摘要: 针对目前国内带电作业中安全监控及预警手段和方法缺乏的现状,提出一种基于ToF(time of flight,飞行时间)技术的带电作业实时安全监测与预警系统。采用ToF摄像机实时对工作人员周围的空间进行三维重建,获取工作人员附近物体的坐标信息,进一步检测工作人员与身边物体的距离信息,当工作人员与导线等带电体的距离超过设定值时便会触发报警系统提醒操作人员。试验结果表明:该系统能实时、准确地监测距离,可靠地对危险情况进行提示与报警。

Abstract: Aiming at the deficiency of security monitoring and early warning means and methods for live working in China, a ToF (Time of flight)-based real-time safety monitoring and warning system is proposed for live working. The ToF camera is used for real-time 3D reconstruction of the space around working staff, and to obtain the coordinate information of topographic features surrounding the staff for further testing the distance information of staff and nearby objects, and when the distance between the staff and the charged body such as wires exceeds the set value, the alarm system will be triggered to remind the operators. The testing results show that the system can accurately monitor the distances in real time and provide reliably alarms about the dangerous situations.

Key words: live working, time of flight (ToF), safety distance, real-time monitoring, warning system
