Embodiment 1

[0056] Embodiment 1. Identification and grading of different bases of the original mountain silver flower and honeysuckle

[0057] 1.1 Preparation of potassium bromide blank sheet and sample sheet

[0058]Get Potassium Bromide (KBr, spectral purity 99.95% metals basis, anhydrous grade, powder, CAS No. 7758-02-3) 100 mg under an infrared oven lamp and put in an agate mortar to fully grind, move to a tableting mold, Pressed into a translucent sheet, that is, potassium bromide blank sheet.

[0059] Potassium bromide tableting method was used to prepare the sample. The sample was crushed by a ball mill and passed through a 100-mesh sieve. 2.5mg~3mg sample and 150mg potassium bromide were fully ground under an infrared oven lamp, and pressed into a sample sheet.

Abstract

The invention discloses a lonicerae flos identification method and equipment based on an infrared spectrum and a medium. The method comprises the following steps: establishing a lonicerae flos identification model through clustering analysis by using data sets A obtained after infrared spectrum pretreatment of different standard lonicerae flos samples and identification information of the data sets A; the preprocessing comprising the following steps: selecting a characteristic spectrum peak wave band from a one-dimensional spectrum of the infrared spectrum, and then carrying out vector normalization (SNV) standard normal variable transformation processing; inputting a corresponding data set B of a to-be-detected lonicerae flos sample into the identification model to obtain identification information of the to-be-detected lonicerae flos sample; the identification information comprising original information, and / or producing area information, and / or harvesting time information. The identification model established by the invention is good in accuracy of identifying the information of the lonicerae flos, and compared with a traditional method, the identification and classification efficiency and accuracy of the lonicerae flos are improved, and the method is suitable for identifying a large batch of lonicerae flos samples.

Description

technical field [0001] The present application relates to the field of computer technology, to infrared spectrum identification and grading technology of traditional Chinese medicinal materials, and in particular to an identification method, equipment and medium of Mountain Silver Flower based on infrared spectrum. Background technique [0002] Lonicerae Flos, also known as soil silver flower, southern silver flower, mountain honeysuckle or soil honeysuckle, comes from Lonicera macranthoides Hand.-Mazz., red gland Lonicera L.hypoglauca Miq., South China Dried buds or with first blooms of Lonicera L. confusa DC. or L. fulvotomentosa Hsu et S.C. Cheng. "Chinese Pharmacopoeia" records that it has the effect of clearing heat and detoxifying, and evacuating wind-heat, and can be used to treat carbuncles, sores, sore throat, erysipelas, heat-toxin bloody dysentery, wind-heat cold, febrile disease and fever. With the expansion of the planting area of ​​Shanyinhua, the original spe...
