Design of Intelligent Drug Chromatography Experiment Instrument Based on Machine Vision

Chromatographic method is a key step in the purification of natural Chinese herbal medicine. Because the traditional chromatographic experimental methods are time-consuming and laborious, an intelligent chromatographic experimental device based on machine vision is designed in this paper. The MCU of the device is STM32F103RCT6 embedded-microcontroller, the OV7725 image sensor is used to collect the liquid level data, and the WiFi module is used to establish wireless communication between MCU and Cloud server. After testing, it is found that the integration of machine vision, wireless intelligent control and automatic control into the chromatographic experiment device could realize the monitoring of the whole experimental process and the automatic processing of different stages of the experiment, which greatly reduced the time cost of the laboratory technician.
