC detect parameter of control object by PLC and real-time display,PLC obtain control signal by PID algorithm and impact actuator,automaticaly regulate controlled variable,system can realize precise monitor of drip fertilization process.
