[0018] like Figure 1 As shown, an intelligent electronic scale based on a multi-channel spectral chip capable of identifying the types of Chinese medicinal materials includes an electronic scale body 7. A multi-channel visible-infrared spectroscopy module 1 and a light source module 2 are located in the center of the electronic scale body 7. A main controller 4 and an LCD display 5 are located on the surface, and an electronic scale sensor 3 is located at the bottom. The multi-channel infrared spectroscopy module 1, light source module 2, and electronic scale sensor 3 are each connected to the main controller 4, which is connected to the LCD display 5.

[0019] The multi-channel visible-infrared spectrum module 1 comprises several channels of visible light and infrared spectrum modules. The multi-channel visible-infrared spectrum module 1 preferably utilizes the AS7265x chip from ams Semiconductor.

[0020] The wavelength of the light source module 2 matches the wavelength range of the multi-channel visible-infrared spectrum module 1 .

[0021] The wavelength range of the light source module 2 is between the visible light and the near infrared light wavelength range.

[0022] The light source module 2 is composed of one or several visible-near-infrared wide spectrum LED diodes, preferably Shenzhen Guohong visible-near-infrared wide spectrum LED.

[0023] The wavelength range of visible-near infrared wide spectrum LED diodes is 380~1050nm.

[0024] The main controller 4 is a separate single-chip processing unit.

[0025] Working principle: First, the diffuse reflectance multi-channel characteristic spectra of different types of Chinese medicinal materials 6 are collected and the data is stored in the memory of the main controller 4. Then, the spectral data of different types of Chinese medicinal materials 6 are identified and distinguished through the recognition algorithm, thereby displaying information such as the name and weight of the medicinal materials.

[0026] Workflow:

[0027] like Figure 2 As shown, the light source module 2 and the multi-channel visible-infrared spectroscopy module 1 constitute the data acquisition sensor. Light emitted by the light source module 2 is diffusely reflected by the surface of the Chinese medicinal material and then received by the centrally mounted multi-channel visible-infrared spectroscopy module 1. After receiving the diffusely reflected light signal, the multi-channel visible-infrared spectroscopy module 1 transmits the spectral data to the main controller 4 for data processing. The weight of the medicinal material is collected by the electronic scale sensor 3 and transmitted to the main controller 4. The final identification and quality data are then processed and displayed on the LCD display 5.

[0028] Before it is put into use, it is necessary to first establish a model through an algorithm. This utility model uses algorithms such as PCA-KNN and PLDA to establish the model. The specific steps are as follows:

[0029] First, the LED spectrum of the light source module 2 is calibrated with a reference whiteboard. Then, multi-channel spectral data of various types of Chinese medicinal materials 6 are collected. After the data is calibrated and normalized, it is processed by the main controller 4 for data dimension reduction. Then, a model is established and the data is saved using a pattern recognition algorithm. The sample spectral data is identified based on the diffuse reflectance spectral data model of the Chinese medicinal materials 6. Figure 3 As shown in the figure (two-dimensional distribution diagram of multi-channel feature data of different Chinese medicines after PCA dimensionality reduction), different Chinese medicinal materials 6 have distinguishable differences in the distribution diagram.

[0030] Then, the trained algorithm model is transplanted into the main controller 4, preferably an STM32 single-chip microcomputer. The data collected by the multi-channel visible-infrared spectrum module 1 is processed by the model algorithm of the main controller 4, and the final processed recognition results are displayed on the LCD display 5.

[0031] The present invention mainly uses this spectrum as data for identification and identifies various types of Chinese medicinal materials 6. This improves the accuracy of work in drug stores and medicinal material markets and improves efficiency.
