[0028] In order to better understand the design scheme of the present application, it is explained below in conjunction with specific application scenarios.

[0029] The airport clearance obstacle assessment method of the embodiment of the present application can be executed by an airport clearance obstacle assessment device, and the airport clearance obstacle assessment device can be implemented by software and / or hardware. The airport clearance obstacle assessment device can be composed of two or more physical entities, or it can be composed of one physical entity. The hardware pointed to by the airport clearance obstacle assessment device essentially refers to computer equipment. For example, the airport clearance obstacle assessment device can be a computer, a mobile phone, a tablet or other smart device.

[0030] In order to better understand the design scheme of the present application, the following first introduces the airport clearance obstacle assessment method of the related art.

[0031] In the current aviation field, the assessment of airport clearance obstacles is generally the responsibility of the designers of the design unit, who search for measurement data, calculate, draw pictures, and finally compile and deliver the documents. Manual data processing has problems such as long cycle, easy errors, and multiple proofreading.

[0032] There are some auxiliary tools available, usually in the form of PC clients, which input various parameters such as the latitude and longitude of obstacles, types, etc. to generate various obstacle restriction surfaces. However, such tools are limited to the reference level, because the data source is single and the static model is used, which cannot be adapted to the actual situation, resulting in large errors and low accuracy in the final evaluation results.

[0033] To this end, an embodiment of the present application proposes an airport clearance obstacle assessment method.

[0034] See also Figure 1 , Figure 1 A flowchart of an airport clearance obstacle assessment method provided in one embodiment of the present application, the method includes the following steps:

[0035] S10: Acquire airport location information, airport environment information, aircraft flight information, and obstacle information.

[0036] The airport location information includes, but is not limited to, the location information of the airport area, the location information of the airport runway area, the length, width and grade of the airport runway, the height of the runway reference point and the longitude and latitude of the runway center point. The airport environment information includes, but is not limited to, the topographic data near or around the airport. The aircraft flight information includes, but is not limited to, the wind speed data, temperature data, and the flight path of the aircraft above or around the airport. The obstacle information includes, but is not limited to, the name of the obstacle, the type of obstacle, the altitude of the obstacle, the longitude and latitude of the obstacle, the magnetic direction and distance of the obstacle relative to the airport, etc.

[0037] In the embodiment of the present application, the airport location information and airport environment information can be obtained from the Aeronautical Information Publication (AIP), and updated airport location information and airport environment information can be obtained from the navigation notice of the civil aviation telegram according to the navigation notice compilation and issuance specifications and navigation notice code selection specifications, obstacle information can be obtained from the obstacle database, and aircraft flight information can be obtained from the ground automatic receiving device. Among them, the ground automatic receiving device receives the aviation flight information sent by the aircraft, and the ground automatic receiving device includes but is not limited to the ADS-B receiving device and some receiving devices based on the ground-to-air data link protocol.

[0038] S20: Obtain a first airport probability model according to the airport location information and aircraft flight information.

[0039] The first airport probability model includes several clearance obstacle limitation surfaces, including conical surface, inner horizontal surface, inner approach surface, approach surface, transition surface, inner transition surface, missed approach surface and take-off climb surface.

[0040] In the embodiment of the present application, the first airport probability model can be directly generated according to the airport location information. In this case, the first airport probability model is a static model. The first airport probability model can also be generated according to the airport location information and the aircraft flight information. In this case, the first airport probability model is a dynamic model.

[0041] S30: Obtain a first terrain model according to the airport environment information and obstacle information.

[0042] The first terrain model is a three-dimensional space model obtained by fitting the obstacle and the terrain within the range where the obstacle is located.

[0043] In the embodiment of the present application, obstacle information input by a user can be received, and the obstacle information can be searched and matched in the obstacle database to determine whether the obstacle information is historical obstacle information. If so, the created terrain model is called. If not, a terrain model is generated according to the obstacle information. A first terrain model is generated according to the terrain model and the airport environment information.

[0044] S40: Matching the first airport probability model and the first terrain model to obtain an airport clearance obstacle assessment result.

[0045] In the embodiment of the present application, whether the obstacle passes the airport clearance assessment is determined by evaluating whether the obstacle limitation surface in the first airport probability model intersects or overlaps with the first terrain model. Specifically, if the first terrain model penetrates the first airport probability model above due to its abrupt shape, it is determined that the obstacle does not pass the airport clearance assessment. If the first terrain model does not penetrate the first airport probability model above, it is determined that the obstacle passes the airport clearance assessment.

[0046] By using the embodiment of the present application, by acquiring airport location information, airport environment information, aircraft flight information and obstacle information;

[0047] According to the airport location information and the aircraft flight information, a first airport probability model is obtained; according to the airport environment information and the obstacle information, a first terrain model is obtained; the first airport probability model and the first terrain model are matched to obtain the airport clearance obstacle assessment result. This application improves the accuracy of the first airport probability model and the first terrain model by introducing the airport environment information and the aircraft flight information, thereby improving the accuracy of the airport clearance obstacle assessment, and does not require manual processing, thereby improving the efficiency of the airport clearance obstacle assessment.

[0048] In an optional embodiment, the aircraft flight information includes wind speed data, temperature data, and a number of flight procedures. Step S20 includes steps S21 to S22, which are specifically as follows:

[0049] S21: Generate an airport probability model based on the airport location information.

[0050] Among them, an airport probability model generation tool can be used to generate a corresponding airport probability model from the airport location information.

[0051] S22: Optimizing the airport probability model according to the wind speed data, the temperature data and a number of flight procedures, the first airport probability model.

[0052] Among them, the flight procedure is a series of maneuvering flights carried out in sequence as specified for aircraft operations, including flight routes, altitudes and maneuvering areas. Specifically, the flight procedure includes several flight paths.

[0053] In the embodiment of the present application, the trajectory of the aircraft is more susceptible to the influence of aerodynamics when the attitude is adjusted. When the aircraft is turning, that is, when the aircraft is making a curved motion, the adjustment of its attitude will introduce additional changes in maneuverability, thereby increasing the instability of the trajectory. In this process, the influence of temperature and wind is more prominent, and the curved path becomes more unreliable than the straight path. Therefore, the influence of wind speed and temperature on each flight path in the flight program is considered, and the airport probability model is optimized according to the flight path to obtain the first airport probability model.

[0054] Based on wind speed data, temperature data and several flight procedures, the accuracy of generating the first airport probability model can be improved.

[0055] In an optional embodiment, step S22 includes steps S221 to S225, which are specifically as follows:

[0056] S221: Traverse each flight path, determine the first angle between the current flight path and the next flight path of the current flight path and the first ratio of the length of the current flight path to the sum of the lengths of all flight paths; based on the first angle and the first ratio, determine the weight ratio of the curved path corresponding to the current flight path, until the weight ratio of the curved path corresponding to each flight path is determined.

[0057] In the embodiment of the present application, the expression of the curve path weight ratio is as follows:

[0058]

[0059] Among them, x represents the weight ratio of the curve path, a represents the first angle, and b represents the first ratio.

[0060] S222: Traverse each flight path, divide the current flight path into an initial segment, a middle segment and a final segment, determine the second angle between the initial segment and the final segment, and the second ratio of the middle segment to the total length of all flight paths; determine the average curve path weight ratio corresponding to the current flight path based on the second angle and the second ratio, until the average curve path weight ratio corresponding to each flight path is determined.

[0061] In the embodiment of the present application, the expression of the average curve path weight ratio is as follows:

[0062] y=B*ln(A / 15) / Π

[0063] Among them, y represents the average curve path weight ratio, A represents the second angle, and B represents the second ratio.

[0064] S223: If the curve path weight ratio is greater than the corresponding average curve path weight ratio, calculate the standard deviation of the average curve path weight ratio.

[0065] In an embodiment of the present application, after obtaining the average curve path weight ratio corresponding to each flight path, the standard deviation calculation formula can be used to calculate the standard deviation corresponding to all flight paths.

[0066] S224: Determine the impact factor of wind speed data and temperature data on each flight path.

[0067] In the embodiment of the present application, wind and temperature will have different effects on the aircraft depending on the flight path, forming three types of events: favorable events, unfavorable events, and no-effect events. Among them, the influencing factors include a first influencing factor, a second influencing factor, and a third influencing factor. The first influencing factor is used to indicate a favorable event, that is, the wind speed and temperature are favorable to the flight path, the second influencing factor is used to indicate an unfavorable event, that is, the wind speed and temperature are not favorable to the flight path, and the third influencing factor is used to indicate a no-effect event, that is, the wind speed and temperature do not affect the flight path.

[0068] S225: Optimize the airport probability model according to the standard deviation and the influencing factor to obtain the first airport probability model.

[0069] In an embodiment of the present application, the standard deviation and the influencing factor determine the model parameters in the airport probability model. According to the standard deviation and the influencing factor, the model parameters in the airport probability model are optimized to obtain a first airport probability model.

[0070] According to wind speed data, temperature data and several flight procedures, the first airport probability model can be automatically and quickly obtained.

[0071] In an optional embodiment, step S225 includes steps S2251 to S2252, which are specifically as follows:

[0072] S2251: If the influencing factor is the first influencing factor, multiply the standard deviation by the preset weight to obtain a first product result; subtract the standard deviation from the product result to obtain a first weight; according to the first weight, iterate the first parameter in the wind speed correction modifier function and the second parameter in the temperature correction modifier function in the airport probability model until the number of iterations meets the first preset number to obtain a first airport probability model; wherein the first influencing factor is used to indicate that the wind speed and temperature are favorable to the flight path.

[0073] In the embodiment of the present application, the expression of the first weight is as follows:

[0074] P1=P(1-K)

[0075] Among them, P1 represents the first weight, P represents the preset weight, and K represents the standard deviation.

[0076] S2252: If the influencing factor is the second influencing factor, multiply the standard deviation by the preset weight to obtain a first product result; add the standard deviation and the product result to obtain a second weight; according to the second weight, iterate the first parameter in the wind speed correction modifier function and the second parameter in the temperature correction modifier function in the airport probability model until the number of iterations meets the first preset number to obtain a first airport probability model; wherein the second influencing factor is used to indicate that the wind speed and temperature are not favorable for the flight path.

[0077] In the embodiment of the present application, the expression of the second weight is as follows:

[0078] P2=P(1+K)

[0079] Wherein, P2 represents the second weight.

[0080] Since the accuracy optimization of the airport probability model depends on the first parameter in the wind speed correction modifier function and the second parameter in the temperature correction modifier function, optimizing the first parameter and the second parameter according to the first weight and the second weight can improve the accuracy of generating the first airport probability model.

[0081] In an optional embodiment, the airport environment information includes GIS data and magnetic variation data, and step S30 includes steps S31 to S32, which are specifically as follows:

[0082] S31: Generate a terrain model based on obstacle information.

[0083] Among them, a terrain model generation tool can be used to generate a corresponding terrain model from obstacle information.

[0084] S32: Optimize the terrain model according to the GIS data and the magnetic variation data to obtain a first terrain model.

[0085] Magnetic variation is the angle between magnetic north and true north. Magnetic variation varies from place to place and changes over time. Changes in magnetic variation can affect navigation accuracy and pose potential risks to flight safety.

[0086] In the embodiment of the present application, the terrain model is optimized through GIS data and magnetic variation data, thereby improving the accuracy of generating the first terrain model.

[0087] In an optional embodiment, step S32 includes step S321, which is specifically as follows:

[0088] S321: According to the GIS data, the third parameter of the GIS modification function in the terrain model is iterated in a loop, and according to the magnetic variation data, the fourth parameter of the magnetic variation modification function in the terrain model is iterated in a loop until the number of iterations meets the second preset number, so as to obtain the first terrain model.

[0089] In an embodiment of the present application, since the accuracy optimization of the terrain model depends on the third parameter of the GIS modification function and the fourth parameter of the magnetic variation modification function, the accuracy of generating the first terrain model can be improved by optimizing the third parameter and the fourth parameter according to the GIS data and the magnetic variation data.

[0090] In an optional embodiment, step S40 includes steps S41 to S42, which are specifically as follows:

[0091] S41: Obtaining clearance curve coordinates according to the first airport probability model; and obtaining terrain curve coordinates according to the first terrain model.

[0092] Among them, the clearance curve coordinates refer to the coordinates of points on each obstacle limitation surface. The terrain curve coordinates refer to the coordinates of points on the obstacle.

[0093] S42: Determine whether there is interference between the terrain curve coordinates and the clearance curve coordinates; if there is interference, determine that the obstacle has not passed the airport clearance assessment; if there is no interference, determine that the obstacle has passed the airport clearance assessment.

[0094] In the embodiment of the present application, the distance between the terrain curve coordinates and the clearance curve coordinates can be calculated. If the distance is greater than or equal to a preset threshold, it is determined that the terrain curve coordinates and the clearance curve coordinates interfere with each other, and the obstacle fails the airport clearance assessment. If the distance is less than the preset threshold, it is determined that the terrain curve coordinates and the clearance curve coordinates do not interfere with each other, and the obstacle passes the airport clearance assessment.

[0095] By comparing the coordinates of the terrain curve with the coordinates of the clearance curve, the airport clearance obstacle assessment results can be obtained automatically and quickly.
