针对目前分布式异构海量电能质量监测数据不能有效管理的问题,提出一种基于Web服务及Agent的管理系统。首先利用Web服务实现各分布式异构数据的管理,其次引入本体技术对Web服务进行语义拓展,使系统可以实现知识层面的智能查询,同时使各Web服务能被Agent调用,通过Web服务及Agent技术的结合实现对各系统子功能的封装;Agent利用自身主动性和感知外部环境的能力,分析需求、协调任务,形成Agent动态联盟完成各任务,从而实现对电能质量基本指标和事件数据自主管理和智能查询的目的。实例研究表明,系统有效地解决了电能质量监测中异构海量数据统一查询、管理问题,并具有高效、准确和智能性。
Aiming at the problem that distributed heterogeneous mass power quality monitoring data can not be effectively managed, a management system based on Web service and Agent is proposed. Firstly, Web services are used to realize the management of distributed heterogeneous data. Secondly, ontology is introduced to semantic expansion of Web services so that the system can intelligently query at the knowledge level. At the same time, each Web service can be called by Agent. Through Web services and Agent Technology to realize the encapsulation of sub-functions of each system. Agent takes advantage of its own initiative and the ability to perceive the external environment to analyze needs and coordinate tasks to form Agent dynamic alliance to accomplish various tasks, so as to achieve autonomous management of basic indicators and event data of power quality And intelligent query purposes. The case study shows that the system effectively solves the problem of uniform query and management of heterogeneous massive data in power quality monitoring, and is efficient, accurate and intelligent.
