Hauv cov ntawv thov kev lag luam, kev saib xyuas cov chaw taws teeb, thiab cov tshuab ua kom pom tseeb, RS422 tau tshwm sim los ua tus qauv kev sib txuas lus ruaj khov thiab muaj txiaj ntsig zoo. Dav siv nyob rau hauv laser rangefinder modules, nws sib txuas cov peev xwm kis tau tus mob mus ntev nrog lub suab nrov tiv thaiv zoo, ua rau nws yog qhov tseem ceeb hauv kev sib txuas lus niaj hnub.
1. RS422 yog dab tsi?
RS422 (Cov Lus Pom Zoo 422) yog tus qauv sib txuas lus sib txuas lus tsim los ntawm Electronic Industries Alliance (EIA) uas txhais cov teeb liab sib txawv. Tsis zoo li cov tsoos RS232 interface, RS422 siv ib khub ntawm cov teeb liab sib txuas kom xa cov ntaub ntawv. Qhov kev sib kis sib txawv no zoo heev txhim kho lub suab nrov thiab kev sib txuas lus kev ntseeg siab.
2. Cov yam ntxwv tseem ceeb ntawm RS422
Transmission Mode: Differential signaling (twisted khub)
Max kis ceev: 10 Mbps (ntawm luv luv)
Max Transmission Distance: Mus txog 1200 meters (ntawm qhov qis dua)
Max Number of Nodes: 1 tsav tsheb mus rau 10 tus neeg txais
Cov kab hluav taws xob: Feem ntau 4 xov hlau (TX + / TX-, RX+/RX-)
Noise Immunity: Siab (tsim rau complex electromagnetic ib puag ncig)
Kev sib txuas lus hom: Point-to-multipoint (ib tus tsav tsheb mus rau ntau tus neeg txais)
3. Qhov zoo ntawm RS422
①Kev xa mus ntev
RS422 txhawb nqa cov ntaub ntawv xa mus rau qhov deb mus txog 1200 meters, ua rau nws zoo tagnrho rau cov ntawv thov uas ntsuas cov ntaub ntawv yuav tsum tau xa mus rau ntau qhov chaw lossis cov khoom siv.—xws li railway surveying, perimeter monitoring, and warehouse logistics.
②Lub suab nrov tiv thaiv
Ua tsaug rau nws qhov kev taw qhia sib txawv, RS422 tuaj yeem cuam tshuam cov suab nrov nrov, ua rau nws tsim nyog rau qhov chaw muaj suab nrov, xws li cov nroj tsuag muaj kev lag luam lossis kev teeb tsa sab nraum zoov.
③Cov ntaub ntawv siab dua
Txawm hais tias muaj cov kab hluav taws xob ntev ntev los yog hauv cov teeb tsa hluav taws xob nyuaj, RS422 muaj cov ntaub ntawv poob qis dua li cov kev sib txuas lus ib txwm muaj. Qhov no ua kom ruaj khov thiab lub sijhawm ua haujlwm ntawm kev ntsuas qhov deb.
④Ib-rau-Muaj Kev Sib Txuas Lus
RS422 tso cai rau ib tus tswv tsev sib txuas lus nrog ntau tus neeg txais, ua kom muaj txiaj ntsig zoo rau ntau cov qauv sib txawv.
4. Kev siv hauv Laser Rangefinder Modules
RS422 feem ntau yog siv hauv laser rangefinder modules hauv cov xwm txheej hauv qab no:
Drones / Robotic Platforms: Qhov twg cov suab nrov sab hauv yog siab, RS422 ua kom muaj kev sib txuas lus ruaj khov.
Long-Range Perimeter Monitoring: Qhov twg cov ntaub ntawv nyob deb yuav tsum tau xa mus rau lub hauv paus tswj hwm.
Tub Rog / Industrial Systems: Qhov twg kev sib txuas lus kev ntseeg siab yog lub luag haujlwm tseem ceeb.
Ib puag ncig hnyav (piv txwv li, kub thiab av noo): Qhov chaw sib txawv ntawm qhov sib txawv yuav pab tswj cov ntaub ntawv ncaj ncees.
5. Daim ntawv qhia kev xaim thiab cov ntsiab lus tseem ceeb
①Daim duab kab sib txuas:
TX+ (Transmitting Positive)→RX + (Tau txais qhov zoo)
TX-(Kev xa tawm tsis zoo)→RX-(Tau txais qhov tsis zoo)
RX+/RX-: Nyob ntawm seb lub module xav tau kev tawm tswv yim, cov kab no tuaj yeem siv lossis tsis siv.
②Cov kev coj ua zoo tshaj:
Siv cov hlua khi hlua khi hlua khi kom txhim khu kev tiv thaiv kev cuam tshuam.
Xyuas kom meej qhov ntev cable sib phim thiab txiav tawm kom tsis txhob muaj teeb meem xav txog.
Cov cuab yeej txais yuav tsum txhawb nqa RS422 raws tu qauv, lossis RS422 converter yuav tsum tau siv.
RS422 sawv tawm nrog nws cov kev sib kis tau zoo thiab muaj zog, ua rau nws yog ib qho tseem ceeb hauv kev sib txuas lus zoo ntawm laser rangefinder modules. Rau cov neeg siv uas xav tau kev sib kis ntev, cov ntaub ntawv ruaj khov, thiab muaj zog tiv thaiv lub suab nrov, xaiv lub module nrog RS422 kev txhawb nqa yog undoubtedly ib tug txhim khu kev qha thiab yav tom ntej-pov thawj peev.
