Description
Technical Field
The invention belongs to the technical field of civil aviation, and particularly relates to an ATC system-based airway analysis method and system.
Background
An Air Traffic Control automation System (ATC System) is the most important technical tool for an Air Traffic controller to grasp the Air flight situation in real time and implement Air Traffic Control.
The route along which an aircraft flies is called the airway. The route elements comprise route points, routes, special keywords and the like. The navigation points are divided into fixed points, longitude and latitude points and points represented by the position/distance of the important point;
1. the elements which can be searched from the fixed point basic database are fixed points;
2. points represented by longitude and latitude, such as 3804N10520E, are called longitude and latitude points;
3. points in the form of VYK060040 format represent significant point position/distance points;
VYK points where the magnetic orientation is 60 degrees and 40 nautical miles away are called important point orientation/distance points;
4. the element that can be matched from the name of the basic database of the airline is the airline. A course consists of a series of fixed points, and the adjacent elements of the course in the course information must generally be fixed points that make up the course to convert the course into a sequence of points.
5. The special keywords comprise DCT, VFR, IFR and T; what the DCT is connected must be is that two points that are not on the same route represent straight flights and VFR and IFR represent flight rule transitions.
6. Elements that are not identified (due to data missing, formatting errors) as belonging to any of the 5 types of elements are called unknown elements.
The course of the airway analysis is that the airway in the airway information is analyzed into a series of fixed points according to the basic data such as the fixed points, the airway and the like and the rules such as special points, keywords and the like, the segment of interest is intercepted according to the range of the control area, and the continuity of the segment of interest is checked.
For example, the following steps are carried out: the route W1 is composed of points P1P 2P 3P 4, the route W2 is composed of points P3P 6P 7P 8, the route information is P1W 1P 3W 2P 7, and the route is analyzed into a point sequence P1P 2P 3P 6P 7. Assuming that the regulatory region only cares about P6, the final analysis result is P1P 2P 3P 6.
According to the traditional route analysis, routes are sequentially expanded from left to right according to configured fixed points and route basic data according to a point-route-point route composition basic rule, unknown route elements and routes which cannot be expanded according to the route basic data are directly ignored, after the whole route is analyzed into points, route points near a controlled area are reserved according to the range of the controlled area, and the rest route points are discarded.
The conventional techniques have the following disadvantages: 1) maintenance work of basic data of the air route is more; 2) the airway continuity check is not critical.
The reasons for the disadvantages are: 1) the traditional technology analyzes the whole route according to the point-route-point rule, seriously depends on the integrity of route data, and needs active maintenance even if the changed part is far away from the control area when the data of a long route is changed; 2) unknown airway elements and airways which cannot be unfolded are directly discarded, and effective prompt for controllers is difficult to be given to discontinuities of the airways.

Step S2, classifying the route elements of the initial route, the route elements including:
(1) an airport;
(2) point: fixed points, latitude and longitude points (points represented by point position/distance are converted into latitude and longitude points);

In this embodiment, only the route information between the first route element (starting route element) and the last route element (ending route element) concerned by the regulatory region unit is reserved, and all route information except the concerned route is discarded. Two regions are first defined:
(1) a control area: the AOR is the actual jurisdiction range of a control area unit;
(2) the region of interest: the AOI is an external expansion area of the AOR area and is an area range concerned by a control area unit.
FIG. 2 is a schematic diagram of the AOR and AOI regions.
The method for positioning the initial route element comprises the following specific steps:
if the takeoff airport is in the AOI, the takeoff airport is an initial route element;
if the takeoff airport is outside the AOI, sequentially searching a first AOR inner point in the route (the isolated point needs to be ignored, namely the adjacent elements of the point are unknown), after the AOR inner point is found, reversely searching route elements, preferentially searching a first AOI outer point in the reverse searching process, searching a first route if the first AOI outer point does not exist, searching a last point if the first route does not exist, and stopping if the unknown elements are met in the searching process, thereby obtaining an initial route element.
And after the initial route element is positioned, discarding all route information in front of the initial route element, and replacing with an 'x' to indicate that a discarded route exists.
The method comprises the following specific steps of:
if the landing airport is in the AOI, the landing airport is an element for ending the route;
if the landing airport is outside the AOI, reversely searching a first AOR inner point in the route (the isolated point needs to be ignored, namely the adjacent elements of the point are unknown), and after the AOR inner point is found, sequentially searching route elements, preferentially searching a first AOI outer point in the sequential searching process, searching a first route if the first AOI outer point does not exist, searching a last point if the first route does not exist, and stopping if the unknown element is met in the searching process, thereby obtaining an end route element.
And after the ending route element is positioned, discarding all route information after the ending route element, and replacing with an 'X' to indicate that a discarded route exists.
In this embodiment, if the AOR interior point is not found in the process of locating the start-end element, it is prompted that the route does not pass through the local regulatory area unit.
Taking an airline flight of Wuluquine (ZWWW) -Guangzhou (ZGGG) as an example, the initial route is as follows:
P0 W0 P1 W1 P2 W2 P3 W3 P4 W4 P5 W5 P6 W6 P7 W7 P8 DCT P9 W9 P99；
wherein P is point, W is course, P1, P8 are AOR interior points, P0, W0, W9, P99 have no basic data. After positioning and extraction, obtaining the concerned airway of the control area unit as follows:
**P1 W1 P2 W2 P3 W3 P4 W4 P5 W5 P6 W6 P7 W7 P8 DCT P9**。
step S4, performing continuity and validity detection on the concerned route based on the category of the route element to obtain a plurality of segmented valid route segments, specifically:
checking the continuity of adjacent route elements in the concerned route, and adding discontinuous marks between the discontinuous adjacent route elements;
examining unknown elements in the concerned route;
and (4) dividing the concerned airway by using the discontinuous marks and unknown elements to obtain a plurality of divided segments.
Respectively unfolding the plurality of flight sections to obtain a plurality of unfolded flight sections;
and respectively carrying out validity detection on the plurality of unfolded voyage sections according to validity detection rules, thereby obtaining a plurality of valid voyage sections.
In the present embodiment, a discontinuity mark "+" is added between two adjacent route elements constituting the route of interest to indicate a discontinuity if the following is true:
a) both elements are air lines;
b) one of the elements is a course, but the other element is not on the course;
c) the previous element is a DCT, but the next element is not a point;
d) both elements are points, but the two points are not on the same course;
e) the previous element is not a dot, but the next element is IFR/VFR.
In this embodiment, the concerned route is divided by the discontinuous flag "+" and the unknown element, for example, the discontinuous flag "+" and the unknown element are marked with red to prompt interruption of the concerned route, and the concerned route is divided to obtain a plurality of divided route segments. The segmented leg results are as follows:
in this embodiment, before validity detection is performed, each leg needs to be expanded. Expanding complete points, namely route points according to route data; if the first element is a route, a route-point is unfolded according to the route direction data, and the route is abandoned if the direction is not configured; if the tail element is a flight path, a point-flight path is unfolded according to flight path direction data, and if the direction is not configured, the flight path is discarded. The route direction configuration table is as follows:
note: the course direction is determined by any two fixed points on the course in sequence. The course direction is used for analyzing the course which can not be cut in a point-line-point mode. Typically, routes that cross the AOI boundary need to be configured.
For example, W2 includes waypoints P21P 22P 3P 23P 24, W3 includes waypoints P30P 3P 31P 32P 4, W7 includes waypoints P77P 7P 71P 72P 8P 81; the concerned route is divided into 5 segments, wherein W1, W4, W5 and W6 cannot be unfolded in the non-course direction, and the unfolding result of each segment is as follows:
a flight segment 1: P1W 1 is deployed as: p1
And (3) a flight section 2: W2P 3W 3P 4 is unfolded: P21P 22P 3P 31P 32P 33P 4
And (3) a flight section: P5W 5 is deployed as: p5
And 4, a flight section: P6W 6 is deployed as: p6
And (5) a flight section: P7W 7P 8 DCT P9 is expanded into: P7P 71P 72P 8 DCT P9
And after obtaining a plurality of flight segments, carrying out validity detection on each flight segment. The validity detection rule (i.e. each leg needs to satisfy the following conditions) is as follows:
1) the next point at the takeoff airport must be the airport corridor entrance point;
2) the former point of the destination airport must be an airport corridor entrance point;
3) the method comprises the steps that complete AOR entering boundary points and complete AOR exiting boundary points are required, and the entering boundary points and the exiting boundary points can be obtained through calculation;
4) at least one point before entering the AOR boundary point;
5) at least one point is located after the AOR boundary point.
The method for calculating the boundary point comprises the following steps:
a. the first point is the airport and within AOR the take-off airport is the AOR in-bound point
b. If a point is not an airport but within the AOR, then no AOR enters the boundary point;
c. the first point is outside the AOR, and the intersection point of the connecting line of adjacent points crossing the AOR boundary and the AOR boundary needs to be calculated.
i. If the distance between the two points of the intersection point exceeds S (parameter) kilometer, no AOR enters the boundary point; unless DCT connects two points, the intersection point is the boundary point;
ii. If the distance from one point is within S kilometers, the point is a boundary entering point;
iii, if the distances are within S kilometers, if no predefined AOR boundary point exists, the first route point of the route section is an entering boundary point; if one of the boundary points is predefined AOR, the point is a boundary point; if the AOR boundary point is predefined by two points, the first route point of the segment is the entering boundary point.
The method for calculating the boundary point comprises the following steps:
a. the last point is an airport and within the AOR, the destination airport is the AOR out-of-boundary point;
b. if the last point is not an airport but is within the AOR, no AOR goes out of the boundary point;
c. and calculating the intersection point of the connecting line of the adjacent points crossing the AOR boundary and the AOR boundary from the next point of the boundary point.
i. If the distance between the two points of the intersection point exceeds S (parameter) kilometer, no AOR goes out of the boundary point; unless DCT connects two points, the intersection point is the boundary point;
ii. If the distance from one point is within S kilometers, the point is a boundary point;
iii, if the distances are within S kilometers, if no predefined AOR boundary point exists, the tail route point of the segment is taken as an exit boundary point; if one of the boundary points is predefined AOR, the point is an out boundary point; and if the AOR boundary point is predefined by the two points, the tail route point of the segment is the out-boundary point.
In this embodiment, after validity detection is performed on a plurality of flight segments, an effective flight segment is obtained, an ineffective flight segment is labeled (for example, yellow label is marked), and a flight segment concerned after continuity detection and validity detection is as follows:
as indicated above, leg 1, leg 3, and leg 4 are inactive legs, and leg 2 and leg 5 are active legs. The detection result needs to be presented to a controller, and the discontinuity of the air route and the invalid air section can be quickly positioned, so that the controller can conveniently correct the discontinuity.
And step S5, after the effective flight segments are obtained, optimizing and combining the effective flight segments.
Firstly, optimizing an effective flight segment, removing redundant elements, and providing an interested part:
1) if the navigation section has an AOI outer point before entering the AOR, only the last AOI outer point before entering the AOR is reserved;
2) and after the navigation road section goes out of the AOR, the AOI outer point is arranged, and only the first AOI outer point after the AOR is reserved.
Redundant points are removed through the two modes, and therefore the optimized effective flight section is obtained.
And then merging the optimized effective flight segments.
At least one effective flight segment is considered to be effective for the whole route, otherwise, the route is prompted to be ineffective. If a plurality of effective legs exist, the optimized effective legs are connected by the star points, and multiple entering and exiting of the controlled area are represented. And finally, optimizing and combining the analysis results as follows:
P21 P22 P3 P31 P32 P33**P7 P71 P72 P8 DCT P9。
as shown in fig. 4, the area of the merged effective route on AOR and AOI is schematically illustrated. Note that when the ATC system interface displays that the flight is predicted to fly over the route, the points on both sides of "+" need to be connected by special lines to prompt the control of the discontinuous route. On the area schematic diagrams of AOR and AOI, the controller can see the optimized and combined effective airway, so that the controller can conveniently check and correct.
In summary, the technical solution of the present embodiment has the following beneficial effects:
1) one section of air route concerned by the control area can be screened out for analysis, the analysis and continuity detection of the whole air route are not needed, and only the air route and the air route point data near the control area are needed to be maintained.
