數位家庭門禁管理與WiFi娛樂的設計與實現

Abstract

在數位家庭時代的來臨，必定有一個足以保護居家財產安全的數位大門，而本論文便是以此概念來設計與實現，一個兼容於現在一般家庭的門禁系統。另一方面，為了數位家庭的來臨，本論文亦加入無線且數位的娛樂，提供無線數位音樂廣播，與家庭數位照片相簿的無線瀏覽。

在系統的實現方面，本論文使用ARM-based為硬體平台，以Linux為作業系統，並整合了無線網路IEEE802.11b、USB PC camera、RFID module、密碼鍵盤等Device Drivers。而在軟體應用方面，本系統完成了：使用RFID tag與使用密碼鍵盤輸入密碼，達到雙重認證的功能；使用USB PC camera，提供門口影像顯示和支援手機的遠端監視功能；利用影像變動偵測達到自動錄影並存入遠端伺服器以及警報啟動並自動以簡訊通知手機的功能；使用無線網路，達到音樂無線廣播分享以及家庭相簿功能。

In the trend of digital home, it shall have an intelligent and securely digital door for protecting the personal property and security. With this concept, this thesis proposes an intelligent entrance system in a house. On the other hand, for the trend of digital home, this thesis is also a WiFi entertainment of digital music broadcasting and electrical photo album.

In this thesis, the system is an ARM-based embedded system with a Linux OS, and is integrated Linux devices drivers of a wireless card, a USB PC camera, an RFID module and a keypad. The software applications provide the two-tier identification entrance system which uses a keypad to input the password and an RFID tag for identification; a door camera which grabs the images for being shown on the LCD screen and supports remote monitor by cell phones; a motion detection function which invokes an auto recording function to record the images to remote server, and invokes the alarm and an SMS to cell phone; a WiFi entertainment with MP3 broadcasting and home gallery.
