A Research Of On-line Detection Of Chinese Traditional Medicine Cataplasma Viscosity

Plaster as one of the four traditional Chinese medicine has a long history and positive impact on the treatment of some diseases. This article develops a "sensor network technology based on intelligent shaping equipment of plaster.", which is based on Science and Technology Project," Chinese new plaster systems and evaluation of key technologies". This will improve the patented technology with independent intellectual property rights and make significant innovation of traditional Chinese medicine in China. It will improve the progress of production technology and the establishment of technical standards. It will further enhance technology and product standards of plaster system, and promote the standardization and modernization of Chinese medicine.This study mainly solves the problem of real-time online plaster viscosity's detection according to the requirements of project .We have done lots of research about Chinese plaster viscosity of online detection including viscosity characteristics of plaster, the traditional methods of measuring liquid's viscosity, the requirements of project, etc. Then we design a set of equipment which can measure the plaster's viscosity and control with feedback. In terms of hardware, the equipment consists of motor, PC, PLC and sensors and so on .In terms of software, PLC acquires data from sensor, PC computes and send data to PLC by communication, and then PLC control the viscosity according to the default parameter. Finally, we get data by the device, build model by least squares method and BP neural network model, and design the fitting and calculation process. And then the model predictions were compared. By comparison, BP neural network is more consistent with precision of plaster's viscosity. Besides, it is convenient to improve the plaster's viscosity accuracy in the future. And BP neural network prediction algorithm program is completed by VC++,MATLAB and database.The system can accurately get the on line detection viscosity and timely feedback to the PLC and PC for processing and real-time controlling to ensure the quality of the plaster and improve the automation of production. Secondly, the online detection of Chinese plaster's viscosity provides a new method which can be applied in other industries to real-time online monitor and control viscosity to enhance efficiency of production and ensure product's quality.
