Motor vehicle exhaust smoke video identification system

Abstract

The invention discloses a motor vehicle exhaust smoke video identification system. The motor vehicle exhaust smoke video identification system comprises a video acquisition unit, a video data processing unit and a data center unit, wherein the video acquisition unit comprises an industrial network camera, the video data processing unit comprises an industrial control computer, and the industrial control computer comprises a vehicle tracking and processing module, a license plate identification and processing module, a vehicle speed measuring module and a vehicle exhaust monitoring module. The motor vehicle exhaust smoke video identification system has properties of simple structure, good robustness and no linkage equipment and has no equipment linkage coupling problem. Multi-lane monitoring, excessive vehicle discharge monitoring and license plate recording can be accomplished at one step, position recording is intelligible, and video recording is more persuasive. According to the motor vehicle exhaust smoke video identification system, the industrial network camera and the industrial control computer are only needed to realize processing on the lanes such as vehicle exhaust monitoring, license plate identification, smoke detection, vehicle velocity measurement, cost for equipment and mounting is greatly saved, and smoke detection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of environmental technology, and in particular relates to a video recognition system for motor vehicle exhaust smoke. Background technique [0002] Diesel locomotives have a large proportion of soot at medium and high loads with serious emissions, and usually appear as thick black smoke. Therefore, the detection of exhaust gas to characterize the content of soot is widely used in the evaluation of diesel engine emission pollution. At present, two types of testing instruments are generally used to measure the exhaust smoke of diesel engines: filter paper smoke meter and opacimeter. The measurement principle of the filter paper smoke meter is to accumulate the soot in a certain volume of exhaust gas on the filter paper, and measure the absorbance of the carbon particles of the blackened filter paper through a photoelectric detection instrument, which represents the exhaust smoke. The measurement principle of the opacim...

Problems solved by technology

However, this detection method can only be used for a single lane, and cannot be used for multiple lanes. If the vehicles are relatively close, the data cannot be obtained accurately, and the price is relatively expensive, so it cannot be widely used

[0004] The Chinese patent with publication number CN102737247A discloses a diesel vehicle exhaust smoke image recognition system, which uses vehicle images to identify the smoke of vehicle exhaust. This system includes multiple industrial computers, cameras and image acquisition cards, and the equipment is relatively complicated. The process is also more cumbersome
