Cov cuab yeej tshaj lij li autocad hluav taws xob lossis Epllan muab cov cim kev qiv ntawv, kev ntsuas kev ua yuam kev, thiab kev tswj hwm qhov kev kho tshiab, thiab kho kev kho mob yooj yim. Rau cov txheej txheem yooj yim lossis cov phiaj xwm tswv yim, cov cuab yeej siv dav dav xws li Draw.io, LucidChart, lossis txawm tias PowerPoint tuaj yeem tsim cov duab kos kom txaus. Kev xuas tes kos duab tes ua haujlwm rau thawj zaug kev tawm tsam tab sis tsis haum rau cov ntaub ntawv kawg. Qhov tseem ceeb yog siv cov cim hluav taws xob cov cim tsis hais txog cov cuab yeej-kev cai cim uas "tsim kev nkag siab rau lwm tus.
Dab tsi yog qhov kev ua yuam kev ntau tshaj plaws hauv Bess daim duab kos duab?
Qhia ntau dhau ntawm ib qho pom. Cov engineers feem ntau sim ua kom tsim cov duab kos npe uas suav nrog cov txheej txheem txheej txheem system uas suav nrog cov txheej txheem txheej txheem system, cov lus qhia tshwj xeeb, thiab xaim cov ntsiab lus ib txhij. Qhov no tsim kev pom kev sib tw sib tshooj uas swb daim duab lub hom phiaj. Txoj kev zoo dua: Tsim cov hierarchy ntawm cov duab kos duab ntawm cov qib sib txawv. Cia cov saib pib nrog kev nkag siab ntau thiab laum cia raws li xav tau ntau dua li yuam cov ntaub ntawv los ntawm ntom, tag nrho-enccompassing daim duab.
Daim duab yuav pab tau li cas thaum Bess daws teeb meem?
Daim duab kos ua kom muaj kev sib txig sib cais los ntawm kev pab cov ua haujlwm kab mob rov qab rau cov tsos mob. Yog tias voltage nyeem yog txawv txav, daim duab qhia ntsuas ntsuas ntsuas thiab cov khoom siv dab tsi nyob ntawm lawv. Yog hais tias lub subsystem yuav tsis sib txuas lus, daim duab qhia cov teeb liab txoj kev thiab muaj peev xwm tawg cov ntsiab lus. Txawm li cas los xij, cov duab kos ua haujlwm zoo tshaj plaws ua ke nrog cov txheej txheem daws teeb meem uas ntxiv cov ntaub ntawv kuaj mob rau cov ntaub ntawv pom. Daim duab teb "qhov twg" cov lus nug; Cov txheej txheem ntxiv "Yuav ua li cas thiaj kuaj" thiab "qhov txhais tau li cas".
Yuav tsum bess daim duab kos duab qhia software / tswj cov cuab yeej system?
Nws nyob ntawm lub hom phiaj. Hluav Taws Xob Hluav Taws Xob yuav tsum qhia cov khoom siv hluav taws xob lub cev thiab kev sib txuas - lawv tsis zoo tagnrho rau sawv cev software logic. Tswj lub cev tsim nyog tau txais cov ntaub ntawv tsim nyog (Network DireGrams rau kev sib txuas lus, FlowCharts rau cov txheej txheem kev hloov pauv ntawm kev hloov pauv hom. Qee cov ntaub ntawv bess suav nrog cov duab hluav taws xob: cov duab hluav taws xob rau cov khoom siv kho hluav taws xob ntxiv cais cov kev tswj cov kos duab rau software. Sim qhia ob qho tib si hauv ib daim duab ib txwm muaj ntau dua li nws paub meej.
Tseem Ceeb Takaways
Kev tshawb nrhiav kev pom zoo
Bess daim duab kos qhia tshwj xeeb qhia txog cov teeb meem tsim qauv tsim qauv ua tsis tau muaj cov ntsiab lus tsis yooj yim, thiab cov teeb meem kev nyab xeeb ploj lawm, thiab cov kev sib raug zoo thiab cov kev sib txuam sib xyaw.
Daim duab kos muaj kev txwv pom meej thiab yuav tsum yog ib feem ntawm cov ntaub ntawv sib xyaw ua ke rau cov kev ntsuas thiab cov ntawv sau cov ntsiab lus ntawm cov txheej txheem thiab kev daws teeb meem kev daws teeb meem.
Tus nqi muaj tseeb ntawm kev tsim cov bess duas cov duab kos tsis yog tsuas yog kev sib txuas lus ntawm kev txiav txim siab tsim qauv thaum lawv ua teeb meem txuas ntxiv.
