Munguva yekuchinja kwemamiriro ekunze kwakanyanya, nzira dzechinyakare dzekuongorora huwandu hwemvura dzinongoyera "hurefu" sekuyera hurefu hwemunhu, nepo Doppler hydrological radar ichiteerera "kurova kwemoyo" wemvura - ichipa ruzivo rwakasiyana-siyana rwekudzora mafashamo uye manejimendi ezviwanikwa zvemvura.
Munguva yemafashamo, chatinofanira kuziva zvakanyanya hachisi chete "kuti mvura yakakwira sei" asiwo "kuti inoyerera nekukurumidza sei." Ma sensor emvura echinyakare akafanana nemaruler akanyarara, anongonyora shanduko dzenhamba dzakamira, nepo Doppler hydrological radar ichiita semuongorori anonyatsogona mutauro wemvura, achidudzira kudzika kwemvura nekumhanya kwekuyerera, achivandudza data rechikamu chimwe chete kusvika pakunzwisisa kwenzvimbo nepanguva.
Mashiripiti eFizikisi: Kana Mafungu eRadar Akasangana Nemvura Inoyerera
Musimboti mukuru we tekinoroji iyi unobva pane zvakaitika muna 1842 nemusayendisiti wekuAustria Christian Doppler—Doppler Effect. Chiitiko chinozivikanwa chesiren yeamburenzi inosimuka munzwi painoswedera uye ichidonha painodzikira ndiyo acoustic version yemhedzisiro iyi.
Kana mafungu eradar achirova pamusoro pemvura inoyerera, hurukuro chaiyo inoitika:
- Kuona Kumhanya: Zvidimbu zvakasungirirwa uye zvivakwa zvisina kugadzikana mukuyerera kwemvura zvinoratidza mafungu eradar, zvichikonzera kuchinja kwemafrequency. Nekuyera "kuchinja kwemafrequency" uku, sisitimu inoverenga nemazvo kumhanya kwekuyerera kwemvura pamusoro.
- Kuyerwa Kwemazinga Emvura: Panguva imwe chete, radar inoyera nguva yekufamba kwemwaranzi kuti iwane kukwirira kwemazinga emvura nemazvo
- Kuverenga Kuyerera: Pamwe chete nemamodeli ejometri akapatsanurwa (akawanikwa kuburikidza neongororo dzisati dzaitwa kana kuskena maumbirwo erwizi/chiteshi nelaser), sisitimu iyi inoverenga mwero wekuyerera kwemvura (mamita ekubikira/sekondi) munguva chaiyo.
Kubudirira Kwetekinoroji: Kubva Pakuyera Pfungwa Kusvika Pakunzwisisa Kwakarongeka
1. Kutarisa Kusingasanganisike Nevamwe
- Yakaiswa pamusoro pemvura mamita 2-10, ichidzivirira zvachose kukuvara kwemafashamo
- Hapana zvinhu zvakanyudzwa mumvura, zvisingakanganiswi nedota, chando, kana zvisikwa zvemumvura
- Kushanda kwakasimba kunyangwe panguva yemafashamo ane marara akawanda anoyangarara
2. Zviyero zveData Zvisati Zvamboitika
- Nzira dzechinyakare dzinoda kuiswa kwakasiyana kwemageji emvura nemamita ekuyerera, nekubatanidza data nemaoko.
- Doppler radar inopa ruzivo rwakabatanidzwa rwechokwadi panguva chaiyo:
- Kururama kwehuwandu hwemvura: ± 3 mm
- Kururama kwekumhanya kwekuyerera: ± 0.01 m/s
- Kurongeka kwehuwandu hwekuyerera kwemvura: zviri nani pane ± 5% (mushure mekuongororwa kwemunda)
3. Masisitimu Akangwara Ekunyevera Mafashamo
Muchirongwa cheNetherlands che "Room for the River", maDoppler radar networks akawana fungidziro chaiyo yehuwandu hwemafashamo maawa 3-6 pachine nguva. Sisitimu iyi inofanotaura kwete chete kuti "mvura ichakwira zvakadii" asiwo "kuti mafashamo achasvika riini mumaguta ari pasi perwizi," zvichitora nguva yakakosha yekubuda uye kubuda kwemvura.
Maitiro Ekushandisa: Kubva kuNzizi dzeMakomo Kuenda kuMigero yeMaguta
Kugadzirisa Magetsi Emagetsi
Zvivakwa zvemagetsi zvinoshandisa mvura muSwiss Alps zvinoshandisa Doppler radar kuti zviongorore kupinda kwemagetsi panguva chaiyo, zvichigadzirisa zvirongwa zvekugadzira magetsi nenzira inochinja-chinja. Data ra2022 rinoratidza kuti kuburikidza nekufanotaura kwakarurama kwekunyunguduka kwemvura, chimwe chivakwa chemagetsi chakawedzera kugadzirwa kwegore negore ne4.2%, zvakaenzana nekuderedza matani 2000 eCO₂ emissions.
Kutarisira Sisitimu Yekudhonza Mvura Mumaguta
Nzvimbo yeTokyo Metropolitan yakaisa nzvimbo dzekutarisa maDoppler makumi masere nenomwe, zvichigadzira network yeradar yemvura ine huwandu hwakanyanya pasi rose mumaguta. Sisitimu iyi inoona miganhu yemvura panguva chaiyo uye inogadzirisa otomatiki magedhi emvura panguva yemvura inonaya, zvichibudirira kudzivirira zviitiko zvitatu zvikuru zvemafashamo muna 2023.
Kuronga Kudiridza Kwekurima Kwakanyatsonaka
Matunhu ekudiridza ari muCentral Valley muCalifornia anobatanidza Doppler radar nemasensa ekunyorovesa ivhu kuti pave nekudiridza kwakachenjera kwe "flow-based allocation". Sisitimu iyi inogadzirisa maburi emagedhi emvura zvichienderana nehuwandu hwekuyerera kwemvura panguva chaiyo, zvichichengetedza mamiriyoni makumi matatu nemanomwe ema cubic metres emvura muna 2023.
Kutarisa Kuyerera Kwezvakatipoteredza
Muchirongwa chekudzoreredza nharaunda yeRwizi rweColorado, Doppler radar inoramba ichitarisa kuyerera kushoma kwenzvimbo yehove kuti hove dzifambe. Kana kuyerera kwayo kwaderera, sisitimu yacho inogadzirisa otomatiki kuburitswa kwehove dziri mudura remvura, zvichibudirira kuchengetedza mwaka wekubereka we2022 wehumpback chub iri munjodzi.
Kushanduka Kwetekinoroji: Kubva Pamwe Chete Kuenda Kuhungwaru Hwenetwork
Masisitimu eradar emvura eDoppler echizvarwa chitsva ari kukura munzira nhatu:
- Kuziva Kwakabatana: Ma "radar nodes" akawanda anogadzira "hydrological neural networks" kuburikidza ne "5G/Mesh networking", ichitevera kupararira kwemafungu emafashamo mumigero.
- Kuongorora Kwakawedzerwa kweAI: Maalgorithms ekudzidza kwemuchina anoona maumbirwo ekuyerera kwemvura (senge mavortice, kuyerera kwechipiri) kubva kuDoppler spectra, zvichipa mamodheru ekugovera kumhanya akanyatsojeka.
- Kusanganiswa kweMasensor Akawanda: Kubatanidzwa neradar yemamiriro ekunze, magauge emvura, uye data resatellite kunovaka masisitimu e "hydrological monitoring akabatanidzwa" e "air-space-ground" akangwara.
Matambudziko Neramangwana: Kana Tekinoroji Ikasangana Nezvinhu Zvakaoma Zvikuru
Pasinei nekufambira mberi kwetekinoroji, radar yemvura yeDoppler ichiri kutarisana nematambudziko ezvakatipoteredza:
- Mvura ine madhaka akawanda ine huwandu hwakawanda hwemadhaka anogona kukanganisa kunaka kwechiratidzo
- Nzvimbo dzakaputirwa nemiti yemumvura dzinoda maalgorithms akakosha ekugadzirisa zviratidzo
- Kuyerera kwemvura ine aizi kunoda nzira dzakasiyana dzekuyera kuyerera kwemvura dzine zvikamu zviviri.
Mapoka eR&D epasi rose ari kukura:
- Masisitimu eradar ane mabhendi akawanda (Ku-band pamwe chete neC-band) achichinjika kumamiriro akasiyana emhando yemvura
- Tekinoroji yePolarimetric Doppler inosiyanisa mafungu epamusoro kubva pasi pemvura kumhanya kwekuyerera
- Mamodule eEdge computing anopedzisa kugadzirisa masaini akaomarara pamucheto wemudziyo, zvichideredza zvinodiwa pakutumira data
Mhedziso: Kubva paKutarisa kusvika paKunzwisisa, Kubva paData kusvika paUchenjeri
Doppler hydrological radar haingomiriri kufambira mberi kwezvishandiso zvekuyera chete asi shanduko yekufunga—kubva pakuona mvura se“chinhu chinofanira kuyerwa” kusvika pakuinzwisisa se“system inorarama ine maitiro akaomarara.” Inoita kuti kuyerera kusingaonekwe kuonekwe uye kufanotaura kwemvura kusinganzwisisike kuve kwakarurama.
Mumamiriro ezvinhu anhasi ezviitiko zvakanyanya zvemvura, tekinoroji iyi iri kuva nzira yakakosha yekubatana kwevanhu nemvura. Kuchinja kwega kwega kwefrequency kwakatorwa, data rega rega rinogadzirwa respeed-water level rinomiririra kuyedza kwehungwaru hwevanhu kududzira mutauro wechisikigo.
Nguva inotevera paunoona rwizi, yeuka: pane imwe nzvimbo pamusoro pemvura, mafungu asingaonekwe eradar ari kuita mamiriyoni e "hurukuro" pasekondi imwe neimwe nemvura inoyerera. Mhedzisiro yehurukuro idzi iri kutibatsira kuvaka remangwana remvura rakachengeteka uye rinogara kwenguva refu.
Seti yakakwana yemaseva nesoftware isina waya module, inotsigira RS485 GPRS /4g/WIFI/LORA/LORAWAN
Kuti uwane mamwe masensa eradar yemvura ruzivo,
