Analysis And Application Of Inspection Technology For Power Unmanned Aerial Vehicle

In recent years,the smart grid in State Grid Corporation has a rapid development.The traditional inspection mode on transmission line has been unable to meet the actual needs of grid development.With the helicopter inspection in State Grid is widespread gradually,the application of UAV inspection technology has been increasingly used.The most popular inspection mode is artificial checking.It is not only labor-intensive,but also time-consuming.Some sections of the line cannot be checked due to topography factor,which will be resulting in maintenance difficulty.In order to eliminate the blind spot of artificial checking as well as improve inspection efficiency,the comprehensive UAV transmission line checking work will be gradually implemented.According to the comparative analysis between domestic and foreign UAV inspection applications,combined with transmission line technical factor on UAV applications,this paper analyzed the current application circumstance on specific electrical UVA.Meanwhile,this paper researched scope of various types of UVA and standardized inspection process.In addition,the solution of difficult sections that cannot be inspected by people will be shown on the paper.At present,the types of inspection project on transmission line by UAV mainly includes: towers and channel inspections,,inspection of abnormal matters on the ground wire,crossing of transmission lines,infrared thermal imaging anti-mountain fire inspection,heavy-duty line temperature inspection,mined areas as well as special area inspection,line fault emergency inspection and so on.Since there are many gully,hill and mountain areas in Shanxi province.In this paper,it is studied the hybrid positioning signal guarantee technology in the gully area,which could improve the safety when the satellite is rare or lost.Furthermore,the bionic visual analysis of artificial intelligence collected by the UAV inspection data are summarized in paper,the efficiency of UAV recognition processing on inspection data will be enhanced by this way.The research results on this paper can effectively achieve the comprehensive and intelligent inspection of UAV.The result can also provide a scientific,effective and safe means for the inspection of transmission lines.In terms of working efficiency,operation speed and operation level,inspection quality,will be fully developed by the research outcome.
