注意控制站全部断电的情况
由于所有控制站设备均为双路供电，一路UPS，一路市电，所以这种情况的发生几率很小。
当控制站全部断电后，监控画面上两个系统报警红灯亮，通讯中断，数据全部不刷新，所有自调系统完全失控，调节阀将恢复到初始状态，气开阀全关，气关阀全开。此时，应立即紧急处理或停车，同时到现场进行操作。
5、注意所有操作站全部断电的情况
此时，查看控制站电源指示灯是否正常，卡件诊断指示灯有无故障红灯，绿灯表示卡件正常工作，若以上都正常，则可以确定控制站工作正常，自调系统工作正常，只是操作工暂时看不到监控画面，且不能对现场进行遥控操作，立即通知微机维修人员进行维修，并到现场进行监控。
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。
2、查看操作站工作情况
当发现某个操作站死机， 监控画面数据不刷新，调节画面不起作用，查看右上方系统报警指示灯是否正常，并检查其他操作站是否工作正常，若正常，则仅该操作站有问题，通知微机维修人 员修理。若其他操作站数据也不变，则为系统通讯网络出现故障，立即通知维修人员检查网络设备的运行情况，进行修复。
3、观察操作站的断电情况
若部分操作站突然无显示，则说明UPS或市电断电，立即通知微机维修工进行维修。若有电的操作站可正常监控，此时不会影响控制系统的正常调节。
From a functional perspective, the production automation system, dynamic monitoring system, and online quality control in process industry CIMS can all be implemented by DCS. From the hierarchical structure of process industry CIMS, DCS is mainly responsible for process control and process optimization tasks, and some production scheduling and management work can also be completed on DCS.
Process Industry CIMS is a complex integrated automation system that processes all production activities of the entire enterprise. DCS, as an effective tool and implementation means, completes important basic control, real-time production data collection, dynamic monitoring and other functions in Process Industry CIMS. Compared with management computers, DCS can provide more reliable production process data, making the optimization decisions made by CIMS systems more reliable.
The production monitoring level centrally operates and manages data from the process control level, such as various optimization calculations, statistical reports, fault diagnosis, display alarms, etc. With the development of computer technology, DCS can connect with higher performance computer equipment through a network as needed to achieve more advanced centralized management functions, such as planning and scheduling, warehouse management, energy management, etc.
