Description

Technical Field

[0001] The present invention relates to the technical field of civil aviation airspace data processing, and in particular to a direction deconstruction method of a navigation plan report, and also to a direction deconstruction device of a navigation plan report. Background Art

[0002] With the rapid development of my country's civil aviation industry, the number of flights has increased year by year. In order to ensure the safety of aircraft and reduce flight delays, statistical analysis is conducted on indicators such as the number of take-offs and landings at various city airports, and the flow of waypoints and route segments in various regions in terms of time and space, so as to improve the utilization rate of airspace resources and provide technical support and auxiliary decision-making for airspace planning and management.

[0003] The Filed Flight Plan Message is a telegram sent by the air traffic service unit to all relevant air traffic service units along the route based on the flight plan data submitted by the aircraft operator or its agent. Group 15 represents the direction information of each flight, which includes waypoints and route information, but there is currently no research in China on deconstructing and generating point strings and route segment information. The direction information can be used to analyze indicators such as airport take-offs and landings, waypoint traffic, and route segment traffic, but the direction information of the flight plan report has the following problems:

[0004] 1. After important waypoints, there is information such as cruising speed or Mach number, applied cruising altitude layer, etc., and there are point-to-point direct connection marks such as "DCT", which cannot be directly identified.

[0005] 2. The direction is described by point routes, and the waypoints and route section information other than the turning points cannot be identified, so the direction cannot be used directly.

[0006] 3. The routes of international flights contain foreign waypoints and route information that cannot be fully identified.

[0007] 4. The direction information fails to match the data source to which it belongs, including Regulation No. 1, temporary seasonal changes, monthly temporary, temporary within the district, and others. Summary of the invention

[0008] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a method for deconstructing the direction of a navigation plan report, which can combine airspace resource information, deconstruct the direction of domestic flights and international flights, and convert it into quickly identifiable point route text descriptions, point strings, and route segment information, while matching the corresponding data sources to facilitate the query and statistics of multi-source data, and provide data support for the quantitative and objective evaluation of airspace resource utilization, thereby increasing the number of flights and tapping the potential of the airspace environment.

[0009] The technical solution of the present invention is: the direction deconstruction method of the pilot plan report comprises the following steps:

[0016] The WAYSEGMENT table identifies domestic waypoints or route information

[0017] If the border point is not specified in the route, the route table will be used to intercept the border point;

[0019] (4) Direction deconstruction: For the intercepted and identified navigation plan direction, the route in the direction is identified through the waypoint table WAYSEGMENT, and the two waypoints before and after the route in the direction are identified through the waypoint table POINT. The route segment information contained in the route is intercepted to obtain the point string and route segment information contained in the direction;

The matching data sources include the point string DBROUTE of No. 1 regulation, seasonal temporary, monthly temporary, and intra-district temporary, and the matching priority is set in this order.

[0080] The present invention is described in more detail below.

[0081] The deconstruction method of the flight plan report is divided into the analysis of domestic flight direction and the analysis of international flight direction. Domestic flights directly identify and split the waypoints and route information in the direction; international flights need to truncate the direction in advance and only retain the domestic part.

[0082] Take "Shanghai Hongqiao-Beijing Capital (ZSSS-ZBAA): PIKAS G330PIMOL A593 DPX / K0874S0920 A593 DALIM W157 AVBOX" for domestic flights as an example, and "Jakarta-Chengdu Tianfu (WIII-ZUTF): DCT DOLTA A585 PLB G579 PARDIDCT PU / N0458F360 B469 VPK M751 VKB M644 RYN N891BKK / N0464F370 W21 CMP R474 VTN B218SAGAG / K0870S1010 A581 SGM W144 IGNAK" for international flights as an example. The flight plan report direction table is shown in Table 1 below:

[0083] Table 1: Navigation plan report route table ROUTE

[0084]

[0085]

[0086] The specific steps are as follows:

[0087] Step 1: Determine whether it is a domestic flight or an international flight according to the airport table AIRPORT. The airport table is shown in Table 2 below:

[0088] Table 2: Airport table AIRPORT

[0089] name Four-character code Beijing / Capital ZB Shanghai / Hongqiao ZSSS Chengdu / Tianfu ZUTF ……

[0090] Step 2: Format the direction information and remove the information other than waypoints and routes. International flights need to intercept the domestic waypoints and routes of the direction through the waypoint table POINT and the route table WAYSEGMENT, and only keep the waypoints and routes in the two tables. The waypoint table is shown in Table 3 below:

[0091] Table 3: Waypoint table POINT

[0092] name Call Sign PIKAS Pi County DPX West Hill SGM ……

[0093] The route table is shown in Table 4 below:

[0094] Table 4: WAYSEGMENT

[0095]

[0096]

[0097] The trend is formatted as shown in Table 5 below:

[0098] Table 5: Towards formatting

[0099]

[0100] Step 3: Identify the waypoint through the waypoint table POINT, and convert the "call sign" description into the format of "waypoint Chinese name (call sign)", as shown in Table 6 below:

[0101] Table 6: Trend Identification

[0102]

[0103]

[0104] Step 4: Use the waypoint table POINT and route table WAYSEGMENT to describe the direction in the form of a point route, including the take-off and landing airports and the words "through" and "to". The starting point or end point of an international flight is represented by a border point;

[0105] Step 5: The route in the direction and the two waypoints before and after it are converted into point-to-point descriptions through the route table WAYSEGMENT. At the same time, the route segments are combined as "route-starting point-end point". Domestic flights are shown in Table 7 below, and international flights are shown in Table 8 below:

[0106] Table 7: Analysis of domestic flight routes

[0107]

[0108] Table 8: Analysis of routes for international flights

[0109]

[0110]

[0111] Step 6: Match the data source. If none of the four data sources can be matched, other data sources are used. The matching data source table is shown in Table 9 below:

[0112] Table 9: Matching data source table DATASOURCE

[0113]

[0114] Domestic flights, according to the point string parsed in step 5: [Shanghai / Hongqiao,PIKAS,UNTAN,PIMOL,

[0115] XUTGU,NIXEM,SUBKU,ATVAD,LAGAL,OMUDI,SAGIP,PIXian(DPX),UDINO,AVEPEP,OVTIT,

[0116] P86, P635, ABTUB, DALIM, TUMLO, P148, AGOGU, BUVMA, BEKDO, AVBOX, Beijing / Capital], and match the data source (No. 1 Regulation, seasonal temporary, monthly temporary, and district temporary) one by one, and find "Shanghai Hongqiao-Beijing Capital (ZSSS-ZBAA)" in No. 1 Regulation, and its point string: [Shanghai / Hongqiao, POMOK, XIREM, PIKAS, UNTAN, PIMOL, XUTGU, NIXEM, SUBKU, ATVAD, LAGAL, ​​OMUDI, SAGIP, Pi County (DPX),

[0117] UDINO,AVEPEP,OVTIT,P86,P635,ABTUB,DALIM,TUMLO,P148,AG OGU,BUVMA,BEKDO,

[0118] AVBOX, Beijing / Capital], the intersection of the two is the point string parsed in step 5, and is included in the point string specified by number 1.

[0119] For international flights, according to the point string parsed in step 5: [SAGAG, NOKET, BIDRU, ELASU, Xishan (SGM), DADOL, P334, Zhaotong (ZAT), OTBIM, ATPAV, VEDPO, KAKMI, IGNAK, Chengdu / Tianfu], match them one by one with the data source (No. 1 regulation, seasonal temporary, monthly temporary, intra-regional temporary), and find "Jakarta-Chengdu Tianfu (WIII-ZUTF)" in the seasonal temporary, and its point string: [SAGAG, NOKET, BIDRU, ELASU, Xishan (SGM), DADOL, P334, Zhaotong (ZAT), OTBIM, ATPAV, VEDPO, KAKMI, IGNAK, Chengdu / Tianfu]. The intersection of the two is the point string parsed in step 5, which is exactly the same as the point string of the seasonal temporary.

[0120] The specific results of each step are shown in Table 10 for domestic flights and Table 11 for international flights:

[0121] Table 10: Analysis of the trend of domestic flight pilot plan reports

[0122]

[0123]

[0124] Table 11: Analysis of the trend of international flight pilot plan reports

[0125]

[0126] The beneficial technical effects of the present invention are as follows:

[0127] Innovation: The data source information matched with the direction of each pilot plan report can intuitively reflect the number of flights executing multi-source data (No. 1 regulation, temporary seasonal changes, monthly temporary, temporary within the region, and others) every day, which is suitable for statistical research on related indicators.

[0128] Accuracy: The airport table, waypoint table and route table can accurately deconstruct the direction reported by the navigation plan, and at the same time determine whether there are irregularities or erroneous information in the direction.

[0129] Efficiency: The direction of each navigation plan report is decomposed into a string of points and route segment information. The flow of designated waypoints, routes, and route segments can be quickly queried according to different needs.

[0130] Convenience: Through the analysis of the waypoints, routes, and route segment flows after the deconstruction of the navigation plan report, the use of airspace resources can be discovered, providing auxiliary support for optimizing the airspace structure so that airspace resources can be effectively utilized.

[0131] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the protection scope of the technical solution of the present invention.
