Embodiment 1

[0031] refer to figure 1 , a certain original information, the information to be transmitted has a category attribute, and the information is composed of content fragments with different category attributes, and needs to be restored to the original information or other efficient processing through a two-dimensional barcode intermediary. The entire information exchange process is divided into two stages: pre-exchange and post-exchange.

[0032] First, establish a category table between different category attributes and numbers, and a common template table between different attribute information and template numbers;

[0033] Second, we will analyze the original information, decompose it into appropriate information fragments according to their properties, and separate them with separators; classify the information fragments, and then summarize these classifications, and number the categories of different properties, such as A, B, C, ... (this is just an example, not limited to...

Embodiment 2

[0045] refer to figure 2 , a coding device for implementing the method for transmitting information based on a two-dimensional barcode, comprising a two-dimensional barcode encoder 5, the information to be transmitted has category attributes, and the information is composed of content fragments with different category attributes; The encoding device described above also includes a classification table 1 corresponding to category attributes and numbers, an information fragment entry module 2, an attribute information module 3 for arranging the numbers in sequence according to the order in which the information fragments are entered, and an attribute information module for composing attribute information and each information fragment A preprogrammed information module 4 with a fixed-format character string, the output of the preprogrammed information module 4 is connected to a two-dimensional barcode encoder 5 .

[0046] The encoding device also includes a common template table...

Embodiment 4

[0051] An existing mobile phone needs to be transported from the manufacturer to the sales channel. The information systems of the manufacturer and the distributor are independent. In order to achieve efficient management of mobile phone logistics, the manufacturer and the distributor use two-dimensional barcodes to exchange information.

[0052] We know that the design of the mobile phone is very compact, and the place where the two-dimensional barcode can be pasted is limited, which requires the area of ​​the two-dimensional barcode to be small, and at the same time must ensure the resolution of the two-dimensional barcode, which requires the method of the present invention.

[0053] The specific information of the mobile phone is as follows:

[0054] Mobile phone model: V628

[0055] Manufacturer: Motorola (China) Co., Ltd.

[0056] Production date: March 20, 2005

[0057] Network access license number: 02-0010-042968

[0058] Mobile phone system: CDMA

Abstract

The invention relates to a method for transmitting information based on two-dimension bar code, wherein said information has type characters; and the inventive method comprises that (1) building the type list between different type character and serial number; (2) decomposing the exchange original information into information blocks, to be separated by separators, while each information block is arranged by their sequence in the original information; (3) numbering the different type characters, and arranging them by the sequence of information blocks in original information, to obtain the character information; (4) forming two-dimension bar code from character information and information blocks via the code method of two-dimension bar code; (5), reading out two-dimension bar code, to obtain the character information and information blocks; (6) reducing the character information into type information, while they are one-to-one relative. The invention can keep original character information, and effectively treat the content after exchange, while the two-dimension bar code has minimum size in same resolution.

Description

(1) Technical field [0001] The invention relates to a method for transmitting information through a two-dimensional barcode and its dedicated encoding device and decoding device. (2) Background technology [0002] If it is necessary to form a two-dimensional barcode for the information on the business card, write all the text information on the business card, and generate a two-dimensional barcode through the two-dimensional barcode encoder. For information with classification attributes such as business cards, if all the information is directly converted into a two-dimensional barcode, the disadvantages are: (1), the amount of information carried is large, and the size of the two-dimensional barcode is larger at the same resolution; (2) After the information is exchanged, attribute information and content information cannot be distinguished, and subsequent efficient processing of the content information cannot be performed. (3) Contents of the invention [0003] In order...
