At present, the on-site safety monitoring of power is mainly monitored by personnel through the whole process of surveillance video, but the use of manual detection method is not only a waste of time, but also prone to missing the situation, so that the personal safety of staff cannot be guaranteed. In order to realize the intelligent recognition of workers' behavior on the job site, a dangerous behavior recognition technology based on OpenPose was proposed. The method extracts the key bone information of electric workers from video stream images, uses deep neural network to realize the human behavior and posture perception of electric workers in multi-person scenarios, detects and recognizes the violations of construction workers in real time, and issues warnings. The proposed method realizes the accurate and real-time safety monitoring of the power field operators' behavior, guarantees the personal safety of the field operators and the smooth progress of the power operation, and has certain robustness and generalization ability.
