UNMANNED FLIGHT VEHICLE AND FLIGHT SYSTEM

PROBLEM TO BE SOLVED: To provide an unmanned flight vehicle which obtains a suitable image according to a construction state of an electric wire while maintaining a constant distance from the electric wire, and a flight system.SOLUTION: An unmanned flight vehicle 10, which flies along an electric wire C while maintaining a prescribed distance from the electric wire C based on a magnitude of electric current which flows through the electric wire C, comprises: an antenna 102 through which induction current A flows by receiving magnetic flux G which is generated by electric current which flows through the electric wire C; a GPS receiver which receives a GPS signal; an imaging unit 105 for imaging the electric wire C; an image transmission unit which transmits an image picked up by the imaging unit 105 to the exterior; and a control unit which so controls flight motion as to be along a flight path which has been predetermined along the electric wire C based on the received GPS signal, and so controls flight motion as to maintain a constant distance from the electric wire C based on a magnitude of the induction current A which flows through the antenna 102.SELECTED DRAWING: Figure 4 【課題】電線から一定の距離を保ちつつ、電線の架設状況に応じた好適な画像を得る無人飛行体及び飛行システムを提供する。【解決手段】電線Ｃを流れる電流の大きさに基づいて電線Ｃと所定の距離を保ちつつ電線Ｃに沿って飛行する無人飛行体１０であって、電線Ｃを流れる電流が生成する磁束Ｇを受信することにより誘導電流Ａが流れるアンテナ１０２と、ＧＰＳ信号を受信するＧＰＳ受信器と、電線Ｃを撮像するための撮像部１０５と、前記撮像部１０５によって撮像された画像を外部に送信する画像送信部と、受信したＧＰＳ信号に基づいて電線Ｃに沿って予め定められた飛行経路に沿うように飛行動作を制御するとともに、前記アンテナ１０２に流れる誘導電流Ａの大きさに基づいて、電線Ｃとの距離を一定に保つように飛行動作を制御する制御部と、を備える。【選択図】図４
