本文提出應用 ZigBee 無線感測通訊協定為基礎去建構一個數位影音導覽系統。在軟體部分,我們利用C#程式語言開發一個數位影音導覽的雛型系統。在通訊傳輸部分,本論文採用廣播(broadcast)發送的方式作為感測器發送端與使用者接收端之間的傳輸方式,並且針對感測器佈置的環境(展覽廳、走廊與戶外)、距離、擺放位置、發送功率和發送端與接收端數量(Single Case、Multiple Case)的差異,對接收訊號強度(Received signal strength indication, RSSI)及封包接收是否出現遺失進行量測並分析。根據實驗量測的結果我們提出一些在展覽場所佈置ZigBee導覽系統的參數配置建議。當 Power level為 7 時,封包發送範圍在15M時其loss rate低於0.2。若以每0.5秒發送一次,則一秒內連續兩次 loss 封包的機率為 0.2*0.2=0.04,即每秒的封包傳送達成率為1-0.04=0.96,封包傳送達成率相當高,是一個不錯的設定參考值。
In this thesis study, we designed and developed a digital guide system based on Zigbee communication, which supported various media, such as audio, video, graph, and text, to provide rich context for each exhibition items. ZigBee is a new communication protocol for wireless sensor networks (WSN), which has various advantages such as low transfer rate, low power consumption, low cost, and supporting large number of network nodes, to name a few. In recent years, wireless sensor networks have been applied to different fields, such as industry, commercial, and home
applications. We use broadcast transmission mechanisms to disseminate information of exhibition items nearby. For better understanding the communication qualities over different environmental settings, we conducted intensive experiments on the measurement of signal quality in terms of RSSI (Received signal strength indication) and packet error rate. We considers different factors such as location (e.g. exhibition rooms, corridors, and outdoors), position (e.g. on/off the corners), distance, and transmission power. Basing on our measurement results, we found a possible setting for the guide system is with Power Level 7 and transmission frequency of 2 messages per second, which would results in message successful probability of 0.96 within a transmission distance of
15-meter.
