Abstract

It is most desirable to train with a real crane in an environment similar to that of a port for crane operation training in charge of loading and unloading in a port, but it has time and space limitations and cost problems. In order to overcome these limitations, VR(Virtual Reality) based crane training programs and related devices are receiving a lot of attention. In this paper, we designed and implemented a VR-based harbor crane simulator operating on an HMD. The simulator developed in this paper consists of a crane simulator program that operates on the HMD, an IoT driving terminal that processes trainees' crane operation input, and a training server that stores trainees' training information. The simulator program provides VR-based crane training scenarios implemented with Unity3D, and the IoT driving terminal developed based on Arduino is composed of two controllers and transmits the user's driving operation to the HMD. In particular, the crane simulator in this paper uses a training server to create a database of environment setting values for each educator, progress and training time, and information on driving warning situations. Through the use of such a server, trainees can use the simulator in a more convenient environment and can expect improved educational effects by providing training information.

항만에서 하역을 수행하는 크레인 운전 훈련은 항만과 흡사한 환경에서 실제 크레인으로 훈련하는 것이 가장 바람직하지만, 시공간의 제약과 비용적인 문제가 있다. 이런 제한을 극복하기 위해 VR(Virtual Reality)을 기반으로 한 크레인 훈련 프로그램과 관련 장치가 많은 관심을 받고 있다. 본 논문에서는 HMD 상에서 동작하는 VR 기반의 항만 크레인 시뮬레이터를 설계하고 구현하였다. 본 논문에서 개발한 시뮬레이터는 HMD에서 동작하는 크레인 시뮬레이터 프로그램과 피교육자의 크레인 운전 입력을 처리하는 IoT 운전 단말기, 그리고 피교육자의 훈련 정보를 저장하는 트레이닝 서버로 구성된다. 시뮬레이터 프로그램은 Unity3D로 구현한 VR 기반의 크레인 훈련 시나리오를 제공하고, 아두이노 기반으로 개발한 IoT 운전 단말기는 2개의 컨트롤러로 구성되어, 사용자의 운전 조작을 HMD로 전달한다. 특히, 본 논문의 크레인 시뮬레이터는 트레이닝 서버를 도입하여 교육자별 환경설정 값, 진도 및 훈련 시간, 운전 경고 상황에 대한 정보를 데이터베이스화하였다. 이러한 서버 이용을 통해, 피교육자는 좀 더 편리한 환경에서 시뮬레이터 활용이 가능하고, 학습 정보 제공에 의한 향상된 교육 효과를 기대할 수 있다.
