2022-06-06 14:41:48 來源:http://www.dancheditu.com/ 53

DCS是現場施工的平面體現,真正要學還是應從現場學起,然后和DCS的操作界面對應起來。今天就簡單的說說中控DCS卡件系統的異常處理及注意事項。
DCS is the plane embodiment of on-site construction. We should learn from the site and then correspond to the DCS operation interface. Today, let's briefly talk about the abnormal handling and precautions of the central control DCS card system.
DCS卡件系統異常情況的處理
Handling of DCS card system abnormality
1、如果DCS操作界面數據不刷新(正常情況下每秒刷新數據),無法操作手動自動切換等,應聯系DCS維護人員進行維護,并立即前往現場進行操作。
1. If the data on the DCS operation interface is not refreshed (normally, the data is refreshed every second), and the manual and automatic switching cannot be operated, contact the DCS maintenance personnel for maintenance, and immediately go to the site for operation.
2、當變送器出現故障時,應立即將自動控制過程切換回手動。
2. When the transmitter fails, the automatic control process shall be switched back to manual immediately.
3、如有閥門執行機構、電路輸出卡等故障,應改為現場操作。
3. In case of valve actuator, circuit output card and other faults, it shall be changed to field operation.
4、當DCS系統電路輸入卡出現故障時,應將相應控制電路切換回手動,更換故障卡。檢查確認故障排除后,可再次投入自動。
4. When the DCS system circuit input card fails, the corresponding control circuit shall be switched back to manual mode and the fault card shall be replaced. After checking and confirming that the fault is eliminated, it can be put into automatic operation again.
5、DCS系統異常斷電,應改為現場運行。再次上電后,要求工程師檢查系統狀況,檢查回路參數等系統數據是否正常,確認各調節閥的開度。如果出現異常,應重新下載配置,一切正常后重新啟動自動運行。
5. The DCS system shall be changed to field operation in case of abnormal power failure. After power on again, the engineer is required to check the system condition, check whether the loop parameters and other system data are normal, and confirm the opening of each regulating valve. In case of any exception, download the configuration again, and restart the automatic operation after everything is normal.
6、其他異常情況請參考后期操作流程。
6. For other abnormal conditions, please refer to the later operation process.
DCS卡件系統注意事項:
Precautions for DCS card system:
當系統出現電源故障時,應立即將系統投入自動控制的回路切換為手動。在供電正常的情況下,檢查系統是否運行,系統數據是否正常。如有異常,重新下載配置,檢查系統參數。一切正常后,再次進入自動即可。(參數表參考相關資料)
In case of power failure of the system, the loop that the system is put into automatic control shall be switched to manual immediately. When the power supply is normal, check whether the system operates and whether the system data is normal. In case of any abnormality, download the configuration again and check the system parameters. After everything is normal, you can enter the automatic mode again. (refer to relevant data for parameter table)

系統啟動和上電順序:UPS、控制站、顯示器、操作站計算機。
System startup and power on sequence: UPS, control station, display, operation station computer.
關機順序:控制站電腦、顯示器、控制站、UPS。
Shutdown sequence: control station computer, display, control station and UPS.
操作員密碼維護:每個操作員站的操作員密碼之間沒有關系,必須單獨建立。密碼是保證系統安全正常運行的前提,必須嚴格執行。
Operator password maintenance: there is no relationship between operator passwords of each operator station, which must be established separately. Password is the premise to ensure the safe and normal operation of the system and must be strictly implemented.
歷史數據保存在操作站的硬盤上,與系統斷電等因素無關。歷史數據是追溯事故責任的重要手段。
The historical data is stored on the hard disk of the operation station, which has nothing to do with the system power failure and other factors. Historical data is an important means to trace accident liability.
操作員站計算機是系統的重要組成部分,必須保持功能和清潔。
The operator station computer is an important part of the system and must be kept functional and clean.
浙大中控DCS卡件出現故障時,應立即將相應控制回路切換回手動,并通知DCS系統維護人員立即更換故障卡。檢查確認故障排除后,系統可再次進入自動模式。
When the DCS card of Zheda central control system fails, the corresponding control circuit shall be switched back to manual immediately, and the DCS system maintenance personnel shall be notified to replace the failed card immediately. After checking and confirming that the fault is eliminated, the system can enter the automatic mode again.
