Taw qhia
Lub DXGE-30S geomagnetic dynamic simulation shielding system tuaj yeem ruaj khov thiab ua tau zoo tsim qhov sib npaug high-precision magnetic teb nyob rau hauv qhov opposite direction ntawm geomagnetic teb. Siv cov kev txiav-ntug high-precision fluxgate meter, kev tawm tswv yim ntawm lub sijhawm thiab kev hloov kho lub sijhawm tiag tiag.
Lub luag haujlwm tseem ceeb ntawm DXGE-30S system yog tshem tawm qhov hloov pauv ntawm thaj chaw geomagnetic hauv lub sijhawm. Los ntawm txoj haujlwm no, nws muaj peev xwm tsim kom muaj qhov zero sib nqus ib puag ncig nrog qhov tseeb txog li 10nT hauv qhov chaw geomagnetic. Qhov no txhais tau hais tias txawm nyob rau hauv ib puag ncig ntawm kev cuam tshuam geomagnetic muaj zog, nws tuaj yeem muab qhov chaw nyob ze ntawm qhov kev sim tsis muaj kev cuam tshuam rau cov kws tshawb fawb tshawb fawb.
Lub DXGE{{0}}S system kuj muaj qhov hloov tau zoo heev. Nyob rau hauv lub shielding chamber los yog shielding lub tog raj kheej, nws muaj peev xwm tsim 1nT los yog 0.1nT gradient magnetic teb, thiab txawm tsim ib qho chaw sib nqus chaw raws li kev sim. Tsis tas li ntawd, lub kaw lus tau raug qhuas rau nws cov kev ua tau zoo heev thiab ntau yam kev siv. Txawm hais tias nws yog nyob rau hauv aerospace teb, los yog nyob rau hauv tub rog thiab kev tshawb fawb cov tsev kawm ntawv xws li universities, nws plays ib tug indispensable luag hauj lwm. Nws cov high precision, stability thiab digital degree tau mus txog qib kev lag luam, thiab tau txais kev qhuas los ntawm cov neeg siv feem ntau.
Qhov system muaj pes tsawg leeg
Magnetic flux generating ntaus ntawv
1. Peb-dimensional coil qauv: Cov tub ntxhais ntawm lub tshuab hluav taws xob tsim hluav taws xob yog cov txheej txheem ntawm peb-dimensional coils tshwj xeeb tsim los tsim kom muaj qhov sib nqus sib nqus uas xav tau rau kev sim. Txhua qhov ntev muaj ib txheej ntawm cov coils uas ua kom muaj kev faib tawm ntawm cov hlau nplaum nyob rau hauv tag nrho peb cov lus qhia.
2. Lub zog tswj qhov system: Peb lub zog siv hluav taws xob sib raug zoo nrog peb-dimensional coil, thiab txhua lub zog hluav taws xob yog lub luag haujlwm rau kev tswj lub qhov ntev ntawm lub kauj.
3. High-precision fluxgate sojntsuam: Nyob rau hauv nruab nrab ntawm lub cuab yeej, ib tug high-precision inlet fluxgate sojntsuam yog muab tso rau. Qhov kev sojntsuam no ua raws li cov lus pom zoo rau kev tswjhwm kev sib nqus thiab tuaj yeem hnov txog kev hloov pauv hauv thaj chaw sib nqus hauv lub sijhawm.
4. Kev hloov kho lub khoos phis tawj sab saud: lub khoos phis tawj sab saud tau txais cov lus qhia tawm tswv yim los ntawm fluxgate sojntsuam, thiab kho cov nqi tam sim no ntawm cov khoom siv hluav taws xob siab los ntawm kev suav thiab kev tshuaj xyuas. Qhov kev tawm tswv yim kev hloov kho no ua kom muaj kev tiv thaiv kev tiv thaiv ntawm geomagnetic teb, ua rau lub cim ntawm cov hlau nplaum uas xav tau rau kev sim.
magnetic teb ntsuas ntaus ntawv
1. DX-330F fluxgate meter: Raws li cov ntsiab lus tseem ceeb ntawm cov khoom ntsuas magnetic, DX-330F fluxgate meter muaj qhov siab thiab ruaj khov.
2. Fluxgate sojntsuam: Siv ua ke nrog DX-330F fluxgate meter yog fluxgate sojntsuam, uas nyob rau hauv nruab nrab ntawm lub kauj thiab yog lub luag hauj lwm rau sensing lub magnetic teb zog nyob rau hauv ib tug uniform magnetic teb nyob rau hauv lub sij hawm. .
3. Real-time tawm tswv yim mechanism: Lub fluxgate sojntsuam yuav tawm tswv yim cov ntaub ntawv ntsuas magnetic teb rau DX-330F fluxgate meter nyob rau lub sijhawm, thiab tom qab ntawd muab cov ntaub ntawv raug siv rau kev hloov kho ntawm cov khoom siv hluav taws xob kom ntseeg tau tias magnetic teb raug thiab stability ntawm kev sim ib puag ncig.
