【摘要】 本文介绍了一个基于LonWorks技术的变电站远程调度监控系统。该系统分成监测控制级,网络数据传输级,远程调度监控中心实时数据集成级三层体系结构,主要在监测控制级设计了一个嵌入式LonWorks网关对底层的Lontalk协议的数据包和高层的Modbus协议的RTU数据包相互转换,再通过modem和电力专用通信网,实现了变电站的远程调度监控功能。更多还原

【Abstract】 This article introduces the transformer substation remote dispatching monitor & control system based LonWorks technology.This system comprised three layer structure:monitor&control layer, network data transportation layer,and the realtime data integration layer of the remote monitor centre. Primarily a embedded LonWorks gateway is designed to transform data packet between the bottom-layered Lontalk data packet and the upper-layered RTU data packet of Modbus protocol in the monitor & control layer, and via Modem and power private communication network, the transformer substation remote monitor system is realized.更多还原
