Abstract

The use of the Internet of things plays a major role in the Fourth Industrial Revolution, and a series of tasks of accumulating, converging, analyzing and reusing various data and services becomes very important. Because the pace and scope if the paradigm shift in Fourth Industrial Revolution is so rapid and unpredictable, the development and utilization of a system to fulfill this role for IOT are urgently required. In this paper, we introduce the Web-based IOT management system, which connects the IOT with OKMindmap, which is a domestic open source software and service, and the Node-RED service. This system combines the advantages of OKMindmap with the advantages of Node-RED, which is capable of visual component based programming, so that it can easily and flexibly connect the IOT based on Web browsers, and various data and services can be integrated and linked. We developed a camera module, a temperature and humidity sensor module, and the motor control module in Raspberry PI basically, and tested the operation successfully. We plan to extend the IOT component gradually by using Arduino and System On Chip.

사물인터넷의 활용은 4차산업혁명 시대의 핵심으로 다양한 데이터와 서비스를 축적, 융합, 분석하여 재활용하는 기본이 된다. 4차 산업혁명의 발전 속도와 사업 전환의 패러다임이 급격히 변화하고 예측하기 힘든 상황에서 사물인터넷을 연계하고 관리할 수 있는 시스템과 프레임워크가 요구된다. 본 논문에서는 국내 오픈소스이며 서비스인 OKMindmap에 사물인터넷을 접합하고 Node-RED 서비스를 연계하여 사물인터넷 관리시스템으로 개발하였다. 개발된 시스템은 OKMindmap의 장점과 프로세스적 프로그래밍이 가능한 Node-RED의 장점이 결합되어 쉽게 설치할 수 있으며 웹 브라우저 기반으로 사물인터넷을 연결하고 다양한 데이터 및 서비스 변환 및 연계를 할 수 있다. 라스베리파이에 카메라 모듈, 온습도 센서 모듈, 전동기 제어 모듈을 개발하여 기본적인 기능을 구현하였으며, 점차 아두이노와 SOC 등의 사용으로 연계 소자들을 확산해 나아갈 계획이다.
