無線個人區域網路(Wireless Personal Area Network ; WPAN)的概念,就是將生活環境週遭的設備,如手機、PDA、電腦週邊與其他資訊家電等,以短距離且低功率的無線網路的技術連接起來。無線感測網路(Wireless Sensor Network ; WSN)便是實現WPAN的一種技術,利用散佈在特定區域的各網路節點來建構一個低成本、低功耗且低傳輸率的無線網路,其應用範圍包括居家設備自動化、工業控制、遠端監控及醫療照護等。 本論文將提出一套利用ZigBee來實現的無線感測網路系統。我們使用嵌入式控制器與ZigBee晶片來實現一個可程式化的網路節點,並以C語言來撰寫適合的傳輸規則與溝通邏輯。利用個人電腦與數個網路節點以分散式的架構來建立一個以個人電腦為中心的無線感測網路系統,最後結合輪型機器人來實現動態物體的軌跡追蹤。
The idea of Wireless Personal Area Network (WPAN) is using a short range and low power wireless network technology to connect certain devices such as cell-phones, PDAs, computers and peripherals and other home appliances. Wireless Sensor Network (WSN) is one of the technologies to realize WPAN. It can setup a low cost, low power and low data transfer rate wireless network in a particular area by deploying several network node. The applications include building automation, industrial control, remote control and healthcare. This thesis proposes a wireless sensor network system using ZigBee. We use embedded controller and ZigBee module to implement a programmable network node, and compile suitable transmission protocol and communication logics. We set up a wireless sensor network in distributed structure by several network nodes and PC, in which PC is the master control center. Finally, we would combine this system with a wheeled-robot to verify its efficacy in the movable object location estimation and loci tracking.
