Embodiment Construction
[0042] Such as figure 1 As shown, the present invention relates to a method for classifying and monitoring motor vehicle exhaust. According to the characteristics that urban traffic pollution belongs to line source pollution, existing remote sensing detection equipment can be deployed on both sides of urban roads to detect motor vehicle exhaust in real time. At the same time, a variety of sensors are used to collect the characteristics of the currently inspected vehicle, so as to distinguish the type of the inspected vehicle, and then through the data detected by multiple remote sensing detection devices in a limited area, use fusion technology to estimate the concentration of pollutants in the current area Finally, the quality level of motor vehicle exhaust in a limited area (five levels of excellent, good, light pollution, moderate pollution, and heavy pollution) is obtained.
[0043] The specific method is as follows:

The invention relates to a method for classified monitoring of vehicle exhaust. On the basis of the characteristic that urban traffic pollution is line source pollution, conventional remote sensing and detection devices can be arranged at two sides of an urban road for real-time detection of vehicle exhaust; meanwhile, a plurality of sensors are utilized for acquiring the characteristics of a current to-be-detected vehicle so as to determine the type of the to-be-detected vehicle; based on data detected by a plurality of remote sensing and detection devices in a defined area are used, modeling and evaluation of the levels of pollutant concentrations in the current area are carried out by using fusion technology; and finally, the quality levels (including an excellent level, a good level, mild contamination, middle-level contamination and serious contamination) of vehicle exhaust in the defined area can be obtained.
Description
technical field [0001] The invention relates to problems related to the concentration of motor vehicle exhaust pollutants in the field of environmental detection, in particular to a method for classified monitoring of motor vehicle exhaust. Background technique [0002] Motorized vehicles provide people with tangible benefits such as speed and convenience. Yet cities have clearly paid a growing price for their reliance on motor vehicles. These costs include high road construction and maintenance costs, damage to economic development caused by road congestion, high levels of energy consumption and consequent economic and environmental costs, etc. In particular, the damage to human health and the environment has reached a very serious level. Among them, CO and NO are the most harmful to the environment and human health. X , HC and particulate matter, etc. Different types of vehicles, such as passenger cars, cars, and trucks, have different pollutant emissions due to their d...
