Trajectory planning model for lifting operation considering spatial conflict
In order to ensure safety and efficiency of lifting operation and reduce risks of its spatial conflictsꎬ Manhattan plane of lifting operation was designed. Thenꎬ OARMST model of lifting trajectory was constructed by analyzing spatial conflict factorsꎬ mechanical operation conditions and construction organization conditions. Finallyꎬ 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 中 国 安 全 科 学 学 报 China Safety Science Journal 第30卷 2020年 ultra wide band (UWB) positioning technology. The research shows that the optimal moving trace obtained from OARMST model can avoid spatial conflictsꎬ prevent multiple sudden suspensions of hanging objects and redundant operation of drivers by reducing turns and displacement of objectsꎬ therefore improving safe dispatching of lifting operation.
