1、基于GSM短消息的路燈遠程監(jiān)控系統(tǒng)設計摘要本文從解決傳統(tǒng)路燈控制方式不靈活、管理維護困難的實際問題出發(fā),深入了解了各種通訊方式在遠程測控領域中的應用情況,設計出了~種通用的基于GSM網(wǎng)絡的遠程監(jiān)控與數(shù)據(jù)采集(SCADA)系統(tǒng)。系統(tǒng)采用GSM網(wǎng)絡作為數(shù)據(jù)傳輸?shù)钠脚_,具有網(wǎng)絡覆蓋面廣、系統(tǒng)運行可靠、抗干擾能力強、用戶投資小、運營費用少等優(yōu)點。文中給出了系統(tǒng)實現(xiàn)方案、監(jiān)控中心和遠程測控終端的軟硬件架構,并對短消息業(yè)務中涉及的相關技術如發(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
