The Design Of Wireless ECG Sensor Terminal

As patients and high mortality from heart disease continues increasing, early correct diagnosis and timely treatment are crucia. ECG is widely used to examine and analyse heart disease. In hospital ECG detection is short. Furthermore the doctors only get a small amount of state information. As ECG signal acquired is static data, the probability to find heart disease is quite low. So exercise ECG has its unparalleled value. On the market the ECG monitoring system usually integrate ECG data acquisition, display and transmission module in just one equipment.We considered separating the function of ECG collection, display, storage and analysis with smart phones. Combined with the acceleration data acquired from acceleration sensor in Android mobile phone, we realize the real-time matching of ECG signal analysis and motion scene.Firstly this paper introduces the research background and significance related at home and abroad.On the basis of it,the paper elaborates the implementation of the front and back module for ECG signal acquisition and central server.According to medical value of exercise ECG signal,we realize functions of accelerometer signal acquisition. Furthermore the paper realizes the funcitions of storage and display three axis accelerometer data on Android mobile phone. Finally it elaborates acceleration signal analysis and results of activity recognition.The research contents involved are below:(1)Designing a complete system of ECG signal acquisition, transmission, processing and storage system: the A/D conversion, Bluetooth communications in SCM; the ECG signal receiving, storage and analysis in Android mobile phone; the building between remote central server and ECG remote storage.(2)Designing full acceleration signal acquisition, storage, display and transmission module with acceleration sensor in Android mobile phone.(3)Using the base classifiers and Plurality Voting algorithm to achieve different activity predictive classifications with the characteristics of the acceleration signals.
