一、前言

　　分散控制系统(DCS)的主要作用是对生产过程进行控制、监视、管理和决策，因此必须具有很高的可靠性，才能保证工厂的安全、经济运行。随着大规模计算机系统和计算机通信网络的不断发展，可靠性问题己经成为一个十分重要的问题，其理论也在这种形势下不断地发展和完善。可靠性技术的研究内容大致分为四个方面：可靠性设计、可靠性分析、可靠性试验、可靠性管理。

　　二、DCS系统的可靠性措施

　　在DCS系统中，采用了许多提高可靠性的技术措施。这些技术措施是建立在以下四种基本思想上的：①使系统本身不易发生故障，即所谓的故障预防;②在系统发生故障时尽可能减少故障所造成的影响，即所谓的故障保安和故障弱化;③当系统发生故障时，能够让系统继续运行，即所谓的故障容错;④当系统发生故障时，可以在不停止系统运行的情况下进行维修，即所谓的在线维修。基于这四种基本思想，DCS系统中采用了各种各样的可靠性措施降低事故的发生及所造成的损失。

　　1、严格进行质量管理和提高系统硬件水平

　　为了实现DCS系统的硬件可靠，DCS系统的制造商采取了一系列提高硬件质量的措施，如对元器件进行严格的筛选、老化元器件的降额使用、充分考虑到参数变化的影响、采用低功耗元件、采用噪声抑制技术等。

　　2、DCS系统现场设计的可靠性措施

　　DCS出现问题后，将会有无法操作、无法监视等造成设备失控的情况出现。轻者出现设备停运影响经济效益，重者危及人身和设备的安全。所以在设计中一定要根据现场的具体情况认真的考虑系统以下几点可靠性：

　　(1)电源系统

　　DCS系统的供电系统是其运行的基础，电源负荷不要超过60%，以免电源高负荷运行。同时要考虑用高品质的电源，一般笔者采用UPS电源，采用两台UPS互为备用最好，一台出现故障后备用机能够无扰切换，提高电源的可靠性。UPS输入电源不要采用电气的同一母线，要根据电气厂用接线取可靠性高的不同母线段电源，这样保证电气一段母线出现问题后不会影响DCS系统的电源。DCS电源系统(UPS、电源柜等)在现场安装时要安装在满足无尘、无振动、防腐等要求的电子设备间内，同时安装完毕通电前把电缆孔封堵，以防泄漏蒸汽从电缆孔进入电源系统造成电源短路。在DCS电源上电后，要在UPS、电源柜等设备上挂“设备带电运行禁止操作”标识牌，更不准可以在DCS电源系统上接入与DCS系统无关的负载，如检修电源、检修照明、充电设备、空调等。
