Yas Optical Fiber PROFIBUS

Plastic Optical Fiber (POF) PROFIBUS yog kev sib txuas lus kev lag luam uas siv cov tshuab kho qhov muag fiber ntau. Nws yog dav siv nyob rau hauv automation thiab tswj systems.

 

Yas Optical Fiber (POF)yog tsim los ntawm cov ntaub ntawv polymer, feem ntau polymethyl methacrylate (PMMA). Nws nta ib txoj kab uas hla loj dua (feem ntau nyob ib ncig ntawm 1 millimeter), uas yooj yim dua lub teeb liab kis tau tus mob thiab tswj kev ruaj ntseg txawm tias nyob rau hauv kev khoov lossis kev ntxhov siab.

PROFIBUS raws tu qauv: PROFIBUS (Process Field Bus) yog ib txoj kev sib txuas lus dav siv hauv kev lag luam automation. Nws los nyob rau hauv ob lub ntsiab versions: PROFIBUS-DP (Decentralized Peripherals) rau high-ceev cov ntaub ntawv kis tau tus mob thiab PROFIBUS-PA (Process Automation) rau cov txheej txheem tswj daim ntawv thov.

Kev sib txuas lus kho qhov muag nrog POF

Lub teeb kis: Yas Optical Fiber (POF) xa cov ntaub ntawv siv lub teeb pom kev zoo. Cov tub ntxhais ntawm POF, feem ntau yog ua los ntawm polymethyl methacrylate (PMMA), muaj qhov ntsuas siab refractive uas coj lub teeb raws cov fiber ntau. Qhov no txawv ntawm cov kab hluav taws xob ib txwm siv uas siv cov teeb liab hluav taws xob.

Tag nrho Internal Reflection: Nyob rau hauv lub POF, lub teeb nyob rau hauv lub tub ntxhais vim tag nrho cov sab hauv xav txog. Qhov no tshwm sim vim hais tias cov tub ntxhais kawm ntawv muaj ib tug siab dua refractive index piv rau cladding nyob ib ncig ntawm nws. Raws li lub teeb ntsib cov tub ntxhais-cladding ciam teb ntawm ib tug ntiav kaum, nws yog reflected rov qab mus rau hauv lub tub ntxhais, tso cai rau lub teeb mus rau lub sij hawm ntev nrog tsawg heev poob.

Teeb liab kis: Lub teeb pulses xa los ntawm fiber ntau sawv cev rau cov ntaub ntawv raug xa mus. Lub encoding thiab decoding ntawm cov teeb liab teeb liab no yog ua los ntawm transmitters thiab receivers ntawm txhua qhov kawg ntawm fiber. Qhov no ua kom ntseeg tau tias cov ntaub ntawv tuaj yeem xa mus ntev nrog kev ncaj ncees.

 

PROFIBUS raws tu qauv

Kev sib txuas lus raws tu qauv: PROFIBUS (Process Field Bus) yog tus qauv raws tu qauv siv rau kev sib txuas lus hauv kev lag luam. Nws txhawb nqa ob qho tib si digital thiab analog cov ntaub ntawv xa mus thiab yog tsim los txuas ntau yam khoom siv hauv lub network.

Cov ntaub ntawv pauv: PROFIBUS tso cai rau kev sib pauv cov ntaub ntawv ntawm cov khoom siv hauv teb (xws li sensors thiab actuators) thiab cov tswj (xws li PLCs). Nws txhawb nqa cov ntaub ntawv hloov mus rau lub sijhawm tiag tiag thiab pab txhawb kev sib koom ua ke ntawm ntau hom khoom siv rau hauv kev tswj hwm kev sib koom ua ke.

Network Structure: PROFIBUS tes hauj lwm feem ntau ua raws li tus tswv- qhev architecture, qhov twg tus tswv cuab yeej (feem ntau yog PLC) tswj kev sib txuas lus thiab kev xaiv tsa ntawm cov cuab yeej qhev (sensors, actuators). Cov qauv no pab tswj cov ntaub ntawv khiav tsheb thiab ua kom muaj kev sib txuas lus zoo.

Cov ntaub ntawv encoding: Cov ntaub ntawv xa mus rau PROFIBUS tuaj yeem nkag mus thiab xa mus siv ntau txoj hauv kev. Nyob rau hauv cov ntsiab lus ntawm POF PROFIBUS, cov ntaub ntawv encoded yog hloov dua siab tshiab rau hauv lub teeb pulses thiab kis tau los ntawm cov yas optical fiber.

 

Daim ntawv thov

 

Muaj Automation:

Siv los txuas ntau yam khoom siv xws li sensors, actuators, thiab controllers. Nws muaj kev tiv thaiv siab rau EMI kom ntseeg tau cov ntaub ntawv xa mus rau hauv cov tshuab ua haujlwm nyuaj.

Txheej txheem tswj:

Zoo tagnrho rau kev lag luam xws li tshuaj lom neeg, roj, thiab roj, qhov kev sib txuas lus meej thiab txhim khu kev qha yog qhov tseem ceeb. POF PROFIBUS xyuas kom ruaj khov cov ntaub ntawv ntws hauv cov txheej txheem tseem ceeb tswj kev siv.

Hoobkas Automation:

Ua kom yooj yim teeb tsa thiab kho dua tshiab ntawm cov kab ntau lawm, ua tsaug rau nws qhov yooj yim rau nruab. Nws txhawb kev hloov pauv thiab nthuav dav hauv kev tsim khoom ib puag ncig.

Kev xa cov ntaub ntawv nyob rau hauv Harsh Environments:

Haum rau ib puag ncig uas muaj plua plav, noo noo, lossis kub hloov pauv, qhov twg cov xov hlau ib txwm ua tsis tau.

 

 

Qhov zoo

Electromagnetic cuam tshuam (EMI) Resistance: Txij li cov teeb liab teeb tsis cuam tshuam los ntawm electromagnetic cuam tshuam, POF PROFIBUS ua tau zoo nyob rau hauv ib puag ncig nrog siab EMI.

Flexibility thiab yooj yim ntawm kev siv: Cov tub ntxhais txoj kab uas hla loj dua ntawm POF ua rau kev sib txuas thiab txiav ncaj nraim, ua kom yooj yim rau kev xa thiab tu.

Nqi-zoo: POF feem ntau tsis tshua kim dua iav fiber ntau optical, ua rau nws xaiv tus nqi zoo rau kev teeb tsa loj.

Kev nyab xeeb: Optical fiber kis tau tus mob tsis cuam tshuam nrog cov teeb liab hluav taws xob, tshem tawm qhov kev pheej hmoo ntawm cov txim hluav taws xob thiab ua rau nws tsim nyog rau qhov chaw muaj kev phom sij.

 

Yas Optical Fiber (POF) PROFIBUSmuab kev sib txuas lus zoo, nyab xeeb, thiab txhim khu kev qha hauv chaw tsim khoom. Nws zoo heev cuam tshuam tsis kam thiab yooj yim ntawm kev siv ua rau nws yog ib qho kev daws teeb meem zoo tshaj plaws rau ntau daim ntawv thov kev lag luam.
