Embodiment 1

[0052] Such as figure 1 As shown, the present embodiment provides a system for quickly discovering a wide range of PM2.5 pollution trigger points, including a central processing unit 1 and M terminal devices 2, where M is an integer greater than 1.

[0053] 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 interval distance as about 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.

[0054] from figure 1 It can be obtained that each terminal device 2 includes: a storage unit 201, which stores t...

Embodiment 2

[0071] This embodiment is as a further improvement of embodiment 1, as described figure 1 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;

Abstract

The invention relates to a system for rapid discovery of an initiation point of large-area PM 2.5 pollution and an operation method thereof. The system is composed of a central processing unit and terminal units 1-M arranged on a pavement at a certain interval. The method comprises the following steps: coding the terminal units with 1 to M and storing corresponding positions in a terminal unit installation database of a central processing system in the form of ID serial numbers; synchronously reading sampling analysis results of each terminal unit by using the central processing system; determining whether pollution exceeds standards; and displaying an initiation point and an exceeding point on the central processing system. According to the invention, quantitative analysis of the degree of influence of motor vehicle exhaust on PM 2.5 in the atmospheric environment can be realized, and an initiation point which leads to exceeding of air environmental pollution indexes can be rapidly discovered.

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 PM2.5 pollution trigger point. Background technique [0002] With the continuous acceleration of social modernization, people have higher requirements for the quality of the atmospheric environment, among which PM2.5 is a new pollution source proposed in recent years, and it is also one of the main factors that form haze weather. The smog weather in many cities has seriously affected people's health, which has attracted great attention from governments at all levels. Among them, motor vehicle exhaust is the main cause of excessive PM2.5 values. How to quantitatively analyze the impact of motor vehicle exhaust on the degree of PM2.5 parameter exceeding the standard is the focus of attention. [0003] At present, the detection methods of urban air pollution in my country mainly i...
