Composing of EMC module in large-scale electronic equipment group

To ensure the normal w ork in the compl icated elect romag net ir env ir onment , the intr oduct ion of EMC techno logy as a module into large-scale elect ronic equipment gr oup in the w hole life cycle was ver y necessary . A kind of st ructure plan for EMC module w as proposed, and the feasibility of the const itution pr oject w as demonstr ated combined w ith the analy sis of the funct ion st ructur e and w or k process o f submodules. The key technolog y involv ed in the module realizat ion w as discussed in detail. Mathemat ic model w hich EMC fo recast submodules depends on w as analy zed and progr ammer f low as w ell as majo r measure fo r EMC design w as presented. Some primary measur es fo r EMC design w ere pr opo sed and the real ization metho d for automatic detect ion of EMI module was of fered. Operat ing effect s show s that the str ucture plan proposed in this paper is rational and effect iv e.
