摘要
针对当前泄洪消能建筑物运行期水流特性多变、地理环境复杂、水利信息散乱、信息处理效率低下等挑战,以高坝枢纽水垫塘为典型场景,提出一种面向该场景的数字孪生仿真系统设计与实现方法。该方法以搭载虚拟摄像头的虚拟无人机巡检作为辅助手段,从建模-数据-交互-仿真模拟-设备孪生体多个维度建立虚拟空间的对应映射关系和交互环境,为高坝枢纽的安全运行提供决策依据。阐述了数字孪生技术在高坝枢纽建筑中的运用,为减少数字孪生模型响应时间,提出在数字孪生仿真系统下使用二次度量误差边折叠算法(QEM)解决网格模型复杂问题,并通过实验结果验证其建筑原型设计的完备性。为下一步的图像处理等智能化应用提供决策参考。
In response to current challenges such as variable water flow characteristics during the operation period of flood discharge and energy dissipation buildings,complex geographical environments,scattered water conservancy information,and low information processing efficiency,taking the high dam hub water cushion pond as a typical scenario,we propose a digital twin simulation system design and implementation method for this scenario.This method uses virtual drone inspection equipped with virtual cameras as an auxiliary means to establish corresponding mapping relationships and interactions in the virtual space from multiple dimensions of modeling-data-interaction-simulation-equipment twins,providing decision-making basis for the safe operation of the high dam hub.We explain the application of digital twin technology in high dam hub construction.In order to reduce the response time of the digital twin model,we propose to use the quadratic metric error edge folding algorithm(QEM)to solve the complex problems of the grid model under the digital twin simulation system.And the completeness of its architectural prototype design was verified through experimental results.Provide decision-making reference for the next step of intelligent applications such as image processing.
