摘　　要：针对电能表数据采集终端数据量及访问量高导致的负载失衡问题,研究基于元模型的电能表数据采集终端负载自适应均衡方法。将电能表数据采集终端的电能表数据作为模型元数据,经数据提取、转化、加载处理后,将处理完成的数据存储至元数据仓库内。在元数据负载大小未知条件下,创新性地采用基本负载均衡算法分配元数据仓库中元数据的负载,以求解元数据的负载量。当负载过大时,通过迁移负载低节点的目录子树,均衡处理了元数据的负载量,实现了电能表数据采集终端访问负载均衡。实例测试结果表明,该方法应对速度快。该方法降低了电能表数据采集终端负载,解决了元数据请求激增问题,提高了集群负载的均衡程度。In order to face the load imbalance problem caused by the high data volume and access volume of energy meter data collection terminal,the load adaptive balancing method for energy meter data collection terminal based on metamodel is studied.The energy meter data of the energy meter data collection terminal is used as the model metadata,and after data extraction,transformation and loading processing,the processed data is stored in the metadata warehouse.Under the condition that the metadata load size is unknown,the basic load balancing algorithm is innovatively used to allocate the metadata load in the metadata warehouse,and the load volume of metadata is solved.When the load is too large,the load of metadata is balanced by migrating the catalog subtree of the node with low load,and the load balancing of access to the energy meter data collection terminal is realized.The results of the case test show that the method responds quickly.The method can reduce the load of the energy meter data collection terminal,solve the metadata request surge problem,and improve the balance of the cluster load.
