摘要
针对秦岭-淮河以南的丘陵地区控制信号传输距离远且环境恶劣、灌溉用水效率低下等问题,设计了基于LoRa技术的智能灌溉系统,该系统终端节点传感器通过Modbus协议传输在稻田采集的参数,考虑未来降水因素,采用了风险灌溉策略。实验结果表明,所设计的灌溉系统准确率高、智能高效,可以精准灌溉作业。
Aiming at the hilly area south of the Qinling-Huaihe River,which has long control signal transmission distance and harsh conditions,and low efficiency in irrigation water,design the intelligent irrigation system based on the technology of LoRa.The system terminal node sensor uses the Modbus protocol to transmit the parameters collected in paddy field.Considering the future precipitation factor,risk irrigation strategy is adopted.The experimental results show that the designed irrigation system has high accuracy,is intelligent and efficient,and can perform precise irrigation operations.
