GENERAL
AIP831 is an Operation Keyboard for Eight-loop Simultaneous Operation for CENTUM VP’s Desktop Type HIS.
AIP831 is equipped with 8-Loop Control keys which contains touch sensors for sensing the touches. (Touch
sensors are used for “Instrument Faceplate Highlight” function of Desktop Type HIS.)
It contains an independent USB speaker (a sound function) other than buzzing alarms (buzzer sounds).

《DCS培训教材》
过程通道出现zui多的是I/O卡件故障或就地总线故障。一种原因是I/0卡件本身长时间工作,元器件老化或损坏;另外,因外部信号接地或强电信号窜人卡件也会导致通道故障。现在一般卡件本身都采取了良好的隔离措施,一般情况下不会导致故障的扩大,但此类
故障一旦出现,则直接造成过程控制或监视功能的不正常。所以要及时查明故障原因,及时进行更换卡件。
一次元件或控制设备出现故障有时不能直接被操作员发现,只有当参数异常或报警时,方引起注意。
控制处理机(过程处理机)故障一般会立即产生报警,引起操作员注意。现在控制处理机基本上全是采用1:1冗余配置,其中一台发生故障不会引起严重后果,但应立即处理故障的机器。在处理过程中,不可误动正常的处理机,否则会发生严重的后果AIP831-011
3 人为故障
在对DCS系统进行维护或故障处理时,有时会发生人为误操作现象,这对于经常进行系统维护或新参加系统检修维护的人员来说都是会发生的。一般在修改控制逻辑、下装软件、重启设备或强制设备、保护信号时zui易发生误操作事件。轻则导致部分测点、设备异常,重则造成机组或主要辅机设备停运,后果是非常严重的。在使用DCS的电厂、石化、化工厂,人为误操作发生的故障在热工专业中的不安全事件中占有很大比例。
4 电源故障
电源方面的问题也较多,如备用电源不能自投,保险配置不合理及DPU电源内部故障等造成电源中断,稳压电源波动引起保护误动及接插头接触不良导致稳压电源无输出;有的系统整个机柜通过一路保险供所有输入信号或一路电源外接负载很大,还有的控制电源既未接UPS又未有冗余备用AIP831-011
5 SOE工作不正常
SOE的结论对事故的分析、判断起了很重要的作用,但在现实中,许多电厂发生保护动作等情况时SOE未记录下来或记录时间与实际情况不符。如××电厂#1机组出现过SOE事件顺序追忆时间与实际跳闸时间不相对应,SOE时间打印浏览后不能返回,*跳闸原因在事件顺序中不能*个反映,SOE时间顺序数据不能设置等问题。而有的电厂在几次事故分析时发现SOE结论中的时序与历史曲线中的时序有偏差,有时甚至时序颠倒,具体表现于同一点在历史曲线和SOE中发生时间不*,且有时偏差很大,这会延误事故分析的进程,有时甚至误导事故分析方向。SOE问题既与系统设计不合理,SOE点没*集中在一个DPU上有关,也与系统硬件及软件设计考虑不周有关AIP831-111。
6 干扰造成的故障
干扰造成DCS故障的事例也不少。D璐系统的干扰信号可能来自于系统本身,也可能来自于外部环境。
由于不同的DCS系统对接地都有严格的规定,一旦接地电阻或接地方式达不到要求,就会使网络通信的效率降低或增加误码的可能,轻则造成部分功能不正常,重则导致网络瘫痪。
电源质量同样影响系统的稳定运行。用于DCS系统的电源既要保证电压的稳定,也要保证在一路电源故障时,无扰切换至另一路电源,否则会对系统工作产生干扰AIP831-111。
过程控制处理机主/备处理机之间的切换有时也会导致干扰。
另外,大功率的无线电通信设备如手机、对讲机等在工作时,极易造成干扰,危及系统运行。
