Multiple Time Scale and VR Based UAV Inspection Method for Bird-involved Faults of Transmission Lines
With the increase of power demand,the coverage of transmission lines has gradually expanded,and the probability of fault occurrence is also increased,especially bird-involved faults.The increase in the number of bird droppings,bird nests,etc.may lead to short circuit and short circuit faults on the line,affecting the normal operation of the transmission line.In or-der to improve the accuracy of bird-involved fault judgment and ensure the stable operation of transmission lines,a study on the UAV inspection method for bird-involved fault of transmission lines based on multiple time scales and virtual reality(VR)is proposed.Based on the division of multiple time scales according to the law of bird activity,the UAV is used to obtain the transmission line image and match it.The VR technology is used to build the transmission line 3D virtual scene,load the bird-involved fault feature set,measure the similarity between it and the virtual scene,determine the specific category and location of the bird-involved fault,and generate alarm information,thus realizing the patrol inspection of the transmission line bird-in-volved fault.The experimental data shows that the minimum matching cost of the transmission line inspection image obtained by the proposed method is 2,and the bird-involved fault judgment result is closer to the actual result,which fully proves that the proposed method has better inspection effect.
