Akupanga Anemometer

Malo okwerera nyengo ndi pulojekiti yotchuka yoyesera zowunikira zosiyanasiyana zachilengedwe, ndipo kapu yosavuta ya anemometer ndi vane nyengo nthawi zambiri amasankhidwa kuti adziwe kuthamanga kwa mphepo ndi komwe akupita.Kwa Jianjia Ma's QingStation, adaganiza zopanga mtundu wina wa sensa yamphepo: ultrasonic anemometer.
Akupanga anemometers alibe mbali zosuntha, koma malonda ndi kuwonjezeka kwakukulu kwa zovuta zamagetsi.Amagwira ntchito poyesa nthawi yomwe imatengera kuti phokoso la ultrasonic liwonekere kwa wolandira patali kwambiri.Mayendedwe amphepo amatha kuwerengedwa powerenga liwiro kuchokera pawiri awiri akupanga masensa perpendicular kwa wina ndi mzake ndi kugwiritsa ntchito trigonometry yosavuta.Kugwira ntchito moyenera kwa akupanga anemometer kumafuna kupangidwa mosamala kwa amplifier ya analogi pamapeto olandila komanso kukonza ma siginecha ambiri kuti muchotse chizindikiro cholondola kuchokera ku ma echoes achiwiri, kuchulukitsa kachulukidwe, ndi phokoso lonse lobwera chifukwa cha chilengedwe.Mapangidwe ndi machitidwe oyesera amalembedwa bwino.Popeza [Jianjia] sanathe kugwiritsa ntchito ngalande yamphepoyo poyesa ndi kuyezetsa, kwa kanthaŵi anaika makina opimitsira magetsi padenga la galimoto yake n’kunyamuka.Zotsatira zake ndizofanana ndi liwiro la GPS lagalimoto, koma mokwera pang'ono.Izi zitha kukhala chifukwa cha zolakwika zowerengera kapena zinthu zakunja monga kusokonekera kwa mphepo kapena kayendedwe ka mpweya kuchokera pamagalimoto oyeserera kapena kuchuluka kwa magalimoto pamsewu.
Zomverera zina zimaphatikizapo masensa a mvula, zowunikira kuwala, zowunikira kuwala ndi BME280 poyeza kuthamanga kwa mpweya, chinyezi ndi kutentha.Jianjia akufuna kugwiritsa ntchito QingStation m'boti lodziyimira palokha, kotero adawonjezeranso IMU, kampasi, GPS, ndi maikolofoni kuti azimveka mozungulira.
Chifukwa cha kupita patsogolo kwa masensa, zamagetsi, ndi ukadaulo wa prototyping, kupanga malo ochitirako nyengo ndikosavuta kuposa kale.Kupezeka kwa ma module a netiweki otsika mtengo kumatipangitsa kuwonetsetsa kuti zida za IoT zitha kutumiza zidziwitso zawo kumalo osungira anthu, kupatsa madera amderali ndi data yoyenera yanyengo mdera lawo.
Manolis Nikiforakis akuyesera kupanga Pyramid ya Weather, chipangizo chokhazikika, chokhazikika, chopanda mphamvu, chopanda mphamvu komanso cholumikizirana chodziyimira pawokha choyezera nyengo chomwe chimapangidwa kuti chizigwiritsidwa ntchito kwambiri.Nthawi zambiri, malo okwerera nyengo amakhala ndi masensa omwe amayesa kutentha, kuthamanga, chinyezi, kuthamanga kwa mphepo ndi mvula.Ngakhale zambiri mwazigawozi zimatha kuyezedwa pogwiritsa ntchito masensa amtundu wokhazikika, kudziwa liwiro la mphepo, komwe akupita, ndi mvula nthawi zambiri zimafunikira mtundu wina wa chipangizo chamagetsi.
Mapangidwe a masensa oterewa ndi ovuta komanso ovuta.Pokonzekera kutumizidwa kwakukulu, muyeneranso kuwonetsetsa kuti ndizotsika mtengo, zosavuta kuziyika, ndipo sizifunikira kukonzanso pafupipafupi.Kuthetsa mavuto onsewa kungapangitse kuti pamangidwe masiteshoni odalirika komanso otsika mtengo kwambiri, omwe akanatha kuikidwa m’madera ambiri akutali.
Manolis ali ndi malingaliro amomwe angathetsere mavutowa.Akukonzekera kulanda liwiro la mphepo ndi mayendedwe kuchokera ku accelerometer, gyroscope ndi kampasi mu inertial sensor unit (IMU) (mwina MPU-9150).Ndondomekoyi ndikutsata kayendetsedwe ka sensa ya IMU pamene imayenda momasuka pa chingwe, ngati pendulum.Wawerengera pa chopukutira ndipo akuwoneka kuti ali ndi chidaliro kuti apereka zotsatira zomwe amafunikira poyesa chithunzicho.Kuzindikira mvula kudzachitika pogwiritsa ntchito masensa opangira mphamvu pogwiritsa ntchito sensa yodzipatulira monga MPR121 kapena ntchito yolumikizidwa mu ESP32.Mapangidwe ndi malo a ma elekitirodi ndi ofunika kwambiri poyezera mvula moyenera pozindikira madontho amvula.Kukula, mawonekedwe ndi kugawa kwa kulemera kwa nyumba yomwe sensor imayikidwa ndizovuta kwambiri chifukwa zimakhudza mtundu, kuthetsa ndi kulondola kwa chida.Manolis akugwira ntchito pamalingaliro angapo opangira omwe akufuna kuyesa asanasankhe ngati malo onse anyengo adzakhala mkati mwa nyumba zozungulira kapena masensa mkati.
Chifukwa cha chidwi chake pa zanyengo, [Karl] anamanga siteshoni yanyengo.Chatsopano kwambiri mwa izi ndi ultrasonic wind sensor, yomwe imagwiritsa ntchito nthawi yowuluka ya ma ultrasonic pulses kuti adziwe kuthamanga kwa mphepo.
Sensa ya Carla imagwiritsa ntchito ma transducers anayi akupanga, olunjika kumpoto, kum'mwera, kum'mawa ndi kumadzulo, kuti azindikire kuthamanga kwa mphepo.Poyesa nthawi yomwe imatengera kuti ultrasonic pulse iyende pakati pa masensa m'chipinda ndikuchotsa miyeso yamunda, timapeza nthawi yowuluka pa axis iliyonse motero liwiro la mphepo.
Ichi ndi chionetsero chochititsa chidwi cha mayankho a uinjiniya, limodzi ndi lipoti latsatanetsatane latsatanetsatane.
