Abstract

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.

考虑空间冲突的起重作业轨迹规划模型

为了保证吊装作业的安全、高效，降低空间冲突的风险，ꎬ设计了吊装作业曼哈顿平面。然后，通过分析空间冲突因素ꎬ机械运行条件和施工组织条件，建立了举升轨迹ꎬOARMST模型。最后，结合Dijkstra启发式算法和超宽带(UWB)定位技术，开发了ꎬ举升轨迹规划系统，探索多场地、多障碍物下举升物体的安全移动轨迹。研究表明，由OARMST模型得到的最优运动轨迹可以避免空间冲突ꎬ通过减少物体的转弯和位移，防止悬挂物体的多次突然悬挂和驾驶员的重复操作ꎬ，从而提高吊装作业的安全调度。
