Figure 1. The System Overview
The ARM-based platform is the primary hardware device which was placed near
the door inside. It has three paths of data flowing. One is the door controlling path
which includes four peripherals and two signals, the peripherals are a RFID reader, a
keypad, an alarm, a camera which were placed at home outside or it can be embedded
in the door; the signals are a door opening detection and a door opening control that
was simulated with two IO signals of the ARM-based platform. The second path is
Ethernet network which connects to internet via an ADSL modem in home, this thesis
supposes the internet connection was already existed, therefore the ADSL modem just
the concept for connecting to internet in home. The third path is WiFi network which
provides the WiFi entertainments when the entrance system was idled. The WiFi
entertainment system such as a media center, it includes the MP3 music and digital
photos, the family can playing the music and viewing the photos anywhere at home
