I-Anemometer ye-ultrasonic

Izikhululo zemozulu yiprojekthi edumileyo yokuzama izixhobo ezahlukeneyo zokusingqongileyo, kwaye ikomityi elula ye-anemometer kunye nemozulu yemozulu zihlala zikhethwa ukumisela isantya somoya kunye nelathiso.Kwi-Jianjia Ma's QingStation, wagqiba ekubeni akhe uhlobo olwahlukileyo lwenzwa yomoya: i-anemometer ye-ultrasonic.
I-anemometers ye-Ultrasonic ayinazo iindawo ezihambayo, kodwa ukurhweba kukunyuka okuphawulekayo kobunzima be-elektroniki.Basebenza ngokulinganisa ixesha elithathwayo kwi-ultrasonic sound pulse ukubonisa kumamkeli kumgama owaziwayo.Ulwalathiso lomoya lungabalwa ngokuthatha ukufundwa kwesantya ukusuka kwizibini ezimbini ze-ultrasonic sensors perpendicular to each other kunye nokusebenzisa i-trigonometry elula.Ukusebenza ngokufanelekileyo kwe-anemometer ye-ultrasonic kufuna ukucwangciswa ngokucophelela kwe-analog amplifier ekupheleni kokufumana kunye nokulungiswa kwesignali ebanzi ukukhupha isignali echanekileyo kwii-echoes zesibini, ukusasazwa kwe-multipath, kunye nayo yonke ingxolo ebangelwa yindalo.Uyilo kunye neenkqubo zovavanyo zibhalwe kakuhle.Ekubeni [uJianjia] engazange akwazi ukusebenzisa itonela yomoya ukuze avavanye aze alungelelanise, okwexeshana wafaka ianemometer kuphahla lwenqwelo-mafutha yakhe waza wemka.Ixabiso lesiphumo lilingana nesantya seGPS semoto, kodwa siphezulu kancinci.Oku kusenokuba ngenxa yeempazamo zokubala okanye imiba yangaphandle efana nokuphazamiseka komoya okanye ukuqukuqela komoya kwisithuthi sovavanyo okanye ezinye iindlela zokuhamba.
Abanye abenzi boluvo babandakanya abenzi boluvo bemvula, izibonisi zokukhanya, izinzwa zokukhanya kunye ne-BME280 zokulinganisa uxinzelelo lomoya, ukufuma kunye nobushushu.UJianjia uceba ukusebenzisa iQingStation kwisikhephe esizimeleyo, ngoko ke wongeze i-IMU, ikhampasi, iGPS, kunye nemakrofoni yesandi esijikeleze.
Enkosi kwinkqubela phambili yezoluvo, i-elektroniki, kunye netekhnoloji yeprototyping, ukwakha isikhululo semozulu somntu kulula kunangaphambili.Ukufumaneka kweemodyuli zenethiwekhi eziphantsi kwexabiso eliphantsi kusivumela ukuba siqinisekise ukuba ezi zixhobo ze-IoT zinokudlulisela ulwazi lwazo kwiinkcukacha zoluntu, ukubonelela uluntu lwasekuhlaleni ngedatha yemozulu efanelekileyo kwiindawo ezingqongileyo.
UManolis Nikiforakis uzama ukwakha iPiramidi yeMozulu, i-solid-state, isondlo-free, i-energy- kunye nonxibelelwano-isixhobo sokulinganisa imozulu esizimeleyo esilungiselelwe ukuhanjiswa okukhulu.Ngokuqhelekileyo, izikhululo zemozulu zixhotyiswe ngezava zokubona ubushushu, uxinzelelo, ukufuma, isantya somoya kunye nemvula.Ngelixa uninzi lwezi pharamitha zinokulinganiswa kusetyenziswa izinzwa zemeko eqinileyo, ukufumanisa isantya somoya, icala, kunye nemvula kufuna uhlobo oluthile lwesixhobo sombane.
Uyilo lwezinzwa ezinjalo luntsonkothile kwaye lucelomngeni.Xa ucwangcisa ukuthunyelwa okukhulu, kufuneka uqinisekise ukuba zibiza iindleko, kulula ukuzifaka, kwaye azifuni ukulungiswa rhoqo.Ukuphelisa zonke ezi ngxaki kunokukhokelela ekwakhiweni kwezikhululo zemozulu ezithembeke ngakumbi nezingabizi kakhulu, ezinokuthi emva koko zifakwe ngobuninzi kwiindawo ezikude.
UManolis unezimvo ezithile ngendlela yokusombulula ezi ngxaki.Uceba ukubamba isantya somoya kunye nolwalathiso oluvela kwi-accelerometer, i-gyroscope kunye nekhampasi kwiyunithi ye-inertial sensor (IMU) (mhlawumbi i-MPU-9150).Isicwangciso kukulandelela ukuhamba kwe-sensor ye-IMU njengoko ijikeleza ngokukhululekile kwintambo, njenge-pendulum.Wenze izibalo ezithile kwi-napkin kwaye ubonakala eqinisekile ukuba baya kunika iziphumo azifunayo xa evavanya iprototype.Ukuvakalelwa kwemvula kuya kwenziwa ngokusebenzisa i-capacitive sensors usebenzisa i-sensor ezinikeleyo njenge-MPR121 okanye i-touch-in touch function kwi-ESP32.Uyilo kunye nendawo yeengoma ze-electrode zibaluleke kakhulu kumlinganiselo ochanekileyo wemvula ngokufumanisa amathontsi emvula.Ubungakanani, imilo kunye nokusabalalisa ubunzima bezindlu apho i-sensor ifakwe khona nayo ibaluleke kakhulu njengoko ichaphazela uluhlu, isisombululo kunye nokuchaneka kwesixhobo.UManolis usebenza kwiingcamango zoyilo ezininzi aceba ukuzizama ngaphambi kokuba athathe isigqibo sokuba isikhululo semozulu sisonke siya kuba ngaphakathi kwizindlu ezijikelezayo okanye abenzi boluvo ngaphakathi.
Ngenxa yomdla wakhe kwi-meteorology, [uKarl] wakha isikhululo semozulu.Esona sikhululo sitsha kwezi yi-ultrasonic wind sensor, esebenzisa ixesha lokubhabha le-ultrasonic pulses ukumisela isantya somoya.
Inzwa yeCarla isebenzisa ii-transducers ezine ze-ultrasonic, ezijoliswe ngasentla, emazantsi, empuma nasentshona, ukufumanisa isantya somoya.Ngokulinganisa ixesha elithathayo ukuba i-pulse ye-ultrasonic ihambe phakathi kweenzwa kwigumbi kwaye ikhuphe imilinganiselo yentsimi, sifumana ixesha lokuhamba kwi-axis nganye kwaye ngoko isantya somoya.
Lo ngumboniso ochukumisayo wezisombululo zobunjineli, ukhatshwa yingxelo yoyilo eneenkcukacha emangalisayo.
