The groundwater monitoring system is an important means to grasp the laws of groundwater changes, understand the status of groundwater exploitation, and guide the protection of groundwater resources. The groundwater monitoring system can conduct long-term monitoring of parameters such as water level, temperature, and quality of groundwater, and automatically store monitoring data. It can dynamically analyze the changing patterns of groundwater. The system construction objectives are as follows:
1) Implement regular collection of groundwater level, water temperature, and water quality information, as well as early warning notifications, to ensure the efficiency, timeliness, accuracy, and adequacy of system information.
2) All data is transmitted directly to the monitoring center via wireless network; Groundwater Monitoring System; Visually display data information and alert status of each measurement point in the electronic map visualization interface; When an alarm occurs, the system can automatically send out an alarm signal, such as popping up a message or emitting a sound prompt.
3) System development should adhere to the principles of advanced practicality, stability, and reliability, and have good scalability, compatibility, and openness, providing standardized interfaces for later system expansion and upgrading, and providing data sharing services to other related platform systems.
The groundwater monitoring system relies on the existing 4G/5G wireless network for construction, which has the advantages of low investment cost, fast construction speed, and no communication distance restrictions. The system supports the groundwater communication protocol of the Ministry of Water Resources and has been widely used in national groundwater monitoring projects in various regions.
Overall scheme design
The construction of a remote monitoring system for groundwater includes the collection equipment for on-site water level, water temperature, and water quality information, as well as the construction of a monitoring center information reception and display and application system. The collection and transmission equipment for on-site monitoring data completes the scheduled collection, basic analysis and processing (such as alert status), and display of water level, water temperature, and water quality information. It is also responsible for transmitting the data wirelessly to the monitoring center via 4G/5G, receiving, displaying, storing, analyzing, processing, and warning the data through software.
