摘要

針對當前高齡者易走失及跌倒的現狀，以及目前市場上基於GPS定位技術構建位置跟蹤系統的局限性，本文主要結合ZigBee無線感知網路、位置感知及跌倒偵測等無線通訊技術開發適合於高齡者之「遠距照護系統」，達到預防走失，偵測跌倒及緊急救護之目的。透過構建無線感知網路在社區或養護中心，對高齡者的相對位置進行動態監測，同時判斷是否發生跌倒狀況，當偵測到其跌倒時，判定其跌倒位置並及時發出救援警示。老人隨身佩帶的裝置體積小、耗電少、易於佩帶，且能在室內與室外環境中使用。

With the current situation that the elderly get lost and fall easily, as well as the limitations of the tracing devices based on the GPS locating technology in the market nowadays, this paper applies wireless communication technologies which combine localization technology in ZigBee-based wireless sensor networks with fall detection technology to the development of a telecare system. The system can prevent lost, detect fall and provide timely medical care for the elderly. By constructing a wireless sensor network in the community-care models and the institutional-care models, the relative position and fall situation of the monitored elderly can be detected simultaneously in time, and then gives alarm to provide timely medical care. The wearing device of the elderly is small, low power consumption and convenient, and can be used in indoor and outdoor environments.
