example 1

[0145] Example 1: Demarcation of control areas under the runway departure procedure of an airport

[0146] Part of the flight segment corresponding to the runway departure procedure is a curve (there is a turn when the flight takes off). The corresponding flight segment in this example s ∈ [0, 10000] is:

[0147]

[0148]

[0149] z(s)=0.05s

[0150] This flight segment describes the turning angle along a circular arc with a radius of 6KM after take-off 2KM Then continue to fly in a straight line. In this example, the parameter of the collision risk zone can be taken as d l = d r = 283.887, d z = 133.5.

[0151] Suppose h = 120 meters, s 1 =10000 meters, at this moment, the boundary nplane(s of the inner core area of ​​the control area 2 ) corresponding parameter s 2 Satisfy:

[0152] z(s 2 )=h+d z =120+133.5=253.5

[0153] Since the gradient k=0.05 corresponding to the flight segment, so

example 2

[0187] Example 2: Designation of the control area under the approach procedure of an airport runway

[0188] This example gives an example of the instrument approach procedure of Chongqing Jiangbei Airport RWY02R, the flight is in the final approach segment is a straight line, and the horizontal velocity v can be known according to the information of the instrument approach chart x =93.05m / s, v y = 0m / s, v z =4.9m / s, the descent gradient of the aircraft during the approach phase is

[0189] flight segment s ∈ [0, 10000] satisfies the condition:

[0190] x(s)=s

[0191] y(s)=0

[0192] z(s)=k×s

[0193] Its collision risk zone parameter is d l = d r = 283.887, d z =129.615

[0194] Suppose h = 120 meters, s 1 =10000 meters, at this moment, the boundary nplane(s of the inner core area of ​​the control area 2 ) corresponding parameter s 2 Satisfy:

[0195] z(s 2 )=h+d z =120+129.615=249.615

[0196] Since the gradient k=0.0526 corresponding to the flight seg...

Abstract

The invention provides a collision risk-based unmanned aerial vehicle (UAV) control area buffer area division method for a flight route segment, which comprises the following steps of: S1, dividing acorresponding control area buffer area according to a core area in a control area; S2, the buffer area of the control area is the minimum area meeting the constraint condition; and S3, calculating toobtain parameters of the buffer area of the control area. By means of the division method, the control area buffer area can be set while the protection range of the nuclear area in the control area isaccurately controlled, it is ensured that accurate division of the civil unmanned aerial vehicle control area is achieved on the premise that the operation safety and efficiency of a civil aircraft are not affected, and refined operation management of the unmanned aerial vehicle is facilitated.

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] In recent years, while the scale of the civilian UAV market has continued to expand, 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 more typical risks are It interferes with the normal take-off and landing of flights at civil aviation airports. According to statistics, in the two years from 2015 to 2016 alone, there were as many as 27 incidents of civil drone interference in China. Since the vast majority of drones currently operate in ultra-low-altitude flight areas, civil aviation flights operate in the ultra-low-altitude airspace corresponding to the flight take-off and landing stage, that is, at this time, civil aviation flights are in the ultra-low...
