Identification system of smoke intensity image of tail gas of diesel vehicle

Abstract

The invention relates to an identification system of a smoke intensity image of tail gas of a diesel vehicle. The identification system consists of a vehicle detection unit, a license plate identifying and processing unit, a vehicle velocity and acceleration measuring unit, a vehicle tail gas monitoring unit and a central data processing unit. The identification system provided by the invention can acquire the real-time condition of a vehicle running on the roadway, and accurately acquire tail gas smoke intensity level, velocity, acceleration and license plate number of the vehicle running on the roadway in a short time.

Description

technical field [0001] The invention relates to a diesel vehicle exhaust smoke image recognition system, which belongs to the field of environmental technology. Background technique [0002] Traditional diesel vehicle smoke measurement methods mainly include measurement with Ringelmann blackness telescope and smoke meter measurement. The Ringelmann blackness telescope adopts the binocular prism telescopic system, and the corresponding Ringelmann smoke concentration is made on the telescope dividing plate. Figure 1-5 Level gray scale block, fully transparent part is 0 level. The observer compares the smoke target with the gray gradient block of this level through the left eyepiece of the telescope, so as to determine the standard level of smoke blackness. The smoke meter is divided into a sampling part and a measuring part. The sampling part is that the sampling gas cylinder extracts a certain volume of flue gas in the exhaust pipe, and makes it pass through a certain area...

AI Technical Summary

Problems solved by technology

[0003] The above method can measure the smoke level of diesel vehicle exhaust to a certain extent, but it has great application limitations in practice, or it cannot be practically applied

For example, (1) Although the smoke level of diesel vehicle exhaust can be measured with the Ringelmann blackness telescope, it cannot record the blackness level of diesel vehicle exhaust and the relevant information of the vehicle; (2) The Ringelmann blackness telescope can measure the exhaust gas of diesel vehicles Must be measured manually

It is time-consuming and labor-intensive, and it is impossible for the traffic police to observe each vehicle with the Ringelmann blackness telescope for 24 hours; (3) The smoke meter can only be used to measure static diesel vehicles, but cannot measure driving vehicles
