1. Lub tshuab computer yog dab tsi?
Embedded industrial PCs thiab cov ntsiav tshuaj ua lag luam tag nrho-hauv-ib lub khoos phis tawj tau siv ntau zaus thiab muaj ntau heev. Yog li dab tsi yog lub computer industrial? Qhov tseeb, lub tshuab computer yog lub computer. Hauv cov ntsiab lus yooj yim, nws tau muab faib ua peb hom: tus kheej PC, server, thiab lub computer muaj. Industrial computer yog siv rau industrial ntau lawm tswj. Yog li ntawd, piv nrog tus kheej PCs thiab servers, qhov chaw ua haujlwm ntawm cov khoos phis tawj muaj zog heev, thiab cov kev xav tau rau cov ntaub ntawv kev ruaj ntseg kuj tseem siab heev. Lub khoos phis tawj muaj kev lag luam yuav tsum muaj kev tiv thaiv yooj yim, suav nrog kev txhawb nqa, plua plav, tsis muaj dej, tiv thaiv corrosion, thiab tiv thaiv hluav taws xob. Nyob rau tib lub sijhawm, cov khoos phis tawj tswj kev lag luam muaj cov kev xav tau siab heev rau kev ua haujlwm txuas ntxiv, thiab cov khoos phis tawj tswj kev lag luam feem ntau yuav tsum tau kho tus kheej kom ua tau raws li cov kev xav tau ntawm cov khoom siv sab nraud.
2. Dab tsi yog ib qho kev lag luam hauv computer motherboard?
Hais txog architecture, tus kheej PC txais ATX architecture; thiab cov kev lag luam hauv computer motherboard txais ntau yam kev qhia tshwj xeeb, xws li ATX, MIN-ITX, LPX, POS, thiab lwm yam. Ntau qhov tshwj xeeb tuaj yeem hloov kho raws li qhov xav tau ntawm ntau qhov chaw sib txawv. Vim hais tias PC motherboards raug rau PCI specifications, lawv feem ntau muab 3 PCI slots; Tus naj npawb ntawm PCIs ntawm kev tswj hwm cov motherboard tuaj yeem muaj ntau dua 5, thiab lub peev xwm tsav yuav tsis raug txo kom tsawg. Nyob rau tib lub sijhawm, nws txhawb ntau qhov sib cuam tshuam, xws li MiniPCI-E, PC104 ntxiv, ntau yam COM interfaces, kos GPIO tsheb npav, dual zaub ua haujlwm nrog LVDS, HDMI, DVI interfaces, ua haujlwm puv npo thiab kev sib koom ua ke hauv qab, nthuav dav ntxiv, txhawb nqa. rau ntau ISA, PCI, MINIPCI txuas ntxiv. Lub PCB ntawm lub khoos phis tawj kev lag luam yuav siv lub rooj tsav xwm PCB nrog ntau tshaj 6 txheej, uas yog 2 txheej ntau dua li PCB motherboard. Kev tsim ntau txheej PCB Circuit Board tsim tuaj yeem txhim kho lub peev xwm ntawm tag nrho pawg thawj coj los tiv thaiv electromagnetic cuam tshuam thiab ntxiv dag zog rau kev ruaj ntseg ntawm lub motherboard. Ntxiv mus, lub neej voj voog ntawm motherboard yog ntev heev. Ordinary motherboards thiab accessories tsuas yog yuav tsum tau ua kom tau raws li 2 xyoos, thiab qhov hloov tshiab yog ceev heev; cov kev lag luam hauv computer motherboard tshwj xeeb heev txog cov khoom siv, xws li cov khoom siv hluav taws xob yuav tshwm sim ntawm cov khoom siv computer motherboard kom ntseeg tau tias nws tuaj yeem siv tau ntev hauv qhov chaw hnyav.
Tus nqi ntawm cov motherboard zoo tib yam yog qhov loj heev, thaum lawv tsim, lawv tsim, thiab tsis muaj kev hloov kho los ntawm cov neeg siv khoom. Kev lag luam hauv computer motherboard yog qhov sib txawv kiag li, uas tuaj yeem ua tau raws li qhov xav tau tshwj xeeb ntawm qee cov neeg siv khoom thiab paub cov neeg siv kev hloov kho. Kev khiav hauj lwm ib puag ncig ntawm lub tshuab computer yog hnyav, nrog cov sij hawm ua haujlwm ntev, huab cua tsis zoo, av noo, kev co, plua plav, hluav taws xob, kub kub, thiab lwm yam, nws tuaj yeem ua haujlwm ruaj khov ntawm -10 degrees thiab 60 degrees. Feem ntau cov lag luam motherboards tsuas yog khiav ntawm sab hauv tsev kub ntawm 5 txog 40 degrees. Cov khoos phis tawj qub tsis muaj kev tiv thaiv kev ua haujlwm tom qab tsoo; embedded industrial motherboards yuav cia li rov pib dua thaum tus saib xyuas ntsib kev sib tsoo, tiv thaiv kev kub ntxhov thiab lwm yam haujlwm, thiab ua txhua yam kom ntseeg tau tias muaj kev ruaj ntseg siab ntawm cov kab ke hauv ib puag ncig hnyav.
3. Dab tsi yog lub tshuab computer tsis muaj kiv cua?
Box computer, fanless industrial computer, fanless embedded industrial computer yog tiag tiag tib hom kev lag luam computer. Lub computer muaj cov qauv compact thiab tau tshwj xeeb muaj zog. Raws li cov cuab yeej kho kom zoo, nws tuaj yeem ua haujlwm tau zoo hauv ib puag ncig kev lag luam.
Nyob rau thaum ntxov 90s ntawm lub xyoo pua xeem, cov tshuab zoo sib xws tau tsim los ntawm cov tuam txhab siv computer hauv Tebchaws Meskas. Cov khoom siv yog tus nqi qis, me me, txhim khu kev qha hauv kev ua haujlwm, thiab kev ua haujlwm zoo ntawm tus nqi, thiab nws tau txuas ntxiv mus tob rau hauv daim ntawv thov.
Nta ntawm fanless embedded industrial computer:
Feem ntau ntawm lawv yuav siv tag nrho cov txheej txheem hlau ua lag luam-qib chassis uas tuaj yeem txhim kho lub peev xwm tiv thaiv electromagnetic cuam tshuam. Ntxiv nrog rau nws qhov muaj zog tiv thaiv hluav taws xob cuam tshuam muaj peev xwm, cov khoom lag luam hauv computer no tuaj yeem ua haujlwm tsis muaj kev cuam tshuam hauv ib puag ncig sab nraum zoov hauv qab hnub ntev. Feem ntau cov kiv cua tsis muaj kev tswj hwm kev lag luam siv cov khoom siv hluav taws xob muaj kev ntseeg siab heev nrog qhov hluav taws xob thiab kev tiv thaiv tam sim no. Tsis tas li ntawd, tsis muaj kiv cua nyob rau hauv lub chassis, thiab ib tug tsis muaj kiv cua integrated tshav kub dissipation tsim yog saws. Lub tswv yim tshiab multi-faceted tshav kub dissipation tsim tuaj yeem tshem tawm cov cua sov hauv lub sijhawm. Lub cev kuj yog me me thiab zoo heev, yooj yim rau nruab thiab tshem tawm. Yog tias lub tshuab tawg, lub sijhawm saib xyuas tuaj yeem rov pib dua.
