Motor vehicle tail gas black smoke simulation system and method

Abstract

The invention is applicable to the technical field of tail gas monitoring, and provides a motor vehicle tail gas black smoke simulation system. The system comprises a meteorological acquisition instrument, a camera, a display device, a central processing unit and a ground camera, wherein the meteorological acquisition instrument and the camera are installed on a test road, the display device, thecentral processing unit and the ground camera are arranged on a tested vehicle, the meteorological acquisition instrument and the camera are communicated with the central processing unit through a communication device, the meteorological acquisition instrument is used for acquiring meteorological data in real time, and the camera is used for snapshotting the tested vehicle; and the display deviceand the ground camera are communicated with the central processing unit, the ground camera is used for acquiring picture characteristics of the ground, and the central processing unit generates a black smoke simulation image. The system has the beneficial effects that an augmented reality (AR) technology, an air fluid mechanics diffusion model and a high-frequency LED wide-view-angle display technology are combined, reusable, parameter-adjustable and pollution-free simulation of the motor vehicle tail gas black smoke is achieved, and an available metering calibration standard reference is provided for black smoke vehicle video snapshot equipment.

Description

technical field [0001] The invention relates to the technical field of tail gas monitoring, in particular to a simulation system and method for black smoke of motor vehicle tail gas. Background technique [0002] The emerging method of video capture of smoky vehicles uses cameras to record vehicles driving on the road, and uses mobile tracking and image AI recognition technology to identify and capture evidence of black smoke from vehicle exhaust, so as to achieve regulatory goals. At present, there is no effective metrological verification method for video capture equipment of smoky vehicles. The key lies in the lack of simulation devices suitable for camera capture of black smoke from motor vehicle exhaust. The existing simulation methods include the following: [0003] (1) Particle generator [0004] Through the principle of burning carbon black aerosol, use diffusion flame or premixed flame to generate real burning carbon black aerosol particles, the particle size range...
