Real-time evaluation system of degree of atmospheric pollution caused by motor vehicle exhaust gas, and operation method thereof

Abstract

The invention relates to a real-time evaluation system of the degree of atmospheric pollution caused by motor vehicle exhaust gas, and an operation method thereof. The system is composed of a data processing module, a sulfur dioxide sampling processing module, a vehicle road occupation time processing module, an atmosphere sampling module, and a vehicle sensor module. With the vehicle sensor module and the vehicle road occupation time processing module, vehicle operation state is monitored, sampled, and analyzed. With the atmosphere sampling module and the sulfur dioxide sampling processing module, atmospheric pollution degree is sampled an analyzed. With the data processing module, a relationship curve of the vehicle operation state and the atmospheric pollution degree is displayed in a form of a chart or a table. Alarming is carried out upon the states exceeding a preset pollution index level threshold. With the system and method provided by the invention, an actual influence degree of exhaust gas emitted during vehicle operation to current atmospheric environment can be obtained quantitatively, such that a real cause of environment pollution can be conveniently obtained by a decision maker, and the pollution can be controlled and treated with targeted measures.

Description

technical field [0001] The invention belongs to the field of environmental science and technology, and in particular relates to a system and an operating method for real-time evaluating the degree of air pollution caused by motor vehicle exhaust. Background technique [0002] With the rapid development of the economy, the scale of the city continues to expand, the population continues to gather in the city, and the waste gas generated in the process of production, life and travel has increased significantly, resulting in increased air pollution in the city. The average residence time of gaseous pollutants in the atmosphere is as little as a few minutes, and as long as several decades or more than a hundred years. Air pollutants are generally divided into two categories: primary (primary) pollutants, which are directly discharged into the atmosphere from pollution sources; secondary (secondary) pollutants, which are produced by thermal or photochemical reactions of primary po...

AI Technical Summary

Problems solved by technology

[0004] In the above scheme, although the serious problem of tail gas pollution in some areas can be alleviated, the above technical scheme only focuses on the amount of vehicle exhaust emissions, and controls and selects the driving path of the vehicle completely according to the amount of vehicle exhaust emissions, without considering the operating status of the vehicle. Real-time correlation with the actual degree of environmental pollution, it is impossible to intuitively understand the degree of the actual impact of the exhaust gas generated by the vehicle operation process on the atmospheric environment, and it is impossible to accurately monitor the operation of the vehicle through the degree of air pollution
