Design Of Water Quality Monitoring System Based On LoRa

With the growth of the world's population,the level of industrial production and agricultural production has increased substantially,resulting in a substantial increase in water consumption.At the same time,due to the daily production and life of human beings,the water quality of surface and groundwater bodies has deteriorated,Water consumption and pollution have caused water resources to become scarcer.In the case of increasingly scarce water resources,cherishing water resources,monitoring water quality during use,and ensuring people's peace of mind when using water,the use of peace of mind becomes more important.Traditional water quality monitoring technology requires manual water withdrawal and back to the laboratory for analysis.It consumes a lot of manpower and material resources and cannot meet the requirements of large-scale,all-day real-time monitoring.With the rise of low-power WAN technology,its low power consumption and long-distance characteristics are required in the field of water quality monitoring.Water quality monitoring data is transmitted to the control platform through LoRa technology,and users of the platform can change according to the real-time on the webpage.The water quality monitoring data makes corresponding decisions.First of all,this paper analyzes the development stage of water quality monitoring and the development of LoRa technology at home and abroad.Considering the bottlenecks in the field of water quality monitoring and the characteristics of LoRa technology,the feasibility of applying LoRa technology to the water quality monitoring system in water quality monitoring is studied.First of all,this paper analyzes the development stage of water quality monitoring and the development of LoRa technology at home and abroad.Considering the bottlenecks in the field of water quality monitoring and the characteristics of LoRa technology,the feasibility of applying LoRa technology to the water quality monitoring system in water quality monitoring is studied.Then,the data acquisition module and gateway module of the water quality monitoring system are designed in detail,the water quality monitoring parameters are analyzed and the sensor and development board are selected,the BeiDou module is added,the geographical location information of the acquisition module is obtained,and finally the code corresponding to the LoRaWAN protocol is written.Recorded into the development board.The gateway module is mainly responsible for collecting the information uploaded by the acquisition module and sending it to the LoRa server.It also needs to complete the hardware selection and software design.Finally,the deployment of the LoRa server is completed,and then the LoRa system is built.Finally,the paper gives a detailed design of the LoRa-based water quality monitoring system.The system adopts JavaWeb,based on the mainstream framework integration of Struts + Spring + Hibernate,combined with JSP and CSS for development and design,completes the acquisition and classification display of sensor data,and the water quality monitoring system mainly includes functions such as rights management function,real-time map display function and historical data viewing function.
