Abstract

The start of the Fourth Industrial Revolution has brought about various changes in the domestic industry in general, and smart factories have spread to companies in the fields of production, manufacturing and logistics, and they are using automation equipment. Especially in the field of logistics automation, AGVs are widely used, and most of them use the line guidance system, which is the traditional AGV drive system. In addition, the demand for AGV system developers, system operators and managers, and maintenance personnel is increasing, and the installation of systems for education is expensive and requires a large space to utilize. It is a situation where systematic education is difficult. In this paper, we propose a virtual simulation-based AGV distance education model for smooth practice of trainees. The proposed model consisted of a model that can drive the AGV by analyzing video information, instead of the line guidance method that is the conventional technology. As a result of self-diagnosis evaluation, it was confirmed that the experimental group through online education had an average satisfaction level of 0.65 higher than the control group using existing equipment, and that it could be used in an online education environment.

4차산업혁명의 시작은 국내 산업 전반에 다양한 변화를 가져오고 있으며, 생산 제조 및 물류 분야의 기업에 스마트 팩토리가 확산되면서, 자동화 설비를 사용하고 있다. 특히 물류 자동화 현장에서는 AGV가 널리 사용되고 있으며, 전통적인 AGV의 구동 방식인 라인 유도 방식의 사용이 대부분이다. 또한 AGV 시스템 개발자 및 시스템 운영자 및 관리자, 유지보수 인력의 수요도 증가하고 있는 추세이나, 교육을 위한 시스템의 설치에 고가의 비용이 소요되고, 넓은 공간을 필요로 하는 특성을 가지고 있어, 체계적인 교육이 어려운 상황이다. 본 논문에서는 교육생들의 원활한 실습을 위하여 가상 시뮬레이션 기반의 AGV 원격 교육 모델을 제안한다. 제안 모델은 기존 기술인 라인 유도 방식이 아닌 영상 정보를 분석하여 AGV를 구동할 수 있는 모델로 구성하였으며, 자가진단 평가 결과 기존 기자재를 활용한 통제 집단 보다 온라인 교육을 통한 실험 집단이 평균 0.65의 만족도가 상승하여, 온라인 교육 환경에서 활용할 수 있는 가능성을 확인하였다.
