Abstract: When Baihetan cable crane is pouring dam concrete, the site situation is complex and the collision risk is very high due to the distribution of formworks, steel bars and construction machines on the dam surface. At the same time, the cable crane pouring is arduous and it is easy to cause distraction and fatigue of drivers, which threatens the safety of cable crane operation. In view of the above situations, a cable crane safety monitoring system with three modules of anti-collision, target position limitation and anti-fatigue functions was developed. In this system, the dynamic information of cable machine, tower crane and three-dimensional image information of warehouse surface were connected by anti-collision and target position limiting function, then the data model and algorithm were constructed in the system server to analyze the position information of cable machine, tower crane and pouring surface. At the same time, it was supplemented by anti-fatigue function to carry out dynamic monitoring on the operator's working state. The system can comprehensively analyze the risks in the running process of the cable machine, and take timely alarm, deceleration or shutdown measures. The key and difficult points of this system lie in the precision control of dynamic data acquisition, and the conversion and analysis after data acquisition. After the system was put into use, the concrete pouring efficiency of Baihetan Hydropower Station significantly improved, which is worthy of reference for similar projects.
