LGH-07 Vehicle Exhaust Remote Sensing System

Release time:2021-05-13 10:45:58Read times: time


The vehicle exhaust remote sensing technology has gained increasing attention and trust in the market due to its speed, flexibility, and wide monitoring range. This system can monitor the exhaust of gasoline and diesel vehicles on the road, quickly identifying high-emission vehicles without interfering with normal vehicle operation. By integrating modern communication technology, the monitoring data can be organically connected with vehicle emission information and exhaust inspection data, enabling comprehensive management of vehicle emission data. This system provides support for management departments in vehicle pollution control and vehicle emission testing agencies, offering a complete set of tools for managing road exhaust pollution, capturing over-polluting vehicles, and monitoring specific vehicle emissions.

The vehicle exhaust remote sensing system is divided into two main categories: mobile and fixed. The fixed remote sensing system is installed on urban arterial roads, allowing for continuous measurement of passing vehicles, including horizontal and vertical fixed installations (gantry style). The mobile remote sensing system offers flexibility in determining measurement times and locations, effectively complementing fixed-point remote sensing measurements.

The vehicle exhaust remote sensing system mainly consists of a remote sensing host, high-definition speed detector, atmospheric parameter monitoring system, LED display, and vehicle exhaust remote sensing monitoring system control software.


Technical Features:

  • Utilizes proprietary TDLAS and DOAS monitoring technologies.
  • Simple operation, quick response, and minimal maintenance.
  • Narrowband radar speed detection with strong anti-interference capability and high measurement accuracy.
  • Vertical multi-point vehicle position recognition for precise capture of exhaust plume monitoring.
  • Integrated calibration system that allows simultaneous calibration of four components, supporting both automatic and manual calibration.
  • Highly integrated design that is compact and lightweight for efficient and rapid on-site deployment.
  • Integrated design for gasoline and diesel vehicles, enabling a single device to measure exhaust emissions from gasoline, diesel, and CNG-fueled vehicles.
