초록

최근 4차 산업혁명의 핵심기술인 드론의 도입으로 학교 교육 현장에서는 드론을 활용한 다양한 융합교육이 진행되고 있다. 특히 자유학기제 수업 및 진로탐색과 연계하여 드론 이론 및 실습 교육을 진행하고 있다. 드론융합 교육프로그램은 단순 시연 실습교육 보다 학습자의 만족도가 높고 직접적인 실습 경험으로 인하여 학습효과가 높게 나타나고 있다. 그러나 다수의 학습자를 상대로 실습교육을 진행하고 있어 한정된 장소에서의 다중드론 비행에 제약 및 학습자 통제가 불가능한 실정이다. 본 논문에서는 학교에서 다중드론 교육 운영 시 교수자가 다수의 드론을 실시간 감시하고 드론 간의 충돌을 사전에 학습자에게 인식시켜 실시간으로 다수의 드론 감시가 가능한 감시시스템을 제안하였다. 실험에서 사용된 통신 모듈은 Murata LoRa에 GPS를 탑재하였고, 실시간으로 수신된 위치 데이터를 기반으로 모니터링이 가능하도록 서버와 클라이언트를 구성하였다. 개방형 공간에서 제안한 시스템의 성능을 평가하였으며, 약 120m 거리까지 통신 신호가 양호함을 확인하였다. 즉 240m 범위 안에서 25대의 교육용 드론의 제어가 가능하고, 교수자가 모니터링할 수 있음을 확인하였다.

Recently, with the introduction of drones, a core technology of the 4th industrial revolution, various convergence education using drones is being conducted in school education sites. In particular, drone theory and practice education is being conducted in connection with free semester classes and career exploration. The drone convergence education program has higher learner satisfaction than simple demonstration and practice education, and the learning effect is high due to direct practical experience. However, since practical education is being conducted for a large number of learners, it is impossible to restrict and control the flight of a large number of drones in a limited place. In this paper, we propose a monitoring system that allows the instructor to monitor multiple drones in real time and learners to recognize collisions between drones in advance when multiple drones are operated, focusing on education operated in schools. The communication module used in the experiment was equipped with GPS in Murata LoRa, and the server and client were configured to enable monitoring based on the location data received in real time. The performance of the proposed system was evaluated in an open space, and it was confirmed that the communication signal was good up to a distance of about 120m. In other words, it was confirmed that 25 educational drones can be controlled within a range of 240m and the instructor can monitor them.
