Embodiment Construction

[0050] Such as figure 1 Shown is a flow chart of the reading steps of the one-dimensional barcode reading method of the present invention. Such as figure 2 Shown is a preferred embodiment of the reading engine for reading one-dimensional barcodes in the one-dimensional barcode reading method of the present invention. The one-dimensional barcode reading engine includes: an integrated housing 1 , a decoding circuit board 2 , and an image sensor circuit board 3 . The barcode decoding chip in the decoding board circuit board 2 can adopt the one-dimensional barcode decoding chip disclosed in Chinese patent document CN101840496B, and a circuit structure matching the chip is designed. The image sensor of the image sensor circuit board 3 adopts a strip CCD image sensor (Charge-coupled Device, charge-coupled device), and the CCD image sensor can adopt a strip CCD image sensor whose model is TCD1103GFG of Toshiba (Toshiba).

Abstract

A one-dimensional bar code recognition method comprises a recognition engine for recognizing one-dimensional bar codes, wherein the engine comprises an integrated shell, the integrated shell has an optical imagining area used for reflecting an imaging optical path, an image sensor circuit board is arranged on the side face of the integrated shell, a reflecting mirror is used for receiving the imaging optical path, the size of the bar code recognition engine is reduced, and thus the influence of spurious signals can be avoided, the signal-to-noise ratio of measurement is increased, and the stability of measurement is improved. Bonding pads are arranged on a decoding circuit board and the image sensor circuit board, and the decoding circuit board is fixedly connected with the image sensor circuit board through welding spots. When the decoding circuit board receives a trigger instruction for recognizing one-dimensional bar code, an image sensor acquires the image of the one-dimensional bar code and transmits the image to the decoding circuit board so that the image can be decoded and output.

Description

technical field [0001] The invention relates to an optical reading method, in particular to a one-dimensional barcode reading method. Background technique [0002] Barcode (referred to as barcode) can be divided into one-dimensional barcode and two-dimensional barcode. One-dimensional barcode is a mark composed of a set of regularly arranged bars, spaces and corresponding characters. "Bar" refers to the part with low reflectivity to light. "Void" refers to the part with high reflectivity to light, and the data composed of these bars and spaces expresses certain information. Two-dimensional barcode is a new generation of barcode technology that records data symbol information in a black and white rectangular matrix distributed in a plane (two-dimensional direction) according to certain rules; two-dimensional barcode can be divided into stacked two-dimensional barcode and Matrix 2D barcode. The stacked two-dimensional barcode is formed by stacking multiple short-cut one-dime...
