The invention discloses a power distribution network field operation video intelligent safety control method driven by a knowledge graph, and the method comprises the steps: firstly constructing a power operation safety control knowledge graph, and aims to decompose objects, flows, matters needing attention and other semantic information in an operation task, thereby enabling the operation to be more visual and visualized; establishing a basis for subsequent personnel information security matching, skill point action matching and dynamic evaluation; dividing a power grid operation site area and a video intelligent management and control category; finally, using a deep learning algorithm, monitoring videos of all areas of an operation site are combined, safety control is conducted on operators in the whole process in real time, original passive on-site operation manual supervision is changed into active intelligent automatic monitoring, support is provided for early warning of on-site operation safety risks, and therefore the risks of the on-site operators are reduced, and the safety of the operators is improved. Therefore, the method is of great significance to the improvement of the safety management and control level of the power distribution network on-site operation.
