Thaum pib, feem ntau cov ntawv thov Hmi tau mob siab rau kev sib tw ua haujlwm tshwj xeeb hauv ib qho khoom siv xwb. Ib qho kev lag luam uas tau raug siv los hloov cov nyees khawm, ntsuas, gauges loj, thiab thumbwheels vaj huam sib luag yooj yim. Nws yuav sib txuas lus nrog lub tshuab tswj hwm (feem ntau yog cov txheej txheem txheej txheem sau npe (PLC) dhau ntawm cov khoom siv sib txuas lus (PLC)
Cov kev pab cuam ntawm cov ntsiab lus zoo no yog ua rau lub PC, thiab cov kev ua tiav tau rub tawm HMIS siv cov haujlwm tsim qauv (OS) thiab cov khoom siv tau kim. Thaum tau teeb meem, lub embedded HMI tsis tuaj yeem hloov kho lossis hloov pauv tshwj tsis yog nws tau reprogrammed hauv PC, HMI yuav raug kaw, thiab txoj haujlwm tshiab tau thauj khoom.
Txawm hais tias cov nqi siab thiab cov nqi siab no, embedded Hmis muaj kev txhim kho zoo nkauj, ua tau zoo, thiab siv cov neeg tsav tsheb uas twb muaj lawm.
Qhov tseem ceeb txuag nyiaj tseem ceeb tshaj plaws yog vim muaj kev tshem tawm ntawm PLC inputions thiab tawm rau txhua tus neeg teb xov tooj interface cuab yeej. Nrog lub vaj huam sib luag nyuaj {{1} mounted tus neeg teb xov xwm incutace, txhua lub teeb yuav tsum tau sib xws disc tso zis, thiab txhua tus thumbhauniver los txuas nrog analog plc cov tswv yim. Tsis tsuas yog qhov no kim heev rau pem hauv ntej, tab sis nws yog ib tug npau suav phem.
Nrog rau tus neeg tsav tsheb hardwirer hardwer, tsuas yog ntxiv cov teeb pom kev zoo yuav tsum tau muab cov teeb pom kev zoo, txuas cov teeb rov qab rau PlC cov txiaj ntsig, thiab reprogramming lub PLC. Qhov no xav tias muaj cov vaj huam sib luag txaus txaus thiab spare PlC tawm. Nyob rau hauv kev sib piv, txoj haujlwm ntawm reprroogramming lub HMI thiab PLC ntxiv ntxiv cov cim qhia ntxiv yog qhov yooj yim.
Rau cov cav tov thiab lwm cov ntawv thov uas yuav tsum muaj ntau cov nyees khawm, teeb pom kev zoo, thiab thumbhauns lossis thumbhauns lossis thotion}}}}} Cov HMis tuaj yeem muab cov nqi nyiaj tseem ceeb. Tsis tas li ntawd, embedded Hmis yuav muaj peev xwm muab cov txiaj ntsig zoo xws li kev lag luam thiab cov phiaj xwm, uas tuaj yeem hloov cov ntaubntawv cov ntaub ntawv.
Hmi evolution
Txhawm rau hloov zuj zus los ntawm cov neeg teb xov tooj cua hauv kev sib cais rau cov kev hloov pauv ntawm Scada (piv txwv li, PCs thiab Windows ua haujlwm).
Thaum xyoo 1990s, PCs tau qhia rau cov ntsiab lus thiab cov nroj tsuag, feem ntau hosting Scada thiab cov software zoo sib xws hauv pawg. Tom qab nyob rau hauv lub xyoo pua, kev siv PCS tau qhia rau kev siv HMI cov ntawv thov ua kom tau tsiv tsiv mus rau hauv chav tsev kawm ntawv.
Tom qab qee qhov pib tsis kam nyob hauv khw muag khoom vim yog cov qauv tsis zoo, cov pc- kev tuag lub ntsej muag thiab lwm yam txiaj ntsig Hmi siab heev.
Kev tig mus ncig tom ntej tshwm sim hauv thaj chaw muaj feem cuam tshuam ntawm bandwidth thiab networking. Ua tsaug rau kev nthuav dav ntawm ethernet lub peev xwm, bandwidth nce siab ntxiv, cia cov kab ke ua ke kom yooj yim txuas ua ke, yog li ua tiav Automation Silos.
Cov lus qhia ntawm cov qauv TCP xws li TCP / IP thiab cov khoom siv qhib Scada ntau dua thiab cov chaw ua haujlwm pcs rau cov ntaub ntawv nkag mus hauv khw.
Ua raws li kev taw qhia ntawm PC - raws li lub Microsoft Windows CE OS Redatic Scada nruab rau cov khoom muaj peev xwm ntawm cov peev txheej. Raws li qhov tshwm sim, ntau tus neeg muag khoom tau sib tw los tsim cov qes- tus nqi platform, tsav tsheb nqes tus nqi kho vajtse.
Nyob rau tib lub sijhawm, Is Taws Nem tau pua txoj kev rau cov ntaub ntawv sib pauv ntawm cov khoom siv dav dav ntawm cov khoom siv kho vajtse, suav nrog embeddedded, PLCS, thiab Scada. Embedded thiab Advanced Hmi Cov pob khoom software tau pib muab cov chaw taws teeb nkag, ua ntej los ntawm browsers thiab tom qab ntawd los ntawm kev thov. Qhov no yog ntau tshaj li qhov yooj yim rau kev ua haujlwm thiab cov tswj hwm muaj peev xwm saib cov ntaub ntawv ntawm txhua qhov chaw tau pab cov nroj tsuag khiav tau ntau yam nrog tsawg zog.
Los ntawm kev npaj ua lub Windows thiab nws cov khoom siv Windows ua haujlwm raws li cov qauv kev ua haujlwm zoo li cov qauv kev ua haujlwm zoo nkauj thiab ua haujlwm zoo li} thiab Windows} Cov pob khoom software. Rau ntau tus neeg siv, embedded Hmis tam sim no tshaj li qhov txaus rau lawv cov ntawv thov, tso cai rau hloov los ntawm pc - raws HMIS. Qhov kev tshwm sim hauv cov nqi nyiaj txiag loj vim tias txhua yam muaj feem nrog cov software uas pheej yig dua, suav nrog cov ntawv tso cai refrish, thiab cov phiaj xwm lub hom phiaj.
Siv PC -} Raws HMI hauv ib puag ncig kev lag luam yuav tsum muaj PC thiab saib xyuas. Nrog Embedded Hmi, ib lub platform siv hluav taws xob pab tau tib lub luag haujlwm ntawm tus nqi qis dua. Niaj hnub nimno webs software tuaj yeem nyob rau hauv cov platform uas tsis tshua muaj kev cuam tshuam nrog cov neeg siv khoom, tab sis tseem muaj cov khoom siv hloov chaw, tab sis tseem ceeb {} Lub sijhawm tshaj tawm thiab kev lag luam ntawm qhov ntsuas qhov tseem ceeb.
Chaw taws teeb nkag thiab cov neeg siv -} tus phooj ywg interfaces
Engineers thiab cov neeg khiav lag luam Cia siab tias yuav siv tib yam yooj yim thiab ua haujlwm uas lawv tau txais los ntawm lawv cov khoom siv ntiag tug, tshwj xeeb yog thaum nws los txog rau HMIS. Niaj hnub no cov smartphones thiab ntsiav tshuaj teeb tsa cov kev cia siab rau wireless sib txuas, nws tsis muaj kev xav tsis thoob uas cov neeg siv hluav taws xob tau ua ib qho tseem ceeb hauv kev lag luam hmi. Qhov tseeb, muaj ntau lub koom haum yog txiav cov nqi los ntawm Instituting "Nqa koj tus kheej ntaus ntawv" (Besod) cov cai ua haujlwm siv lawv tus kheej smartphones thiab cov ntsiav tshuaj li mobile hmi.
Hmi cov neeg siv tam sim no tau hu rau tus neeg teb xov tooj sib sau ua ke thoob plaws txhua pab kiag li lawm. Lawv xav tau HMI software -} Seb - screens rau smartphones thiab ntsiav tshuaj, tsis hais txog kev ua haujlwm smartphones thiab ntsiav tshuaj, tsis hais txog kev ua haujlwm.
Nyob rau hauv teb, ib tug xov tooj ntawm embedded hmi software software software muab cov peev xwm no. Cov kev daws teeb meem software tsim tsim cov ntawv thov rau cov khoom siv
Los ntawm muab cov kev txhawb nqa HTML5, cov kev daws teeb meem no tau yooj yim rau lub ntsiab lus Cov neeg siv HTML5 frees los ntawm qeeb internet browser rub tawm lossis tos lub hlis twg los xij Raws li Bynod cov cai tau dhau los ua ntau dhau los, HTML5 kev txhawb nqa yuav ua ib qho kev ua haujlwm siv ntau yam ntawm cov ntawv thov kev ua haujlwm.
Tsis yog tsuas yog yuav tsum tau nthuav tawm hauv tib txoj kev hla cov cuab yeej los txhim kho cov neeg ua haujlwm ua haujlwm, tab sis nws tseem yuav tsum yooj yim rau kev nkag mus thiab tswj hwm. Thaum multi {{1} kov tshuab kov tau zoo li lwm tus "Kuv dhau lawm"
Raws li ntau dua thiab ntau cov khoom siv tes tau siv los khaws cov ntaub ntawv, cov neeg siv xav tau kev paub thiab nrawm nrog cov ntaub ntawv. Multi - kov nqa cov cuab yeej paub ntawm cov tshuab smartphones thiab ntsiav tshuaj rau kev kos duab, zooming, khoom siv- down. Hloov chaw ntawm kev nkim sij hawm txav ntawm cov ntxaij vab tshaus nrog cov neeg siv tsim nyog, tom qab ntawd rub tawm hauv thaj chaw muaj teeb meem thiab hloov hauv vib nas this.
Lub neej yav tom ntej yog thoob plaws peb
Kev nce qib hauv HMis tau nthuav dav cov kev muaj kev lag luam hauv cov cuab yeej interface, thiab raws li cov ntawv thov tau hloov ib hnub ntawm lub sijhawm tshiab, xws li kev pom. Qhov no kuj yuav tseem ntau dua thaum tham txog HMI.
Cov hnub ntawm cais tawm, kim thiab tsim cov haujlwm tsawg tsawg thiab nkag mus rau ntawm tus neeg siv khoom pem hauv ntej tau txais sai sai. Niaj hnub no cov kev siv HMI no muaj ntau lub peev xwm ntawm lub peev xwm Scada thiab lwm yam kev thov zoo nkauj uas yuav tsum tau siv lub platform kev lag luam.
Thaum cov neeg ua haujlwm tseem yuav xav tau ntawm lub khw hauv pem teb hauv qee kis, kev sib txuas lus nrog rau cov neeg ua haujlwm hauv zos thiab HMIS yuav nce kev ua haujlwm hauv zos thiab kev tsim khoom. Lub neej yav tom ntej no yuav tsis hloov rau tib neeg, tab sis yuav nce mus kom lawv mus cuag cov nroj tsuag thiab tsob nroj nroj tsuag kom tau txais kev ua haujlwm raws li xav tau.
