单片机应用系统抗干扰的研究

针对生产现场的单片微型计算机一般与被测试对象、被控制对象相距较远，容易受到各种干扰的侵袭，讨论了来自单片微型计算机应用系统的内部和外部的干扰源、模拟通道、开关通道、供电系统的干扰及解决办法。利用定时中断抗干扰的方案解决了由干扰造成的“死机”现象，得到了抑制干扰的软硬件实现方法。

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.
