摘要

隨著醫療科技的進步，心電訊號被廣泛地用來長期監測異常的心臟生理現象。當心臟病患在家中或醫療院所發生如心室顫動(Ventricular Fibrillation)等異常狀況時，若沒有一套有效警報機制通知醫護人員，常是造成患者猝死的主要原因。為了提供心臟病患者在接受監控與診療的同時，還能擁有正常的生活品質，本文發展一套具有省電與同步機制之感測器網路（Wireless Sensor Network, WSN），以長時間監控心臟病患生理參數並提供緊急救援服務。
本系統整合感測技術、嵌入式計算與無線通訊技術，以研製一組提供低功耗、低成本之感測節點硬體架構，並配合自行研發之網路通訊協定，以實現具有省電與同步機制之感測器網路。藉由在病患家中建置無線感測器網路，無論病患在家中休息或活動中，系統可透過詢問模式隨時監控病患的生理參數，一旦發生緊急狀況時，系統可透過簡訊緊急通知醫護人員進行救援行動，以提供良好的遠距照護服務。

In view of the development of medical technology, electrocardiogram (ECG) signal have been broadly used to monitor abnormal biomedical signals of heart over a long period of time. If people can not become aware of emergency right away when something bad happen to cardiac patients such as Ventricular Fibrillation, it is quite often the main reason to cause the sudden death of them. In order to provide cardiac’s normal standards of living and protect their live security, this article develops a tele-emergent system over wireless sensor network (WSN) to provide constant monitoring of cardiac patients.
By intergrating sensor technology, embedded operation technology, wireless communication technology, sensor nodes with low power consumption and low cost have been designed. By intergrating the sensor node and network protocol which we design, a power-saving and clock synchronization scheme over wireless sensor network have been accomplish. By setting up the sensor nodes at patient’s home, physicians could monitor their physiological function remotely and constantly. When patients don’t feel well, the human body gateway could get the emergent signal through wireless sensor network by multi-hopping method. Our goal is to enable continuous real-time monitoring of physiological data in bi-direstional way which is vital for one’s patient’s medical care and welfare.
