摘要
介绍了一种新的精确农业变量施肥控制系统。该系统接收施肥和速度传感器输入信号,经过ARM嵌入式内核处理后,输出控制步进电机的脉冲信号,控制施肥机上排肥轴的转速,实现精确农业变量施肥。实践证明,该控制系统工作稳定,达到了精确农业变量施肥的要求。
A new kind of control system for the variable rate fertilizer applicator in precision agriculture is introduced. This system receives signals of fertilization rate and speed sensor dealed with the embedded micro processor of ARM, it outputs pulse signal which controls the rotational velocity of the stepping motor, then the system could control the rotational velocity of the fertilizer shaft and work automatically. Results showed that the system simple, cheap and worked stable.
