The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-falling, anti-collision and anti-lost device and method for a multi-rotor unmanned aerial vehicle. The device comprises an intelligent airbag module, a sound-light alarm module, a detection module and a control module, the detection module is connected with the control module and is used for acquiring upward speed, forward speed and angle information of the unmanned aerial vehicle; and the control module comprises a microcomputer processor and a GPS communication unit, and the GPS communication unit is electrically connected with the microcomputer processor. Different states and corresponding probabilities of the unmanned aerial vehicle can be judged, when the probability that the unmanned aerial vehicle is an accident is predicted to reach a preset value, an air bag in the device is automatically opened in advance, collision with an obstacle is buffered, the falling speed of the unmanned aerial vehicle is delayed, and the collision strength of the unmanned aerial vehicle can be reduced; buzzing and a warning lamp can enable a flying hand of the unmanned aerial vehicle to find a falling position more quickly, so that the searching difficulty is reduced; the device is provided with a GPS communication unit with an independent power supply, and it is ensured that the falling position can be determined after a positioning system of the unmanned aerial vehicle fails.

    本发明涉及无人机技术领域,为一种多旋翼无人机的防坠落撞毁防丢装置和方法。该装置包括智能气囊模块、声光报警模块、检测模块和控制模块;检测模块与控制模块连接,检测模块用来获取无人机的向上速度、前向速度和角度信息;控制模块,包括微机处理器和GPS通信单元,GPS通信单元和微机处理器电连接。本发明可以判断出无人机的不同状态和对应的概率,当预测出无人机为事故的概率达到预定值,自动提前打开装置中的气囊,缓冲与障碍物的碰撞,延缓无人机的坠落速度,都能减小其冲撞强度;蜂鸣声和警示灯能够让无人机飞手更快地寻找到坠落位置,降低搜寻难度;装置拥有独立电源的GPS通信单元,确保在无人机的定位系统失灵后,能够进行坠落位置的确定。
