Description
Technical Field
The invention belongs to the technical field of measurement, in particular to a calibration device of a vehicle outline dimension measuring instrument.
Background
Currently, in order to achieve the purpose of overload transportation, some car owners perform various refitting on the vehicles, such as thickening steel plates of the vehicles, enlarging the sizes of the vehicles and the like, and become a great hidden danger of road traffic accidents. Overload and overrun of vehicles have become a prominent problem that seriously affects the life and property safety of countries and people and endangers the stability of social and economic orders. According to the specifications of national standards GB1589-2004 (road vehicle outline size, axle load and quality limit), GB7258-2012 (motor vehicle operation safety technical condition), GB21861-2014 (motor vehicle safety technical inspection project and method), each public security vehicle administration institute and motor vehicle safety technical detection mechanism must be closed from the source, the outline size of a newly registered motor vehicle and a motor vehicle in use must be forcedly detected, and the motor vehicle with the detection overrun must not be on the road. At present, a manual measurement method is still basically adopted for detecting the vehicle outline size, and because the manual measurement method is time-consuming and labor-consuming, unsafe, has more measurement uncertainty factors, is not objective and easy to falsify, and is clearly specified in GB21861-2014 motor vehicle safety technology inspection project and method, since month 3 in 2017, each motor vehicle safety technology detection station must use a computer to control a 'vehicle outline size measuring instrument' for automatically measuring the vehicle outline size to measure and record the outline size data of the motor vehicle and automatically compare and judge with the outline size original data of the vehicle leaving the factory (or the outline size original data of the vehicle in a public security vehicle management database), so that the management and supervision of the vehicle are enhanced from the source.
The existing method for tracing the magnitude of the vehicle outline dimension measuring instrument mainly comprises the steps of manually measuring the length, width and height of a measured vehicle by using a steel tape measure or a laser range finder, taking the measured data as a standard value, and then measuring the length, width and height of the same measured vehicle by using the vehicle outline dimension measuring instrument as a measured value, and taking the difference between the measured value and the standard value as a measurement error. The problems with this approach are mainly: 1. as the tested vehicle of the standard device, only one vehicle length, vehicle width and vehicle height value can be provided, a plurality of vehicles with different sizes can be prepared to cover the measuring range of the vehicle outline measuring instrument, the fact that a plurality of motor vehicles with different sizes are found on a detection site is difficult to ensure, and the measuring range of the vehicle outline measuring instrument to be tested is difficult to operate. 2. The standard value is required to manually measure the highest point, the widest part, the longest part, time and labor waste, difficult operation, difficult guarantee of repeatability, and the measurement uncertainty of the standard value is far greater than that of a steel tape or a laser range finder. The use requirement (GB 21861-2014, motor vehicle safety technology inspection project and method, requires 1/2 of uncertainty of measurement of vehicle length, vehicle width and vehicle height to be +/-1%) is not met, and the accuracy of the magnitude tracing requirement is not strictly met. 3. If the measured value is measured by the way that the measured vehicle passes through the measuring area of the vehicle contour measuring instrument, the running speed of the test vehicle is difficult to ensure stable and uniform speed, the running route is difficult to ensure consistency, the measuring repeatability of the vehicle length and the vehicle width is difficult to ensure, and the measuring performance of the measured vehicle contour measuring instrument cannot be objectively reflected.
