Abstract: The power industry is an important energy and basic industry in the country, and the safe operation of the power grid is related to the national economy and people's livelihood. Power transmission and transformation equipment undertakes the important task of electricity transmission in the power grid. Power transmission and transformation operators are the main force in maintaining the safe operation of the power grid. Operators who work in complex outdoor conditions for a long time are prone to encountering sudden emergencies, or experiencing mental illness, physical exhaustion, and other unsafe incidents in the power grid during the operation process, At present, there is a lack of effective monitoring and early warning methods for the work status, physical condition, and safety precautions of power transmission and transformation maintenance workers. This article analyzes the current situation of power transmission and transformation workers, and starts with solving the problem of difficulty in effectively monitoring and warning the work status, physical condition, and safety precautions of workers. It proposes an exploration and research content of a work safety bracelet based on the Beidou satellite navigation system in power transmission and transformation work safety precautions. Combining with the current industry situation, it provides ideas for safe and efficient work safety precautions。
