1/2.Linear measure longimetry principle is consistent with width measure principle, is not repeated.The vehicle of process is carried out to high speed dynamic scan, and moment (0.6 second) calculates width and the height of load-carrying vehicle; Then, stepper motor support (1) drives vehicle ' s contour scanner (17) 90-degree rotation (0.2 second), proceeds high speed dynamic scan, and moment (0.6 second) calculates the length of load-carrying vehicle.Truck outline self-operated measuring unit has the function whether wide height of fast detecting vehicle transfinites, even also can Measurement accuracy under rugged surroundings.
Accompanying drawing explanation
Fig. 1 is the assembly scheme of installation of truck outline self-operated measuring unit.Wherein: 1, stepper motor support, 15, ground induction coil, 16, portal frame, 17, Vehicle length scanner, 18, data acquisition cabinet, 19, the computing machine of weighing, 20, LED screen, 21, power amplification plate, 22, loudspeaker.
Embodiment,
During concrete enforcement, truck outline self-operated measuring unit is weighed with truck and vehicle information acquisition system is one.Vehicle ' s contour scanner (17) adopts German Sick LMS111 outdoor laser scanning radar.The defect of this scanning laser radar is can only one direction.It mainly contains following features:
1. volume is little, lightweight, and convenient installation is integrated.
2. adopt many echo techniques, better filter external interference, measure more reliable.
3. there is self-checking function, guarantee the normal operation of equipment.
4. adopt 1 level laser, harmless to human-body safety.
5.270 ° of scanning angles, more scanning area.
6.IP67 degree of protection, assurance can be for outdoor atrocious weather.
7. inner integrated heater, can be-30 ℃ of uses.Angular resolution reaches 0.25 degree/0.5 degree (adjustable), makes data more accurate.
8. sweep frequency reaches 25HZ, guarantees the vehicle in travelling to scan completely.
LED screen (20) selects 5 row to show LED screen, shows respectively car plate, car weight, overall width, overall height and the number of axle.
It is example that specific embodiment be take the capital entrance ZZQCKGCL2011-1 of large high speed high speed Datong District truck outline self-operated measuring unit, illustrates: the direction of arrow is the detection track Way in of truck outline self-operated measuring unit.From left to right, install backward successively.That ground induction coil (15) is arranged under the road surface of detecting track foremost.Next is that two pillars of portal frame (16) are arranged on the both sides of detecting track, and the direction of portal frame (16) is perpendicular to the direction that detects track.Stepper motor support (1) is installed downwards in the middle of the top of portal frame (16), and stepper motor support (1) is mounting vehicle profile scan device (17) below, the vertical ground induction coil of vertical line (15) of vehicle ' s contour scanner (17).The height of portal frame (16), meeting vehicle ' s contour scanner (17) is 9 meters apart from the height of inspection vehicle road surface.To detect the data acquisition cabinet (18) of left side, track safety island and the computing machine of weighing (19) and the power amplification plate in duty room again.Detecting left side, track safety island is LED screen (20) and loudspeaker (22) more at a distance.
The principle of the wide high measurement of load-carrying vehicle
1, vehicle ' s contour scanner (17) is 9.2 meters apart from the height of inspection vehicle road surface, and enough height guarantee to scan the overall picture of car; Starting stage vehicle ' s contour scanner (17) scanning cross-section becomes 90 degree angles (vertically) with track direction, after 0.7 second, stepper motor support (1) drives vehicle ' s contour scanner (17) scanning cross-section to become 0 degree angle (parallel) with track direction, the plumbness of again replying subsequently.
2, in the time of under vehicle head process vehicle ' s contour scanner (17), ground induction coil (15) is located, and system and device starts, and starts to measure, and with the speed of 25 times/second, scans, and 540 data are returned in each scanning.In the time of under the tailstock leaves vehicle ' s contour scanner (17), finish to measure.
3, consider the impact of the speed of a motor vehicle on scanning, and remove interference according to scanning drop, and the adjustment of some empirical values, finally calculate the length of vehicle.
4, the software application Delphi of this truck outline self-operated measuring unit device exploitation, its operational efficiency obtains industry and generally acknowledges.And native system is through actual test and the optimization of up to a million cars, its error rate < 1% accuracy rate > 99%.
The detection software that transfinites is installed in the computing machine of weighing (19), the data upload of vehicle ' s contour scanner (17) is to the detection software that transfinites, whether detect software synchronization by the length of detected vehicle, by LED large screen display and voice system, reporting this vehicle transfinites.Transfinite detect software integrate mainly refer to transfinite detect software how with meter reset for and the wide Gao Yi of vehicle be used in conjunction with, accomplish seamless link.Concrete steps are as follows: the detection software that transfinites is reseted preparation every 100ms to meter and gone out inquiry unit status command, obtains coil state, has judged whether vehicle process.When having vehicle through out-of-date, start wide Gao Yi, laser starts scanning car.When vehicle has passed through coil completely, coil signal disappears, and stops wide Gao Yi, and obtains the wide high data of vehicle.At the detection software that transfinites, obtain after complete meter tuple certificate and wide high data, start follow-up work, as data library storage, large-size screen monitors demonstration, voice broadcast etc.
The usefulness of truck outline self-operated measuring unit of the present invention is to adopt German import scanning laser radar measuring equipment, use ripe distance to equal time * laser light velocity principle, non-contact detecting, the vehicle of process is carried out to high speed dynamic scan, moment calculates width height and the length of vehicle, there is the wide high long function whether transfiniting of fast detecting vehicle, even also can Measurement accuracy under rugged surroundings.
