Method of calculating road motor vehicle emission based on air quality monitor equipment

Abstract

The invention provides a method of calculating road motor vehicle emission based on air quality monitor equipment. The method is characterized by comprising following steps of: installing the air quality monitor equipment beside a road so as to acquire air pollutant concentration data; installing meteorological equipment beside the air quality monitor equipment so as to acquire wind speed and winddirection data; acquiring a relationship between the air quality monitor equipment and the road position; and calculating road motor vehicle emission based on the monitor position, pollutant concentration data and wind direction and wind speed data. The method has the beneficial effects that the road motor vehicle emission is directly calculated through the monitor data of the air quality monitorequipment beside the road. The method is simple, can be further used for evaluating emission ratios of different road sections, and optimizes motor vehicle emission management.

Description

technical field [0001] The invention relates to the field of urban environment monitoring, in particular to a method for monitoring exhaust emissions of motor vehicles on urban roads. Background technique [0002] The main pollutants of motor vehicle exhaust are carbon monoxide (CO), nitrogen oxides (NO X ), hydrocarbons (HC), inhalable particulate matter, etc. NO X Volatile organic compounds (VOCs) are important hydrocarbons in motor vehicle exhaust pollution. Motor vehicle exhaust not only directly endangers human health, but also has a profound impact on the environment in which human beings live. [0003] In recent years, under the impetus of the "Ten Measures for the Atmosphere", my country's air pollution prevention and control has achieved remarkable results. Such as Beijing-Tianjin-Hebei PM 2.5 The decline rate reached 39.6%, and PM in 338 cities above the prefecture level across the country 10 The decline rate reached 22.7%. The mission objectives of the "T...

[0012] Exhaust gas telemetry equipment monitoring, this method can achieve continuous monitoring, but the monitoring cost is high, and the accuracy change will also vary greatly based on the traffic flow; based on the indirect monitoring of the on-board diagnostic system (OBD) terminal, it can be based on NO X However, this method also has errors in actual vehicle operation, and it is unlikely to realize online monitoring in all models, especially in private cars.
