The specific embodiment
Core of the present utility model provides a kind of detecting device of vehicle gauge, can realize the detection of vehicle dynamic gauge, and its accuracy of detection and efficient are higher.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, Fig. 1 is the testing process figure of detecting device in a kind of specific embodiment of vehicle gauge that the utility model provides.
In a kind of specific embodiment, detecting device of the present utility model comprises that the employing following steps detect:
Step 11: choose the position that vehicle gauge detects, the exterior contour that is in this position vehicle cross-sectional plane is carried out gauge detect;
Step 12: vehicle gauge detects comes down to the exterior contour of inspection positions vehicle cross-sectional plane is scanned, before measuring, at first should define a reference coordinate system as reference, in order to result of a measurement is indicated, and then the running condition by the position description vehicle of each check point on the exterior contour that is in above-mentioned cross-sectional plane in this reference coordinate system;
Step 13: the coordinate figure that records laser emission point, laser emission point is the position of emission laser, adopts the Laser emission method for scanning to obtain the relevant information of each check point during owing to measurement, therefore, should obtain the coordinate figure of laser emission point, so that follow-up calculating to the check point coordinate figure;
Step 14: obtain each check point to the distance of laser emission point by Laser emission scanning, and the angle between the line of described check point and laser emission point and one of them coordinate axle of described reference coordinate system;
Step 15: utilize the coordinate figure of laser emission point, check point to calculate the coordinate figure of each check point under reference coordinate system to line and the angle between one of them coordinate axle of the distance of laser emission point, described check point and laser emission point;
Step 16: draw the exterior contour of vehicle according to the coordinate figure of each check point, the exterior contour of described vehicle is vehicle gauge;
Step 17: the outside vehicle profile that drafting is obtained and the standard value of vehicle gauge compare;
Step 18: if the exterior contour of vehicle has exceeded the standard value of vehicle gauge, then execution in step 19, if do not exceed gauge, then return step 14 and proceed test;
Step 19: send alerting signal, the caution vehicle exceeds gauge, shows that vehicle exceeds the particular location of gauge, in order to the follow-up malfunction elimination that carries out of technical personnel, returns step 14 simultaneously and continues test, when the afterbody of vehicle during fully through the detection position, stops test.
Because the purpose of this utility model is in order to detect vehicle with respect to the gauge of track, so the definition of described reference coordinate system should be relevant with track.For example, described reference coordinate system can the vehicle cross-sectional plane and the intersection point of track centerline be initial point, be the y axle, be the x axle perpendicular to the direction of track with initial point direction straight up, then the coordinate figure of each check point is reference with the track, can reflect the position relation between vehicle and the track more truly, especially can improve the accuracy of detection of vehicle dynamic gauge.
Can adopt laser detecting apparatus that the exterior contour of vehicle is carried out Laser emission scanning, what need emphasize is that the check point on the outside vehicle profile generally is not need to go to select; Once you begin carry out gauge and detect, laser detecting apparatus all adopts the automatic scan range finding, in order to carry out the detection of vehicle gauge in real time, continuously, dynamically, rapidly; The quantity of check point is determined by the scanning accuracy of laser detecting apparatus on the outside vehicle profile, and for example, finishing 50 0 °, 0.5 °, 1.0 °, 360 ° scanning each second is different with finishing 50 0 °, 1 °, 2 °, 360 ° scanning each second.This automatic scan detection mode is than carrying out manual measurement at the selected check point of vehicle outline not only fast but also accurate.
