Abstract

The invention provides a vehicle-mounted appearance detection system and method for a communication leaky coaxial cable in a tunnel. The system comprises high-speed recognition cameras, laser range finders, image collecting devices and a controller; the high-speed recognition cameras, the laser range finders and the image collecting devices are arranged at the tops of the two sides of a train, the controller is connected with the high-speed recognition cameras, the laser range finders and the image collecting devices and is used for starting the laser range finder on the side at first preset time to measure the distance between the laser range finder and the communication leaky coaxial cable when one high-speed recognition camera at the top of one side of the train recognizes the communication leaky coaxial cable, adjusting the focal length of the image collecting device on the side according to the distance measured by the laser range finder on the side and starting the image collecting device on the side at the second preset time to collect image data of the communication leaky coaxial cable. Focal lengths of the image collecting devices can be adjusted in real time according to distance information measured by the laser range finders, and precision of collected images is improved.

Description

technical field [0001] The invention relates to the technical field of railway detection, in particular to a system and method for detecting the appearance of communication leaky cables in vehicle-mounted tunnels. Background technique [0002] With the rapid increase in the operating mileage of high-speed railways and ordinary-speed railway lines, the inspection workload of communication leakage cables in tunnels has also greatly increased. The existing inspection methods are mainly carried out by manual inspection on the road. The method has the following problems: [0003] There are many inspection items. The leaky communication cable in the tunnel is installed at a higher position in the tunnel. It is necessary to check the cable buckle, cable sheath, etc., and the workload of manual inspection is relatively large. The accuracy of the inspection is low. Because the skylight time of the high-speed railway and the general-speed railway line is mainly at night, the lighting...
