Embodiment
The present invention is described in further detail in conjunction with drawings and examples.
Referring to Fig. 1, vehicular emission telemetering equipment of the invention is mainly comprised the following steps：Measure gasoline car discharge
CO, CO2、C3H8First device 1；Measure the NO of emission of diesel engine second device 2；Measure the NO of emission of diesel engine2With it is black
The 3rd device 3 of smoke particle device；Measure the speed measuring device 4 of motor vehicle speed；Number plate of vehicle identifying device 5；Environment weather is surveyed
Measure device 6；Number plate of vehicle and information display device 7；Master control device 8；Information carrying means 9；The first device, second device
With 3rd device be arranged on road above portal frame on same casing in, be located at the middle of the road, detection light source into
Waterfall type irradiating and detecting region 10 from top to bottom, to ensure that each motor vehicle passed through can be detected；And described first
Device, second device and 3rd device are designed to modularization, can be used alone, and also can be combined and use, and master control device is used
In control, the work of coordination modules.
Infrared rod type light source during first device is used, wave-length coverage covers 3-5 microns (μm).Referring to Fig. 2, by aspherical
Light is collimated into strip light spots 31 by cover in X-direction, is irradiated to detection zone 35, is then reflexed to receiving light path by detection zone
Go up and eventually arrive at detector 34.Receiving light path receives signal light by the way of concave mirror 32 and convex lens 33 are combined, recessed
The effect of face mirror is the area that increase receives light, so as to improve signal light intensity.Concave mirror both can be spherical mirror or
Aspherical mirror, such as off-axis paraboloidal mirror, ellipsoidal mirror.
As shown in figure 3, second device uses the mid-infrared laser light source from laser 44, because laser is with very good
Directive property, light beam have light beam it is thin, the characteristics of hot spot is small, so needing laser beam extension arriving whole detection zone
10.The present invention carries out spacescan using exposure subsystem 41 to laser, so as to realize the covering of whole detection zone.Receive light
Road equally receives signal light by the way of concave mirror 43 and convex lens 45 are combined, and it is reached detector 46.It should be noted
It is that in the present embodiment, light reflexes to polygon prism 41 from laser 44s by speculum 43.Its measuring principle is to be based on
Spectrum Absorption Principle, specific molecule has absorption to the light of specific wavelength.
Referring to Fig. 4, the light source of 3rd device is similar to first device, is all rod type light source 51, simply wavelength is different, its
For 410nm visible light source, receiving member also same first device, including detector 54 and convex lens 55,52.For black smoke particle
The part of measurement is mainly a high definition camera 57, when vehicle is by the way that before, high speed high definition camera constantly measures detection zone
As background, vehicle is after, and detection zone is affirmed different due to the influence of black smoke particle with original background.Pass through
Computer compares the difference of detection zone in two width pictures, so as to calculate the concentration of black smoke particle.Because detection zone may
Influenceed by sunshine, so needing additionally one secondary light source of increase, this light source and NO2For same light source.
In view of the influence of sunshine, narrow band filter slice 53,56 can be added before detector 54 and high definition camera 57.
