The Research On Remote ECG Monitoring System Based On GPRS

With the improvement of living standards, people are more ligneous than ever before. There are more and more elders in the society, heart and cerebrovascular diseases have become a serious menace to human life, cardiopathy has become the highest mortality disease on the world. If there is an ECG monitoring equipment which can test patient's ECG signal conveniently, and quickly transmit the ECG signal data to health center when ECG is abnormal, doctors of the care center will provide medical guidance to patient timely, and cardiopathy patients will be safer.The rapid development of information technology and communication, especially the improvement of mobile communication makes it possible to realize remote ECG monitoring. In this thesis, I introduce the scheme of remote ECG monitoring system based on GPRS. It can monitor the patient's ECG and send ECG data to the health care center, the doctor of the center will quickly make some diagnosis, and give some rescue to the patient. This system can make the cardiopathy patients safer.The ECG monitoring system includes user monitoring terminal and hospital care center. User terminal includes ECG collection module, signal processing unit, and GPRS module. ECG collection module collect ECG signal and make some processing, such as magnifying, disturbance flitting, and gain control. The collected ECG signal will be sent to signal processing unit, whose CPU is TMS320LF2407A, Operating System is μC/OS-Ⅱ. The unit will process ECG signal, make a diagnosis, and display different results with light emitting diodes in different colors. When the ECG is abnormal or the user wants the ECG to be diagnosed by doctor, DSP will send ECG data to hospital care center by GPRS module MC39I. The PC server of care center will receive ECG signal and display it, and the doctor will give the patient a diagnosis and tell the patient what to do. If necessary a doctor will go to rescue the patient.In the system ECG data was transmitted by GPRS, it is wireless and very convenient for patient to use. GPRS can provide a high transmission speed (MAX: 171.2kbp/s), which is the highest-speed, practical and most widely used mobile network in China.
