Abstract

The general ground control system has control and information display functions for the operation of a single unmanned aerial vehicle. Recently, the function of the single ground control system extends to the operation of multiple UAVs. As a result, operators have been exposed to more diverse tasks and are subject to task overload due to various factors during their mission. This study proposes an adaptive ground control system that reflects the operator's condition through the task overload measurement of multiple UAV operators. For this, the ground control software is developed to control multiple UAVs at the same time, and the simulator with six degree-of-freedom aircraft dynamics is constructed for realistic human-machine-interface experiments by the operators.

일반적인 지상통제 시스템은 단일 무인항공기 운용을 위한 통제 및 정보 전시 기능을 갖추고 있다. 현대에서는 단일 지상통제 시스템을 사용하여 복수 무인항공기의 운용이 요구되고 있다. 이로 인하여 무인기 운용자는 과거보다 다양한 임무 수행이 요구되며, 임무 수행 중 다양한 요인에 의하여 임무과부하를 받게 된다. 본 연구에서는 복수무인기 운용자의 임무과부하 측정을 통해 운용자의 상태를 반영한 적응형 지상통제 시스템을 제안한다. 복수무인기를 운용할 수 있는 지상통제 소프트웨어를 개발하고, 또한 시뮬레이터를 구성하여 운용자가 지상통제 시스템의 운용을 통해 시스템의 기능을 검증한다. 적응형 지상체 실험을 분석한 결과, 비적응형 지상체 실험 결과와 대비하여 운용자의 동공지름이 감소하고, 임무 성능이 증가하는 등 적응형 지상체의 효용성을 확인하였다.
