Abstract: In recent years, State Grid Corporation of China has continuously expanded its power grid scale, with over 6000 projects under construction each year. During the peak construction period, nearly 100000 people work simultaneously, and more than 108000 projects with level three or higher risks are carried out each year. Due to the large number and wide scope of construction sites, the heavy task of power grid construction poses new challenges to safety management work. How to timely and effectively warn and predict unsafe behaviors of personnel, unsafe conditions of materials, unsafe conditions of the environment, and defects in management on the construction site, transforming "problem finding" into "risk prevention", and truly realizing the need to "inspect a project and ensure its safety" has become increasingly urgent.
