The Safety Monitoring and Warning System for Live Working Based on ToF Technology

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.
