System and method utilizing video detection technique to monitor influence of motor vehicle on atmosphere

Abstract

The invention relates to a system and method utilizing a video detection technique to monitor influence of a motor vehicle on atmosphere. The system is composed of a data processing module, a sampling control module, a sulfur dioxide sample processing module, a vehicle occupancy road time processing module, a sulfur dioxide sampling module and a video detector, wherein the video detector and the vehicle occupancy road time processing module can carry out real-time monitoring and sampling analysis on operating states of vehicles, and the sulfur dioxide sampling module and the sulfur dioxide sampling module can sample and analyze atmospheric pollution degree; and the sampling control module can realize the synchronization control of the sulfur dioxide sampling module and the vehicle occupancy road time processing module, the data processing module utilizes a map or a table mode to display a relationship curve of an operating state of a motor vehicle and atmospheric pollution degree, and the operation state corresponding to the fact that a pollution index grade threshold value is exceeded is warned. The system provided by the invention can acquire practical incidence degree of tail gas when the motor vehicle operates on the atmospheric environment in a quantitive mode.

Description

technical field [0001] The invention belongs to the field of environmental science and technology, and in particular relates to a system and method for monitoring the influence of tail gas emitted by motor vehicles on the atmospheric environment by using video detection technology. 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. How to determine the degree of impact of various pollution sources on the atmospheric environment is the basis for decision makers to take corresponding measures. There are many factors that cause serious air pollution. People have reached a consensus that the exhaust gas produced by motor vehicles has seriously exceeded the air pollution standard. How to quantitatively analyze the act...

Problems solved by technology

But this method also has the following disadvantages: a. The coil must be directly buried in the driveway during installation or maintenance, so that the traffic will be temporarily blocked

b. The slit of the embedded coil softens the road surface and easily damages the road surface, especially at intersections with signal control, the damage may be more serious when the vehicle starts or brakes

c. The induction coil is easily affected by natural environments such as freezing, subsidence of the roadbed, and saline-alkali

d. The induction coil is limited by its own measurement principle. When the traffic is congested and the distance between vehicles is less than 3m, its detection accuracy will be greatly reduced, or even impossible to detect.

[0004] In addition, there is no real-time correlation between the current operating state of the vehicle and the actual degree of environmental pollution in the existing technology, and the actual impact of the exhaust gas emitted by the vehicle on the atmosphere cannot be obtained.

Especially in some places close to industrial pollution sources or near the airport, it is impossible to accurately judge whether the air pollution caused by the exhaust gas generated during the operation of automobiles or the pollution caused by other pollution sources
