Problems solved by technology

However, since the emergency system is usually in an unattended operating state, and there are differences in the data processing methods between the emergency system and the main system, there must be differences in the current situation display between the emergency system and the main system. The inability to complete seamless "one-key" switching will bring great hidden dangers to the safety of air traffic control

Abstract

The invention discloses a method for synchronizing data between a main system and a backup system of air traffic control. By realizing the data synchronism of automatic main / backup system of the air traffic control, the problem that situation display information of the backup system is inconsistent with that of a duty system is greatly improved, thereby laying firm foundations for seamless 'one-key' switching of the main system and the backup system.

Description

technical field [0001] The invention relates to a data synchronization method, in particular to a data synchronization method between an air traffic control main system and a backup system. Background technique [0002] With the continuous and high-speed development of my country's air transport industry, the air traffic is growing rapidly, and the requirements for air traffic control service guarantee are getting higher and higher. The air traffic control automation system is one of the core systems to ensure air traffic safety. Therefore, The high reliability and high stability of the air traffic control automation system has become one of the key issues to ensure the safety of air traffic. [0003] At present, there is no ability to configure data synchronization between the actual primary and backup systems of air traffic control automation. [0004] From the perspective of practical application, a backup system without data synchronization capability cannot be called a ...
