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。
1、查看监控画面的数据
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。
(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。
(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。
(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。
With the improvement of automation level, DCS control system (distributed control system) has gradually replaced conventional instruments, and its advantages have been accepted by the majority of operators. However, in case of failure, it will cause plant shutdown and even accidents. How to find and deal with various faults as soon as possible is very important.
1. View the data of the monitoring screen
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 for treatment at the same time.
(1) Frequently changing data remains unchanged for a long time, and several or all data remain unchanged.
(2) In the control grouping screen, manual and automatic cannot be switched, or after manual input of data, once confirmed, it returns to the original data and cannot be modified.
(3) In the trend chart screen, several trends are straight lines and remain unchanged.
(4) In the monitoring screen, multiple data fluctuate greatly at the same time.
