硬件措施：

? ? 主要模塊均采用大規(guī)模或超大規(guī)模集成電路，大量開關(guān)動作由無觸點的電子存儲器完成，I/O系統(tǒng)設(shè)計有完善的通道保護(hù)和信號調(diào)理電路。

? ? ①屏蔽——對電源變壓器、CPU、編程器等主要部件，采用導(dǎo)電、導(dǎo)磁良好的材料進(jìn)行屏蔽，以防外界干擾。

? ? ②濾波——對供電系統(tǒng)及輸入線路采用多種形式的濾波，如LC或π型濾波網(wǎng)絡(luò)，以消除或抑制高頻干擾，也削弱了各種模塊之間的相互影響。

? ? ③電源調(diào)整與保護(hù)——對微處理器這個核心部件所需的+5V電源，采用多級濾波，并用集成電壓調(diào)整器進(jìn)行調(diào)整，以適應(yīng)交流電網(wǎng)的波動和過電壓、欠電壓的影響。

? ? ④隔離——在微處理器與I/O電路之間，采用光電隔離措施，有效地隔離I/O接口與CPU之間電的聯(lián)系，減少故障和誤動作；各I/O口之間亦彼此隔離。

? ? ⑤采用模塊式結(jié)構(gòu)——這種結(jié)構(gòu)有助于在故障情況下短時修復(fù)。一旦查出某一模塊出現(xiàn)故障，能迅速更換，使系統(tǒng)恢復(fù)正常工作；同時也有助于加快查找故障原因。
