浙大中控DCS系统运行的管理,是指DCS系统,常用是JX-0300XP运行中控制系统巡检(一般一天检查一次),热控设备运停(设备检修时),设备完好情况(PDCA管理体制运作),异常分析、处理情况等内容的管理。
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系统运行管理应在执行以往常规热控设备管理及热控备件管理等。要根据浙大中控DCS系统特性制定对应的运行维护方法。如对控制站的数据库,定期检查和导出备份,以便于事故的分析;对其硬盘要定期检查,以防满盘,造成新的数据存不进去。
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.

操作站停电时一定要先执行停机程序后再停电;严禁随意停、送电操作,系统必须保证UPS电源稳定可靠。要加强数据网线接头的保护,以防断线。另外,DCS控制信号线缆,要注意与高压电缆分开;将电缆穿保护套管,以防受到干扰。DCS备件的存放应用原厂配件,定期对备件进行检查一般有XP313/XP314/XP316/XP322/XP362/XP363等。DCS装置发生故障,需用备件更换时,使用前必须对备件进行功能测试,以免造成系统大面积短路,影响整个系统的运行。
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.
加强软件PRO的管理,化工厂、电厂对DCS硬件维修管理较重视,特别是中控系统卡件都是经过了防腐处理,硬件安全性很高,但对软件管理办法不完善。如现场任何人都可修改组态,软件不能及时复制、备份并统一管理,这对运行中的系统非常危险。因此软、硬件要同时进行管理,规范DCS系统软件和应用软件管理,软件的修改、更新、升级必须履行审批授权及负责人制度。
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、升级软件前,应对软件进行备份;系统组态程序在修改完逻辑后要进行备份一次。对操作员站专用键盘2118m,要严格规定其使用权限,以免造成误操作。各工作站的软件版本一定要检查清楚,各站务必要保持一致。未经测试确认的各种软件严禁下载到已运行的DCS系统中使用,必须建立有针对性的DCS系统防病毒措施,操作站上的光驱,USB接口盖章卡封,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.
