整個(gè)設(shè)施保護(hù)系統(tǒng)的工作過(guò)程是:PLC處理器通過(guò)遠(yuǎn)程I/O對(duì)生產(chǎn)設(shè)備的壓力、溫度、流量、轉(zhuǎn)速等狀態(tài)進(jìn)行判斷。一旦檢測(cè)到非正常工作情況,則立即將生產(chǎn)設(shè)備進(jìn)行全部或局部關(guān)停,同時(shí)通過(guò)人機(jī)界面向操作員報(bào)警。
除了由傳感器檢測(cè)到的非正常生產(chǎn)狀態(tài)可產(chǎn)生關(guān)停止指令以外,設(shè)施保護(hù)系統(tǒng)同時(shí)提供了手動(dòng)按鈕用以產(chǎn)生手動(dòng)關(guān)停止指令。手動(dòng)按鈕散布在生產(chǎn)區(qū)各處,由操作人員根據(jù)具體事故情況決定是否發(fā)出關(guān)停指令
