Abstract

Practical test items were analyzed to extend the existing scoring method for boat operator licenses to an electronic scoring method. We have attempted to digitize the method within the current practical test system scope and have developed an electronic scoring system using LiDAR sensors and WAVE communication. The results of the study are as follows; the first, the scoring data entered into the LiDAR and examiner score device on the boat were transferred from an integrated processing unit to a land control center through WAVE communication. The system was constructed and verified to store and manage examinee data. Second, when testing the meandering task, accurate distance measurement was achieved by using LiDAR instead of visually observing the stick (3 m), and an accurate distance was displayed through the examiner score device quickly. Finally, we confirmed that it is possible to smoothly transmit and process the WAVE communication used to transfer the score data acquired from the boat to the monitoring center at a high speed without loss.

본 연구에서는 동력수상레저기구 조종면허의 기존 수기채점방식을 전자채점방식으로 전환할 수 있도록 실기시험항목을 분석하여 현재의 실기시험 시스템의 개념을 해치지 않는 범위 내에서 디지털화할 수 있는 방안을 모색하고, LiDAR센서와 WAVE통신을 통한 전자채점 시스템을 개발했다. 연구를 통해 얻은 결과는 다음과 같다. 첫째, 시험선에서는 LiDAR 및 시험관 평가입력장치를 통해 입력된 채점 데이터가 통합처리장치에서 WAVE통신을 통해 육상 관제센터로 전송되어 응시자의 데이터를 저장/관리할 수 있는 시스템을 구축 및 검증했다. 둘째, 사행 과제를 평가함에 있어서 기존에 목시관측 또는 막대기를 사용한 것을 대신하여 LiDAR를 이용함으로써 정확한 거리측정이 가능해졌고, 정확한 거리정보를 시험선 통합처리장치를 통해 시험관 평가입력장치에 신속하게 표출했다. 셋째, 시험선에서 취득한 평가점수 데이터를 육상 관제센터로 유실없이 고속으로 전송하기 위해 활용한 WAVE통신에서 원활한 전송 및 처리가 가능함을 확인했다.
