Abstract: Aiming at the problems of poor visualization effect and single functional interaction mode of the digital management system for hydraulic metal structure safety monitoring, this paper designs a virtual system for hydraulic metal structure safety monitoring based on virtual reality technology. The system through the remote data access, the real-time acquisition of radial gate, the hydraulic hoister such as sensor data, through the RabbitMQ message queue associated with the virtual scene, complete the data driven by real-time simulation, and monitoring the chart data visualization, which realizes the spillway hydraulic metal structure safety monitoring and the integration of virtual reality technology. And the system is applied to the actual hydraulic metal structure safety monitoring through virtual roaming, model interaction and dynamic simulation. The application shows that the system has advantages like strong immersion and good interactivity, and can monitor the operation status of gates and hydraulic openers in real time, which helps managers to make accurate judgments on the safety operation and maintenance of hydraulic metal structures at the later stage. It serves as a valuable reference for the intelligence management of hydraulic metal structures.
