Research Of Robust "Three Regions Nine Subdivisions" Finger-simulation Pulse Diagnosis System

The engineering realization of traditional Chinese medicine(TCM)pulse diagnosis is an indispensable part of the objective development and inheritance of TCM.Architecturally,the comprehensive and lossless acquisition of the human pulse signals based on engineering approach is the principal step.As expected,in the current study,many researchers have conducted in-depth explorations on the collection and recovery of pulse,the extraction of the characteristics of fluctuations,frequency,pattern and trend,and the correlation between the above information and the human body homeostatic.Important albeit that,existing pulse acquisition equipment are always constrained to the limitations of monotonous information acquisition methods,the missing of dynamic information such as pulse tendency.Further,they still over-reliant on Chinese medicine practitioners for arrangement of sensors and fingering.In view of the above imperfections,we rely on the extensive literature research,combined with a robust intelligent robotic device,supplemented by mature signal conditioning and transmission modules and a powerful PC control platform.Consequently,we designed a high stability "three regions nine subdivisions" finger-simulation pulse acquisition system.There is empirical evidence for the low-power STM32F429VGT6 microprocessors with sufficient excellent core performance to thoroughly meet the hardware core requirements of our system.Based on this microprocessor,we have designed functional circuits to complete amplification and filtering of weak biological signals,as well as efficient transmission of signals.Crucially,we have utilized substantial literature research as a theoretical support,related about the fingering during the pulsing diagnosis of TCM practitioners,and conducted engineering simulation of five typical methods and two special methods of fingering.With the effective combination of intelligent robot arm,piezoresistive sensor,conditioning and transmission circuit and computer,our system was successfully built.To be specific,we have achieved the adaptive optimized traversal based on "seeking method" to calibrate the pulse acquisition location,and the detailed design and precise control of various parameters in the multi-class fingering mode,such as pulse signal extraction pressure,moving path of robot arm probe,displacement length of single trial and signal acquisition time on each point,etc.,which make the finger-stimulation processes more flexible and comprehensive.It has made breakthroughs in the limitation of traditional pulse diagnosis equipment over-reliant on professional practitioners.Accordingly,it realizes the acquisition and visualization of valuable dynamic information which is a new attempt on the engineering simulation of TCM pulse diagnosis.By performing the four-dimensional coordinate information acquisition experiment of the optimized pulse acquisition position,a universal initial point of the Guan regions is established.Similarly,the coordinate information under the conditions of the maximum and the minimum pulse acquisition pressure is collected to establish a universal pulse pressure parameter.The establishment of these parameters significantly shortens the time required for the adaptive location regulated traversal process of the system.Furthermore,the pulse acquisition experiment proves the effectiveness of the system in the calibration process of the pulse acquisition location.Simultaneously,it refers to the richness of the information obtained under various static and dynamic modality.In summary,it provides new approach for the engineering and objectification process of TCM pulse diagnosis.
