1. Background of the program
In recent years, geological disasters caused by the long-term influence of groundwater have appeared frequently. Falling funnels, ground subsidence, ground fissures, karst collapse, seawater intrusion, and water pollution have caused panic and reminded people of the comprehensiveness and accuracy of groundwater monitoring. There is still a lot of room for improvement. Groundwater monitoring has been developed to a certain extent with economic and social development, but with global climate change and continuous changes in water resources conditions, groundwater monitoring has encountered many new situations and new demands. On the basis of basically mastering the occurrence and distribution characteristics of groundwater, establish a long-term monitoring network for groundwater, improve automatic monitoring capabilities, strengthen information services, carry out research on basic theories and applied technologies, improve scientific protection and rational utilization of groundwater resources, and realize the use of water resources. It is very necessary to support the sustainable development of society and economy through sustainable utilization.
2. System overview
The groundwater monitoring system uses the Internet of Things technology, combined with the 5G/4G/3G wireless network, NB-IoT network and other networks of major operators, to monitor the pH, temperature, total hardness, sulfate, nitrite, iodide, benzene and other properties of groundwater. , chloride, lead, Escherichia coli, total bacteria and other key data are collected in real time, and the data is transmitted in real time through the water conservancy telemetry terminal, so that the backend can remotely obtain groundwater data and monitor the groundwater level to prevent overexploitation. Real-time monitoring of the underground environment is also carried out to comprehensively ensure that groundwater exploitation is compliant and reasonable, and groundwater safety is ensured.
3. System composition
The groundwater monitoring system consists of three parts: data acquisition part, network transmission part, and data management center.
Data acquisition part: The data acquisition part is composed of water level sensor, water temperature sensor, PH sensor, conductivity sensor, turbidity sensor and other groundwater monitoring sensors to collect data on groundwater quality;
Network transmission part: The main equipment of the network transmission part is the intelligent telemetry terminal, which is responsible for connecting the front-end acquisition equipment, and transmits the data collected by the front-end acquisition equipment through the 5G/4G/3G wireless network or other networks such as NB-IoT and WiFi;
Data management center: The data management center can be divided into three small parts, namely, the water resources monitoring cloud platform, data processing center, and database storage. The water resources monitoring cloud platform can use the water resources monitoring cloud platform or the user-developed one The water resources monitoring cloud platform displays and processes the graphical data through the large screen, PC terminal, and mobile terminal, and stores the data in the database for permanent storage of the data.
