Abstract

This paper aims to build a home security system based on IoT to monitor a home on a mobile phone. The system consists of data gathering sensors, camera, gateway and Xively platform. The Raspberry Pi collects data from the three sensors and sends the data to Xively, and sends the video stream of home to a client in a smart phone through a internet. The servers are composed of Xively, socket server in Raspberry Pi and E-mail server in Google. The proposed system transmits e-mail, text message, and video stream when there are motion, fire, and gas leakage, and can control the gas valve through Raspberry Pi. The experimental results show that a user gets 'emergency E-mail' and text message and watches the video stream of the home through WIFI or LTE on a smart phone.

본 논문은 휴대폰에서 사용할 수 있는 IoT 기반 홈 보안 시스템을 개발한다. 제안된 시스템은 데이터를 수집하는 센서, 카메라, 게이트웨이와 Xively 플랫폼으로 구성된다. 라즈베리파이는 3 종류의 센서로부터 데이터를 수집하고, Xively로 데이터를 전송하고, 카메라의 영상화면을 인터넷을 통하여 휴대폰의 클라이언트로 전송한다. 서버는 Xively, 라즈베파이에 존재하는 소켓 서버와 Google에 있는 이메일 서버로 구성된다. 제안된 시스템은 움직임, 화재 위험, 가스 누출이 발생하면 이메일, 텍스트 문자와 영상화면을 전송하고, 라즈베리파이를 통하여 가스 밸브를 제어할 수 있다. 실험결과로부터 가스 누출 등으로 위험이 발생하면 사용자는 이메일, 문자 메서지를 전송받고, WIFI 또는 LTE를 통하여 스마트폰으로 집내의 영상화면을 볼 수 있다는 것을 확인하였다.
