Tave tichiyera kumhanya kwemhepo tichishandisa ma anemometers kwemazana emakore, asi kufambira mberi kwazvino kwakaita kuti zvikwanisike kupa fungidziro dzemamiriro ekunze dzakavimbika uye dzakarurama. Ma anemometers eSonic anoyera kumhanya kwemhepo nekukurumidza uye nemazvo zvichienzaniswa neshanduro dzekare.
Nzvimbo dzesainzi dzemuchadenga dzinowanzo shandisa michina iyi pakuita kuyerwa kwenguva dzose kana zvidzidzo zvakadzama kuti zvibatsire kuita kufanotaura kwemamiriro ekunze kwakarurama munzvimbo dzakasiyana-siyana. Mamwe mamiriro ekunze anogona kudzikamisa kuyerwa, asi mamwe magadzirirwo anogona kuitwa kuti matambudziko aya agadziriswe.
MaAnemometers akaonekwa muzana remakore rechi15 uye akaramba achivandudzwa uye achivandudzwa mumakore achangopfuura. MaAnemometers echinyakare, akatanga kugadzirwa pakati pezana remakore rechi19, anoshandisa kurongeka kwedenderedzwa remakapu emhepo akabatana nedata logger. Muma1920, akava matatu, achipa mhinduro inokurumidza uye yakagadzikana inobatsira kuyera mhepo ine simba. MaSonic anemometers ikozvino ndiwo danho rinotevera mukufanotaura mamiriro ekunze, achipa kururama kukuru uye kugadziriswa.
MaSonic anemometers, akatangwa muma1970, anoshandisa mafungu e ultrasonic kuyera kumhanya kwemhepo ipapo ipapo uye kuona kana mafungu eruzha ari kufamba pakati pemasensa maviri ari kukwidziridzwa kana kuti kuderedzwa nemhepo.
Iye zvino dzava kutengeswa zvakanyanya uye dzinoshandiswa munzvimbo dzakasiyana-siyana. Ma "sonic anemometers" ane mativi maviri (kumhanya kwemhepo nekutungamira) anoshandiswa zvakanyanya munzvimbo dzemamiriro ekunze, kutakura zvinhu, ma "wind turbines", ndege, uye kunyangwe pakati pegungwa, achiyangarara pa "weather buoys".
MaSonic anemometers anogona kuita zviyero zvine resolution yenguva yakareba, kazhinji kubva pa20 Hz kusvika 100 Hz, zvichiita kuti zvikwanise kuyera turbulence. Kumhanya uye resolutions muzvikamu izvi zvinobvumira kuyera kwakanyatsojeka. Sonic anemometer ndeimwe yezvishandiso zvitsva zvemamiriro ekunze muzviteshi zvemamiriro ekunze nhasi, uye inonyanya kukosha kupfuura wind vane, iyo inoyera divi remhepo.
Kusiyana neshanduro dzechinyakare, anemometer yesonic haidi zvikamu zvinofamba kuti ishande. Vanoyera nguva inotora kuti kurova kwenzwi kufambe pakati pemasensa maviri. Nguva inotarwa nedaro riri pakati pemasensa aya, uko kumhanya kwenzwi kunoenderana nekupisa, kumanikidzwa uye kusvibiswa kwemhepo kwakadai sekusvibiswa, munyu, guruva kana mhute mumhepo.
Kuti uwane ruzivo rwekumhanya kwemhepo pakati pemasensa, sensa yega yega inoshanda zvakasiyana semutumidziri uye semugamuchiri, saka mapulse anotumirwa pakati pawo kumativi ese ari maviri.
Kumhanya kwekubhururuka kunotsanangurwa zvichienderana nenguva yekurova kwemoyo munzira imwe neimwe; inobata kumhanya kwemhepo, kutungamira uye kona nekuisa ma sensor matatu pama axes matatu akasiyana.
Nzvimbo yeSainzi yeAtmospheric ine ma anemometer gumi nematanhatu esonic, rimwe rawo rinokwanisa kushanda pa100 Hz, maviri acho anokwanisa kushanda pa50 Hz, uye mamwe ese, ayo anonyanya kukwanisa kushanda pa20 Hz, anokurumidza zvakakwana pamabasa mazhinji.
Midziyo miviri ine michina inodzivirira kupisa kwechando inoshandiswa mumamiriro echando. Mizhinji yacho ine zvinhu zvinopinda mu analog, zvichikubvumidza kuwedzera mamwe masensa akadai setembiricha, hunyoro, kumanikidzwa uye magasi ekutevera.
MaSonic anemometers akashandiswa mumapurojekiti akadai seNABMLEX kuyera kumhanya kwemhepo pakukwirira kwakasiyana, uye Cityflux yakatora zviyero zvakasiyana munzvimbo dzakasiyana dzeguta.
Chikwata cheCityFlux project, chinoongorora kusvibiswa kwemhepo mumaguta, chakati: "Chinangwa chikuru cheCityFlux ndechekudzidza matambudziko ese ari maviri panguva imwe chete nekuyera kuti mhepo ine simba inobvisa sei tunhu tudiki kubva mu 'canyons' dzemumigwagwa yeguta nekukurumidza. Mhepo iri pamusoro padzo ndipo patinogara uye patinofema. Nzvimbo inogona kupeperetswa nemhepo."
MaSonic anemometers ndiwo matsva makuru ekuyera kumhanya kwemhepo, zvichivandudza kururama kwekufanotaura kwemamiriro ekunze uye hazvibatanidzwi nemamiriro ezvinhu akaipa akadai semvura zhinji inogona kukonzera matambudziko nemidziyo yechinyakare.
Ruzivo rwakarurama rwekumhanya kwemhepo runotibatsira kunzwisisa mamiriro ekunze ari kuuya uye kugadzirira hupenyu hwezuva nezuva nebasa.
