摘　　要：设计了一种基于ARM9+Linux的行走式节水灌溉精量施水控制系统。该系统接收各种输入信号,经过ARM嵌入式内核处理后输出控制步进电动机的脉冲信号,由步进电动机控制阀门,调节出水量,实现精量施水。室内试验结果表明,该控制系统具有一定的稳定性,能达到预期效果。A control system of precision water disperser on the walking-type irrigation was designed based on advanced RISC machine （ARM） and Linux. The various kinds input signals were received by the system and were dealt with the embedded kernel of ARM. Then it provided the pulse signals of the step motor to control the valve opening. Finally, the purpose of precision water disperser was realized in precision agriculture. The experimental results prove that the control system has certain stability and can reach the anticipated effects.
