| 英文摘要: |
| 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 receiver, the average path-loss of radio frequency
signal of CC1020 was 32.8 dBm袁which was 20.8 dBm less than the path-loss of PT2262. |
