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 a corresponding tunnel cable fault inspection method. The control unit wirelessly connected to the control center, the signal acquisition unit used to inspect the cables in the tunnel, the lighting unit used to provide lighting for the signal acquisition unit, and the power supply unit used to provide electric energy, the signal acquisition unit The signal output end is connected to the signal input end of the control unit, and the power supply unit is respectively connected to the power end of the control unit, the information collection unit, and the lighting unit; it also includes a positioning unit for positioning the inspection vehicle, and the signal output of the positioning unit connected to the control unit. The invention has a simple structure, and can automatically complete the inspection of the cables without manually entering the tunnel, and can timely find the cables with damaged appearance, open clamps, and falling off cables, and perform maintenance in time to ensure driving safety. The invention is suitable for detecting cables in various road 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 also relates to a corresponding tunnel cable fault inspection method. Background technique [0002] At present, tunnels have become an important part of transportation. Tunnels are generally equipped with communication cables, power supply cables and other cables. After long-term operation of these cables, failures such as cable damage and falling off may occur due to various reasons, such as the pressure caused by vehicles traveling at high speed in the tunnel. Waves and micro-air pressure fluctuations and shocks, or damage to cables caused by natural disasters such as water seepage, freeze-thaw, etc., 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 faults on vehicle operation, railway personnel need to regu...
