Abstract

The invention discloses a system and method for synchronizing data of main and standby systems in real time. The system comprises a parameter storage configuration unit, a data synchronization unit, a data inspection unit, a system state central control unit and a data distribution service unit. According to the invention, the synchronization of the main system database and the standby system database is realized, the bidirectional synchronization of the data between the systems is realized through the cooperative work of the units, the modules have own function, the flow is clear, a third-party open source or commercial software is not needed, and the system is independent and controllable.

Description

technical field [0001] The invention belongs to the field of civil air traffic control data communication, and in particular relates to a real-time synchronization system and method for master and backup system data. Background technique [0002] According to the safety requirements of the civil aviation industry, the core flow management system of air traffic management adopts the main / standby two system redundancy mode to operate. When one system is in the main operation mode, the other system should have the ability to take over the operation business in real time. This requires the ability to synchronize business data in real time between the primary and backup systems. [0003] The traditional information system synchronization method is to use the input of the same data source in the system data access part, such as: integrated track information, flight plan data, aviation information data, flight plan synchronization data, etc.; A synchronization protocol such as th...
