Abstract

The invention relates to the technical field of unmanned aerial vehicle safety protection, and especially relates to an unmanned aerial vehicle safety protection method and device, and an unmanned aerial vehicle. The method includes obtaining the ultrasonic information and flight states of the unmanned aerial vehicle, wherein the flight states include a normal flight state and a descending state; and performing safety protection on the unmanned aerial vehicle according to the ultrasonic information and the flight states. The embodiments can reduce occurrence probability of high-altitude bombing of the unmanned aerial vehicle caused by the abnormity of ultrasound, unable descending, rising, left moving and right moving due to high-altitude out of control and violent ground hitting with non-decelerating landing, so that the safety of the unmanned aerial vehicle can be enhanced, and user experience can be improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of UAV safety protection, in particular to a method and device for UAV safety protection and UAV. [0003] 【Background technique】 [0004] When the UAV takes off and lands, the height to the ground is a key information. If the height to the ground is inaccurate, it will affect the take-off and landing performance of the UAV, especially the landing performance. At present, ultrasound is used to measure the height of the ground, and downward-looking ultrasonic radar is often used to sense the ground, so as to realize the safe take-off and landing of UAVs, as well as the normal flight of UAVs. [0005] However, ultrasound is easily disturbed and unstable, which is mainly manifested in the intermittent interruption or inaccurate measurement of ultrasonic data, and the occasional constant deceptive value of ultrasonic data, which may cause complete damage to the ultrasonic after the aircraft is aging or b...
