碩士 === 國立虎尾科技大學 === 電機工程研究所 === 101 === This master thesis proposed a device identification method based on the connection property of Wi-Fi and Bluetooth to reduce human operating. The method of device identification integrates with RFID and NFC technology, and implements a door control system with the hybrid wireless identification technology based on Wi-Fi and Bluetooth. This system is divided into three subsystems: Door Controller (DC), Door Control Gateway (DCG) and Door Control Center (DCC). DC is separated to two types according to the ability of the controller: High-End Door Controller (H-EDC) and Low-End Door Controller (L-EDC). Such controllers can identify user device with wireless technologies and control door lockers. In the proposed system, each area has a DCG, and each DCG connects to DC. Thus, DCG also is a bridge between DCC and DC. DCs will send identification records to DCG. The identification record can be shown and stored on the DCG. The DCC is to manage multiple DCGs. Moreover, DCC provides the functions of system management and door-access log for administrators and users. Additionally, the system performance was measured, and the identification time of H-E/L-EDC is less than 31ms. Therefore, according to the result of system performance, the human operating can be reduced when using the door control system with hybrid wireless identification technologies.
