Abstract

The invention discloses a motor vehicle exhaust detection device which comprises a light source, a gas detector, a retro-reflection device and a portal frame, wherein the portal frame comprises two supporting rods erected on two sides of the road and a transverse rod which is connected with the two supporting rods and is positioned above the road; the light source and the gas detector are arranged on the transverse rod of the portal frame; a reflection device is arranged on the surface of the road below the portal frame; and monitoring beams emitted by the light source are reflected into the detector by virtue of the reflection device on the road surface. According to the device disclosed by the invention, the problem that the traditional motor vehicle exhaust remote sensing instrument cannot deal with multilane exhaust monitoring is solved.

Description

technical field [0001] The invention belongs to the field of remote measurement of motor vehicle exhaust, in particular to a motor vehicle exhaust detection device. Background technique [0002] With the increase in the number of motor vehicles and the release of the policy of motor vehicle inspection every six years, it is particularly necessary to use remote sensing methods to detect motor vehicles on the road in real time. Moreover, the newly promulgated "Atmospheric Law" in 2015 clearly stipulates that real-time telemetry of motor vehicles can be carried out without affecting the driving of motor vehicles. [0003] Traditional motor vehicle exhaust remote detectors are installed horizontally, that is, the detection beam is parallel to the road surface. When the exhaust gas emitted by a motor vehicle cuts the detection beam, it will cause changes in the spectral structure of the detection beam, thereby obtaining the vehicle exhaust emission The composition and concentrat...
