摘要
针对用电采集系统中的数据补采提出了一种基于缓存的智能用电海量数据补采策略,通过预先在分布式缓存中按采集任务对需要采集的数据项进行初始化,采用数据包标记法提取元信息数据后通过哈希算法进行精确定位和快速标记,补采服务检索缓存中的标记信息生成相应的补采任务,该方法提高了智能用电采集系统的补采效率,有效提升了系统的采集成功率。
This paper proposes a distributed cache based data supplement acquisition strategy for massive data mining complement in electricity acquisition system. By pre-initializing required data items in the distributed cache, using hash algorithm to precisely locate the meta data extracted by data package mark method and generating the supplementary acquisition task with the tag information pre-stored in distributed cache, the complement trick efficiency of smart electricity acquisition system and the system acquisition success rate is significantly improved.
