Zvinodiwa paKutarisa Mvura muPhilippines uye Mabhenefiti eTekinoroji yeRadar
Senyika ine zvitsuwa zvakawanda muSoutheast Asia ine zvitsuwa zvinopfuura 7,000, Philippines ine nzvimbo dzakaoma dzine nzizi dzakawanda uye inotarisana nekutyisidzirwa nguva dzose nemadutu nemvura inonaya inokonzera mafashamo. Sekureva kwedata reWorld Bank, kurasikirwa kwehupfumi pagore kunokonzerwa nemafashamo muPhilippines kunosvika mazana emamiriyoni emadhora ekuAmerica, zvichiita kuti kutarisa mvura nemazvo kuve chinhu chakakosha mukudzivirira njodzi dzenyika nekuderedza njodzi.
Tekinoroji yekunzwa level radar, ine kugona kwayo kuyera pasina kubatwa, yave mhinduro yakanaka kune matambudziko ekutarisa mvura muPhilippines. Zvichibva pamisimboti yekuyera mafungu emagetsi, tekinoroji iyi inopa zvakanakira zvitatu zvikuru: 1) kuyerwa kwakanyatsojeka kwe millimeter; 2) kuchinjika kwakasimba kwezvakatipoteredza kwakakodzera mamiriro ekunze ekupisa kwakanyanya uye hunyoro muPhilippines; uye 3) zvinodiwa zvishoma zvekugadzirisa, zvichideredza zvakanyanya kuwanda kwekuchengetedza michina munzvimbo dziri kure.
Muchokwadi, masensa eradar level anoshandiswa muPhilippines anoshanda zvakanyanya mumabhendi maviri efrequency: K-band (24GHz) uye high-frequency 80GHz. K-band radar inopa zvakanakira mutengo wakakodzera kushandiswa kukuru, nepo 80GHz radar ichishanda zvakanaka munzvimbo dzakaoma.
Mashandisirwo Ekutarisa Radar Level muMasisitimu Ekunyevera Mafashamo
Sangano renyika rePhilippines rekuzivisa nezvemafashamo rinoshandisa masisitimu ekutarisa mazinga eradar sezvikamu zvikuru zvehunyanzvi. Muchirongwa chikuru cha2019, hurumende yePhilippines yakaisa network yekutarisa mazinga emvura yakavakirwa patekinoroji yekutumira redhiyo mumahombekombe makuru gumi nemasere enzizi. Sisitimu iyi inoratidza zvakanakira zvikuru munzvimbo dzine makomo uye mamiriro emvura: kupinda kwemafungu eredhiyo kwakasimba pasina kukanganiswa nekukuvara kwezvivakwa zvekutaurirana; kushandiswa kwesimba kushoma kwazvo zvichiita kuti ishande kwenguva refu nesimba rezuva chete. Ruzivo rwekushanda runoratidza kuti sisitimu iyi ine 99.7% yekugadzikana kwekutumira data.
Imwe mhinduro inoshanda inoshandisa tekinoroji yeK-band planar radar inokwanisa kuyera huwandu hwemvura, kumhanya kwekuyerera kwemvura pamusoro, uye kuverenga kubuda kwayo panguva imwe chete. Kugona uku kwekutarisa kwakawanda kunobatsira zvikuru pakunyevera nezvemafashamo. Masensa eradar esystem iyi ane nzvimbo dzakakura dzekuyera dzinosvika 30-70 metres uye akarurama padanho remamirimita, uye kuyerwa kusingabatanidzi mvura kunodzivirira matambudziko ekuti masensa echinyakare akuvadzwe kana kuvharwa nemvura yemafashamo.
Ongororo yeNational Disaster Risk Reduction and Management Council inoti mushure mekushandisa nzira dzekutarisa mazinga eradar, avhareji yenguva yekunyevera mafashamo yakawedzera kubva pamaawa maviri kusvika matanhatu, nekushanda zvakanaka kwekubuda uye mwero wekuchengetedza pfuma uchiwedzera ne35% uye 28% zvichiteerana.
Kutarisa Radar Level muMadhoni Emvura uye Kurapa Mvura Yakasviba
Muhurongwa hwekutarisa mvura iri mumaguta eMetro Manila, magauge eradar e80GHz FMCW anoratidza kushanda kwakanaka. Akagadzirirwa nzvimbo dzakaoma dzemaguta, zvishandiso izvi zvine: chimiro chakasimba chakakodzera kuiswa mumapombi emvura akamanikana uye matsime ekuongorora; chiyero chepamusoro chekudzivirira chinoratidza kushanda panguva yemvura zhinji nemafashamo; uye mamodule asina waya anogonesa mainjiniya ari kure. Ruzivo rwemunda runoratidza kushanda kwakanaka kunopinda mumamiriro ezvinhu akafanana emapombi emvura ari mumaguta akadai seutsi, furo, uye zvinhu zvakasimba zvakamiswa, zvichichengetedza kurongeka kwekuyera mukati me ±3mm.
Mukushandiswa kwekuchenesa mvura yakasviba, magauge eradar eFMCW anomhanya zvakanyanya mukutarisa matangi emvura yakasviba. Dhizaini yedanda rakatarisana inoderedza kupindira kwechiratidzo kubva kuzvinhu zvakasimba zvakasungirirwa; makona akamanikana edanda anodzivirira zviratidzo zvenhema kubva kumadziro etangi; uye zvinobuda zvechiratidzo zvinoenderana zvakananga nemapombi ekubvisa tsvina kuti zvidzore otomatiki zvizere. Ruzivo rwekushanda runoratidza kuti magauge eradar anowedzera kushanda zvakanaka kwekurapa tsvina ne20% ukuwo achichengetedza mari yakawanda pagore mukugadzirisa vashandi.
Zvidzidzo zveKuyera Radar Level yeIndasitiri
Mumatangi ekuchengetera mafuta, magauge eradar anotungamirwa anopa mhinduro dzakakosha dzekutarisa mvura ine njodzi. Aine maantenna akatarisana akaiswa mumapombi mapfupi kudzivirira kupindirana kwematangi pamadziro, zvishandiso izvi zvinoita kuti kuyerwa kwekuchinjana kwekutengeserana kuve kwakarurama. Dhizaini yavo yakachengeteka inosangana nezvinodiwa zvepasi rose zvisingaputike, netekinoroji yekuzviongorora nguva nenguva ichiongorora mamiriro emidziyo kuti iwedzere kuchengetedzeka kwekushanda. Mishumo inoratidza kuti magauge eradar anoderedza zvikuru kusawirirana kwekuyera uye anounza mabhenefiti makuru ehupfumi kuburikidza nekutarisira zvinhu nenzira chaiyo.
Muindasitiri yemakemikari, magauge eradar eFMCW ane frequency yakakwira anobudirira kugadzirisa matambudziko ekuyera ezvinwiwa zvinopisa zvakanyanya uye zvinoputika. Zvakagadzirwa nezvinhu zvisingapindi ngura, masaini avo eradar ane frequency yakakwira anopa kupinda kwakasimba pasina kukanganiswa nekukanganiswa kwemhepo, nepo resolution yepamusoro-soro inobata shanduko dzemazinga emaminetsi. Ruzivo rwekubatanidza michina runoratidza kuti magauge eradar anovandudza zvakanyanya kugadzikana kwekutonga kwemazinga etangi uye anobvisa kukanganiswa kwekugadzirwa kubva mukukanganisa kwekuyera.
Mashandisirwo Ekutarisa Mwero Wemvura Mukurima Kwekudiridza uye Kugadzira Simba reMadziva
Munzira huru yekudiridza yeNorth Luzon, nzira dzekuongorora huwandu hwemvura dzinoshandiswa neradar dzinoongorora ma key nodes ari mumigero mikuru. Ichishandisa frequency yeK-band ine makona madiki emwenje kudzivirira kupenya kwemvura, dziviriro yeIP68 munzvimbo dzakaoma dzekunze, uye simba rezuva kunzvimbo dziri kure, hofisi yekudiridza inotaura kuti mvura inoparadzirwa ne95% uye kuwedzera kwemupunga ne15%.
Pachishandiso chekuburitsa simba remagetsi chetangi guru remagetsi, magauge emvura e80GHz radar anotarisa mazinga emvura yemudhamu ane 40-meter range uye ±2mm akarurama, achitumira data renguva chaiyo kuburikidza nemasaini e4-20mA kumasystem ekudzora tangi. Zvinyorwa zvekushanda zvinoratidza kuti magauge eradar anobatsira kuvandudza mashandiro ekugadzira magetsi ne8% ukuwo achivimbisa kuchengetedzeka kwemafashamo.
