Design and application of intelligent controller for precise irrigation in rain-avoiding cultivation.

Aiming at the characteristics of wide irrigation area,huge amount of data,and difficult real-time transmission of data in cropland irrigation control,the author designed a intelligent controller for the precise irrigation in the rain-avoiding cultivation.This controller adopted multiple-time and multi-combination intelligent control with double-mode(manual and automatic operation) safety insurance.Many environmental factor parameters in the growth environment of crop could be transmitted to the main engine by wireless transmitter,and then the running of the water pump could be controlled by the terminal.Based on the advantages of Zigbee mode,such as agile disposal,convenient extension and so on,this system could realize the acquisition,transmission and receiving of signals in crop growth environment,such as carbon dioxide,illumination intensity,air temperature,air humidity,and soil moisture content.
