The invention discloses an unmanned aerial vehicle falling-into-water guiding and searching method, and relates to the technical field of unmanned aerial vehicle safety protection, and the specific method is as follows: a carbon fiber barrel is screwed on an unmanned aerial vehicle, a position indicator is embedded in a semi-floating ball, a Kevlar rope is arranged in a fire wall, one end of the Kevlar rope is tied on the unmanned aerial vehicle, the other end of the Kevlar rope is tied on the semi-floating ball, and nitrocotton is laid on an igniter; and the semi-floating ball and the carbon fiber barrel are tightly plugged through a water-soluble film. The key switch is pressed down before the unmanned aerial vehicle takes off, the controller is powered on (the logic that the attitude angle is larger than or equal to +/-60 degrees for ignition is preset), when the unmanned aerial vehicle falls in danger, the igniter ignites the nitrocotton, the semi-floating ball is ejected instantly, and the semi-floating ball is released actively. If the method fails, the water-soluble film is dissolved within 5 seconds when the semi-floating ball enters the water, and the semi-floating ball automatically emerges from the water surface under the action of buoyancy, namely the semi-floating ball is passively released. The method helps to improve the searching efficiency and success rate after the unmanned aerial vehicle falls into water, and reduces the salvage difficulty and cost at the same time.
本发明公开了一种无人机落水引搜方法,涉及无人机安全防护技术领域,具体方法是:碳纤桶螺接于无人机上,将示位器嵌于半浮球内,凯夫拉绳置于隔火墙内,一头系在无人机上,另一头系在半浮球上,硝化棉铺在点火器之上,半浮球与碳纤桶之间通过水溶膜填缝塞紧。起飞前按下按键开关,控制器上电(预设了姿态角≥±60°点火的逻辑),当无人机遇险坠落时,点火器点燃硝化棉,瞬间将半浮球弹出,即主动释放半浮球。如果上述方法失效,在入水5秒内,水溶膜溶解,半浮球在浮力作用下自动浮出水面,即被动释放半浮球。本方法有助于提高无人机落水后搜寻效率和成功率,同时降低打捞难度和成本。
