Two-dimensional code and automatic identification voice playing device using same

Abstract

The invention discloses a two-dimensional code. The code graphic symbol of the two-dimensional code is a rectangle and comprises n*n barcode units, and the rectangle is divided into an n*n matrix, wherein the barcode unit in the n-th row and the first line of the matrix is a reference identifier unit; and the rest barcode units are data units. Each barcode unit is represented by a graph which consists of a plurality of same round dots, wherein n is a natural number which is more than 1. The invention also discloses an automatic identification voice playing device using the two-dimensional code. The device comprises an optical sensor, a master control unit, a power supply, a memory, a playing device, keys and a universal serial bus (USB) interface. A user can listen to contents which are required to be read by reading two-dimensional code information in a printed product through the automatic identification voice playing device.

Description

technical field [0001] The invention relates to a code map and a device using the code map, in particular to a coding method of a two-dimensional code and an automatic recognition voice playback device using the two-dimensional code. Background technique [0002] With the development of science and information technology, there are more and more types of automatic identification technology. The development of automatic identification technology is mainly reflected in the improvement of data quality and input speed and the elimination of human interference. Among them, barcodes and magnetic cards are more prominent. , IC card and radio frequency identification. However, the two-dimensional barcode has obvious advantages in terms of cost of information carrier, information volume, confidentiality, anti-pollution and anti-interference, and standardization, and has a good prospect for promotion and application. Two-dimensional codes can be used in a wide range of fields, such a...

AI Technical Summary

Problems solved by technology

[0003] At present, the two-dimensional code coding method on the market is generally clear code, and the clear code can only appear in the blank space of the layout, usually in the form of a single code, which has a certain impact on the beauty of the layout; and the printing area of ​​the clear code is large, which is difficult for reading. The device has higher requirements

Another encoding method is a secret code, but the current existing encoding methods are mostly arranged in solid dots. Due to the dense number of dots, the visibility of the dots after printing is low, and the code volume of a single two-dimensional code is small, and the information that can be stored less amount
