Lane fixed motor vehicle exhaust remote sensing monitoring system

The system consists of a lane-fixed motor vehicle exhaust remote sensing monitoring system including:

Light source transmitter: built-in infrared and ultraviolet light sources.

Reflection system: placed in the auxiliary machine to receive the smoke group light source.

Exhaust gas analysis system: built-in infrared sensor, ultraviolet spectrometer.

It can fully identify and analyze various components such as CO, CO2, HC, NO, PM, etc.

Speed/acceleration detector: It can accurately calculate the driving status of the vehicle, thus providing a better basis for accurate determination of vehicle data.

Video capture system: high-definition camera, providing video basis for data analysis.

Weather meter: placed in the host computer, it can analyze the weather and transmit data to assist in exhaust gas analysis.

Control management system: placed in the host computer, setting system parameters and performing data processing and analysis.The system supports multi-point connections and can simultaneously connect transportation and environmental protection systems to implement data sharing and mutual transmission.
