制冷系統(tǒng)應(yīng)用PLC無線遠(yuǎn)程監(jiān)控案例
中國散裂中子源水冷和空調(diào)系統(tǒng)以及電力系統(tǒng)是用PLC控制,現(xiàn)場總共接了22臺 S7-300 PLC ,19臺觸摸屏,6臺工控機(jī),2臺廣州巨控GRM500,其中一臺GRM500通過S7-300 TCP協(xié)議采集16臺PLC數(shù)據(jù),另外一臺GRM500通過網(wǎng)口采集6臺S7-300 PLC協(xié)議,并且通過MODBUSTCP協(xié)議采集四方通訊機(jī)的電力系統(tǒng)數(shù)據(jù),同時利用GRM500自帶的邏輯功能,把電力系統(tǒng)數(shù)據(jù)寫入其中一臺S7-300PLC,系統(tǒng)通過3G無線網(wǎng)絡(luò)聯(lián)網(wǎng),實現(xiàn)做無線遠(yuǎn)程監(jiān)控和故障短信報警功能。
