Izinzwa zomhlaba ezikwaziyo ukuthwala amandla zezinye zezona ndlela zixhaphakileyo zokulinganisa ukufuma komhlaba zanamhlanje (ngokuqhelekileyo ziyinxalenye yohlobo lwe-frequency-domain reflectometry (FDR)). Umgaqo ophambili kukufumana ngokungathanga ngqo umxholo womswakama womhlaba ngokulinganisa i-dielectric constant yayo. Ekubeni i-dielectric constant yamanzi (malunga nama-80) iphezulu kakhulu kunezinye izinto emhlabeni (malunga ne-1 yomoya kunye ne-3-5 ye-matrix yomhlaba), utshintsho olupheleleyo kwi-dielectric constant yomhlaba luxhomekeke kakhulu kumxholo womswakama.
Nazi iimpawu zayo eziphambili:
I. Amandla angundoqo kunye neenzuzo
1. Ixabiso eliphantsi kwaye kulula ukulidumisa
Xa kuthelekiswa nee-sensors ze-reflectometry yexesha elichanekileyo (TDR), ii-capacitive sensors zinezixhobo ze-elektroniki eziphantsi kunye neendleko zokuvelisa, nto leyo evumela ukuba zisetyenziswe kakhulu kwiimeko ezifuna ukusasazwa okukhulu, ezifana nezolimo ezikrelekrele kunye nokunkcenkceshela igadi.
2. Ukusetyenziswa kwamandla aphantsi kakhulu
Iisekethe zokulinganisa amandla ngokwazo zinokusetyenziswa kwamandla aphantsi kakhulu kwaye zifanelekile kakhulu ekubekweni esweni ixesha elide kunye nokusetyenziswa kwe-Intanethi yezinto ezisebenza ngeebhetri kunye neephaneli zelanga. Zingasebenza ngokuqhubekayo kangangeenyanga okanye iminyaka.
3. Ingajongwa rhoqo ixesha elide
Xa kuthelekiswa nendlela yokomisa efuna ukusetyenziswa ngesandla, izinzwa ezikwaziyo ukufunxa amanzi zinokungcwatywa emhlabeni ukuze ziqhube ukuqokelela idatha ngokuzenzekelayo, okungacwangciswanga, kwaye zinokubamba inkqubo yokutshintsha komswakama womhlaba, njengempembelelo yokunkcenkceshela, imvula kunye nokufuma.
4. Incinci ngobukhulu kwaye kulula ukuyifaka
Iisensors zihlala ziyilwe njengeeprobes. Gqobhoza nje umngxuma kwindawo yokulinganisa uze ufake iprobe ngokuthe nkqo emhlabeni, ungenzi monakalo mkhulu kwisakhiwo somhlaba.
5. Uzinzo oluhle kwaye akukho monakalo we-radioactivity
Ngokungafaniyo neemitha ze-neutron, ii-capacitive sensors azibandakanyi nayiphi na imithombo ye-radioactive, zikhuselekile ukuzisebenzisa, kwaye azidingi mvume okanye ukhuseleko olukhethekileyo.
6. Iyadibaniswa kwaye ikrelekrele
Kulula kakhulu ukudibana nabaqokeleli bedatha kunye neemodyuli zothumelo ezingenazingcingo (ezifana ne-4G/LoRa/NB-IoT) ukuze kwenziwe inethiwekhi epheleleyo yokujonga ukufuma komhlaba. Abasebenzisi banokujonga idatha bekude ngexesha langempela ngeefowuni eziphathwayo okanye iiplatifomu zekhompyutha.
Ii. Imida kunye nemingeni
Ukuchaneka komlinganiselo kuchatshazelwa zizinto ezininzi
Impembelelo yokwakheka komhlaba: Ii-calibration curves zodongwe, i-loam kunye nomhlaba onesihlabathi zahlukile. Ii-sensors zihlala zilinganiswa ngesanti esemgangathweni kunye nomhlaba xa ziphuma kwifektri. Ukusetyenziswa ngokuthe ngqo kwimihlaba eneempawu ezahlukeneyo kuya kubangela iimpazamo.
Impembelelo yokuqhuba umbane womhlaba (ityuwa): Le yenye yezona mithombo ziphambili zempazamo kwiisensa ze-capacitive. Ii-ion zetyuwa emhlabeni zinokuphazamisana namasimi e-electromagnetic, nto leyo ebangela ukuba amaxabiso alinganisiweyo abe phezulu. Kumhlaba onetyuwa, ukuchaneka kokulinganisa kuya kwehla kakhulu.
Impembelelo yokuxinana komhlaba kunye nokuvuleka kwawo: Ukuba iprobe isondelelene nomhlaba nokuba kukho iimbobo ezinkulu okanye amatye emhlabeni konke oku kuya kuchaphazela ukuchaneka kweziphumo zokulinganisa.
Impembelelo yobushushu: Ukungaguquguquki kwe-dielectric kuyatshintsha ngokweqondo lobushushu. Iisensa ezikumgangatho ophezulu zineesensa zobushushu ezakhelwe ngaphakathi zokuhlawula, kodwa isiphumo sokuhlawula silinganiselwe.
2. Ukulinganiswa kwendawo kuyafuneka
Ukuze kufunyanwe iziphumo zokulinganisa ezichanekileyo, ingakumbi kwiintlobo ezithile zomhlaba, kufuneka ukulinganiswa kwindawo ethile. Oko kukuthi, iisampulu zomhlaba ziyaqokelelwa, umxholo wokwenyani womswakama ulinganiswa ngendlela eqhelekileyo yokomisa, uze uthelekiswe nokufundwa kwesensor ukuze kusekwe i-localized calibration equation. Eli linyathelo elibalulekileyo lokuqinisekisa ukuchaneka kwedatha, kodwa ikwanyusa iindleko zokusetyenziswa kunye nomda wobugcisa.
3. Uluhlu lokulinganisa lukwindawo ethile
Uluhlu lokulinganisa lwesensor lukhawulelwe kumthamo oqingqiweyo womhlaba ojikeleze iprobe (oko kukuthi, "indawo ebuthathaka" yesensor). Le ndawo idla ngokuba ncinci kakhulu (iisentimitha ezimbalwa zetyhubhu), ngoko ke isiphumo sokulinganisa simele ulwazi "lwenqaku". Ukuze kuqondwe iimeko zokufuma komhlaba kwintsimi yonke, kufuneka kumiselwe amanqaku amaninzi.
4. Uzinzo kunye nokushukuma kwexesha elide
Ukuba igqunywe emhlabeni ixesha elide, isinyithi seprobe sinokuguga ngenxa yokubola kwe-electrolytic okanye isenzo seekhemikhali, nto leyo ebangela ukuba amaxabiso okulinganisa ahambe. Kufuneka uhlolo rhoqo kunye nokulungiswa kwakhona.
Iingcebiso Ezisebenzayo Nezendlela Zokukhetha
Iimeko ezifanelekileyo kakhulu
Ulimo olukrelekrele kunye nokuNcedisa ngokuLungileyo: Ukubeka esweni ukufuma komhlaba, ukukhokela ixesha lokunkcenkceshela kunye nokuba amanzi angakanani, ukufikelela ekulondolozweni kwamanzi kunye nokwanda kwemveliso.
Ukulungiswa kwezityalo eziluhlaza kunye nebala legalufa: Izinzwa eziphambili zeenkqubo zokunkcenkceshela ezizenzekelayo.
Uphando lwezenzululwazi: Uphando kwiindawo ezifana ne-ecology, i-hydrology, kunye ne-meteorology olufuna ukujongwa ixesha elide nokuqhubekayo kokufuma komhlaba.
Isilumkiso sakwangoko sentlekele yejografi: Jonga ukufuma komhlaba kwiindawo ezithe tyaba nakwiindlela ukuze ulumkise ngeengozi zokudilika komhlaba.
Imeko ezifuna ukusetyenziswa ngononophelo:
Kwiindawo ezinomhlaba onetyuwa eninzi kunye nomhlaba one-alkali ephezulu: Ngaphandle kokuba kusetyenziswe iimodeli ezilungiselelwe ngokukodwa nezilinganisiweyo, ukuthembeka kwedatha kuphantsi.
Kwiimeko zesatifikethi semetrological ezineemfuno eziphezulu kakhulu zokuchaneka ngokupheleleyo: Okwangoku, kunokufuneka ucinge ngee-sensors ze-TDR ezibizayo okanye usebenzise ngokuthe ngqo indlela yokomisa.
Ngamazwi alula, izinzwa zomhlaba ezikwaziyo ukusebenza ziyindlela "engabizi kakhulu". Nangona isenokungabi namaxabiso achanekileyo kwinqanaba lelebhu, inokubonisa kakuhle utshintsho oluhambelanayo kunye nepateni yokufuma komhlaba ukusuka komile ukuya kumanzi. Kwizigqibo ezininzi zemveliso kunye nolawulo, oku sele kunexabiso elikhulu. Ukuqonda ngokuchanekileyo iimpawu zayo kunye nokwenza umsebenzi olungileyo ekulinganiseni zezona zinto zibalulekileyo ekuyisebenziseni kakuhle.
