單片機(jī)應(yīng)用系統(tǒng)抗干擾的研究

針對(duì)生產(chǎn)現(xiàn)場(chǎng)的單片微型計(jì)算機(jī)一般與被測(cè)試對(duì)象、被控制對(duì)象相距較遠(yuǎn)，容易受到各種干擾的侵襲，討論了來(lái)自單片微型計(jì)算機(jī)應(yīng)用系統(tǒng)的內(nèi)部和外部的干擾源、模擬通道、開(kāi)關(guān)通道、供電系統(tǒng)的干擾及解決辦法。利用定時(shí)中斷抗干擾的方案解決了由干擾造成的“死機(jī)”現(xiàn)象，得到了抑制干擾的軟硬件實(shí)現(xiàn)方法。

To the single-chip microcomputer that used for the production field is general with were tested the object distance farther, easily suffer the assault of every kind of interference。this will require the single-chip microcomputer system to have very high and dependable, make it can resist the assault of every kind of interference.Therefore, anti- interference design is the applied system importantly constitute part.This is according to the circumstance of the actual production field, to discussed the inner part of the apply system with the exterior's interference source、analog channel's interference and solution、switch channel's interference and solution ;the power system's interference and solution .And to because the interference result in of" die machine" appearance bring upped soft solution scheme.
