Embodiment Construction

[0015] The structure of the present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0016] Referring to Figure 1, a non-contact detection system for vehicle size is mainly composed of a vehicle body length measuring device, a vehicle body length measuring device (A), a vehicle body width measuring device (B), a vehicle body height measuring device (C) and a measurement and control system (D )composition.

[0017] With reference to Fig. 2, 3, described vehicle body length measuring device (A) is made up of 3 all identical measuring units of the same structure of inline arrangement, and this measuring unit is arranged on frame (9) level by camera turntable (2). The camera (1) on the guide rail (7), a transmission mechanism for driving the camera (1) to move along the horizontal guide rail (7), and a displacement sensor (5) for measuring and recording the displacement of the camera (1).

Abstract

The present invention relates to a complete vehicle size non-contacting quick detection system. It includes vehicle body length measuring device formed from three camerae placed on the longitudinal horizontal guideway frame and displacement sensor for feeding back displacement of camera, vehicle body width measuring device formed from camera placed on the transverse horizontal guideway frame and displacement sensor for feeding back displacement of camera, vehicle body height measuring device formed from camera placed on the vertical guideway frame and displacement sensor for feeding back camera displacement and computer measurement control system for connecting all the camerae and sensors.

Description

technical field [0001] The invention belongs to automobile performance detection equipment, in particular to a non-contact detection system for the size of a whole automobile. The so-called vehicle size refers to the length, width and height of the car body, the length, width and height of the car body, and the wheelbase of the car. Background technique [0002] my country's "Comprehensive Performance Requirements and Inspection Methods for Commercial Vehicles" (GB18565-2001) requires inspection of vehicle size parameters in the vehicle maintenance inspection project, and the structure of the vehicle must not be modified arbitrarily. For the vehicles in use, the vehicle management department should combine the annual inspection of the motor vehicle comprehensive performance testing station and re-check the relevant parameters of the vehicle's external dimensions according to the national standards for the inspection of commercial vehicles, and supervise and put an end to the...
