China Commodity Coding Center Hanxin Code Innovative Technology

The national “Tenth Five-Year Plan” major scientific and technological project undertaken by the China Article Coding Center— “Two-dimensional Barcode New Code System Development and Research on Key Technical Standards” has achieved breakthrough results, and China has a new type of two-dimensional bar code with completely independent intellectual property rights— Hanxin Code was born in the land of China at the end of 2005. Hanxin Code fills the gap in China where there is no independent intellectual property technology in the application of two-dimensional bar code system standards. This major breakthrough technology in the field of automatic identification technology was officially promulgated as a national standard on August 23, 2007, and the implementation date was February 1, 2008.

Hanxin Code has a strong lineup of industrial chains. From the beginning of the research, the article coding center organized the entire industry to research and develop the QR code, and gave up the right to earn all patents. It fully disclosed and supported manufacturers to apply Hanxin code technology. . As a result, Hanxin Code has many well-known enterprises to participate in the support, and manufacturers such as Weishen, Yirui Technology, US Welling, American Symbol and so on have formed a full range of products, laying a foundation for the promotion and popularization of Hanxin Code.

As early as 2003, Yirui Technology began preparation work for China's new code system project. In 2005, Yirui Technology cooperated with the National Article Coding Center to undertake the design and development of Hanxin Code. Through the analysis of a large number of models, a series of new technologies such as brand-new two-dimensional code positioning symbols and corrected graphics have been innovatively established, which has laid the technical and theoretical foundation for Hanxin code to go to the world, and is based on the development results of Yirui Technology Codeview , Developed the core algorithm of Hanxin code encoding and decoding; in 2006, Yiri Technology developed the world's first QR code reading device including Hanxin code, mobile phone QR code reading engine, and more than 10 mobile phones The realization of Hanxin code recognition has laid a solid foundation for the mobile business application of Hanxin code; in 2007, Hanxin code was officially promulgated as China's national standard, and Hanxin code became the first two-dimensional code standard with independent intellectual property rights in China. Yirui Technology also won the 2006 Annual Special Contribution Award from the China Automatic Identification Association.

The birth of Hanxin Code has broken the commercial monopoly of foreign companies on the core technology of 2D barcode generation and reading, and has broad promotion for reducing the application cost of 2D barcode technology in China and promoting the application process of 2D barcode technology in China. Application prospects.

The technical characteristics and performance of Hanxin code

Outstanding performance, from the perspective of code system, the strongest code system in history, not only has a fast recognition speed, supports more than 2,000 Chinese characters, but the ability of Hanxin code to resist damage, distortion, and anti-fouling has reached the world's leading level .

In terms of Asian Chinese text performance, it has unique innate advantages. It best supports the GB18030 large character set, so that not only can Chinese characters be expressed with the highest efficiency in a two-dimensional code, but also supports China, Japan, South Korea and China. A few texts are mixed typesetting.

Hanxin code is a brand-new two-dimensional matrix code, which is led by the China Article Coding Center and organized by relevant units for cooperation and development. It has independent intellectual property rights. Compared with other two-dimensional barcodes in the world, it is more suitable for the representation of Chinese character information, and can accommodate more information.

1. High Chinese character representation ability and Chinese character compression efficiency: Chinese letter code supports 1.6 million Chinese character information characters specified in GB18030, and uses a 12-bit compression ratio, each symbol can represent 12 ~ 2174 Chinese character.

2. Large information capacity: With the support of printing precision, each square inch can represent up to 7929 numeric characters, 2174 Chinese characters, and 4350 English letters.

3. Wide coding range: Hanxin code can encode all digital information such as photos, fingerprints, palm prints, signatures, voices, and texts.

4. Support encryption technology: Hanxin code is the first bar code that reserves an encryption interface in the code system. It can be integrated with various encryption algorithms and cryptographic protocols, so it has strong security and anti-counterfeiting performance.

5. Strong anti-fouling and distortion capabilities: Hanxin codes have strong anti-fouling and distortion capabilities, can be attached to commonly used planes or barreled items, and can be read in the absence of two positioning marks

6. Strong error correction ability: Hanxin code adopts the world's advanced mathematical error correction theory, and uses the Reed-Solomon error correction algorithm commonly used in space information transmission, so that the error correction capability of Hanxin code can reach 30%.

7. Error correction capability for users to choose: Hanxin code provides four error correction levels, so that users can choose from 8%, 15%, 23% and 30% various error correction levels according to their needs, thus Has a high degree of adaptability.

8. Easy to manufacture and low cost: using existing dot matrix, laser, inkjet, thermal / thermal transfer, card machine and other printing technologies, you can print Chinese on paper, cards, PVC, or even metal surfaces Letter code. The added cost is only the cost of ink, which can really be called a "zero cost" technology.

9. The shape of the bar code symbol is variable: Hanxin code supports 84 versions, which can be selected by the user. The minimum code is only the size of the nail.

10. Beautiful appearance: Hanxin code has taken into account human visual acceptance at the beginning of design, so compared with the existing international two-dimensional bar code technology, Hanxin code has outstanding features in visual sense.

Development of Hanxin code reading equipment

In terms of technological innovation, in addition to participating in the research and development of Hanxin Code, Eretech also solved the software and hardware problems of the generation and reading system, and independently developed the first domestic professional QR code reading device RC532-130 Desktop II QR code barcode reader, RC322-30 pen type two-dimensional barcode reader. Currently, the supported mobile phone reading operating systems are: Symbian, Linux, WindowsMobile.

RC532 desktop reader is a fully automatic induction two-dimensional bar code reading device launched by Yirui Technology. The device itself can be turned on or off automatically according to the object being read. At the same time, it adopts the unique hardware frame system patented technology and cooperates with the 5th generation QR code reading engine of Yirui Technology, which reduces the cost of the device and improves the work efficiency of the product. , To achieve the highest cost performance.

RC322 handheld two-dimensional bar code reader is the first image-based on-line barcode reader in China. Due to the unique design concept, it is specifically designed for the field of commercial automatic identification, which greatly reduces the cost of equipment and supplements the Chinese market. Image-based online handheld 2D barcode reader blank.

These two devices involve technologies such as light, sound, electricity, and ergonomics, especially integrating image (pattern) recognition technology, barcode and two-dimensional codec technology, embedded application technology, and password security technology. Provides a high-value guarantee for the safety and use of equipment. It has broken the monopoly position of foreign products in the domestic market and achieved the highest cost performance.

From the research and development of code system to the development and production of reading equipment, it not only broke the long-term monopoly of foreign code system, but also laid a good technical foundation for the application and development of Hanxin. In addition to having confidence in the promotion and application of Hanxin Code, YIRI Technology has accumulated many years of rich experience and sufficient preparation. YIRI Technology is committed to pushing China's own two-dimensional code-HanXin Code to the world.
