Scaner for decoding optically read label and opticaly read label for such device

摘要

The scanner for decoding optically read label comprises a unit for illuminating the settled passage zone of the label, an optical image generating unit of the settled zone with the installed label, creation of a binary card the elements of which correspond to luminances values of the light reflected from the label and excitation of each element of the generated optical image as well as a unit for decoding the binary card into electrical signals connected to the optical image generating unit outlet, creation of the binary card and excitation of each element, the decoding unit is made in the form of consequently joined units for two-dimensional restoration of the clock time synchronization signal on the optical label, a unit for detecting the geometric centres of the coded polygons for identification of their optical properties and the polygons decoding unit for encoding inversion.The optically read label comprises information coded polygons, the geometric centres of adjacent polygons are placed in the settled two-dimensional lattice tops, the polygons have at least one of two optical properties, the polygons have three, five and more sides, adjacently or partial adjacently placed, the label is executed with concentric rings in a zone separated from that one with polygons and each concentric ring has at least one of two optical properties in alternative sequence.The technical result consists in the fact that the invention allows to carry out high speed and precise operations of reading the information from the label in a great volume of labeled information as well as ensures loss protection because of mechanical or other injuries.
