Niaj hnub no, cov tshuab sib tov rotary hauv peb lub teb chaws siv txoj kev muaj peev xwm lossis qhov ntsuas siv hluav taws xob / qhov ntsuas kauv. Ob hom kev ntsuas thiab kev txheeb xyuas tau siv. Kev tsim kho tshiab ntawm cov txheej txheem sib tov rotary tau qhia los ntawm Tebchaws Europe hauv xyoo 1970. Tsis muaj kev txhim kho txij thaum pib mus txog thaum kawg. Qhov tseeb, ob txoj kev tuaj yeem ua tiav qhov tseeb siab hauv Tebchaws Europe. Piv txwv li, Schenck's transmission belt batching scale hauv Fabkis muaj qhov tseeb batching dynamic ntawm 2%. Tab sis nws tsis zoo hauv kuv lub teb chaws, qhov laj thawj nyob ntawm qhov kev txwv ntawm cov khoom siv xws li kev lag luam ua tshuab thiab cov khoom siv raw hauv kuv lub teb chaws.

Niaj hnub no, qhov ntsuas qhov tseeb ntawm cov nplai siv hluav taws xob hauv kuv lub teb chaws txoj kev feem ntau tsuas yog li 5% xwb, uas tsis deb ntawm qhov kev txheeb xyuas qhov ntsuas raws li lub peev xwm, thiab qhov kev ntseeg siab mus sij hawm ntev tsis zoo. Ntu 2: Kev Tsim Kho Tshiab hauv Kev Ntsuas Qhov Hnyav tas mus li - Cov Teeb Meem Sib Txawv (Lub Xeev Tsis Muaj Hnyav) Cov Nplai. Txij li xyoo 1990, ntau lub taub hau weigher (Lus Askiv Poob-hauv-qhov hnyav) tau siv tas mus li hauv kev tsim khoom lag luam.

Cov nplai siv hluav taws xob, cov nplai kauv, cov nplai sib sau ua ke, thiab lwm yam maj mam hloov lub tshuab ntsuas ntau lub taub hau. Raws li txoj kev txheeb xyuas kev ntsuas tshiab thiab hloov kho tshiab, ntau thiab ntau cov khoom siv raw khoom raug xaiv. 2.1 Tus qauv yooj yim: Siv lub thoob ntsuas kev txheeb xyuas qhov ntsuas thiab lub koom haum pub mis tag nrho, txuas ntxiv kuaj cov ntaub ntawv txheeb xyuas qhov ntsuas raws li lub vaj huam sib luag lossis software computer sab saud, thiab xam cov coefficient elastic ntawm kev txheeb xyuas qhov ntsuas ib lub sijhawm ua qhov ntws tag nrho tam sim ntawd, thiab tom qab ntawd raws li ntau yam software thiab kho vajtse teeb tsa ntawm cov lim dej tau daws teeb meem kom tau txais "kev ntws tag nrho tshwj xeeb". Kev ntsuas qhov tseeb ntawm cov dej ntws yog qhov tseem ceeb heev, nws yog lub hauv paus rau kev ntsuas qhov tseeb ntawm lub tshuab ntsuas ntau lub taub hau.

Daim duab no suav nrog ib txoj kev qub: Thaum kawg, raws li PID feedback optimization algorithm, FC ua haujlwm tiag tiag ntawm kev tswj ze rau tag nrho cov dej ntws, thiab tso tawm cov ntaub ntawv kho kom raug los tswj lub soft starter thiab lwm cov laug cam tswj kev pub mis. 2.2 Siv cov ntsuas qhov sib txawv ntawm cov teeb liab (multihead weigher) hauv cov pob zeb: Nws tuaj yeem pom los ntawm lub hauv paus ntsiab lus tias nws yuav tsis raug mob los ntawm kev hloov pauv khoom siv kho tshuab ntawm qhov ntsuas thiab lub koom haum pub mis, nws tsuas yog ntsuas qhov sib txawv ntawm qhov hnyav (qhov sib txawv ntawm qhov hnyav), thiab Cov txiaj ntsig ntawm cov txheej txheem ntsuas dynamic ib txwm paub zoo. Nyob rau hauv qhov xwm txheej uas lub hom phiaj tswj yog tag nrho cov dej ntws (t / h, kg / min), yog tias lub peev xwm thauj khoom siv raw thiab qhov tseeb ntawm kev txheeb xyuas metrological yog qhov siab, txoj kev tsis muaj qhov hnyav tuaj yeem siv ua txoj kev npaj zoo tshaj plaws rau kev txheeb xyuas metrological.

2.2.2 Cov txheej txheem tsim khoom ntawm lub tshuab ntsuas ntau lub taub hau: 2.2.3 Cov qauv tsim ntawm lub tshuab ntsuas ntau lub taub hau yuav tsum tau them sai sai rau cov yam ntxwv uas ua rau muaj kev phom sij rau qhov ntsuas qhov tseeb: lub tshuab ntsuas ntau lub taub hau coj mus rau hauv tus account cov yam ntxwv ntawm cov ntaub ntawv zoo li qub thiab cov nplai dynamic. Yog li ntawd, hauv kev tsim qauv ntawm lub kaw lus tswj hwm, nws tau teev tseg: 1. Qhov ntau thiab tsawg ntawm kev thauj mus los, feem ntau, qhov ntau thiab tsawg ntawm kev ua haujlwm tshwj xeeb yog 60% txog 70% ntawm qhov muaj peev xwm thauj khoom. Thaum siv kev sib txuas lus thiab kev hloov pauv ceev, qhov zaus ntawm kev ntxhov siab yog 35-40HZ. Ntau yam kev hloov kho tau lees paub.

Tsis tas li ntawd vim tias qhov ceev thauj khoom qis dhau, qhov kev ntseeg tau ntawm lub kaw lus software tsis muaj zog. Qhov thib ob, kev xaiv ntawm qhov ntau ntawm sensor thiab cov mis xam yog qhov tsim nyog. Uas yog hais tias, lub sensor kuj siv 60% ~ 70% ntawm nws qhov ntsuas ntau, thiab qhov ntau ntawm cov teeb liab hloov pauv yog dav, uas yog qhov zoo heev rau kev txhim kho qhov tseeb.

3. Lub tshuab tsim qauv kom ntseeg tau tias cov khoom siv raw tau yooj yim, thiab kom ntseeg tau tias lub sijhawm pub mis luv luv thiab tsis pub mis ntau zaus. Feem ntau, pub mis ib zaug txhua 5-10 feeb. Cov kev sib kis pabcuam yuav tsum du thiab ncaj. 2.2.4 Daim ntawv thov tseem ceeb: Nrog rau kev txhim kho sai ntawm kev siv tshuab tswj lub cev muaj zog, lub tshuab ntsuas ntau lub taub hau siv cov thev naus laus zis tshiab, thiab nws qhov kev ntsuas raug sib txawv ntawm 0.3% txog 0.5%.

Qhov tseem ceeb rau cov thev naus laus zis no yog kev siv cov ntaub ntawv ntsuas qhov hnyav, uas tuaj yeem ua rau qhov hnyav ntawm qhov hnyav sensor 0.1% ~ 0.2% lossis siab dua. 2.2.4.1 Kev siv cov ntaub ntawv ntsuas qhov hnyav sensor: Yuav kom xav txog qhov tsim nyog ntawm kev ntsuas dynamic thiab raug, nws yog ib qho tseem ceeb heev uas yuav tsum xaiv lub sensor ntawm qhov kawg ntawm qhov system software. Tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas lub kaw lus yuav tsum ntse, tus lej tam sim ntawd lossis tsis ncaj qha ntawm lub sensor zoo li tseem ceeb heev. Lub sijhawm no, qhov tsis paub meej ntawm kev ntsuas thiab qhov ntsuas qhov tseeb feem ntau yog ob qho sib txawv, thiab ob qho tsis tuaj yeem ua ke. cov cuab yeej, tab sis yuav tsum tau ntsuas ntawm ib rooj plaub-rau-ib rooj plaub.

Nyob rau theem no, ntau lub ntsuas digital thiab analog ib txwm siv hauv kev lag luam hnyav hauv Suav teb, thiab lub teeb liab pulse tshwm sim tsis loj. Piv txwv li, lub hauv paus ntsiab lus ntawm lub zog resistor siv los tsim lub ntsuas qhov hnyav nrog cov zis loj, thiab nws cov zis feem ntau yog 30-40 mV. Yog li ntawd, nws cov teeb liab cov ntaub ntawv raug cuam tshuam los ntawm kev cuam tshuam ntawm lub xov tooj cua zaus, thiab qhov deb ntawm lub cable kuj luv heev, feem ntau hauv 10 meters.

Xaiv ntau lub sensor series lub nkoj hnyav software (silo weighing scale), kev pabcuam platform weighing system software lossis qhov sib npaug ntawm qhov hnyav choj (electronic truck scale lossis rail scale), cov ntaub ntawv system software tuaj yeem ua tiav "tus nqi tshaj tawm tus kheej". Vim yog ntau-channel digital sensor system software, tsis muaj teeb meem sib phim resistor. Tus neeg siv tuaj yeem nkag mus rau qhov chaw nyob ntawm tus sensor, qhov hnyav thiab qhov rhiab heev ntawm qhov ntsuas, thiab qhov ntsuas tuaj yeem ua tiav tau. "plaub lub ces kaum" lossis "ntug" Qhov sib npaug ntawm cov ntawv Askiv tsis tas yuav hloov kho ntau zaus.

Thaum muaj ntau lub sensors txuas nrog lub software simulation system, cov yam ntxwv ntawm txhua lub sensor tsis tuaj yeem txheeb xyuas tau zoo, thiab txhua lub sensor yuav tsum tau calibrated thiab txhua lub sensor yuav tsum tau calibrated siv lub voltage divider hauv lub terminal block. Lub cuab yeej raug calibrated. Vim tias muaj kev sim t paired hauv tag nrho cov txheej txheem ntawm kev hloov kho, nws rov ua dua ntau zaus. Rau cov software system data, tso cai rau kev txheeb xyuas ywj pheej ntawm txhua tus ua ib lub sensor.

Yog li ntawd, lub sijhawm siv los kho qhov software ntawm lub sensor ntse tsuas yog 1/4 ntawm qhov kev sim ua qauv ntawm lub system. Lub software ntawm lub system tuaj yeem "kuaj xyuas tus kheej", uas yog, cov txheej txheem kuaj mob tuaj yeem kuaj xyuas tas li seb cov ntaub ntawv teeb liab ntawm txhua lub sensor puas raug kaw, seb cov zis puas ntau dhau, thiab lwm yam. Yog tias muaj qhov yuam kev tshwm sim, cov ntaub ntawv lossis lub tswb ceeb toom yuav raug tso tawm rau ntawm lub vaj huam sib luag lossis lub vaj huam sib luag ua haujlwm. Cov neeg siv khoom tuaj yeem siv cov yuam sij ua haujlwm ntawm lub vaj huam sib luag tswj hwm los tshawb nrhiav txhua lub sensor, txheeb xyuas qhov ua rau muaj qhov yuam kev thiab tshem tawm qhov yuam kev.

Lub peev xwm los kuaj pom thiab tshem tawm cov teeb meem feem ntau yog qhov tseem ceeb rau cov neeg siv khoom, thiab hauv kev simulation ntawm analog sensor system software, cov txiaj ntsig zoo li no yog qhov tsim nyog heev rau kev ua qauv. Ib txwm simulation sensor system software Hauv kev lag luam hnyav, qhov kev daws teeb meem ntawm lub vijtsam ntawm lub analog-rau-digital converter yog 16 bits, thiab muaj 50,000 suav muaj; thiab qhov kev daws teeb meem ntawm txhua lub sensor hauv cov ntaub ntawv software yog 16 bits. Nrog 20 bits, muaj 1,000,000 suav muaj. Yog li, lub kaw lus software nrog 4 lub digital sensors tuaj yeem tsim 4,000,000 suav kev daws teeb meem ntawm lub vijtsam.

Nws yog ib qho zoo ntawm cov pixels siab, tshwj xeeb tshaj yog thaum qhov hnyav ntawm lub thav duab nws tus kheej hnyav thiab qhov hnyav me me. Piv txwv li, hauv cov software system weighing batch, qee zaum qee cov khoom siv raw tsuas yog ib feem me me ntawm daim ntawv qhia zais cia, tab sis qhov yuav tsum tau ua kom raug tseem siab heev. Cov xwm txheej zoo li no nyuaj rau ua tiav hauv kev ua qauv ib txwm muaj.

2.3 Cov xwm txheej ntawm daim ntawv thov hauv tsev thiab txawv teb chaws (tau txais hauv cov nroj tsuag tshuaj, kev lag luam hlau, yas, tshuaj fiber, thiab lwm yam) Hauv ntau qhov chaw, muaj kev paub ua haujlwm hauv kev siv lub tshuab ntsuas ntau lub taub hau. Piv txwv li: cov khoom siv ua kom zoo nkauj. Nyob rau xyoo tas los no, nws tau siv dav hauv ntau qhov chaw xws li cov khoom siv roj hmab, cov tshuaj fiber, thiab cov khoom siv kho qhov muag.

Hauv qee qhov kev lag luam tsim khoom, qhov kev ntsuas qhov hnyav tsis tu ncua tuaj yeem ua kom muaj kev sib xyaw ua ke ntawm cov ntaub ntawv blanking, thiab qhov sib tov yuav tsum tsis muaj zog, uas ua rau cov txheej txheem ua haujlwm yooj yim dua. Cov khoom no tiav heev txawv teb chaws. Piv txwv li, Fabkis Schenck Enterprise, Buda Benla Enterprise, thiab Fabkis Pioneer Enterprise, thiab lwm yam, lawv cov thev naus laus zis yuav ua rau lub ntiaj teb thoob ntiaj teb. Ntawm lawv, cov tub rog siv cov thev naus laus zis digital sensor, thiab qhov tseeb dynamic ncav cuag 0.25%.

Qhov tseeb ntawm qhov ntsuas qhov sib npaug ntawm cov ntaub ntawv zoo li qub tau ua tiav hauv tag nrho cov txheej txheem ntawm kev tsim khoom lag luam. Siv rau hauv cov khoom sib tov rotary thiab cov teeb meem yav tom ntej. Hauv kev ntsuas kev ua haujlwm ntawm cov tshuab sib tov tas mus li hauv kuv lub tebchaws, nws tseem nyob ntawm txoj kev ntsuas kev ntsuas ib txwm muaj. Yog li ntawd, daim ntawv thov thiab kev txhawb nqa ntawm ntau lub taub hau weigher yog qhov tseem ceeb heev rau cov txheej txheem ua tiav ntawm cov cement stabilized av sib tov, cov pob zeb sib tov tas mus li, thiab asphalt sib tov tas mus li. Nws kuj muaj qhov tseem ceeb heev rau kev tswj hwm qhov tseeb ntawm tag nrho cov dej ntws.

Vim yog qhov yooj yim ntawm cov txheej txheem sib xyaw ua ke thiab tus nqi kho qis, thaum cov khoom sib xyaw sib xyaw zoo dua, qhov kev lag luam qis tam sim no ntawm kev sib xyaw ua ke yuav hloov pauv. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho txoj kev thiab hydropower, qhov twg cov kev cai siab tau muab rau cov tshuab ua kom ntau lawm, lub tshuab ntsuas ntau lub taub hau yog ib kauj ruam tseem ceeb hauv kev ua kom qhov tseeb ntawm kev txheeb xyuas metrological.
