To taub HMI
HMI yog ib qho khoom siv nquag siv hauv kev lag luam automation thiab kev tsim khoom - tab sis nws ua dab tsi thiab vim li cas? Cia peb ua raws li peb Cov Kev Tiv Thaiv Kev Tiv Thaiv Kev Tshaj Tawm los ntawm qhov tseem ceeb ntawm cov khoom tseem ceeb uas saib xyuas qhov tseem ceeb ntawm kev tsim khoom thiab cov tshuab.
Dab tsi yog Human Machine Interface?
HMI stands rau Human Machine Interface.HMI yog ib qho interface uas tso cai rau tib neeg-tshuab sib cuam tshuam. Nws yog lub rooj vag ntaub ntawv. Yav dhau los, lub teeb ceeb toom thiab lub tswb nrov tau tshwm sim, nrog rau ntau yam kev xaiv tswv yim los ntawm toggles thiab keyboards rau keypads thiab joysticks. Tam sim no, tag nrho cov programmable touchscreens tau dhau los ua tus qauv kev lag luam thiab rau qhov laj thawj zoo. Los ntawm lub vijtsam kov ntawm koj lub xov tooj smartphone mus rau lub dashboard ntawm koj lub tsheb, koj cuam tshuam nrog HMI txhua hnub. Peb tseem yuav tsom mus rau kev tsim khoom tshwj xeeb HMIs.
Nws ua li cas?
Hauv cov ntsiab lus, ntau lub sensors sau cov ntaub ntawv tseem ceeb, uas tom qab ntawd ua tiav los ntawm PLC (Programmable Logic Controller.) HMI nthuav tawm cov ntaub ntawv no pom thiab tso cai rau tus neeg siv teb raws li.
Cov txiaj ntsig ntawm HMI:
HMI muaj ntau cov txiaj ntsig uas txhim kho kev nyab xeeb, kev ua tau zoo thiab tus nqi.
Nov yog cov laj thawj tseem ceeb rau kev siv HMI:
Kev pom zoo:Peb tsis siv lo lus "kev paub yog lub zog" maj mam. Lub kaw lus tuaj yeem muab cov lus qhia txog qhov yuav ua li cas ua ntej cov cuab yeej ua tsis tiav. Kub sensors yuav qhia tau tias overheating. Kev txheeb xyuas cov cuab yeej siv tsis tu ncua tuaj yeem ntes cov ntawv ceeb toom hauv lub sijhawm, tab sis HMI tuaj yeem tau txais thiab kaw lub tswb, qhib lub tswb nrov, thiab tom qab ntawd xa email rau kev ceeb toom tej thaj chaw deb. Tsis tas li ntawd, HMI ua kom yooj yim rau txoj kev saib xyuas. Tag nrho cov ntaub ntawv cuam tshuam tau tshwm sim hauv qhov pom tseeb thiab pom tseeb.
Teb:Kev ceeb toom tam sim thiab kev saib xyuas tej thaj chaw deb tso cai rau 24/7 nkag mus rau lub tshuab tseem ceeb thiab muaj peev xwm teb tau nyob deb. Qee qhov xwm txheej, kev tswj hwm ntawm qhov chaw txo qis qhov xav tau rau cov kws tshaj lij los kov lub tshuab.HMI tes hauj lwm muaj nyob rau hauv ob qho tib si wired thiab wireless daim ntawv tso cai rau cov chaw taws teeb saib thiab tswj. Kev hloov kho sab nraud tuaj yeem ua tam sim ntawd.
Kev nyab xeeb:HMIs muab cov neeg siv ua tiav kev tswj hwm ntawm cov khoom siv los ntawm qhov chaw nyab xeeb thiab xis nyob. Tsis yog nws tsim nyog rau ib tus neeg nkag mus rau qhov xwm txheej txaus ntshai rau kev saib xyuas cov cuab yeej lossis kev hloov kho yooj yim. HMI tso cai rau kev nkag mus rau cov ntaub ntawv dav dav dav dav yam tsis tas yuav tsum nyob ze ntawm lub sensor lossis hloov.
Tus nqi:HMI interfaces coj tus nqi zoo heev rau kev tsim khoom los ntawm kev muaj kev nyab xeeb, kev pom zoo dua qub, thiab kev ua haujlwm zoo dua.HMIs kuj tuaj yeem ua kom muaj txiaj ntsig zoo los ntawm cov txiaj ntsig zoo ib yam. Cov ntaub ntawv tseem ceeb yog yuav luag txhua lub sijhawm ntawm HMI lub vijtsam, thiab yog tias nws tsis raug ntes thiab tshuaj xyuas, nws yog lub sijhawm nkim sijhawm. Los ntawm kev siv kom raug, pov tseg tuaj yeem txo qis, ntau lawm tuaj yeem nce ntxiv, thiab kev saib xyuas tuaj yeem ua haujlwm tsawg dua. Kev ua tau zoo dua yog tus tsav tsheb ntawm kev txo nqi thiab kev txhawb nqa tseem ceeb rau kev nqis peev hauv HMI interface zoo.
