Description

Technical Field

[0001] The present invention relates to the field of rapid drawing of flight tracks and protection zones and their application, and in particular to a method and system for rapid drawing of flight tracks and protection zones in a terminal area based on ARINC424. Background Art

[0002] With the steady growth of social demand, the improvement of economic level and the increase in electricity demand from various sectors of society, the key points of power grid construction are also increasing. High-voltage transmission lines are equivalent to the skeleton of my country's power grid. In the process of high-voltage transmission line design, the influence of existing project facilities and environmental factors in the surrounding area should be fully considered. In particular, high-voltage lines pass near airports, and their lines may have an impact on airport operations. In recent years, there have been continuous cases of super-high transmission and transformation lines around airports, which have caused damage to the airport's clear air environment and endangered flight safety. The Civil Aviation Administration issued documents on clear air management and carried out investigations and rectifications. It is required to relocate and rebuild super-high transmission and transformation lines to meet the requirements of clear air management. In order to ensure the safe operation of civil aviation airports, the Civil Aviation Administration has successively issued laws, regulations, rules, standards and normative documents such as the "Civil Airport Management Regulations", "Civil Aviation Airport Operation Minimum Standards Formulation and Implementation Guidelines" (AC-97-FS-2011-01), "Civil Airport Operation Safety Management Regulations", "Civil Airport Airfield Technical Standards" (MH5001-2021) and "Transport Airport Clearance Review Management Measures for Construction Projects in the Clearance Area" (Civil Aviation Regulations (2021) No. 3)), which put forward clear requirements for airport clearance management and safe operation. If the high-voltage line planning scheme enters the airport clearance area, the opinions of the civil aviation department shall be sought.

[0003] Because electricity and civil aviation belong to two different industries, the power system design department cannot grasp the situation of civil aviation airports in a timely and accurate manner. At the same time, with the development of my country's civil aviation transportation industry, there are more and more airports with larger clear areas, and power transmission line planning often enters the clear areas of airports; this will lead to the situation that power design and laying will face the situation of entering the clear area and being demolished. At present, in the work of impact assessment of flight procedures and operating standards, usually, power assessment personnel need to manually analyze the flight procedures and their protection areas based on the charts published by the airport. Due to the high threshold for drawing civil aviation flight procedures, it is difficult to conduct an intuitive inspection of whether there is an impact on civil aviation flight procedures. ARINC424 code (ARINC424 navigation specification format uniformly adopts 132-bit plain text record, and various navigation database elements are encoded according to fixed regulations format, from 1 to 132 bits, using each number of bits to define a specific attribute of a certain aviation element, and the data is automatically updated regularly every 28 days. The use of ARINC424 data can timely grasp the latest basic navigation data; however, relying solely on ARINC424 cannot accurately restore the corresponding flight track, and without an accurate track, it is impossible to draw the correct protection area) is the data format and code of the airborne navigation database. It is the main information source and important basis for the flight control of the aircraft flight management system (FMS) and the automatic flight control system (AFCS), and is one of the important links to ensure the safety of aircraft operation. ARINC424 code contains information such as path termination code, positioning point, magnetic track / heading, turning direction, altitude, speed, navigation accuracy, airport, runway, navigation station, waypoint, approach and departure and approach flight procedures. How to quickly draw flight tracks and protection areas based on ARINC424 data and in combination with other data, and then evaluate and implement flight protection areas (or clear areas) for the airport area and nearby power facilities, is a technical problem that needs to be solved in the design and evaluation of power facilities around the airport. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problem that the current design and evaluation of power facilities only rely on power personnel and cannot quickly obtain flight tracks and protection areas, resulting in unreasonable planning of power transmission lines, and to provide a method and system for quickly drawing flight tracks and protection areas based on ARINC424 terminal areas.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A method for quickly drawing flight tracks and protection areas in a terminal area based on ARINC424, the method comprising:

[0007] S1. Collect the original text format ARINC424 data, parse and process it, and store it as the original ARINC424 terminal area database. The original ARINC424 terminal area database includes airport data, runway data, navigation station data, waypoint data and flight procedure data. The airport data includes the airport code, airport name, airport reference point coordinates, airport elevation, magnetic variation, transition altitude and transition altitude layer.

The navigation station data includes the navigation station code, navigation station name, airport, navigation station type, navigation station longitude and latitude, frequency and call sign, magnetic variation, and elevation of the location. The waypoint data includes the waypoint code, waypoint name, airport, waypoint type, longitude and latitude, and magnetic variation. The flight procedure data includes the path termination code, positioning point identification, whether to fly over, magnetic heading, turn indication, altitude and altitude type, speed limit, vertical path angle VPA / overfly runway threshold height TCH, navigation performance, airport, number of approach and departure procedures, and waiting time; the NAIP data of the navigation information compilation is collected and the operation and graphic key information database is obtained according to the field rules of the ARINC424 data. The operation and graphic key information database includes the airport, number of approach and departure procedures, climb gradient of the departure segment, whether the departure designated altitude turning procedure prohibits turning before the runway liftoff end, and whether the approach designated altitude missed approach procedure prohibits turning before the missed approach point; the original ARINC424 terminal area database is fused with the operation and graphic key information database to obtain the improved ARINC424 terminal area database;

[0008] S2. Identify the flight track termination code of the improved ARINC424 terminal area database and divide the flight track, extract key parameters including runway elevation, distance L from the turning point to the runway DER, turning point altitude H, indicated airspeed IAS, turning slope α, turning point positioning tolerance, and calculate as follows:

[0009] True air speed TAS: TAS = K × IAS, where K is the speed conversion parameter, K = 171233 × [(288 + VAR) - 0.006496H] 0.5 ÷(288-0.006496H) 2.628 ;

[0010] Turn rate R:

[0011] Turning radius r:

[0012] The influence of wind θ : E θis the value affected by the wind after turning at an angle of θ;

[0013] S3, construct a flight track and protection zone drawing model, the flight track and protection zone drawing model has a coordinate system containing latitude and longitude information, extract data from the improved ARINC424 terminal area database to draw the runway and airport on the coordinate system, and then draw the runway near-end straight segment track on the coordinate system based on the distance L from the turning point to the runway DER, and draw a turning arc at the end of the runway near-end straight segment track on the coordinate system according to the turning radius r; identify the turning end point of the flight track, draw the straight segment track after the turn according to the turning end point and the tangent of the turning arc, thereby obtaining the track containing the turn, and draw other tracks in sequence to obtain the flight track;

[0014] The flight track and protection zone drawing model draws the protection zone on the coordinate system based on the runway and the flight track, and the flight track and protection zone drawing model outputs the flight track drawing data and the protection zone drawing data.

[0015] In order to better realize the present invention (applying the flight track drawing data and protection zone drawing data of the present invention to the evaluation of the laying of airport power facilities), the present invention also includes the following method:

[0016] S4. Use flight track drawing data and protection zone drawing data to conduct planning and evaluation of airport power facilities, including power transmission lines.

[0017] Preferably, the coordinate system inside the flight track and protection area drawing model is a three-dimensional coordinate system, in which the X-axis and the Y-axis represent the latitude and longitude data respectively, and the Z-axis represents the elevation data.

[0018] Preferably, in step S3, the flight track and protection zone drawing model uses departure data to draw the flight track and protection zone.

[0019] Preferably, before drawing the protection zone, the flight track and protection zone drawing model retrieves information from the operation and graphic key information database on whether the departure designated altitude turning procedure prohibits turning before the runway DER. If the information is yes, the protection zone boundary line is drawn 150 meters to the side of the runway DER; if the information is no, the protection zone boundary line is drawn 600 meters inside and 150 meters to the side of the runway entrance.

[0020] Preferably, the half width of the protected area at the runway DER in the protected area is 150 meters, and then it is expanded at an expansion angle of 15°; the distance L from the turning point to the runway DER is the earliest turning point KK' line; the latest turning point = L + tolerance C, tolerance C: C = (TAS + W) × (t 飞行员反应时间 +t 建立坡度时间); The wind spiral is drawn from both sides of the latest turning point, and the two wind spirals are connected by a common tangent; the boundary of the upper latest turning track protection zone is the connection between the turning end point and the tangent of the outer boundary of the wind spiral, and it is extended 15° outward and tangent to the half width of the protection zone; the boundary of the lower earliest turning track protection zone is the connection between the turning end point and the position 150 meters to the side of the runway DER or 600 meters inside and 150 meters to the side of the runway entrance.

[0021] Preferably, the improved ARINC424 terminal area database is identified as to whether the departure is made by turning at a specified altitude or by turning at a specified point. If the departure is made by turning at a specified altitude, the distance L from the turning point to the runway DER is equal to the altitude of the turning point / the climb gradient of the departure straight section. The altitude of the turning point is read from the flight procedure data, and the climb gradient of the departure straight section is read from the operation and graphic key information data. If the departure is made by turning at a specified point, the distance L from the turning point to the runway DER is calculated by calculating the distance based on the longitude and latitude of the turning point and the longitude and latitude of the runway DER. The longitude and latitude of the turning point are read from the waypoint data, and the longitude and latitude of the runway DER are read from the runway data.

[0022] A fast drawing system for flight track and protection area based on ARINC424 terminal area includes a database construction system and a flight track and protection area drawing model. The database construction system has an original ARINC424 terminal area database, an operation and graphic key information database and an improved ARINC424 terminal area database. The improved ARINC424 terminal area database is obtained by data fusion processing of the original ARINC424 terminal area database and the operation and graphic key information database. The original ARINC424 terminal area database is obtained by parsing and storing the original text format ARINC424 data. The operation and graphic key information database is a navigation information compilation NAIP data. The flight track and protection zone drawing model includes a key parameter extraction and calculation module, a flight track drawing module and a protection zone drawing module, and the flight track and protection zone drawing model has a coordinate system inside; the key parameter extraction and calculation module is used to identify the flight track termination code of the improved ARINC424 terminal area database and perform flight track division, extract key parameters including runway elevation, distance L from the turning point to the runway, turning point altitude H, indicated airspeed IAS, turning slope α, and turning point positioning tolerance in the flight track, and the key parameter extraction and calculation module calculates the true airspeed TAS, turning rate R, turning radius r, wind impact E θThe flight track drawing module draws the runway and the airport on the coordinate system, draws the runway proximal straight segment track on the coordinate system based on the distance L from the turning point to the runway DER, draws a turning arc at the end of the runway proximal straight segment track on the coordinate system according to the turning radius r, identifies the turning end point of the flight track, draws the straight segment track after the turn according to the turning end point and the tangent of the turning arc, thereby obtaining a track including the turn, and draws other tracks in sequence to obtain the flight track; the protection zone drawing module draws the protection zone on the coordinate system; the flight track and protection zone drawing model is also used to output the flight track drawing data and the protection zone drawing data to the outside.

[0032] The present invention is further described in detail below in conjunction with embodiments:

[0033] Example

[0034] like Figure 1 As shown, a method for quickly drawing a flight track and a protection zone in a terminal area based on ARINC424 is provided, and the method includes:

[0035] S1. Collect the original text format ARINC424 data, parse and process it according to the 132-bit encoding rule, and store it as the original ARINC424 terminal area database. The original ARINC424 terminal area database includes airport data, runway data, navigation station data, waypoint data and flight procedure data. The data in the original ARINC424 terminal area database is preferably stored in an Excel data format that can be read, viewed and edited; the airport data includes the airport code, airport name, airport reference point coordinates, airport elevation, magnetic variation, transition altitude and transition altitude layer, and the runway data includes the airport, runway number, runway length and width , runway magnetic bearing, latitude and longitude coordinates and elevation of runway entrance point, maximum aircraft type that can be used, navigation station data including navigation station code, navigation station name, airport, navigation station type, navigation station longitude and latitude, frequency and call sign, magnetic variation, elevation of the location, waypoint data including waypoint code, waypoint name, airport, waypoint type, longitude and latitude and magnetic variation, flight procedure data including path end code, positioning point identification, whether to fly over, magnetic heading, turn instructions, altitude and altitude type, speed limit, vertical path angle VPA / runway threshold height TCH, navigation performance, airport, arrival, departure and approach procedure numbers, and waiting time. The NAIP data collected from the navigation data compilation is obtained according to the field rules of the ARINC424 data to obtain the operation and graphics key information database. The data of the operation and graphics key information database is preferably stored in the Excel data format that can be read, viewed and edited; the operation and graphics key information database includes the airport, the number of the approach procedure, the departure segment climb gradient, whether the departure designated altitude turn procedure prohibits turning before the runway liftoff end, and whether the approach designated altitude go-around procedure prohibits turning before the go-around point. The original ARINC424 terminal area database and the operation and graphics key information database are fused to obtain the improved ARINC424 terminal area database; the improved ARINC424 terminal area database includes all column information including the original ARINC424 terminal area database and the operation and graphics key information database, and is also stored in the Excel data format that can be read, viewed and edited.

[0036] S2. Identify the flight track termination code of the improved ARINC424 terminal area database and divide the flight track, extract key parameters including runway elevation, distance L from the turning point to the runway DER, turning point altitude H, indicated airspeed IAS, turning slope α, turning point positioning tolerance, and calculate as follows:

[0037] True air speed TAS: TAS = K × IAS, where K is the speed conversion parameter, K = 171233 × [(288 + VAR) - 0.006496H] 0.5 ÷(288-0.006496H) 2.628 ; VAR is the temperature difference relative to the International Standard Atmosphere (ISA), and is usually taken as 15 in program design; H is the altitude of the turning point in meters; the true airspeed TAS is in meters per second (m / s).

[0038] Turn rate R: The turning rate is the angle turned per unit time, measured in degrees per second (° / s).

[0039] Turning radius r: The turning radius is in meters.

[0040] The influence of wind θ : E θ is the value affected by the wind after rotating through an angle of θ.

[0041] Turning slope α: The tilt angle of the aircraft when turning, that is, the angle between the horizontal axis of the aircraft and the horizon or the vertical axis of the aircraft and the vertical line of the ground is called the turning slope (α), and the unit is degree (°). The turning slope value of 15° specified by regulations is usually used in the departure procedure design process.

[0042] C tolerance: C = (TAS + W) × (t 飞行员反应时间 +t 建立坡度时间 ); W is the wind speed. In the departure flight procedure design, W usually uses the fixed value of 15.56m / s specified by regulations. The pilot reaction time and the slope establishment time are both 3 seconds.

[0043] Turning point positioning tolerance: The positioning tolerance of the PBN departure procedure is a fixed value specified by regulations; the positioning tolerance of the traditional departure procedure = 460 + distance from the DME navigation station * 0.0125.

[0044] The improved ARINC424 terminal area database is identified and processed to determine whether to use a designated altitude turning departure or a designated point turning departure. If a designated altitude turning departure is used, the turning point altitude H uses the published design value (read from the flight procedure data). If a designated point turning departure is used, the turning point altitude H=h+L*10%, where h is the runway DER elevation and L is the distance from the turning point to the runway DER.

[0045] S3. Construct a flight track and protection zone drawing model. The flight track and protection zone drawing model has a coordinate system containing longitude and latitude information (the coordinate system can be two-dimensional or three-dimensional. Preferably, the coordinate system inside the flight track and protection zone drawing model is a three-dimensional coordinate system, in which the X-axis and Y-axis represent longitude and latitude data, respectively, and the Z-axis represents elevation data). Extract data from the improved ARINC424 terminal area database (preferably, the flight track and protection zone drawing model uses departure data to draw the flight track and protection zone) to draw the runway and airport on the coordinate system. Then, based on the distance L from the turning point to the runway DER, draw the runway proximal straight segment track on the coordinate system. Draw a turning arc at the end of the runway proximal straight segment track on the coordinate system according to the turning radius r. Identify the turning end point of the flight track, draw the straight segment track after the turn according to the tangent of the turning end point and the turning arc, thereby obtaining a track containing the turn, and draw other tracks in sequence to obtain the flight track ( Figure 4 exemplifies a flight path for a departure). In some embodiments, Figure 3 A simple method for constructing a two-dimensional coordinate system is shown. The coordinate system takes the runway DER as the center, the runway direction as the positive direction of the X-axis, and the right-hand rule is used to determine the positive direction of the Y-axis to construct a simple two-dimensional coordinate system.

[0046] The flight track and protection zone drawing model draws the protection zone on the coordinate system based on the runway, flight track, airspace protection zone and airport operation standards. The flight track and protection zone drawing model outputs the flight track drawing data and the protection zone drawing data. Preferably, the flight track drawing data and the protection zone drawing data are .dwg files that can be read by CAD (dwg files can be edited and modified).

[0047] When using it, you can select the track segments of the airport's approach and departure procedures to be exported, and they can be exported separately as .dwg files that can be read by CAD (dwg files can be edited and modified). All the approach and departure procedures of the selected airport can be packaged and exported as one dwg file, and different approach and departure procedures are saved in different CAD layers according to the approach and departure procedure numbers; different procedures can be stored in different layers.

[0048] In some embodiments, before drawing the protection zone, the flight track and protection zone drawing model retrieves information from the operation and graphic key information database to determine whether the departure designated altitude turning procedure prohibits turning before the runway DER. If the information is yes, the protection zone boundary line is drawn 150 meters to the side of the runway DER. If the information is no, the protection zone boundary line is drawn 600 meters inside the runway entrance and 150 meters to the side.

[0049] In some embodiments, the method of drawing the flight track and protection zone model when drawing the protection zone is as follows: Figure 5 , Figure 6 As shown in the figure, the half width of the protected area at the runway DER in the protected area is 150 meters, and then it expands at a 15° expansion angle. The distance L between the turning point and the runway DER is the earliest turning point KK' line. The latest turning point = L + tolerance C, tolerance C: C = (TAS + W) × (t 飞行员反应时间 +t 建立坡度时间 The wind spiral is drawn from both sides of the latest turning point, and the two wind spirals are connected by a common tangent. The boundary of the upper latest turning track protection zone is the connection between the turning end point and the tangent line of the outer boundary of the wind spiral, and it is extended outward by 15° and tangent to the protection zone (half width. Figure 5 As shown in the figure, the boundary of the protection zone of the earliest turning track on the lower side is 150 meters to the side of the turn end point and the runway DER, and it extends 15° outward and is tangent to the half width of the protection zone. Figure 6 As shown, it is connected to the position 600 meters inside and 150 meters to the side of the runway entrance, and expands 15° outward to be tangent to the half width of the protected area.

[0050] In some embodiments, the flight track and protection zone drawing model identifies whether the improved ARINC424 terminal area database uses a designated altitude turn departure or a designated point turn departure. If the designated altitude turn departure is used, the distance L from the turning point to the runway DER = the turning point altitude / the departure straight section climb gradient, the turning point altitude is read from the flight procedure data, and the departure straight section climb gradient is read from the operation and graphic key information data. If the designated point turn departure is used, the distance L from the turning point to the runway DER is calculated based on the longitude and latitude of the turning point and the longitude and latitude of the runway DER, the longitude and latitude of the turning point are read from the waypoint data, and the longitude and latitude of the runway DER are read from the runway data.

[0052] S4. Use flight track drawing data and protection zone drawing data to conduct planning and evaluation of airport power facilities, including power transmission lines.

[0053] like Figure 2As shown, a fast drawing system of flight track and protection area based on ARINC424 terminal area includes a database construction system and a flight track and protection area drawing model. The database construction system has an original ARINC424 terminal area database, an operation and graphics key information database and an improved ARINC424 terminal area database. The improved ARINC424 terminal area database is obtained by data fusion processing of the original ARINC424 terminal area database and the operation and graphics key information database. The original ARINC424 terminal area database is obtained by parsing and processing the original text format ARINC424 data. The operation and graphics key information database NAIP data is processed and stored according to the field rules of ARINC424 data. The flight track and protection area drawing model includes a key parameter extraction and calculation module, a flight track drawing module and a protection area drawing module, and the flight track and protection area drawing model has a coordinate system. The key parameter extraction and calculation module is used to identify the flight track termination code of the improved ARINC424 terminal area database and divide the flight track, extract key parameters including runway elevation, distance L from the turning point to the runway, turning point altitude H, indicated airspeed IAS, turning slope α, and turning point positioning tolerance in the flight track, and the key parameter extraction and calculation module calculates the true airspeed TAS, turning rate R, turning radius r, wind impact E θ The flight track drawing module draws the runway and the airport on the coordinate system, draws the runway proximal straight segment track on the coordinate system based on the distance L from the turning point to the runway DER, draws the turning arc on the runway proximal straight segment track on the coordinate system based on the turning radius r, identifies the turning end point of the flight track, draws the straight segment track after the turn based on the turning end point and the tangent of the turning arc, thereby obtaining the track including the turn, and draws other tracks in sequence to obtain the flight track. The protection zone drawing module draws the protection zone on the coordinate system. The flight track and protection zone drawing model is also used to output the flight track drawing data and the protection zone drawing data to the outside.
