Description
Technical field
The invention belongs to field of measuring technique, particularly vehicle overall dimension measuring instrument calibrating installation.
Background technology
Currently, part car owner is the purpose for reaching overload transportation, and various repackings are carried out to vehicle, such as thickeies steel to vehicle
Plate, increases vehicle dimension etc., the huge hidden danger as road traffic accident.Overload of vehicle transfinite turned into have a strong impact on country and
People life property safety, an outstanding problem for jeopardizing social economic order's stabilization.According to standard GB/T 1589-2004
《Road vehicle contour dimension, axle load and quality limit value》、GB7258-2012《Motor vehicle safe and technical specification》、
GB21861-2014《Vehicle Security checks project and method》Regulation, each public security vehicle management institute, motor vehicle peace
Full technology for detection mechanism, it is necessary to checked on from source, it is necessary to motor vehicles to new registration and motor vehicles it is outer
Wide size carries out compulsory test, and the motor vehicles for transfiniting after testing must not go up road.At present, the detection to vehicle overall dimension is basic
On still using manual measurement method, it is dangerous because the method for manual measurement wastes time and energy, measurement uncertain factor compared with
It is many, it is especially not objective, easily fake, GB21861-2014《Vehicle Security checks project and method》Clear stipulaties,
From in March, 2017, each Vehicle Security measuring station must use computer controls automatic measurement vehicle overall dimension
" vehicle overall dimension measuring instrument " measurement, contour dimension data of record motor vehicles and former with the contour dimension of the vehicle release
Beginning data (or the contour dimension initial data with the vehicle in public security vehicle administration office database) are compared and are judged automatically, from source
Strengthen the supervision and oversight to vehicle on head.
The existing method to vehicle overall dimension measuring instrument magnitude tracing is mainly by artificial using steel tape or laser
Stadia surveying one vehicle commander of tested vehicle, overall width, overall height, using this measurement data as " standard value ", then use vehicle gabarit
Gauging instrument measures the same vehicle commander of tested vehicle, overall width, overall height as " measured value ", " measured value " and " standard value " it
Difference is used as measurement error.The problem that this method is present mainly has：1st, as the tested vehicle of " standard set-up ", there can only be one
Vehicle commander, overall width, overall height value, need to prepare many various sizes of vehicles can cover the measurement model of vehicle overall dimension measuring instrument
Enclose, at detection scene it is difficult to ensure that finding so many various sizes of motor vehicles, to cover the survey of tested vehicle contour dimension
The measurement range for measuring instrument is difficult operation.2nd, " standard value " needs the peak of manual measurement vehicle, and the widest part, most strong point are time-consuming
Arduously, operation is difficult, and repeatability is relatively difficult to ensure card, and the uncertainty of measurement of " standard value " is much larger than steel tape or laser range finder
The uncertainty of measurement of itself.Use requirement (GB21861-2014 is not reached《Vehicle Security checks project and method》
It is required that vehicle commander, overall width, the uncertainty of measurement of overall height for ± 1%) 1/2, strictly speaking do not reach the essence of magnitude tracing requirement
Degree.3rd, " measured value " if measure by way of tested vehicle crosses vehicle overall dimension measuring instrument measured zone, then
Because the speed of test vehicle traveling is it is difficult to ensure that stablize at the uniform velocity, the route of traveling is it is difficult to ensure that consistent, the survey of vehicle commander and overall width
Amount repeatability it is difficult to ensure that, it is impossible to objectively reflect tested vehicle contour dimension measuring instrument metering performance.
