Embodiment 1

[0053] like figure 1 As shown, this embodiment provides a system for quickly discovering trigger points of large-scale pollution in the atmospheric environment, including a central processing unit 1 and M terminal devices 2, where M is an integer greater than 1.

[0054] Each terminal device 2 has a specific ID number, and is distributed and arranged on the inspected road section according to a certain interval distance. When the terminal device 2 is actually installed, the interval distance can be reasonably selected according to different situations in the city. In this embodiment Select the separation distance as 500 meters. Each of the terminal devices 2 has its own working clock. In order to ensure that all the terminal devices can work completely synchronously, the clock module 103 is used to control the working clocks of all the terminal devices 2 to be consistent.

[0055] from figure 1 It can be obtained that each of the terminal devices 2 includes: a storage unit 2...

Embodiment 2

[0072] This embodiment is as a further improvement of embodiment 1, as described Figure 4 The shown terminal device 2 also includes a vehicle sensor module 204, a vehicle occupied road time processing module 205, and a data integration unit 206;

[0073] The vehicle sensor module 204 is arranged at the vehicle entrance and the vehicle exit of the road section to be detected, and detects the vehicles entering and exiting in real time; The signal of entering the vehicle and the signal of exiting the vehicle detected by the vehicle sensor module 204 can be obtained at time T s The number of vehicles on the inspected road section and the time t that the vehicles occupy the road ci , where i is an integer and 1≤i≤N, Ts=T / N, N is an integer greater than 1; and the total time of vehicles occupying the road in the sampling period T is obtained Wherein said sampling cycle T can be selected according to the actual situation, such as 1 minute, two minutes etc., can select T in the pr...

Abstract

The invention relates to a system for rapid discovering of a large-range pollution initiation point of atmospheric environment, and an operation method thereof The system consists of a center processing unit and terminal devices 1-M distributing on a road surface at regular intervals. The terminal devices are coded from 1 to M, and the corresponding position is stored in a terminal device installation database of the center processing unit in an ID number form; sampling analysis results of each terminal devices are read simultaneously by the center processing unit, whether pollution is over standard is determined, and further the pollution initial point and standard-exceeding points are displayed in the center processing unit. The system not only can help to quantitatively analyze the influence degree of motor vehicles to the atmospheric environment, but also can help to rapidly discover the initial point causing standard exceeding of a pollution index of the atmospheric environment.

Description

technical field [0001] The invention belongs to the field of environmental science and technology, and in particular relates to a system and an operation method for quickly discovering a large-scale pollution trigger point of the atmospheric 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. Air pollution sources refer to sources that emit (or generate) air pollutants. According to the cause of production, it can be divided into: ① Natural source, the source of pollutants produced by natural processes. It includes harmful gases and dust produc...
