The Design And Development Of Community Telemedicine Monitoring Terminals

Telemedicine monitoring, especially the electrocardiogram(ECG) monitoring, plays an important role in improving the quality of people's lives and promoting the healthy and harmonious development of the society. It is an international research hot spot in recent years. This article presents an ECG signal sampling scheme based on wireless technology. It also introduced the key technologies and the design of software and hardware. Besides, the research of wavelet analysis based on Matlab and the applications of wavelet analysis in ECG signal processing is illustrated. Finally, the direction of further research is discussed.The main content of this thesis is as follow:1. Firstly, the current situation of telemedicine research in the domestic and international is introduced, and several typical telemedicine systems are bringed forward and compared in detail. Secondly, the history of wavelet theory and the development of its application in ECG signal processing are introduced.2. We introduce the composition of the community telemedicine monitoring system, and the design of hardware, software and wireless module of wireless ECG signal sampler. The design of signal amplifying and filtering circuit, MSP430 microprocessor and nRF905 wireless module are described in detail.3. We introduce the wavelet analysis theory which includes basic knowledge, multi-resolution analysis and common wavelet.4. The research of ECG signal processing based on wavelet analysis is introduced, and the noise reduction and compression techniques of ECG signal are especially detailed. We selected wavelet coif3 in application and achieved good results.5. At last, we discussed the direction of future research.
