Abstract: This paper proposes a behavioral safety control system for substation operators based on Beidou positioning, which is based on the safety of on-site operations and the difficulty of personnel control in the current substation operation. This system first uses advanced 3D laser scanning technology to complete the three-dimensional modeling of the substation, construction of three-dimensional digital map. Then, Ultra Wideband(UWB)+ Beidou integrated positioning technology is used to achieve high-precision positioning of the substation indoor and outdoor. Finally, the smart bracelet and Beidou positioning terminal are combined with the power work ticket, and the bracelet and Beidou positioning terminal are associated with the person in charge of the work and the members of the work team one by one, so as to realize real-time positioning of the substation operators and real-time monitoring of behavioral safety, which can remotely and effectively control the entire operation site situation, and control the operational safety risks.
