浙大中控DCS卡件故障问题如何预防?要重视预防性维护,即有计划地进行主动性维护,保证系统的稳定性。下面为您讲解!
How to prevent the DCS card failure of Zhejiang University? Pay attention to preventive maintenance, that is, carry out proactive maintenance in a planned way to ensure the stability of the system. Let's explain it for you!
在DCS安装之前须重视工程设计及施工阶段的工作。如防雷电影响,接地屏蔽等,在DCS投运后对这些进行改造比较困难,因此出现问题后改造远不如出现问题之前做好相应的措施。设计上应选择合理的接地结构,如采用等电位单点接地方式;施工时应参照相关标准规范使用正确的接地连接方法。
Before DCS installation, attention must be paid to the work in the engineering design and construction stages. For example, lightning protection, grounding shielding, etc., it is difficult to reform these after DCS is put into operation, so it is far better to take corresponding measures after problems occur than before. Reasonable grounding structure shall be selected in design, such as equipotential single point grounding; The correct grounding connection method shall be used according to relevant standards and specifications during construction.
一些应用中发现的问题,应及时对现场进行改造。如电磁干扰问题,比较有效的措施是切断干扰源和DCS之间的传播途径。如控制室采用格栅型屏蔽,在信号线缆上加装滤波装置,确保信号线缆和电源线缆布线时遵循相应的标准规范,安装SPD装置防止雷电浪涌侵入等。
Some problems found in the application shall be timely reconstructed on site. For example, the effective measure is to cut off the transmission path between the interference source and DCS. If grid type shielding is used in the control room, filter devices shall be installed on the signal cables to ensure that the signal cables and power cables follow the corresponding standards and specifications, and SPD devices shall be installed to prevent lightning surge invasion.
必严格按照规范进行操作。如针对静电问题,需要严格执行插拔卡件时要戴上防静电腕带的原因;使用专用的防静电袋存放板卡等备件等。
The operation must be carried out in strict accordance with the specifications. For example, for the static problem, it is necessary to strictly implement the reason for wearing an anti-static wrist strap when inserting and removing cards; Use special anti-static bags to store spare parts such as boards and cards.
利用每次大修对系统进行预防性的维护,以掌握系统运行状态,消除故障隐患。大修期间对DCS系统应进行维护,内容包括:
Carry out preventive maintenance on the system with each overhaul to master the system operation status and eliminate potential faults. DCS system shall be maintained during overhaul, including:

(1)系统供电、接地系统检修检查。定期检查UPS电池容量和充放电时间,对接地极进行接地电阻测试。
(1) Maintenance and inspection of system power supply and grounding system. Regularly check the UPS battery capacity and charging and discharging time, and test the grounding resistance of the grounding electrode.
(2)在工艺允许前提下,定期对冗余电源、服务器、控制器、通讯网络等进行冗余测试。
(2) If the process permits, the redundant power supply, server, controller, communication network, etc. shall be tested regularly.
(3)对系统卡件进行点检。检查和整理以延长设备的寿命。
(3) Spot check the system card. Check and arrange to prolong the service life of the equipment.
(4)操作站、控制站停电检修。包括计算机内部、控制站机柜、电源箱等部件的灰尘清理。
(4) The operation station and control station are powered off for maintenance. Including dust removal of computer interior, control station cabinet, power box and other components.
(5)对电脑软硬件及系统进行维护。如磁盘整理。硬盘数据备份,软硬件测试等等。
(5) Maintain computer software, hardware and system. Such as disk defragmentation. Hard disk data backup, software and hardware testing, etc.
(6)对系统的网络通信的维护,确保可靠连接。
(6) Maintain the network communication of the system to ensure reliable connection.
(7)系统接线端子紧固,防止接线松动。检查保险端子正常。
(7) The system wiring terminals are fastened to prevent loose wiring. Check whether the fuse terminal is normal.
(8)对现场仪表设备进行检修,发现问题及时处理。
(8) Overhaul the field instruments and equipment, and deal with problems found in a timely manner.
