DCS是現場施工的平面體現,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DCS系統的操作問題。經驗人士說,熟讀DCS操作手冊是一步,因為這些是經驗總結。下面浙大中控DCS卡件廠家為您講解有關事項。
DCS is the plane embodiment of on-site construction. It should be learned from the site, and then corresponding to the DCS operation interface. Today, I will simply talk about the operation of DCS system. Experienced people say that it is a step to read the DCS operation manual carefully, because these are experience summaries. Now, the DCS card manufacturer of Zhejiang University will explain relevant matters to you.
DCS操作規程術語含義
Meaning of terms in DCS operating procedures
注意:表示涉及的事物或操作可能引起不可預測的危險后果。
Note: It indicates that the involved things or operations may cause unpredictable dangerous consequences.
警告:表示涉及的事物或操作能引起可預見的系統運行故障。
Warning: it indicates that the involved things or operations can cause predictable system operation failures.
危險:表示涉及的事物或操作將引起系統停運,甚至設備損壞及人身傷害。
Danger: It means that the involved things or operations will cause system shutdown, even equipment damage and personal injury.
DCS操作員操作職責
DCS operator's operation responsibilities
1、監視DCS系統運行,預防可能產生的危險。
1. Monitor the operation of DCS system to prevent possible hazards.
2、隨時干預系統運行,確保安全、正常生產。
2. Intervene the system operation at any time to ensure safe and normal production.
3、系統授權運行參數的更改。
3. Change of system authorization operation parameters.

DCS系統異常情況處理
DCS system exception handling
1、DCS操作界面數據不刷新(正常情況數據每秒刷新一次),手自動切換無法操作等情況,應聯系DCS維護人員進行維護,同時立即到現場操作。
1. If the DCS operation interface data is not refreshed (the data is refreshed once a second under normal conditions), and the manual and automatic switching cannot be operated, the DCS maintenance personnel shall be contacted for maintenance, and the on-site operation shall be conducted immediately.
2、出現變送器故障,自動控制過程應立即切回手動。
2. In case of transmitter failure, the automatic control process shall be switched back to manual immediately.
3、出現閥門執行機構,回路輸出卡件等故障現象,應改為現場操作。
3. In case of valve actuator, circuit output card and other failures, on-site operation shall be changed.
4、出現DCS系統回路輸入卡件故障時應把相應控制回路切回手動,并更換故障卡件,檢查確認故障消除后方可再次投入自動。
4. In case of DCS system circuit input card fault, 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, the automatic mode can be put into operation again.
此外DCS系統出現異常斷電,應改為現場操作。重新上電后,要求工程師檢查系統情況,檢查回路參數等系統數據是否正常,確認各調節閥的開度。若有異常應重新下傳組態,一切正常后方可再次投入自動。其他異常情況請參照崗位操作規程執行。關注我們http://www.hotelfidalgo-goa.com,了解更多!
In addition, in case of abnormal power failure of DCS system, on-site operation shall be changed. After re energizing, ask the engineer to check the system condition, check whether the system data such as circuit parameters are normal, and confirm the opening of each regulating valve. If there is any abnormality, download the configuration again, and then switch to automatic mode again after everything is normal. For other exceptions, please refer to the post operation rules.
