Problems solved by technology

[0005] At the same time, the above-mentioned detection of the cable can only detect the performance indicators of the cable, such as whether there is signal transmission, whether there is a standing wave ratio, etc., and cannot detect whether the cable is damaged in appearance or whether the fixing fixture is detached. And then can't prevent the danger caused by the cable falling off to driving

Abstract

The invention discloses a tunnel cable fault inspection system and method. The tunnel cable fault inspection system comprises an automatic running inspection vehicle and a locating unit for locating the inspection vehicle, wherein a control unit in wireless connection with a main control center of a control room, a signal acquisition unit for inspecting a cable in a tunnel, an illuminating unit for providing illumination for the signal acquisition unit, and a power supply unit for providing electrical energy are fixedly arranged on the inspection vehicle; the signal output end of the signal acquisition unit is connected with the signal input end of the control unit, the power supply unit is connected with the power ends of the control unit, the signal acquisition unit and the illuminating unit respectively; the signal output end of the locating unit is connected with the control unit. The tunnel cable fault inspection system has a simple structure, can automatically and completely inspect cables without requiring a worker to enter tunnels, can timely find cables with damaged appearance and cables with opened or falling clamps, and can timely maintain the cables to ensure travelling safety. The tunnel cable fault inspection system is suitable for inspecting cables in various road and bridge tunnels.

Description

technical field [0001] The invention belongs to the field of tunnel detection, and relates to a tunnel cable detection device, in particular to a tunnel cable fault inspection system, and at the same time, the invention also relates to a corresponding tunnel cable fault inspection method. Background technique [0002] Currently, tunnels are an important part of transportation. The tunnel is generally equipped with various cables such as communication cables and power supply cables. After these cables have been in operation for a long time, failures such as cable damage and shedding may occur due to various reasons, such as the pressure caused by vehicles driving at high speed in the tunnel. Wave and micro-pressure fluctuations and shocks, or damage to cables caused by natural disasters such as water seepage, freezing and thawing, once there is a problem with the line, it will have a serious impact on driving. [0003] In order to prevent the impact of cable failures on the ...
