| Summary: | 碩士 === 國立中央大學 === 電機工程研究所碩士在職專班 === 99 === Following the progressive developments of civilization in the 21st century, the advanced medical care technologies improve the life quality of human life and consequently prolong the mean lifetime of human. To achieve a better efficiency in the distribution of medical resources, telemedicine and remote-monitoring have drawn great attention which provide flexible solutions to save the commutation time for patients and the clinic space for hospitals.
In recent years, techniques for remote monitoring of bio-signal transmission have been built based on wireless communication technologies, such as GSM、Bluetooth、wireless network, etc. However, drawbacks might arise due to the high demand of system complexity in these wireless communication system and deterioration of signal quality caused by the interference, transmission attenuation, or multi-reflection during transmission. Accordingly, a cheap communication approach for remote monitoring with high reliability and widely-constructed network is need.
In this thesis, a remote-monitoring channel has been constructed based on home telephone networks. Only a microprocessor is required to modulate the electrocardiac signal and transmit to remote health care centers. The proposed technology may provide a cheap and convenient way for constructing a remote homecare system.
