Description

Technical Field

[0001] The present invention relates to the field of aerospace technology, and in particular to a flight corridor planning method for protecting aircraft flight safety based on GPS. Background Art

[0002] The flight corridor simulates a 3D corridor image on the map by setting a series of parameters, and conducts real-time analysis of the flight trajectories of a single flight or even multiple flights within a specific time period to verify whether they strictly follow the established flight routes. This function not only ensures the safety and accuracy of the flight, but also greatly improves the efficiency of flight management.

[0003] During the take-off and landing of an aircraft, a flight corridor needs to be set up to control the flight track of the aircraft. However, the existing flight corridor is mainly based on the tower observing radar data, and then the tower notifies the pilot to adjust the aircraft track. This method has the following disadvantages:

[0004] 1. There may be delays in this process, especially in busy airspace, where communication frequencies may be congested, resulting in delayed information delivery;

[0005] 2. Radio communications may result in unclear or misunderstood information, especially in high noise environments or when communication quality is poor, increasing the risk of pilots executing incorrect instructions;

[0006] 3. The lack of automated and intelligent trajectory optimization methods may result in a less-than-ideal flight path and reduce flight efficiency.

[0007] So how to reduce the risk of mid-air collisions during aircraft takeoff and landing, avoid air traffic chaos, reduce the impact of aviation noise, and improve flight efficiency has become an urgent problem that needs to be solved in contemporary flight control.

[0008] Based on this, the present invention designs a flight corridor planning method based on GPS to protect aircraft flight safety, so as to solve the above-mentioned problems of how to reduce the risk of aircraft mid-air collision, avoid air traffic chaos, reduce the impact of aviation noise, and improve flight efficiency. Summary of the invention

[0009] The purpose of the present invention is to provide a flight corridor planning method based on GPS to protect aircraft flight safety, so as to solve the problem of how to reduce the risk of aircraft mid-air collision, avoid air traffic chaos, reduce the impact of aviation noise, and improve flight efficiency in the above-mentioned background technology.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a flight corridor planning method for protecting aircraft flight safety based on GPS, based on a remote planning service center, accepting aircraft service applications, establishing a three-dimensional space mission model according to the service application, and determining the air flight corridor based on the three-dimensional space mission model by using the global positioning system (GPS) in combination with past historical flight data and according to the current geographical location of the airport and surrounding environmental factors, namely:

[0011] S1. Use the global positioning system (GPS) to obtain ground longitude and latitude points;

[0012] S2. Determine a point at the bottom of the flight corridor according to the ground latitude and longitude points and the height of the flight corridor from the ground;

[0013] S3. Determine the second point at the bottom of the flight corridor based on the point in the air plus the width of the flight corridor;

[0014] S4. Determine the positions of two points at the top of the flight corridor according to the two points at the bottom of the flight corridor and the height of the flight corridor;

[0015] S5. Finally, the area of ​​the flight corridor is finally confirmed based on the length of the flight corridor.

[0016] Preferably, the historical flight data includes current and past route usage, which is used to evaluate the air traffic density in each area, especially the traffic density during peak hours.

[0017] Preferably, after evaluating the air traffic density of each area, data analysis tools are used to predict the future number of flights and flight paths to ensure that the flight corridor can adapt to future needs and preliminarily determine the set area of ​​the flight corridor and the height and width of the corridor.

[0018] Preferably, the surrounding environment includes ground terrain and obstacles (such as mountains, tall buildings, etc.), analyzes the impact on the aircraft's flight path, and determines which areas need to be avoided or require special height restrictions. In order to ensure the safety of the flight, the height, width and length of the flight corridor from the ground are further determined.

[0019] Preferably, in the process of determining the flight corridor, the impact of aircraft noise on the surrounding environment should also be taken into account. A noise propagation model should be used to evaluate the noise impact of aircraft passing through different areas. Professional equipment should be used to measure and collect noise data generated by aircraft passing through aerial flight corridors at different altitudes above the ground in villages or densely populated areas. The relationship between noise data and the altitude of the flight corridor above the ground should be analyzed to find an optimal altitude above the ground. The height, width and length of the flight corridor from the ground should be finally determined in combination with the geographical location of the airport and surrounding environmental factors.

[0020] Preferably, the height, width and length of the flight corridor from the ground should be determined based on terrain data and 3D maps.

[0021] An air traffic control system comprises a receiving unit and a transmission unit, wherein the receiving unit is used to receive synchronous data of the longitude and latitude, height from the ground, own height, width and length of a flight corridor, and the transmission unit is used to transmit the synchronous data to the aircraft, so that the pilot can quickly understand the information of the current flight corridor and judge whether his own track is within the corridor.

[0022] A flight corridor software comprises a processing unit and a transmission unit, wherein the transmission unit is used to transmit synchronous data of the longitude and latitude, height from the ground, own height, width and length of the flight corridor to an air traffic control system, and the processing unit is used to execute modification instructions on the longitude and latitude, height from the ground, own height, width and length of the air corridor.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention can not only enable different aircraft to fly at different altitudes and routes in the air by specifying clear flight paths and altitude layers through air flight corridors, thereby avoiding conflicts between aircraft, reducing the risk of mid-air collisions of aircraft and the impact of aircraft noise on the surrounding environment, but also enable aircraft to organize and allocate air traffic flow more quickly even if they are on busy routes, ensuring that aircraft fly in an orderly manner along prescribed routes and avoiding congestion and chaos in the airspace.

[0025] 2. The present invention connects aircraft with towers through aerial flight corridors, providing a clear reference framework for pilots and towers. It can not only simplify communication and coordination, reduce the complexity of instructions and the possibility of misunderstanding, and improve management efficiency, but also provide aircraft with the most fuel-efficient routes, allowing aircraft to fly at more ideal altitudes and paths, saving fuel, shortening flight time, and improving flight efficiency.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1-2 As shown, a flight corridor planning method for protecting aircraft flight safety based on GPS includes accepting service applications from aircraft based on a remote planning service center, establishing a three-dimensional space mission model based on the service application, and determining the air flight corridor based on the three-dimensional space mission model by combining the global positioning system (GPS) with past historical flight data and according to the current geographical location of the airport and surrounding environmental factors, namely:

[0036] S1. Use the global positioning system (GPS) to obtain ground longitude and latitude points;

[0037] S2. Determine a point at the bottom of the flight corridor according to the ground latitude and longitude points and the height of the flight corridor from the ground;

[0038] S3. Determine the second point at the bottom of the flight corridor based on the point in the air plus the width of the flight corridor;

[0039] S4. Determine the positions of two points at the top of the flight corridor according to the two points at the bottom of the flight corridor and the height of the flight corridor;

[0040] S5. Finally, the area of ​​the flight corridor is finally confirmed based on the length of the flight corridor.

[0041] Among them, historical flight data includes current and past route usage, which is used to evaluate the air traffic density in each area, especially the traffic density during peak hours. After evaluating the air traffic density in each area, data analysis tools are used to predict the future number of flights and flight paths to ensure that the flight corridor can adapt to future needs, preliminarily determine the setting area of ​​the flight corridor and the height and width of the corridor. The surrounding environment includes ground terrain and obstacles (such as mountains, tall buildings, etc.), analyze the impact on the aircraft's flight path, and determine which areas need to be avoided or require special height restrictions. In order to ensure the safety of flight, the flight corridor is further determined to be at a certain height from the ground. The height, width and length of the flight corridor should be determined. In the process of determining the flight corridor, the impact of aircraft noise on the surrounding environment should also be taken into account. The noise propagation model should be used to evaluate the noise impact of aircraft passing through different areas, and professional equipment should be used to measure and collect the noise data generated by aircraft passing through air corridors at different altitudes above the ground in villages or densely populated areas. The relationship between the noise data and the height of the flight corridor above the ground should be analyzed to find an optimal height above the ground. The height, width and length of the flight corridor from the ground should be finally determined based on the geographical location of the airport and the surrounding environmental factors. The height, width and length of the flight corridor from the ground should be determined based on terrain data and 3D maps.

[0042] An air traffic control system includes a receiving unit and a transmission unit. The receiving unit is used to receive synchronous data of the longitude and latitude, height from the ground, own height, width and length of the flight corridor. The transmission unit is used to transmit the synchronous data to the aircraft so that the pilot can quickly understand the information of the current flight corridor and judge whether his own track is within the corridor.

[0043] In this embodiment, a flight test is designed to evaluate the differences in efficiency, safety, fuel consumption, flight time and communication complexity in air traffic management between the use of flight corridors and the traditional tower command mode. Two commercial airliners of the same model are used as test objects. Two test tracks are set up in an airspace with an altitude of 1,800 meters above the ground and a straight length of 5,000 meters. The first flight track is 1,500 meters above the ground and has an altitude of 700 meters. It is named Flight Corridor 1. The second flight track is 2,500 meters above the ground and has an altitude of 700 meters. The tower commands the commercial airliners to fly 50 times on the test tracks. A data recording system will be installed on the commercial airliners to record all relevant data during the flight, including fuel consumption, flight time, communication records, deviations from the flight path, and any changes in flight instructions. At the same time, professional noise monitoring equipment will be installed on the ground, and the trigger value of the noise event is set at 60dB to monitor the noise events generated by the commercial airliners during flight.

[0044] The test results of the above flight test are as follows:

[0045] 1. In actual flight tests, two aircraft can fly simultaneously in Flight Corridor 1 and Flight Corridor 2 at the same time, doubling the flight efficiency. At the same time, since the corridors are set at different altitudes and do not overlap with each other, the risk of collision during flight is greatly reduced, and congestion and chaos in the airspace is also avoided.

[0046] 2. The aircraft flies according to the pre-set flight corridor and does not need to contact the tower frequently. By comparing the communication records and command data, it was found that the incidence of communication misunderstandings and erroneous commands was reduced by 25%.

[0047] 3. By measuring the ambient noise with professional noise equipment, it was found that when the trigger value of the noise event was set at 60dB, the number of noise events generated through flight corridor 1 was reduced by 10% compared with the number of noise events generated through tower control to the test track.

[0048] 4. Comparing the deviation data of flight time and flight path, entering the designated route through the air corridor is 30% shorter in time and 5% shorter in path than entering the test track through tower control.

[0049] 5. Comparing the fuel consumption data, entering the designated route through the air corridor saves 5% of fuel than entering the designated route through tower control.

[0050] Example 2

[0051] like Figure 3-6 As shown, a flight corridor software includes a processing unit and a transmission unit, the transmission unit is used to transmit the synchronous data of the longitude and latitude, height from the ground, own height, width and length of the flight corridor to the air traffic control system, and the processing unit is used to execute modification instructions on the longitude and latitude, height from the ground, own height, width and length of the air corridor.

[0052] The steps of using the flight corridor in this embodiment are to set the corridor - query the track - select the corridor - analyze the track - display the analysis results, wherein setting the corridor is to go to the corridor setting page (such as Figure 3 and Figure 4 ), click the "New" button, fill in the corridor information, and click "OK" to complete the corridor setting. To query the track, click "Track Query" (such as Figure 5 ), select the query condition, click "Query", and analyze the track by checking "Corridor" in the gate list, analyzing the track information passing through the corridor and displaying it on the GIS map; (such as Figure 6 ), analyze the deviation from the track.
