Overall dimension measuring system of vehicle based on three projection plane theory

Abstract

The invention discloses an overall dimension measuring system of a vehicle based on a three projection plane theory. The system consists of a body length measuring device, a body width measuring device, a body height measuring device and a measurement and control system, wherein the measurement and control system is arranged in a control room of a detection device; the body length measurement device comprises three body length measurement units which are sequentially arranged in a vehicle forward direction and a length measurement laser range finder fixed on one of the body length measurement units, the three body length measurement units are fixed on a detection device mounting foundation through two support upright posts; the body width measurement device comprises a body width measurement unit which is fixed on the detection device mounting foundation through two support upright posts and is located in front of a tested vehicle; the body height measurement device comprises a body height measurement unit which is fixed on a support upright post of the body width measurement device and is vertical to the body height measurement unit.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a vehicle outline dimension measuring device used by public security vehicle management offices, vehicle inspection stations, expressway vehicle overload and limit inspection stations and other departments. Background technique [0002] At present, 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 and increasing the size of the vehicle. 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. According to the national standard GB 1589-2004 "Road Vehicle Outline Dimensions, Axle Load and Quality Limits", GB 7258-2004 "Technical Conditions for Motor Vehicle Operation Safety", and GB 21861-2008 "Motor Vehicle Safety Technic...
