Description

Route transmission and processing method between flight information systems

technical field

The invention belongs to the technical field of military air traffic control automation, and in particular relates to a route transmission and processing method between flight information systems.

Background technique

Flight information is one of the important information sources for all air traffic control work. It is a general term for various types of information used by military and civil aviation flight control personnel to coordinate, master flight plans and report the implementation of the plan. Civil aviation calls it the civil aviation flight dynamic report. Corresponds to the "Dynamic and Regulatory Telegram" in the ICAO "Air Traffic Services Telegram".

The flight information system is a system for editing, transmitting and processing flight information. The first step after the receipt of flight information is to identify the text elements of the message. The main elements of flight information generally include: time, aircraft type, secondary code, take-off and landing airports, routes and other elements. Due to the different nature of missions, military and civil aviation flights also include their own special elements. Among them, the analysis of route elements has certain difficulties. During the parsing process, it is necessary to extract the route/route point from the route one by one (if it is a military aviation plan, it may contain training airspace information), and search for the route point in the basic data stored in the system according to the route/route code. The geographic information, complete the analysis. In the parsing process, failures are often encountered, and the receiver cannot parse the route/route code transmitted by the other party. This is due to the difference in the basic data stored in the systems of the receiver and the receiver. Sometimes, it also occurs that the same placemark name stored by both parties has different latitude and longitude information, and an erroneous parsing result occurs. Compared with unusable false positives, ambiguous reports are more serious and may cause flight information receivers to conduct mission management with erroneous information.

The military air management system and the civil air management system are currently carried out in accordance with the method of "separate planning, separate construction, and self-contained systems", and the basic data of the two sides have not been unified. Not only between military aviation and civil aviation systems, but also multiple control center systems of military aviation have different basic data due to different construction periods. Although military aviation and civil aviation have done the unification of basic data, due to the constant changes of basic data, there are differences in basic data between the military and civil aviation flight information systems, resulting in the inability of many normal flight information to be communicated between control centers. .
