Ultrasonic Anemometero

Ibihe byikirere ni umushinga uzwi cyane wo kugerageza hamwe na sensor zitandukanye zidukikije, kandi igikombe cyoroshye anemometero hamwe nikirere gisanzwe cyatoranijwe kugirango hamenyekane umuvuduko wumuyaga nicyerekezo.Kuri QingStation ya Jianjia Ma, yahisemo kubaka ubundi bwoko bwa sensor yumuyaga: anemometero ultrasonic.
Ultrasonic anemometero idafite ibice byimuka, ariko gucuruza ni kwiyongera cyane muburyo bwa elegitoroniki.Bakora mugupima igihe bifata kugirango ultrasonic yijwi ryamajwi kugirango yerekane uwakiriye intera izwi.Icyerekezo cyumuyaga kirashobora kubarwa mugufata ibyasomwe byihuse kuva kubice bibiri bya ultrasonic sensor ya perpendicular kuri mugenzi wawe no gukoresha trigonometrie yoroshye.Gukora neza anemometero ya ultrasonic bisaba gushushanya neza analogi amplifier mugihe cyo kwakirwa no gutunganya ibimenyetso byinshi kugirango ikure ibimenyetso nyabyo mumajwi ya kabiri, gukwirakwiza kwinshi, hamwe n urusaku rwose ruterwa nibidukikije.Igishushanyo nuburyo bwo kugerageza byanditse neza.Kubera ko [Jianjia] atabashaga gukoresha umuyoboro w’umuyaga mu gupima no guhinduranya, yashyizeho anemometero by'agateganyo ku gisenge cy'imodoka ye aragenda.Agaciro kavuyemo kagereranijwe numuvuduko wa GPS yimodoka, ariko hejuru cyane.Ibi birashobora guterwa namakosa yo kubara cyangwa ibintu byo hanze nkumuyaga uhuha cyangwa umuyaga uva mumodoka yikizamini cyangwa izindi nzira zo mumuhanda.
Ibindi byuma bifata ibyuma birimo imvura ya optique, ibyuma byerekana urumuri, ibyuma byerekana urumuri na BME280 yo gupima umuvuduko wumwuka, ubushuhe nubushuhe.Jianjia arateganya gukoresha QingStation mu bwato bwigenga, bityo yongeraho na IMU, compas, GPS, na mikoro kugira ngo yumvikane neza.
Turashimira iterambere muri sensor, electronics, hamwe na tekinoroji ya prototyping, kubaka ikirere cyumuntu byoroshye kuruta mbere hose.Kuboneka kw'ibiciro bidahenze by'urusobe biradufasha kwemeza ko ibyo bikoresho bya IoT bishobora kohereza amakuru yabyo kububiko rusange, bigatanga abaturage baho amakuru yikirere ajyanye nibidukikije.
Manolis Nikiforakis aragerageza kubaka Ikirere Pyramide, leta-ikomeye-yose, idafite-kubungabunga, ingufu-n’itumanaho-byigenga byapima ikirere byateganijwe koherezwa mu buryo bunini.Ubusanzwe, ikirere gifite ibyuma bifata ibyuma bifata ubushyuhe, umuvuduko, ubushuhe, umuvuduko w’umuyaga n’imvura.Mugihe ibyinshi muribi bipimo bishobora gupimwa hifashishijwe ibyuma bifata ibyuma bifata ibyuma byerekana imiterere yumuyaga, icyerekezo, nubushyuhe mubisanzwe bisaba uburyo bumwebumwe bwibikoresho bya elegitoroniki.
Igishushanyo mbonera nkicyo kiragoye kandi kiragoye.Mugihe utegura ibikorwa binini, ugomba kandi kwemeza ko bikoresha amafaranga menshi, byoroshye kuyashiraho, kandi ntibisaba kubitaho kenshi.Kurandura ibyo bibazo byose bishobora gutuma hubakwa sitasiyo y’ikirere yizewe kandi ihendutse, ishobora noneho gushyirwaho ari myinshi mu turere twa kure.
Manolis afite ibitekerezo bimwe byukuntu byakemura ibyo bibazo.Arateganya gufata umuvuduko n'umuyaga uva kuri moteri yihuta, giroskopi na kompas mu gice cya sensor inertial (IMU) (birashoboka ko MPU-9150).Gahunda nugukurikirana urujya n'uruza rwa sensor ya IMU uko izunguruka ku mugozi, nka pendulum.Yakoze ibarwa ku gitambaro kandi asa nuwizeye ko bazatanga ibisubizo akeneye mugihe cyo kugerageza prototype.Kumva imvura bizakorwa hifashishijwe sensor sensor ikoresha sensor yabugenewe nka MPR121 cyangwa ibikorwa byubatswe muri ESP32.Igishushanyo n’aho inzira ya electrode irahambaye cyane mugupima neza imvura mugushakisha imvura.Ingano, imiterere nuburemere bwamazu yubatswemo sensor nayo irakomeye kuko bigira ingaruka kumurongo, gukemura no kumenya neza igikoresho.Manolis arimo gukora ibitekerezo byinshi ateganya kugerageza mbere yo gufata umwanzuro niba ikirere cyose kizaba kiri imbere yinzu izunguruka cyangwa sensor imbere.
Kubera ko ashishikajwe n’iteganyagihe, [Karl] yubatse sitasiyo y’ikirere. Igishya muri ibyo ni sensor yumuyaga ultrasonic, ikoresha igihe cyo guhaguruka kwa puls ultrasonic kugirango umenye umuvuduko wumuyaga.
Rukuruzi ya Carla ikoresha transducers enye, yerekeza mu majyaruguru, mu majyepfo, iburasirazuba no mu burengerazuba, kugira ngo imenye umuvuduko w’umuyaga.Mugupima igihe bifata kugirango ultrasonic pulse igenda hagati ya sensor mucyumba no gukuramo ibipimo byumurima, tubona igihe cyo guhaguruka kuri buri axe bityo umuvuduko wumuyaga.
Nibigaragaza neza ibisubizo byubuhanga, biherekejwe na raporo ishushanyije itangaje.
