Tuam Tshoj yog lub teb chaws loj ntawm cov khoom siv hauv ntiaj teb tsis tshua muaj, tsis tshua muaj lub ntiaj teb cia yog thawj zaug hauv ntiaj teb, txawm tias nws yog SmCo series lossis NdFeB series tsis tshua muaj ntiaj teb cov khoom siv hlau nplaum ruaj khov tshawb nrhiav thiab kev tsim kho thiab daim ntawv thov muaj qhov zoo. Nrog rau kev txhim kho tas mus li ntawm qhov kev xav tau ntawm lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov, tswj cov hlau nplaum sib nqus M ntawm cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb thiab cov hlau nplaum poob qis θz ntawm lub ntsiab ncej yuav yog qhov tseem ceeb rau kev muab cov khoom sib nqus ruaj khov raws li cov khoom tseem ceeb. ntawm lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov raws li cov sensors.
Nws tuaj yeem ntsuas lub sijhawm sib nqus M ntawm axial magnetized tsis tshua muaj lub ntiaj teb cov khoom siv hlau nplaum ruaj khov thiab cov hlau nplaum poob qis Lub kaum sab xis θz ntawm lub ntsiab ncej, uas tuaj yeem muab kev lees paub zoo rau kev txhim kho tom qab ntawm cov sensors, feem ntau suav nrog cov teb ntawm lub xov tooj ntawm tes micro-motor hlau nplaum. , tsheb ceev sensor hlau nplaum, roj av tshawb hlau nplaum, Hall sensor hlau nplaum, thiab lwm yam.
Kev tsim cov hlau nplaum zoo yog ib txoj hauv kev rau cov lag luam kom muaj sia nyob thiab tsim cov txiaj ntsig siab. Tam sim no, cov neeg siv hauv tsev thiab txawv teb chaws tsis tsuas yog txhawj xeeb txog BH cov yam ntxwv ntawm cov khoom, tab sis kuj hais txog qhov sib xws ntawm lub sijhawm sib nqus ntawm cov khoom, thiab seb qhov sib nqus ntawm lub kaum sab xis ntawm lub ntsiab ncej yog tswj nyob rau hauv qhov kev tso cai. Qhov kev thov rau cov hlau nplaum zoo li no tseem yuav txhim kho nrog kev tsim cov khoom siv hluav taws xob ruaj khov hlau nplaum, thiab cov txiaj ntsig tau ntau dua li cov hlau nplaum zoo tib yam. Lub sijhawm sib nqus qhov ntsuas tau maj mam dhau los ua tus qauv ntsuas thoob ntiaj teb rau kev sib kis, thiab qhov sib ntxiv ntawm kev ntsuas kev sib nqus tau muaj qhov tseem ceeb heev rau kev sib nqus hlau hauv kev tshuaj xyuas kev taw qhia thiab txiav cov txheej txheem ntawm kev tsim khoom lag luam.
2. Kev tshawb fawb txog xwm txheej thiab kev txhim kho hauv tsev thiab txawv teb chaws
Kev ntsuas lub sij hawm sib nqus ib txwm siv thiab ntsuas cov khoom siv sib nqus sib nqus tuaj yeem rov qab mus rau xyoo 1990, thiab "vector magnetic moment test system" uas tsim los ntawm LDJ Company (kev sib koom ua ke los ntawm Laboratorio Elettrofisico) thiab cov khoom ntawm Brockhaus tuam txhab hauv lub teb chaws Yelemees tau tshaj tawm. Tom qab xyoo 2010, qhov zoo tshaj plaws yog qhov tshiab magnetic declination test system tsim los ntawm German matesy tuam txhab siv magnetoresistance matrix, thiab cov lag luam hauv tsev tseem siv cov txheej txheem coil.
Cov khoom siv ntsuas kev sib nqus ib txwm muaj yog tsim los ntawm kev siv fluxmeter thiab peb-dimensional Helmholtz coil, uas muaj lub hauv paus ntsiab lus yooj yim thiab muaj zog traceability. Txawm li cas los xij, vim tias qhov kev xav tau siab ntawm fluxmeter thiab ntsuas coil, qhov yuav tsum tau muaj ntawm fluxmeter drift tswj, Helmholtz coil calibration thiab coil orthogonal installation yog siab, thiab vim hais tias cov tsis-spindle tivthaiv sib nqus lub sij hawm tsawg heev, qhov kev daws teeb meem ntawm fluxmeter yog siab. . Cov no yog cov teeb meem uas yuav tsum tau daws kom ua tau ib txoj hauj lwm zoo nyob rau hauv ib txwm sib nqus declination test khoom. Nyob rau tib lub sijhawm, qhov yuav tsum tau ua rau qhov ntsuas ib puag ncig kuj tseem siab (qhov chaw sib nqus ib puag ncig tsis tuaj yeem hloov pauv).
