Problems solved by technology

[0008] However, in fact, this method is equivalent to setting only one VSP bin interval for the judgment interval of vehicle emission remote sensing data, and only a limit value is given, which does not take into account the characteristics of motor vehicle emissions changing with VSP, so it is easy to lead to misjudgment , not conducive to scientific and refined management
Since the VSP judgment interval of the validity of vehicle remote sensing data only selects a limited VSP range, the telemetry data beyond this range will not be used for subsequent evaluation, which leads to a large amount of remote sensing data being invalid

Embodiment 2

[0096] 1) According to the amount of ignition engine vehicle emission remote sensing test data and the need for refined management of different models, the types of ignition engine vehicles are divided into different categories, as shown in the attached figure 2 shown. Ignition engine vehicles can be classified as light, medium and heavy vehicles, which are further divided into light passenger cars, light trucks, medium passenger cars, medium trucks, heavy passenger vehicles and heavy goods vehicles. Ignition engines for heavy-duty vehicles generally have very few gasoline engines, and natural gas engines or alcohol fuel engines are common.

[0097] 2) According to the remote sensing test results of light passenger vehicle emissions in some ignition engine vehicles in Beijing, use big data statistical analysis methods for processing.

[0098] The VSP distribution of light passenger vehicles in ignition engine vehicles in Beijing is calculated by using the vehicle specific po...

Abstract

The invention discloses a spark ignition engine automobile exhaust emission remote sensing big data detection method and system. The system comprises an automobile exhaust emission measuring instrument, a main control computer, an information display instrument, an automobile driving state tester, a weather detector, a license plate camera and a motor vehicle emission monitoring platform. The automobile exhaust emission measuring instrument, the information display instrument, the automobile driving state tester, the weather monitor and the license plate camera are in communication connectionwith the main control computer, and the main control computer is connected with the motor vehicle emission monitoring platform through the Internet. The automobile exhaust pollutant content is collected through the system, the VSP of the automobile is divided into a plurality of Bin subareas, statistical analysis and evaluation are conducted on automobile emission according to different automobiletypes, and the high-emission automobile is judged.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust detection, and more specifically relates to a remote sensing big data detection method and system for ignition engine automobile exhaust emission. Background technique [0002] At present, the regular detection methods for the exhaust emissions of ignition engine vehicles in China mainly use the steady state method (ASM) or the simple transient state method (VMAS). When the detection conditions cannot be met, the ignition engine vehicle can use the double idle speed method, especially in the process of road inspection, due to the limitation of test equipment, the ignition engine vehicle generally uses the double idle speed method, although the equipment operation is very simple, but when testing The vehicle is stationary and not in the normal driving condition of the vehicle, so there will be a large deviation compared with the actual driving emission. In addition, the annual inspectio...
