| 摘 要： | 为保证起重作业的安全高效性,减少起重作业空间冲突的风险,设计起重作业Manhattan平面,剖析起重作业空间冲突因素、机械运行条件与施工组织条件,构建吊物迹线的避障最小直角Steiner树(OARMST)模型,集成Dijkstra启发式算法和无载波通信(UWB)定位技术,开发起重作业迹线规划系统,求解多就位点、多障碍物下吊物的安全移动迹线。研究表明:OARMST模型求解的最优起重吊装安全迹线避免了起重作业的空间冲突风险,通过减少吊物转弯次数和位移,可防止吊物多次骤停摆动和驾驶员多余操作,提高起重作业的安全调度水平。

| Abstract: | In order to ensure safety and efficiency of lifting operation and reduce risks of its spatial conflicts,Manhattan plane of lifting operation was designed. Then,OARMST model of lifting trajectory was constructed by analyzing spatial conflict factors, mechanical operation conditions and construction organization conditions. Finally,lifting trajectory planning system was developed to explore safe moving trace of lifting objects under multiple sites and obstacles by integrating Dijkstra heuristic algorithm and ultra wide band( UWB) positioning technology. The research shows that the optimal moving trace obtained from OARMST model can avoid spatial conflicts,prevent multiple sudden suspensions of hanging objects and redundant operation of drivers by reducing turns and displacement of objects,therefore improving safe dispatching of lifting operation. |
