摘　　要：由于当前电力系统移动作业计划性强,户外作业网络不可靠,业务数据量大,并发度高等特点,传统数据同步技术及冲突处理方式,已难以满足用户的高可用性需求。提出了一种基于数据包的移动数据同步冲突预处理与消解策略,通过定义数据包规则进行冲突检测,以中间数据库为媒介进行冲突消解,保证了移动终端与业务系统之间的数据的一致性,并解决了国内外同类方案未能解决的业务高峰期大数据量、高并发引起的业务系统性能瓶颈问题,表现出良好的快速响应能力和稳定性。Nowadays,because of the current power system of mobile operation high planning,outdoor operation network is not reliable,large amount of business data,high concurrency,traditional data synchronization technology and conflict resolution mode,is difficult to meet the user＇s demand for high availability.This paper proposes a conflict preprocessing and digestion-resolution of mobile data synchronization based on data package,conflict detection by the packet rule,and conflict resolution in the middle database,to ensure the consistency between the mobile terminal and business system data,and solves the bottleneck problem of business system the peak of the business of large amount of data,the domestic and foreign similar schemes fail to resolve the cause of high concurrency.The experiment showed good stability and fast response ability.
