Abstract: Because the leaky coaxial cable is mainly laid in the sections with poor wireless signal coverage, such as railway tunnels and curves, and high-speed train operation may cause the wind tunnel effect, the leaky cable and fixed components are easy to cause looseness, falling off and other situations, and there are serious driving safety risks. In this paper, the onboard image intelligent detection system for leakage coaxial cable is studied, and the system is applied to the actual inspection work to improve the detection quality, detection efficiency and personnel efficiency.
