The detection equipment has the problems of more blind spots, easy false or missing information and the like. Therefore, the efficiency of detection by manpower and equipment cannot be adapted to the characteristic of short detection window time of modern subway tunnels.
In order to improve the detection efficiency and the detection effect, the tunnel cable temperature detection based on the infrared image processing technology has been applied to a certain extent. The tunnel detection vehicle can dynamically detect by using the tunnel detection vehicle provided with the detection equipment under the condition of not closing the road.

In addition, the traditional fault positioning mode can only judge the position range of the cable with abnormal temperature rise by judging the position of the inspection trolley, so that the fault position of the cable can not be specifically judged or the cable can be positioned to be specific, and the overhaul difficulty of subsequent operators on the cable is increased.
