In the background of actual power - parameter measurement task , this paper adopts advanced energy chip technology and does some researches about power - parameter remote watching and control system based on lonworks field - bus technology . a power remote terminal unit ( rtu ) eu2502 is developed and realized the detecting of power - parameter based on lon network 本文正是在這種趨勢(shì)下,以一個(gè)電力參數(shù)測(cè)量實(shí)際課題為背景,采用先進(jìn)的電能計(jì)量芯片技術(shù),進(jìn)行基于lonworks現(xiàn)場(chǎng)總線(xiàn)技術(shù)的電力參數(shù)遠(yuǎn)程監(jiān)控系統(tǒng)研究,研制出電力遠(yuǎn)動(dòng)裝置( rtu , remoteterminalunit ) eu2502 ,實(shí)現(xiàn)基于lon網(wǎng)的電力參數(shù)檢測(cè)。
This paper is based on the project of " the wireless supervisory control system of street light in yantai city " , which is a typical scada system . scada systems consist of three functional components : communications equipments , remote terminal unit ( rtu ) , and control center 該系統(tǒng)是一個(gè)典型的scada系統(tǒng),路燈控制中心計(jì)算機(jī)通過(guò)vhf無(wú)線(xiàn)信道與遠(yuǎn)端現(xiàn)場(chǎng)rtu進(jìn)行通信,實(shí)現(xiàn)路燈數(shù)據(jù)的實(shí)時(shí)采集和處理,并可以自動(dòng)或手動(dòng)方式下發(fā)指令,完成對(duì)遠(yuǎn)端現(xiàn)場(chǎng)路燈的開(kāi)/關(guān)燈控制。
