Hauv kev lag luam automation platform, PLC thiab cov khoos phis tawj muaj ob hom kev tswj xyuas uas tib neeg yuav tsum tau hais, thiab lawv yog cov qauv tsim ntawm feem ntau automation systems. Kev tsim kho thev naus laus zis tshiab ntawm PLC thiab lub khoos phis tawj muaj kev lag luam yog qhov kev qhia zoo tshaj plaws ntawm cov kws tshaj lij cov kev xav tau rau kev tsim cov ntawv thov kev ua haujlwm: cov txheej txheem kho vajtse ntawm tus maub los, thiab cov neeg siv ntau yam kev tswj hwm tau hloov pauv los ntawm software.
Lub khoos phis tawj muaj peev xwm siv lub npav PCI ntawm lub khoos phis tawj dav dav thiab siv cov khoom siv ua haujlwm kom nthuav dav cov ntsiab lus tswj I / O kom ua tiav cov qauv tswj kom yooj yim rau kev tswj hwm lub computer. Nws muaj cov yam ntxwv ntawm daim ntawv thov kev lag luam, thiab tib lub sijhawm, nws siv software ib puag ncig ntawm PC zoo heev, thiab cov neeg siv tau yooj yim xaiv cov khoom muab los ntawm ntau lub tuam txhab.
Txoj kev loj hlob ntawm kev lag luam hauv computer sib raug rau kev sib txuas ntawm cov khoom thiab cov ntaub ntawv loj ntawm Internet ntawm Yam. Ntxiv nrog rau kev ntes kab rov tav, kev sau, thiab kev sib koom ua ke ntawm cov ntaub ntawv ntawm qhov chaw, nws tseem yuav tsum tau sib txuas lus nrog cov phiaj xwm hauv ob qho kev qhia, thiab ntawm qhov kev npaj, cov ntaub ntawv hloov pauv mus rau hauv cov ntaub ntawv thiab ntxiv mus. Tom qab txoj kev npaj ua lag luam, qhov kev txiav txim thim rov qab tau muab coj los qhia txog kev ua tiav ntawm kev sib koom ua ke. Nyob rau hauv cov txheej txheem no, ntxiv rau kev ua si lub luag hauj lwm ntawm qhov ruaj khov thiab txhim khu kev qha hardware cornerstone, lub computer muaj kev lag luam yuav tsum txuas ntxiv kev sib koom ua ke software thiab firmware, hloov cov ntaub ntawv ntws ntawm kev sib txawv thiab kev sib tham, thiab ua lub luag haujlwm ntawm qhov nruab nrab ntawm txhua yam. cov ntaub ntawv.
Nyob rau hauv lub neej yav tom ntej, cov qauv kev lag luam ntawm kev lag luam hauv computer yuav hloov pauv, los ntawm cov khoom siv ntshiab niaj hnub no mus rau kev tswj hwm kev tswj hwm nrog qib siab ntawm kev koom ua ke ntawm cov khoom siv kho vajtse, firmware thiab software. Qhov ntawd yog hais tias, ntxiv rau kev ua tiav lub luag haujlwm ntawm lub tshuab tsis siv neeg yav tom ntej, lub khoos phis tawj muaj nyob hauv Nyij Pooj kuj xav tau kev sib koom ua ke software thiab firmware mus rau txhua txoj hauv kev, thiab txuas cov saw ecological uas tsis muaj qhov xav tau.
Kev ua kom zoo thiab txhim kho cov txheej txheem kev lag luam yog ib txoj hauv kev tseem ceeb los ua raws li kev tsim khoom hauv Suav teb uas twb muaj lawm thiab kev txhim kho. Raws li lub luag haujlwm tseem ceeb rau automation thiab kev txhais cov ntaub ntawv, lub khoos phis tawj muaj peev xwm yuav inevitably tsim nrog kev nthuav dav thiab dav automation ntawm ib puag ncig. Nyob rau hauv txoj kev npaj ntawm kev lag luam computer platform, ntxiv rau kev muab cov neeg siv khoom ruaj khov thiab txhim khu kev qha cov khoom siv hauv computer, nws tseem yuav tso siab rau kev txaus siab ntawm software, kom cov neeg siv khoom tuaj yeem ua raws li cov ntawv thov davhlau ya nyob twg ntawm tus nqi tsawg kawg nkaus.
Yam tseem ceeb rau kev xaiv kev lag luam keyboards
Kev hloov pauv kev lag luam yog Ethernet hloov architecture siv hauv kev tswj hwm kev lag luam. Vim tias lub vev xaib tus qauv siv, nws qhov kev qhib tau zoo, daim ntawv thov dav thiab tus nqi qis, thiab cov khoom siv pob tshab thiab cov TCP / IP raws tu qauv siv. Ethernet tau dhau los ua tus qauv kev sib txuas lus tseem ceeb rau kev tswj hwm kev lag luam. Nws yog tus nqi tsim nyog kev lag luam kev sib txuas lus tsim tshwj xeeb los ua kom tau raws li cov kev xav tau ntawm cov ntawv thov kev lag luam yooj yim thiab hloov tau. Muab kev lag luam zoo-qib zoo xws li kev vibration tsis kam, siab / tsis kub tsis kam, plua plav, tiv thaiv xob laim, thiab lwm yam, thiab sib xyaw ua ke ntau yam kev nplua nuj xws li routing, hloov, kev ruaj ntseg, thiab lwm yam, txhawm rau txhim kho kev ntseeg tau thiab kev ruaj ntseg ntawm lub vev xaib muaj. nplooj ntawv, thiab kom muaj peev xwm ua tau raws li qhov xav tau ntawm cov nroog nyab xeeb. , kev thauj mus los ntse, kev soj ntsuam sab nraum zoov thiab lwm yam yuav tsum tau xa mus rau hauv cov xwm txheej phem.
Lub ntsiab tseem ceeb uas yuav tsum tau xav txog thaum xaiv lub tshuab hloov tshuab:
1. Kev ntseeg tau
Hauv cov xwm txheej hauv kev lag luam, kev ntseeg siab yog qhov tseem ceeb. Cov yam ntxwv muaj feem xyuam rau kev ntseeg tau ntawm cov khoom lag luam yog: kev ua siab ntev ntawm lub tsev kho vajtse rau kev ua haujlwm: xws li kev txwv kev ua haujlwm kub, EMC electromagnetic compatibility, xob laim tiv thaiv qib, kev teeb tsa thiab lub zog siv hluav taws xob, kiv cua tsim, tsis siv neeg rov ua haujlwm, kev kuaj mob thiab kev txawj rov qab, thiab lwm yam. . Nyob rau hauv parameter zoo ntawm cov khoom, nws yuav tsum muaj feem xyuam rau cov ncauj lus kom ntxaws cov duab ntawm kev ua hauj lwm kub txwv, electromagnetic tiv thaiv, thiab hluav taws xob tiv thaiv qib.
2. Sijhawm sijhawm
Yuav muaj qee yam qeeb hauv kev xa cov ntaub ntawv nplooj ntawv web. Yog li ntawd, thaum xaiv ib qho kev lag luam Ethernet hloov, nws yog ib qho tsim nyog yuav tau xav txog kev hloov mus rau qhov chaw nres nkoj qeeb hauv cov txheej txheem xa cov ntaub ntawv. Nyob rau hauv tus txheej txheem chaw tsim tshuaj paus qhov kev tswj tsis siv neeg, lub sij hawm teb uas lub system tuaj yeem zam tsis pub dhau 10 milliseconds. Yog li ntawd, thaum xaiv qhov hloov pauv, nws yuav tsum tau muab sau tseg tias tus nqi ntawm qhov hloov chaw nres nkoj ncua yuav tsum tsis pub tshaj 10 microseconds.
3. Kev sib haum xeeb
Muaj Ethernet keyboards thiab lwm yam khoom siv Ethernet yuav tsum muaj peev xwm sib txuas lus siv tus qauv TCP / IP raws tu qauv. Nyob rau hauv txhua rooj plaub, yuav tsum tsis muaj incompatibility ntawm industrial Ethernet architectures thiab coj mus muag Ethernet architectures. Ua raws li kev tswj hwm kev lag luam hauv tsheb npav sib txawv, kev lag luam Ethernet architecture yuav tsum muaj peev xwm sib xws nrog nws.
Tsis tas li ntawd, nyob rau hauv tus txheej txheem ntawm kev xaiv ib tug muaj kev hloov, tus neeg siv yuav tsum tau xaiv ib tug tsim nyog twisted khub los yog kho qhov muag fiber interface raws li ib co yooj yim yuav tsum tau xws li kis tau tus mob ncua sij hawm thiab kis bandwidth. Hauv qee lub tsev xws li txuas txuas video terminals, wireless base stations, thiab lwm yam., PoE fais fab mov ntawm Ethernet hloov tuaj yeem xaiv rau kev yooj yim ntawm kev xaim.
Cov kev hloov hauv kev lag luam muaj cov yam ntxwv ntawm kev ua haujlwm zoo thiab tuaj yeem ua haujlwm hnyav. Cov khoom lag luam yog nplua nuj thiab kev tsim kho chaw nres nkoj yooj yim, uas tuaj yeem ua tau raws li daim ntawv thov kev xav tau ntawm ntau lub platforms. Cov khoom siv dav dav tsim qauv, kev tiv thaiv qib tsis qis dua IP30, kev txhawb nqa tus qauv thiab cov tswv cuab ntawm lub nplhaib network redundancy raws tu qauv.
