Description

Technical Field

[0001] This invention relates to the technical field of civil aviation airspace data processing, and in particular to a data link-based instruction consistency assessment device. Background Technology

[0002] In recent years, the increasing demand for passenger travel and the rapid growth of airspace traffic have led to a rise in flight conflicts, significantly increasing the workload of air traffic controllers and posing a serious threat to the efficient and safe operation of air traffic management. Existing automated air traffic control systems use real-time flight tracks, flight plans, and information from the BADA aircraft database to predict short-term flight paths and provide early warnings of command consistency. However, these methods only issue warnings when an aircraft deviates from its flight path and exceeds the warning threshold, resulting in a delay in conflict detection. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a data link-based instruction consistency assessment device, which realizes the consistency comparison between crew intentions and control instructions, assesses potential conflicts, and improves flight safety.

[0004] The technical solution of the present invention is: this data link-based instruction consistency assessment device includes: an air-to-ground data interaction and collaboration system, an air-to-ground interconnection and instruction consistency assessment system, and a data link flight instruction verification and intent extraction system;

[0005] The air-to-ground data interaction and collaboration system collects and processes the data required for system operation, providing data support for other modules; the air-to-ground interconnection and command consistency assessment system determines the timeliness of commands based on command type and continuously monitors the crew's intentions with a certain strategy; the data link flight command verification and intention extraction system collects and extracts crew intention information and high-precision track profile information in real time from the activated route and track profile data extracted from the airborne flight management system through the safety-type air-to-ground data link.

[0006] This invention utilizes a safety-type air-to-ground data link to acquire in real time the activated route information entered by the crew in the aircraft flight management system and the high-precision track profile information automatically calculated by the flight management system. It extracts the crew's intention commands and compares them with the digital commands issued by air traffic control, thereby achieving consistency comparison between crew intentions and air traffic control commands, identifying potential conflicts, and improving flight safety.

[0007] Figure 1 This is a schematic diagram of the instruction consistency assessment device based on the data link according to the present invention. Detailed Implementation

[0008] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0009] To make the description of this disclosure more detailed and complete, illustrative descriptions of embodiments and specific examples of the present invention are provided below; however, these are not the only forms of implementing or utilizing the specific examples of the present invention. The embodiments cover features of multiple specific examples, as well as the apparatus steps and their sequence for constructing and operating these specific examples. However, other specific examples may also be used to achieve the same or equivalent functions and sequence of steps.

[0010] The data link-based command consistency assessment device uses a safety-class air-to-ground data link to acquire in real time the active route information entered by the crew in the Flight Management System (FMS) and the high-precision track profile information automatically calculated by the FMS. It extracts the crew's intention commands and compares them with the digital commands issued by air traffic control, thereby achieving consistency comparison between the crew's intentions and air traffic control commands, assessing potential conflicts, and improving flight safety.

[0011] This device relies on the aircraft flight management system to extract crew intent based on activated routes and high-precision track profile information transmitted via a safety-class air-to-ground data link. The calculation of this information is combined with pre-set performance limits, flight plans, aircraft type information, load balance, and real-time atmospheric environmental data detected by the aircraft. It comprehensively calculates the optimal flight trajectory and estimated arrival times for each waypoint with high precision (second-level accuracy) by fully integrating information such as the air environment along the route, current load, crew intent, performance limits, and optimal track profile. The extracted crew intent includes information such as the currently activated route, offset, altitude, arrival / departure procedures, approach procedures, and runway information. It can be compared in real-time with air traffic control instructions. Compared to traditional ground control systems, this device advances instruction consistency judgment from in-process to pre-process, and from conflict analysis to intent analysis, solving the problems of lag in traditional automated ground control systems that rely on track analysis for conflict determination.

[0012] like Figure 1 As shown, this data link-based instruction consistency assessment device includes: an air-to-ground data interaction and collaboration system 100, an air-to-ground interconnection and instruction consistency assessment system 200, and a data link flight instruction verification and intent extraction system 300.

[0013] The air-to-ground data interaction and collaboration system collects and processes the data required for system operation, providing data support for other modules; the air-to-ground interconnection and command consistency assessment system determines the timeliness of commands based on command type and continuously monitors the crew's intentions with a certain strategy; the data link flight command verification and intention extraction system collects and extracts crew intention information and high-precision track profile information in real time from the activated route and track profile data extracted from the airborne flight management system through the safety-type air-to-ground data link.

[0014] This invention utilizes a safety-type air-to-ground data link to acquire in real time the activated route information entered by the crew in the aircraft flight management system and the high-precision track profile information automatically calculated by the flight management system. It extracts the crew's intention commands and compares them with the digital commands issued by air traffic control, thereby achieving consistency comparison between crew intentions and air traffic control commands, identifying potential conflicts, and improving flight safety.

[0015] Preferably, the air-to-ground data interaction and collaboration system realizes the data collection and processing required for system operation, and consists of a digital command acquisition module, a human factors analysis module, and a situation acquisition module. The digital command acquisition module collects controllers' digital control intentions. This module receives digital control commands from the existing ground control system and pushes them, such as arrival / departure procedures, approach procedures, runway instructions, diversion instructions, altitude adjustments, and speed adjustments, to the air-to-ground interconnection and command consistency assessment system, which then completes the digital control command push. The human factors analysis module dynamically analyzes the average operation delay from the completion of the digital control command push to the crew's completion of the command input in the flight management system based on the control command. It constructs historical big data on human factors analysis and dynamically evaluates the target crew's experience operation time by comprehensively considering multiple factors such as airline, aircraft type, flight management system model, and crew qualifications. It also provides possible monitoring cycles for the crew intention monitoring strategy judgment module of the air-to-ground interconnection and command consistency assessment system, so as to obtain the crew's intentions as early as possible and complete the consistency comparison. The situation acquisition module receives flight dynamics and flight plan information required for system operation and assists the data link flight command verification and intention extraction system's track passage time comparison module in completing high-precision track profile acquisition.

[0016] Preferably, the air-to-ground interconnection and command consistency assessment system determines the timeliness of commands based on their type and continuously monitors the crew's intentions using a certain strategy. It consists of a command timeliness assessment module 210, a crew intention monitoring strategy assessment module 220, and a flight control interaction module 230.

[0017] Preferably, the air-to-ground interconnection and command consistency assessment system's command timeliness judgment module evaluates the timeliness of digital control commands based on the type and urgency of the commands, combined with the aircraft's current location and the expected time to complete the command. This module considers the semantic decomposition of digital control commands and the extraction of restrictive conditions.

[0018] Preferably, the crew intent monitoring strategy determination module of the air-to-ground interconnection and command consistency analysis system determines the optimal strategy for crew intent monitoring. Crew intent extraction in flight management systems based on safety-type air-to-ground data links requires a continuous acquisition method. First, a request is sent to the designated aircraft. The onboard equipment automatically feeds back crew setting information from the flight management system to the ground. To minimize frequent uplink and downlink message interactions during crew intent extraction and avoid link congestion, this module dynamically formulates the optimal acquisition strategy, ensuring real-time extraction of crew intent while reducing message interactions. Based on the command timeliness calculated by the preceding command timeliness judgment module and combined with the crew average processing delay estimated by the human factors analysis module of the air-to-ground data interaction collaboration system, this module dynamically formulates the optimal monitoring strategy for the command and the crew, with the optimal goal of extracting crew intent as early as possible. This strategy includes monitoring trigger conditions, monitoring frequency, monitoring cycle, and monitoring termination conditions.

[0019] Preferably, the air-to-ground interconnection and command consistency assessment system's flight control interaction module realizes uplink and downlink interaction of flight control based on a safety-type air-to-ground data link; on the uplink side, it completes the on-demand delivery of digital control commands, processing of relevant feedback status, and reassembly of flight management system request messages; on the downlink side, it realizes the splitting of corresponding flight management system request messages, providing data support for the data link flight command verification and intent extraction system for crew intent extraction.

[0020] Preferably, the data link flight command verification and intent extraction system realizes the real-time collection and extraction of crew intent information and high-precision track profile information from the active route and track profile data extracted from the airborne flight management system through the safe air-to-ground data link; it consists of a high-precision track profile extraction module 310, an active route extraction module 320, a crew intent extraction module, and a command consistency judgment module 330.

[0021] Preferably, the high-precision track profile extraction module of the data link flight command verification and intent extraction system acquires FMS-WPR information from the flight management system based on a safe-class air-to-ground data link and extracts a high-precision track profile. The high-precision track profile calculation in the flight management system combines information from crew preset performance limits, flight plans, aircraft type information, load balance, and real-time atmospheric environment detected by the aircraft to perform comprehensive calculations. It fully integrates information from the airway atmospheric environment, current load, crew intent, performance limits, and optimal profile to obtain a high-precision optimal flight trajectory. The high-precision track profile includes information on the altitude, speed, and offset of subsequent points for consistency assessment of relevant commands.

[0022] Preferably, the data link flight command verification and intent extraction system activation route extraction module realizes the acquisition of FMS-FPN information from the flight management system based on the safety-class air-to-ground data link and the extraction of activation routes; the activation routes in the flight management system include flight plan, arrival and departure procedures, approach procedures, and take-off and landing runway information, and the acquisition of the above information is used for consistency judgment of relevant commands.

[0023] Preferably, the crew intent extraction module and intent consistency assessment module of the data link flight instruction verification and intent extraction system extract the crew intent based on high-precision track profiles and activated route information, and compare it with digital control instructions to assess potential conflicts. This module extracts in real time the activated routes, expected arrival times, offsets, altitude adjustments, speed adjustments, as well as arrival and departure procedures, approach procedures, and runway information set by the crew in the flight management system. When comparing crew intents, the inconsistency between the display logic of some procedures in the flight management system and the names in the ground control system should be considered, and data transcoding should be performed according to the flight management system coding specifications. The transcoded crew intents can be used to compare with the original digital control instructions issued by the control system to assess potential flight conflicts.

Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
