Nyob rau hauv niaj hnub "Smart Factory" era, kev tswj cable feem ntau yog qhov txwv tsis pub muaj tus kws ua haujlwm. Nruab nrab ntawm cov kab hluav taws xob, cov teeb liab cables, thiab cov sensor coj, sab nraub qaum ntawm lub vaj huam sib luag tuaj yeem zoo li "zes" tooj liab. Lawm, lo lus nug tshwm sim:Peb puas tuaj yeem mus wireless?
Yog tias koj tab tom nrhiav kev sib koom ua keindustrial tswj LCD zaubmus rau hauv ib qho kev teeb tsa uas lub cev thaiv tsis tau lossis tsis muaj txiaj ntsig, koj tsis nyob ib leeg. Cia peb nkag mus rau hauv kev sib koom ua ke wireless ua haujlwm li cas, vim li cas nws nyuaj dua li cov neeg siv khoom siv, thiab koj yuav tsum nrhiav dab tsi hauv cov chaw tsim khoom.
Dab tsi yog Industrial Control LCD zaub - Thiab yog vim li cas nws txawv ntawm cov ntxaij vab tshaus tsis tu ncua
Ua ntej peb tham txog Bluetooth, peb yuav tsum tham txog kho vajtse. Ib qho screen industrial tsis yog ib qho rugged version ntawm koj chav nyob TV; nws yog ib tug tsiaj nyaum txawv kiag li.
Grey Screen Design: Tsis yog kab laum, Nws yog qhov tshwj xeeb
Tej zaum koj yuav pom ntau cov ntxaij vab tshaus muaj qhov sib txawv "grey" lossis matte zoo thaum lub hwj chim tawm. Qhov no feem ntau yog txhob txwmindustrial tswj grey screentsim-engineered rau siab sib txawv nyob rau hauv hnyav fluorescent Hoobkas teeb thiab txo glare uas yuav ua rau cov neeg ua hauj lwm yuam kev.
Ua rau ib puag ncig hnyav, tsis muaj chav nyob
Tsis zoo li kev saib xyuas kev lag luam, cov duab no tau tsim kom muaj sia nyob:
Kub kub heev:Kev khiav hauj lwm ntawm $-20\\text{℃}$ mus rau $70\\text{℃}$.
Vibration Resistance:Kev txav mus tas li los ntawm cov tshuab hnyav.
Ntev:Cov khoom xyaw yog muab los ua kom muaj nyob rau 5-10 xyoo, tsis yog 6-lub hlis lifecycle ntawm cov neeg siv khoom smartphone.
Cov lus nug tiag tiag: Koj puas tuaj yeem ntxiv Bluetooth lossis Wireless rau lub LCD muaj?
Lus Teb luv vs. Lus Teb Ntev
Lus Teb luv luv:Yog, kiag li.
Lus Teb Ntev:Nws nyob ntawm tus tsav tsheb. Tsis zoo li lub xov tooj smartphone uas wireless tau koom ua ke rau hauv SoC (System ntawm Chip), ib qho kev lag luam LCD feem ntau tsuas yog lub vaj huam sib luag xwb. Yuav kom tau Bluetooth lossis Wi-Fi, koj xav tau ib qhomuaj LCD nrog Bluetoothmuaj peev xwm ua ke ntawm qib tswj hwm pawg (xws li Android lossis Linux-raws li ARM board).
Ob txoj kev sib koom ua ke
Built -in (Embedded):Lub wireless module yog soldered ncaj qha mus rau lub LCD tsav tsheb board. Qhov no yog sleeker thiab ntau dua vibration-resistant.
Sab nraud Module (Plug-thiab-Play):Siv lub PC ua lag luam lossis lub dongle wireless ntawm USB / RS232. Qhov no yooj yim dua rau kev txhim kho tab sis ntxiv lwm qhov tsis ua tiav.
Kev sib koom ua ke Bluetooth - Nws zoo li zoo li cas ntawm lub Hoobkas Pem Teb
Common Use Cases for Bluetooth in Industrial Displays
Wireless Peripheral Connection:Txuas barcode scanners lossis keyboards yam tsis muaj kab txuas.
Maintenance Diagnostics:Tus kws tshaj lij tuaj yeem sync lawv cov ntsiav tshuaj rau cov zaub kom rub cov ntawv yuam kev yam tsis tau qhib lub txee hluav taws xob.
Sensor Data Hub:Siv BLE (Bluetooth Tsawg Zog) los sau cov ntaub ntawv los ntawm qhov chaw nyob ze lossis qhov ntsuas kub.
Kev txwv koj yuav tsum paub ua ntej koj yuav
Bluetooth ua haujlwm ntawm $2.4\\text{GHz}$ band. Hauv ib lub Hoobkas uas muaj siab -voltage motors thiab cov khoom siv microwave,teeb liab cuam tshuamyog qhov hem tiag tiag. Yog hais tias koj cov zaub yog encased nyob rau hauv ib tug tuab hlau vaj tse, koj yuav xav tau ib tugkav hlau txais xov sab nraudkom tau txais ib qho teeb liab txhua.

Latency, Range, thiab cuam tshuam
Yog kojwireless industrial zaub moduleyog tswj lub caj npab robotic, latency yog koj tus yeeb ncuab. Qhov $100\\text{ms}$ ncua yuav tsis muaj teeb meem rau lub chaw nres tsheb huab cua, tab sis nws yog ib qho kev nyab xeeb ntawm kev tswj kev txav.
EMI, Cov Ntawv Pov Thawj, thiab Cov Khoom Muag Feem Ntau Cov Khoom Muag yuav tsis qhia koj
Ntxiv lub wireless module hloov ib qho "passive" zaub rau hauv ib qho "intentional radiator."
Certification Hurdles:Ibindustrial LCD zaub chaw tsim tshuaj pausyuav tsum xyuas kom lub tsev dhau CE, FCC, thiab RoHS. Ntxiv Wi-Fi txhais tau tias tag nrho lub rooj sib txoos xav tau kev kuaj RF tshiab.
EMI Shielding:Kev lag luam ib puag ncig muaj suab nrov. Lub siab- cov chaw tsim khoom zoo yuav siv cov hlau thaiv nyob ib puag ncig lub wireless module los tiv thaiv LCD lub siab - zaus cov cim los ntawm "choking" lub xov tooj cua Bluetooth/Wi-Fi.
Industrial IoT Trends Tsav Wireless Display Demand
Qhov "Industry 4.0" txav yog tus tsav tsheb tseem ceeb rau cov lus qhia wireless. Cov ntaub ntawv ua lag luam qhia txog qhovindustrial tswj LCD zaubkev ua lag luam tab tom hloov mus rau "Edge Intelligence"-cov ntxaij vab tshaus uas tsis yog qhia cov ntaub ntawv tab sis ua nws thiab xa mus rau huab wirelessly.
Scenario tiag tiag:Ntawm txoj kab tsheb sib dhos, cov khoom siv sab hauv siv Wi-Fi kom tau txais cov lus ceeb toom tiag tiag- lub sijhawm "Andon", tso cai rau cov kab rov ua dua yam tsis muaj ripping hauv pem teb kom khiav Ethernet cables tshiab.
Yuav ua li cas xaiv txoj cai Wireless Industrial Display rau koj qhov project
Daim ntawv txheeb xyuas ua ntej koj tiv tauj ib tus neeg muag khoom
