Abstract

The characteristics of wind sensors were experimentally analyzed and compared for purposes of application in multicopter type drones. For rotating wind sensors, the dynamics effect causes measurement errors, while manufacturing errors and signal processing errors were found to constitute significant errors in ultrasonic sensors. In the ultrasonic sensor, the errors decrease as the distance of the transducer increases. These characteristics were experimentally confirmed, and it was established that ultrasonic sensors capable of outputting voltage or data of 10 Hz or more are suitable for use in multicopters.

멀터콥터형 드론에 적용할 목적으로 바람 센서의 특성을 분석하고 실험을 통하여 비교하였다. 회전식 풍속계의 경우 동역학 효과가 측정 오차를 만들며, 초음파식 센서는 제작 오차와 신호처리 오차가 주요한 것으로 나타났다. 초음파식 센서는 트랜스듀서의 거리가 멀수록 오차가 줄어든다. 실험을 통하여 이러한 특성들을 확인하였으며, 멀티콥터에는 전압 출력 혹은 10 hz 이상의 데이터 출력이 가능한 초음파식 센서가 적합하다고 판단한다.
