地县一体化调度自动化系统中的数据缓存和同步方法

为了使地县一体化调度自动化系统出现解列运行后全系统重要数据不丢失,提出了一种地县一体化调度自动化系统解并列状态下的数据缓存和同步方法。该方法采用缓存文件和缓存实时库2种方式对一体化系统出现解列运行后针对解列侧系统进行数据缓存,并在解列侧系统恢复一体化运行后利用缓存的数据进行全系统数据同步。该方法已应用于南通地县一体化调...

Data Cache and Synchronization Method in Prefecture-county Integrated Dispatching Automation System

In order to solve the problem with the prefecture-county integrated dispatching automation system of how to keep the whole system running without losing important data in the splitting operation state,a method is proposed for system solution of data cache and synchronization on the parallel and splitting operation side of the prefecture-county integrated dispatching automation system.With this method,two ways are adopted for the splitting side after splitting operation of the integrated system,that is,local file cache and cache in the local real-time database system.In addition,following the recovery of integrated operation on the splitting side,synchronization of the whole system is carried out using the metadata cache.This method is applied in the Nantong prefecture-county integrated dispatching system.
