基于以太网的企业级配电网络远程监测系统

Remote monitoring system for enterprise distribution networks based on Ethernet

针对企业级配电网络监控手段单一、监控范围小、维护成本高等问题,对企业级配电网络的工作原理及配电流程、以太网总线以及RS485总线的硬件电路设计、Modbus RTU通讯协议在以太网总线和RS485总线中的应用、趋势图的设计与实现过程进行了研究,提出了一种基于以太网的企业级配电网络远程监测系统的设计方案。以Visual Studio 2008为开发环境,实现了服务器与客户端的软件设计。经现场使用及测试表明,基于以太网的企业级配电网络监测系统能够快速、稳定地进行数据传输,能够及时监测电网的信息,从而进一步保障企业设备的正常运行和人民生命财产安全。

Aiming at enterprise distribution networks＇ problems of single monitoring method, small monitoring scope and high maintenance cost and so on, some things were studied such as the working principle and process of enterprise distribution networks, the design of hardware circuits of Ethernet and RS485 bus, the application of Modbus RTU communication protocol on Ethernet and RS485 bus and the design and implementation process of trend diagram, and a design of remote monitoring system for enterprise distribution networks based on Ethcrnet was proposed. The server and client software design was achieved based on Visual Studio 2008. The test and using result indicates that this moni- toring system of enterprise distribution networks based on Ethemet can transfer date fast and steadily, monitor the information of distribution networks in time, which assures the normal operation of enterprise＇s equipments and people＇s safety of life and property.
