Design of Low Power Consumption Wetland Environment Monitoring System Based on Lora Network

In view of the problems of large wetland environmental monitoring area, complex environment and long communication distance, a wetland environmental monitoring system based on LoRa networking communication is studied and designed in this paper. The system is composed of environmental information collection node, gateway node, cloud server and client. The environmental information collection node sends data to the gateway node through LoRa communication technology, and the gateway node sends the data to the cloud server through the 5G module after data processing to realize the remote monitoring and management of wetland environment. In order to solve the problem of packet loss rate in traditional LoRa networking, a LoRa communication mode based on CSMA/CA enhancement is proposed. The experimental results show that the functions of the system are relatively stable, the LoRa wireless effective communication distance between the environmental collection node and the gateway node is about 25500m, the node power consumption is low, and the mobile power supply can be used to meet the long-term monitoring needs, providing a technical basis and reference for large-scale wetland environmental monitoring and management.
