描述
該方案已在沈陽皇姑熱電有限公司供暖監(jiān)控系統(tǒng)中得到良好實(shí)際應(yīng)用,下面做一詳細(xì)說明。
2系統(tǒng)概述
沈陽皇姑熱電有限公司供暖監(jiān)控系統(tǒng)如圖1所示由三部分組成:現(xiàn)場換熱站HOLLiAS-PLCG5控制部分、GPRS數(shù)據(jù)傳輸部分、調(diào)度室數(shù)據(jù)中心。通過HOLLiAS-PLCG5CP240RS-232模塊完成與GPRSDTU的數(shù)據(jù)交互。PLC定時(shí)將數(shù)據(jù)發(fā)送給GPRSDTU,同時(shí)PLC實(shí)時(shí)接收DTU發(fā)來的數(shù)據(jù)完成相應(yīng)控制功能。GPRSDTU在收到PLC發(fā)來的數(shù)據(jù)會(huì)立即轉(zhuǎn)發(fā)到數(shù)據(jù)中心。根據(jù)換熱站的實(shí)際情況,此次換熱站PLC每次向DTU發(fā)送幀格式數(shù)據(jù)量為140字節(jié),包括所有模擬量和開關(guān)量。
(1)現(xiàn)場換熱站HOLLiAS-PLCG5將各工藝參數(shù)實(shí)時(shí)采集后通過RS-232串口通信模塊將數(shù)據(jù)送往GPRSDTU通信模塊;同時(shí),還可通過該通信模塊接收調(diào)度中心的指令。
(2)GPRS數(shù)據(jù)傳輸部分在對(duì)GPRSDTU通信模塊進(jìn)行配置時(shí)預(yù)先輸入數(shù)據(jù)中心的固定IP地址。GPRSDTU通信模塊收到HOLLiAS-PLCG5發(fā)來的數(shù)據(jù)后,把這些數(shù)據(jù)送到前面設(shè)置的IP地址主機(jī)中(即數(shù)據(jù)中心路由器)。GPRSDTU發(fā)送數(shù)據(jù)的過程為:數(shù)據(jù)送到中國移動(dòng)GPRS網(wǎng)絡(luò)中,然后再經(jīng)過Internet,最后在數(shù)據(jù)中心通過ADSL進(jìn)行接收,數(shù)據(jù)中心路由器收到各換熱站的數(shù)據(jù)后轉(zhuǎn)發(fā)到數(shù)據(jù)服務(wù)器上。
(3)調(diào)度室數(shù)據(jù)中心由ADSLMODEM、防火墻、路由器、數(shù)據(jù)中心服務(wù)器、客戶機(jī)、網(wǎng)關(guān)機(jī)組成。數(shù)據(jù)中心服務(wù)器通過ADSLModem接收來自各換熱站的數(shù)據(jù),并對(duì)數(shù)據(jù)進(jìn)行存儲(chǔ)、歷史趨勢(shì)分析、報(bào)表打印等,其中一部分?jǐn)?shù)據(jù)還傳送到全廠MIS系統(tǒng)。
