Description

Technical Field

[0001] This invention relates to a data acquisition system for quality management of traditional Chinese medicine extraction, belonging to the field of quality control technology. Background Technology

[0002] Data acquisition is the core foundation of quality control, determining the stability of the extraction process in traditional Chinese medicine (TCM) and serving as a crucial prerequisite for ensuring the efficacy and safety of TCM. In the complex process of TCM extraction, several key process parameters, such as temperature, pressure, time, and proportions, interact. Deviations in data at any step can affect the overall extraction quality, making it difficult to guarantee consistent quality across different batches. Existing TCM extraction data acquisition technologies suffer from the following shortcomings: susceptibility to errors in manual recording, overly fragmented and independent hardware, limited software functionality, weak anti-interference capabilities, and insufficient analytical capabilities.
