Problems solved by technology
Although this technical solution can accurately obtain the pollution emissions of motor vehicles, it does not correlate the operating status of motor vehicles with the actual pollution level of PM2.5 in the atmosphere in real time
At home and abroad, they only pay attention to whether there is PM2.5 in the atmosphere and the amount in the atmosphere monitoring. There is also no real-time correlation with the exhaust gas emitted by motor vehicles at the current location and the monitoring value of PM2.5 in the atmosphere at the current time period, which cannot be quantified. Describe the influence of motor vehicle exhaust on the change of PM2.5 value

Embodiment Construction
[0040] This embodiment provides a system for quickly discovering the impact of motor vehicles on atmospheric PM2.5, its principle block diagram is as follows figure 1 As shown, it includes a data processing module 1, a PM2.5 processing module 3, a vehicle occupancy road time processing module 4, a PM2.5 sampling module 5 and a vehicle sensor module 6.
[0041] The vehicle sensor module 6 is arranged at the vehicle entrance and vehicle exit of the road section to be inspected, and detects the vehicles entering and exiting in real time.
[0042] The PM2.5 sampling module 5 is set at the inspected road section and collects atmospheric samples within the inspected road section.
[0043] Vehicle occupied road time processing module 4, every time T s Receive the signal of entering the vehicle and the signal of exiting the vehicle detected by the vehicle sensor module 6 once, and obtain at time T s The number of vehicles on the inspected road section and the time t that the vehicle...

The invention relates to a system rapidly detecting the influence of motor vehicle to atmospheric PM2.5, and an operation method thereof. The system is composed of a data processing module, a PM2.5 processing module, a vehicle road occupation time processing module, a PM2.5 sampling module, and a vehicle sensor module. Monitoring and sampling analysis are carried out upon vehicle operation state through the vehicle sensor module and the vehicle road occupation time processing module; Atmospheric pollution degree is sampled and analyzed through the PM2.5 sampling module and the PM2.5 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 by the data processing module, and alarming is carried out when a state exceeding a preset pollution index level is detected. With the system and method provided by the invention, the influence degree of PM2.5 in exhaust gas emitted during motor vehicle operation upon a current atmosphere actual PM2.5 content value can be quantitatively obtained. Therefore, a real cause of exceeded atmospheric PM2.5 content can be obtained by a decision maker, and atmospheric PM2.5 content exceeding 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 for quickly discovering the influence of motor vehicles on atmospheric PM2.5 and an operating method thereof. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important effect on air quality and visibility. Impact. Compared with coarser atmospheric particulate matter, PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, has a long residence time in the atmosphere, and has a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment. Meteorologists and medical experts believe that hazy weather caused by fine par...
