Abstract

The invention relates to the field of traditional Chinese medicine quality tracing, in particular to a method and a device of conversion of a two-dimensional code. The method comprises following steps of: respectively obtaining DNA sequences and chemical fingerprint chromatography data of a traditional Chinese medicine; screening out chemical fingerprint chromatography data satisfying a preset rule form the chemical fingerprint chromatography data, carrying out shaping processing on the screened-out chemical fingerprint chromatography data, and according to the size of the chemical fingerprint chromatography data subjected to the shaping processing, combining the chemical fingerprint chromatography data subjected to the shaping processing into an array storing required smallest byte size; processing the DNA sequences according to a first preset compression algorithm, and combining the processed DNA sequences and the combined chemical fingerprint chromatography data according to a set format; and converting the combined DNA sequences and the chemical fingerprint chromatography data into a two-dimensional code. Therefore, a problem of large amount of information of traditional Chinese medicines is solved; compression rate is improved; and the DNA sequences and the chemical fingerprint chromatography data are successfully converted into the two-dimensional code.

Description

technical field [0001] The invention relates to the field of quality traceability of traditional Chinese medicines, in particular to a method and device for converting two-dimensional codes. Background technique [0002] The quality and safety of traditional Chinese medicine are directly related to the development of traditional Chinese medicine, and have been paid more and more attention by all walks of life. It is necessary to establish a practical system to ensure it. Among them, it is a difficult problem to be solved urgently to carry out quality inspection on the production and circulation of traditional Chinese medicine and to establish a perfect quality traceability system of traditional Chinese medicine. [0003] At present, the DNA sequence of traditional Chinese medicine is generally used to identify its authenticity, and the chemical fingerprint is used to evaluate the quality of medicinal materials. [0004] Barcode technology is an important technical means of ...
