注意控制站全部斷電的情況
由于所有控制站設(shè)備均為雙路供電，一路UPS，一路市電，所以這種情況的發(fā)生幾率很小。
當控制站全部斷電后，監(jiān)控畫面上兩個系統(tǒng)報警紅燈亮，通訊中斷，數(shù)據(jù)全部不刷新，所有自調(diào)系統(tǒng)完全失控，調(diào)節(jié)閥將恢復(fù)到初始狀態(tài)，氣開閥全關(guān)，氣關(guān)閥全開。此時，應(yīng)立即緊急處理或停車，同時到現(xiàn)場進行操作。
5、注意所有操作站全部斷電的情況
此時，查看控制站電源指示燈是否正常，卡件診斷指示燈有無故障紅燈，綠燈表示卡件正常工作，若以上都正常，則可以確定控制站工作正常，自調(diào)系統(tǒng)工作正常，只是操作工暫時看不到監(jiān)控畫面，且不能對現(xiàn)場進行遙控操作，立即通知微機維修人員進行維修，并到現(xiàn)場進行監(jiān)控。
若波動數(shù)據(jù)工藝上彼此并無直接影響，則可能為微機某卡件發(fā)生故障，立即將相關(guān)自調(diào)系統(tǒng)打到手動調(diào)節(jié)，必要時到現(xiàn)場進行調(diào)節(jié)，同時，通知微機及儀表人員檢查。
2、查看操作站工作情況
當發(fā)現(xiàn)某個操作站死機， 監(jiān)控畫面數(shù)據(jù)不刷新，調(diào)節(jié)畫面不起作用，查看右上方系統(tǒng)報警指示燈是否正常，并檢查其他操作站是否工作正常，若正常，則僅該操作站有問題，通知微機維修人 員修理。若其他操作站數(shù)據(jù)也不變，則為系統(tǒng)通訊網(wǎng)絡(luò)出現(xiàn)故障，立即通知維修人員檢查網(wǎng)絡(luò)設(shè)備的運行情況，進行修復(fù)。
3、觀察操作站的斷電情況
若部分操作站突然無顯示，則說明UPS或市電斷電，立即通知微機維修工進行維修。若有電的操作站可正常監(jiān)控，此時不會影響控制系統(tǒng)的正常調(diào)節(jié)。
From a functional perspective, the production automation system, dynamic monitoring system, and online quality control in process industry CIMS can all be implemented by DCS. From the hierarchical structure of process industry CIMS, DCS is mainly responsible for process control and process optimization tasks, and some production scheduling and management work can also be completed on DCS.
Process Industry CIMS is a complex integrated automation system that processes all production activities of the entire enterprise. DCS, as an effective tool and implementation means, completes important basic control, real-time production data collection, dynamic monitoring and other functions in Process Industry CIMS. Compared with management computers, DCS can provide more reliable production process data, making the optimization decisions made by CIMS systems more reliable.
The production monitoring level centrally operates and manages data from the process control level, such as various optimization calculations, statistical reports, fault diagnosis, display alarms, etc. With the development of computer technology, DCS can connect with higher performance computer equipment through a network as needed to achieve more advanced centralized management functions, such as planning and scheduling, warehouse management, energy management, etc.
