Embodiment

[0044] Example: Generate a two-dimensional barcode. This barcode is generated by the title of the famous bestseller "How Steel Was Tempered". Some information control settings are made on this barcode. The version number is 1, all terminals are available, and the search type is set to all available networks and built-in Database, the keyword is "how steel is tempered", the return type is all types, and the return sort is set to automatic. Its encoding generation information is as follows:

[0045] 01111111111100000000001111111111

[0046] 00000000101010011000101011000111

[0047] 000000000000000000000000000000001

[0048] 00000000111111111111111111111010

[0049] 00000000000011111111111111111111

[0050] 00000000000011111111111111110011

[0051] 00000001000001000011111111111111

[0052] This 2D barcode can be printed on the back of the book. Through information collection on the Internet of Things, you can get:

Abstract

The invention discloses an Internet-of-things-based two-dimensional barcode information capacity expanding and encoding scheme, which belongs to the fields of two-dimensional barcodes and the Internet of things, solves problems on the authority in information capacity expansion in the Internet of things, the capacity-expanded information security and the capacity-expanded information control of two-dimensional barcodes, and can be applied to logistics control, commodity advertising and anti-counterfeiting and the like.

Description

technical field [0001] The invention is applied to the fields of two-dimensional barcodes and the Internet of Things. Background technique [0002] Two-Dimensional Barcode (Two-Dimensonal BarCode) records data symbol information with a specific geometric figure distributed on a plane (two-dimensional direction) according to certain rules; The logic-based concept of "0" and "1" bit stream uses several geometric shapes corresponding to binary to represent text and numerical information, which can be automatically read by image input equipment or photoelectric scanning equipment to realize automatic processing of information. [0003] Coding capacity (coding capacity) is the maximum number of characters that can be represented in the barcode character set. Each code system has a certain encoding capacity, which is determined by its encoding method. The encoding capacity limits the maximum number of characters that can be contained in the barcode character set. [0004] At pr...
