Description

Technical Field

[0001] The invention relates to the technical field of civil aviation airspace data processing, and in particular to a data link-based surface taxiway publishing device. Background Art

[0002] With the innovation and optimization of air traffic control technology in recent years, route capacity has been continuously improved, and the bottleneck restricting the growth of air traffic has shifted to airports. When large-scale flight delays, ground operations and resource allocation are limited due to special weather, route flow control or weather at other stations, how to realize ground flight taxi route planning and deliver it to relevant crews on demand has become an important means to relieve airport operation pressure and improve airport operation efficiency.

[0003] Traditional airport surface operations usually select fixed taxi routes based on the controller's experience or airport operating rules and issue them to designated flight crews via voice. However, there are shortcomings such as difficulty in dynamically considering the overall operating situation when issuing taxi instructions, limited conflict resolution solutions and untimely updates, and voice instructions are prone to human errors and omissions. Summary of the invention

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a field taxi route publishing device based on data link, which can realize the dynamic selection of digital taxi route instruction delivery strategy, and at the same time has real-time feedback on the instruction delivery status based on the data link, realizing the complete closed-loop process of message delivery-feedback-evaluation, and effectively improving the safety and efficiency of field operations.

[0005] The technical solution of the present invention is: the data link-based taxi route publishing device comprises: a signal integration analysis and inversion system, a taxi route generation system, and a data link taxi route instruction push system;

[0006] The signal integration analysis and inversion system performs scene situation information fusion and deduction, scene data link communication performance real-time analysis and evaluation functions, provides the taxi route generation system with scene operation situation and conflict domain real-time deduction, and provides on-demand push condition compliance inspection for the data link taxi route instruction push system;

[0007] The taxi route generation system generates taxi routes based on the operational situation on the ground, and also performs conflict warning and resolution.

[0008] The data link taxi route instruction push system executes real-time push and status feedback of taxi route instructions based on the safety-type ground-to-air data link, and dynamically determines the optimal data link push strategy based on the surface communication performance.

[0009] In view of the fact that traditional taxi route instructions on the ground rely on voice release, which is prone to voice frequency congestion, human errors and omissions, the present invention aims to realize real-time delivery of taxi route instructions to designated flight crews through a safety-related ground-to-air data link, which dynamically plans the taxi route based on information such as the ground operation status, operation rules and restrictions, historical track big data, and experience-based taxi routes. The crew side relies on existing airborne equipment to display the information in text form, and supports functions such as receiving status confirmation and instruction printing. At the same time, the present invention has the ability to aggregate and dynamically analyze multiple features of signals for different areas of the ground, different times, and different aircraft communication performances, fully considers the data link communication performance and aircraft communication performance to generate the instruction delivery experience time, and combines the conflict unlocking experience time, taxi route instruction warning timeliness and other factors to realize the dynamic selection of digital ground taxi route instruction delivery strategy, thereby ensuring the timeliness and accuracy of instruction push, reducing the workload of controllers and crews, and improving the safety of ground operation.
