Hauv kev sib txuas lus niaj hnub thiab cov ntaub ntawv kis tau tus mob, USB thiab RS485 yog ob qho tib si cov qauv kev sib tshuam. USB tau dav siv rau kev sib txuas ntawm tus kheej lub khoos phis tawj nrog ntau yam khoom siv vim nws lub ntsaws thiab ua si thiab cov yam ntxwv sib kis ceev ceev; RS485, ntawm qhov tod tes, nyob hauv ib qho chaw hauv kev lag luam automation, kev saib xyuas tej thaj chaw deb thiab lwm qhov chaw vim nws cov yam ntxwv ntawm kev ncua deb, sib txawv kis tau tus mob, thiab ntau yam khoom siv sib txuas. Yog li, yuav ua li cas USB rau RS485 converter txuas ob qhov sib txawv ntawm cov qauv sib txawv ua ke?
1, Lub hauv paus ntsiab lus ntawm USB rau RS485 converter
USB rau RS485 converter, raws li lub npe qhia, yog ib tug ntaus ntawv uas yuav hloov cov ntaub ntawv ntawm USB thiab RS485 interfaces. Nws lub luag haujlwm tseem ceeb yog hloov cov ntaub ntawv tawm ntawm USB interface mus rau theem teeb liab uas tuaj yeem lees paub los ntawm RS485 interface, thiab rov ua dua. Lub converter muaj txoj kev tsim Circuit Court thiab tswj cov logic kom ua tiav kev hloov pauv ntawm ntau qib, cov ntaub ntawv tawm tswv yim, thiab kev sib txuas lus raws tu qauv.
Kev hloov dua siab tshiab
USB interface siv cov teeb liab sib txawv, thaum RS485 kuj siv cov teeb liab sib txawv. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb hauv cov qauv ntawm ob, nrog USB feem ntau yog 3.3V lossis 5V, thaum RS485 feem ntau yog li ntawm ± 2V rau ± 6V. Ib lub teeb liab txias Circuit Court yuav tsum tau nyob rau hauv lub converter los hloov lub USB teeb liab theem rau RS485 tus qauv, thiab vice versa.
Cov ntaub ntawv hom conversion
Cov ntaub ntawv kis tau tus mob ntawm USB interface feem ntau yog siv cov pob ntawv kis tau tus mob, suav nrog pib me ntsis, cov ntaub ntawv me ntsis, kos me ntsis, thiab nres me ntsis. RS485 hloov tau yooj yim dua thiab tuaj yeem txhawb ntau hom ntaub ntawv. Lub converter yuav tsum muaj peev xwm paub thiab hloov ob hom ntaub ntawv sib txawv kom paub meej cov ntaub ntawv xa mus.
Kev sib txuas lus raws tu qauv hloov dua siab tshiab
USB interfaces feem ntau ua raws li USB kev sib txuas lus raws tu qauv, suav nrog cov qauv xws li USB 1.1, USB 2.0, thiab USB 3.0. RS485, ntawm qhov tod tes, tsis muaj cov txheej txheem kev sib txuas lus sib koom ua ke thiab tso siab ntxiv rau cov khoom siv raws tu qauv hauv cov ntawv thov tshwj xeeb. Lub converter yuav tsum muaj tej yam kev cai parsing peev xwm thiab yuav tsum tau hloov ntawm txawv raws tu qauv.
2, Daim ntawv thov scenarios ntawm USB rau RS485 converter
kev lag luam automation
Hauv kev lag luam automation, RS485 tau siv dav rau kev sib txuas lus ntawm cov sensors, actuators, PLCs, thiab lwm yam khoom siv vim nws txoj kev sib kis mus ntev thiab ntau yam khoom siv sib txuas. Los ntawm USB rau RS485 converter, engineers tau yooj yim txuas cov khoos phis tawj rau cov khoom siv no rau kev saib xyuas, kev debugging, lossis cov ntaub ntawv xa mus.
Kev saib xyuas thaj chaw deb
Hauv kev saib xyuas tej thaj chaw deb, feem ntau yuav tsum tau xa cov ntaub ntawv sau los ntawm cov khoom siv pem hauv ntej xws li cov koob yees duab thiab cov sensors mus rau qhov chaw saib xyuas tej thaj chaw deb. USB rau RS485 converter tuaj yeem ua tus choj rau cov ntaub ntawv xa mus, xa cov ntaub ntawv los ntawm cov khoom siv hauv ntej mus rau qhov chaw saib xyuas los ntawm RS485 network, ua tiav cov chaw taws teeb saib xyuas lub sijhawm.
Kev sau cov ntaub ntawv thiab kev txheeb xyuas
Hauv thaj chaw xws li kev tshawb fawb txog kev tshawb fawb thiab kev saib xyuas ib puag ncig, nws yog qhov tsim nyog los sau ntau yam ntaub ntawv ntawm qhov chaw. USB rau RS485 converter tuaj yeem pab cov neeg tshawb nrhiav yooj yim hloov cov ntaub ntawv khaws cia rau hauv lub computer los ntawm USB interface rau kev ua cov ntaub ntawv txuas ntxiv thiab tshuaj xyuas.
