安科瑞Acrel-3000電能管理系統(tǒng)根據(jù)包頭蘇寧廣場現(xiàn)場實(shí)際情況，整體網(wǎng)絡(luò)結(jié)構(gòu)采用在兩間商業(yè)低壓配電室內(nèi)各設(shè)置一臺(tái)內(nèi)置串口服務(wù)器的數(shù)據(jù)采集箱，每間商業(yè)低壓配電室內(nèi)的低壓進(jìn)出線儀表通過屏蔽雙絞線直接接至對應(yīng)的串口服務(wù)器然后通過網(wǎng)線接至就近的弱電井交換機(jī)上，通過包頭蘇寧廣場的內(nèi)部網(wǎng)絡(luò)將各儀表數(shù)據(jù)傳輸至一層消防控制室內(nèi)的監(jiān)控主機(jī)，保障了電能管理監(jiān)控系統(tǒng)傳輸?shù)姆€(wěn)定性與實(shí)時(shí)性。
1#商業(yè)低壓配電室內(nèi)共有11只PZ80-E4/C多功能儀表,59只PZ72-E4/C多功能儀表，儀表分為四條RS485總線接至1#商業(yè)低壓配電室數(shù)據(jù)采集箱內(nèi)串口服務(wù)器上；2#商業(yè)低壓配電室內(nèi)共有34只PZ80-E4/C多功能儀表,174只PZ72-E4/C多功能儀表，儀表分為十二條RS485總線接至2#商業(yè)低壓配電室數(shù)據(jù)采集箱內(nèi)串口服務(wù)器上。
1）站控管理層
站控管理層針對電力監(jiān)控系統(tǒng)的管理人員，是人機(jī)交互的直接窗口。在包頭蘇寧廣場工程中主要指置于一層消防控制室內(nèi)的監(jiān)控主機(jī)。
2）網(wǎng)絡(luò)通訊層
通訊層主要是由1#商業(yè)低壓配電室內(nèi)的Nport5610-8一臺(tái)、串口轉(zhuǎn)換隔離器I-7520R七只，2#商業(yè)低壓配電室內(nèi)的Nport5610-16一臺(tái)、串口轉(zhuǎn)換隔離器I-7520R十六只以及以太網(wǎng)設(shè)備及總線網(wǎng)絡(luò)組成。串口服務(wù)器主要功能是監(jiān)測現(xiàn)場智能儀表；以太網(wǎng)設(shè)備及總線網(wǎng)絡(luò)的主要功能是實(shí)現(xiàn)站控管理層于現(xiàn)場設(shè)備之間的數(shù)據(jù)交互，使配電系統(tǒng)管理集中化、信息化、智能化，極大提高了配電系統(tǒng)的安全性、可靠性和穩(wěn)定性，真正達(dá)到了無人值守的目的。
3）現(xiàn)場設(shè)備層
現(xiàn)場設(shè)備層是數(shù)據(jù)采集終端，主要由低壓智能儀表組成，智能儀表通過屏蔽雙絞線RS485接口，采用MODBUS通訊協(xié)議總線型連接接入對應(yīng)商業(yè)低壓配電室內(nèi)的串口服務(wù)器上。
系統(tǒng)結(jié)構(gòu)圖
智能儀表現(xiàn)場連接示意
現(xiàn)場儀表以手拉手方式通過屏蔽雙絞線(RVSP2*1.0)進(jìn)行通訊連接至對應(yīng)配電室數(shù)據(jù)采集箱內(nèi)的串口服務(wù)器上，每根總線連接智能儀表數(shù)量在20只左右，再經(jīng)過包頭蘇寧廣場的內(nèi)網(wǎng)將數(shù)據(jù)上傳至當(dāng)?shù)乇O(jiān)控終端。
