有了成绩要马上忘掉，这样才不会自寻烦恼；有了错误要时刻记住，这样才不会重蹈覆辙；有了机遇要马上抓住，这样才不会失去机会；有了困难要寻找对策，这样才能迎刃而解。

在原来控制系统基础上增加一套PLC双机热备系统，使除灰控制系统分开，公用设备由两套PLC系统各带一半；改造公用系统柜，将原来的一个机架改为两个机架。原有的每个主机架增加一块网络模块，每个上位机也增加一块网卡，改为双网卡。
2.1除灰PLc控制系统优化方案的可行性分析
（1）除灰PLC控制的cpu优化方案的可行性分析：
由于原来设计的1#、2#除灰系统以及公用系统共用1套cpu，一旦cpu出现问题，整个1#、2#除灰系统以及公用系统的六台空压机均停运，将会直接影响到主机的正常运行，另外单台机组检修时也不方便对PLC控制系统进行检查，容易影响运行设备，也不能进行电源切换试验，热备切换试验等。
通过增加一套CPU将1#、2#机组分开控制，并且将公用系统得设备一分为二，分别加入1#、2#除灰系统内并根据空压机的供电情况分配控制，将1#、2#、6#空压机分配至1#除灰系统，3#、4#、5#空压机分配至2#除灰系统，这样大大的提高了除灰系统的稳定性，有利于设备检修。
（2）网络优化方案的可行性分析
原设计的网络，主机架与远程机架之间为单网通讯，在除灰系统正常运行时，由于网络的某个接头接触不良，造成整个除灰系统瘫痪，通过分析，参考其它程控系统的网络控制系统，将单网控制回路改为双网控制，在运行中一旦有一路网络异常，将及时地切换至另一路运行。避免了除灰系统出现非停情况。
同时上位机与主机架的以太网通讯系统，每台上位机都由单网卡改为双网卡，每个主机架也由一个网络模块改为两个网络模块，并且增加了一台交换机，两台交换机分属不同的网段，可以各自独立实现上位机与PLC主机架CPU的通讯。
