Description

Technical Field

[0001] The present invention relates to the field of aviation, and in particular to a high-voltage line lighting method based on ADS-B flight data. Background Art

[0002] In recent years, airport clearance safety has been paid more and more attention, which is related to the healthy development of civil aviation, the flight safety of aircraft and the safety of life and property of the people, and the responsibility is heavy. However, most airports in my country are not located in plains, and the surrounding terrain is mostly complex. With the construction of infrastructure, the number of artificial obstacles around airports is increasing, which may threaten aviation safety.

[0003] In order to ensure aviation safety, some obstacles around the airport should be managed and the visibility of obstacles around the airport should be improved. Obstacles are often marked by installing obstacle visual aids to improve the airport's safe operation level.

[0004] With the development of economy and the improvement of productivity, the demand for electricity in industry and life is also increasing, and the construction of high-voltage line projects is also increasing day by day. A high-voltage line often transmits electricity between two or more substations. It spans a long distance and the high-voltage transmission line tower is high. It is a common artificial obstacle outside the airport. For high-voltage lines within the airport clearance protection range, it may have a certain impact on the safe operation of the airport. It is necessary to install obstacle visual aids to let production personnel know the existence of obstacles and achieve a warning effect. The common way is to install obstacle lights and set obstacle signs.

[0005] According to existing regulations and specifications, the installation specifications for high-voltage power line tower obstacle lights are mostly based on airport obstacle limitation surfaces and comprehensive considerations of navigation research opinions. Among them, the airport obstacle limitation surface is to ensure the safety of aircraft takeoff and landing and the safe operation of the airport, and to prevent the airport from being unusable due to the increase of obstacles around the airport. Several types of obstacle limitation surfaces are specified to limit the height of obstacles in the airport and its surrounding areas, such as Figure 1 shown.

[0006] The existing technology determines the lighting plan based on the position of the obstacle relative to the airport and the clearance breakthrough situation. If the obstacle breaks through the airport obstacle restriction surface, or is in the key area near takeoff and landing, and there are no existing tall obstacles or other warning signs, then it needs to be lit; the lighting plan for other obstacles within the airport clearance range needs to be determined through navigation research.

[0007] The existing high-voltage line lighting scheme is partially determined based on navigation research, but the scope and standards of navigation research are not clear, and there is no clear operability; if it is only considered from the perspective of navigation assessment, the perspective of considering this issue is also from the design perspective. In actual operation, flights do not strictly refer to standard flight routes. Due to the influence of external factors (air pressure, temperature, wind speed), the altitudes of different flight stages are not completely consistent with the aeronautical chart. Analyzing the obstacle lighting scheme from the perspective of navigation assessment alone may not be able to fully analyze the actual flight field scenario. Therefore, it is urgent to propose a method that can more accurately install obstacle lights on tower obstacles according to the actual flight route of the flight. Summary of the invention

[0008] The purpose of the present invention is to provide a high-voltage line lighting method based on ADS-B flight data, using a geographic information system to analyze the ADS-B historical flight tracks. The analysis of the horizontal range of the historical flight tracks can be used to determine high-voltage line lighting schemes and lighting rules.

[0009] In order to achieve the above object, the technical solution adopted by the present invention is: a high-voltage line lighting method based on ADS-B flight data, the method steps are as follows:

[0010] Step 1: Analyze the historical data of the aircraft and the high-voltage line height transmitted by ADS-B to obtain the historical track and high-voltage line height of the aircraft;

[0011] Step 2: Calculate the "horizontal track area" based on the horizontal range of the historical track, and determine the horizontal range of the high-voltage line lights through the "horizontal track area";

[0012] Step 3. For obstacles within the "horizontal track area", analyze the historical track heights within the "horizontal track area" and set the basic height. If the height of the high-voltage line tower exceeds the basic height, lights need to be installed. If it does not exceed the basic height, lights do not need to be installed.

[0013] Preferably, in step 2, the horizontal track area calculation method is:

[0014] First, the track data is processed using geographic information system;

[0015] Then, the aircraft tracks with relatively close horizontal ranges are statistically divided, and the track group composed of relatively close tracks is formed, with the outermost edge track of the track group as the basic boundary;

[0016] Finally, the sum of the width between the basic boundary tracks on both sides, the horizontal positioning error of the position receiving equipment, and 1 / 2 the wingspan of the aircraft is the "horizontal track area".

[0017] Preferably, the method for processing the track data is to statistically organize the waypoints, route information and track information (longitude, latitude, altitude, aircraft type, time, flight number, etc.) of the track data, enter the location information and attributes of the track using a geographic information system, and draw the point information recorded by ADS-B into the aircraft's operating trajectory.

[0018] Preferably, the basic boundary is determined by combining waypoint and route information analysis to statistically divide multiple aircraft tracks that continuously fly over the same waypoint and have relatively close horizontal ranges. These tracks are formed by aircraft operating along the same route. The track group composed of such tracks is smoothed with one or more outermost edge tracks of the track group, which is the basic boundary.

[0019] Preferably, in step 3, the lowest altitude of the aircraft's flight track in the direction of travel is used as the lowest flight altitude along the direction of travel within the "horizontal track area", and the basic altitude is set based on the lowest flight altitude combined with geographical environmental factors.

[0020] Preferably, the height of common high-voltage line towers is generally less than 150m. The obstacle clearance margin is 300m for conventional airports and 600m for mountain airports. Therefore, the minimum height of the flight track around the high-voltage line is 450m for conventional airports and 750m for mountain airports, which is the base height.

[0021] Compared with the prior art, the advantages of the present invention are: starting from the flight track, the present invention proposes to use the flight history trajectory data recorded by ADS-B to determine the actual aircraft flight area, and a lighting scheme for high-voltage line towers located under the flight track and with a small difference from the true height of the aircraft. It supplements a navigation assessment method, enhances the operability of obstacle lighting schemes that are not clearly defined in regulations, and is more conducive to pilots visually observing the existence of higher obstacles near the track. Moreover, this scheme is based on the actual operation of the flight and is more targeted and accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below. A method for installing lights on a high voltage line based on ADS-B flight data is as follows. Figure 2 and Figure 3 ,

[0026] Step 1: Analyze the historical data of aircraft and high-voltage line height transmitted by ADS-B to obtain the historical track and high-voltage line height of the aircraft; ADS-B can automatically obtain parameters from relevant airborne equipment and broadcast the aircraft's position, altitude, speed, heading, identification number and other information to other aircraft or ground stations for controllers to monitor the aircraft status. To improve the accuracy of the data, the historical data of aircraft transmitted by ADS-B is used for analysis based on three years of historical data.

[0027] The reason why the present invention adopts ADS-B is that the method of obtaining historical tracks using data from aircraft monitoring equipment is relatively direct; and as aircraft monitoring equipment, ADS-B ground receiving equipment has lower costs and is easier to install than primary radar and secondary radar; and most airports currently have ADS-B deployed, which can achieve coverage of a larger area and record more complete aircraft tracks around most airports, increasing the traceability of historical tracks.

[0028] Step 2: Calculate the "horizontal track area" based on the horizontal range of the historical track, and determine the horizontal range of the high-voltage line lights through the "horizontal track area";

[0029] To perform horizontal track area calculations:

[0030] First, the waypoints, route information and track information (longitude, latitude, altitude, aircraft type, time, flight number, etc.) are statistically collated, and the location information and attributes of the track are entered using the geographic information system, and the point information recorded by ADS-B is plotted into the aircraft's operating trajectory;

[0031] Then, combined with the waypoint and route information analysis, the aircraft tracks that continuously fly over the same waypoint and have a relatively close horizontal range are statistically divided. These tracks are operated by aircraft along the same route. The track group composed of such tracks is smoothed with one or more edge tracks on the outermost side of the track group as the basic boundary. This basic boundary can determine the operating range of the historical flight track and provide a reference for the lighting range, which is very accurate and appropriate for actual operation.

[0032] Finally, the width between the basic boundary tracks on both sides, the horizontal positioning error of the position receiving device, and the sum of 1 / 2 of the aircraft wingspan length are used as the "horizontal track area". The lighting analysis of the tower obstacle can be carried out through this "horizontal track area". Among them, since the GNSS position receiving device of ADS-B has a certain horizontal positioning error, and the aircraft wingspan has a certain width, the width between the basic boundary tracks on both sides, the horizontal positioning error of the position receiving device, and the sum of 1 / 2 of the aircraft wingspan length are used as the "horizontal track area". This horizontal track area is the only way for the aircraft in this airspace.

[0033] The horizontal track area calculated by the present invention can determine the current and past operating range of the aircraft. Based on the range of this horizontal track area, the positional relationship between the aircraft and the ground objects can be clarified, and this positional relationship more accurately reflects the relative positional relationship between the track and the ground objects.

[0034] Step 3. For obstacles within the "horizontal track area", analyze them in combination with the historical track altitude of the aircraft in the "horizontal track area". Use the lowest altitude of the aircraft's flight track in the direction of operation as the lowest flight altitude along the direction of operation in the "horizontal track area". Set the basic altitude based on the lowest flight altitude combined with geographical environmental factors. If the height of the high-voltage line tower exceeds the basic height, lights need to be installed. If it does not exceed the basic height, lights do not need to be installed.

[0035] The method of setting the basic height by combining the minimum flight altitude with geographical factors is that the common high-voltage line tower height is generally below 150m, and the obstacle clearance margin is 300m for conventional airports and 600m for mountain airports. Therefore, the height obtained by the difference between the lowest height of the track around the high-voltage line and 450m for conventional airports (750m for mountain airports) is the basic height. By truly calculating the track of the high-voltage line tower and the aircraft, the accuracy of the present invention in the actual operation process is ensured. For the tower obstacles within the airport obstacle restriction surface, the installation scheme under the existing technology is maintained to ensure that the towers near the airport area can be clearly found, thereby ensuring navigation safety.

[0036] In summary, the present invention takes the flight track as the starting point, proposes to use the flight history trajectory data recorded by ADS-B to determine the actual aircraft flight area, and provides a lighting scheme for high-voltage line towers located under the flight track and with a small difference from the true height of the aircraft. It supplements a navigation assessment method, enhances the operability of obstacle lighting schemes that are not clearly defined in regulations, and is more conducive to pilots visually observing the existence of higher obstacles near the track. Moreover, this scheme is based on the actual operation of the flight and is more targeted and accurate.

[0037] In addition, the horizontal track area of ​​the present invention can also be used as a basis to further provide some references for other research directions, such as special research on noise, electromagnetic interference of high-voltage lines on ground stations on the aircraft's operating trajectory, etc.
