The Research On Monitoring System Of Traditional Chinese Medicine Extraction Process Based On OPC

It is an important link that Chinese medicine extraction process in the production of traditional Chinese medicine.In the process of extraction of Chinese herbal medicine,each process parameters,operating parameters can lead to the different batches of extracts,directly affect the quality of traditional Chinese medicine.It not only provides the basis for production optimization,but also lays the foundation for the final realization of on-line quality control to real-time stored procedure parameters and operating parameters.But as is concerned about the current situation,first of all,it needs to improve the real-time data acquisition rate and implementation of production process data real-time open in order to realize online quality control,which can ensure the real-time analysis and optimization and achieve the control quality directly.So it is of great significance for realizing on-line quality control to research the technology of the fast data acquisition and data directly open and research oriented data open of traditional Chinese medicine extraction process monitoring technology,which has become the needs of the development of Chinese enterprises.Studying the monitoring technology for data opening through understanding the status of Chinese medicine extraction process monitoring system and the research status of OPC technology at home and abroad as well as the development trend.Mainly completes following work:determine the alcohol extraction process of measure and control scheme,completed the PLC system hardware design and configuration of traditional Chinese medicine alcohol extraction.It realize the construction of open data in the database by developing the OPC client.It was constructed that the monitoring system of Chinese traditional medicine extraction process based on OPC.It is determined about the method of the OPC data access.And it is realized the data communication between the management monitor layer and the control layer by developing the OPC client.Using Server SQL 2008 as the database,the PLC data was written to the SQL database through the OPC client.And researching the technology of data access based on C sharp and SQL Server 2008 as the database by developing the related program.To achieve the data real-time opening and transmission of the Chinese medicine alcohol extraction process production.Building the minimum Chinese medicine extraction process monitoring and control system based on C sharp.On the Microsoft Visual Studio 2010 development platform using C sharp programming language development of traditional Chinese medicine extraction process monitoring software,monitoring software and OPC client data transmission,real-time production data to the monitoring platform of efficient transmission and display,fast response and PLC monitoring platform.Implement the process view,parameter Settings,user management,data report,and other functions.
