Research On Characteristics Testing Of Pulse Measuring System In Chinese Medicine

Access to a large number of related literatures to learn the status of the system and its characteristics at home and abroad. The method of characteristics testing of pulse detecting system is brought up. In this subject the characteristics of DY-SS-II pulse detecting system in Chinese medicine is researched.Description from signal process point, pulse signals decomposed into DC and harmonic components based on Dirichlet principle. A theoretical model of pulse detection system has been set up. Static and dynamic characteristics can be used to describe the system. The main indicators of static characteristics dynamic characteristics is analyzed. Transducer technology, information process technology, virtual instrument technology and computer graphics are used to analysis on pulse detecting system. Programmable gain amplifier circuit and A / D converter has been tested. Analyzing the reason of computer switching power supply causes electromagnetic interference and using filtering to inhibition. Through the test on different computers, testing the relationship between the machine configuration and MATLAB program execution speed.In this paper, balance is used to test characteristics of pulse detecting system. Testing methods of the static characteristics is described. Linearity and resolution is computed on MATLAB. The method of ynamic characteristics testing is described too. It is separating sensor and filter.This paper has mainly completed the analysis pulse testing, including the choice of sensors, signal processing part of the circuit design, A / D converter of choice, the use of virtual instrument platform MATLAB pulse preparation and analysis software to achieve pulse acquisition, waveform display , and print data. Through set up the pulse system mathematical model, put forward the method of testing dynamic nature and static characteristics of the system, design testing characteristics device of pulse detecting system, take the study on the characteristics of the pulse detecting system in MATLAB.
