Ultrasonic Anemometer

Zviteshi zvemamiriro ekunze ipurojekiti yakakurumbira yekuyedza akasiyana masensa emamiriro ekunze, uye kapu yakapusa anemometer uye mamiriro ekunze zvinowanzosarudzwa kuona kumhanya kwemhepo uye kwairi.YeJianjia Ma's QingStation, akafunga kuvaka imwe mhando yemhepo sensor: an ultrasonic anemometer.
Ultrasonic anemometers haina zvikamu zvinofamba, asi kutengeserana ndiko kuwedzera kukuru kwemagetsi akaoma.Vanoshanda nekuyera nguva inotora kuti ultrasonic sound pulse iratidze kune anogamuchira ari chinhambwe chinozivikanwa.Mhepo inotungamira inogona kuverengerwa nekutora kumhanya kuverenga kubva maviri maviri e ultrasonic sensors perpendicular kune mumwe nemumwe uye kushandisa yakapusa trigonometry.Kushanda kwakaringana kwea ultrasonic anemometer kunoda kungwarira dhizaini yeanalog amplifier pakupera kwekugamuchira uye yakawedzera chiratidzo kugadzirisa kuburitsa iyo chaiyo chiratidzo kubva kune yechipiri echoes, kuwanda kupararira, uye ruzha rwese rwunokonzerwa nenharaunda.Magadzirirwo uye maitiro ekuedza akanyorwa zvakanaka.Sezvo [Jianjia] akanga asingakwanisi kushandisa mugero wemhepo nokuda kwokuedza nokururamisa, kwechinguvana akaisa anemometer padenga remotokari yake ndokuenda.Iko kukosha kunoguma kwakaenzana nekumhanya kweGPS yemota, asi yakakwira zvishoma.Izvi zvinogona kunge zvakakonzerwa nekukanganisa kwekuverenga kana zvinhu zvekunze zvakaita semhepo kana kuvhiringika kwekuyerera kwemhepo kubva kumotokari yekuyedza kana imwe traffic yemumugwagwa.
Mamwe masensa anosanganisira optical rain sensors, light sensors, light sensors uye BME280 yekuyera mhepo, humidity uye tembiricha.Jianjia anoronga kushandisa QingStation muchikepe chinozvimiririra, saka akawedzera IMU, kambasi, GPS, uye maikorofoni kune ambient ruzha.
Nekuda kwekufambira mberi mumasensor, zvemagetsi, uye prototyping tekinoroji, kuvaka chiteshi chemamiriro ekunze kuri nyore kupfuura nakare kose.Kuvepo kwemamodule ane mutengo wakaderera wetiweki kunotibvumira kuona kuti zvishandiso zveIoT izvi zvinogona kuendesa ruzivo rwavo kune veruzhinji dhatabhesi, zvichipa nharaunda dzemunharaunda data yakakodzera yemamiriro ekunze munzvimbo dzavanogara.
Manolis Nikiforakis ari kuyedza kuvaka Weather Pyramid, iyo-yakasimba-nyika, yekuchengetedza-isina, simba- uye kutaurirana-inozvimiririra yemamiriro ekunze ekuyera mudziyo wakagadzirirwa kutumirwa kukuru.Kazhinji, zviteshi zvemamiriro ekunze zvine masensa anoyera tembiricha, kudzvanywa, hunyoro, kumhanya kwemhepo uye kunaya kwemvura.Nepo mazhinji emaparamita aya achigona kuyerwa uchishandisa solid-state sensors, kuona kumhanya kwemhepo, kutungamira, uye kunaya kwemvura kunoda imwe nzira yemagetsi emagetsi.
Magadzirirwo emagetsi akadaro akaoma uye akaoma.Paunenge uchironga kutumirwa kwakakura, iwe zvakare unofanirwa kuve nechokwadi kuti inodhura-inoshanda, iri nyore kuisa, uye haidi kugara ichigadziriswa.Kubvisa matambudziko ose aya kunogona kukonzera kuvakwa kwezviteshi zvemamiriro ekunze zvakavimbika uye zvisingadhuri, izvo zvinozogona kuiswa muhuwandu hwakawanda munzvimbo dziri kure.
Manolis ane mamwe mazano ekugadzirisa matambudziko aya.Anoronga kutora kumhanya kwemhepo uye kutungamira kubva kune accelerometer, gyroscope uye kambasi mune inertial sensor unit (IMU) (zvichida iyo MPU-9150).Chirongwa ndechekutsvaga kufamba kweIMU sensor sezvainozununguka zvakasununguka patambo, sependulum.Akaita mamwe maverengero pane napkin uye anoita seane chivimbo chekuti vanozopa mhedzisiro yaanoda pakuyedza prototype.Kunzwa kunaya kwemvura kuchaitwa uchishandisa capacitive sensors uchishandisa yakazvitsaurira sensor senge MPR121 kana yakavakirwa-mukati kubata basa muESP32.Magadzirirwo uye nzvimbo yemakwara e electrode akakosha zvakanyanya pakuyera kwakaringana kwemvura nekuona madonhwe emvura.Ukuru, chimiro uye kugoverwa kwehuremu kweimba iyo sensor inokwidziridzwa zvakare yakakosha sezvo inokanganisa huwandu, kugadzirisa uye kurongeka kwechiridzwa.Manolis ari kushanda pane akati wandei dhizaini mazano aanoronga kuyedza asati afunga kana iyo mamiriro ekunze ese chiteshi achange ari mukati meimba inotenderera kana ingori masensor mukati.
Nekuda kwekufarira kwake ruzivo rwemamiriro ekunze, [Karl] akavaka chiteshi chemamiriro ekunze.Itsva pane idzi iultrasonic wind sensor, inoshandisa nguva yekubhururuka yema ultrasonic pulses kuona kumhanya kwemhepo.
Carla's sensor inoshandisa ina ultrasonic transducers, yakananga kuchamhembe, kumaodzanyemba, kumabvazuva uye kumadokero, kuona kumhanya kwemhepo.Nekuyera nguva inotora kuti ultrasonic pulse ifambe pakati pema sensors mukamuri uye kubvisa zviyero zvemunda, tinowana nguva yekubhururuka kune imwe neimwe axis uye naizvozvo kumhanya kwemhepo.
Uku kuratidzwa kunoshamisa kweinjiniya mhinduro, inoperekedzwa neinokatyamadza yakadzama dhizaini mushumo.
