2. Cov twj paj nruag digital
Digital tswj cov cuab yeej siv tau cov cuab yeej tswj hwm (DCS), programmable logic tswj hwm (IRC), thiab kev nyab xeeb tswj cov tshuab (FSC).
Nyob rau hauv 1960s, raws li cov txheej txheem kev lag luam tau dhau los tau ua rau cov ntaub ntawv sib txuas lus, ua haujlwm sib txuas lus, ua tiav qib siab- qib ntsuas, thiab txhim kho kev tswj hwm qib. Cov twj paj nruag analog ib leeg yuav tsis tau raws li cov lus thov no, ua rau lub khoos phis tawm ntawm kev tswj hwm cov tshuab uas tswj tau ntau yam ntawm kev tswj cov txheej txheem sib xyaw. Txawm li cas los xij, lub siab siab ntawm kev tswj hwm cov haujlwm tseem muaj kev pheej hmoo ntawm cov xwm txheej. Yog tias lub computer tswj kev ua tsis tiav, kev tswj hwm, thiab kev ua haujlwm yuav tsum tsis tseg, tsim kev ntau heev thiab muaj peev xwm ua rau muaj kev sib tw loj heev.
Tom qab xyoo 1970, kev tawm tsam ntawm loj- Cov thev naus laus zis thiab cov thev naus laus zis ua ke, ua rau kev sib xyaw ua ke, xws li cov chaw tswj tau faib (DCS). DCS tau txais qhov zoo ntawm cov twj paj nruag tso pa thiab tswj lub computer tswj. Thaum khaws cov zaub hauv paus nruab nrab thiab kev ua haujlwm nrog rau kev tswj hwm kev tswj hwm, nws yog kho kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov kev tswj hwm. Qhov no tau ua tiav los ntawm kev faib cov microprocess raws li tswj cov haujlwm lossis thaj chaw. Txhua lub microprocessing -} Cov chaw nres tsheb tswj tau tuaj yeem tswj ob peb los ua kom ntau ntau rau loops. Ntau yam kev tswj hwm ntau tau sib koom ua ke rau kev tswj hwm tag nrho cov txheej txheem ntau lawm, yog li paub txog kev tswj hwm kev pheej hmoo. Lub tsev raws li qhov no, cov ntaub ntawv ntau tshaj plaws yog kev sib txuas lus ntawm cov ntaub ntawv kev sib txuas lus thiab chaw nres tsheb hauv cov ntaub ntawv Central tswj, qhov twg cov ntaub ntawv no tau tso tawm lossis sau tseg. Ib txhij, hauv kev ua kom sib haum nrog siab dua- Cov khoos phis tawm txheej txheem thiab kev tswj hwm txheej txheem thiab kev tswj hwm ntawm cov txheej txheem ntau lawm.
Faib cov tshuab tswj kev tswj hwm, batch (sib qab) tswj, cov ntaub ntawv tau txais, raws li kev tswj hwm kev ua haujlwm, sib txuas ua haujlwm nrog cov txheej txheem ntau lawm. Cov kab ke no tseem ua rau tus kheej - lub peev xwm, muaj peev xwm soj ntsuam cov khoom siv kho vajtse thiab software. Thaum soj ntsuam qhov txhaum, lawv ua rau pom kev zoo thiab pom tau pom thaum pom qhov chaw uas tsis muaj tseeb.
Ib tug raug faib tawm kev tswj hwm cov qauv muaj xws li kev ntsuas chaw nres tsheb, kev sib txuas lus, thiab cov khoom siv hluav taws xob xws li cov tshuab luam ntawv.
Thaum lub sij hawm kev txhim kho tom ntej, kev tswj hwm thiab kev sib txuas lus ntawm cov kev tswj hwm hluav taws xob tau dhau los ua kom zoo dua thiab qauv. Raws li lawv thawj tswj hwm kev ua haujlwm, programmable cov kev tswj hwm logic (PLCS) tshwm sim los ntawm DCS Systems {}}}} li cov khoom siv tshwj xeeb tshaj tawm. Ameslikas tsim los hloov cov khaub ncaws tsoos -}} Siv ob lub tswv yim thiab cov zis paib raws li kev teeb tsa. Lawv tau ua raws, ua ntu zus, kev suav, suav, thiab kev ua xam laij ntawv los ntawm software programming, ua rau lawv haum rau cov kev sib tw software. Qhov kev txhais tau ntawm PLCS yog lawv "programmability" {{{}}} Kev tswj xyuas schemes tuaj yeem hloov kho qhov kev hloov kho. Lawv txoj kev ntseeg tau, yooj yim, kev ua haujlwm ceev, thiab muaj peev xwm tswj hwm cov surpass cov txheej txheem uas tau ua tiav nrog cov relay circuits.
PLCS tau hloov zuj zus sai, sib koom ua ke Kev Tswj Xyuas Kev Tsim Kho Kev Lag Luam Lub caij no, DCS lub tshuab tau txais yuav cov yam ntxwv ua plc txuj ci thaum txhim kho kev ua tiav thiab ua tiav cov haujlwm muaj zog. Qhov kev sib cav sib ceg no yog nqaim qhov sib txawv ntawm DCS thiab PLC, plooj lawv thaj tsam. Raws li kev faib tawm cov tshuab txuas ntxiv mus evve {{}} kev sib xyaw ua ke ntawm cov txheej txheem kev tswj hwm, cov qauv kev sib koom ua ke ntawm cov txheej txheem kev tswj hwm thiab ua tiav cov txiaj ntsig kev lag luam thiab nyiaj txiag.
