Research On Low Power Consumption Water Pollution Monitoring System Based On NB-IoT Technology

With the rapid development of industrialization,industrial sewage is discharged randomly,and water pollution related events occur frequently Water pollution not only affects the ecological environment,but also reduces the quality of people’s drinking water.Human physical and mental health is also facing great challenges.Therefore,how to make rational use of and protect water resources and how to prevent water pollution at the source are major problems that need to be solved urgently.China’s water pollution monitoring has experienced a long development,from manual data collection and analysis to the unpopular water pollution monitoring system.Although the monitoring of water pollution monitoring system reduces manpower compared with manual data collection and analysis,and is more convenient and fast,the monitoring cycle is long,and the price of the whole set of monitoring equipment is very expensive,so it is not suitable for long-distance monitoring and popularization.For the above environmental problems,a low-power water pollution monitoring system based on Nb IoT technology is designed.NB IoT technology is a long-distance,low-power wireless communication technology.This technology solves the problems of high cost and node energy consumption.The research contents of the system Ⅰ studied are as follows:1.The system architecture of water pollution monitoring is constructed.The system is mainly divided into six modules:power supply module,embedded control module,sensor monitoring module,NB-IoT module,cloud platform and host computer module.The data is monitored through the sensor monitoring module,the data is processed through the embedded control module,and the processed data is uploaded to the cloud platform through the NB-IoT module and displayed on the host computer,which constitutes a complete water pollution monitoring system.2.The hardware and software of the water pollution monitoring center of the whole system are designe.Based on the design of the main controller,other modules of the system are designed step by step,including the peripheral circuit module,power module,NB-IoT communication module,sensor module and so on.At the same time,the low-power and stable program design of the system is also carried out to ensure the efficient and stable operation of the system.At the same time,the cloud platform is built,the upper computer monitoring center is built,and the human-computer interaction is realized Make it easier for users to view water pollution information.3.The software and hardware of the system module are designed.The communication module is tested,and the performance and accuracy of the sensor terminal module are also tested.The test results also show that the measurement accuracy of the monitoring module in this study meets the design requirements.Therefore,the water quality monitoring system in this study can meet the research standards.Therefore the designed system can be applied to the field of water quality monitoring.Figure[50]table[10]Reference[62]...
