Research And Implementation Of Agricultural Environment Monitoring System Based On CoAP Protocol

In recent years,with the country’s comprehensive implementation of the rural revitalization strategy,the importance of agricultural development has become increasingly prominent.In order to carry out digital rural construction and connect with the rural revitalization strategy,China is vigorously promoting smart agriculture and developing agricultural productive service industries that use data as a key element.The current agricultural environmental monitoring system lacks a unified standard,and has problems such as short communication distance,high investment cost,difficult deployment,and low security.Therefore,the development of an intelligent agricultural environment monitoring system has very important application value.According to the management needs of greenhouses and the growth environment of crops,this paper researched and implemented the agricultural environmental monitoring system based on the CoAP protocol.The system composed ofracquisition terminal,CoAP server,environmental monitoring platform and WeChat Mini Program.The acquisition terminal uses STM32L431RCT6 as the main control chip,and sends the information collected by the sensor to the CoAP server through the SIM7020C module.The CoAP server is designed and developed based on the Node-CoAP framework to realize the analysis and storage of data,The environmental monitoring platform is designed with B/S architecture and developed based on the Spring Boot and Vue frameworks,The mobile WeChat Mini Program is developed with the MINA framework,which realizes the display of environmental parameters,equipment management and remote configuration.At the same time,Based on the LSTM neural network for the environmental changes in the greenhouse,the agricultural environment prediction model is established to realize the prediction of agricultural environment.Finally,various functions of the environmental monitoring system are tested,including NB-IoT network access test,CoAP server receiving data test,environmental monitoring platform and WeChat Mini program test.The test results show that the agricultural environmental monitoring system meets the expected goals and has high practical value for the development of smart agriculture.
