Abstract

Recently, the Smart household appliances to provide Smart services have been actively spreaded by providing IoT(Internet of Things). Also, the appliances which Wi-Fi and Bluetooth can directly control are preferred. But until now, the most household appliances are based on IR(InfraRed) and the each procotols of them are different. In this paper, to solve these problems, we suggested the system to control both smart appliances and general appliances by using Smart phone. The system is "Wi-Fi to IR" gateway which receives the Wi-Fi signal to convert to IR signal and transmit it. Also, we made the remote control function in specific brands' appliances possible to most brands without limitation and tried to control not only one remote controller for one TV brand but also for all brand without limitation.

사물 인터넷의 보급으로 인해 스마트홈 서비스 기능을 제공하는 스마트 가전의 보급이 활발하게 이루어지고 있다. 이에 따라 스마트기기로 직접 제어할 수 있는 Wi-Fi 및 Bluetooth가 접목된 제품들이 선호되고 있다. 하지만 현재까지 개발된 가전제품은 IR(InfraRed) 기반의 제품이 많으며, 제품마다 호환되는 프로토콜이 다르다는 문제가 있다. 본 논문에서는 이러한 문제를 해결하기 위하여 스마트폰을 이용하여 스마트 가전 및 기존 가전제품을 제어하기 위한 시스템을 제안하고자 한다. 제안하는 시스템은 Wi-Fi 및 IR 게이트웨이로 스마트폰의 제어명령을 Wi-Fi를 통해 수신하고 이를 IR로 변환하여 기존 가전제품들을 제어하는 역할을 수행하도록 한다. 또한 특정 브랜드의 가전제품이나 특정 스마트폰에서만 지원 가능했던 리모컨기능을 제약 없이 사용가능 하도록 하고, 하나의 가전기기에 하나의 리모컨이 사용되는 한계점을 벗어나 모든 스마트폰을 이용하여 다양한 가전제품을 제어할 수 있도록 하고자 한다.
