Title:

UNMANNED AERIAL VEHICLE PROTECTIVE DEVICE AND METHOD, UNMANNED AERIAL VEHICLE AND FLIGHT FIELD

Document Type and Number:

WIPO Patent Application WO/2018/205099

Kind Code:

A1

Abstract:

An unmanned aerial vehicle protective device, comprising an index device (10) and a traction device (20) which are provided in a flight field; the traction device (20) comprises a pulley and a rope telescopic structure; the pulley is connected to the index device (10); the rope telescopic structure comprises a winding mechanism (21) and a traction rope (22); one end of the traction rope (22) is connected to an unmanned aerial vehicle (200), and the other end of the traction rope (22) is wound on the winding mechanism (21), wherein the winding mechanism (21) has a pre-tightening force acting on the traction rope (22); and when the pre-tightening force is greater than the tensile force to the traction rope (22) in the flight process of the unmanned aerial vehicle (200), the winding mechanism (21) automatically winds the traction rope (22). Also disclosed are a corresponding unmanned aerial vehicle protective method, an unmanned aerial vehicle and a flight field. According to the unmanned aerial vehicle protective device, the index device and the traction device in the flight field are matched with each other so that the traction rope can limit the unmanned aerial vehicle to fly within a preset flight region, and the length of the traction rope can be automatically adjusted according to the flight of the unmanned aerial vehicle, so as to ensure the safety of the unmanned aerial vehicle and personnel in the flight field.
