The ZYA-RS100P fixed vertical motor vehicle exhaust remote sensing detection system is a multi lane exhaust remote sensing detection system specifically designed for urban main roads. By using spectral analysis technology to detect the concentrations of CO, CO2, HC, and NO in automobile exhaust, as well as the opacity and light absorption coefficient, the emission values of any vehicle passing through the road (including gasoline vehicles, diesel vehicles, and natural gas vehicles) can be analyzed. This system can measure the exhaust emissions of motor vehicles at the moment when the car passes by, and can simultaneously capture the license plate, model, body color, speed, acceleration, VSP and meteorological information of the car. Combined with the platform's data statistical analysis function, it can objectively reflect the emission information of motor vehicle exhaust. With the analysis of big data, targeted regulations for motor vehicle exhaust emissions can be formulated to reduce the pollution of motor vehicle exhaust to the atmosphere and promote the improvement of air quality.
