In response to the requirements of low power consumption and reliability of wireless sensor networks for field agri-cultural data collection,this paper designed a field agricultural data collection and monitoring system based on LoRa wireless sensor networks.The sensor terminal node adopted LoRa communication technology to construct a field agriculture monito-ring network.The node collected parameters of the field crop growth environment,such as weather,soil temperature and humidity,nitrogen,phosphorus and potassium content,pH value in real time.The collected data was sent to the Internet of Things(IoT)gateway through LoRa radio frequency signals.The gateway adopted a heterogeneous network communication method composed of LoRa and 5G to complete the conversion between LoRa and 5G signals.The converted data signals were sent to the cloud server through 5G data packets,and the smart agricultural data management platform called the ap-plication program interface(PAI)of the cloud server to achieve data analysis and visualization processing.Through experi-mental examples,it was verified that the proposed system had achieved low-power collection and long-distance transmis-sion of field agricultural data,with stable network performance and high reliability.
