【Background and Objective】In order to overcome the difficulty about laying electric wires in the field and realize unmanned filed irrigation, improving the intellectualization and precision of irrigation in rice planting area in Anhui Province and exploring the feasibility of intelligent control of irrigation sluice by using new generation electronic information technology would be carried out in the research.【Method】An intelligent irrigation control system based on AT89S52 single chip computer was designed in this paper, which included integrated lifting sluice, irrigation hardware subsystem and irrigation software subsystem. The gate of the sluice was adopted integrated design, which was integrated central processing unit module, sensor sensing module and solar power supply module based on AT89S52 MCU. Keil C developed the control software for the terminal of the gate, and the upper computer control software of the system was developed by C++. 【Result】The application test showed that the automatic control response time of the motor was less than 1 s, the gate of the sluice opening control error was less than 1.5 mm, the water level control error was less than 8 mm, the maximum packet loss rate of data transmission was 0.11%, the calculation error of free discharge flow was less than 1%, and that of submerged outflow flow was less than 1.2%.【Conclusion】This system run safely and stably, and could meet the requirement of intelligent and precise water use in the complex environment of field irrigation of rice planting area.
