Abstract

The invention discloses a method for correcting motor vehicle exhaust telemetry results, which comprises the following steps: collecting basic information of motor vehicles, motor vehicle exhaust telemetry data, and environmental variables around the installation point of the telemetry equipment by using a vertical remote sensing detection device for motor vehicle exhaust, and acquiring Information related to the annual inspection of motor vehicles; establish a data set of motor vehicle exhaust emissions, and preprocess the collected data; use the random forest model to train the correction model of the remote sensing detection results of motor vehicle exhaust, and realize the real-time online detection of remote sensing detection results of motor vehicle exhaust fix.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a method for correcting motor vehicle exhaust remote measurement results. Background technique [0002] With the rapid development of the national economy and the improvement of the people's economic level, the number of motor vehicles has increased year by year. The problem of air pollution in my country is becoming more and more serious. Severe haze occurs from time to time, especially in the Beijing-Tianjin-Hebei region. Motor vehicle exhaust is one of the main sources of urban air pollution, and its negative effects mainly include: causing human respiratory diseases, high levels of surface ozone, aggravating the urban heat island effect, and producing photochemical smog. Therefore, my country urgently needs to detect the concentration of motor vehicle exhaust pollutants in order to reduce and control motor vehicle exhaust emissions. [0003] Remote sensing te...
