摘要


Zigbee是屬於無線個人區域網路中一種應用,目前的協定架構上是採用IEEE 802.15.4 (Low-Rate Wireless Personal Area Network,LR-WPAN),其具有低速率、傳輸距離短、低功率、架構較簡單成本低、體積小等特性。本論文將應用目前最新的無線傳輸技術-Zigbee來發送訊號,以及監控管理平台判斷是否有火災、一氧化碳、墜樓事件,控制警報系統是否應該開啟。利用Zigbee建置一套居家安全資訊系統,使用最低的成本,最方便不需佈線的無線感應,用來預防火災、一氧化碳、墜樓事件,讓家裡成為最安全的地方。 我們所使用的感測器可依環境需求做適時的調整,讓前端感測器的部份可以正確的感應四周的情況。在傳輸訊號方面也因應目前最具挑戰的無線傳輸技術,讓無線技術可以推向生活化且隨時充斥在生活應用當中,而不是只有相關研究人員或追求新產品的少數人使用,讓大家可以了解無線技術的方便性以及人們對無線技術的需求。 本研究所使用的ZigBee晶片其倡導平價化,讓無線技術使用者不再是有錢人的專利,在未來大量使用時其晶片最低可降至一元美金,讓大家顛覆對3C科技產品價格高高在上的觀念,如此一來此ZigBee將容易受到大眾的喜愛也很容易將此技術拓展至全世界。

並列摘要


ZigBee is one of application of wireless personal area network technology. The current protocol is IEEE 802.15.4, that is a Low-rate, Wireless Personal Area Network (LR-WPAN) structure. It has a number of specific features such us low rate, short distance, low power, structure simple, low cost, and small size. The research is to employ the advanced wireless transmission technology of ZigBee to transmit signal as well as to monitor and control the platform that whether will be activated or not. Should the events of fire alarm be trigged, carbon monoxide and fall occurs. In order to prevent the further damages in case of fire alarm, carbon monoxide and fall, ZigBee will be built as one of economic Home Safety Information System. The sensors that we adapted can be adjusted to meet the requirements of environment changes. With respect to transmit signals, we apply a current most challenge wireless technology to serve not only small group of researchers or new product seekers but all who want to know the convinence of and to acquire the wireless technology. The research in to advocate the low cast ZigBee technology. It’s ultimate goal is to reduce the cost of a ZigBee chip to one US dollar. It will no longer belong to the wealth people but to all who get used to the high price of 3C product, Therefore the ZigBee will then be easily accepted by the people who love and so does the whole world.
