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...
