Abstract
The present disclosure provides a method and system for detecting exhaust emissions of a vehicle equipped with an ignition engine based on big data of remote sensing. The system includes: a vehicle emission measuring instrument, a host computer, an information display instrument, a vehicle driving state tester, a weather monitor, a license plate camera and a vehicle emission monitoring platform. The vehicle emission measuring instrument, the information display instrument, the vehicle driving state tester, the weather monitor and the license plate camera communicate with the host computer. The host computer is connected to the vehicle emission monitoring platform via the Internet. The present disclosure acquires pollutant concentrations in the vehicle emissions through the detection system, divides a vehicle specific power (VSP) into multiple bins, performs statistical analysis and evaluation on the vehicle emissions according to different vehicle types, and determines high-emission vehicles.
