Cov txiaj ntsig thiab kev coj ua ntawm kev ntsuas lub taub hau digital multihead

Tus Sau: Smartweigh– Multihead Weighter

Hauv kev tsim khoom lag luam ntawm kev siv tshuab automation thiab cov khoom siv hluav taws xob hauv zej zog, feem ntau ntawm cov teeb liab pulse multihead weighers yooj yim siv, thiab cov digital analog multihead weighers rov siv dua ntawm theem no. Vim yog lub teeb liab pulse los ntawm lub hauv paus ntsiab lus ntawm resistor strain force transformation, nws yuav tsum yog Lub teeb liab pulse raug hloov mus rau hauv lub zog ua haujlwm analog simulated lossis lub zog analog simulated raws li lub transmitter ntse. Muaj ntau yam kev paub txog kev ua haujlwm tau khaws cia hauv kev tsim khoom thiab kev ua cov thev naus laus zis, kev them nyiaj thiab kev kho lub zog hluav taws xob, kev hloov pauv pulse thiab lwm yam, yog li daim ntawv thov yog ntau dua. Txawm li cas los xij, nws cov ntaub ntawv tso zis yog me me, qhov deb kis tau luv luv, thiab kev ua haujlwm tiv thaiv kev cuam tshuam tsis zoo. Cov khoom them nyiaj tshiab tau ua ke nrog t-test. Lub zog hluav taws xob circuit kev them nyiaj thiab kev kho cov txheej txheem ua tiav yog qhov nyuaj, uas tsis tsuas yog siv sijhawm thiab kev ua haujlwm, tab sis kuj muaj qhov tseeb them nyiaj tsawg; lub cuab yeej tswj cov ntaub ntawv ntsuas qhov hnyav yog qhov nyuaj, Qhov tsis zoo ntawm Congenital xws li kev teeb tsa tsis yooj yim thiab kev kho tau txiav txim siab qhov kev txhim kho ntawm cov digital thiab analog multihead weighers mus rau digital zaub. Tsuas yog lub module hloov pauv digital sab nraum lub voj voog ntawm lub zog quab yuam yog parasitic, thiab lub teeb liab pulse hloov mus rau lub teeb liab analog.

Yog li ntawd, ib txoj kev hloov pauv digital tau tshwm sim. Ib qho yog hloov cov ntaub ntawv tso zis ntawm lub digital analog multihead weigher mus rau hauv cov teeb liab analog raws li cov ntaub ntawv ntse transmitter ntsia rau hauv nws, uas feem ntau hu ua lub ntse multihead weigher. Uas yog: digital analog multihead weigher + cov ntaub ntawv ntse transmitter = digital zaub multihead weigher. Lub digital zaub sensor txais yuav kev sib xyaw ua ke A / D hloov pauv fais fab mov circuit, ntse cov ntaub ntawv teeb liab kis tau tus mob thiab digital filtering technology. Qhov deb ntawm cov ntaub ntawv teeb liab kis tau tus mob ntawm lub sensor yog deb, thiab kev tiv thaiv kev cuam tshuam yog muaj zog. Lub rooj plaub tiv thaiv, ob yam ntxwv no ib leeg txiav txim siab qhov zoo ntawm nws txoj kev tiv thaiv kev cuam tshuam, thiab txhim kho kev ntseeg siab ntawm lub inductor mus rau qib loj heev.

Lub tshuab ntsuas qhov hnyav ntau lub taub hau digital hloov cov teeb liab sensor ib txwm mus rau hauv lub teeb liab RS485 analog uas muaj qhov tseeb siab, uas tuaj yeem tshem tawm qhov xav tau kev ntsuas, thiab tuaj yeem siv rau hauv kev tsim khoom lag luam tsis siv neeg. Cov ntaub ntawv hais txog lub zog thauj khoom ntawm lub applicator raug hloov mus rau hauv lub teeb liab analog. Lub sensor rub lub zog hnyav hu ua lub plawv ntawm cov khoom siv hnyav, thiab nws cov yam ntxwv txiav txim siab qhov tseeb thiab kev ntseeg tau ntawm cov khoom siv hnyav ntawm qib loj heev. Thaum tsim cov khoom siv hnyav, nws feem ntau nyuaj rau siv cov sensors.

Yuav siv lub qhov hnyav nrog cov yam ntxwv zoo li cas Lub tshuab ntsuas ntau lub taub hau yog qhov tseeb yog ib lub cuab yeej uas hloov cov ntaub ntawv zoo mus rau hauv cov teeb liab hluav taws xob uas tuaj yeem ntsuas tau raws li qhov tseeb. Thaum siv lub sensor, koj yuav tsum xub xav txog qhov chaw ua haujlwm tshwj xeeb uas lub sensor nyob. Qhov no tseem ceeb heev rau kev siv lub sensor kom raug. Nws muaj feem cuam tshuam nrog seb lub sensor puas tuaj yeem ua haujlwm li qub, lwm yam kev nyab xeeb thiab lub sijhawm pabcuam, thiab txawm tias muaj txhua yam khoom siv hluav taws xob. kev ntseeg siab thiab kev ntseeg siab. Yog li yuav ua li cas xaiv lub sensor siab muaj zog rau kev ntsuas thiab rub? Kuv yuav muab cov lus qhia ntxaws ntxaws rau koj hauv qab no.

Cov ntsuas qhov hnyav thiab rub siab siv dav hauv ntau yam khoom siv hlau ntawv ci-hom tiv taus siab ntsuas nrog tus nqi tsis kam ntawm 350Ω, yog li ua ntau yam khoom siv hnyav, uas muaj kev ua tiav siab, kev ntseeg siab zoo thiab tso saib cov ntaub ntawv hauv cov ntawv thov tshwj xeeb. yooj yim thiab lwm yam ntxwv. Ib puag ncig daim ntawv thov ntawm lub ntsuas qhov hnyav rub siab: lub ntsuas qhov hnyav rub siab yog qhov tseeb yog lub cuab yeej tso zis uas hloov cov ntaub ntawv zoo mus rau hauv lub cuab yeej tso zis hluav taws xob uas tuaj yeem ntsuas tau raug. Thaum siv lub sensor, koj yuav tsum xub xav txog qhov chaw ua haujlwm tshwj xeeb uas lub sensor nyob. Qhov no tseem ceeb heev rau kev siv lub sensor kom raug. Nws cuam tshuam nrog seb lub sensor puas tuaj yeem ua haujlwm li qub thiab lwm yam kev nyab xeeb thiab lub sijhawm siv, thiab txawm tias kev ntseeg siab ntawm txhua yam khoom siv hluav taws xob. Kev ruaj ntseg thiab kev nyab xeeb.

Nyob rau hauv qhov xwm txheej ib txwm muaj, qhov kub thiab txias ib puag ncig ua rau muaj teeb meem xws li yaj ntawm cov khoom siv raw, qhov chaw vuam, thiab kev hloov pauv ntawm polyurethane elastomer thermal stress rau lub sensor; pa luam yeeb, plua plav, av noo thiab txias ua rau luv luv ntawm lub sensor; nyob rau hauv ib puag ncig nrog corrosion siab Nws tuaj yeem ua rau puas tsuaj rau polyurethane elastomer ntawm lub sensor lossis ua rau muaj qhov xwm txheej luv luv; lub teb magnetic yuav cuam tshuam rau qhov tso zis ntawm lub sensor. Nyob rau hauv cov yam ntxwv ib puag ncig, koj yuav tsum xaiv lub zog sib phim ntsuas ntau lub taub hau weigher ua ntej koj tuaj yeem xav txog cov cai ntsuas qhov hnyav tsim nyog.
