Tam sim no qhov xwm txheej ntawm kev txheeb xyuas cov qauv ntawm cov tshuab ua teb sib xyaw 1.1 Cov txheej txheem kev ntsuas kev ntsuas ib txwm siv hauv kev ntsuas ntsuas ntsuas ntawm fiber ntau raw cov ntaub ntawv xws li cov khoom siv hauv tsev, cov nplej. , roj, khoom noj, mining, thiab lwm yam, los yog thaum tswj cov seasonings hauv internet. . Cov khoom siv ntau dua yog: cov khoom siv hluav taws xob siv hluav taws xob, cov ntsuas dej ntws ntws tawm, cov ntsuas hluav taws xob nuclear, thiab cov ntsuas ntsuas lub log. Txoj kev ntsuas ntsuas no muaj nws tus yam ntxwv, tab sis cov kev txwv loj heev.

Kev siv thev naus laus zis ntawm kev siv hluav taws xob siv hluav taws xob tau qhia kom ntxaws, thiab cov kauj ruam yog raws li hauv qab no: Cov khoom siv hluav taws xob siv hluav taws xob sib txuas cov ntaub ntawv teeb liab thiab kev hloov pauv tus nqi (kev sib kis ceev piv) cov ntaub ntawv teeb liab ntawm tag nrho cheeb tsam ntawm kev lag luam. (them seem) kom tau txais tag nrho cov nqi ntws. Manipulable hom phiaj. Cov lus qhia ntxaws ntxaws ntawm kev ua cov thev naus laus zis ntawm cov khoom siv hluav taws xob ntsuas ntsuas: Tus nqi ntawm cov khoom siv raw yuav tsum tau rub tawm yog hloov raws li qhov sib piv ceev ntawm txoj siv rub-thiab-rub. Qhov loj me, lub nra ntawm txoj siv tsav yog txhua yam ruaj khov. Piv nrog rau lwm txoj kev pub mis, txoj kev no muaj txiaj ntsig zoo ntawm kev txheeb xyuas metrological thiab linearity.

Schematic daim duab ntawm kev ntsuas kev ntsuas ntsuas hluav taws xob ntawm cov khoom siv hluav taws xob ntsuas ntsuas: Kev pub noj thiab ntsuas kev ua haujlwm tau ua tiav ntawm ob txoj hlua sib kis raws li. 1.2 Txoj kev ntsuas kev ntsuas kev ntsuas teb yog siv nyob rau hauv lub tshuab sib xyaw ua ke. khoom siv, pob zeb ua teb tov khoom, bitumen rotary tov khoom. Raws li qhov tseeb ntawm kev txheeb xyuas metrological muaj kev txhawj xeeb, nyob rau theem no, cov cuab yeej zoo li no tsis tuaj yeem suav nrog kev sib tshuam. Yog li ntawd, txoj kev sib tov teb tsis nyiam los ntawm ntau tus neeg siv khoom, uas kuj yog ib qho laj thawj.

Kev ua qauv qhia kev tshawb fawb tuaj yeem qhia tau tias kev sib xyaw thiab kev ua tiav cov txheej txheem txiav txim siab los ntawm ob txoj kev ntsuas kev ntsuas no muaj lawv tus kheej qhov chaw siv tau, thiab kev siv cov sib tov sib xyaw yuav tsum tsis txhob cuam tshuam los ntawm kev txwv ib ntus. Nyob rau theem no, nyob rau hauv peb lub teb chaws, rotary mixing tshuab yog tag nrho cov ntsuas los ntawm ntim txoj kev los yog hluav taws xob siv scale / kauv scale. Nyob rau xyoo 1970s, kev sib xyaw ua haujlwm txuas ntxiv tau qhia los ntawm Tebchaws Europe los tsim thiab tsim. Txog tam sim no, tau zoo li no, thiab tseem tsis tau muaj kev txhim kho txij thaum pib mus txog thaum xaus. Qhov tseeb, ob txoj kev ntsuas kev ntsuas no tuaj yeem ua tiav siab precision hauv European daim ntawv thov. Piv txwv li, Schenck's kis tau tus mob batching scale nyob rau hauv Fabkis muaj ib tug dynamic seasoning raug ntawm 2%.

Tab sis nyob rau hauv kuv lub teb chaws, nws tsis zoo, vim hais tias nws nyob ntawm kev txwv ntawm kev lag luam hauv paus xws li tshuab thiab khoom tsim thiab cov khoom siv raw hauv kuv lub teb chaws. Nyob rau theem no, kev ntsuas thiab kev txheeb xyuas qhov tseeb ntawm cov khoom siv hluav taws xob siv hauv txoj kev hauv kuv lub teb chaws feem ntau tsuas yog kwv yees li 5%, uas tsis txawv ntawm qhov ntsuas qhov ntsuas qhov peev xwm, thiab kev ntseeg tau ntev ntev tsis muaj zog. ob. Tsis tu ncua ntsuas kev hloov pauv——Lub multihead weighter (Lus Askiv Loss-hauv-qhov hnyav) ntawm qhov sib txawv ntawm cov tshuaj txo qis (lub xeev tsis hnyav) tau siv thawj zaug hauv tag nrho cov txheej txheem ntawm kev tsim khoom hauv xyoo 1990 rau kev tshawb xyuas kev ntsuas ntsuas txuas ntxiv.

Multihead weighter maj mam hloov cov nplai siv hluav taws xob, cov nplais kauv, thiab txawm tias cov nplais sib xyaw. Raws li txoj kev ntsuas ntsuas tshiab thiab hloov kho tshiab, nws maj mam siv rau ntau thiab ntau cov ntaub ntawv raw. 2.1 Lub tswv yim tseem ceeb: Siv lub thoob qhov hnyav thiab lub koom haum pub noj raws li tag nrho lub cev lub cev, txuas ntxiv coj mus kuaj cov ntaub ntawv qhov hnyav ntawm lub ntsuas lub cev raws li qhov ntsuas vaj huam sib luag lossis software ntawm lub khoos phis tawj sab saud, thiab ntsuas qhov hloov pauv ntawm lub vas. hnyav nyob rau hauv chav tsev lub sij hawm raws li lub instantaneous ceev Tag nrho cov ntws, thiab ces technically daws raws li cov filtering technology ntawm ntau yam hardware thiab software, yuav siv tau raws li ib tug manipulation lub hom phiaj.“tshwj xeeb tag nrho ntws”.

Thaum lub hom phiaj tswj yog tag nrho cov dej ntws (t / h, kg / min), thiab cov khoom siv raw muaj kev thauj mus los zoo, thiab qhov ntsuas ntsuas ntsuas qhov ntsuas yuav tsum siab, lub xeev txoj kev hnyav tuaj yeem siv los ua cov phiaj xwm zoo tshaj plaws rau metrological. pov thawj.

2.2.2 Cov txheej txheem ntau lawm ntawm multihead weigher: Cov txheej txheem ntau lawm ntawm multihead weighter 2.2.3 Cov ntsiab lus uas yuav tsum tau them nyiaj rau hauv cov qauv tsim ntawm multihead weighter, yam uas cuam tshuam rau qhov precision: multihead weighter muaj cov yam ntxwv ntawm cov ntaub ntawv zoo li qub thiab cov nplai dynamic . Yog li ntawd, nyob rau hauv cov txheej txheem tsim System software, stipulate: 1. Qhov tsim nyog thauj tus nqi yog feem ntau 60% mus rau 70% ntawm cov nqi thauj mus los hauv kev ua haujlwm. Yog tias siv kev sib txuas lus thiab kev sib pauv hloov ceev, nws yog qhov zoo tshaj plaws los teb rau qhov kev ntxhov siab ntawm 35-40Hz. Qhov no ua kom muaj ntau yam kev hloov kho.

Nws kuj yog vim qhov kev ntseeg tsis zoo ntawm qhov system software thaum tus nqi thauj khoom tsawg dhau. 2. Kev ntsuas ntau ntawm lub sensor yog nruab nrab. Hauv lwm lo lus, lub sensor kuj siv 60% ~ 70% ntawm nws qhov ntsuas ntau raws li cov qauv. Cov ntaub ntawv teeb liab muaj ntau yam kev hloov pauv, uas yog qhov zoo heev los txhim kho qhov tseeb. 3. Cov txheej txheem tsim kho tshuab yuav tsum xyuas kom meej tias cov khoom siv raw muaj cov khoom zoo, thiab tseem xyuas kom meej tias lub sijhawm pub mis yog luv, thiab kev pub mis yuav tsum tsis txhob ntau dhau. Feem ntau, nws tau teev tseg tias kev pub mis yuav tsum tau ua txhua 5-10 feeb.

Cov cuab yeej kis tau tus mob ntawm cov chaw txhawb nqa yuav tsum ua kom ruaj khov thiab zoo linear zoo. 2.2.4 Daim ntawv thov kev cia siab: Nrog rau kev txhim kho sai ntawm kev tswj cov cuab yeej hluav taws xob, lub tshuab hluav taws xob ntau lub taub hau yog raws li kev xaiv cov thev naus laus zis tshiab, thiab qhov tseeb ntawm kev ntsuas ntsuas ntsuas tau nce los ntawm 0.3% mus rau 0.5%. Tus yuam sij rau cov thev naus laus zis tshiab no yog kev siv cov duab ntsuas qhov hnyav.

2.2.4.1 Daim ntawv thov ntawm cov zaub qhov hnyav sensor: Txhawm rau kom zoo dua ua ke rau hauv qhov tsim nyog ntawm kev ntsuas dynamic thiab raug, nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum tau siv los ua qhov system software key-in sensor hauv cov khoom hnyav. Tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas lub kaw lus yuav tsum tau ntse, cov ntaub ntawv tam sim los yog tsis ncaj qha ntawm lub sensor yog indispensable. Lub sijhawm no, qhov kev ntsuas tsis meej thiab qhov ntsuas qhov tseeb yog feem ntau yog ib khub ntawm qhov sib txawv, thiab nws yog ib qho nyuaj rau kev coj mus rau hauv tus account ob. Qhov xwm txheej tshwj xeeb raug xaiv los ua kev sib haum xeeb. Hauv kev lag luam hnyav, ntau cov tsoos digital analog sensors tau tsim thiab siv hauv kuv lub teb chaws nyob rau theem no, thiab cov zis ntawm cov teeb liab mem tes me me.

Noj ib qho hnyav sensor nrog ib tug loj tag nrho cov zis thiab lub hauv paus ntsiab lus ntawm resistor strain quab yuam raws li ib tug piv txwv, qhov loj loj tso zis yog 30-40mV. Yog li ntawd, cov ntaub ntawv teeb liab tau yooj yim cuam tshuam los ntawm lub xov tooj cua zaus, thiab kev sib kis ntawm cable kuj luv luv, feem ntau tsis pub dhau kaum meters. Nyob rau hauv lub thawv hnyav khoom (silo scale batching scale), kev pab cuam platform hnyav khoom los yog scale choj (electronic tsheb scale los yog rail scale) siv ob peb sensors nyob rau hauv series, cov ntaub ntawv system software yuav siv tau los ua kom tiav.“tus kheej calibration”.

Qhov no yog vim lub multi-channel digital sensor system software, tsis muaj teeb meem tsis sib haum. Cov neeg siv khoom nkag mus rau qhov chaw nyob kom ntxaws, qhov hnyav thiab rhiab heev ntawm txhua lub sensor, thiab qhov ntsuas tuaj yeem ua tiav.“plaub fab”los yog“ntug”Sib npaug, tsis tas yuav hloov kho tsab ntawv ib zaug ntxiv. Hauv kev simulation system, tom qab ob peb lub ntsuas hluav taws xob txuas ua ke, cov yam ntxwv ntawm txhua lub sensor tsis tuaj yeem txawv ntawm lwm tus. Thaum calibrating, tus qauv hnyav yuav tsum tau tso tawm ntawm txhua lub sensor thiab qhov voltage divider hauv lub davhlau ya nyob twg yuav tsum tau siv. Ua kev hloov kho.

Vim tias muaj kev sib tw t-test thaum kho, nws rov ua dua ob peb zaug. Nyob rau hauv cov ntaub ntawv system software, txhua tus neeg sensor raug tso cai los kuaj xyuas tus kheej. Yog li ntawd, lub sij hawm los kho tag nrho cov nqi ntawm qhov system software nrog digital sensor tsuas yog 1/4 ntawm qhov system simulation.

Nws tuaj yeem ua tiav siv cov ntaub ntawv system software“kuaj tus kheej”, uas yog, qhov kev kuaj mob ntws tsis tu ncua xyuas seb cov ntaub ntawv teeb liab ntawm txhua lub sensor puas raug txiav tawm, seb qhov tso zis ntau npaum li cas, thiab lwm yam. Yog tias muaj teeb meem, cov lus lossis lub tswb raug tso tawm ntawm lub dashboard lossis tswj vaj huam sib luag. , thiab cov neeg siv khoom tuaj yeem siv cov yuam sij ntawm lub vaj huam sib luag tswj kom pom txhua lub sensor, txheeb xyuas qhov ua rau ntawm qhov teeb meem ntawm tus kheej thiab ua kev daws teeb meem. Qhov kev txiav txim siab zoo no thiab kev ua haujlwm tsis raug tshem tawm yog pom tseeb qhov txiaj ntsig tseem ceeb rau cov neeg siv khoom, thiab nws nyuaj rau tsis nco qab thiab txo cov nqi hauv kev simulation ntawm analog sensor system software.

Hauv kev lag luam hnyav, qhov kev daws teeb meem ntawm kev hloov pauv coefficient SPWM ntawm qhov raug simulation sensor system software yog 16 khoom, thiab muaj 50,000 suav; thaum lub vijtsam daws teeb meem ntawm txhua lub sensor hauv cov ntaub ntawv system software yog 20 Bit, muaj 1,000,000 suav. Yog li, lub kaw lus software nrog 4 digital sensors tuaj yeem tsim qhov kev daws teeb meem ntawm 4,000,000 suav. Qhov zoo ntawm cov pixel siab no yog tshwj xeeb tshaj yog haum rau qhov chaw uas qhov hnyav ntawm lub nplai ncej loj heev thiab qhov hnyav ntawm cov khoom hnyav me me.

Piv txwv li: nyob rau hauv cov khoom hnyav hnyav, qee zaum qee yam ntawm cov khoom siv raw hauv daim ntawv qhia tsis pub leej twg paub tsuas yog tus lej me me xwb, tab sis qhov tseeb qhov yuav tsum tau muaj tseem siab heev. Qhov no kuj yog ib qho nyuaj ua kom tiav nyob rau hauv ib txwm system simulation. peb. Daim ntawv thov ntawm kev sib tov sib xyaw thiab qhov cuam tshuam ntawm kev lag luam kev cia siab Vim tias kev ntsuas thiab kev txheeb xyuas ntawm cov khoom siv teb hauv Suav teb tseem nyob hauv txoj kev ib txwm muaj, daim ntawv thov kev cia siab ntawm kev lag luam thiab kev txhawb nqa ntawm multihead weighter yuav yog qhov dav heev. , Cov txheej txheem sib xyaw txuas ntxiv ntawm bitumen muaj qhov hloov pauv hloov pauv, thiab kev tswj xyuas meej ntawm tag nrho cov dej ntws tuaj yeem tsim cov khoom sib tov zoo heev.

Vim tias cov khoom sib tov teb muaj cov qauv yooj yim thiab cov nqi kho mob tsawg, ib zaug cov khoom sib tov sib xyaw yog tswj nruj, nws yuav hloov qhov xwm txheej tam sim no ntawm kev lag luam qis ntawm cov khoom sib tov. Hauv particular, cov tshuab tsim-ntaus thiab cov khoom siv uas yuav tsum tau muaj nyob rau hauv txoj kev thiab kev siv hluav taws xob engineering muaj qhov tseem ceeb, thiab cov khoom siv ntau lub taub hau yog qhov kev txhim kho tseem ceeb los txhim kho qhov tseeb ntawm kev txheeb xyuas metrological.
