PROBLEM TO BE SOLVED: To provide a data synchronization system allowing a plurality of route controllers to take over respective processes with each other, which has not been considered in a conventional technology.SOLUTION: A data synchronization system comprises a plurality of tracking controllers. When a first tracking controller detects abnormality of a second tracking controller, a plan data synchronization part of the first tracking controller copies plan data other than those used for the most recent control for the second tracking controller stored in an auxiliary storage of the first tracking controller to the main storage of the first tracking controller, and performs a synchronization with the plan data on the second tracking controller.SELECTED DRAWING: Figure 1
【課題】従来技術では、複数の進路制御装置の処理を互いに引き継ぐ場合は考慮されていない。【解決手段】データ同期方法は複数の追跡制御装置を備える。追跡制御装置が他の追跡制御装置の異常を検知した場合、追跡制御装置の計画データ同期部は、追跡制御装置の補助記憶装置に記憶された他の追跡制御装置の直近の制御で使用する計画データ以外の計画データを、追跡制御装置の主記憶装置にコピーして他の追跡制御装置の計画データの同期をとる。【選択図】図1
