Iziteshi zesimo sezulu ziyiphrojekthi ethandwayo yokuzama ngezinzwa ezahlukene zemvelo, futhi i-cup anemometer elula kanye ne-weather vane ngokuvamile kukhethwa ukunquma isivinini somoya kanye nesiqondiso. Kwi-QingStation kaJianjia Ma, wanquma ukwakha uhlobo oluhlukile lwenzwa yomoya: i-ultrasonic anemometer.
Ama-anemometer e-Ultrasonic awanazo izingxenye ezihambayo, kodwa ukuhweba kuwukwanda okukhulu kobunzima be-elekthronikhi. Asebenza ngokulinganisa isikhathi esithathwayo ukuze i-pulse yomsindo we-ultrasonic ibonakale kumuntu omukelayo ebangeni elaziwayo. Isiqondiso somoya singabalwa ngokuthatha ukufundwa kwesivinini kusuka kuma-pair amabili ezinzwa ze-ultrasonic eziqondile komunye nomunye nokusebenzisa i-trigonometry elula. Ukusebenza kahle kwe-anemometer ye-ultrasonic kudinga ukwakheka ngokucophelela kwe-analog amplifier ekugcineni kokwamukela kanye nokucubungula okubanzi kwesignali ukuze kukhishwe isignali efanele kuma-echoes esibili, ukusabalala kwezindlela eziningi, kanye nawo wonke umsindo obangelwa imvelo. Izinqubo zokuklama kanye nokuhlola zibhalwe kahle. Njengoba u-[Jianjia] engakwazi ukusebenzisa umhubhe womoya ukuhlola nokulinganisa, wafaka i-anemometer okwesikhashana ophahleni lwemoto yakhe wabe esehamba. Inani eliphumelayo lilingana nesivinini se-GPS semoto, kodwa liphakeme kancane. Lokhu kungaba ngenxa yamaphutha okubala noma izici zangaphandle njengokuphazamiseka komoya noma ukuhamba komoya okuvela emotweni yokuhlola noma eminye imigwaqo.
Ezinye izinzwa zifaka phakathi izinzwa zemvula ezibonakalayo, izinzwa zokukhanya, izinzwa zokukhanya kanye ne-BME280 yokulinganisa umfutho womoya, umswakama kanye nokushisa. UJianjia uhlela ukusebenzisa i-QingStation esikebheni esizimele, ngakho-ke wanezela ne-IMU, ikhampasi, i-GPS, kanye nemakrofoni yomsindo we-ambient.
Ngenxa yentuthuko yezinzwa, izinto zikagesi, kanye nobuchwepheshe bokwenza amaphrothokholi, ukwakha isiteshi sezulu somuntu siqu kulula kunanini ngaphambili. Ukutholakala kwamamojula enethiwekhi ashibhile kusenza sikwazi ukuqinisekisa ukuthi lawa madivayisi e-IoT angadlulisela ulwazi lwawo kuzizindalwazi zomphakathi, anikeze imiphakathi yendawo idatha yesimo sezulu efanele endaweni ezungezile.
UManolis Nikiforakis uzama ukwakha i-Weather Pyramid, idivayisi yokulinganisa isimo sezulu eqinile, engenazo zonke izinsiza, enamandla kanye nokuxhumana eyenzelwe ukuthunyelwa okukhulu. Ngokuvamile, iziteshi zesimo sezulu zihlonyiswe ngezinzwa ezilinganisa izinga lokushisa, ingcindezi, umswakama, isivinini somoya kanye nemvula. Nakuba iningi lala mapharamitha lingalinganiswa kusetshenziswa izinzwa zesimo esiqinile, ukunquma isivinini somoya, isiqondiso, kanye nemvula ngokuvamile kudinga uhlobo oluthile lwedivayisi kagesi.
Ukwakheka kwezinzwa ezinjalo kuyinkimbinkimbi futhi kuyinselele. Uma uhlela ukuthunyelwa okukhulu, udinga futhi ukuqinisekisa ukuthi kuyabiza, kulula ukukufaka, futhi akudingi ukulungiswa njalo. Ukuqeda zonke lezi zinkinga kungaholela ekwakhiweni kweziteshi zezulu ezithembekile nezingabizi kakhulu, ezingafakwa ngobuningi ezindaweni ezikude.
UManolis unemibono ethile yokuthi angazixazulula kanjani lezi zinkinga. Uhlela ukubamba isivinini somoya kanye nesiqondiso kusuka ku-accelerometer, i-gyroscope kanye nekhampasi kuyunithi yenzwa ye-inertial (IMU) (mhlawumbe i-MPU-9150). Uhlelo ukulandelela ukunyakaza kwenzwa ye-IMU njengoba ijika ngokukhululeka kukhebula, njenge-pendulum. Wenze izibalo ezithile ku-napkin futhi ubonakala eqiniseka ukuthi zizonikeza imiphumela ayidingayo lapho ehlola i-prototype. Ukuzwa imvula kuzokwenziwa kusetshenziswa izinzwa ze-capacitive kusetshenziswa inzwa ezinikele njenge-MPR121 noma umsebenzi wokuthinta owakhelwe ngaphakathi ku-ESP32. Ukwakheka nendawo yemizila ye-electrode kubaluleke kakhulu ekulinganisweni kwemvula okulungile ngokuthola amaconsi emvula. Usayizi, ukuma kanye nokusatshalaliswa kwesisindo sendlu lapho inzwa ifakwe khona nakho kubalulekile njengoba kuthinta ububanzi, ukuxazululwa kanye nokunemba kwethuluzi. UManolis usebenza emibonweni eminingana yokuklama ahlela ukuyizama ngaphambi kokunquma ukuthi isiteshi sezulu sonke sizoba ngaphakathi kwendlu ejikelezayo noma izinzwa ezingaphakathi kuphela.
Ngenxa yesithakazelo sakhe kwi-meteorology, u-[Karl] wakha isiteshi sezulu. Esisha kakhulu salezi yi-ultrasonic wind sensor, esebenzisa isikhathi sokundiza kwama-ultrasonic pulses ukunquma isivinini somoya.
Inzwa kaCarla isebenzisa ama-transducer amane e-ultrasonic, aqondiswe enyakatho, eningizimu, empumalanga nasentshonalanga, ukuthola isivinini somoya. Ngokulinganisa isikhathi esithathwayo ukuze i-pulse ye-ultrasonic ihambe phakathi kwezinzwa egumbini bese sisusa izilinganiso zensimu, sithola isikhathi sokundiza kwe-axis ngayinye ngakho-ke isivinini somoya.
Lokhu kuwukubonakaliswa okumangalisayo kwezixazululo zobunjiniyela, okuhambisana nombiko womklamo onemininingwane emangalisayo.
