Design of Automatic Control System for Intelligent Micro Drip Irrigation Based on PLC Technology

Abstract:

This paper analyzes the control requirements of drip irrigation system, designed automatic drip irrigation control system with IPC and PLC as control core, using WinCC as the man-machine communication window, combined with frequency, field bus and sensor technology. This paper focuses on the system hardware design, system control software and system monitoring software design. Through the field bus, the central management computer decide reasonable irrigation decision according to the soil moisture information, crop water requirement characteristics and predetermined irrigation scheme, and then issued a directive to the solenoid valve scattered, automatic carry out proper, required precision irrigation control. The practical application shows that: the system has stable working performance, friendly interface, improve labor productivity. The system can be expanded easily in terms of structure and function, can satisfy the application of different scale, demand, cost, have certain application prospect.
