System for detecting degree of automotive vehicle and environment-caused atmospheric pollution and operation method thereof

Abstract

The invention relates to a system for detecting a degree of automotive vehicle and environment-caused atmospheric pollution and an operation method thereof. The system comprises a data processing module, a PM2.5 processing module, a sulfur dioxide processing module, a wind speed and wind direction sensor, a lane occupation time processing module, an atmospheric sampling unit and vehicle sensor modules. In a sampling period, PM2.5 in air, sulfur dioxide, a wind speed, a wind direction and automotive vehicle inlet and outlet conditions in a detected zone are subjected to sampling; the sampling result is subjected to confluence analysis; a relationship curve of an automotive vehicle running state and an atmospheric pollution level are shown in a graph or a figure; and when the pollution index exceeds a set pollution index level threshold, an alarm is provided. Through the system, factual Influence produced by automotive vehicle tail gas, a wind direction and a wind speed on an atmospheric environment pollution level is quantificationally described; comprehensive reasons of pollution can be determined by a decision maker conveniently; and treatment processes aiming at the pollution are carried out.

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 detecting the air pollution degree of motor vehicles and the environment. 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. With the continuous deepening of people's understanding of the quality of the living environment, higher requirements are put forward for the quality of the atmospheric environment. The impact of pollution factors such as sulfur dioxide and PM2.5 produced by motor vehicle e...

Problems solved by technology

[0003] At present, domestic and foreign countries only pay attention to whether the atmosphere contains sulfur dioxide, PM2.5 and their quantity in the atmosphere monitoring. However, there is no real-time correlation with the exhaust gas emitted by the car at the current location and the monitoring value of sulfur dioxide and PM2.5 in the atmosphere.

It is impossible to quantitatively describe the impact of the number of cars passing through the road section per unit time and the exhaust emissions on the changes in sulfur dioxide and PM2.5 values

For the monitoring of wind speed and wind direction, there are high-precision wind direction and wind speed measurement equipment in the prior art, but they only monitor them, and there is no real-time correlation with air pollution and vehicle operating conditions, so it is impossible to see them intuitively. Combined with the impact of vehicle operation on air pollution, it is impossible to provide accurate data support for environmental policy decision makers to comprehensively consider, and thus it is impossible to accurately monitor vehicle operation through the degree of air pollution
