基于Vxworks的智能变压器在线监测系统设计与应用

为进一步提高智能变压器在线监测装置的功能集成化、结构紧凑化、网络通信标准化,满足远程管理、升级、监控等日益迫切的需求,提出基于Vxworks的智能变压器在线监测系统设计方案。通过研究VxWorks操作系统,结合Sqlite数据库、Embedthis GoAhead技术,采用B/S架构、多任务、动态优先级设计思想,依据IEC61850规约,以SQL语言、html语言、Javascript语言和矢量图形库插件为工具,实现多样化数据采集、建立嵌入式Web服务器、web浏览以及采用制造报文规范(MMS)与站控层的网络通信,实际应用结果表明,本系统运行稳定、实时性强、通信可靠快速、结构一体化等特点,具有及其广阔的推广应用前景。

Design and Application on Line Monitoring System for Intelligent Transformer Based on Vxworks

In order to improve integration, compact, communication standards of the online monitoring functions of intelligent transformer, and meet the increasingly urgent demand of remote management upgrading and monitoring in practical engineering, we put forwards a design scheme of the online monitoring system of intelligent transformer based on Vxworks. In this system, we used the SQlite database, Embedthis GoAhead technology, and the design idea of B/S architecture, multi task and dynamic priority. According to the IEC61850 protocol, we used SQL, HTML, Javascript and vector graphics library plugins as development tools. The practical results show that, the system has characteristics of stability, strong real-time, reliable and fast communication, integrated structure, and has the broad application prospect.
