Kev Paub Txog Kev Lag Luam

Hauv kev lag luam niaj hnub no, kev lag luam computers ua lub luag haujlwm tseem ceeb. Ntawm ntau hom kev tswj hwm kev lag luam, kev sib koom ua ke hauv kev lag luam hauv computer tau maj mam tshwm sim thiab qhia lawv cov txiaj ntsig tshwj xeeb hauv kev lag luam. Kab lus no yuav tshawb txog cov ntsiab lus, yam ntxwv, thiab kev cia siab ntawm kev lag luam hauv computer hauv kev lag luam.

Phau ntawv rugged yog ib qho qauv tshwj xeeb ntawm lub laptop tsim los tiv thaiv ib puag ncig huab cua thiab mob hnyav. Hauv ntau qhov kev lag luam thiab kev lag luam, xws li kev ua haujlwm hauv teb, aerospace, mining, thiab lwm yam, kev ruaj ntseg thiab kev ntseeg siab ntawm phau ntawv rugged yog qhov tseem ceeb. Ntawm lawv, qhov kub thiab txias ua haujlwm yog qhov tseem ceeb los xyuas kom meej tias kev ua haujlwm ib txwm muaj ntawm phau ntawv rugged. Yog li, dab tsi yog qhov kev khiav hauj lwm kub ntawm ib phau ntawv rugged?

Portable industrial computer yog ib lub computer muaj zog thiab txhim khu kev qha. Nws tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig kev lag luam raws li kev tswj hwm kev lag luam. Nyob rau tib lub sijhawm, vim nws qhov kev txav tau yooj yim, nws yog qhov tsim nyog rau kev ua haujlwm hauv thaj chaw ib puag ncig. Piv nrog rau lub khoos phis tawj laptop, qhov nthuav dav ntawm lub khoos phis tawj nqa tau muaj qhov txiaj ntsig zoo.

Nyob rau hauv lub tshav pob ntawm niaj hnub industrial automation, embedded industrial computers thiab industrial computers yog ob lub ntsiab lus tseem ceeb. Embedded industrial computers yog ib qho kev faib tawm ntawm cov khoom siv hauv computer, thaum cov computers muaj ntau lub tswv yim uas suav nrog cov khoos phis tawj siv computer.

Lub sijhawm kawg peb tau tham txog lub ntsiab lus ntawm "Puas yog lub khoos phis tawj muaj lub hauv paus ntawm automation? PLC puas tuaj yeem ua tau?" Hauv tshooj no, peb yuav txuas ntxiv cov ncauj lus no thiab tham txog lub ntsiab lus ntawm kev lag luam computers thiab PLCs yog lub ntsiab ntawm kev txhim kho yav tom ntej;

Industrial computers yog cov khoos phis tawj tshwj xeeb uas siv rau kev tswj hwm kev lag luam. Lawv cov keeb kwm kev loj hlob tuaj yeem taug qab mus rau xyoo 1950s. Nrog rau txoj kev loj hlob ntawm industrial thov thiab nce ntawm industrial automation, lawv maj mam coj cov duab. Los ntawm qhov ntxov tshaj plaws kev lag luam tswj systems cia siab rau analog technology thiab electromechanical technology, mus txog rau thaum pib ntawm lub digital era, thiab thaum kawg mus rau lub nce ntawm lub PLC era, lub evolution ntawm industrial computers nyob rau hauv kev sib txuas ntawm software thiab kho vajtse yog zoo siab heev; lub sij hawm no peb yuav tham txog "txawm hais tias muaj computers yog lub hauv paus ntawm automation thiab seb PLC puas ua tau nws";

Nkag siab qhov sib txawv ntawm SSD (Solid-State Drive) thiab flash drive yog qhov tseem ceeb. Ob leeg ua rau siv lub cim xeeb flash, ib hom kev nco tsis hloov pauv uas tuaj yeem txuag cov ntaub ntawv txawm tias tom qab lub hwj chim kaw. Muaj ob hom loj: NAND flash thiab NOR flash. Cov hom no yog qhov tseem ceeb rau txhua qhov gadget ua haujlwm li cas thiab nws ua haujlwm li cas.

Ib qhov chaw nres nkoj serial yog lub khoos phis tawj tseem ceeb txuas rau kev sib txuas lus ntawm cov khoom siv. Nws txawv ntawm cov chaw nres nkoj sib txuas, uas xa cov ntaub ntawv tag nrho ib zaug. Hloov chaw, qhov chaw nres nkoj serial xa cov ntaub ntawv ib qho me ntsis ntawm ib lub sijhawm, hla ib qho channel.

Cov khoos phis tawj muaj peev xwm ua lub luag haujlwm tseem ceeb hauv kev lag luam tes hauj lwm thiab tseem ceeb heev rau kev ua kom muaj kev ntseeg siab, kev ruaj ntseg, thiab kev ua haujlwm ntawm kev lag luam. Kab lus no yuav qhia ntau lub luag haujlwm tseem ceeb ntawm cov khoos phis tawj hauv kev lag luam hauv kev lag luam.

Hauv kev tswj hwm kev lag luam, kev lag luam portable computers muaj kev sib koom ua ke thiab muaj zog, siv dav hauv ntau cov kab ntau lawm. Xaiv txoj cai muaj lub khoos phis tawj portable yog qhov tseem ceeb los xyuas kom muaj kev ruaj ntseg ntawm cov kab ntau lawm thiab txhim kho kev tsim khoom.
