随着自动化水平的提高，dcs控制系统(集散控制系统)逐渐代替了常规仪表，其优越性已被广大操作人员所接受。但发生故障时，会造成装置停车甚至事故，各种故障如何及早发现及恰当处理就显得非常重要。

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。如水溶液全循环装置中，尿素合成塔压力正常时为l9.67MPa，如果突然大范围波动，此时势必引起下游的中压系统、低压系统压力波动，这种情况是由于几个相关参数中某一参数波动引起其他参数变化，并不是控制系统本身故障。

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。

With the improvement of automation level, dcs control system (distributed control system) has gradually replaced conventional instruments, and its superiority has been accepted by the majority of operators. However, when the fault occurs, it will cause the device to stop and even accidents, so how to find and deal with various faults as early as possible is very important.

Determine whether the fluctuation data is related to the process parameters, if it is relevant parameters, notify the instrument and computer personnel to check whether the fluctuation of a regulation system causes the change of relevant parameters, and at the same time, the relevant regulation system is hit to the manual state, and if necessary, go to the site for adjustment. For example, in the aqueous solution full cycle device, the normal pressure of the urea converter is l9.67MPa, if the sudden wide range of fluctuations, this time is bound to cause the downstream of the medium pressure system, low pressure system pressure fluctuations, this situation is due to the fluctuation of several related parameters caused by a parameter changes in other parameters, not the control system itself fault.

If the fluctuation data process does not directly affect each other, it may be a microcomputer card failure, immediately the relevant self-adjusting system to manual adjustment, if necessary to the scene for adjustment, at the same time, notify the microcomputer and instrument personnel to check.
