System for identifying and diagnosing rheumatic heart disease based on sound sensors and diagnostic method

The invention discloses a system for identifying and diagnosing rheumatic heart disease based on sound sensors. The system comprises the plurality of sound sensors placed on the surface of a thoracic cavity outside a heart, and the sound sensors are all connected with a signal processing system which is connected with monitor terminal equipment. A method for identifying and diagnosing the rheumatic heart disease based on the sound sensors comprises the steps: placing the sound sensors on the surface of the thoracic cavity outside the heart, transmitting heart sounds detected by the sound sensors to the signal processing system, performing three-dimensional sound source positioning signal processing, and finally obtaining a position where cardiac souffle is made, wherein the position is shown on the screen of the monitor terminal equipment in icon and three-dimensional coordinate forms. The system and the method have the advantages that a cardiac souffle situation can be accurately obtained by auscultation, and the position of a souffle sound source can be exactly positioned and be displayed on a displayer in real time. By adopting the method and the equipment of the system, the rheumatic heart disease can be well diagnosed according to the heart sounds.
