Automobile external contour size measurement system

Abstract

The invention discloses an automobile external contour size measurement system. The system comprises a measurement platform, touch sensors, an infrared emitter and an infrared receiver; the touch sensors are in over-against arrangement and can be arranged on the measurement platform in a synchronous movement way and used for measuring the vehicle length and width; the infrared emitter and the infrared receiver can be telescopically arranged on the measurement platform; the infrared receiver is used for receiving an infrared beam of the infrared emitter so as to acquire the vehicle height by measuring telescopic height of the infrared emitter and the telescopic height of the infrared receiver. The automobile external contour size measurement system provided by the invention controls the lifting of lifting rods through a control center, the infrared emitter and the infrared receiver are mutually cooperated and sensed to perform automobile contour height measurement; the touch sensors areused for touching four sides of the body so as to perform body width and length measurement, and the measurement way is optimized; in comparison with the artificial measurement in the prior art, thevehicle is intelligently measured, and more precise body contour numerical value is acquired.

Description

technical field [0001] The invention relates to the technical field of automobile measurement, in particular to a measurement system for automobile outline dimensions. Background technique [0002] In today's society, in order to achieve the purpose of overloaded transportation, some car owners carry out various modifications to the vehicle, such as thickening the steel plate of the vehicle, increasing the size of the vehicle, etc., which has become a huge hidden danger of road traffic accidents. Vehicle overloading has become a prominent problem that seriously affects the safety of the country and people's life and property, and endangers the stability of social and economic order. [0003] At present, the detection of vehicle outline dimensions basically still adopts the method of manual measurement, because the method of manual measurement is time-consuming, laborious, unsafe, and there are many uncertain factors in measurement, especially the measurement results are not ...

Problems solved by technology

[0003] At present, the detection of vehicle outline dimensions basically still adopts the method of manual measurement, because the method of manual measurement is time-consuming, laborious, unsafe, and there are many uncertain factors in measurement, especially the measurement results are not objective and easy to falsify, GB21861-2014 " "Motor Vehicle Safety Technical Inspection Items and Methods" clearly stipulates that each motor vehicle safety technology inspection station must use a computer-controlled "vehicle external dimension measuring instrument" that automatically measures the vehicle external dimension to measure and record the external dimension data of motor vehicles and communicate with them. The original data of the vehicle's external dimensions are automatically compared and judged to strengthen the management and supervision of the vehicle from the root

However, the existing vehicle profile measurement methods are not advanced enough, resulting in large actual differences in the measured data
