浙大中控DCS卡件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。日常维护时注意观察很重要，重点观察了解的地方为：
It is difficult to transform these DCs cards after they are put into operation, so the transformation after the problem is far better than the corresponding measures before the problem. It is important to pay attention to observation during daily maintenance. The key points to observe are:
日常维护时注意观察很重要，重点观察了解的地方为：1、控制站卡件指示等显示是否异常（fail灯是否亮红灯），2、进入监控“故障诊断”画面查看是否有卡件运行故障提示、通讯网络异常提示，
It is important to pay attention to observation during daily maintenance. The key points to be observed are: 1. Whether the card indication of the control station is abnormal (whether the fail light is red), 2. Enter the monitoring "fault diagnosis" screen to check whether there are card operation fault prompts and communication network abnormal prompts,
检查系统供电是否正常。
Check whether the system power supply is normal.
检查控制站电源风扇是否运行，交换机指示灯是否正常，是否有腐蚀现象（接线头或机柜铜条处是否发黑等现象）。
Check whether the power supply fan of the control station operates, whether the indicator light of the switch is normal, and whether there is corrosion (whether the connector or the copper bar of the cabinet is blackened, etc.).
在系统运行过程中若发现通讯故障，应重点做如下检查：
If communication failure is found during the operation of the system, the following inspections should be focused on:
1、了解清楚具体故障现象，是所有通讯中断还是某部分数据通讯异常，还是某操作站通讯异常，这对之后的排查很重要。
1. It is important to understand the specific fault phenomenon, whether it is all communication interruption, some data communication abnormality, or some operation station communication abnormality, which is very important for subsequent troubleshooting.
2、工程师权限进入监控故障诊断画面，观察是否有通讯卡件或总线故障报警（如数据转发卡，主控卡等）提示。发现卡件故障用备件更换。
2. The engineer has the authority to enter the monitoring fault diagnosis screen and observe whether there is a prompt of communication card or bus fault alarm (such as data transfer card, master card, etc.). Replace with spare parts in case of card failure.
3、检查目前网络是否通畅，检查交换机、控制站供电是否正常。可用计算机ping命令检查各网络节点是否通畅。
3. Check whether the current network is smooth, and check whether the power supply of switch and control station is normal. You can use the computer ping command to check whether each network node is unobstructed.
4、网线、交换机、SBUS线等故障均可能引起网络故障，可将其排除法更换测试。
4. Network cable, switch, SBUs cable and other faults may cause network faults, which can be eliminated and replaced for testing.
5、检查有问题操作站IP设置是否正确，卡件地址（主控卡、数据转发卡）设置是否正确、网卡驱动是否正确安装，网线连接是否不正确（交叉等）。
5. Check whether the IP setting of the problematic operation station is correct, whether the card address (master control card, data transfer card) is set correctly, whether the network card driver is installed correctly, and whether the network cable connection is incorrect (crossover, etc.).
维护事项：
Maintenance matters:
1．保持环境有一定的湿度。特别北方地区或在干燥的冬季，因静电产生故障的事例要远远大于在东南沿海地区或其他季节，所以在一些重要场所，如计算机机房、实验室、电子仪器的装调车间应考虑保持一定湿度的问题，特别是对那些封闭形的空调房间，更应有一定控制湿度的设备。
1. Keep the environment moist. Especially in northern areas or in dry winter, the failure cases caused by static electricity are far greater than those in southeast coastal areas or other seasons. Therefore, in some important places, such as computer rooms, laboratories, and electronic instrument installation and adjustment workshops, the problem of maintaining a certain humidity should be considered, especially for those closed air-conditioned rooms, there should be certain humidity control equipment.
2．铺设防静电地板，控制室和操作室均需铺设防静电地板。
2. Anti static floor shall be paved, and anti-static floor shall be paved in control room and operation room.
3．在维护插扒卡件时或用手拿捏卡件时一定注意先对手释放静电，注意尽量避免用手直接触碰卡件电子元件、面板电路和焊点。
3. When maintaining the card or holding it by hand, be sure to release static electricity by your hand first, and try to avoid touching the electronic components, panel circuits and solder joints of the card directly with your hands.
4．卡件应存放在防静电塑料盛放器或防静电塑料袋中，并存放在卡件盒中。
4. Cards should be stored in anti-static plastic containers or anti-static plastic bags, and stored in card boxes.
5．系统维护时还应注意佩带dcs防静电手腕。
5. Pay attention to wearing DCS anti-static wrist during system maintenance.
In a word, we should pay attention to preventive maintenance, that is, we should carry out proactive maintenance in a planned way to improve the stability of the system. Use each overhaul to carry out preventive maintenance on the system, so as to master the operation status of the system and clean up the hidden trouble.
