Three-dimensional digital deduction method for top cover maintenance hoisting operation and risk identification

The invention relates to a three-dimensional digital deduction method for top cover maintenance hoisting operation and risk identification. The method comprises the steps: constructing a top cover three-dimensional refined model and a top cover maintenance operation virtual scene; establishing an early warning rule based on space collision early warning; designing a top cover hoisting path planning method meeting an early warning rule, and determining an optimal top cover hoisting path, so a worker has a vivid feeling and an immersion feeling during operation, and seamless fusion of a model, atool and an overhaul scene in a top cover overhaul process is realized; deducing the field operation scheme, completing collision analysis and optimal path planning, and realizing safe deduction of the top cover maintenance operation. 本发明涉及一种顶盖检修吊装作业与风险辨识三维数字化推演方法，包括：构建顶盖三维精细化模型及顶盖检修作业虚拟场景；建立基于空间碰撞预警的预警规则；设计满足预警规则的顶盖吊装路径规划方法，确定最优的顶盖吊装路径；让工作人员在操作时具有逼真感和沉浸感，实现顶盖检修过程中模型、工器具与检修场景无缝融合；对现场作业方案进行推演，完成碰撞分析以及最优路径规划，实现顶盖检修作业安全推演。
