Abstract: The electric power construction site requires extremely strict safety control to reduce safety accidents caused by misoperation. Based on artificial intelligence and AR technology, this paper constructs an intelligent identification system which is specially applied to power construction site monitoring. Based on convolution neural network algorithm, the system realizes real-time monitoring of personnel and equipment at the power construction site. It can meet the cooperation of different teams and different positions in the same scene. To a large extent, it has improved the ability of power employees to deal with emergencies and team cooperation, and provided sufficient guarantee for the safe construction of power.
