Masensa oyezera nthaka okhala ndi mphamvu ndi njira imodzi yodziwika bwino poyesa chinyezi cha nthaka masiku ano (nthawi zambiri amakhala a mtundu wa frequency-domain reflectometry (FDR)). Mfundo yaikulu ndikupeza chinyezi cha volumetric m'nthaka mwa kuyeza chokhazikika chake cha dielectric. Popeza chokhazikika cha dielectric cha madzi (pafupifupi 80) ndi chachikulu kwambiri kuposa cha zigawo zina m'nthaka (pafupifupi 1 ya mpweya ndi pafupifupi 3-5 ya matrix ya nthaka), kusintha konse kwa chokhazikika cha dielectric cha nthaka kumadalira kwambiri chinyezi.
Izi ndi zinthu zake zazikulu:
I. Mphamvu ndi Ubwino Wapakati
1. Mtengo wotsika komanso wosavuta kutchuka
Poyerekeza ndi masensa owunikira nthawi (TDR) omwe ali ndi mphamvu zambiri, masensa owunikira ali ndi zida zamagetsi zochepa komanso ndalama zochepa zopangira, zomwe zimathandiza kuti agwiritsidwe ntchito kwambiri pazochitika zomwe zimafuna kuyikidwa kwakukulu, monga ulimi wanzeru ndi ulimi wothirira m'munda.
2. Kugwiritsa ntchito mphamvu zochepa kwambiri
Ma circuit oyezera mphamvu okha amagwiritsa ntchito mphamvu zochepa kwambiri ndipo ndi oyenera kwambiri kuyang'anira malo kwa nthawi yayitali komanso kugwiritsa ntchito intaneti ya zinthu pogwiritsa ntchito mabatire ndi ma solar panels. Amatha kugwira ntchito mosalekeza kwa miyezi kapena zaka.
3. Ikhoza kuyang'aniridwa mosalekeza kwa nthawi yayitali
Poyerekeza ndi njira yowumitsa yomwe imafuna kugwiritsidwa ntchito ndi manja, masensa otha kuyikamo zinthu amatha kuikidwa m'nthaka kuti asonkhanitse deta mosayang'aniridwa, mosalekeza komanso modzidzimutsa, ndipo amatha kujambula kusintha kwa chinyezi cha nthaka, monga momwe kuthirira, mvula ndi kuuma kwa nthaka.
4. Kukula kwake ndi kochepa komanso kosavuta kuyika
Masensa nthawi zambiri amapangidwa ngati ma probe. Ingobowolani dzenje pamalo oyezera ndikuyika probe molunjika m'nthaka, zomwe sizingawononge kwambiri kapangidwe ka nthaka.
5. Kukhazikika kwabwino komanso kulibe mphamvu ya radioactive
Mosiyana ndi ma neutron mita, ma capacitive sensor sagwiritsa ntchito magwero aliwonse a radioactive, ndi otetezeka kugwiritsa ntchito, ndipo safuna chilolezo chapadera kapena chitetezo.
6. Yogwirizana komanso yanzeru
N'zosavuta kwambiri kuphatikiza ndi osonkhanitsa deta ndi ma module otumizira opanda zingwe (monga 4G/LoRa/NB-IoT) kuti apange netiweki yonse yowunikira chinyezi cha nthaka. Ogwiritsa ntchito amatha kuwona detayo patali nthawi yeniyeni kudzera pa mafoni am'manja kapena makompyuta.
Ii. Zolepheretsa ndi Zovuta
Kulondola kwa muyeso kumakhudzidwa ndi zinthu zingapo
Kapangidwe ka nthaka: Ma curve a calibration a dongo, loam ndi dothi lamchenga ndi osiyana. Masensa nthawi zambiri amayesedwa ndi mchenga wamba ndi dothi akamachoka ku fakitale. Kugwiritsa ntchito mwachindunji m'nthaka yamitundu yosiyanasiyana kungayambitse zolakwika.
Mphamvu ya magetsi oyendetsera nthaka (mchere): Ichi ndi chimodzi mwa zinthu zazikulu zomwe zimapangitsa kuti masensa oyezera magetsi azilephera kugwira ntchito. Ma ayoni amchere m'nthaka amatha kusokoneza minda yamagetsi, zomwe zimapangitsa kuti miyeso ikhale yokwera. Mu nthaka yokhala ndi mchere, kulondola kwa muyeso kumachepa kwambiri.
Kukhuthala kwa nthaka ndi kufooka kwa nthaka: Kaya choyezeracho chili pafupi ndi nthaka komanso ngati pali ma pores akuluakulu kapena miyala m'nthaka, zonsezi zidzakhudza kulondola kwa zotsatira za muyeso.
Mphamvu ya kutentha: Kusintha kwa dielectric nthawi zonse kumasintha ndi kutentha. Masensa apamwamba kwambiri ali ndi masensa a kutentha omwe amamangidwa mkati kuti abwezeredwe, koma mphamvu ya chiwongola dzanja ndi yochepa.
2. Kuyesa pamalopo ndikofunikira
Kuti mupeze zotsatira zolondola kwambiri, makamaka m'mitundu inayake ya nthaka, nthawi zambiri pamafunika kuyeza pamalopo. Izi zikutanthauza kuti, zitsanzo za nthaka zimasonkhanitsidwa, kuchuluka kwa chinyezi kumayesedwa pogwiritsa ntchito njira yokhazikika yowumitsa, kenako nkuyerekeza ndi mawerengedwe a sensa kuti pakhale equation yowunikira komweko. Iyi ndi sitepe yofunika kwambiri kuti zitsimikizire kulondola kwa deta, komanso kumawonjezera mtengo wogwiritsira ntchito komanso malire aukadaulo.
3. Muyeso wa malo oyezera ndi wapafupi
Mulingo woyezera wa sensa umangokhala pa kuchuluka kwa nthaka yozungulira probe (monga, "dera lodziwika bwino" la sensa). Derali nthawi zambiri limakhala laling'ono kwambiri (makiyubiki masentimita angapo), kotero zotsatira zake zimayimira chidziwitso cha "mfundo". Kuti mumvetse momwe nthaka ilili ndi chinyezi m'munda wonse, mfundo zingapo ziyenera kukhazikitsidwa.
4. Kukhazikika ndi kusuntha kwa nthawi yayitali
Ngati chitsulo cha probe chikakwiriridwa m'nthaka kwa nthawi yayitali, chingakalamba chifukwa cha dzimbiri la electrolytic kapena mankhwala, zomwe zimapangitsa kuti miyeso iyende. Kuyang'anitsitsa nthawi zonse ndi kubwezeretsanso ndikofunikira.
Iii. Zochitika Zoyenera ndi Malangizo Osankha
Zochitika zoyenera kwambiri
Ulimi wanzeru ndi kuthirira moyenera: Kuyang'anira momwe nthaka imagwirira ntchito, kutsogolera nthawi yothirira ndi kuchuluka kwa madzi oti kuthirira, kukwaniritsa kusunga madzi ndi kuwonjezera kupanga.
Kusamalira malo obiriwira ndi bwalo la gofu: Zosewerera zazikulu za makina othirira okha.
Kafukufuku wa sayansi: Kafukufuku m'magawo monga zachilengedwe, madzi, ndi nyengo zomwe zimafuna kuyang'anira chinyezi cha nthaka kwa nthawi yayitali komanso mosalekeza.
Chenjezo loyambirira la masoka a nthaka: Yang'anirani chinyezi cha nthaka m'malo otsetsereka ndi m'mbali mwa misewu kuti muchenjeze za zoopsa za kugwa kwa nthaka.
Zochitika zomwe zimafuna kugwiritsa ntchito mosamala:
M'madera omwe muli mchere wambiri komanso nthaka yokhala ndi alkali yambiri: Pokhapokha ngati zitsanzo zopangidwa mwapadera komanso zoyesedwa bwino zagwiritsidwa ntchito, kudalirika kwa deta kumakhala kochepa.
Mu zitsimikizo za metrological zomwe zili ndi zofunikira kwambiri kuti zitsimikizidwe molondola: Pakadali pano, kungakhale kofunikira kuganizira masensa okwera mtengo a TDR kapena kugwiritsa ntchito mwachindunji njira yowumitsa.
Mwachidule, masensa oyezera nthaka omwe ali ndi mphamvu ndi njira "yotsika mtengo". Ngakhale kuti sizingapereke miyezo yeniyeni pamlingo wa labotale, zimatha kuwonetsa bwino momwe nthaka imasinthira komanso momwe chinyezi chimakhalira kuyambira chouma mpaka chonyowa. Pa zisankho zambiri zopangira ndi kuyang'anira, izi zili kale ndi phindu lalikulu. Kumvetsetsa bwino makhalidwe ake ndikuchita bwino pakuyesa ndiye njira yofunika kwambiri yogwiritsira ntchito bwino.
