摘要
某风洞试验基地各试验外场分布在不同的物理区域,受多种条件制约,不宜采用集中式数据库,任务下达与数据上报采用手动分发与汇总,数据的时效性及完整性存在严重问题;分布式数据库可实现各场站的独立运行,但各场站与中心数据库的同步性、完整性、一致性成为最大的难题;文章根据分布式数据库的特点和风洞试验运行需求,提出了基于MSF(microsoft sync framework)框架并利用WCF(windows communication foundation)技术实现了数据自动上传下达并汇总的同步设计方案,解决了中心与下级场站之间的数据管理问题。
With its test stations scattered in different areas,Wind Tunnel Testing Base can hardly use centralized database system due to various limitations.Thus,in the course of wind tunnel testing,giving assignments and collecting data are manual,which has deeply affected the integrity and velocity of data.By using distributed database,each test station can work automatically in data exchange,but synchronization with central database still remains a big problem.According to the characteristics of a distributed database system and the requirements of wind tunnel testing,a MSF （Microsoft Sync Framework） based solution is proposed to address data management problems between headquarters and test stations,which can achieve automatic data synchronization by using WCF （Windows Communication Foundation） technology.
