9. tunnel according to claim 8 cable fault method for inspecting,
it is characterized in that:in described step (three), also comprise the adjustment of control module to line-scan digital camera focal length: control module is according to focal length value corresponding to distance between line-scan digital camera and the tunnel wall of storage, output control signal is to force piece and rotating mechanism, controlling force piece drives focusing gear and light modulation gear to rotate, light modulation gear driven lens aperture ring rotates, focusing gear driven lens focusing ring rotates, simultaneously, control rotating mechanism is rotated, and making line-scan digital camera its focal length value within the scope of image acquisition is the numerical value prestoring in control module.
10. according to tunnel cable fault inspection system and method for inspecting described in any one in claim 6 to 9,
it is characterized in that:
1. described step () is also provided with step (A) before, that is:
(A) unit parts are installed on inspection car, control module is adjusted shooting angle and the focal length of line-scan digital camera in information acquisition unit, manually the reference position of inspection car is demarcated simultaneously;
2. step (three) is also provided with step (four) afterwards, that is:
(4) post-processed: staff further adds up according to the result of system automatic analysis, obtains final correct result, and storage.
