The invention discloses a safe landing system and method of an unmanned aerial vehicle and the unmanned aerial vehicle, the safe landing system of the unmanned aerial vehicle comprises a sensor, a controller, a parachute and a safety air bag, because the parachute has a requirement for the height when the parachute is opened, when the height of the unmanned aerial vehicle is low, the parachute cannot be completely opened, and the safety air bag is opened; and a man-machine can hit the ground at a high speed, so that parts such as a fuselage, wings and propellers are damaged. And through protection of the safety air bag and the parachute, the unmanned aerial vehicle is protected against damage when the parachute cannot achieve the protection effect. The safe landing method of the unmanned aerial vehicle comprises the steps that when the unmanned aerial vehicle is unstable and the height is higher than a first preset height, the unmanned aerial vehicle has sufficient time to open a parachute, and at the moment, a controller controls opening of the parachute and closing of a power system of the unmanned aerial vehicle to reduce the falling speed of the unmanned aerial vehicle; when the unmanned aerial vehicle does not have enough time to completely open the parachute, the controller controls to open the safety air bag and close the power system of the unmanned aerial vehicle.

    本发明公开了一种无人机的安全降落系统、方法及无人机,无人机的安全降落系统,包括:传感器、控制器、降落伞和安全气囊,由于降落伞对开启时的高度有要求,在无人机高度较低时,降落伞无法完全打开,可能会导致人机以较高的速度撞击地面,导致机身、机翼、螺旋桨等部件的损坏。安全气囊和降落伞的保护,在降落伞无法起到防护作用时保护无人机免受损坏。无人机的安全降落方法为,无人机失稳时,高度高于第一预设高度,则无人机有充足时间打开降落伞,此时则控制器控制打开降落伞,关闭无人机的动力系统,以降低无人机下坠速度;但高度低于第一预设高度,无人机无充足时间完全打开降落伞,此时控制器控制打开安全气囊,关闭无人机的动力系统。
