摘要:: 由于传统的轨道交通基坑隧道工程施工的人机械碰撞事故隐患突出,导致施工安全系数低和数据传输精度低等问题。对城市轨道交通工程基于 UWB 定位的人机防碰撞技术进行了研究,阐述了超宽带高精度定位技术在轨道交通基坑隧道工程施工中的现状,移动的机械设备通过定位标签实时生成虚拟电子围栏;根据无人机相较有人机管制操纵指令延迟的实际情况,分析并推导管制区域内无人机与有人机的防撞管制间隔;通过人员佩戴的定位标签与机械设备虚拟电子围栏发生位置信息交互,判断碰撞可能,实现提前预警。实验结果表明,该方法的定位系统误差最低为 9% ,数据传输精度高达 80% ,由此可知,采用基于 UWB 定位的人机防碰撞技术的数据传输精度更高,有效性更好。

Abstract:: Due to the prominent hidden dangers of human and mechanical collision accidents in the construction of traditional rail transit foundation pit and tunnel engineering , the construction safety factor is low and the accuracy of data transmission is low.This paper studies a man=machine anti-collision technology based on UWB positioning in urban rail transit engineering , and reports the current situation of UWB high-precision positioning technology in the construction of rail transit foundation pit and tunnel engineering and the situation that mobile mechanical equipment generates virtual electronic fence in real time through positioning labels ; According to the actual situation of control command delay of UAV compared with UAV , the anti-collision control interval between UAV and UAV in the control area is analyzed and deduced.Through the position information interaction between the positioning label worn by personnel and the virtual electronic fence of mechanical equipment , the possibility of collision is judged and early warning is realized ; The experimental results show that the minimum positioning system error of this method is 9% and the data transmission accuracy is as high as 80%.Therefore , the data transmission accuracy and effectiveness of human mechanical collision technology using this method are higher.
