Airport unmanned aerial vehicle management and control area division method based on collision risks

Abstract

The invention provides a collision risk-based airport unmanned aerial vehicle management and control area division method, which comprises the following steps of S1, dividing a core area in a management and control area according to a collision risk probability e; S2, based on the management and control area inner core area, a management and control area buffer area corresponding to the managementand control area inner core area is divided; and S3, dividing an unmanned aerial vehicle control area, wherein the unmanned aerial vehicle control area is a union set of a control area inner core area and a control area buffer area. The method provided by the invention is an airport peripheral flight area classification and division method taking the unmanned aerial vehicle as an object for the first time in China, a nuclear area in a control area, a buffer area in the control area and a flyable area of the unmanned aerial vehicle are divided by utilizing the method, and technical support isprovided for related management provisions of the unmanned aerial vehicle. And the refined operation management of the unmanned aerial vehicle is realized on the premise of not influencing the operation safety and efficiency of the civil aircraft.

Description

technical field [0001] The invention relates to the technical field of air traffic control, in particular to the air operation management of unmanned aerial vehicles. Background technique [0002] Unmanned aerial vehicle (UAV) is an aircraft managed by a control station (including remote control or autonomous flight), also known as remotely piloted aircraft. Due to the characteristics of good mobility, high survivability, and strong overload capacity, UAVs have broad application prospects in logistics transportation, power line inspection, agriculture, forestry and plant protection, emergency rescue and disaster relief, and geographic surveying and mapping. [0003] However, while the civilian UAV market has been expanding in recent years, due to the fact that UAVs are easy to manufacture, easy to obtain, and have a wide range of users, there are also various risks hidden in the operation of UAVs. Among them, the most typical The biggest risk is to interfere with the normal...

Problems solved by technology

As a moving object, it is obviously unreasonable to apply the above-mentioned restriction range or protection range for stationary obstacles to control the flight activities of drones.

[0007] Secondly, the above-mentioned two types of schemes are fixed schemes for all runways, and lack of adaptation to the operating characteristics of different runways. The reasons are as follows: First, different runways correspond to completely different entry and departure procedures, and it may not be scientific to use a fixed scheme to adapt to different runways. Reasonable, the designation of UAV-controlled airspace should adapt to specific flight procedures

For example, as far as the current plan is concerned, the airport obstacle restriction surface is a symmetrical area on both sides of the runway. However, the aircraft takeoff and landing phase may not be along the direction of the runway, and may even be clearly biased to one side of the runway. The UAV control area should be combined with The actual operation situation is not necessarily symmetrical; the symmetrical UAV control area may cause the control area to be too large for the above-mentioned runway, thereby limiting the UAV flight area

Second, as far as the current plan is concerned, the arc radius of the tolerance buffer zone corresponding to all runways is 7070 meters, and there is no relevant basis for this fixed designation

In addition, a large number of studies assume that the flight error of the aircraft satisfies a fixed distribution within a flight segment, which is convenient for the calculation of collision risk assessment and has a certain loss in the accuracy of risk assessment
