【摘要】 近年来计算机技术、通信技术、信息技术飞速发展,电力调度数据网络的发展也十分迅速。在调度生产管理高度依赖电力调度网络和系统的同时,一旦调度数据网络中各网络设备及应用业务系统发生异常,必将严重影响调度生产的正常进行。面对这样一个要求高而且复杂的网络,采取一种有效的网络管理策略来保证电力调度数据网络高效、可靠的运行就显得尤其重要。因此,需要建设一套符合调度生产需要、高效、先进、统一的电力调度网络管理系统,利用智能手段和现代通信技术对网络和系统进行监视及异常告警。文章探讨了简单网络管理协议(SNMP)并对其管理信息库MIB和SNMP的消息结构进行了比较详细的分析,介绍了基于SNMP的网络管理模型。在深入研究了J2EE技术框架以后,提出了基于J2EE的分布式网络管理系统模型。针对某地电力调度系统的网络和业务系统的特点,提出了电力调度网络管理系统中各种网元管理的要求和网络管理性能的要求,提炼出每一个业务系统对网络管理系统的需求。针对电力调度网络管理系统的需求,设计了软件体系结构,提出了四层数据模型,并详细地探讨了数据抽象层中的信息模型,并按照业务模块功能将其划分成不同的子模块,详细地描述了各个模块的功能以及各个模块之间的关系。基于J2EE的电力调度网络管理系统具有分布式和跨平台的特性,同时还具有很强的可移植性和扩展性。更多还原

【Abstract】 Technologies on computer, communication and information have beendeveloping at a fast speed in recent years, electric power scheduling data network isalso developing rapidly. At the same time, scheduling production control is highlydepend on electric power scheduling network and system, it will has a strong impacton scheduling production normally once there are some exception of network deviceor application service system of scheduling network. Confronting the network whichhas high demand and is complex, it will be very important to adopt a effectivenetwork management policy to ensure the operation of electric power schedulingnetworkeffectivelyandreliable.Soitdemandstodevelopaelectricpowerschedulingnetwork management system which is conform to scheduling production demand andhas characters of high efficiency, advanced and uniform, this system could utilizeintelligent means and modern communication technology to monitor the network andsystemandalarmonexceptions.This paper made a study of simple network management protocol(SNMP),analyzed the management information base and message construct of SNMP indetail,introducedthenetworkmanagementmodelbasedonSNMP.Aftertheresearchof J2EE technology framework deeply, prompted a distributed network managementsystem model based on J2EE. Against the characters of an electric power schedulingsystem, prompted the demands of network element management and networkmanagement performance of electric power scheduling network management system,extracted the demands of each business system to network management. Directtowards the demands of electric power scheduling network management system,designed the software architecture, and prompted a four layer data model, and made astudyof information model for data abstract layer, and divided the system to differentsub module according to function of business module, described the function of eachmodule and the relationship of them.
