KhoomDsau ntawv
GSEM-W10 yog IoT-enabled broadband magnetotelluric system tsim los ntawm ntau tshaj li ob xyoo caum ntawm kev tshawb fawb coj los ntawm Associate Professor Chen Rujun los ntawm Lub Tsev Kawm Ntawv ntawm Geosciences thiab Info-Physics, Central South University. Tsim los rau ib puag ncig nrog cov suab nrov nrov electromagnetic, lub kaw lus tuaj yeem lees paub, cais, thiab cuam tshuam ze ntawm - teb cuam tshuam, tso cai kom ruaj khov ntawm MT impedance cov ntaub ntawv txawm tias muaj kev cuam tshuam hnyav heev.
Raws li cov cuab yeej tshawb fawb geophysical tag nrho, GSEM-W10 ua ke AMT thiab MT / LMT hom hauv ib lub teeb yuag thiab qis - lub zog platform. Nws txhawb nqa loj - nplai IoT kev sib txuas ntawm ntau pua lub cuab yeej, ua kom cov ntaub ntawv tshawb fawb raug thaum txo cov nqi ua haujlwm. AMT hom ua tiav qhov kev tshawb nrhiav qhov tob ntawm ib ncig ntawm 1,000 m, thaum MT hom nce mus txog 150 km, ua tau raws li qhov xav tau kev tshawb nrhiav tob thiab tob.

Cov Cai Ua Haujlwm
Lub kaw lus sau cov khoom siv hluav taws xob zoo li qub hauv cov lus qhia orthogonal rau infer subsurface resistivity qauv. Vim tias ntuj EM cov cim tsis muaj zog thiab cuam tshuam yooj yim, GSEM-W10 cov cuab yeej tshawb fawb geophysical siv cov qauv tsim hluav taws xob siab tshaj, kev lim dej digital, thiab wireless synchronization technologies los txhim kho cov ntaub ntawv ruaj ntseg. Ua ke nrog GSEM-PROS ua software- tau tsim ua ke nrog MT cov kws tshaj lij cov ntaub ntawv los ntawm Lavxias Academy ntawm Kev Tshawb Fawb- cov neeg siv tuaj yeem tau txais impedance nkhaus thiab zoo- tswj cov khoom tawm sai, txawm tias cov khoom xa tawm loj.
Cov yam ntxwv tseem ceeb
Txhua theem ntawm cov analog pem hauv ntej- kawg yog tsim los khaws cov teeb liab kom pom tseeb-los ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov tseeb calibration mus rau txheej lim. Qhov kev tsim no ua kom lub suab nrov hauv pem teb nyob rau theem qis, kom ntseeg tau tias qhov kev hloov pauv ntawm EM tsis muaj zog tau raug ntes nrog kev cuam tshuam tsawg.
Ib qho kev hloov kho ARM suav nrog cov tub ntxhais kawm thiab cov qauv Linux tsim ua kom lub cev muaj zog kos qis dua cov cuab yeej MT. Cov pab pawg ua haujlwm tuaj yeem tso siab rau lub txhab nyiaj hluav taws xob tus qauv rau ib hnub ua haujlwm tag nrho, txo cov roj teeb logistics thiab ua kom yooj yim rau kev thauj mus los ntev -.
GSEM-W10 cov cuab yeej tshawb fawb geophysical hais txog kev cuam tshuam los ntawm ntau cov lus qhia ib zaug. Cov ntxaij lim dej kho vajtse txo cov neeg kho tshuab thiab cov suab nrov, thaum hloov kho thiab tshuab -kev kawm algorithms cia li cais thiab txwv tus txiv neej muaj zog- ua cov cim. Thaum ntau chav nyob raug xa mus ua ib lub wireless array, synchronized acquisitions ntxiv dag zog rau tus ntoo khaub lig-chaw nres tsheb correlation, ntxiv thawb down uncorrelated suab nrov.
Parallel multi-band acquisition shortens txhua lub chaw nres tsheb lub sijhawm kaw, ua kom muaj txiaj ntsig zoo ntawm cov ntawv ntev ntev lossis cov khoom ntom ntom. Kev tswj hwm wireless ntawm Wi-Fi thiab ZigBee tso cai rau ib tus neeg teb xov tooj los teeb tsa thiab saib xyuas txhua chav nyob ntawm qhov deb, thiab cov software ua haujlwm ntau -tus qauv tsim txiav impedance xam lub sij hawm mus rau ib feem me me ntawm cov pa ua haujlwm.
Cov txheej txheem PCB ntau- txheej txheej thiab cov vaj tsev zoo tshaj plaws txo cov ntsuas ntsuas tag nrho. Txij li thaum lub kaw lus lees txais cov tsev txhab nyiaj hluav taws xob sab nraud, kev thauj mus los yooj yim thiab kev mus los hauv huab cua yuav yooj yim dua yam tsis muaj cov roj teeb tshwj xeeb.
Daim ntawv thov
Rau cov neeg siv khoom hauv kev tshawb nrhiav ntxhia, kev tshawb fawb txog hluav taws xob, kev ntsuam xyuas engineering, lossis kev tshawb fawb hauv av, GSEM-W10 cov cuab yeej tshawb fawb geophysical muab ib txoj hauv kev los khaws cov ntaub ntawv subsurface tseem ceeb txawm nyob hauv qhov chaw uas muaj suab nrov hluav taws xob feem ntau yog ib qho teeb meem. Cov tuam txhab mining tuaj yeem siv nws los ua daim ntawv qhia zais orebodies hauv qab npog lossis hauv thaj chaw ua haujlwm nyuaj. Cov pab pawg muaj zog tau txais txiaj ntsig los ntawm nws qhov tob tob thaum ntsuas lub hauv paus architecture lossis kev ua txhaum. Cov neeg siv engineering thiab ib puag ncig tau txais cov cuab yeej siv tau los nrhiav cov chaw tsis muaj zog, kab noj hniav, lossis cov dej ntws tsis muaj kev thauj mus los hnyav. Vim tias lub kaw lus txhawb nqa IoT kev sib txuas lus thiab kev xa tawm yooj yim, cov haujlwm tshawb fawb tuaj yeem ua tiav nrog cov neeg ua haujlwm me me, lub sijhawm nruj dua, thiab txo cov nqi khiav haujlwm-txhua yam thaum tswj cov ntaub ntawv zoo ib yam.
Case Study: AMT Survey in Zhugongtang, Guizhou
Hauv kev tshawb fawb ntawm Zhugongtang loj hlau lead-zinc deposit, 1,280 m AMT profile nrog 61 chaw nres tsheb (20 m sib nrug, 1-10,400 Hz) tau ua tiav siv GSEM-W10 geophysical ntsuam xyuas ntsuas. Qhov kawg resistivity seem qhia meej qhia cov gradient zones thiab ib tug tsawg-resistivity feature uas cim tau zoo mineralization. Cov anomalies no sib raug zoo nrog cov paub orebody geometry thiab qhov chaw, paub meej tias GSEM -W10 geophysical ntsuam xyuas cov cuab yeej tuaj yeem daws cov yam ntxwv tseem ceeb thiab lithological uas yuav tsum tau muaj hauv kev tshawb fawb pob zeb hauv metallic.
