Description

Technical Field

[0001] This application belongs to the field of flight simulation, and particularly relates to a method, device, and equipment for calibrating instrument landing station data of an aviation simulator. Background Art

[0002] The Instrument Landing System (ILS), also known as the blind landing system, is one of the most important radio navigation systems on board an aircraft and is also the most widely used precision approach and landing guidance system for aircraft. The aviation simulator simulates according to the functions and performances of the on-board equipment of a real aircraft. Simulating the instrument landing system is one of the key contents of the simulation development of the aviation simulator. According to the working principle of the instrument landing system of a real aircraft, by receiving and responding to the radio signals of the ground instrument landing system navigation station, the function of the radio navigation system can be realized. The realization of the simulation function of the instrument landing system model of the aviation simulator also relies on the data information of the ground instrument landing station to complete the calculation of key navigation parameters such as the localizer and glide slope deviation.

[0003] Currently, when calibrating the instrument landing station data, the method of manual operation and recording of coordinate points is used to complete the calibration of the instrument landing station. It is necessary to reposition the position of the simulator aircraft to the position of the feature point. During the simulation process of the aviation simulator, the position parameter information of the above-mentioned feature point needs to be calibrated by the simulator visual system for the actual positions of the airport and the runway before it can be determined. Therefore, if the position of the above-mentioned feature point is not calibrated or has not been determined, it will lead to the inability to carry out the above-mentioned manual calibration method or there will be a large deviation in the calibration result, and it is necessary to re-complete the calibration work according to the updated position point data related to the airport and the runway, which will cause the repetition of the station calibration work and greatly affect the simulation development efficiency.

Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0028] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0029] Currently, when calibrating the instrument landing station data, the method of manually operating and recording the coordinate points to complete the calibration of the instrument landing station is adopted, which not only has low calibration efficiency but also low accuracy.

[0030] Please refer to Figure 1 , the instrument landing station data calibration system 100 includes a human-computer interaction module, a database interaction module, and a core algorithm module. The human-computer interaction module, the database interaction module, and the core algorithm module are respectively communicatively connected. The human-computer interaction module is used for database login and implementing human-computer interaction logic. The human-computer interaction module also includes a main function display window. Based on the database login, it connects to the database of the database interaction module to realize the communication between the human-computer interaction module and the database. The database interaction module is used to obtain database parameters and calibration data, as well as update data. Then, based on the updated data, it performs data format conversion, and the converted station calibration parameters are displayed through the main function display window of the human-computer interaction module. The station calibration control instruction is output through the human-computer interaction logic of the human-computer interaction module. Then, the core algorithm module obtains the station calibration input parameters from the database interaction module. Based on the Localizer (LOC) station calibration algorithm and the Glide Slope (GS) station calibration algorithm, it generates station calibration parameters and sends the generated station calibration parameters to the database interaction module for data update. The LOC station calibration algorithm and the GS station calibration algorithm are respectively generated through a spatial resolution algorithm.

[0031] Please refer to Figure 2 , the instrument landing station data calibration method for an aviation simulator includes the following steps.

[0032] S201, obtain a calibration instruction.

[0033] Among them, the calibration instruction includes target airport indication information for indicating a target airport and a target runway number. The target airport indication information can be the four-letter code of the airport. Each airport includes multiple runways, and each runway corresponds to a runway number.

[0034] S202, obtain runway data and instrument landing station data according to the target airport indication information and the target runway number.

[0035] Among them, the runway data is used to indicate the target runway, and the instrument landing station data is used to indicate the target instrument landing station corresponding to the target runway. In a specific implementation, the runway data includes information such as the latitude of the takeoff point, the longitude of the takeoff point, the altitude of the takeoff point, the true course of the takeoff point, and the runway length. The instrument landing station data includes the longitude of the LOC station, the latitude of the LOC station, the altitude of the LOC station, the heading of the LOC station. The longitude of the GS station, the latitude of the GS station, and the altitude of the GS station. The instrument landing station data obtained at this time can be the instrument landing station data before calibration.

[0036] S203, determine the calibration data of the target instrument landing station according to the runway data and the instrument landing station data.

[0037] Among them, the verification data includes the position verification data of the LOC station, the course verification data of the LOC station, the position verification data of the GS station, etc.

[0038] S204, update the instrument landing station data according to the verification data.

[0039] Among them, after the core algorithm module verifies the station data, the database interaction module performs format conversion on the verified data to store the converted data in the database. To update the station data in the database. Then the database interaction module needs to convert the corrected instrument landing system station data information obtained by the core algorithm module into a specific string format displayed by the database software and display it through the human-computer interaction module. The data conversion rules can be shown in Table 1.

[0040] Table 1

[0041] When updating the station data in the database, the four-letter airport code and runway number can be mapped to the four-letter airport code and runway number in the IlsDatabase form of the database, and the software encodes the SQL handle. According to the index of the station information type, the calibrated data information is updated to the IlsDatabase form of the database.

[0042] It can be seen that in this embodiment, first, a correction instruction is obtained. The correction instruction includes target airport indication information for indicating a target airport and a target runway number. Then, runway data and instrument landing station data are obtained according to the target airport indication information and the target runway number. The runway data is used to indicate the target runway, and the instrument landing station data is used to indicate the target instrument landing station corresponding to the target runway. Then, the verification data of the target instrument landing station is determined according to the runway data and the instrument landing station data. Finally, the instrument landing station data is updated according to the verification data. It can realize automatic verification and update of the instrument landing station data, improve the data verification efficiency and verification accuracy.

[0043] In a possible embodiment, the target instrument landing station includes a LOC station, and the calibration data includes a first target position of the LOC station. Determining the calibration data of the target instrument landing station according to the runway data and the instrument landing station data includes: determining a first longitude parameter, a first latitude parameter, a runway heading, and a runway length of a takeoff point of the target runway according to the runway data; determining a translation distance according to the runway length and a preset distance; determining a moving direction according to the runway heading; and determining a second longitude parameter and a second latitude parameter of the LOC station according to the first longitude parameter, the first latitude parameter, the translation distance, and the moving direction, where the second longitude parameter and the second latitude parameter are used to indicate the first target position.

[0044] Among them, the sum of the runway length and the preset distance can be used as the translation distance. Then, based on the longitude and latitude parameters of the takeoff point of the airport runway, calculate the translation of the takeoff point along the runway heading based on the translation distance, and substitute it into the CalcPosition function for calculation to obtain the longitude and latitude coordinates of the corrected LOC station position.

[0045] In specific implementation, the CalcPosition function is a kind of spatial solution algorithm. Its principle is based on the WGS84 ellipsoid model, considering the differential geometric relationship on the ellipsoid and considering the earth curvature and direction change, and converting the displacement amount in the plane rectangular coordinate system into the longitude and latitude change amount in the geodetic coordinate system through the radius of curvature. The algorithm function is defined as follows: def CalcPosition(Latitude, Longitude, Heading, Distance) The input parameters of the function are respectively: starting point latitude, starting point longitude, moving direction, and moving distance.

[0046] The output parameters of the function are respectively: translated latitude, translated longitude.

[0047] It can be seen that in this embodiment, automatically correcting the position of the LOC station based on the longitude and latitude of the takeoff point, the runway heading, and the runway length can improve the efficiency and accuracy of data correction.

[0048] In a possible embodiment, the calibration data includes a target heading of the LOC station. Determining the calibration data of the target instrument landing station according to the runway data and the instrument landing station data includes: determining a direction from the takeoff point to the LOC station according to the first longitude parameter, the first latitude parameter, the second longitude parameter, and the second latitude parameter; and determining the direction from the takeoff point to the LOC station as the target heading.

[0049] Among them, when calibrating the heading of the LOC station, after obtaining the corrected longitude and latitude of the LOC station, the azimuth between the two points is calculated by substituting into the CalcBearing function according to the longitude and latitude parameters of the take-off point of the airport runway, which is the heading of the corrected LOC station. Thus, the calibration of the longitude, latitude position and heading of the LOC station is completed.

[0050] In specific implementation, the CalcBearing function is a kind of spatial resolution algorithm. Its principle is to consider the shape of the earth ellipsoid (WGS84 parameters) and use the reduced latitude to eliminate the influence of the flattening. First, the reduced latitude is calculated to convert the geodetic latitude into the reduced latitude and eliminate the influence of the ellipsoid flattening. Second, the longitude difference between the two points is calculated. Furthermore, the azimuth angle between the two points is calculated based on the spherical triangle formula. The algorithm function is defined as follows: def CalcBearing(Latitude1, Longitude1, Latitude2, Longitude2) The input parameters of the function are respectively: the latitude of the first point, the longitude of the first point, the latitude of the second point, and the longitude of the second point.

[0051] The output parameter of the function is: the azimuth from the first point to the second point, in degrees.

[0052] It can be seen that in this embodiment, the heading of the LOC station is automatically calibrated based on the longitude and latitude of the take-off point and the longitude and latitude of the corrected LOC station, which can improve the efficiency and accuracy of data calibration.

[0053] In a possible embodiment, the target instrument landing station includes a GS station, and the verification data includes the second target position of the GS station. Determining the verification data of the target instrument landing station according to the runway data and the instrument landing station data includes: obtaining the initial height of the target runway according to the runway data; obtaining the target height of the GS station according to the instrument landing station data; determining the glide path height difference according to the target height, the initial height and a preset height difference; determining the horizontal distance between the ground projection of the initial approach point of the aircraft and the GS station according to the glide path height difference and a preset angle; moving a preset distance along the runway heading in the first direction from the take-off point to reach the repositioning point; moving the horizontal distance along the runway heading in the second direction from the repositioning point to reach the target point, and the position of the target point is the second target position of the GS station.

[0054] Wherein, the first moving direction and the second moving direction are opposite directions. In particular, the first moving direction is the direction away from the GS station. When calibrating the position of the GS station, a preset height difference can be determined first. This preset height difference is related to the aircraft descent rule. For example, it is stipulated that the aircraft approaches and lands along the flight principle of the A-degree glide angle, and the position of the B-nautical mile approach point is on the preset glide line. Then, in combination with the B-nautical mile horizontal distance, the preset height difference DeltaH of the B-nautical mile repositioning point relative to the takeoff point of the airport runway can be calculated. The specific implementation of converting the height difference to the metric unit is as follows: DeltaH = B 1852 / tan(A π / 180.0) In particular, the preset angle in this solution can refer to A degrees. A degrees can refer to 3 degrees. B nautical miles can refer to 3 nautical miles or 6 nautical miles, etc.

[0055] When obtaining the preset height, the actual height at the B-nautical mile position can be calculated based on the initial height of the airport runway takeoff point. Then, by subtracting the GS station height of the corresponding airport runway obtained from the database from the actual height, the glide height difference GsDeltaH can be obtained. Then, based on the flight principle of the A-degree glide angle in the above descent rule, the horizontal distance GsDeltaDistance between the coordinate point of the ground projection of the B-nautical mile position (i.e., the initial approach point of the aircraft) and the GS station coordinate point can be calculated inversely as follows: GsDeltaDistance = GsDeltaH / tan(A π / 180.0) Then, according to the longitude and latitude position of the airport runway takeoff point, along the runway heading, translate backward by B nautical miles, and substitute it into the above CalcPosition function to obtain the longitude and latitude of the B-nautical mile ground projection coordinates, that is, obtain the longitude and latitude of the repositioning point. Then, based on the repositioning, translate forward by the distance of GsDeltaDistance along the runway heading to obtain the longitude and latitude parameters of the target point, thereby completing the calibration of the longitude and latitude position of the GS station. When determining the longitude and latitude parameters of the target point, the horizontal distance can be used as the translation distance, and the runway heading is the moving direction. Based on the longitude parameter and latitude parameter of the repositioning point, substitute them into the above CalcPosition function for calculation.

[0056] It can be seen that in this embodiment, based on the aircraft descent regulations and the height of the GS station, etc., the position of the GS station is automatically corrected, which can improve the efficiency and accuracy of data correction.

[0057] In a possible embodiment, the obtaining of the calibration instruction includes: displaying a calibration object sub-interface on an instrument landing station data calibration interface, where airport indication information and a runway number corresponding to each airport indication information are displayed on the calibration object sub-interface; receiving a calibration request for the target airport indication information and the target runway number, and obtaining the calibration instruction.

[0058] Among them, please refer to Figure 3 , multiple airport indication information is displayed in the calibration object sub-interface 301, such as airport four-character codes including "ZSPD", "ZSSS", and "ZBAA", etc. At the same time, the runway numbers of the runways corresponding to each airport are also displayed in the calibration object sub-interface 301. For example, the runway numbers included in the airport corresponding to "ZSSS" are "36L", "18L", "36R", and "18R", and the runway numbers included in the airport corresponding to "ZBAA" are "36L", "18L", and "36R". The user can select the target runway number of the target airport that needs to be calibrated in the calibration object sub-interface 301 to achieve the calibration of a specific one or more runways. At the same time, if the user does not select a specific runway number, the user can also click the "All Calibration" control in the calibration object sub-interface 301 to achieve the calibration of the instrument landing station data corresponding to all runways.

[0059] It can be seen that in this embodiment, the airport information and runway information are displayed on the display interface, enabling the user to independently select or select all the runways to be calibrated based on the display interface, improving the calibration convenience and the user experience.

[0060] In a possible embodiment, a data update result sub-interface is displayed on the instrument landing station data calibration interface, and database update status information is displayed on the data update result sub-interface. The database update status information is used to indicate the airport indication information and runway number corresponding to the successfully updated instrument landing station data; after updating the instrument landing station data according to the verification data, the method further includes: receiving a request to view the update result for the target indication information and the target runway number; and displaying the updated instrument landing station data of the target instrument landing station on the data update result sub-interface.

[0061] Among them, please refer to Figure 3, in the data update result sub-interface 302, the airport information and runway information that have been data-corrected can be displayed in real time. For example, it is displayed that at 20xx-xx-xx 18:19:06, the database update result is: "ZSPD 35R data update successful!", "ZSSS 36L data update successful!", and "ZSSS 18R data update successful!" etc. After the database interaction module converts the format of the correction data from the core algorithm module, it updates the database and then feeds back the update result to the human-computer interaction module. At this time, the human-computer interaction module can display the update situation in the data update result sub-interface 302.

[0062] In specific implementation, please refer to Figure 4 , the user can also select a specific runway number in the calibration object sub-interface 301 to view the correction result of that runway number. In particular, before displaying the correction result, the database interaction module will convert the format of the updated data and then send the data after format conversion to the human-computer interaction module for display.

[0063] For example, if the user selects to view the ILS data of "18R" included in the target airport "ZBAA", at this time, "ZBAA 18R ILS data" is displayed in the data update result sub-interface 302, including the corrected LOC dimension (40.053773), the corrected LOC longitude (116.577245), the corrected LOC heading 173.175, the corrected GS latitude (40.102058), the corrected GS latitude (116.569719), and the GS altitude (38.404799).

[0064] It can be seen that in this embodiment, the update situation and update result of the instrument landing system station data of each runway can be viewed on the display interface, improving the user experience and the convenience of information query.

[0065] In a possible embodiment, before obtaining the runway data and the instrument landing system station data according to the target airport indication information and the target runway number, the method further includes: displaying a database connection login interface on the instrument landing system station data calibration interface; obtaining database information based on the database connection login interface, where the database information is used to indicate a target database, and the target database includes the runway data and the instrument landing system station data of multiple airports; establishing a communication connection with the target database according to the database information; and obtaining the runway data and the instrument landing system station data according to the target airport indication information and the target runway number includes: obtaining the runway data and the instrument landing system station data from the target database according to the target airport indication information and the target runway number.

[0066] Among them, the database connection login interface is asFigure 5 As shown, the user can enter the IP address (127.0.0.1) of the database to be associated, the port number of the database (5432), the software name of the database (postgres), the name of the database to be connected (xxxx), and the login password (123456) on this interface. Then the user clicks the connection control to associate the target database and establish communication with the database software. After successful association, as Figure 6 shown, a connection success prompt message ("Successfully connected to the Postgresxxxx database!") will be displayed on the database connection login interface.

[0067] In the specific implementation, when obtaining data, the data information in the specific data form in the target database can be obtained through the SQL handle, and the data information required for the instrument landing station calibration can be further identified and filtered according to the preset algorithm rules. The database interaction form and data information are shown in Table 2 below.

[0068] Table 2

[0069] The solution for obtaining data based on the preset algorithm is as follows: First, data interaction is performed with the Airports form in the target database through the software-coded SQL handle. Given the requirements of the departure airport and the landing airport, the four-letter codes of the corresponding airports in the form are obtained, and an airport code list is established for data storage. The data structure and example of the airport code list are as follows: Data structure: AirportID = [airport code 1, airport code 2, airport code 3,...] Data example: AirportID = [ZBAA, ZBSD, ZSSS,...] Based on the obtained four-letter codes of the required airports, a data mapping with the Runway database is encoded. First, traverse according to the airport code list (AirportID), traverse to obtain all the runway numbers included in each corresponding airport code in the Runway database, and then obtain information such as the takeoff point latitude, takeoff point longitude, takeoff point altitude, takeoff point true course, takeoff point true course, and runway length corresponding to each runway number, and store it in the Map data structure. The example of the Map data structure is shown below: Data structure: AirportRunwayMap = { airport code 1 : [runway number, [takeoff point latitude, takeoff point longitude, takeoff point altitude, takeoff point true course, runway length] ], airport code 2 : [runway number, [takeoff point latitude, takeoff point longitude, takeoff point altitude, takeoff point true course, runway length] ], …… Airport code N: [Runway number, [Takeoff point latitude, Takeoff point longitude, Takeoff point altitude, True course of takeoff point, Runway length]] } Data example: AirportRunwayMap = { ZSPD: ["35L", ["N31:07:32.0664", "E121:47:39.426", 17, 342.115, 11154]], ZSPD: ["17R", ["N31:09:17.2584", "E121:46:59.862", 13, 162.115, 11154]], ……} According to the Map data structure corresponding to the airport code and airport runway information obtained, the software codes traverse the runway numbers corresponding to all required airports stored in the Map, and establish indexes with the LOC and GS station information in the IlsDatabase form to obtain the LOC station longitude, LOC station latitude, LOC station altitude, GS station longitude, GS station latitude, and GS station altitude data of all runways included in the required airports.
