A method of defining a flight area of an unmanned aerial vehicle based on a Beidou short message system and an unmanned aerial vehicle

Abstract

A method of defining a flight area of an unmanned aerial vehicle based on a Beidou short message system and an unmanned aerial vehicle are provided. The method comprises the steps of receiving a short message issued by a Beidou short message system, decrypting the short message to obtain no-fly information and realizing the temporary no-fly of the unmanned aerial vehicle according to the no-fly information. The beneficial effects of the present invention are that the method of defining the flight area of the unmanned aerial vehicle based on the Beidou short message system and the unmanned aerial vehicle are provided. By using the short message function provided by Beidou satellite in China, information such as no-fly area and no-fly time is sent through short messages; active no-fly intervention of the unmanned aerial vehicle is realized; a problem of impossibility of temporary no-fly of the unmanned aerial vehicle when temporary flight control is needed is solved; and spatial domain safety is better ensured.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle technology and the field of satellite communication, in particular to a method for restricting the flight of unmanned aerial vehicles in a limited area by using the short message function provided by my country's Beidou satellite, and can realize this method. approach to drones. Background technique [0002] With the rapid development of UAV technology, its flight performance, including endurance altitude and time, has become stronger and stronger, and the number of UAVs is also increasing. In order to ensure airspace security, according to the International Civil Aviation Organization and national air traffic control According to the regulations on airspace control and the management of drones, drones must fly in the specified airspace. For safety and responsibility considerations, drone manufacturers have added flight restriction functions in special areas to help users use products more s...

Problems solved by technology

[0003] However, we have found through research that this restriction function of drones has certain flaws in the design. At present, the flight restriction schemes of drone manufacturers mostly set a no-fly map in the aircraft before leaving the factory. The solution has two flaws. One is that the no-fly zone cannot be updated after the drone leaves the factory. When some areas are added as a no-fly zone, the no-fly zone will be invalid for the drones that have already been sold; Safety or special needs, when temporary flight control is required for a period of time, it is impossible to implement a temporary ban on drones
