Irrigator Automatic Operation Control System

In order to further improve efficiency of agricultural irrigation water，a kind of automatic irrigator control system was designed，which obtained prescription figures from server through GPRS communication，and compensated them with pressure data of irrigation water sent back in real time through ZigBee wireless transmission module.Working frequency of inverter，which decided the sprinkler’s walking speed，could be adjusted with GPS coordinates information in the current position.And then，sprinkler would work according to prescription figures.It also had manual function，such as control of sprinkler’s walking motor and adjustment of inverter’s working frequency.
