Problems solved by technology

This situation is acceptable for experimental research, but it will be very difficult or even impossible to carry out exhaust emission detection under real road conditions on major urban roads, to screen high-emission vehicles without affecting normal driving on the road.
[0003] The method proposed by the existing multi-lane exhaust telemetry patent has great application limitations, or cannot be practically applied
For example, (1) install a reflector or some kind of device in the iso

Embodiment Construction

[0018] The invention proposes a monitoring system for real-time remote measurement of the tail gas of vehicles running on one-way and two-way multi-lanes, which is placed on both sides and above the road. The invention uses video road condition recognition to recognize the driving position of multi-lane vehicles, and uses infrared absorption spectroscopy and ultraviolet differential absorption spectroscopy to automatically monitor pollutants CO, CO2, NO, NO2, HC and smoke in vehicle exhaust.

[0019] Such as figure 1 As shown, the multi-lane motor vehicle exhaust remote measurement device of the present invention is composed of a vehicle road condition recognition unit, a license plate recording unit, a vehicle speed and acceleration measurement unit, an infrared and ultraviolet absorption spectroscopy pollution gas monitoring unit, and a control and data analysis and processing unit.

[0020] 1. The multi-lane vehicle road condition recognition unit is composed of a road cond...

Abstract

A multilane motor vehicle exhaust remote measuring device comprises a vehicle road condition recognizing unit, a license plate recording unit, a vehicle velocity and acceleration measuring unit, a polluted gas monitoring unit by using infrared and ultraviolet absorption spectrometry and a control and data analysis/processing unit. The device can obtain the real-time condition of vehicle driving on one-way or two-way multilane pavement, accurately obtain various exhaust concentrations, velocity, acceleration and license plate number when only one vehicle drives on multiple lanes in a short time and complete preliminary exhaust analysis and license plate obtainment when a plurality of vehicles drive on multiple lanes simultaneously.

Description

technical field [0001] The invention relates to a multi-lane motor vehicle tail gas telemetry device, which belongs to the field of environmental technology. Background technique [0002] The motor vehicle exhaust remote measurement system can complete the exhaust emission detection under the normal operation state of the vehicle. Compared with the exhaust emission detection methods of the idle speed method and the working condition method, it can better reflect the actual emission situation of the road surface. The motor vehicle exhaust remote measurement device needs to pass the detection beam (IR or (and) UV) through the exhaust gas mass, so the light source transmitter and receiver should be placed on both sides of the road, or the transmitter and receiver should be placed on the same side of the road , the light reflector is on the other side of the road. The device can measure the exhaust emission of vehicles passing the detection beam on a single-lane road, and corre...
