Traditional-Chinese-medicine pulse condition detection and signal conversion system and method

Abstract

The invention belongs to the field of traditional-Chinese-medicine pulse diagnosis, and particularly relates to a traditional-Chinese-medicine pulse condition detection and signal conversion system and method. The traditional-Chinese-medicine pulse condition detection and signal conversion system comprises a pulse condition detection device and a signal conversion device. The pulse condition detection device comprises an electret microphone, a microphone coupling cavity, a pressure sensor, a fixing device, a pressurizing device and an air bag pressurizing and depressurizing module. The signal conversion device comprises an impedance conversion field-effect tube, a low-pass filtering circuit, a signal amplifying circuit, a high-pass filtering circuit, a shifting circuit, a positive integrating circuit, a microcontroller and a computer. The output end of the impedance conversion field-effect tube is connected with the low-pass filtering circuit. The low-pass filtering circuit, the signal amplifying circuit, the high-pass filtering circuit, the shifting circuit and the positive integrating circuit are sequentially connected. The microcontroller is connected with the computer to display pulse condition graphs. The traditional-Chinese-medicine pulse condition detection and signal conversion system and method have the advantages that the pulse condition detection device collects sound signals and processes and converts the sound signals into pulse condition pressure signals, and a doctor is assisted to make diagnosis according to a pressure pulse condition graph clinical diagnosis standard.

Description

technical field [0001] The invention belongs to the field of pulse diagnosis of traditional Chinese medicine, and in particular relates to a system and method for pulse detection and signal conversion of traditional Chinese medicine. Background technique [0002] Pulse diagnosis is a treasure of traditional Chinese medicine. In traditional pulse diagnosis, the judgment of pulse condition depends on the feeling under the doctor's finger, and the diagnosis result is greatly affected by subjective factors. In recent decades, with the rapid development of sensing technology, scholars have combined the objective research of traditional Chinese medicine with modern sensing technology, and developed various pulse monitors to collect pulse information, thus making the pulse diagnosis of traditional Chinese medicine tend to be more objective. , digitization, and visualization. [0003] At present, the pulse detection system based on piezoresistive sensors is the most widely used in ...

AI Technical Summary

Problems solved by technology

However, the current research on the pulse sound signal only analyzes it in the time-frequency domain, and does not correspond to the pressure pulse signal of traditional Chinese medicine, so it cannot be recognized and applied in the clinical diagnosis of traditional Chinese medicine.
