Stationary motor vehicle exhaust remote sensing monitoring system

The system detects the exhaust pollutants of motor vehicles running on the road in real time (CO, CO2, HC, NO and opaque smoke value, etc.), and monitors and records the speed, acceleration and license plate capture of passing motor vehicles in real time, providing professional data basis for pollutant emissions of motor vehicles on the road.

Key words: waste gas

Product Description

Stationary motor vehicle exhaust remote sensing monitoring system

Product introduction

The system detects the exhaust pollutants of motor vehicles running on the road in real time (CO, CO2, HC, NO and opaque smoke value, etc.), and monitors and records the speed, acceleration and license plate capture of passing motor vehicles in real time, providing professional data basis for pollutant emissions of motor vehicles on the road.

 

Working principle

(1) Rapid response non-dispersive infrared technology is used to measure CO, CO2 and HC. The above substance molecules all have characteristic absorption wavelengths in the infrared region. The absorption spectrum can be used as the "fingerprint" to identify different gas molecules, and the composition and concentration of molecules can be determined according to the wavelength and intensity of the absorption spectrum.

(2) Ultraviolet differential absorption spectroscopy is used to measure N0 and smoke. The type and concentration of trace gases in the atmosphere can be retrieved according to their characteristic absorption properties in the ultraviolet band. The measurement principle is based on the Beer-Lambert law. Due to the strong absorption of NO and molecules in the vehicle exhaust to the ultraviolet spectrum, the lamp is used as the ultraviolet light source, and the absorption spectrum line is used to determine the types and content of pollutants.
