전자종이와 Bluetooth 통신 기반의 디지털 도어사인 관리 시스템 구현

다국어 초록 (Multilingual Abstract)

In this paper, we proposed and developed a digital doorsign management system based on E-paper and Bluetooth which user can choose design type for noticing information by space use and doorsign size and minimize the power consumption of doorsin.
The proposed system registers templates for design type information and automatically generates notice of the selected design type by using information of the template and user. The notice is converted to EPD(Electrophoretic Display) file format for being displayed in E-paper and transmitted into digital doorsign via smartphone application. For minimizing power consumption of digital doorsign, we adopt E-paper display and Bluetooth LE-BR/EDR hybrid protocol in EPD file transmission. The digital doorsign is BLE mode in standby and Bluetooth BR/EDR in data reception.
By the proposed system, users can display notice reflecting his preference. We can reduce maintenance expenses of the digital doorsign by low power consumption. And also we can enhance utility of the digital doorsign, because users additionally communicate with random visitors by notice which can input any time with smartphone application.
