  說到DCS的操作,不少化工人都想知道應該從哪兒學起?實踐應用中應該留意哪些問題?其實,DCS是現場施工的平麵表現,真正要學還是應從現場學起,然後和DCS的操作界麵對應起來。首先要有紮實的理論根底學問,然後才幹分離DCS的操作計劃來很好地調整或控製現場。下麵浙大中控DCS卡件的小編來給大家介紹一下。
  When it comes to DCS operation, many chemical workers want to know where to learn from? What problems should be paid attention to in practice? In fact, DCS is the plane performance of on-site construction. It should be learned from the site, and then correspond to the operation interface of DCS. First of all, we should have a solid theoretical foundation knowledge, and then we can separate the DCS operation plan to adjust or control the site well. Next, we will introduce the DCS card of Zhejiang University.
  比如:理解反應時,針對不同的反應,理解溫度、壓力、流量、組分含量、分布等對反應的影響,多個控製手段,分清主次,弄清各個參數對反應影響的大小,如何調到優等。
  For example, when understanding the reaction, we should understand the influence of temperature, pressure, flow rate, component content and distribution on the reaction according to different reactions. We should distinguish the primary and secondary control methods, clarify the influence of each parameter on the reaction, and how to adjust it to the superior level.
  經驗人士說,熟讀DCS操作手冊是初步,因為這些是經驗總結,而後根據實際操作慢慢理解消化。
  Experienced people said that it is preliminary to read DCS operation manual, because these are experience summary, and then slowly understand and digest according to actual operation.
  總體說明
  General description
  係統的所有操作均在Advantrol軟件下實現。
  All operations of the system are implemented under AdvanTrol software.
  本規程提及的術語
  Terms mentioned in this procedure
  1)注意:表示涉及的事物或操作可能引起不可預測的危險後果。
  1) Note: indicates that the object or operation involved may cause unpredictable dangerous consequences.
  2) 警告:表示涉及的事物或操作能引起可預見的係統運行故障。
  2) Warning: indicates that the object or operation involved can cause foreseeable system operation failure.
  3)危險:表示涉及的事物或操作將引起係統停運,甚至設備損壞及人身傷害。
  3) Danger: it means that the object or operation involved will cause system shutdown, even equipment damage and personal injury.
  操作員操作職責
  Operator operation responsibility
  1)監視DCS係統運行,預防可能產生的危險。
  1) Monitor the operation of DCS system to prevent possible hazards.
  2)隨時幹預係統運行,確保安全、正常生產。
  2) Intervene system operation at any time to ensure safe and normal production.
  3)係統授權運行參數的更改。
  3) Change of system authorized operation parameters.

  係統異常情況處理
  System exception handling
  1)DCS操作界麵數據不刷新(正常情況數據每秒刷新一次),手自動切換無法操作等情況,應聯係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 per second under normal conditions), and the manual and automatic switching cannot be operated, the DCS maintenance personnel shall be contacted for maintenance, and the field operation shall be carried out immediately.
  2)出現變送器故障,自動控製過程應立即切回手動。
  2) In case of transmitter failure, the automatic control process should 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 fault phenomena, it should be changed to field operation.
  4)出現DCS係統回路輸入卡件故障時應把相應控製回路切回手動,並更換故障卡件,檢查確認故障 消除後方可再次投入自動。
  4) In case of DCS system circuit input card failure, the corresponding control circuit should be switched back to manual mode, and the fault card should be replaced. After the fault is eliminated, it can be put into automatic operation again.
  5)DCS係統出現異常斷電,應改為現場操作。重新上電後,要求工程師檢查係統情況,檢查回路參 數等係統數據是否正常,確認各調節閥的開度。若有異常應重新下傳組態,一切正常後方可再次投入自動。
  5) In case of abnormal power failure of DCS system, it should be changed to field operation. After power on again, the engineer is required to check the system condition, check whether the system data such as circuit parameters are normal, and confirm the opening of each control valve. In case of any abnormality, it is necessary to download the configuration again. After everything is normal, it can be put into automatic mode again.
  6)其他異常情況請參照崗位操作規程執行。
  6) For other abnormal conditions, please refer to the post operation procedures.
  報警處理
  Alarm processing
  工藝指標產生報警時會有聲音提示,報警信息在報警信息欄和報警一覽畫麵中指示,報警情況了解後,用消音按鈕關閉當前的報警聲音,分析報警原因後采取相應的操作。
  When the process indicators give an alarm, there will be a sound prompt, and the alarm information will be indicated in the alarm information column and alarm list screen. After understanding the alarm situation, use the mute button to turn off the current alarm sound, and take corresponding actions after analyzing the cause of the alarm.
  檢測控製點
  Detection control point
  隨時密切監視與控製息息相關溫度、壓力、液位、電流、閥位等。
  Closely monitor and control temperature, pressure, liquid level, current, valve position, etc.
