Laser barcode scanning platform supporting one-dimensional code and two-dimensional code recognition

Abstract

The invention provides a laser barcode scanning platform supporting one-dimensional code and two-dimensional code recognition, a working circuit and a working method. The laser barcode scanning platform comprises a PCB (printed circuit board), a main controller, a one-dimensional code scanning mechanism and a two-dimensional code scanning mechanism; the one-dimensional code scanning mechanism comprises a laser tube, a driving motor, a four-sided mirror and a reflecting mirror, wherein the laser tube is arranged on the PCB and is connected with the main controller through a laser scanning element control line; and the two-dimensional code scanning mechanism comprises a camera connected with main controller through a camera data bus. The camera of the laser barcode scanning platform of the invention can record a working range outside a transparent window through the transparent window of the laser barcode scanning platform; the main controller allocates the working flows of one-dimensional scanning decoding and two-dimensional scanning decoding according to a preset one-dimensional proportion and a preset two-dimensional proportion; and therefore, the recognition of one-dimensional codes and two-dimensional codes can be realized, and the recognition work of the one-dimensional codes and the two-dimensional codes can be seamlessly switched without stagnancy.

Description

technical field [0001] The invention belongs to the technical field of laser code scanning, and in particular relates to a laser barcode scanning platform supporting identification of one-dimensional codes and two-dimensional codes, its working circuit and its working method. Background technique [0002] Because the laser barcode scanning platform has the advantages of fast scanning speed and relatively strong scanning barcode compatibility, it is widely used in shopping malls and supermarket cash registers. However, the current laser barcode scanning platform can only scan paper one-dimensional barcodes, and cannot scan two-dimensional codes on mobile phone screens. With the progress of the times, it is more and more common for customers to use electronic payment methods such as Alipay and WeChat. Since the current laser barcode scanning platform does not support scanning the QR code of the mobile phone screen, merchants need to add another one that can scan the mobile pho...

AI Technical Summary

Problems solved by technology

[0004] The above technical solution has the following problems and disadvantages: for the laser scanning platform integrating the two-dimensional code recognition module, because the price of the two-dimensional code recognition module itself is not low, the overall cost is greatly increased, and the two-dimensional code recognition module is not small , which also leads to a larger overall product volume

Although the scanning platform assembled by the two-dimensional code recognition module is compatible with one-dimensional barcodes, its scanning efficiency for one-dimensional barcodes is much lower than that of laser barcode scanning platforms, which affects its practicability
