使用WiFi/PDA無線網路技術建置音樂自動播放系統—以國小校園為例

在校園環境中，傳統的人工操作音樂播放方式是既費時又費力。在資訊科技發達的今日，這是可以被無線網路音樂自動化播放系統改善的。整合網際網路及無線網路等技術的無線網路音樂自動化播放系統，除了固定時間能自動播放所需要的音樂外，在特定的活動場合，也能隨時因應需求，隨機播放所需要的各種音樂。本研究的目的，在探討如何以一般個人電腦建構一個低成本、高效率且自動化的無線網路音樂自動播放系統，以減少繁瑣的音樂播放人力。並且透過有線的網際網路、無線區域網路、或活動性高的PDA行動裝置遠端控制，除了可以做到定時播放的功能外，也能發揮傳統播放方式無法達到的無線網路遠端即時播放功能。本系統是將現有的網路技術，如 PHP 動態網頁、無線網路、網際網路、MySQL資料庫、和Unix-Like的作業系統，導入無線網路音樂自動化播放系統中。透過此系統，可以遠端設定每天定時播放的音樂。例如：學生上學時，播放系統將自動播放輕鬆和諧的音樂，學生感受到美好的音樂氣氛，自然能帶著愉快的心情，開始一天的學習；在運動會的場合中，教師手持 PDA 等行動裝置，當運動員進場時，只要點按一下 PDA 畫面，校園便開始播放起雄壯威武的行進音樂，讓典禮能在莊嚴隆重的音樂氣氛下順利進行。

In the campus, it will take much time and manpower to operate the traditional artificial music broadcast system. In the information age, it is possible to implement a wireless music broadcast system to improve the flaw of the traditional artificial music broadcast system. The wireless music broadcast system is made by integrating the Internet technology and the wireless technology. It not only can broadcast the needed music in set time automatically, but also can randomly broadcast various kinds of music at any time or any specific place through the mobile devices such as PDA. The purpose of our research is to implement a high efficient music broadcast system with a low cost to broadcast the music without extra manpower. This system can broadcast the music through the Internet or wireless networks. Moreover, it can process the broadcast in real time which is not seen in the traditional music broadcast system. The system will integrate the existing network technology such as PHP dynamic webpage, wireless network, the Internet, MySQL database, and Unix-Like operation system. Through the system, the music can be broadcasted regularly every day. For instance, when students go to school, the system will broadcast the relaxing and harmonious music automatically. Students experience the beautiful atmosphere and are in a good mood at the beginning of a day. Taking another example, in sports meeting, a teacher can carry the mobile device such as PDA to broadcast the magnificent music when the athletes march into the arena. This enables the meeting to go on smoothly under the solemn atmosphere.
