Spectrum detection and correction device, method and drug authenticity judgment system

Abstract

The present invention provides a spectrum detection correction treatment apparatus, a drug authenticity judgment system containing the spectrum detection correction treatment apparatus, and a method for carrying out detection and correction treatment on a drug spectrum. The spectrum detection correction treatment apparatus comprises: a receiving part; a first acquiring and judging part; a first setting part; a second acquiring and judging part; a second setting part; a third acquiring and judging part; a third setting part; a judging part for judging a drug spectrum as a qualified spectrum when the drug spectrum is set as a first condition qualification spectrum, a second condition qualification spectrum and a third condition qualification spectrum; a searching acquiring part; a local maximum value acquiring part; a displacement deviation value calculation part for obtaining a displacement deviation value; a displacement correction curve fitting part for fitting the displacement deviation value to obtain a corresponding displacement correction curve; a displacement correction part for carrying out displacement value correction calculation on the qualified spectrum to obtain a displacement correction spectrum; and a final spectrum setting part for setting the displacement correction spectrum as the final spectrum.

Description

technical field [0001] The invention specifically relates to a spectrum detection and correction device, a spectrum detection and correction method, and a drug authenticity judgment system. Background technique [0002] Compared with traditional analysis and detection methods (such as chemical analysis, electrochemical analysis, chromatographic analysis, etc.), spectroscopy usually has the characteristics of fast, accurate, non-destructive, and microscopic analysis, and has broad application prospects in the field of pharmaceutical analysis. With the development of technology, miniaturized portable spectrometers are gradually popularized. The user-friendly operation interface allows non-professionals to operate and use the instrument. At the same time, some companies' instruments are equipped with spectral analysis software, which can analyze the spectra collected by users. judge. [0003] However, operators and users of spectrometers at the grassroots level are often non-p...

Problems solved by technology

Therefore, in the actual operation process, what kind of spectrum the sampler needs to collect to meet the requirements of subsequent analysis is sometimes unclear, which greatly wastes time, manpower and material resources

Although the current spectrum analysis software may include the function of removing abnormal spectra, these software only tell which are abnormal spectra, and usually cannot tell what causes the abnormality. For the setting of on-site test parameters for front-line sampling personnel And the guidance of the standardization of experimental operation is of little significance

In fact, good quality of spectra is an important prerequisite and guarantee for obtaining accurate and reliable analysis results. However, the current situation is that spectral analysis software generally focuses on the analysis of high-quality spectral data, and basically does not pay attention to whether the spectra to be analyzed have good quality or not. quality

[0004] In addition, the aging of the collection device (or collection system) and the errors between different types of collection devices will cause inconsistency in the collection results, thereby affecting the comparison results. If the qualified spectrum is directly compared with the standard drug spectrum, it is inevitable Misjudgment will occur
