Qhov zoo ntawm multihead weighter yog txiav txim siab thiab kev soj ntsuam ntawm tsib qhov yuam kev ua rau ntau lub taub hau hnyav

Author: Smartweigh-Multihead Weighter

Lub multihead weighter yog ib qho cuab yeej uas hloov cov ntaub ntawv zoo rau hauv cov teeb liab hluav taws xob uas tuaj yeem ntsuas qhov tseeb. Thaum siv lub sensor, nws yog ib qho tsim nyog yuav tsum xav txog qhov chaw ua haujlwm tshwj xeeb uas lub sensor nyob. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev siv ntau lub taub hau hnyav. Nws muaj feem xyuam rau seb lub sensor tuaj yeem ua haujlwm li cas thiab lwm yam kev nyab xeeb thiab siv sijhawm, thiab txawm tias muaj tag nrho cov khoom siv hluav taws xob. kev ntseeg siab thiab kev nyab xeeb. Nyob rau hauv cov ntsiab lus tseem ceeb thiab kev ntsuam xyuas cov txheej txheem ntawm multihead weighter qhov tseem ceeb ntawm kev ua tau zoo, muaj qhov sib txawv ntawm cov qauv qub thiab lub teb chaws tshiab.

Lub multihead weigher txawv qhov zoo thiab qhov tsis zoo ntawm qhov hnyav. Tom qab daim ntawv thov mus sij hawm ntev, lub qhov hnyav yuav raug txwv. Feem ntau, peb yuav tsum daws cov teeb meem zoo li no raws li qhov ntsuas ntawm lub ntsuas qhov hnyav. Tab sis qee zaum, tsis muaj teeb meem li cas los ntsuas, lub cev ntsuas tsis tuaj yeem rov qab los. Nyob rau lub sijhawm no, txhua tus neeg yuav tsum tau ua tiav kev soj ntsuam ntxaws los ntawm txhua theem ntawm lub koom haum hnyav, thiab cov khoom tseem ceeb hauv lub koom haum hnyav yog lub cev hnyav. Nyob rau theem no, lub cev hnyav feem ntau siv qhov ntsuas qhov ntsuas qhov ntsuas ntau lub taub hau hnyav (simulation) ua qhov tseem ceeb ntawm lub koom haum hnyav. Nws siv lub hauv paus ntsiab lus ntawm Wheatstone choj los hloov cov ntaub ntawv nyhav nyhav rau hauv lub teeb liab hluav taws xob ntawm kev hloov pauv. Yeej muaj plaub kab. , cov tswv yim yog 5-10V txhawb kev ua hauj lwm voltage (lub hwj chim mov system ua hauj lwm voltage), cov zis yog“mV”Nws yog cov ntaub ntawv nyhav nyhav ntawm lub lag luam.

Tom ntej no, kuv yuav qhia koj yuav ua li cas txiav txim siab qhov zoo thiab qhov tsis zoo ntawm multihead weighters: 1: Saib xyuas thiab xyuas seb qhov zoo li ntawm lub sensor yog deformed, tawg, thiab lwm yam. Yog tias qhov no tshwm sim, koj yuav tsum hu rau cov chaw tsim khoom los hloov lub sensor tshiab. 2: Txoj kev ntsuas I / O yog txhawm rau nrhiav qhov kev sib txuas ntawm qhov ntsuas qhov kawg hauv qhov ntsuas qhov ntsuas (multihead weighter meter), thiab ntsuas ntsuas ntsuas tau txuas nrog lub zog hluav taws xob. Raws li ib txwm muaj, qhov txhawb kev ua haujlwm voltage (EXC + mus rau EXC- nruab nrab) yog 5-10V, qhov tso zis hluav taws xob (nruab nrab ntawm SIG + thiab SIG-) yog ze rau 0 thaum lub tshuab ua haujlwm tag nrho, uas yog qis dua qhov siab tshaj plaws ntawm lub plawv. lub sensor. (Lub sensor yog loj dua thiab lub plawv tso zis = txhawb kev ua hauj lwm voltage * sensor rhiab heev, thiab lub multihead weighter sensor rhiab heev yog feem ntau 1mV / V.) Yog hais tias lub sensor ntau tshaj qhov no, hu rau lub chaw muab kev pab los thov kev hloov lub sensor.

Peb: Inductor tsis kam ntsuas txoj kev: Ua kom raug ntsuas qhov ntsuas qhov ntsuas ntawm qhov ntsuas, thiab txiav txim siab qhov zoo ntawm lub ntsuas ntsuas raws li tus nqi tsis kam 1: Cov tswv yim tiv thaiv ≧ cov zis tsis kam> choj tsis kam 2: Nyob rau hauv ib txwm muaj, nruab nrab ntawm tus choj tsis kam yog tib yam lossis ob pawg yog tib yam (Ceebtoom: Cov tswv yim tiv thaiv yog qhov resistor nyob rau hauv nruab nrab ntawm EXC + rau EXC-, cov zis tsis kam yog qhov resistor nyob rau hauv nruab nrab ntawm SIG + rau SIG-, tus choj kuj yog cov kuj nyob rau hauv Qhov nruab nrab ntawm EXC + rau SIG +, EXC + rau SIG-, EXC- rau SIG +, EXC- rau SIG- Cov saum toj no yog txoj kev los txiav txim qhov zoo thiab qhov tsis zoo ntawm lub tshuab hnyav ntau hauv qhov hnyav. Nws tsis yooj yim rau kev puas tsuaj nyob rau hauv txhua qhov kev thov ib txwm muaj, ntau qhov kev ua txhaum yog tshwm sim los ntawm kev ua haujlwm tsis raug ntawm lub ntsuas lub cev, vim li ntawd, tag nrho cov txheej txheem ntawm kev ntsuas qhov system thov, disassembly thiab txij nkawm, nws yog ib qho tsim nyog. txhawm rau txo qhov kev sib tsoo thiab tsoo ntawm cov khoom dai, thiab ua tiav kev ua haujlwm tiag tiag raws li qhov hnyav ntawm cov tshuab thiab khoom siv. Tsib feem ntau cov hauv paus ntsiab lus ntawm multihead weighter bias Ces multihead weighter yuav inevitably ua rau kev tsis ncaj ncees nyob rau hauv daim ntawv thov, thiab dab tsi ntawm beas yuav multihead weighter? Dab tsi yog vim li cas rau qhov tsis sib xws? 1. Cov yam ntxwv sib txawv.

Ua los ntawm lub tshuab nws tus kheej, suav nrog DC drift qhov tseem ceeb, qhov ua yuam kev hauv qhov kev sib tw, lossis tsis yog-linearity hauv qhov ramp. Thaum kawg, yuav muaj qhov sib txawv ntawm qhov zoo tshaj plaws kev tsiv teb tsaws chaw thiab cov yam ntxwv tiag tiag ntawm lub tshuab. 2. Multihead weighter siv kev tsis ncaj ncees.

Qhov ntawd yog hais tias, qhov sib txawv tshwm sim los ntawm kev ua haujlwm tiag tiag, suav nrog kev tso qhov tsis raug ntawm qhov kev sojntsuam, kev rwb thaiv tsev tsis raug ntawm qhov kev sojntsuam thiab qhov chaw nyob ntsuas qhov tseeb, kev tu tsis raug ntawm cov pa roj lossis lwm yam vapors thaum lub sijhawm tu tag nrho, thiab qhov tsis raug ntawm cov ntse transmitters. Muaj ntau qhov sib txawv los ntawm kev ua haujlwm tsis raug, xws li kev tso chaw raug. 3. Dynamic sib txawv. Cov sensors uas siv cov qauv ntaub ntawv zoo li qub yog qhov kev vibration-damped heev thiab yog li qeeb los teb rau cov kev hloov pauv tseem ceeb hauv cov ntsiab lus tseem ceeb, txawm tias siv ob peb feeb los teb rau cov kauj ruam hloov hauv qhov kub thiab txias.

Qee lub taub hau hnyav nrog cov yam ntxwv latency tuaj yeem qhia qhov tsis ncaj ncees hauv kev teb rau kev hloov pauv sai. Teb ceev, amplitude dropout, thiab theem sib txawv dropout yog tag nrho cov ua rau dynamic deviations. 4. Insertion deviation.

Qhov no yog vim qhov sib txawv tshwm sim los ntawm qhov ntxig ntawm lub sensor hauv qhov system software, uas hloov qhov ntsuas qhov tseeb ntawm qhov tseem ceeb. Daim ntawv thov ntawm lub kaw lus mus rau lub tshuab xa hluav taws xob loj heev, cov yam ntxwv zoo ntawm lub kaw lus software qeeb dhau, thiab nws tus kheej cua sov hauv qhov system software loads lub zog ntau dhau, thiab lwm yam, txhua yam ua rau qhov sib txawv ntawm qhov nkag. 5, ib puag ncig ntuj sib txawv.

Kev siv ntau lub taub hau kuj tseem raug cuam tshuam rau ib puag ncig xws li kub, tshee, kev co, qhov siab, thiab kev sib xyaw evaporation, uas yog txhua yam yuav ua rau muaj kev sib txawv ntawm ib puag ncig ntuj.
