摘　　要：为了解决在山地果园使用有线机械限位开关易损坏的问题和改善牵引式货运车现场作业的方便性,研制了一种山地果园牵引式货运车的无线限位及遥控装置.该系统主要包括霍尔传感器模块、按键及编码模块、AVR微控制器、CC1020无线收发单元、PLC控制单元.果园试验表明,牵引式货运车的无线遥控实现在距离接收机370 m范围内100％控制可靠,牵引式货运车限位装置在上、下限位处工作100％可靠,在距离近地点45～95 m处CC1020射频信号传播路径损耗的平均值为32.8 dBm,比PT2262射频信号传播路径损耗的平均值减少了20.8 dBm.Aiming at overcoming the vulnerability of wired mechanical limit switch and improving the convenience of the field traction cargo vehicle working in the mountain orchard, a wireless remote control and wireless limit switch device of mountain orchard traction cargo vehicle was designed. The system was mainly composed of hall sensor module, key and code module, AVR single-chip microcontrollers, CC1020 wireless transmitting and receiving unit, PLC control unit. The system verification test of orchard showed that within 370 meters from the receiver, the wireless controlling system was 100% reliable, and the limit switch system was 100% reliable, within 45 to 95 meters to the receive1, the average path-loss of radio frequency signal of CC1020 was 32.8 dBm,which was 20.8 dBm less than the path-loss of PT2262.
