The utility model discloses to be surveyed each wheel base of vehicle and measure in the section at one time and accomplish, and greatly improve detection efficiency, reduce the manual operation error, the resolving power be 1mm, measuring error, 1 percent.
Description
Technical field
The utility model relates to technical field of automobile measurement, specifically a kind of vehicle wheelbase self-operated measuring unit.
Background technology
According to the standard GB/T 21861-2014 " Vehicle Security Interventions Requested and method " that on March 1st, 2015 implements, require automatically to measure vehicle overall dimension, clear stipulaties in a standard: on March 1st, 2017, heavy medium truck, special Operation Van, trailer use contour dimension self-operated measuring unit.Measuring vehicle wheelbase is needed to cargo vehicle and trailer, standard clear stipulaties: measure with dimensional measuring instrument; When having ready conditions, self-operated measuring unit can be used.
At present, motor vehicle detecting department many employings manual measurement method, utilizes the instrument such as plummet and tape measure measuring vehicle wheelbase, needs more than two people to work in coordination with, and wastes time and energy and accuracy of detection is lower.
Summary of the invention

As further program of the utility model: the distance of the wheel of described laser range scanners and tested vehicle is 0.3-9m, the height on laser range scanners distance ground is 5-30cm.
As the utility model further scheme: the laser scanning face of described laser range scanners is parallel with measuring table or ground, described laser scanning face is vertical with the travel direction of tested vehicle simultaneously.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has been measured in the wheelbase of each axle of tested vehicle at one time section, greatly improves detection efficiency, reduces manual operation error, and resolving power is 1mm, metrical error <1%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram that the utility model detects vehicle.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-2, a kind of vehicle wheelbase self-operated measuring unit, comprise industrial computer and laser range scanners 3, described laser range scanners 3 connects described industrial computer by communication facilities, communication facilities adopts Ethernet interface, facilitate the system integration and high-speed communication, described laser range scanners 3 is arranged on measuring table or ground 1.
Described laser range scanners 3 is 0.3-9m with the distance of the wheel of tested vehicle 2, laser range scanners 3 is 5-30cm apart from the height on ground, the laser scanning face 4 of described laser range scanners 3 is parallel with measuring table or ground 1, described laser scanning face 4 is vertical with the travel direction of tested vehicle 2 simultaneously, guarantee that the laser beam flying of high-velocity scanning returns valid data, to realize not stopping fast measurement to wheel.
Described vehicle wheelbase self-operated measuring unit in use, after tested vehicle 2 sails measuring table or ground 1 into, laser range scanners 3 is in open state always and obtains the range data of laser to the wheel of tested vehicle 2, the sweep limit of laser range scanners 3 180 °, return one group of range data every 0.25 °, exist according to laser range scanners 3
distance value when=90 °, judges that laser range scanners 3 is between two axles of tested vehicle 2; When laser scanning is to wheel 5, the distance of vertical vehicle heading
substantially constant, consider wheel shape and test error, according to
setting threshold limit value, in conjunction with the distance of parallel cart travel direction
, can calculate the length of wheel 5 line segment crossing with laser scanning face 4, and then line taking section mid point is the center of a wheel, now wheel to laser range scanners 3 along the distance in wheelbase direction is
, recording this value is L
1; When laser scanning is to wheel 2, the distance of vertical vehicle heading
substantially constant, according to
setting threshold limit value, in conjunction with the distance of parallel cart travel direction
, can calculate the length of wheel 6 and the crossing line segment in laser scanning face 4, and then line taking section mid point is the center of a wheel, now wheel to laser range scanners 3 along the distance in wheelbase direction is
, recording this value is L
2; Distance L under computer recording
1and L
2after, addition calculation obtains vehicle wheelbase L=L
1+ L
2.For multiple-axle vehicle, when judging that laser range scanners 3 is between two axles of tested vehicle 2 successively, calculate the adjacent diaxon wheelbase of vehicle, wheelbase computation and measurement time <2s; Namely tested vehicle 2 low speed enters wheelbase measured zone, laser range scanners 3 is by returning the data variation of 180 ° of range signals, judge that laser range scanners 3 is between the diaxon of tested vehicle 2, utilize measurement data to realize the measurement of vehicle wheelbase by coordinate transform.
The utility model has been measured in the wheelbase of each axle of tested vehicle 2 at one time section, greatly improves detection efficiency, reduces manual operation error, and resolving power is 1mm, metrical error <1%.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
