The present invention relates more specifically to a vibration-based bridge pier crack detection system using an unmanned aerial vehicle that can attach and detach a sensor module to a structure such as a bridge or a bridge pier using an unmanned aerial vehicle and perform vibration-based non-destructive inspection using the sensor module. The vibration-based bridge pier crack detection system using an unmanned aerial vehicle according to the present invention includes: an unmanned aerial vehicle that flies so as to be able to access a structure so as to attach one detachable sensor module to a sensor attachment location of the structure; a remote controller that wirelessly remotely controls the unmanned aerial vehicle; a detachable sensor module that is attached to the sensor attachment location so as to detect a crack in the structure, measures vibration information applied to the structure, and is then detached from the structure; a sensor attachment unit that is installed on the unmanned aerial vehicle and controlled by the remote controller and detaches the detachable sensor module from the structure; and a judgment unit that determines whether the structure is damaged based on the measured values from the detachable sensor module.

    본 발명은 더욱 상세하게는 교량이나 교각 등의 구조물에 무인비행체를 이용해 센서모듈을 탈부착하고, 센서모듈을 이용해 진동 기반의 비파괴 검사를 수행할 수 있는 무인비행체를 이용한 진동기반 교각 균열감지 시스템에 관한 것이다. 본 발명에 따른 무인비행체를 이용한 진동기반 교각 균열감지 시스템은하나의 탈부착 센서모듈을 구조물의 센서부착위치에 부착할 수 있도록 상기 구조물에 접근 가능하게 비행하는 무인비행체, 상기 무인비행체를 무선으로 원격 조종하는 조종기, 상기 구조물의 균열을 감지할 수 있도록 상기 센서부착위치에 부착되어 상기구조물에 가해지는 진동정보를 계측한 후, 상기 구조물로부터 탈착되는 탈부착 센서모듈, 상기 무인비행체에 설치되어 상기 조종기에 의해 제어되고, 상기 탈부착 센서모듈을 상기 구조물에 탈부착하는 센서부착유닛 및 상기 탈부착 센서모듈로부터 계측된 계측값에 따라 상기 구조물의 손상 여부를 판단하는 판단부를 포함한다.
