Flight position information playback system and playback method

Abstract

The invention discloses a flight location information playback system and a playback method. The system comprises a database, a data processing module, a playback control terminal and a playback display terminal, wherein the data processing module is independently connected with the database, the playback control terminal and the playback display terminal. The system has the following advantages that: (a) the database is adopted to store the flight location information, an index is configured for a playback condition data item, the query speed of playback speed is improved, and data playback instantaneity is realized; (b) effective information is displayed during playback initialization, only the flight information of a flight with location updating in appointed time is retained and displayed, and the flight information of the flight without locating updating in the appointed time is deleted, wherein the flight information includes the historical information of the flight; and (c) adaptive time slicing playback is carried out, a way of reading playback cache data according to a time period is adopted to greatly lower the data caching pressure of the playback control terminal, timeperiod length is adaptively regulated along with playback fast forward or slow forward, and playback fluency is guaranteed.

Description

Technical field [0001] The invention relates to a flight position information playback system and a playback method, which are used for playing back historical flight position information stored in a database. Background technique [0002] At present, there are many ways to monitor aircraft position information in the civil aviation system. The main monitoring methods in the air traffic control system include primary radar, secondary radar, and the implementation of ADS-B. Airlines mainly use ACARS POS reporting to realize flights. Real-time tracking and monitoring of location information. The flight monitoring data recording and playback system can record, save and playback the flight location information. The playback of flight location information can facilitate the relevant personnel to conduct a more intuitive analysis of the flight operation situation; at the same time, when a special situation occurs during the operation of the aircraft, the playback system can help analy...

Problems solved by technology

[0003] At present, the recording and playback of flight position information in the civil aviation system is generally implemented by traditional recorders. Since the data is stored in the hard disk in the form of files, it takes a lot of time to read the file content during playback, resulting in fast playback. The progress speed is limited, and it is not conducive to selective playback, such as only playback the location information of certain flights, or flights departing from a certain airport, etc.
