Abstract

The invention relates to a target characteristic database system and a data synchronization method, which solves the problems of cumbersome data synchronization operation, low efficiency, and inability to meet the real-time data requirements of simulation or combat in previous target characteristic databases. In the network environment, the present invention can implement strategies such as storing data distribution records in the data distribution table, organizing and storing data files according to a tree structure, and establishing the same library table structure between the original library and the mirror library, so that the mirror library can apply for the original library. The data in the original database or the original database actively synchronizes the data in the mirror database in two ways. The synchronization method is flexible and efficient, and at the same time it is conducive to the protection of the target characteristic data. The data synchronization method provided by the present invention can be encapsulated into an independently called function, thereby realizing automatic calling of data.

Description

technical field [0001] The invention relates to the technical field of simulation or combat of target characteristic data, in particular to a target characteristic database system and a data synchronization method. Background technique [0002] At present, the original data of target characteristic data includes the physical, motion, optical, electromagnetic and other characteristic data, models, algorithms and templates of various types of targets obtained through measurement or simulation, so the amount of original data is very large. However, the amount of data that can be loaded in a hardware-in-the-loop simulation system or an actual system is generally small, and the access speed is required to be as fast as possible. This requires that the target characteristic data required for simulation or combat needs be extracted from the original library according to the actual application and loaded into the hardware-in-the-loop simulation system or the local mirror library of ...
