The tunnel cable fault method for inspecting of the present embodiment, rely on aforesaid tunnel cable fault inspection system to realize, as shown in Figure 5, this tunnel cable fault method for inspecting comprises the following steps:
(A) preliminary work: all parts is assembled according to Fig. 1, after inspection car is normally opened and is entered into tunnel, control module 3 in headstock 1 controls that lighting unit is opened, information acquisition unit starts to gather initial value, and control module 3 is according to the shooting angle of the information adjustment line-scan digital camera 4 gathered and shooting focal length.Meanwhile, the staff being positioned at pulpit inputs the calibration position of the initial kilometer of inspection car.
The concrete control of above-mentioned control module 3 pairs of line-scan digital cameras 4 is: the parameter value of the line-scan digital camera 4 when storing different distance between line-scan digital camera 4 and tunnel wall in the control module 3 of the present embodiment, such as, be provided with 19 groups of numerical value in the present embodiment altogether, as shown in table 1:
In above-mentioned table 1, camera lens is turned clockwise by 0 degree of-90 degree, and the focusing ring mark number of teeth, a number of teeth rotates to be 4.5 degree.As camera is initiated with 0 degree, shooting distance is 1 meter, and clear in subject shooting, camera lens is clockwise by 0 degree of rotation, 15 numbers of teeth, and a number of teeth is 4.5 degree, and so the anglec of rotation is 67.5 degree, that is: 15*4.5=67.5.Control module 3 is adjusted line-scan digital camera 4 by adjusting mechanism according to table 1.
(1) infomation detection: the information acquisition unit on inspection car carries out image acquisition to the cable in tunnel in real time under the cooperation of lighting unit, positioning unit detects the positional information of inspection car in real time simultaneously.
In addition, the laser range finder of information acquisition unit can distance between Real-time Collection inspection car and tunnel wall, photo electrical tacho generator 14 can detect in real time wheel the number of turns that turns, and send the range information detected to control module 3.
(2) information processing: control module is analyzed cable fault information and abort situation, stored after receiving the information of information acquisition unit collection and positioning unit;
In this step, the process of control module 3 pairs of information acquisition units is: the wheel information that the range information between the line-scan digital camera 4 that control module 3 real-time reception laser range finder collects and tunnel wall, photo electrical tacho generator 14 gather, and store, after storage, the information collected and last time are gathered the information stored to compare, obtain comparison result.Be specially: control module 3 is compared by the information of the tunnel inner cable image information obtained and the pathway of the cable under normal circumstances model database self stored, and finds out fault cable; Storage data in basic database in the information and control unit simultaneously detected by photo electrical tacho generator 14 are compared, and determine the cable broken down, and abort situation, for maintenance provides foundation.
The information processing of control module 3 pairs of photo electrical tacho generators 14 is: photo electrical tacho generator 14 then can detect the number of turns that wheel turns in real time, and the information of detection is real-time transmitted to control module 3, control module 3 can calculate the distance that inspection car travels, the position demarcated with the initial kilometer of staff's initial input compares the position that can obtain inspection car different time, namely the position of line-scan digital camera 4 pictures taken can be determined.Specifically be calculated as (setting inspection car from entering in tunnel at the uniform velocity travelling):
Calculated the operating range of vehicle by formula n=N/ (mT), wherein n is rotating speed, unit: rev/min; N is institute's meter pulse number in the sampling time (the signal number of laser velocimeter output); T is sampling time, unit: minute; The pulse number (be often referred to the number of teeth of test the speed code-disc) of m for often rotating a circle produced, usual m is 60, if m=60, so in 1 second, pulse number N is exactly rotating speed n.Speed v=2nR π (R is radius of wheel) can be tried to achieve after the rotating speed n obtained, and then can be inspection car running time in the hope of operating range S=vt(t).
(3) control to export: comprise
1. the result that analysis obtains is wirelessly transmitted to the Master Control Center of pulpit by control module 3, carries out output display to staff.Because control module 3 can find fault cable and abort situation, after therefore sending these information to control center, staff directly by situation display being seen tunnel inner cable, can know the position of fault cable simultaneously.In addition, can also set automatic recognition system in control module 3, carry out automatic identification marking to abort situation, detailed process is:
Image data is imported automatic recognition system, and cable pathway contours extract in the data gathered first occurs by automatic recognition system, contrasts the cable pathway model bank prestored, as inconsistent with normal cable pathway model, is then judged as there is fault (breakage).
2. to the control of line-scan digital camera 4: because in tunnel, ground is uneven, and width changes at any time, in order to ensure the shooting effect of line-scan digital camera 4, adjusting mechanism is in real time according to the width in tunnel, the shooting angle of height control line-scan digital camera 4 and shooting focal length under the control of control module 3, and this adjustment still adjusts according to table 1.Such as, when tunnel height broadens, laser range finder sends the range information detected to control module 3, this range information gathered and last range information are compared by control module 3, judge after comparison that the numerical value this time gathered is greater than the last numerical value gathered, can judge that tunnel width broadens, need the shooting focal length tuning up line-scan digital camera 4, now control module 3 exports control signal to micromotor, micromotor is made to rotate forward, and then drive camera lens focusing ring to rotate by focusing gear 11, light modulation gear 10 drives camera lens aperture ring to rotate, the focal length of line-scan digital camera 4 tunes up by final realization, ensure that line-scan digital camera 4 takes the clear of image.
(4) post-processed: staff adds up further according to the result of system automatic analysis, obtains finally correct result, and stores.
The present embodiment can carry out fast inspection to tunnel inner cable when not needing staff to enter tunnel, fault cable can not only be detected, the position of fault cable can be detected simultaneously, for the maintenance of staff provides reliable basis, ensure the safety of driving.
