Kwixesha le-lidar, ii-microwave sensors, kunye nokuqikelela i-AI, isixhobo seplastiki esixabisa ngaphantsi kwekhulu leedola sisasebenza njengomlinganiselo wemvula osisiseko kwi-90% yezikhululo zemozulu zehlabathi—ubomi baso obuhlala buhleli buvela phi?
Ukuba uvula isikhululo semozulu esizenzekelayo sanamhlanje, uza kufumanisa ukuba i-core rain sensor ayisiyontloko yelaser ekhanyayo okanye i-antenna ye-microwave enobuchule, kodwa sisixhobo esilula esenziwe ngebhakethi yeplastiki ejikajikayo, iimagnethi, kunye neswitshi yereed—i-rain gauge ye-tipping-bucket rain gauge.
Ukususela oko injineli yaseIreland uThomas Robinson waqala ukuyila iprototype yayo ngo-1860, olu yilo aluzange lutshintshe kangangeminyaka engaphezu kwe-160. Namhlanje, luye lwavela kwi-brass castings ukuya kwi-injection-molded plastic, ukusuka ekufundeni ngesandla ukuya kwi-electronic signal output, kodwa umgaqo-siseko walo uhlala ufana: vumela i-raindrop nganye iqhube i-mechanical lever echanekileyo, iyiguqule ibe yidatha enokulinganiswa.
Ifilosofi yoYilo: Ubulumko bobuNcinci
Intliziyo ye-tipping-bucket rain gauge yinkqubo yokulinganisela ene-dual-bucket:
- I-funnel eqokelelayo ikhokelela imvula kwenye yeebhakethi.
- Ibhakethi nganye ilinganiswe ngokuchanekileyo (ngokuvamile imvula eyi-0.2mm okanye i-0.5mm ngencam nganye).
- I-magnet kunye ne-reed switch zivelisa i-electrical pulse rhoqo xa ibhakethi ijika.
- I-data logger ibala ii-pulses, iphindaphinde ngexabiso lokulinganisa ukuze ibale imvula iyonke.
Ubuhle bale ndlela yoyilo bukwizinto ezilandelayo:
- Ukusebenza okungasebenziyo: Kulinganisa imvula ngokwasemzimbeni ngaphandle kokusebenzisa umbane (i-elektroniki yenzelwe ukuguqulwa kwesiginali kuphela).
- Ukuzihlanza: Ibhakethi iphinda iqalise ngokuzenzekelayo emva kwencam nganye, nto leyo evumela ukulinganiswa okuqhubekayo.
- Impendulo ethe tye: Ngaphakathi kobukhulu bemvula obuyi-0–200mm/h, impazamo ingalawulwa ngaphakathi kwe-±3%.
Ukuphila Kwanamhlanje: Kutheni iHigh-Tech ingazange iyithathe indawo yayo
Njengoko izixhobo zemozulu zisiya kwixabiso eliphezulu kunye nokuchaneka, i-rain gauge yeplastiki ejika ibambe indawo yayo ngeenzuzo ezine eziphambili:
1. Ixabiso Elingalinganiyo Nelisebenzayo
- Ixabiso leyunithi yesenzi senzwa yodidi lobungcali: $500–$5,000
- Ixabiso leyunithi yegeyiji yemvula yeplastiki esetyenziswa njengebhakede: $20–$200
- Xa kusakhiwa iinethiwekhi zokujonga imvula ezinobuninzi kwihlabathi liphela, umahluko weendleko ungabandakanya iindidi ezimbini zobukhulu.
2. Umgangatho wokusebenza ophantsi kakhulu
- Akukho mfuneko yokulinganisa ngobuchule, kufuneka kucocwe izihluzi rhoqo kwaye kujongwe amanqanaba azo.
- Iinethiwekhi zemozulu ezizinikeleyo kumazantsi eSahara eAfrika zixhomekeke kumawaka eegeyiji ezilula zokwakha iidathabheyisi zemvula yengingqi okokuqala.
3. Ukuthelekiswa kwedatha kunye nokuqhubekeka kwayo
- I-80% yedatha yochungechunge lwemvula oluthathe inkulungwane yonke ehlabathini ivela kwi-tipping-bucket okanye kwi-siphon rain gauge yangaphambili.
- Itekhnoloji entsha kufuneka "ihambelane" nedatha yembali, kwaye idatha yokufumana amacebiso isebenza njengesiseko sophando lwemozulu.
4. Ukuqina kwiindawo ezingaqhelekanga
- Ngexesha lezikhukula zaseJamani zango-2021, iigeyiji ezininzi zemvula ze-ultrasonic kunye neze-radar azizange ziphumelele ngenxa yokucinywa kombane, ngelixa iibhakethi zoomatshini ezijikayo zaziqhubeka nokurekhoda lonke isiphepho kwiibhetri ezincedisayo.
- Kwizikhululo ezingenabantu kwiindawo ezisemantla okanye ezikwiindawo eziphakamileyo, ukusetyenziswa kwayo kwamandla aphantsi (malunga ne-1 kWh ngonyaka) kwenza ukuba ibe lukhetho olungenakutshintshwa.
Impembelelo yokwenyani: Iimeko ezintathu ezibalulekileyo
Ityala 1: Inkqubo Yesilumkiso Ngezikhukula eBangladesh
Ilizwe lithumele iigeyiji zemvula ezilula zeplastiki ezili-1,200 kulo lonke iBrahmaputra Delta, apho abemi belali babika ukufundwa kwemihla ngemihla ngeSMS. Olu "thungelwano lobuchwephesha obuphantsi" lwandise amaxesha okulumkisa ngezikhukula ukusuka kwiiyure ezi-6 ukuya kwezingama-48, lusindisa amakhulu abantu ngonyaka, ngexabiso lokwakha elilingana neradar enye yemozulu yeDoppler ephezulu.
Ityala lesi-2: Uvavanyo loMngcipheko woMlilo wasendle waseCalifornia
Isebe lezamahlathi lifake iinethiwekhi zokulinganisa imvula ezisebenzisa amandla elanga kwiindawo ezibalulekileyo ukuze kujongwe imvula yexesha elifutshane ebalulekileyo ekubaleni "isalathisi sokutsha". Ngo-2023, le nkqubo inike inkxaso echanekileyo kwisigqibo semozulu kwimisebenzi engama-97 yokutshisa emiselweyo.
Ityala 3: Ukubamba “Iindawo Ezishushu” Zezikhukula Zasezidolophini
IBhodi yeeNkonzo zoLuntu yaseSingapore yongeze izixhobo zokuvavanya amanzi ezikwiindlu, kwiindawo zokupaka iimoto, nakwiindawo zokukhupha amanzi, ichonga "iindawo ezintathu zemvula encinci" eziphoswe ziinethiwekhi zezikhululo zemozulu zemveli, yaphucula isicwangciso sokuphucula amanzi amdaka esixabisa i-S$200 yezigidi ngokufanelekileyo.
Iklasikhi Eguqukayo: Xa Oomatshini Bedibana Nobukrelekrele
Isizukulwana esitsha seegeyiji zemvula ezisebenzisa i-tipping-bucket siyaphucuka kancinci kancinci:
- Ukuhlanganiswa kwe-IoT: Ixhotyiswe ngeemodyuli zeNarrowband IoT (NB-IoT) zokuhambisa idatha ekude.
- Imisebenzi Yokuzixilonga: Ukufumanisa ukuvaleka okanye iimpazamo zoomatshini ngokusebenzisa amaxesha angaqhelekanga okujika.
- Utshintsho lwezinto: Ukusebenzisa iplastiki ye-ASA engangeni kwi-UV, okwandisa ubomi bayo ukusuka kwiminyaka emi-5 ukuya kweli-15.
- Intshukumo ye-Open-Source: Iiprojekthi ezifana ne-"RainGauge" yase-UK zibonelela ngoyilo oluprintwayo lwe-3D kunye nekhowudi ye-Arduino, zikhuthaza ukuthatha inxaxheba kwisayensi yoluntu.
Imida Yayo: Ukwazi Imida Yokuyisebenzisa Kakuhle
Kakade ke, i-tipping-bucket rain gauge ayigqibelelanga:
- Xa imvula inamandla angaphezulu kwe-200mm/h, iibhakethi zisenokungaphindi zibuyele esiqhelweni ngexesha, nto leyo ekhokelela ekubeni inani lazo lingabi likhulu.
- Imvula eqinileyo (ikhephu, isichotho) ifuna ukuba ukufudumeza kunyibilike ngaphambi kokuba kulinganiswe.
- Imiphumo yomoya inokubangela iimpazamo ekubambeni amanzi (ingxaki exhaphakileyo kuzo zonke iigeyiji zemvula ezisemhlabeni).
Isiphelo: Ukuthembeka ngaphezu kokugqibelela
Kwixesha elixakeke kakhulu bubuhle betekhnoloji, i-plastic tipping-bucket rain gauge isikhumbuza inyaniso ehlala ilityalwa: Kwiziseko zophuhliso, ukuthembeka kunye nokukhula kudla ngokuba yinto ebaluleke ngaphezu kokuchaneka ngokupheleleyo. Yi-"AK-47" yokujonga imvula—isakhiwo sayo silula, ixabiso liphantsi, iguquguqukayo kakhulu, kwaye ngaloo ndlela ifumaneka kuyo yonke indawo.
Ithontsi ngalinye lemvula eliwela kwi-funnel yalo lithatha inxaxheba ekwakheni umaleko wedatha osisiseko ukuze uluntu luqonde inkqubo yemozulu. Esi sixhobo seplastiki sithobekileyo, eneneni, sibhuloho elula kodwa eqinileyo edibanisa ukubonwa komntu ngamnye nesayensi yehlabathi, iintlekele zasekuhlaleni kunye nesenzo semozulu.
Iseti epheleleyo yeeseva kunye nemodyuli engenazingcingo yesoftware, ixhasa i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
