The Research On Monitoring System Of Traditional Chinese Medicine Extraction Process For Informatization

Traditional Chinese medicine extraction is directly related to the quality of traditional Chinese medicine products, and it is the most complex and critical part of the production process. With the implementation of the new GMP in 2010, put forward higher requirements for traditional Chinese medicine extraction technology, equipment and automatic control system. However, due to the complexity of Chinese medicine and the new requirements for quality control of traditional Chinese medicine, it is still the difficulty of process monitoring systems research of traditional Chinese medicine extraction to study the relationship between process parameters of traditional Chinese medicine extraction and product quality. As a direct indicator can not be on-line measured, by implementing the data information system of the production process, and studying the relationship between process parameters and quality indicators, to establish the relationship model between process parameters of traditional Chinese medicine extraction and product quality indicators, it is an effective way to achieve quality indicators of intelligent detection to indirect access to product quality indicators. Moreover, through the established relationship model, it can also control the appropriate process parameters, and ultimately achieve quality control.Therefore, it is necessary to establish a networked and open database to make a research on the monitoring system of traditional Chinese medicine extraction process for informatization, for achieving openness and sharing of production process data; study the established relationship between process parameters and quality indicators, to guide and control the production process, and ultimately achieve the purpose of quality control; build a networked monitoring system to achieve data information and resource sharing, meet the proposed requirements of the new GMP, and lay the foundation for the integration of comprehensive management and control of traditional Chinese medicine enterprises.This topic chooses the water extraction process of traditional Chinese medicine as a research object. By understanding the extraction and concentration process of traditional Chinese medicine, analyze the key parameters affecting the production process, determine the plan of system detection and control, and construct the framework of the monitoring system of traditional Chinese medicine extraction process for informatization. Meanwhile, carry out the design and development of PLC control system and monitoring software. It has the functions of real-time and remote monitoring of production process, user management, alarm management, report management, etc. The system can implement the query and storage of production process data and its procedure can be traced back. It has used industrial Ethernet communication protocol for communication between monitoring & management layer and control layer to provide the network interface for achieving enterprise data sharing. On the basis of them, make the research on database technology and information process technology, implement the creation of external SQL database and data openness, and store the production process class data of traditional Chinese medicine production process; at the same time, do the exploratory research on the relationship between process parameters of traditional Chinese medicine extraction and extraction rate. And according to statistical control theory, fit the regression equation of the extraction rate and process parameters. Finally, design and develop the information management platform for informatization in C# for the analysis of process data.The system is easy to use, with the friendly interface, run stable, and is able to meet the requirements of GMP.
