有了成績要馬上忘掉，這樣才不會自尋煩惱；有了錯誤要時刻記住，這樣才不會重蹈覆轍；有了機遇要馬上抓住，這樣才不會失去機會；有了困難要尋找對策，這樣才能迎刃而解。

在原來控制系統(tǒng)基礎上增加一套PLC雙機熱備系統(tǒng)，使除灰控制系統(tǒng)分開，公用設備由兩套PLC系統(tǒng)各帶一半；改造公用系統(tǒng)柜，將原來的一個機架改為兩個機架。原有的每個主機架增加一塊網(wǎng)絡模塊，每個上位機也增加一塊網(wǎng)卡，改為雙網(wǎng)卡。
2.1除灰PLc控制系統(tǒng)優(yōu)化方案的可行性分析
（1）除灰PLC控制的cpu優(yōu)化方案的可行性分析：
由于原來設計的1#、2#除灰系統(tǒng)以及公用系統(tǒng)共用1套cpu，一旦cpu出現(xiàn)問題，整個1#、2#除灰系統(tǒng)以及公用系統(tǒng)的六臺空壓機均停運，將會直接影響到主機的正常運行，另外單臺機組檢修時也不方便對PLC控制系統(tǒng)進行檢查，容易影響運行設備，也不能進行電源切換試驗，熱備切換試驗等。
通過增加一套CPU將1#、2#機組分開控制，并且將公用系統(tǒng)得設備一分為二，分別加入1#、2#除灰系統(tǒng)內(nèi)并根據(jù)空壓機的供電情況分配控制，將1#、2#、6#空壓機分配至1#除灰系統(tǒng)，3#、4#、5#空壓機分配至2#除灰系統(tǒng)，這樣大大的提高了除灰系統(tǒng)的穩(wěn)定性，有利于設備檢修。
（2）網(wǎng)絡優(yōu)化方案的可行性分析
原設計的網(wǎng)絡，主機架與遠程機架之間為單網(wǎng)通訊，在除灰系統(tǒng)正常運行時，由于網(wǎng)絡的某個接頭接觸不良，造成整個除灰系統(tǒng)癱瘓，通過分析，參考其它程控系統(tǒng)的網(wǎng)絡控制系統(tǒng)，將單網(wǎng)控制回路改為雙網(wǎng)控制，在運行中一旦有一路網(wǎng)絡異常，將及時地切換至另一路運行。避免了除灰系統(tǒng)出現(xiàn)非停情況。
同時上位機與主機架的以太網(wǎng)通訊系統(tǒng)，每臺上位機都由單網(wǎng)卡改為雙網(wǎng)卡，每個主機架也由一個網(wǎng)絡模塊改為兩個網(wǎng)絡模塊，并且增加了一臺交換機，兩臺交換機分屬不同的網(wǎng)段，可以各自獨立實現(xiàn)上位機與PLC主機架CPU的通訊。
