Lub hardware yam ntawm lub industrial computer
Ntau yam khoom sib txuas txuas ntxiv los ntawm CompactPCI tus qauv yog qhov me me, xws li PMC tus ntxhais daim npav, uas tuaj yeem ua tiav qhov nthuav dav yam tsis muaj qhov tuab ntawm daim npav. Nrog 1U, 2U, 4U, 8U, 9U, 12U thiab lwm yam kev xaiv chassis, lub kaw lus tuaj yeem paub ntau yam kev siv hauv tib tus qauv khib, uas yooj yim rau kev tswj hwm. Tsis tas li ntawd, txhua lub chassis tuaj yeem teeb tsa nrog mus txog 21 teeb ntawm I / O, thiab ntau pawg ntawm cov khoom siv hluav taws xob rov ua dua. Cov "tub rau khoom-hom" kub-swappable tsim tau txais los ntawm cov neeg rau zaub mov system yog ntsia los ntawm sab xub ntiag, uas muab kev yooj yim rau kev saib xyuas. Kev ntseeg siab siab kiv cua tsis muaj CPU, txo qis MTTR (Lub Sijhawm Kho Kom Zoo) thiab lwm yam qauv muab kev lees paub rau kev ua tiav ntawm kev ntseeg siab ntawm kev sib txuas lus.
CompactPCI yog raws li PICMG2.0 specification. Nws cov yam ntxwv hluav taws xob zoo ib yam li lub tsheb npav PCI, yog li tus neeg siv software tau sib xws nrog cov PCs zoo tib yam, thiab cov npav PCI peripheral uas twb muaj lawm kuj tuaj yeem hloov pauv tau yooj yim rau CompactPCI platform. CompactPCI siv 2 hli high-density pinhole bus connectors. Piv nrog PCI phaib siv cov ntiv tes kub sib txuas, nws muaj cov yam ntxwv ntawm kev sib txuas txhim khu kev qha thiab ua tiav airtightness, thiab daim npav muaj kev poob siab thiab kev tiv thaiv corrosion. Tsis tas li ntawd, daim npav CompactPCI tau txais cov qauv Eurocard uas tau sim hauv thaj tsam ntau tshaj 20 xyoo. Daim npav European tus qauv txais kev teeb tsa ntsug thiab cov qauv tsim tawm pem hauv ntej, uas txhim kho cov cua sov dissipation, poob siab tsis kam thiab kho yooj yim ntawm daim npav. Tshwj xeeb, nws muaj cov txiaj ntsig hauv qab no:
Lub tshuab computer muaj zog muaj zog vibration kuj
Daim npav CompactPCI tau kho nrog cov kev taw qhia nce thiab nqis, thiab sab pem hauv ntej ntawm daim npav txuas nrog lub nraub qaum los ntawm cov cua nruj pinhole txuas, txhua qhov txuas muaj lub zog ntawm 10kg. Daim npav tuaj yeem kho rau lub chassis los ntawm lub vaj huam sib luag screws. Sab pem hauv ntej thiab nram qab ntawm daim npav CompactPCI tau kho thiab nqis, yog li lub kaw lus muaj kev poob siab siab.
Txhawb nqa nyob ntsaws thiab tshem tawm ntawm daim npav
Lub nraub qaum ntawm CompactPCI siv cov qauv ntev, nruab nrab thiab luv pins, uas lub hwj chim thiab av pins yog qhov ntev tshaj plaws, uas tuaj yeem xyuas kom meej tias daim npav tuaj yeem muab ntxig thiab rub tawm yam xyuam xim. Tsis tas li ntawd, pawg thawj coj xaiv teeb liab IDSEL, BD_SEL pins yog qhov luv tshaj plaws, lub kaw lus tuaj yeem siv cov teeb liab no kom paub seb daim npav puas nyob rau hauv cov txheej txheem ntawm kev ntxig lossis rub tawm. Tsis tas li ntawd, CompactPCI tau tsim cov txheej txheem kub-plug kho vajtse thiab software tswj kev sib cuam tshuam los xyuas kom meej cov txiaj ntsig ntawm daim npav kub-plug txheej txheem.
Txhawb kev xaim rov qab kom yooj yim xaim
Daim npav teeb liab kab ntawm CompactPCI tsis tas yuav tsum tau kos tawm ntawm lub vaj huam sib luag pem hauv ntej ntawm daim npav, tab sis cov kab teeb liab tuaj yeem rub tawm los ntawm qhov kawg nrog lub rooj tsav xwm adapter los ntawm lub nraub qaum. Thaum hloov daim npav, tsis tas yuav hloov cov teeb liab kab, uas txo cov kev ua haujlwm ntawm kev hloov daim npav thiab txo qhov tshwm sim ntawm qhov yuam kev los ntawm kev hloov cov kab teeb liab. Tsis tas li ntawd, lub teeb liab kab yog kos los ntawm qhov kawg ntawm lub nraub qaum, thiab lub hauv ntej kawg ntawm lub cuab yeej yuav zoo nkauj dua.
Daim npav yog ntsia tau vertically, uas yog qhov zoo rau cov cua sov dissipation
Daim npav CompactPCI txais cov qauv daim npav European qauv, daim npav tau teeb tsa vertically, thiab cov cua txias ntawm lub kaw lus tau tshuab los ntawm hauv qab mus rau sab saum toj, uas ua raws li lub hauv paus ntsiab lus ntawm huab cua convection thiab muaj cov cua kub zoo.
Daim npav CompactPCI muaj cov yam ntxwv hluav taws xob zoo dua
Cov pins thiab connectors ntawm CompactPCI backplane yog tag nrho cov kub-plated, thiab lub siab tshaj plaws ntev ntawm lub teeb liab kab, impedance ntawm lub PCB board, lub decoupling capacitor, thiab cov tsis kam ntawm PCI rub-up resistor yog nruj me ntsis txwv. Yog li ntawd, cov yam ntxwv hluav taws xob ntawm CompactPCI zoo dua li PCI kev lag luam computer zoo tib yam. Ib qho kev tsheb npav CompactPCI tuaj yeem txhawb nqa txog 7 PCI li, thaum lub khoos phis tawj kev lag luam zoo tib yam tuaj yeem txhawb nqa 4 PCI li.
Zoo tiv thaiv corrosion thiab electromagnetic shielding
CompactPCI siv 2 hli airtight pinhole bus connectors, thiab ntsev tsuag, kua qaub pos huab thiab them plua plav tsis tuaj yeem corrode lub tsheb npav. Tsis tas li ntawd, CompactPCI's all-aluminium alloy case plhaub thiab daim npav U-zoo li lub caij nplooj ntoos hlav tuaj yeem muab kev tiv thaiv electromagnetic zoo rau lub cev. Zoo anti-static. Qhov qis kawg ntawm daim npav CompactPCI muaj cov kab hluav taws xob zoo li qub, thiab hluav taws xob zoo li qub tuaj yeem xa tawm mus rau hauv av. Tsis tas li ntawd, CompactPCI qhia tias lub hauv paus ntsiab lus ntawm qhov system raug cais tawm ntawm lub chassis hauv av kom lub kaw lus tsis muaj kev cuam tshuam sab nraud. Txawm li cas los xij, lub khoos phis tawj kev lag luam raws li PICMG1.0 tsis tuaj yeem cais cov chassis hauv av thiab cov laj thawj hauv av.
2 Software yam
Ntxiv rau qhov ua tau zoo nrog Microsoft Windows operating system, vim tias CompactPCI tau txais kev ua haujlwm qhib thiab muaj cov tsav tsheb nplua nuj thiab cov cuab yeej tsim kho, nws tuaj yeem tsis tsuas yog siv rau kev txhim kho ntawm ntau lub sijhawm hloov pauv cov ntawv thov, tab sis kuj yuav tsum tau tsim. ntawm cov chaw lag luam loj (xws li IBM, HP, Cov ntawv thov hauv xov tooj qub tau tsim los ntawm ntau yam RTOS (Real-Time OS, xws li Solaris, Linux, VxWorks, thiab lwm yam) ntawm SUN, thiab lwm yam) tuaj yeem hloov tau yooj yim rau CompactPCI. platform, xws li Billing System, unified Message (Unified Messaging), Streaming Server, thiab lwm yam.
3 Qhov System upgrade
Vim muaj hluav taws xob thauj khoom, txhua lub tsheb npav CompactPCI raug txwv rau yim qhov. Tab sis nrog PCI-PCI choj chips los ntawm ntau lub tuam txhab, nws yog ib qho yooj yim los mus nce tus naj npawb ntawm cov slots. Tus choj chip no ua haujlwm raws li hom "super buffer" nti. Kev cuam tshuam, plug-and-play cov ntaub ntawv thiab cov ntaub ntawv feem ntau tuaj yeem yooj yim thiab cia li hloov mus los ntawm tus choj no. CPU thiab peripherals ntawm Compact PCI yog tib yam li cov txheej txheem PCI, yog li lub operating system, tsav tsheb thiab cov ntawv thov tsis xav tias qhov sib txawv ntawm ob. Hloov daim npav PCI tus qauv rau hauv daim npav Compact PCI yuav luag tsis muaj kev tsim kho dua tshiab. Tsuas yog lub cev rov faib nws.
Ntxiv mus, qhov ceev ntawm CPU nce qib feem ntau sai dua li ntawm I / O subsystem. Lub CompactPCI architecture tso cai rau cov neeg siv khoom hloov kho tsuas yog ib feem ntawm CPU motherboard yam tsis tau kov lwm yam I / O. Nws yog qhov qhib kev txhawb nqa los ntawm lub ntiaj teb, yog li nws muaj kev txhawb nqa kev txhawb nqa txaus thiab kev txhawb nqa rau cov khoom siv peripheral.
