Abstract

An information system synchronous data processing method utilizing secondary buffer technology. The method includes the steps of firstly, using uniform data format to package data in information channels, and processing frame header packaging information to realize mapping of synchronous data with corresponding information channels of the synchronous data; secondly, using multithread data synchronization method, which realizes data synchronization of high-speed multi-channel information, of a secondary buffer processing mechanism; and using and processing data after information data synchronization. The method has the advantages that the method is fine in data synchronization adaptability, better in synchronization performance, more reliable and stable, high in data synchronization precision, fine in data synchronization independence, high in reducibility, and transparent to users.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to an information system data synchronization processing method using secondary buffering technology. Background technique [0002] In an integrated information system with multiple subsystems, each subsystem has many information types and channels, and the transmission methods, processing methods and processing speeds of each system and channel information in their respective networks are different. When the information of each channel is being processed and displayed, if the channel information is related, or there are strict timing requirements for information processing timing, the integrated information system must carry out accurate information synchronization for these channel information, so as to avoid When used uniformly, the data information of different channels drifts. Especially in the integrated information system, when the channel data of some subsyst...
