【摘要】 本文针对我国电力行业市场化及信息化的需求,设计和实现了一个电能计量管理信息系统。按照管理信息系统设计和实现的基本准则,在一个实际系统中进行了实践。 针对电能计量管理业务的需求,本文分析了结构化生命周期法、企业系统规划法、原型法、关键成功因子法这几种管理信息系统的开发方法,在对这几种开发方法比较以后,提出了适合本系统开发的方法-混合原型法,并对该方法的过程和特点进行了描述。在对现行实现技术和电能计量管理系统的业务范围、操作需求进行分析和比较以后,采用了客户/服务器结构作为电能计量管理系统的业务平台。 由于电能计量管理系统涉及的数据来源复杂、类型繁多,为解决电能计量管理系统与其他业务系统和自动化设备的数据共享问题,本文分析了数据传输服务(DTS)、数据库复制、分布事务协调器(DTC)、分布式查询和数据管道等数据共享的方法,通过对几种数据传输和共享方法的深入分析,提出了针对不同类型数据源的数据共享策略,并在实际系统中进行了实现。 针对系统的安全性需求,本文采用了数据库授权控制和应用程序控制相结合的方法控制不同类型用户的数据访问权限和人机界面操作权限,这种方法对类似的客户/服务器应用设计具有一定的借鉴意义。 本文还介绍了电能计量管理系统中数据库设计的原则和方法,并设计了电能计量管理系统的数据库结构;论文还给出了部分用户界面的设计和实现方法。
【Abstract】 The electric power metering MIS is designed and implemented in this paper aimed at the competition and informational requirement in our country’s electric power industry. According to MIS’ designing and foundational rules, a practical system is finished.Combined with electric power metering requirement, this paper analyzes several following methods to develop MIS: System Development Life Cycle, Business System Planning ,Prototyping Approach and Critical Success Factors. A new Mixed Prototyping Approach to develop this system is put forward after comparing these methods. At the same time, its process and characteristic are described. After analyzing and comparing exiting technology and system’s operational process and requirement. Client/Server system is adopted as system’s operational flat.This system has many complex and multiplex data source In order to solve data sharing problem between electric power metering MIS and other systems, a lot of data sharing methods are analyzed which includes Data Transformation Service s Database Replication .. Distributed Transaction Coordinator Distributed Query and Pipeline. After deeply analyzing these methods. System’s data sharing strategy is put forward and implemented aimed at different kinds of data source.In terms of system’s security requirement, this paper adopts such a privilege controlling method as combining database control with application program to grant different operator’s asking data and operational privilege. This method has some use for reference for similar Client/Server application.The electric power metering MIS’ database designing principles and methods are introduced and system’s database is designed. In addition, user operational interface’s designing and completing methods are given in this paper.
