초록
농업환경에서 농약방제는 농업인에게 작업 위험성과 높은 노동력을 요구한다. 무인항공기를 활용한 농약방제는기후, 토지형태, 무인항공기의 특성에 따라 효율성이 다르게 나타난다. 따라서, 살포조건과 환경조건을 고려한 효율적인무인항공기 농약방제 방안이 요구된다. 본 논문은 작물별 살포조건과 환경정보를 고려한 농업용 무인항공기 기반의 효율적인 농약 방제 시스템을 제안한다. 감수지 부착 후 고도 및 속도 변화에 따른 농약 낙하균일도 측정 및 작물 성장조건 변화에 따른 수관내부 약제 침투율 측정 실험을 통해 제안하는 모델의 효과성을 보였다. 실험결과, 무인항공기의높이가 지면과 가까울수록 작물에 고르게 살포되지만 안전이 고려된 2m이상이 높이와 평균 2m/s의 속도에서 가장방제효과가 적합하였다. 제안하는 방제 시스템은 농업환경에서의 다양한 무인항공기 활용 기반 지능형 서비스 개발에도움을 줄 것으로 기대한다.
Abstract
In the agricultural environment, pesticide control requires a high risk of work and a high labor force for farmers. The effectiveness of pesticide control using unmanned aerial vehicles varies according to climate, land type, and characteristics of unmanned aerial vehicles. Therefore, an effective method for pesticide control by unmanned aerial vehicles considering the spraying conditions and environmental conditions is required. In this paper, we propose an efficient pesticide control system based on agricultural unmanned aerial vehicles considering the application conditions and environmental information for each crop. The effectiveness of the proposed model was demonstrated by measuring the drop uniformity of pesticides according to the change in altitude and speed after attaching the sensory paper and measuring the penetration rate of the drug inside the canopy according to the change in crop growth conditions. Experiment result, the closer the height of the UAV is to the ground, the more evenly the crops are sprayed, but for safety reasons, 2m more is suitable, and on average a speed of 2m/s is most suitable for control. The proposed control system is expected to help develop intelligent services based on the use of various unmanned aerial vehicles in agricultural environments.
