Network congestion control method and system for unmanned aerial vehicle inspection of power transmission line

The invention relates to a network congestion control method and system for power transmission line unmanned aerial vehicle inspection, and belongs to the field of unmanned aerial vehicle power system power transmission line inspection. An unmanned aerial vehicle self-organizing network architecture is constructed, and whether an intermediate node is congested or not is judged in the process of sending information from a source node to a destination node; when congestion occurs, the data transmission priority is determined according to a priority algorithm to perform sequential transmission, a back pressure signal is broadcasted to the neighbor node to reduce the information transmission rate of the neighbor node to realize congestion control, and according to the current congestion rate of each node, the node needing to transmit data reselects a transmission path through an AODV routing protocol to avoid congestion, so that the data transmission efficiency is improved. The whole process comprises network con
