The invention provides an active anti-collision method and system for a crane cart, and relates to the technical field of crane anti-collision. According to the active anti-collision method and system, surrounding environment information is captured in real time through a high-precision and non-contact laser scanning technology aiming at various collision risks possibly occurring in the running process of the crane; and the acquired point cloud data is subjected to coordinate conversion, downsampling, clustering analysis and other preprocessing operations, so that the contour size and coordinates of the obstacle can be accurately identified. On the basis, the active anti-collision method and system can intelligently set and dynamically adjust the sizes of protection areas of different levels in combination with the actual operation state of the crane walking mechanism, it is ensured that response can be rapidly made under any working condition, mutual collision between machines, between a machine and a person or between a machine and an obstacle is effectively prevented, and the safety of the crane is improved. And the safety level and the overall working efficiency of the crane cart in the running process are improved.

    本发明提供了一种起重机大车主动防撞方法与系统,涉及起重机防撞技术领域。针对起重机在运行过程中可能出现的各种碰撞风险,本主动防撞方法与系统通过高精度、非接触式的激光扫描技术实时捕捉周围环境信息;并通过对获取的点云数据进行坐标转换、降采样、聚类分析等预处理操作,以实现对障碍物轮廓尺寸和坐标的精确识别。在此基础上,本主动防撞方法与系统能够结合起重机行走机构的实际运行状态智能设定并动态调节不同级别的保护区域大小,确保在任何工况下都能迅速做出反应,有效防止机与机之间、机与人之间或机与障碍物之间的相互碰撞,提升起重机大车运行过程中的安全水平和整体工作效率。
