Besisoloko silinganisa isantya somoya sisebenzisa ii-anemometers kangangeenkulungwane, kodwa inkqubela yakutshanje yenze kwaba nokwenzeka ukubonelela ngoqikelelo lwemozulu oluthembekileyo noluchanekileyo. Ii-anemometers zeSonic zilinganisa isantya somoya ngokukhawuleza nangokuchanekileyo xa kuthelekiswa neenguqulelo zemveli.
Amaziko esayensi yomoya adla ngokusebenzisa ezi zixhobo xa esenza imilinganiselo eqhelekileyo okanye izifundo ezineenkcukacha ukunceda ekwenzeni uqikelelo lwemozulu oluchanekileyo kwiindawo ezahlukeneyo. Iimeko ezithile zokusingqongileyo zinokunciphisa imilinganiselo, kodwa uhlengahlengiso oluthile lunokwenziwa ukuze koyiswe ezi ngxaki.
Ii-anemometers zavela kwinkulungwane ye-15 kwaye ziqhubekile nokuphuculwa nokuphuhliswa kwiminyaka yakutshanje. Ii-anemometers zemveli, ezaqala ukuphuhliswa phakathi kwinkulungwane ye-19, zisebenzisa ulungelelwaniso olujikelezayo lweekomityi zomoya eziqhagamshelwe kwi-data logger. Ngeminyaka yoo-1920, zaba ntathu, zibonelela ngempendulo ekhawulezayo nehambelanayo enceda ukulinganisa iingqimba zomoya. Ii-anemometers zeSonic ngoku zinyathelo elilandelayo ekuqikeleleni imozulu, zibonelela ngokuchaneka okukhulu kunye nesisombululo.
Ii-anemometers zeSonic, ezaphuhliswa ngeminyaka yoo-1970, zisebenzisa amaza e-ultrasonic ukulinganisa isantya somoya ngoko nangoko nokufumanisa ukuba amaza esandi ahamba phakathi kweesensa ezimbini ayakhawuleziswa okanye ayacothiswa ngumoya.
Ngoku zithengiswa kakhulu kwaye zisetyenziswa kwiinjongo ezahlukeneyo nakwiindawo ezahlukeneyo. Ii-anemometers ze-sonic ezinemilinganiselo emibini (isantya somoya kunye nesikhokelo) zisetyenziswa kakhulu kwizikhululo zemozulu, kwiinqanawa, kwiiturbines zomoya, kwiinqwelomoya, kwanasembindini wolwandle, zidada kwii-buoys zemozulu.
Ii-anemometer zeSonic zinokwenza imilinganiselo enesisombululo sexesha esiphezulu kakhulu, ngesiqhelo ukusuka kwi-20 Hz ukuya kwi-100 Hz, nto leyo eyenza ukuba zifaneleke kakuhle kwiimilinganiselo ze-turbulence. Isantya kunye nezisombululo kwezi zigaba zivumela imilinganiselo echanekileyo ngakumbi. I-anemometer yesonic yenye yezixhobo zemozulu zamva nje kwizikhululo zemozulu namhlanje, kwaye ibaluleke ngakumbi kune-wind vane, elinganisa icala lomoya.
Ngokungafaniyo neenguqulelo zemveli, i-anemometer yesandi ayifuni zixhobo zishukumayo ukuze isebenze. Zilinganisa ixesha elithathwayo ukuze isandi sihambe phakathi kwezi sensor ezimbini. Ixesha limiselwa ngumgama ophakathi kwezi sensor, apho isantya sesandi sixhomekeke kubushushu, uxinzelelo kunye nezinto ezingcolisayo zomoya ezifana nongcoliseko, ityuwa, uthuli okanye inkungu emoyeni.
Ukuze ufumane ulwazi ngesantya somoya phakathi kwezinzwa, isenzi ngasinye sisebenza ngokutshintshana njengomthumeli kunye nomkeli, ngoko ke iipulse zidluliselwa phakathi kwazo kumacala omabini.
Isantya sokubhabha simiselwa ngokusekelwe kwixesha lokubetha kwentliziyo kwicala ngalinye; sibamba isantya somoya esinemilinganiselo emithathu, icala kunye ne-engile ngokubeka ii-sensors ezintathu kwii-axes ezintathu ezahlukeneyo.
IZiko leSayensi yeMkhathi linama-anemometer alishumi elinesithandathu esandi, elinye lawo likwazi ukusebenza kwi-100 Hz, amabini kuwo akwazi ukusebenza kwi-50 Hz, kwaye amanye, uninzi lwawo lukwazi ukusebenza kwi-20 Hz, akhawuleza ngokwaneleyo kwimisebenzi emininzi.
Izixhobo ezimbini zixhotyiswe ngokufudumeza okuthintela umkhenkce ukuze zisetyenziswe kwiimeko ezibandayo. Uninzi lwazo lunee-analog inputs, ezikuvumela ukuba wongeze ezinye ii-sensors ezifana nobushushu, ukufuma, uxinzelelo kunye neegesi ezilandelelanayo.
Ii-anemometer zeSonic zisetyenzisiwe kwiiprojekthi ezifana neNABMLEX ukulinganisa isantya somoya kwiindawo ezahlukeneyo eziphakamileyo, kwaye iCityflux ithathe imilinganiselo eyahlukeneyo kwiindawo ezahlukeneyo zesixeko.
Iqela leprojekthi yeCityFlux, elifunda ngongcoliseko lomoya ezidolophini, lithe: “Ingongoma yeCityFlux kukufunda zombini ezi ngxaki ngaxeshanye ngokulinganisa ukuba imimoya enamandla isusa ngokukhawuleza kangakanani izinto ezincinci kwinethiwekhi yeendlela zesixeko ‘zemigxobhozo’. Umoya ongaphezulu kwazo yindawo esihlala kuyo nesiphefumlayo. Indawo enokufuthwa ngumoya.”
Ii-anemometers zeSonic zezona zinto ziphambili zamva nje ekulinganiseni isantya somoya, ziphucula ukuchaneka kweziganeko zemozulu kwaye zikhuselekile kwiimeko ezimbi ezifana nemvula enkulu enokubangela iingxaki ngezixhobo zemveli.
Idatha echanekileyo ngakumbi yesantya somoya isinceda siqonde iimeko zemozulu ezizayo kwaye silungiselele ubomi bemihla ngemihla nomsebenzi.
