DCS系统在日常维护时如何能了解到系统当前故障情况?这一个问题非常的关键,只有充分的了解完毕才能更好的做出预防措施,下面浙大中控dcs卡件XP313小编来为您讲讲。
How can the DCS system know the current system failure during daily maintenance? This problem is very critical. Only after full understanding can we take better preventive measures. Now let's talk about the XP313 editor of the central control dcs card of Zhejiang University.
日常维护时注意观察很重要,重点观察了解的地方为:
It is important to observe during daily maintenance, and the key points are:
1、控制站卡件指示等显示是否异常(fail灯是否亮红灯);
1. Check whether the card indication of the control station is abnormal (whether the fail light is red);
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;
2. Enter the monitoring "fault diagnosis" screen to check whether there is card operation fault prompt and communication network exception prompt;
3、检查系统供电是否正常;
3. Check whether the system power supply is normal;
4、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)。
4. Check whether the power supply fan of the control station is running, whether the switch indicator is normal, and whether there is corrosion (whether the connector or cabinet copper bar is black, etc.).

哪些情况是控制系统问题还是工艺问题?
Which situations are control system problems or process problems?
A:出现以下情况时,说明控制系统发生问题,应立即通知微机维修人员维修,同时操作工到现场进行处理。
A: In case of the following conditions, it indicates that the control system has problems, and the microcomputer maintenance personnel shall be notified immediately for maintenance, and the operator shall go to the site to deal with them.
1、经常变化的数据长时间不变,且几个数据或所有数据都不变。
1. Frequently changing data will remain unchanged for a long time, and several or all data will remain unchanged.
2、控制分组画面中,手动自动无法切换,或手动输入数据后,一经确认,又恢复为原来的数据,修改不过来。
2. In the control grouping screen, manual and automatic cannot be switched, or the original data will be restored once confirmed after manual input of data, which cannot be modified.
3、趋势图画面中,几条趋势都为直线不变。4、监控画面中,多个数据同时波动较大。
3. In the trend graph screen, several trends are straight lines. 4. In the monitoring screen, multiple data fluctuate greatly at the same time.
判断波动数据是否为工艺上相关参数,若是相关参数则通知仪表及微机人员检查,看是否某调节系统波动引起相关参数变化,同时将相关调节系统打到手动状态,必要时到现场进行调节。
Judge whether the fluctuation data is related to the process. If it is, notify the instrument and microcomputer personnel to check whether the fluctuation of a certain regulation system causes the change of relevant parameters. At the same time, switch the relevant regulation system to the manual state, and go to the site for adjustment if necessary.
若波动数据工艺上彼此并无直接影响,则可能为微机某卡件发生故障,立即将相关自调系统打到手动调节,必要时到现场进行调节,同时,通知微机及仪表人员检查。关注我们http://www.sdjkyqyb.com,了解更多相关内容。
If the fluctuation data has no direct influence on each other in process, it may be that a card of the microcomputer has a fault. Turn the relevant automatic adjustment system to manual adjustment immediately. If necessary, go to the site for adjustment. At the same time, notify the microcomputer and instrument personnel to check. Follow us http://www.sdjkyqyb.com For more information.
