Embodiment

[0056] By analyzing the test data of 16 chemical fingerprints of different types of traditional Chinese medicines, it is found that the unscreened map data files are about several hundred Kb, which greatly exceeds the capacity of the existing two-dimensional barcodes. However, after our data process processing, the amount of data has changed a lot. The following is the table of changes in the process of data processing, see Table 1.

[0057] Table 1 The change table of data string length and number of points in the process of data screening

[0058]

[0059] The above data screening process uses Ruby language programming. The length of the filtered data string ranges from 713 to 2323. Compared with the original data string length, the compression rate of the compressed string length is 0.23% to 0.64%, and the data point range is 110. ~337, the compression rate of the compressed data points is 1.12%-2.99% compared with the original data points.

[0060] After the data has b...

Abstract

The invention discloses a method for converting a chemical fingerprint chromatography into a two-dimensional code in traditional Chinese medicine quality tracing. Data files exported after detection of an instrument are converted into the same Excel formatted files ended with xls in a unified mode; the content of the data files is read, denoising processing is conducted, all kinds of unnecessary data are removed, and rounding is conducted on an absorbancy column; all feature point sets are found; one digit after the decimal point is reserved for a time column, and data deduplication is conducted with the time column as the benchmark; the final processed feature point data set is obtained; the final data set is converted into the two-dimensional code. The method solves the problem that the information amount of traditional Chinese medicine chemical fingerprint chromatography information is large, the traditional Chinese fingerprint chromatography can be successfully converted into the two-dimensional code through the algorithm, and the blank home and abroad is filled up.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine fingerprints, and in particular relates to a method for converting chemical fingerprints into two-dimensional codes in the quality tracing of traditional Chinese medicines. Background technique [0002] The production of traditional Chinese medicine raw materials to the sales of finished medicines is a multi-link and complex process. How to ensure the "safe, effective, stable and controllable" quality of the whole process of traditional Chinese medicine production is the key to the success of disease prevention and treatment. At present, the quality inspection of each link of traditional Chinese medicine production and distribution is relatively independent, and quality information cannot be shared with each other, which leads to the emergence of regulatory blind spots. How to trace the quality of traditional Chinese medicines and track the quality inspection information of tr...
