Real-time Monitoring And Early Warning System Of Remote Environment Based On LoRaWAN And Android

China is a big agricultural country.China supports one-fifth of the world's population with 7% of the world's cultivated land.China's traditional agriculture has many problems,Therefore,there is an urgent need for high-tech modern agricultural technology to promote the rapid development of agriculture.In recent years,Internet of Things technology,computer technology and network transmission technology have been rapidly developed.The real-time monitoring of agricultural Internet of Things with these technologies as the core has emerged.The agricultural real-time intelligent real-time monitoring system realized by advanced Internet of Things technology,wireless network transmission and computer technology realizes real-time monitoring of high-efficiency remote environment.With the popularity of smart mobile terminals,mobile development will become the mainstream trend of development in recent years.Android-based mobile terminals occupy one-third of the market due to their openness and open source,and may continue to grow in the future.Then Android-based mobile development will have considerable prospects and value in the future.Based on the above background,this paper designs a set of fully functional remote environment real-time monitoring and early warning system based on LoRaWAN and Android.The system implementation level mainly includes data acquisition module based on LoRaWAN wireless sensor network,server module containing database,Android side and related middleware development and design and implementation.In the data acquisition module,design and implement wireless sensor selection,wireless sensor installation and configuration,reading and parsing of wireless sensor signals and transmission of signal data,LoRaWAN network platform construction and configuration deployment and information communication with the server.On theserver side,the design and implementation of the server and database configuration,design and implementation of the server to obtain the data acquisition module wireless sensor data information and data communication with the Android side.On the Android side,design and implement data communication between the Android side and the server side,and complete the interactive function development between the Android side and the user.After completing the relevant development,we test the system from the unit test and the overall test.The test results show that the system unit functions normally,the overall operation is normal,and achieved the desired goal.
