              浙大中控DCS系統運行維護步驟!

              2021-09-17 16:42:12 來源:http://www.eboudy.com/ 53

              浙大中控DCS系統運行的管理,是指DCS系統,常用是JX-0300XP運行中控制系統巡檢(一般一天檢查一次),熱控設備運停(設備檢修時),設備完好情況(PDCA管理體制運作),異常分析、處理情況等內容的管理。
              The operation management of central control DCS system of Zhejiang University refers to the DCS system, which is commonly used for the management of jx-0300xp operation control system Patrol Inspection (generally once a day), thermal control equipment operation and shutdown (during equipment maintenance), equipment integrity (PDCA management system operation), anomaly analysis, handling, etc.
              浙大中控DCS系統運行管理應在執行以往常規熱控設備管理及熱控備件管理等。要根據浙大中控DCS系統特性制定對應的運行維護方法。如對控制站的數據庫,定期檢查和導出備份,以便于事故的分析;對其硬盤要定期檢查,以防滿盤,造成新的數據存不進去。
              The operation management of central control DCS system of Zhejiang University shall be based on the previous conventional thermal control equipment management and thermal control spare parts management. Corresponding operation and maintenance methods shall be formulated according to the characteristics of central control DCS system of Zhejiang University. For example, the database of the control station shall be regularly checked and exported for backup, so as to facilitate accident analysis; The hard disk should be checked regularly to prevent the disk from being full, resulting in new data not being stored.

              操作站停電時一定要先執行停機程序后再停電;嚴禁隨意停、送電操作,系統必須保證UPS電源穩定可靠。要加強數據網線接頭的保護,以防斷線。另外,DCS控制信號線纜,要注意與高壓電纜分開;將電纜穿保護套管,以防受到干擾。DCS備件的存放應用原廠配件,定期對備件進行檢查一般有XP313/XP314/XP316/XP322/XP362/XP363等。DCS裝置發生故障,需用備件更換時,使用前必須對備件進行功能測試,以免造成系統大面積短路,影響整個系統的運行。
              In case of power failure in the operation station, the shutdown procedure must be executed before power failure; It is strictly prohibited to stop and send power at will. The system must ensure the stability and reliability of UPS power supply. Strengthen the protection of data network cable connector to prevent disconnection. In addition, the DCS control signal cable shall be separated from the high-voltage cable; Put the cable through the protective sleeve to prevent interference. DCS spare parts shall be stored with original accessories, and the spare parts shall be inspected regularly, generally including xp313 / xp314 / xp316 / xp322 / xp362 / xp363, etc. When the DCS device fails and needs to be replaced with spare parts, the spare parts must be tested before use, so as not to cause a large-area short circuit of the system and affect the operation of the whole system.
              加強軟件PRO的管理,化工廠、電廠對DCS硬件維修管理較重視,特別是中控系統卡件都是經過了防腐處理,硬件安全性很高,但對軟件管理辦法不完善。如現場任何人都可修改組態,軟件不能及時復制、備份并統一管理,這對運行中的系統非常危險。因此軟、硬件要同時進行管理,規范DCS系統軟件和應用軟件管理,軟件的修改、更新、升級必須履行審批授權及負責人制度。
              Strengthen the management of software Pro. Chemical plants and power plants pay more attention to DCS hardware maintenance management, especially the cards of central control system have been subject to anti-corrosion treatment, and the hardware safety is very high, but the software management methods are not perfect. If anyone on site can modify the configuration, the software cannot be copied, backed up and managed in a unified manner, which is very dangerous to the running system. Therefore, the software and hardware shall be managed at the same time to standardize the management of DCS system software and application software. The modification, update and upgrading of software must comply with the approval authorization and person in charge system.
              在修改、更新、升級軟件前,應對軟件進行備份;系統組態程序在修改完邏輯后要進行備份一次。對操作員站專用鍵盤2118m,要嚴格規定其使用權限,以免造成誤操作。各工作站的軟件版本一定要檢查清楚,各站務必要保持一致。未經測試確認的各種軟件嚴禁下載到已運行的DCS系統中使用,必須建立有針對性的DCS系統防病毒措施,操作站上的光驅,USB接口蓋章卡封,防止外部病毒侵入。
              Before modifying, updating and upgrading the software, the software shall be backed up; The system configuration program shall be backed up once after modifying the logic. For the 2118m special keyboard of the operator station, its use authority shall be strictly stipulated to avoid misoperation. The software version of each workstation must be checked clearly, and each station must be consistent. All kinds of software that has not been tested and confirmed shall not be downloaded to the running DCS system for use. Targeted DCS system anti-virus measures must be established. The optical drive and USB interface on the operation station shall be sealed to prevent external virus intrusion.
