Abstract
Description
Technical Field
[0001] This invention belongs to the field of airborne avionics systems technology, specifically relating to an integrated airborne air traffic control service processing system that supports air-to-ground and air-to-air collaborative operations, providing the necessary temporary air traffic control services for aircraft operations. Background Technology
[0002] With the transformation of air traffic management and the enhancement of aircraft capabilities, aviation will change from a traditional object controlled by air traffic control services to an important participant in air traffic control activities. This requires aircraft to have certain air traffic control service capabilities in order to achieve autonomous air traffic control service functions for air-to-ground and air-to-air collaborative operations.
[0003] Current airborne systems, such as the flight management subsystem, have the ability to manage flight plans, but do not yet have autonomous control service functions; other existing airborne subsystems, as well as multiple airborne subsystems, also do not yet have this function.
[0004] In addition, the International Civil Aviation Organization (ICAO) in its "Airborne Surveillance Applications Manual" (Doc 9994) and the Radio Technical Committee on Aviation (RTCA) in its "Minimum Aviation System Performance Standards for Aircraft Surveillance Applications (ASA)" (Do 289) and "Minimum Operational Performance Standards (MOPS) for Aircraft Surveillance Applications System (ASAS)" (Do 317) proposed the "Airborne Surveillance and Separation Assurance Processing Procedure" (ASSAP) function based on airspace traffic data such as ADS-B IN, TCAS, ADS-R, and TIS-B, providing discrete processing functions based on each application.
[0005] With the further advancement of airspace reform, control-based free operation will become an important mode of future aviation operations. However, existing airborne systems, and the functional definitions of the "Airborne Surveillance and Separation Assurance Procedure" (ASSAP), only consider airspace traffic and cannot address the service capacity requirements under mixed traffic, weather, and terrain conditions, thus failing to support future operational needs. Furthermore, airborne systems based on ASSAP lack an effective integrated application processing method; each application is processed separately, resulting in higher requirements for airborne resources and increased hardware costs. Summary of the Invention
[0006] The purpose of this invention is to provide an integrated air traffic control service processing system that supports air-to-ground and air-to-air collaborative operations, meeting the comprehensive service capability requirements for aircraft operations brought about by future changes in aviation operation modes.
[0007] The objective of this invention is achieved through the following technical solution:
[0008] An integrated airborne air traffic control service processing system that supports air-to-ground and air-to-air collaborative operations includes an airspace multi-situation integration module, a temporary air traffic control service operation plan generation module, and a temporary air traffic control service operation plan negotiation module.
[0009] The airspace multi-dimensional situational awareness module combines real-time and / or predicted traffic data, real-time and / or predicted meteorological data, and / or terrain data with the ongoing onboard operational plan or an operational plan to be confirmed to support the temporary operation of the aircraft to generate comprehensive situational awareness data.
[0010] When the onboard temporary air traffic control service operation plan generation module determines that an operation plan supporting the onboard temporary operation needs to be regenerated based on comprehensive situational data, it establishes an operation plan supporting the onboard temporary operation that considers the potential conflict risk level and avoids potential conflicts in the spatiotemporal area based on the comprehensive situational data of traffic, weather, and terrain based on the current planned flight path, and based on the set conflict avoidance strategy. The operation plan supporting the onboard temporary operation that needs to be regenerated is then output to the onboard temporary air traffic control service operation plan negotiation module for negotiation with the ground control service system and the airborne systems of other aircraft. Based on the feedback information from the onboard temporary air traffic control service operation plan negotiation module, it is either converted into an onboard operation plan that is being executed or a new operation plan supporting the onboard temporary operation that needs to be regenerated.
[0011] Furthermore, the process of generating comprehensive situational data by the airspace multi-situation integration module includes the following steps: A1) Based on the acquired airspace traffic information, meteorological target information, the ongoing onboard operation plan, or the operation plan to be confirmed to support the temporary operation of the onboard aircraft, identify traffic targets and meteorological targets that may be spatiotemporally related to the ongoing onboard operation plan or the operation plan to be confirmed to support the temporary operation of the onboard aircraft; A2) Analyze the subsequent operational intentions / plans of the identified traffic targets and meteorological targets that may be spatiotemporally related to the onboard aircraft's planned flight path to determine the information used to assess conflict risks; A3) Acquire the onboard aircraft's planned flight path and surrounding terrain, combine the acquired real-time meteorological target information and meteorological change forecast information, and combine the onboard aircraft's flight performance to determine the onboard aircraft's safe operating terrain envelope in the time dimension, and / or the onboard aircraft's safe operating terrain envelope information determined by other methods; A4) Integrate the information identified in A2) and A3) to form a comprehensive situational threat profile of traffic, meteorology, and terrain based on the current planned flight path; A5) After integrating the information generated in A4) with the acquired airspace traffic information and meteorological target information, generate comprehensive real-time or predicted comprehensive situational data of the airspace.
[0012] Furthermore, when the local temporary control service operation plan generation module receives operation adjustment information output by the ground control service system, it determines, based on the operation adjustment information, an adjusted operation plan to be confirmed to support the local temporary operation within the safe operation terrain envelope in the time dimension and / or the local safe operation terrain envelope determined by other methods.
[0013] Furthermore, when the onboard temporary air traffic control service operation plan generation module generates a new operation plan to be confirmed for supporting onboard temporary operations, and the onboard temporary air traffic control service operation plan to be confirmed for supporting onboard temporary operations is determined by the comprehensive situation data output by the airspace multi-dimensional situation integration module to no longer require the generation of a new operation plan to be confirmed for supporting onboard temporary operations, the module outputs the operation plan to be confirmed for supporting onboard temporary operations to other onboard equipment for plan display and / or plan execution. The onboard temporary air traffic control service operation plan generation module receives confirmation / revision or creation of the operation plan to be confirmed for supporting onboard temporary operations from downstream equipment or the airborne equipment for plan display and / or plan execution. The onboard temporary air traffic control service operation plan generation module sends the revised or created operation plan to support onboard temporary operations to the airspace multi-dimensional situation integration module to regenerate the comprehensive situation data and determine whether it is necessary to continue generating a new operation plan to be confirmed for supporting onboard temporary operations. After confirming that no new operation plan to be confirmed for supporting onboard temporary operations will be generated, the module outputs the operation plan to be confirmed for supporting onboard temporary operations to the onboard temporary air traffic control service operation plan negotiation module according to the aforementioned functions.
[0014] Furthermore, after receiving feedback information from the local temporary control service operation plan negotiation module, the local temporary control service operation plan generation module executes the following actions based on the feedback information:
[0015] Feedback Information Scenario 1: When the feedback information is the feasibility of the execution plan that supports temporary local operation to be confirmed, and the feasibility is in the executable state, the local temporary control service execution plan generation module will change the current execution plan that supports temporary local operation to be confirmed to the local execution plan that is currently being executed.
[0016] Feedback Information Scenario 2: When the feedback information is a modification suggestion for the operation plan to be confirmed to support the temporary operation of the local machine, the local temporary control service operation plan generation module regenerates the operation plan to be confirmed to support the temporary operation of the local machine based on the feedback information; and then outputs it to the local temporary control service operation plan negotiation module to wait for new feedback information.
[0017] Feedback Scenario 3: When the feedback information is an operational plan supporting temporary operations of the local aircraft, generated by the ground control service system or the airborne system of another aircraft and pending confirmation, the local temporary control service operational plan generation module outputs the operational plan to be confirmed to the airspace multi-dimensional situation integration module; then it receives the integrated situation data output by the airspace multi-dimensional situation integration module; if the operational plan to be confirmed is deemed executable based on the integrated situation data, the local temporary control service operational plan generation module changes the current operational plan to be confirmed to the currently executing local operational plan; if the operational plan to be confirmed is deemed unexecutable, a new operational plan to be confirmed is generated and then output to the local temporary control service operational plan negotiation module.
[0018] Furthermore, the onboard temporary air traffic control service operation plan generation module outputs the currently executing onboard operation plan to downstream onboard equipment for plan display and / or plan execution; at the same time, it further processes the currently executing onboard operation plan to generate information to guide the crew in making aircraft operation recommendations, as well as operation guidance information, which is output to downstream onboard equipment for operation information display, and / or auxiliary operation, and / or equipment execution.
[0019] The temporary air traffic control service operation plan generation module outputs an operation plan that supports temporary air traffic control operations or an operational plan that is currently being executed to the airspace multi-situation integration module through the fifth information interface; and outputs an operation plan that supports temporary air traffic control operations and receives feedback information to the temporary air traffic control service operation plan negotiation module through the second information interface.
[0020] The airspace multi-situation integration module outputs integrated situational data to the local temporary air traffic control service operation plan generation module through the first information interface; and receives real-time and / or predicted traffic data, real-time and / or predicted meteorological data, and / or terrain data in real time through the seventh information interface.
[0021] The on-board temporary air traffic control service operation plan negotiation module outputs the operation plan to be confirmed to support the on-board temporary operation of the on-board unit to the ground air traffic control service system, other aircraft's onboard systems, and receives feedback information through the sixth information interface.
[0022] Furthermore, the onboard temporary air traffic control service operation plan generation module directly outputs the onboard operation plan being executed to other onboard equipment downstream for plan display and / or plan execution via the third information interface; and outputs the information and / or operation guidance information generated by further processing the onboard operation plan being executed to other onboard equipment downstream for operation information display, and / or auxiliary operation, and / or equipment execution via the fourth information interface.
[0023] The beneficial effects of this invention are as follows:
[0024] (1) The airborne control service integrated processing system that supports air-ground and air-to-air coordinated operation described in this invention can work with other airborne systems to solve the problem of providing the required services under mixed traffic, weather and terrain conditions;
[0025] (2) The integrated airborne control service processing system that supports air-to-ground and air-to-air coordinated operation described in this invention establishes an effective processing method that makes good use of limited airborne system resources, which will reduce the cost of airborne equipment and help the development of domestically produced airborne equipment. Attached Figure Description
[0026] Figure 1 A schematic diagram of the structure of an integrated air traffic control service processing system to support air-to-ground and air-to-air coordinated operations. Detailed Implementation
[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The scope of protection of the present invention is not limited to the following embodiments.
[0028] See Figure 1As shown in the figure, the airborne air traffic control service integrated processing system 3 supporting air-to-ground and air-to-air collaborative operations in this embodiment includes an airspace multi-situation integration module 4, a local temporary air traffic control service operation plan generation module 6, a local temporary air traffic control service operation plan negotiation module 5, a first information interface 10 between the airspace multi-situation integration module 4 and the local temporary air traffic control service operation plan generation module 6, a second information interface 9 between the local temporary air traffic control service operation plan generation module 6 and the local temporary air traffic control service operation plan negotiation module 5, a third information interface 12 for outputting local temporary air traffic control service operation plan service human-machine interface information, and a fourth information interface 13 for outputting local temporary air traffic control service operation plan information.
[0029] The airspace multi-dimensional situational awareness module generates comprehensive situational awareness data based on traffic data, meteorological data, and terrain data, which is spatiotemporally related to the plans to be executed by the machine and the planned flight path, for subsequent processing.
[0030] The onboard temporary air traffic control service operation plan generation module 6 receives integrated situational data output from the airspace multi-situation integration module 4, or receives operation adjustment information directly or indirectly output by the ground control service system or other aircraft's onboard system 14 through the fifth information interface 7, and determines whether it is necessary to change the current operation plan and planned flight track. When it is determined that a change is necessary, an operation plan supporting the onboard temporary operation is generated for confirmation based on the set rules and requirements. After determining the onboard operation plan being executed, the module generates plan information and guides the crew to display aircraft operation operation information, and / or auxiliary operations, and / or equipment execution information, and outputs it to the downstream onboard system for application.
[0031] The local temporary air traffic control service operation plan negotiation module 5 is used to receive the operation plan to be confirmed for the local temporary operation generated by the local temporary air traffic control service operation plan generation module 6, and send it to the ground control service system and the other aircraft's onboard system 14; and to receive the feedback information on the operation plan to be confirmed for the local temporary operation sent by the ground control service system and the other aircraft's onboard system 14, and forward it to the local temporary air traffic control service operation plan generation module 6.
[0032] The first information interface 10 is used for the transmission of integrated situation data between the airspace multi-situation integration module 4 and the local temporary control service operation plan generation module 6.
[0033] The second information interface 9 is used for the transmission of unconfirmed operation plans supporting local temporary operation and feedback information of unconfirmed operation plans supporting local temporary operation between the local temporary control service operation plan generation module 6 and the local temporary control service operation plan negotiation module 5.
[0034] The third information interface 12 is used by the local temporary control service operation plan generation module 6 to output the plan data information of the local temporary control service operation plan and the human-machine interface driving information for the plan data display.
[0035] The fourth information interface 13 is used by the temporary air traffic control service operation plan generation module 6 to output the temporary air traffic control service operation plan to guide the crew in displaying aircraft operation information and / or auxiliary operations and / or equipment execution information.
[0036] The fifth information interface 16 is used to transmit operation plan information supporting temporary local operation that needs to be confirmed between the airspace multi-situation integration module 4 and the local temporary control service operation plan generation module 6.
[0037] Other modules and information interfaces will use existing airborne system equipment and equipment interfaces, and related content is not within the scope of this invention.
[0038] The detailed relationships between the above system components are as follows:
[0039] The aforementioned airspace multi-dimensional situational awareness module 4 combines real-time and predicted traffic data, real-time and predicted meteorological data, and terrain data with the onboard plans and planned flight paths to generate comprehensive situational awareness data.
[0040] Among them, (P0) the local plan to be executed and the planned track are output by the local temporary control service operation plan generation module 6 through the fifth information interface 16 between the airspace multi-situation integration module 4 and the local temporary control service operation plan generation module 6, and are operation plans that support local temporary operation to be confirmed or local operation plans that are being executed.
[0041] Real-time and predicted traffic data, real-time and predicted meteorological data, and terrain data are acquired directly by airborne equipment 1, or obtained by airborne equipment 1 after acquiring relevant data and then fusing them.
[0042] The process of generating comprehensive situational awareness data includes the following steps: A1) Based on the acquisition of traffic information, meteorological target information, and the aircraft's pending plans and planned flight paths in the designated airspace, identify traffic targets and meteorological targets that may be spatiotemporally related to the aircraft's pending plans and planned flight paths; A2) Analyze the subsequent operational intentions / plans of the identified traffic targets and meteorological targets that may be spatiotemporally related to the aircraft's planned flight paths to determine the targets that may conflict with the aircraft's planned flight paths, the potential conflict risk level, the spatiotemporal area of the potential conflict, and other information used to assess the conflict risk; A3) Acquire the aircraft's planned flight path and surrounding terrain, combine the acquired real-time meteorological target information and meteorological change prediction information, and combine the aircraft's flight performance to determine the aircraft's safe operating terrain envelope in the time dimension, and / or the aircraft's safe operating terrain envelope information determined by other methods; A4) Integrate the information identified in A2) and A3) to form a comprehensive situational awareness of traffic, meteorological, and terrain threats based on the current planned flight path; A5) After integrating the information generated in A4) with the acquired traffic information and meteorological target information in the designated airspace, generate comprehensive real-time or predicted comprehensive situational awareness data for the airspace.
[0043] The comprehensive situational data output by the airspace multi-dimensional situational intelligence module 4 is transmitted to the temporary air traffic control service operation plan generation module 6 via the first information interface 10 between the airspace multi-dimensional situational intelligence module 4 and the temporary air traffic control service operation plan generation module 6. The comprehensive situational data includes airspace area division information; this airspace area division information is based on airspace characteristic data generated from real-time or predicted airspace traffic data, meteorological data, and terrain data, and is divided into airspace areas according to their impact on aircraft airworthiness.
[0044] The local temporary control service operation plan generation module 6 outputs the currently executing local operation plan or the operation plan supporting local temporary operation that is yet to be confirmed through the fifth information interface 16 between the airspace multi-situation integration module 4 and the local temporary control service operation plan generation module 6.
[0045] The pending confirmation of the operational plan supporting temporary local operation can be determined based on comprehensive situational data to determine whether a new operational plan supporting temporary local operation needs to be generated. The comprehensive situational data is the comprehensive situational data output by the airspace multi-dimensional situational integration module 4 through the first information interface 10 from the local temporary air traffic control service operational plan generation module 6.
[0046] The pending confirmation of the operational plan supporting temporary operation of the local aircraft can also be based on the operational adjustment information to determine whether a new pending confirmation operational plan supporting temporary operation of the local aircraft needs to be generated. The operational adjustment information is output directly or indirectly by the ground control service system and the airborne system of other aircraft 14 through the fifth information interface 7.
[0047] When the local temporary control service operation plan generation module 6 determines that a new operation plan to be confirmed to support local temporary operation needs to be generated, it will execute according to the following operation plan adjustment judgment:
[0048] Scenario 1 for adjusting the operation plan: When the temporary air traffic control service operation plan generation module 6 does not receive operation adjustment information output by the ground air traffic control service system, the temporary air traffic control service operation plan generation module 6, based on the comprehensive situational data of the acquired airspace real-time or expected comprehensive situational data, the comprehensive situational data of traffic, weather, and terrain threats based on the current planned flight path, and based on the set conflict avoidance strategy, establishes an unconfirmed operation plan to support the temporary operation of the local aircraft in the spatiotemporal area that considers the potential conflict risk level and avoids potential conflicts.
[0049] Situation 2 where the operation plan needs adjustment: When the local temporary control service operation plan generation module 6 receives operation adjustment information output by the ground control service system, the local temporary control service operation plan generation module 6 determines the adjusted operation plan to be confirmed to support the local temporary operation based on the operation adjustment information, within the safe operation terrain envelope in the time dimension, and / or the local safe operation terrain envelope determined by other methods.
[0050] The temporary air traffic control service operation plan generation module 6 generates an operation plan that supports temporary air traffic control operations and is awaiting confirmation. The plan is then output to the airspace multi-situation integration module 4 via the fifth information interface 16 between the airspace multi-situation integration module 4 and the temporary air traffic control service operation plan generation module 6.
[0051] When the local temporary air traffic control service operation plan generation module 6 generates a new operation plan to be confirmed to support local temporary operation, and the operation plan to be confirmed to support local temporary operation is determined based on the comprehensive situation data output by the airspace multi-situation integration module 4 to no longer require the generation of a new operation plan to be confirmed to support local temporary operation, the local temporary air traffic control service operation plan generation module 6 can output the operation plan to be confirmed to support local temporary operation to the local temporary air traffic control service operation plan negotiation module 5 through the second information interface 9 between the local temporary air traffic control service operation plan generation module 6 and the local temporary air traffic control service operation plan negotiation module 5.
[0052] Furthermore, when the temporary air traffic control service operation plan generation module 6 generates a new operation plan to be confirmed for supporting temporary air traffic control operations, and the operation plan to be confirmed for supporting temporary air traffic control operations is determined by the comprehensive situation data output by the airspace multi-dimensional situation integration module 4 to no longer require the generation of a new operation plan to be confirmed for supporting temporary air traffic control operations, the module outputs the operation plan to be confirmed for supporting temporary air traffic control operations to the other onboard equipment 2 for plan display and / or plan execution through the second information interface 12 between the temporary air traffic control service operation plan generation module 6 and the other onboard equipment 2 for plan display and / or plan execution. Downstream equipment or crew processes the operation plan to be confirmed for supporting temporary air traffic control operations through the other onboard equipment for plan display and / or plan execution. After revision, the onboard temporary air traffic control service operation plan generation module 6 receives confirmation / revision or creation of the operation plan supporting the onboard temporary operation from the new downstream equipment or crew through the second information interface 12 via the plan display and / or other onboard equipment of the plan execution; the onboard temporary air traffic control service operation plan generation module sends the revised or created operation plan supporting the onboard temporary operation to the airspace multi-situation integration module 4 according to the aforementioned function, and re-verifies it according to the aforementioned function of the onboard temporary air traffic control service operation plan generation module 6; after confirming that no new operation plan supporting the onboard temporary operation will be generated, the operation plan supporting the onboard temporary operation will be output to the onboard temporary air traffic control service operation plan negotiation module 5 according to the aforementioned function.
[0053] After receiving feedback information from the local temporary control service operation plan generation module 5 through the second information interface 9 between the local temporary control service operation plan generation module 6 and the local temporary control service operation plan negotiation module 5, the local temporary control service operation plan generation module 6 executes the following based on the feedback information:
[0054] Feedback Information Scenario 1: When the feedback information is the feasibility of the operation plan supporting the temporary operation of the aircraft to be confirmed, and the feasibility is in the executable state, the temporary air traffic control service operation plan generation module 6 changes the current operation plan to be confirmed to the current temporary operation plan of the aircraft to be executed, and then outputs it directly to the downstream onboard equipment 2 for plan display and / or plan execution through the third information interface 12; at the same time, it further processes the executing onboard operation plan to generate information to guide the crew to make suggestions for aircraft operation operations, as well as operation guidance information, and outputs it to the downstream onboard equipment 15 for operation information display, and / or auxiliary operation, and / or equipment execution through the fourth information interface 13;
[0055] Feedback Information Scenario 2: When the feedback information is a modification suggestion for the operation plan to be confirmed to support the temporary operation of the local machine, the local temporary control service operation plan generation module 6 regenerates the operation plan to be confirmed to support the temporary operation of the local machine based on the feedback information; then, the operation plan to be confirmed to support the temporary operation of the local machine is output to the local temporary control service operation plan negotiation module 5 through the second information interface 9.
[0056] Feedback Information Scenario 3: When the feedback information is an operational plan supporting temporary operations of the local aircraft generated by the ground control service system and the other aircraft's onboard system 14, which is pending confirmation, the local temporary control service operational plan generation module 6 outputs to the airspace multi-dimensional situation integration module 4 through the fifth information interface 16 between the airspace multi-dimensional situation integration module 4 and the local temporary control service operational plan generation module 6; then it receives the comprehensive situation data output by the airspace multi-dimensional situation integration module 4 through the first information interface 10; when the local temporary control service operational plan supporting temporary operations of the local aircraft is determined to be executable based on the comprehensive situation data, the local temporary control service operational plan generation module 6 changes the current operational plan supporting temporary operations of the local aircraft to the currently executing local operational plan. The plan is then directly output to other onboard equipment 2 downstream for plan display and / or plan execution via the third information interface 12; simultaneously, the executing onboard operation plan is further processed to generate information guiding the crew to perform aircraft operation operations, as well as operation guidance information, and is output to other onboard equipment 15 downstream for operation information display, and / or auxiliary operation, and / or equipment execution via the fourth information interface 13; when the operation plan to be confirmed supporting the temporary onboard operation is in an unexecutable state, a new operation plan to be confirmed supporting the temporary onboard operation is generated; then, the operation plan to be confirmed supporting the temporary onboard operation is output to the onboard temporary air traffic control service operation plan negotiation module 5 via the second information interface 9.
[0057] The executing local operation plan and the operation plan to be confirmed supporting local temporary operation generated by the local temporary control service operation plan generation module 6 include, but are not limited to, operation plans that maintain and / or adjust the spatiotemporal relative positional relationship with moving targets in the airspace, and operation plans that maintain and / or adjust the spatiotemporal absolute positional relationship with fixed targets in the airspace.
[0058] The on-the-ground operation plan generated by the on-the-ground temporary air traffic control service operation plan generation module 6 can be directly or manually converted into the on-the-ground equipment data of the operation plan used by the airborne flight management system.
[0059] The pending operation plan for supporting temporary local operation generated by the local temporary control service operation plan generation module 6 may be a single set of information or multiple sets of information.
[0060] The on-site temporary air traffic control service operation plan negotiation module 5 receives the pending operation plan supporting the on-site temporary operation generated by the on-site temporary air traffic control service operation plan generation module 6 through the second information interface 9, and outputs it to the ground control service system and the other aircraft's onboard system 14 through the sixth information interface 11. The on-site temporary air traffic control service operation plan negotiation module 5 receives feedback information such as the feasibility of the pending operation plan supporting the on-site temporary operation output by the ground control service system and the other aircraft's onboard system 14 through the sixth information interface 11, and sends this feedback information back to the on-site temporary air traffic control service operation plan generation module 6 through the second information interface 9.
[0061] The feedback information output by the ground control service system and the other aircraft's onboard system 14 through the sixth information interface 11 may include the following: (1) the feasibility of the operation plan that supports the temporary operation of the local aircraft to be confirmed; (2) the modification suggestions for the operation plan that supports the temporary operation of the local aircraft to be confirmed; and (3) the operation plan that supports the temporary operation of the local aircraft generated by the ground control service system and the other aircraft's onboard system 14 to be confirmed.
[0062] The aforementioned system functions will operate in accordance with, but not limited to, the steps described below.
[0063] Step 1: During aircraft operation, the airspace multi-situation integration module 4 receives real-time and / or predicted airspace traffic information, real-time and / or predicted airspace meteorological target information, and terrain information from onboard equipment via the seventh information interface 8; the temporary air traffic control service operation plan generation module 6 outputs the currently executing local operation plan or the operation plan supporting the temporary local operation to the airspace multi-situation integration module 4 via the fifth information interface 16, and then executes Step 2.
[0064] Step 2: The airspace multi-situation integration module 4 integrates the information received in Step 1 according to the following sub-steps: 21) Based on the acquired traffic information, meteorological target information, and the aircraft's planned and scheduled flight paths in the designated airspace, the module identifies traffic and meteorological targets within a specified distance range around the planned flight path point, using the planned arrival time of the aircraft as the benchmark; 22) The module analyzes the subsequent operational intentions / plans of the identified traffic and meteorological targets that may be spatiotemporally related to the aircraft's planned flight path, determines the potential existence of targets with less than the spatially permissible threshold along the aircraft's planned flight path, and determines the potential conflict risk level and the potential conflicts established based on the aircraft's planned flight path and / or the target's planned flight path. Information such as spatiotemporal regions is used to assess conflict risk; 23) Obtain the planned flight path and surrounding terrain of the aircraft, combine the acquired real-time meteorological target information and meteorological change forecast information, and combine the real-time flight performance of the aircraft and / or the real-time flight performance at the expected time, to determine the safe operating terrain envelope of the aircraft in the time dimension and / or the safe operating terrain envelope information of the aircraft determined by other methods within a certain margin range; 24) Integrate the information identified in 22) and 23) to form a comprehensive situation of traffic, meteorology, and terrain threats based on the current planned flight path; 25) After splicing and integrating the information generated in 21) to 24) with the acquired traffic information and meteorological target information within the designated airspace, a comprehensive real-time or expected comprehensive airspace situation is generated. Output the generated comprehensive situation data to the temporary air traffic control service operation plan generation module 6, and execute step three or step four.
[0065] Step 3: The local temporary control service operation plan generation module 6 receives the comprehensive situation data output by the airspace multi-dimensional situation integration module 4 based on the currently executing local operation plan or the operation plan to be confirmed to support the local temporary operation, and then executes Step 5.
[0066] Step four: The temporary air traffic control service operation plan generation module 6 receives the operation adjustment information output by the ground air traffic control service system and the other aircraft's onboard system 14 through the fifth information interface 7, and then executes step five.
[0067] Step 5, Local Temporary Control Service Operation Plan Generation Module 6: 51) Based on the comprehensive situational data generated in Step 3, determine whether the potential conflict risk level of the currently executing local operation plan is acceptable; if the risk level is acceptable, proceed to Step 1; if the risk level is unacceptable, proceed to Step 6; 52) Based on the comprehensive situational data generated in Step 3, determine whether the potential conflict risk level of the operation plan to be confirmed to support the local temporary operation is acceptable; if the risk level is acceptable, proceed to Step 9; if the risk level is unacceptable, proceed to Step 6; 53) Determine the impact of the operation adjustment information received in Step 4 on the currently executing local operation plan; if the impact is within an acceptable range, proceed to Step 4; if the impact is within an unacceptable range, proceed to the preferred Step 7.
[0068] Step 6: The temporary air traffic control service operation plan generation module 6, based on the comprehensive situation of the acquired airspace in real time or as expected, and the comprehensive situation of traffic, weather, and terrain threats based on the current planned flight path, establishes an operation plan to support the temporary operation of the aircraft, according to the established planned flight path adjustment strategy, such as the shortest time and the smallest deviation from the original flight path. This plan prioritizes conflict spatiotemporal areas that avoid high-risk targets in space and conflict spatiotemporal areas that prioritize avoiding medium- and low-risk targets in time.
[0069] Step 7: The temporary air traffic control service operation plan generation module 6, based on the operation adjustment information, the safe operation terrain envelope of the aircraft in the time dimension in the real-time or expected comprehensive situation of the airspace, and / or the safe operation terrain envelope of the aircraft determined by other methods, determines the adjusted operation plan to be confirmed to support the temporary operation of the aircraft according to the operation adjustment information, the established adjustment rules (such as time priority, space priority, etc.) or the suggestion information.
[0070] Step 8: The temporary air traffic control service operation plan generation module 6 outputs the operation plan for supporting temporary air traffic control services generated in Step 6 or Step 7 to the airspace multi-situation integration module 4 through the fifth information interface 16 between the airspace multi-situation integration module 4 and the temporary air traffic control service operation plan generation module 6. The operation plan for supporting temporary air traffic control services generated in Step 6 or Step 7 is to be confirmed and output to the airspace multi-situation integration module 4. Step 1 is then executed.

[0072] Preferably, in step ten, the local temporary control service operation plan generation module 6, based on the confirmation and / or revision information of the operation plan to be confirmed supporting the local temporary operation received in step nine; when revision information is received, the operation plan to be confirmed supporting the local temporary operation is updated, and step two is executed; when confirmation information is received and it is confirmed, step eleven is executed; when confirmation information is received and it is a recalculation, step five is executed.
[0073] Step 11: The local temporary air traffic control service operation plan negotiation module 5 outputs the operation plan to be confirmed to support the local temporary operation to the ground control service system and the other aircraft's onboard system 14 through the sixth information interface 11, and listens for feedback information from the ground control service system and the other aircraft's onboard system 14 through the sixth information interface 11; when feedback information from the ground control service system and the other aircraft's onboard system 14 through the sixth information interface 11 is heard, step 12 is executed.
