Kulungile, ake sibheke ngokuningiliziwe izici zezinzwa zemvula neqhwa ezikwazi ukudlulisa ukukhanya.
Le sensor isetshenziswa kakhulu ukuthola ukuthi imvula iyenzeka yini nokuhlukanisa izinhlobo zemvula (imvula, iqhwa, okuxubile). Isimiso sayo esiyinhloko ukusebenzisa i-capacitor eveziwe ukukala ushintsho ku-dielectric constant yezinto eziwela phezu kwayo.
Incazelo emfushane yesimiso esiyinhloko
Ubuso bokuzwa benzwa buhlanganiswe yipuleti elilodwa noma ngaphezulu elinomthamo. Lapho imvula (amaconsi emvula noma amaqhwa eqhwa) iwela ebusweni bokuzwa, izoshintsha izakhiwo ze-dielectric phakathi kwamapuleti, ngaleyo ndlela ibangele izinguquko enanini le-capacitance. Ngenxa yezimo ezihlukene ze-dielectric zamanzi, iqhwa nomoya, ngokuhlaziya amaphethini, amazinga kanye nobukhulu bezinguquko ze-capacitance, kungenzeka ukunquma ukuthi kukhona imvula nokuthi ngabe yimvula noma iqhwa.
Izici eziyinhloko kanye nezinzuzo
1. Azikho izingxenye ezihambayo, ukuthembeka okuphezulu
Ngokungafani nama-rain gauge endabuko ebhakede eligobayo (anamabhakede agobayo omshini), izinzwa ezikwazi ukuthwala amanzi azinazo nhlobo izingxenye ezihambayo. Lokhu kunciphisa kakhulu ukungasebenzi kahle okubangelwa ukuguguleka komshini, ukuminyana (njengokuvinjelwa yisihlabathi, uthuli noma amaqabunga) noma ukubanda, kunezidingo eziphansi kakhulu zokunakekelwa kanye nokuphila isikhathi eside kwenkonzo.
2. Ingahlukanisa izinhlobo zemvula (imvula/iqhwa/ezixubile)
Lokhu kungenye yezinzuzo zayo ezivelele kakhulu. Ngokuhlaziya izici zezimpawu zomthamo ngokusebenzisa ama-algorithms, isimo sesigaba semvula singanqunywa. Kubalulekile ezimweni zokusetshenziswa ezidinga ukuqonda okunembile kwezinhlobo zemvula yasebusika (okubalulekile ekuthuthweni, ekushiseni, nasezixwayisweni zezolimo).
3. Ukuqina kwemvula okubonakalayo kanye nokuqongelela kwayo (kulinganiselwa)
Ngokulinganisa imvamisa kanye nobukhulu bezinguquko ze-capacitance, ubukhali kanye nenani eliqongelelekayo lemvula kungalinganiswa. Nakuba ukunemba kwayo okuphelele ngokuvamile kungabi kuhle njengokwebhakede elilinganiselwe noma ama-rain gauge alinganisiwe, kwanele ukuqapha izitayela kanye nokuhlaziywa kwekhwalithi/okulinganiselwe.
4. Impendulo esheshayo
Ingakwazi ukubona ukuqala nokuphela kwemvula encane kakhulu (njengokuna kwemvula kanye neqhwa elincane) ngaphandle kokulibala.
5. Ukusetshenziswa kwamandla okuphansi kanye nokuhlanganiswa okulula
Ifaneleka kakhulu ukuhlanganiswa neziteshi zezulu ezizenzakalelayo ezisebenza ngelanga futhi ingadlulisela idatha kude ngobuchwepheshe be-Intanethi Yezinto.
6. Ingakhipha ulwazi olucebile
Ayikwazi nje kuphela ukukhipha amasignali alula “anemvula/angenamvula”, kodwa futhi ikhipha ulwazi oluningi njengohlobo lwamakhodi emvula kanye namazinga okuqina kwemvula.
Ukulinganiselwa kanye Nezinselele
Ukunemba kokulinganisa kulinganiselwe (ikakhulukazi uma lina)
Ezimweni ezidinga ukulinganiswa okunembile kakhulu (njengocwaningo lwamanzi kanye nokubuka imvula emisebenzini yesimo sezulu), ngokuvamile akuyona into yokuqala ekhethwayo. Inani lemvula elilinganiswa yilo lithinteka kalula yizici ezifana nohlobo lwemvula, izinga lokushisa kanye nomoya, futhi lidinga ukulinganiswa kwendawo.
2. Ingaphazamiseka kalula uma kungekho mvula
Amazolo, isithwathwa kanye neqhwa elimanzi: Lawa manzi angenamvula anamathela ebusweni bokuzwa azobhekwa kabi yinzwa njengemvula ebuthakathaka kakhulu.
Uthuli, izinhlayiya zikasawoti, izinambuzane, indle yezinyoni: Noma iyiphi into enamathela endaweni yokuzwa ingashintsha inani le-capacitance, okuholela ezixwayisweni ezingamanga. Nakuba amanye amamodeli anezimbozo zokuzihlanza noma imisebenzi yokushisa ukuze kuncishiswe inkinga, ayinakuqedwa ngokuphelele.
Uthuli noma amanzi ashisayo emimoyeni enamandla: Kungase futhi kubangele i-trigger yamanga yesikhashana.
3. Kudingeka ukuhlanza nokulinganisa njalo
Ukuqinisekisa ukunemba kwedatha, indawo yokuzwa kumele igcinwe ihlanzekile futhi idinga ukuhlolwa nokugcinwa njalo. Ngemva kokusetshenziswa isikhathi eside, ukulinganiswa kabusha kungadingeka.
4. Izindleko ziphezulu kakhulu
Uma kuqhathaniswa ne-tipping bucket rain gauge elula, izingxenye zayo ze-elekthronikhi kanye nama-algorithms kuyinkimbinkimbi kakhulu, ngakho-ke izindleko zokuthenga zivame ukuba phezulu.
Uma kuqhathaniswa nengaphakathi legeyiji yemvula yebhakede eligoqayo
Izimo eziphakanyisiwe ezisebenzayo

Izimo ezifanele kakhulu
Ukuqapha isimo sezulu sethrafikhi: Njengoba ifakwe eceleni kwemigwaqo emikhulu, izikhumulo zezindiza kanye namabhuloho, ingaxwayisa ngokushesha ngezingozi zemigwaqo eshelelayo kanye neqhwa (imvula ephenduka iqhwa).
Iziteshi zezulu ezizenzakalelayo ezijwayelekile: Kudingeka bathole ulwazi mayelana nokuthi “kukhona yini imvula” kanye “nezinhlobo zemvula” usuku lonke futhi ngaphandle kokulungiswa okuningi.
Amadolobha ahlakaniphile kanye ne-inthanethi yezinto: Njengengxenye yenethiwekhi yokuqonda isimo sezulu sasemadolobheni, iqapha ukwenzeka kwemvula.
Kuyadingeka ukuhlukanisa phakathi kwezikhathi zemvula neqhwa, njengezindawo zokushushuluza eqhweni kanye nokusekelwa kwemicimbi yezemidlalo yasebusika.
Izimo ezinganconywa: Ezimweni lapho kudingeka khona ukunemba okuphezulu kakhulu ekulinganisweni kwemvula (njengokubuka kwesimo sezulu okusemthethweni kanye neziteshi zokubala amanzi), ibhakede lokuphonsa noma amageyiji emvula okukala kufanele kunikezwe kuqala njengemishini yokulinganisa eyinhloko. Izinzwa ze-capacitive zingasetshenziswa njengesengezo sokuhlonza izinhlobo zemvula.
Isifinyezo
Inzwa yemvula neqhwa enamandla “iyi-intelligent sentry”. Inani layo eliyinhloko alikho ekuhlinzekeni ngedatha yemvula enembile esezingeni lelabhorethri, kodwa ekutholeni ukwenzeka kanye nezinhlobo zezehlakalo zemvula ngendlela ethembekile nephansi, kanye nokunikeza ulwazi olubalulekile lwekhwalithi yezinhlelo zokwenza izinqumo ezenzakalelayo (njengokusebenza okuzenzakalelayo kwezinhlelo zokuncibilikisa iqhwa emgwaqweni). Lapho ekhetha, umuntu kufanele achaze ngokucacile ukuthi izidingo zakhe “ziwukulinganisa okunembile” noma “ukuhlonza okusheshayo”.
