Research On The Intelligent Control System For The Extraction Of Chinese Traditional Medicine (CTM)

This project is supported by State Development Planning Commission, and the Science-Tech Tackle Key Project of HaYao CiHang Pharmaceutical Co, Ltd..This paper is focused on the research of the intelligent control system of the extraction of Chinese Traditional Medicine(CTM), which includes the analysis and research of the mechanism of CTM's extraction , comparison and research of special valves and special industrial sensors used in the extraction of CTM, design of the control method and intelligent automatic equipment used in CTM's extraction.Firstly, this paper analyzes the working principle of CTM's extraction briefly, compares various methods of CTM's extraction, analyzes and compares the special valves and special industrial sensors used in the extraction of CTM.Some advanced control theories are introduced in this paper. Through Using intelligent control technology, such as neural network soft measures, fuzzy control, advanced sensor and network technique, A three-level control system is built. It includes integrated level, decision level, and execution level to control the main equipment evaporator. Simulation analysis results show that the control system can raise the integral performance of controller and strengthen the system's stability.On the bases of theoretical research, a multilevel control system is developed, which is composed of industry control computer, PLC and high-quality periphery modules. The software system that based on the database technology is very safe and convenient. The experimental and practical results show that the equipment can work steadily and reliably, and all the performance indexes have reached or exceeded the national criterion. The automatic control system also improves the liquid of the medicament and the cost is decreased.
