The present invention relates to an unmanned aerial vehicle (UAV) for controlling pests and, more specifically, relates to an automatic change system for a UAV including a chemical container integrated with a battery, using a battery installed in a pesticide container storing a pesticide solution, detecting a state of the pesticide solution and the battery of the UAV, and automatically returning the UAV in time of requiring exchange to automatically change the pesticide container and the battery at the same time, so as to reduce a waiting time of the UAV thereby increasing a working efficiency. According to the present invention, the system comprises: the UAV including the pesticide container integrated with the battery to reduce a waiting time during the exchange so as to enhance user convenience and increase the working efficiency, detecting the state of the battery and the pesticide container, and automatically returning to a station in accordance with a detection result a landing part where the UAV is landed a landing guide device installed in the landing part to support landing of the UAV a UAV fixation plate to fixate the UAV a mounting part to automatically charge the battery and the pesticide container and an automatic exchange device to exchange the pesticide container integrated with the battery. Accordingly, since the integrated battery and pesticide container is automatically exchanged at one time, the user convenience of the UAV is enhanced and the UAV is able to continuously perform a mission thereby being able to reduce expenses and increase operation efficiency.COPYRIGHT KIPO 2017본 발명은 방제용 무인항공기에 관한 것으로, 더욱 상세하게는 방제용액이 저장되는 용기에 배터리가 설치되어 사용하며, 무인항공기의 방제용액 및 배터리의 상태를 감지하여 교환이 필요하면, 스테이션에 자동 복귀하여 방제용기와 배터리를 동시에 자동 교환함으로써 무인항공기의 대기시간을 감소시켜, 작업 효율을 높이는 것을 특징으로 하는 방제용기와 배터리를 일체형으로 갖춘 무인항공기의 자동교체시스템에 관한 것이다.본 발명에 의한 방제용기와 배터리를 일체형으로 갖춘 무인항공기의 자동교환시스템은 배터리와 방제용기가 일체형으로 구성되어 있어 교환 시에 대기시간을 감소시켜 사용자의 편의성을 향상시키고 작업 효율을 증대시키고, 또한 배터리와 방제용기의 상태를 감지하고 그 감지 결과에 따라
