中控DCS卡件系统的异常处理及注意事项

2022-06-06 14:41:48 来源:http://www.sdjkyqyb.com/ 53

DCS是现场施工的平面体现,真正要学还是应从现场学起,然后和DCS的操作界面对应起来。今天就简单的说说中控DCS卡件系统的异常处理及注意事项。
DCS is the plane embodiment of on-site construction. We should learn from the site and then correspond to the DCS operation interface. Today, let's briefly talk about the abnormal handling and precautions of the central control DCS card system.
DCS卡件系统异常情况的处理
Handling of DCS card system abnormality
1、如果DCS操作界面数据不刷新(正常情况下每秒刷新数据),无法操作手动自动切换等,应联系DCS维护人员进行维护,并立即前往现场进行操作。
1. If the data on the DCS operation interface is not refreshed (normally, the data is refreshed every second), and the manual and automatic switching cannot be operated, contact the DCS maintenance personnel for maintenance, and immediately go to the site for operation.
2、当变送器出现故障时,应立即将自动控制过程切换回手动。
2. When the transmitter fails, the automatic control process shall be switched back to manual immediately.
3、如有阀门执行机构、电路输出卡等故障,应改为现场操作。
3. In case of valve actuator, circuit output card and other faults, it shall be changed to field operation.
4、当DCS系统电路输入卡出现故障时,应将相应控制电路切换回手动,更换故障卡。检查确认故障排除后,可再次投入自动。
4. When the DCS system circuit input card fails, the corresponding control circuit shall be switched back to manual mode and the fault card shall be replaced. After checking and confirming that the fault is eliminated, it can be put into automatic operation again.
5、DCS系统异常断电,应改为现场运行。再次上电后,要求工程师检查系统状况,检查回路参数等系统数据是否正常,确认各调节阀的开度。如果出现异常,应重新下载配置,一切正常后重新启动自动运行。
5. The DCS system shall be changed to field operation in case of abnormal power failure. After power on again, the engineer is required to check the system condition, check whether the loop parameters and other system data are normal, and confirm the opening of each regulating valve. In case of any exception, download the configuration again, and restart the automatic operation after everything is normal.
6、其他异常情况请参考后期操作流程。
6. For other abnormal conditions, please refer to the later operation process.
DCS卡件系统注意事项:
Precautions for DCS card system:
当系统出现电源故障时,应立即将系统投入自动控制的回路切换为手动。在供电正常的情况下,检查系统是否运行,系统数据是否正常。如有异常,重新下载配置,检查系统参数。一切正常后,再次进入自动即可。(参数表参考相关资料)
In case of power failure of the system, the loop that the system is put into automatic control shall be switched to manual immediately. When the power supply is normal, check whether the system operates and whether the system data is normal. In case of any abnormality, download the configuration again and check the system parameters. After everything is normal, you can enter the automatic mode again. (refer to relevant data for parameter table)

系统启动和上电顺序:UPS、控制站、显示器、操作站计算机。
System startup and power on sequence: UPS, control station, display, operation station computer.
关机顺序:控制站电脑、显示器、控制站、UPS。
Shutdown sequence: control station computer, display, control station and UPS.
操作员密码维护:每个操作员站的操作员密码之间没有关系,必须单独建立。密码是保证系统安全正常运行的前提,必须严格执行。
Operator password maintenance: there is no relationship between operator passwords of each operator station, which must be established separately. Password is the premise to ensure the safe and normal operation of the system and must be strictly implemented.
历史数据保存在操作站的硬盘上,与系统断电等因素无关。历史数据是追溯事故责任的重要手段。
The historical data is stored on the hard disk of the operation station, which has nothing to do with the system power failure and other factors. Historical data is an important means to trace accident liability.
操作员站计算机是系统的重要组成部分,必须保持功能和清洁。
The operator station computer is an important part of the system and must be kept functional and clean.
浙大中控DCS卡件出现故障时,应立即将相应控制回路切换回手动,并通知DCS系统维护人员立即更换故障卡。检查确认故障排除后,系统可再次进入自动模式。
When the DCS card of Zheda central control system fails, the corresponding control circuit shall be switched back to manual immediately, and the DCS system maintenance personnel shall be notified to replace the failed card immediately. After checking and confirming that the fault is eliminated, the system can enter the automatic mode again.
