Embodiment 1
[0063] Embodiment 1 of the present invention provides a dam safety early warning and fire-fighting method based on digital twins, which establishes a digital twin dam for a real physical dam, and reflects the safety status of the real physical dam through the digital twin dam; Real-time monitoring of dam safety status, and early warning and risk control, such as figure 1 shown, including the following steps:
[0064] Based on physical dam through adaptive numerical simulation, comprehensive evaluation model, dynamic recursive data drive, online data assimilation model, abnormal diagnosis reasoning, behavior understanding, reality and XR model, data and mechanism-driven control model construction and physical dam safety A digital twin dam with the same state, consistent influencing factors, measurable response synchronization, and realistic multi-dimensional scenes;
[0065] Through the digital twin dam, the real dam can be visualized and facilitated to perceive and diagnose a...
Embodiment 2
[0199] Based on the digital twin-based dam safety early warning and alarm elimination method in the first embodiment, the second embodiment of the present invention provides a dam safety early warning and alarm elimination system based on digital twins, such as figure 2 shown, including twin dam systems used to map physical dams in the objective world;
[0200] The physical dam is equipped with state sensing equipment and facilities and operation control equipment and facilities. The state sensing equipment and facilities include the dam body, the dam foundation, the interior and surface of the dam abutment, as well as the air, water and underwater areas around the dam. Sensors, drones, and unmanned ships for sensing various loads, boundary conditions, and dam safety response parameters related to the safe operation of dams, as well as real-time sensing of geological terrain / hydrological landforms / meteorological climate / operation management information Sound, light, and elect...

Abstract
The invention discloses a dam safety early warning police eliminating method and system based on digital twinning. The method includes the following steps that through self-adaptive numerical simulation, a comprehensive evaluation model, a dynamic recursion data driving model, an online data assimilation model, an abnormal diagnosis reasoning model, a behavior understanding model, a real scene and XR model and a data and mechanism hybrid driving control model, the safety state of the dam is the same as that of an objective physical dam, influence factors are consistent, measurable responses are equivalent, and the safety of the dam is ensured. The invention discloses a digital twin dam with multi-dimensional scene fidelity. Information perception and optimization, information abnormity diagnosis, structural safety and system working state online evaluation, dam safety state accurate forecasting, wreck consequence effective early warning, dam safety state reasonable regulation and control and subsequent measure suggestion targeted recommendation are carried out on an objective physical dam through a digital twin dam. The method is complete in system, outstanding in innovation and practicability and good in application and popularization value.
Description
technical field [0001] The invention relates to a method and system for early warning and elimination of dam safety based on digital twins, and belongs to the technical field of smart water conservancy. Background technique [0002] A digital twin is a simulation model established for a specific object in a virtual space with a specific purpose. It is neither a simple sketch, photo or image of an actual physical object or process, nor a simple collection of all-encompassing real physical objects. It is a high-fidelity model that simultaneously maps the actual physical object for a specific target and accurately characterizes one or several aspects. Models are highly consistent with real physical projects, scenarios, and processes, with easy-to-understand intuitiveness and convenient interactivity. [0003] However, at present, digital twins are mainly aimed at the manufacturing or construction process, specific project operation management, especially for the perception, ma...
