Taw qhia
Radar qib sensors tau dav siv hauv kev lag luam siv rau kev ntsuas qhov tseeb thiab txhim khu kev qha ntawm cov kua thiab cov khib nyiab. Piv nrog rau cov cuab yeej ntsuas kev sib cuag ib txwm muaj, radar qib sensors tuaj yeem muab tsis yog - ntsuas kev sib cuag, tiv taus plua plav, vapor, kub hloov pauv, thiab qhov chaw hnyav.
Txawm li cas los xij, calibration kom raug yog qhov tseem ceeb los xyuas kom meej qhov ntsuas qhov tseeb thiab kev ua haujlwm ruaj khov. Kev teeb tsa tsis raug lossis kev teeb tsa tsis raug tuaj yeem ua rau kev nyeem tsis raug, teeb liab poob, lossis tsis muaj suab nrov.
Phau ntawv qhia no piav qhia txog yuav ua li cas ntsuas lub ntsuas ntsuas radar, suav nrog kev npaj, ntsuas qhov ntsuas, thiab cov lus qhia daws teeb meem.
Vim li cas Radar Level Sensor Calibration tseem ceeb?
Radar qib sensors ntsuas qhov kev ncua deb ntawm lub sensor thiab cov khoom nto los ntawm kev xa cov teeb liab microwave thiab tau txais cov suab nrov. Lub sensor xam cov qib raws li lub tank qhov siab thiab ntsuas qhov ntsuas. Kev calibration kom zoo yuav pab tau:
- Txhim kho qhov ntsuas qhov tseeb
- Tshem tawm cov cim qhia tsis tseeb
- Hloov lub sensor mus rau lub tank sib txawv
- Xyuas kom ruaj khov ua haujlwm nyob rau hauv ib puag ncig nyuaj
- Txo kev tu thiab kho lub sijhawm
Rau niaj hnub80GHz FMCW radar qib sensors, feem ntau calibration cov kauj ruam yuav ua kom tiav los ntawm software, tso saib modules, los yog kev sib txuas lus interfaces tsis muaj kev kho tshuab.
Ua ntej Calibrating Radar Qib Sensor

2. Tshawb xyuas Cov Ntawv Thov Kev Siv Yooj Yim
Sau cov ntaub ntawv hauv qab no ua ntej configuration:
- Kev ntsuas ntau
- Tank qhov siab
- Qhov nrug deb
- Qib siab kawg thiab yam tsawg kawg nkaus
- Hom nruab nrab (kua, hmoov, nplej, thiab lwm yam)
- Dielectric qhov tsis tu ncua ntawm cov khoom
- Txheej txheem kub thiab siab
Cov kev txwv no pab lub radar sensor kom raug txheeb xyuas lub hom phiaj xav tau.
Kauj ruam-los ntawm-Radar Level Sensor Calibration Procedure
Kauj Ruam 1: Teem Kev Ntsuas Qhov Ntsuas.
Kauj Ruam 2: Kho qhov nrug deb thiab tag nrho nrug
Kauj ruam 3: Xaiv qhov Kho Nruab Nrab Hom thiab Parameters
Kauj ruam 4: Ua False Echo Mapping
Kauj Ruam 5: Tshawb xyuas Echo Signal thiab Fine-Tune Parameters
Nco tseg: ntau hom radars yuav txawv. Ua raws li cov neeg siv phau ntawv ntawm cov chaw tsim khoom.
