Abstract

The invention discloses a light curtain measuring device and a method for vehicle exterior dimension, which relate to the technical field of measuring. The device comprises a length measuring light curtain, a height measuring light curtain and a width measuring light curtain which are connected with a controller; the length measuring light curtain is installed in a measuring channel. The height measuring light curtain is vertically arranged in the measuring channel. The width measuring light curtain comprises a width measuring light curtain receiver and a width measuring light curtain emitter. The width measuring light curtain receiver is arranged above the measuring channel while the width measuring light curtain emitter arranged below the road surface of the measuring channel. The light curtain formed by the width measuring light curtain receiver and the width measuring light curtain emitter forms an acute angle with the road surface of the measuring channel. The measuring method measures the exterior dimension of a vehicle such as width, length and height through the use of light curtains. Compared with the prior art, the device and the method reduce the influence of the traveling speed of a vehicle during the measurement, achieve small measuring errors and saves time and labor.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a device and a measurement method for measuring the outer dimension of a vehicle by using a light curtain. Background technique [0002] According to the national standard GB7258-2012 "Motor Vehicle Operation Safety Technical Conditions", GB21861-2014 "Motor Vehicle Safety Technical Inspection Items and Methods", GB 1589-2004 "Road Vehicle Outline Dimensions, Axle Load and Quality Limits", in order to Check at the source, all public security vehicle management offices and motor vehicle inspection stations must conduct mandatory inspections on the outer dimensions of newly registered vehicles and in-use motor vehicles that exceed the limit; It is necessary to detect various vehicle outline dimensions that exceed the limit. [0003] At present, the detection of vehicle outline dimensions basically still uses manual measurement methods, using measuring tools such as tape measur...
