Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission monitoring, and in particular to a device for monitoring traffic carbon emissions. Background Art

[0002] With the gradual change of climate in modern society, in order to protect the environment and reduce the impact of the greenhouse effect, people have begun to pay more attention to the carbon emissions of various vehicles on road traffic, in order to reduce the damage caused to the environment by carbon dioxide emitted during vehicle driving.

[0003] The commonly used method for monitoring carbon emissions in road traffic is to install carbon dioxide sensors on both sides of the road. After a car passes by one side of the carbon dioxide sensor, the carbon emissions in the car's exhaust are detected, which plays a role in monitoring the car's carbon emissions. However, this method does not have the function of collecting exhaust gas when detecting the exhaust gas of the car. Due to environmental influences, the exhaust gas will quickly dissipate into the environment after being emitted from the car. Therefore, the accuracy of using carbon dioxide sensors to detect carbon emissions in car exhaust is difficult to control. Another method for monitoring carbon emissions of cars is the non-dispersive infrared detection method. This monitoring method is to set up a non-dispersive infrared emitting device on one side of the road and then set up an infrared sensing detection device on the other side of the road. By detecting the change in the intensity wavelength of the infrared light after passing through the exhaust gas, the carbon emissions in the car exhaust are judged. This method is more accurate, but because the speed of the car is not consistent and the exhaust gas is quickly dispersed after being discharged, it is easy to make it difficult for the non-dispersive infrared monitoring method to detect the carbon emissions of the exhaust gas accurately enough.
