Abstract
A device for measuring automobile location angles through a laser scanning ranging method consists of a laser range sensor, a distance counter, a motion mechanism, an operation track and a computer controlling system. The laser range sensor and the distance counter are arranged on the motion mechanism. The motion mechanism track is arranged on two sides or one side of an automobile headlamp for detecting an onsite parking position and is parallel to a driving datum line. A signal output terminal of the laser range sensor and a signal output terminal of the distance counter are all connected with a data input terminal of the computer. The laser range sensor is vertical to the driving direction and is 4cm-6cm away from the earth. The measurement device runs on the track under the control of the computer and continuously scans and measures the distances between front and back wheels of the automobile to be measured and the laser ranging instrument. Angles between connecting lines of centers of front and back shafts and left and right wheels and the detection driving datum line are measured. And an error value of the automobile location angle is obtained. The automobile headlamp irradiation direction measurement can be modified afterwards. And an automobile carry moving plate can be driven to put the automobile precisely straight.
Description
Technical field
A kind of automotive inspection equipment is particularly a kind ofly accurately measured correct measurement and correction are carried out in realization to the car headlamp direction of illumination equipment by automobile being put the angle.
Background technology
When the car headlamp direction of illumination is measured, require automobile is placed on the position that is parallel to lane, otherwise will cause measurement data inaccurate.The method that generally adopts is with mechanical mechanism automobile to be moved on the position parallel with lane by force at present.This method not only complex structure, make installation cost height, low precision, and fail effectively to solve the problem of ajusting of oversize vehicle, can not adapt to growing Automobile Detection needs.
Summary of the invention
In view of the present situation that the car headlamp direction of illumination is measured, the purpose of this utility model is to design a kind of can the convenience by fitting operation, and device is ajusted in low cost of manufacture, the higher car headlamp direction of illumination measurement of measuring accuracy.
The utility model is a kind ofly to put the distance measuring equipment at angle with laser scanning and ranging method measured automobiles, it is characterized in that this device is made of laser range sensor, distance counter, motion, orbit and computer control system, laser range sensor, distance counter are installed on the motion, the motion track is installed in both sides or the side that car headlamp detects on-the-spot automobile parking position, be parallel to the driving datum line, the laser range sensor signal output part all is connected with the computer data input end with distance counter signal output part.
Laser range sensor is perpendicular to direction of traffic, apart from ground 4-6cm.During measurement, the device that the motion of laser range sensor, distance counter is installed orbits under computer control, and the distance of the front and rear wheel of the automobile to be checked parked and laser range finder is carried out continuous sweep measure.
This device adopts laser scanning and ranging, and the position of the front and back wheel of putting automobile is accurately measured, and records the forward and backward axle left and right wheels line of centres and the detection line drift angle of datum line of driving a vehicle, thereby obtains the error amount that automobile is put the angle.Can revise the measurement of car headlamp direction of illumination afterwards, also can drive a year car movable plate realization automobile and accurately ajust.
Before measuring, need at first measuring system to be carried out disposable calibration.Calibrate with the following method: follow the calibration plate that car datum line direction is put one group of high about 6-10cm, and guarantee that it overlaps with center line as far as possible, error is less than 1mm, by the orbiting of the left and right range finding telecontrol equipment of computer control, and the range data of continuous recording laser range sensor during to the different distance of calibration plate, measurement result is as the measuring system basic data.Calibration is removed calibration plate after finishing, and can begin to put parking a car measurement of angle.Calibration is disposable, does not change under the condition of position at track and distance measuring sensor, can forever use its calibration basic data.
Adopt above-mentioned measurement structure that the car headlamp direction of illumination is measured, its measuring accuracy height, detection speed are fast, have also reduced manually-operated simultaneously, can adapt to growing Automobile Detection needs.

Embodiment
Embodiment 1
As shown in Figure 1, the utility model is made of laser range sensor 1, distance counter 2, motion 3, orbit 4 and computer control system 5, laser range sensor 1, distance counter 2 are installed on the motion 3, orbit 4 is installed in the both sides that car headlamp detects on-the-spot automobile parking position, be parallel to driving datum line 6, the laser range sensor signal output part all is connected with the computer data input end with distance counter signal output part.In the present embodiment, laser range sensor 1 adopts HD-150 model, distance counter 2 to adopt the CD-J1 model, and computing machine adopts the P4 of association computing machine.
This device can be put the angle to vehicle wheel base, wheelspan and automobile and accurately measure, can revise the measurement of car headlamp direction of illumination afterwards, also can drive a year car movable plate realization automobile accurately ajusts, with the right side is example, before measuring, need at first measuring system to be carried out disposable calibration.Calibrate with the following method: see Fig. 2, follow car datum line direction and put the calibration plate of one group of high about 6-10cm, and guarantee that it overlaps with center line as far as possible, error is less than 1mm, by the orbiting of the left and right range finding telecontrol equipment of computer control, and the range data of continuous recording laser range sensor during to the different distance of calibration plate, measurement result is as the measuring system basic data.Calibration is removed calibration plate after finishing, and can begin to put parking a car measurement of angle
Moved to by the A point in the process that B orders at telecontrol equipment, laser range sensor 1 is found range to the wheel of the automobile parked continuously, and carries out the mileage counting simultaneously, can obtain forward and backward axle wheel difference to range finding
The continuous data of sensor distance can obtain the continuous data of left side front and back wheel to distance measuring sensor with quadrat method.Calculate according to calibration data and measurement data by computing machine, can obtain the left and right distance of taking turns the center of front axle to calibration center, obtain the left and right distance of taking turns the center of rear axle equally to calibration center, and obtain the wheelbase of forward and backward axle simultaneously, can obtain the forward and backward axle line of centres of automobile to be measured and the angle of driving datum line as calculated, promptly automobile is put angle.
Under situation, only need this device to be installed and get final product in a side of tested automobile to the front and rear wheel distance of a certain fixedly vehicle or known tested car.
When the direction of illumination to car headlamp detects, measure and proofread and correct the putting position of automobile, correct with the detection data of guaranteeing the headlamp direction of illumination.This device adopts laser scanning and ranging, and the position of the front and back wheel of putting automobile is accurately measured, and records the forward and backward axle left and right wheels line of centres and the detection line drift angle of datum line of driving a vehicle, thereby obtains the error amount that automobile is put the angle.
