1、基于GSM短消息的路燈遠(yuǎn)程監(jiān)控系統(tǒng)設(shè)計摘要本文從解決傳統(tǒng)路燈控制方式不靈活、管理維護(hù)困難的實際問題出發(fā),深入了解了各種通訊方式在遠(yuǎn)程測控領(lǐng)域中的應(yīng)用情況,設(shè)計出了~種通用的基于GSM網(wǎng)絡(luò)的遠(yuǎn)程監(jiān)控與數(shù)據(jù)采集(SCADA)系統(tǒng)。系統(tǒng)采用GSM網(wǎng)絡(luò)作為數(shù)據(jù)傳輸?shù)钠脚_,具有網(wǎng)絡(luò)覆蓋面廣、系統(tǒng)運(yùn)行可靠、抗干擾能力強(qiáng)、用戶投資小、運(yùn)營費(fèi)用少等優(yōu)點(diǎn)。文中給出了系統(tǒng)實現(xiàn)方案、監(jiān)控中心和遠(yuǎn)程測控終端的軟硬件架構(gòu),并對短消息業(yè)務(wù)中涉及的相關(guān)技術(shù)如發(fā)送模式、PDU數(shù)據(jù)串格式等做了深入剖析。在解決路燈遠(yuǎn)程監(jiān)控的問題上,考慮到傳輸?shù)臄?shù)據(jù)量較小且對實時性要求
