Design And Implementation Of Agricultural Environment Monitoring Platform Based On LoRa Technology

As the primary industry of our country,the traditional mode of agricultural production has been unable to meet the needs of the development of modern society.With the extensive application of IOT technology,the development of modern agriculture using IOT technology is a requirement of the development of the times and also a trend of agricultural development.The monitoring of agricultural environment is an important link in the development of modern agriculture.In order to solve the problem of large amount of data collection,data remote wireless transmission and visual display of data in agricultural environment monitoring,this paper is based on LoRa wireless transmission technology,using IOT technology perception layer,the sensor layer and the application layer of the three-tier architecture to design the agricultural environment monitoring platform.The main research contents are as follows.1)Environmental monitor design: Through the analysis of the agricultural environment in our country and the environmental factors that mainly affect the crops,various types of sensors can be used to realize the automatic acquisition of agricultural environment data.By the LoRa terminal module achieve remote data transmission and long-term unmanned omission in a variety of environments to long-term stable operation.2)Data wireless communication design: Data protocol is design to facilitate the transmission and storage of various types of data.According to the data collection situation,a data transmission mode of multiple monitoring points of a gateway is designed,which facilitates the deployment of monitoring points and saves the cost.The paper adopts LoRa gateway to realize the long-range,low-power wireless transmission of various types of environmental data.3)Software design: the part mainly includes the server and client design.In order to facilitate long-distance and multi-end access to various types of data,provide the data foundation for the environment monitoring platform,the server builds the server and adopts MySQL as the database management system to realize the storage and management of various types of environment data.The software adopts the SOA architecture to realize the sharing of the development structure and utilizes the ECharts visualization tool to realize the visual display of the data.Through the analysis of the data,combing with the optimum crop growth environment conditions,the mask can provide the abnormal datawarning.Finally the system can achieve the control of agricultural facilities by the issuance of control instructions.The test results show that the platform runs stably,the hardware data acquisition device works steadily.The environmental monitor has low power consumption,high wireless transmission efficiency and normal data reception.Base on the effectively improves the economic benefits of agricultural production and social benefits,it will have a good application prospects.At the same time,the research is summarized.And the idea of improving the platform design is put forward according to the needs of the actual agriculture so as to provide reference for further research in the future.
