Accompanying drawing explanation
Fig. 1 is for measuring the structural representation of the retroreflecting plate of motor-vehicle tail-gas in a preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, but not as a limitation of the invention.
Shown in Figure 1; embodiments provide a kind of retroreflecting plate for measuring motor-vehicle tail-gas; be laid in above road; its in mainly using infrared 3-6 micron waveband to measure the main pollutant consistence in motor-vehicle tail-gas; wherein; described reflecting plate forms primarily of substrate 1 and the protection muscle 3 be positioned at above substrate 1, and described substrate 1 surface isolation is formed multistage echo area 2 by described protection muscle 3, described echo area 2 is covered with the retroreflecting material of mid-infrared light.The wavelength of middle-infrared band is 3-5 microns, and belonging to is thermal infrared remote sensing.
Specifically, described protection muscle 3 is elongated and surperficial higher than described substrate 1, makes protection muscle 3 have certain difference in height with place, echo area 2 plane, like this, pressure wheel is when crossing described reflecting plate, and reflecting material can not be rolled, to extend the serviceable life of reflecting material; Described substrate 1 and the one-body molded employing metal material of protection muscle 3 are made and are preferably all adopted stainless steel to make; certainly described stainless steel is not limited to; be that retroreflecting plate must have enough intensity to the requirement of described retroreflecting sheet material matter, rolling for a long time of wheel can be stood.Wherein, between two adjacent protection muscle 3, interval is equal, makes echo area 2 area of formation substantially identical.
Principle of the present invention is, when light source is irradiated to the reflective tape on road surface above portal frame, due to the effect of retroreflecting, reflection ray can be got back to around light source substantially, to realize the measurement to whole width of roadway.
