The fall of electric power operation scene is directly related to the life safety of aerial workers. In order to effectively warn the abnormal situation, an alarm method of electric power operation scene fall considering the long-distance dependence of local blocks is proposed. Firstly, the power operation scene fall alarm is divided into five grades, and according to the grade results, the rules of power operation scene fall danger zone delineation, warning signs, restricted traffic, safety equipment requirements and emergency plan are established, so as to establish risk warning indicators and complete power operation scene fall alarm. The experimental results show that the acceleration of power operation scene falling under no-load condition is higher than that under full load condition. This method can accurately identify the falling event and give an alarm in time, with high alarm accuracy and effect.
