    • 专利摘要:
    The invention refers to an optical-electronic system for the automatic identification of a retroreflective label attached to a car, container, industrial product, etc., in motion or at rest. To accomplish this end, two optical systems have been used, of which one emits light and the other receives light reflected by the label. The axes of the two systems are parallel and the lenses are tangent to each other, so that the angle between the incident and reflected beams on the retroreflective label are as small as possible.

    专利说明:

    The reflecting tag is placed at a distance of 2700-3300 mm from the rotating wheel at a height of ± 1250 mm relative to the level of the rotating wheel. After the spot 3 of the rays reaches the reflective surface of the Scotchlight type, it is reflected mainly in the direction of the falling light. Maximum intensity recorded within ± 0 ,. In the case of reflecting materials used, the change in intensity depending on the angle is not significant. In the case of newer materials, it is possible to obtain a decrease in the intensity of the example o by 5% with a deviation of the angle of incidence by 1 °. Since the distance between the axles of lenses 2 and 6 does not exceed 45 mm and the distance between the tag and the rotating wheel averages 3000 m, the angle between the incident beam C and the reflected beam P is about 50 minutes. Differences in the intensity of the reflected light for angles less than 1 °, relative to the theoretical axis, are very small. After the reflected beams are reflected by the mirror 3 of the rotating wheel 4, the light is received by the lens b and processed by an optical system consisting of lens 8 and diaphragm 7, which selects from the beam P the area corresponding to the width (fl2-5 mm on the reflective tag. The resulting light the flow is applied to a color of the light, a selector mirror 9 that transmits light and reflects blue.The two spots are filtered by a red bandpass filter and a blue bandpass filter, respectively, marked with numbers 10 and 12, and fed to, respectively, photomultipliers 11 and 1. Light signals are converted into electrical signals by photomultipliers, and these signals are logically processed by an electronic unit 14 to translate into a sequence of numbers constituting the code of the reflective tag. To prevent reflections due to the protective layer of the reflective tag from entering the systems and correction of the readings of tags located in the highest and samsad lower positions, the optical system has a slope of 12-15 relative to the rotating wheel, as a result of which the beam O leads to an angle of 12-15 with a plane perpendicular to the surface of the reflecting tag. An optical-electronic device for recognizing a retro-reflective tag. Eliminates additional reflections, facilitates the construction of the optical system, allows you to easily obtain the image of the reflective tag and higher energy efficiency by using lenses with relatively large apertures and more powerful light sources, and, linear, not point; nakgsha thread. Foeechula. 1. An optical electronic device for recognizing a retro-reflective tag containing a light source, a mirror rotating drum, a lens mounted between a color picker, a mirror and a diaphragm plate, two band-pass filters and a photomultiplier and an electronic processing unit, characterized in that In order to improve the accuracy of tag recognition, it is equipped with two lenses equidistant from the drum axis with parallel optical axes, with this one being located between the light source and: dimsy drum, and a friend between the drum and the diaphragm. 2. Device pop. 1, that is, that the angle between the incident beam and the reflected beam is 50 minutes, with a distance of 3000 mm from the axes of the lenses to where it is located and the tags. .
