在总结早期版本软件运行经验基础上,阐述了可视化集中式绝缘在线监测系统软件的开发设计思想,重点介绍了数据库模块、图形模块、数据采集与处理模块、专家系统模块的功能实现和结构设计,并简述了帮助模块及网络浏览模块的开发:数据库可按设备分类建表;图形模块旨在实现简捷的可视化检索途径,应用文档与视图来构成模块的数据层和表示层;建立了数据采集和处理模块的公共数据接口以封装统一各种模数转换、传输方法和处理算法等;归纳了专家系统的可行性、模块组成、运行方式,将其当前任务定位于积累运行经验.软件开发采用面向对象的思想和模块化程序设计方法,界面友好,层次清晰,扩展性较好,运行较稳定.

SOFTWARE DEVELOPMENT FOR VISUALIZED CONCENTRATIVE ON-LINE INSULATION MONITORING SYSTEM

Based on the running experience from earlier version of software for visualized concentrative on-line insulation monitoring system, the approach to develop the software is expounded, the function implementation and structure design of the database module, graphic module, data acquisition and processing module and expert system module are emphatically researched. The development of help module and network browse module is briefly described as following: the importance of database is indubitable, so the data sheets can be established according to the classification of the devices; the aim of graphic module is to realize a search way which should be visualized, simple and direct; the concepts of document and view are used to describe the data layer and presentation layer of modules; in data acquisition and processing module a common data interface is established to package and uniform various D/A conversion, transmission method and processing algorithm, etc.; after the induction of the feasibility, module constituents and operating modes of expert system, it is determined that the current task of expert system is to accumulate the operation experiences. In the development of software the object-oriented and modularized programming method are applied, the developed software possesses following merits: friendly interface, clear hierarchy, good expansibility and stable operation.
