Design Of A Wearable ECG Remote Monitoring System Based On Android Platform

With the development of IC technology and embedded system design,wearable devices are becoming very popular in families because of their comfort,practicability and durability.The system proposed in this thesis is based on Android platform and Tornado Web framework.The system consists of three parts,(1)Signal acquisition module,which digitizes ECG signal with on-board ADCs and transmits ECG data to an Android terminal with low-power Bluetooth.(2)Android terminal,which processes ECG data and display ECG waveform on screen.The Android terminal is capable of saving ECG waveform locally,as well as uploading ECG waveform to the Tornado Web server.(3)Remote Web server,which is responsible for receiving ECG data uploaded by terminals and storing ECG data on the server.The server is capable of managing multiple users and supporting multi-user registration,login,query and other functions.After logging in the system,user is able to view his basic information,history ECG waveform data and current data,and download his ECG waveform image with a Web browser.The system is intended for individuals and hospitals.An individual can acquire ECG data by the signal acquisition module,record and view ECG waveform and respiratory rate on an Android terminal,and upload ECG data to the servers of hospitals.With the Web servers based on Tornado,doctors in hospital can have access to their patients’ ECG data and perform remote diagnosis.This thesis describes the overall design framework of the remote ECG monitoring System and the implementation of functions such as display and analysis.The system is capable of 24-hour continuous ECG monitoring with single lead.Doctors can easily manage the information of their patients and check the data uploaded by the patient to make remote diagnosis.
