Construction of Groundwater Monitoring and Intelligent Management and Control System Based on Internet of Things and Digital Twin Technology

图片
(1)  This project uses the Internet of Things, digital twins and numerical simulation technologies to build an automatic control and integrated display service system, construct an underground three-dimensional data base, and realize automatic monitoring of continuous changes in groundwater levels and water quality through a data acquisition platform. The automatic control system and mobile management APP are used to realize remote control of control cabinets and intelligent valves for recharge and backflow operations. The main construction tasks are as follows: (1) Construct an underground three-dimensional data base. According to the project construction requirements, the underground three-dimensional data base is constructed through digital twin technology, and the recharge wells and key equipment and facilities are finely modeled. The dynamic changes of groundwater levels are simulated using numerical simulation technology. (2) Build an automatic control and integrated display ...
