Design of Automated Medicine-Liquid Proportioning System Based on Spectral Analysis

The medicine-liquid ratio is an important part of various industries such as medicine and has important applications in the field of medical research. However, the traditional drug-liquid ratios are all artificial ratios, and the efficiency is low. In order to improve the efficiency of practical applications and reduce labor costs, this paper designs a set of automated chemical-liquid ratio system based on spectral analysis. This system takes an ethanol solution as an example. The spectrum analyzer is used to analyze the concentration of ethanol in the chemical solution. The PC reads the concentration information and controls the single-chip computer based on the information. The single-chip computer controls the peristaltic pump to perform the chemical solution ratio to obtain the appropriate concentration of the ethanol solution., Its accuracy is within ± 0.5%.
