硬件措施:
主要模塊均采用大規(guī);虺笠(guī)模集成電路,大量開關動作由無觸點的電子存儲器完成,i/o系統(tǒng)設計有完善的通道保護和信號調理電路。
、 屏蔽——對電源變壓器、CPU、編程器等主要部件,采用導電、導磁良好的材料進行屏蔽,以防外界干擾。
、 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,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。
、 電源調整與保護——對微處理器這個核心部件所需的+5v電源,采用多級濾波,并用集成電壓調整器進行調整,以適應交流電網(wǎng)的波動和過電壓、欠電壓的影響。
、 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。
、 采用模塊式結構——這種結構有助于在故障情況下短時修復。一旦查出某一模塊出現(xiàn)故障,能迅速更換,使系統(tǒng)恢復正常工作;同時也有助于加快查找故障原因。
