It can be implemented only after being approved. Once implemented, the demarcated airspace will not be changed within a certain period of time until it is no longer in use.

[0003] Currently, only one airspace is demarcated according to the flight plan, and the entire airspace will be occupied during the flight. In this case, if the aircraft using the airspace does not fully execute the submitted flight plan or the demarcation of the temporary airspace is unreasonable, there will be a great waste of relevant airspace resources, and it is not conducive to the relevant control of other aircraft, resulting in low utilization efficiency of the airspace.

[0044] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] The present invention provides a temporary airspace demarcation method, Figure 1 is the first of the schematic flowcharts of the temporary airspace demarcation method provided by the present invention, as Figure 1 shown, the method includes:

[0046] Step S101, obtaining the flight plan of the aircraft;

[0047] Step S102, connecting all the waypoints in the flight plan to obtain an initial polygonal airspace;

[0048] Step S103, demarcating a plurality of initial temporary airspaces at each waypoint according to different types of flight missions;

[0049] Step S104, merging the plurality of initial temporary airspaces at each waypoint with the initial polygonal airspace into a polygonal airspace;

[0050] Step S105, based on the predicted altitude upper and lower limits of the aircraft at each waypoint, dividing the polygonal airspace into temporary airspaces at each altitude layer.

[0051] Specifically, obtain the submitted flight plan and conduct inspections, such as flight plan verification and flight permission registration. Connect all the waypoints included in the flight plan to form a closed polygon, set the altitude range according to the flight plan, and use this polygon as the initial polygon airspace. In addition, for each waypoint in the flight plan, multiple initial temporary airspaces are demarcated according to different types of flight missions. On this basis, the multiple initial temporary airspaces of each waypoint can be merged with the aforementioned initial polygon airspace into a polygon airspace. It can be understood that the multiple initial temporary airspaces of each waypoint are within the scope of the entire initial polygon airspace. Here, different types of flight missions, in addition to including the missions provided by the flight plan itself, can also include other types of missions, such as reconnaissance, cruise, in-flight refueling, etc.

[0052] Each waypoint in the flight plan corresponds to an estimated time. The aircraft will pass through the waypoint at this estimated time. At this time, the upper and lower limits of the altitude at which the aircraft is expected to be can be used as an altitude layer to divide the polygon airspace, and the temporary airspace of this altitude layer is obtained. It can be understood that the polygon airspace includes two types of airspaces. Therefore, the temporary airspaces of the same altitude layer can also be divided into two types. The first type is the section of the polygon airspace on this altitude layer, including the temporary airspace covering all areas below this altitude layer. For example, if it is required for the aircraft to cruise at a certain altitude layer, this type of temporary airspace can be directly used at this time, without demarcating multiple airspaces; the second type is the temporary airspaces of different missions at each waypoint below this altitude layer, such as a fan-shaped warning area, a rectangular reconnaissance area, an in-flight refueling area, or an air corridor, etc.

[0053] It should be noted that by first demarcating the polygon airspace according to the flight plan and then subdividing the polygon airspace, this method of dividing the temporary airspace can achieve local reuse of the airspace without changing the overall demarcation of the airspace from the beginning, improving the utilization efficiency and flexibility of the temporary airspace. Flight plans are often bound to the use of airspace, and when multiple flight plans use the same airspace, it requires a controller to pay more attention. Therefore, the embodiment of the present invention combines the flight situation with the method of demarcating the temporary airspace, and can temporarily divide the airspace at each local waypoint, reducing the possibility of conflicts when multiple flight plans use the same airspace.

[0054] The method provided by the embodiment of the present invention obtains the initial polygon airspace by connecting all the waypoints in the flight plan, demarcates multiple initial temporary airspaces according to different types of flight missions at each waypoint, merges and generates the polygon airspace on this basis, and then subdivides the polygon airspace based on the upper and lower limits of the altitude expected by the aircraft at each waypoint, improving the utilization efficiency and flexibility of the temporary airspace, and at the same time reducing the possibility of conflicts when multiple flight plans use the same airspace.

[0055] Based on any of the above embodiments, after step S104, the following steps are further included:

[0056] Check whether there is a clear zone within the polygonal airspace;

[0057] If there is a clear zone, then use the polygonal airspace after excluding the clear zone as the updated polygonal airspace.

[0058] Specifically, after obtaining the merged polygonal airspace, no-fly zones and various types of obstacles affecting flight can be searched for within this polygonal airspace according to airspace clearance regulations. Further, if obstacles are found, circular airspaces with a preset radius can be constructed with the centers of various obstacles combined with the heights of the corresponding obstacles, and all the generated circular airspaces are counted as clear zones. If a no-fly zone is found, the no-fly zone is counted as a clear zone.

[0059] If there is a clear zone within the polygonal airspace, then exclude the clear zone within this polygonal airspace, and use the polygonal airspace after exclusion as the updated polygonal airspace. If there is no clear zone, then there is no need to update the polygonal airspace, and subsequent airspace subdivision can be directly performed according to this polygonal airspace.

[0060] Based on any of the above embodiments, S105 specifically includes:

[0061] Based on the upper and lower height limits expected by the aircraft at each waypoint, the upper and lower height limits of each type of controlled airspace, and the upper and lower height limits of the clear zone, divide the polygonal airspace into temporary airspaces at each height layer.

[0062] Specifically, in order to improve the accuracy and effectiveness of temporary airspace demarcation, the embodiments of the present invention combine the upper and lower height limits expected by the aircraft at each waypoint, the upper and lower height limits of each type of controlled airspace, and the upper and lower height limits of the clear zone to divide the polygonal airspace into temporary airspaces at each height layer. It should be noted that each temporary airspace has its own usage time and upper and lower height limits. All temporary airspaces do not conflict with each other. In the airspace demarcation plan containing multiple flight plans, each temporary airspace can only accommodate aircraft from the same flight plan.

[0063] The above-mentioned each type of controlled airspace can include four types: upper airspace control airspace, medium and low altitude control airspace, approach control airspace, and tower control airspace. The upper and lower height limits involved in each type of controlled airspace can include 6000 meters, 6600 meters, and the control height lower limits in different regions, etc. The clear zone can include no-fly zones and areas demarcated for various types of obstacles affecting flight, etc. For example, if the obstacle is a mountain, the lower height limit of the temporary airspace cannot be lower than the height of the mountain.

[0064] Based on any of the above embodiments, the present invention provides a method for managing temporary airspace based on flight situation Figure 2It is one of the schematic flowcharts of the temporary airspace management method provided by the present invention. As Figure 2 shown, the method includes:

[0065] S201 Based on the current flight track of the aircraft, determine the temporary airspace where the aircraft is currently located;

[0066] S202 Check whether there is a change in the flight mission of the aircraft. If there is a change, change the temporary airspace based on the changed flight mission;

[0067] S203 Activate the temporary airspace and the adjacent temporary airspaces adjacent to the temporary airspace. The temporary airspace and the adjacent temporary airspaces are delimited based on the temporary airspace delimitation method described in any of the above embodiments.

[0068] Specifically, according to the flight plan, delimit the temporary airspaces of each altitude layer according to the temporary airspace delimitation method described in any of the above embodiments. On this basis, obtain the current flight track of the aircraft based on the flight situation of the aircraft, determine the temporary airspace where the aircraft is currently located, obtain the flight mission of the aircraft, check whether there is a change in the flight mission of the aircraft. If there is a change, change the temporary airspace according to the changed flight mission information and notify. If there is no change, there is no need to change.

[0069] Then, it can be judged whether the temporary airspace is in a static state. If so, the temporary airspace and the adjacent temporary airspaces adjacent to the temporary airspace, that is, the temporary airspaces of adjacent altitude layers, can be activated to facilitate the flight of the aircraft and improve the efficiency of temporary airspace management.

[0070] It should be noted that if the temporary airspace is adjacent to the air corridor, the air corridor can be activated. If the temporary airspace belongs to the approach control area, the temporary airspace closest to the approach control area and the tower control area within the meta-polygon airspace can be activated. If the upper and lower limits of the height of the adjacent temporary airspace do not exceed the preset threshold, the adjacent temporary airspace can be further activated until the sum of the upper and lower limits of the height of the activated adjacent temporary airspace exceeds the preset threshold to ensure flight safety and efficiency. If necessary, the flight situations of multiple flight plans respectively occupy their own temporary airspaces, and this principle is still maintained during the change.

[0071] The method provided by the embodiment of the present invention combines the flight situation with the temporary airspace delimitation method, can temporarily divide the airspace at each local waypoint, improves the utilization efficiency and flexibility of the temporary airspace, can be used for multiple flight plans to reuse the temporary airspace resources, reduces the possibility of conflicts when multiple flight plans use the same airspace. On this basis, according to the temporary airspace where the aircraft is located, the temporary airspace and the temporary airspaces adjacent to the temporary airspace are activated, and the efficiency of temporary airspace management is improved.

[0072] Based on any of the above embodiments, after S203, the following steps are further included:

[0073] Detect the ADS-B (Automatic Dependent Surveillance-Broadcast) signal of the aircraft in the temporary airspace;

[0074] If the ADS-B signal of the aircraft is not detected within a preset duration, transfer the temporary airspace to a static state.

[0075] Specifically, considering that if there is an aircraft in the airspace, the aircraft will broadcast the ADS-B signal. Therefore, in order to further improve the utilization efficiency of the temporary airspace and avoid waste of airspace resources, in the embodiments of the present invention, when the temporary airspace is in an active state, the ADS-B signal of the aircraft can be detected in real time in the temporary airspace. If the ADS-B signal of the aircraft is not detected within a preset duration, it means that there is no aircraft, and the temporary airspace can be temporarily abandoned and transferred to a static state.

[0076] Here, the preset duration can be set as needed. For example, 15 minutes.

[0077] Based on any of the above embodiments, currently, the airspace delimited according to the flight plan includes all waypoints in the flight plan, and the entire airspace will be occupied during the flight process, resulting in low utilization efficiency of the airspace and a great waste of airspace resources. Although there are also some studies aiming to improve the utilization efficiency of the airspace, they focus more on the rules of airspace use, and the formulation of the rules is closely related to the aircraft itself, the object of use, and no improvement has been made to the existing airspace, and the problem of low utilization efficiency of the airspace still cannot be avoided. To solve the above problems, the present invention provides a method for delimiting and managing temporary airspace based on flight situation, which subdivides the entire large airspace of the flight plan according to the flight situation to obtain each meta-airspace. Therefore, for the entire large airspace, even if there are overlapping airspaces in multiple flight plans or overlapping points in terms of time points, as long as the meta-airspaces do not overlap, the utilization efficiency of the airspace is improved, local reuse of multiple flight plans is achieved, and the possibility of conflicts when multiple flight plans use the same airspace is avoided.

[0078] Figure 3 It is the second flow chart of the method for delimiting temporary airspace provided by the present invention. Figure 4 It is the second flow chart of the method for managing temporary airspace provided by the present invention. As Figure 3 and Figure 4 shown, the method for delimiting and managing temporary airspace based on flight situation includes the following steps:

[0079] Step 1: Check the submitted flight plan, conduct flight plan verification and flight permission registration, etc., automatically initiate takeoff and landing reports after takeoff and landing, and expect to force the aircraft to execute according to the flight plan.

[0080] Step 2: Designate the initial temporary airspace according to the flight plan and the rules for temporary airspace demarcation.

[0081] In Step 2, the flight plan involves various types of aircraft, including private aircraft, civilian drones, civil aviation, and commercial air transportation. The initial air corridor is demarcated initially according to the submitted flight plan, and the width can be set to 20 kilometers. The initial temporary airspace is demarcated according to the following rules:

[0082] Step 2-1: Connect all possible position points of the flight plan to form a closed initial polygonal airspace, and the height range is set according to the flight plan. At each waypoint, demarcate multiple possible airspaces according to different types of flight missions (not only including the missions submitted in the flight plan), and merge them with the aforementioned initial polygonal airspace into a polygonal airspace.

[0083] Step 2-2: Search for no-fly zones or various obstacles affecting flight within this polygonal airspace according to the airspace clearance regulations. If obstacles are found, circular airspaces can be constructed with a radius of 10 kilometers centered on each type of obstacle and combined with the height settings of the corresponding obstacles. All the generated circular airspaces are regarded as clearance areas. It can be understood that if a no-fly zone is found, the no-fly zone will also be regarded as a clearance area. Exclude the clearance areas within this polygonal airspace. The polygonal airspace after exclusion is called the meta-polygonal airspace. If there are no clearance areas, the polygonal airspace can be directly used as the meta-polygonal airspace.

[0084] Step 2-3: Limit by the heights of each position point (i.e., waypoints) of the flight plan, the heights involved in the classification of control airspaces, and the heights of clearance areas, divide the meta-polygonal airspace into multiple meta-airspaces, that is, the temporary airspaces at multiple height levels in Step S105. Each meta-airspace has its own usage time and upper and lower height limits. All meta-airspaces do not conflict with each other. In the airspace demarcation plan containing multiple flight plans, each meta-airspace can only accommodate flight situations from the same flight plan. Control airspaces can be divided into four categories: high-altitude control airspace, medium-low altitude control airspace, approach control airspace, and tower control airspace. The heights involved in the classification of control airspaces are 6000 meters, 6600 meters, and the lower limits of control heights in different regions. The meta-airspaces at the same height level are divided into two types. The first type includes the meta-airspaces covering the entire area below this height level; the second type is the specific meta-airspaces based on each waypoint. In addition to the tasks provided by the flight plan itself, airspaces assumed based on other types of tasks are also included, such as fan-shaped warning areas, rectangular reconnaissance areas, or air corridors, etc.

[0085] Step 3: Change the temporary airspace according to the execution of the flight plan in combination with the temporary airspace demarcation rules in Step 2 and notify.

[0086] The execution of the flight plan in Step 3 refers to the flight posture of the aircraft. According to the meta-airspace where the flight posture is located, activate this meta-airspace and the adjacent altitude meta-airspace. If there is an adjacent air corridor, activate the air corridor. The corresponding control measures rules are as follows:

[0087] Rule 3-1: Provide flight mission information when the flight posture is at a certain waypoint, judge whether there is a change. If there is a change, change the meta-airspace according to the corresponding mission change situation.

[0088] Rule 3-2: If this meta-airspace belongs to the approach control area, activate the meta-airspace within this meta-polygon airspace that belongs to the approach control area and the tower control area and is the closest.

[0089] Rule 3-3: If the height of the adjacent meta-airspace does not exceed 500 meters, further activate the adjacent meta-airspace until the upper and lower limits of the height of the adjacent airspace exceed 1000 meters.

[0090] Rule 3-4: If necessary, when multiple flight postures of different flight plans respectively occupy meta-airspaces, this principle is still maintained during the change.

[0091] Step 4: Judge whether the meta-airspace is in a static state. If so, activate this meta-airspace and the related meta-airspaces. For all activated meta-airspaces and adjacent activated meta-airspaces, judge whether the ADS-B signal of the aircraft can be detected within the meta-airspace, so as to judge whether there is a flight posture in the meta-airspace. If there is no flight posture for more than 15 minutes, transfer this meta-airspace to a static state.

[0092] The present invention provides a method for demarcating and managing a temporary airspace based on flight postures. First, it refines the basic demarcation methods of different types of airspaces, gives the attributes, demarcation principles, true altitude reference above the ground, objects of use and usage rules of the temporary airspace; sets up air corridors between airspaces for aircraft to use relevant airspaces, and proposes management measures during the flight process of the aircraft, such as reporting flight plans, automatically detecting flight rules, registering for flight permission, automatically reporting takeoff and landing, etc. The method for demarcating and managing the temporary airspace provided by the present invention significantly improves the utilization efficiency and flexibility of the temporary airspace.
