Zofunikira Zowunikira Ma Hydrological ku Philippines ndi Ubwino wa Radar Technology
Monga dziko la zisumbu ku Southeast Asia lopangidwa ndi zisumbu zoposa 7,000, dziko la Philippines lili ndi malo ovuta okhala ndi mitsinje yambiri ndipo nthawi zonse limayang'anizana ndi chiwopsezo cha chimphepo ndi mvula yamkuntho yomwe imayambitsa kusefukira kwamadzi. Malinga ndi deta ya Banki Yadziko Lonse, kuwonongeka kwachuma kwapachaka chifukwa cha kusefukira kwa madzi ku Philippines kumafika mazana mamiliyoni a madola aku US, zomwe zimapangitsa kuwunika kolondola kwamadzi kukhala gawo lofunikira kwambiri pakupewa komanso kuchepetsa ngozi zapadziko lonse.
Ukadaulo wa sensa ya radar, yokhala ndi kuthekera kwake koyezera osalumikizana, yakhala njira yabwino yothetsera zovuta zowunikira ma hydrological ku Philippines. Kutengera mfundo zoyendera mafunde amagetsi, ukadaulo uwu umapereka maubwino atatu oyambira: 1) kuyeza kolondola kwambiri kwa millimeter; 2) kusinthika kwamphamvu kwachilengedwe koyenera nyengo yotentha ya Philippines yotentha komanso chinyezi; ndi 3) zofunikira zosamalira zochepa, kuchepetsa kwambiri kusungirako zida kumadera akutali.
Mwaukadaulo, masensa a radar omwe amagwiritsidwa ntchito ku Philippines makamaka amagwira ntchito m'magulu awiri: K-band (24GHz) ndi ma frequency 80GHz. K-band radar imapereka zabwino zamtengo wapatali zoyenera kutumizidwa kwakukulu, pomwe radar ya 80GHz imachita bwino kwambiri m'malo ovuta.
Ma Radar Level Monitoring Applications mu Machenjezo a Chigumula
Machenjezo ochenjeza za kusefukira kwa madzi ku Philippines amagwiritsa ntchito njira zowunikira ma radar monga zida zazikulu zaukadaulo. Mu pulojekiti yayikulu ya 2019, boma la Philippines lidatumiza njira yowunikira kuchuluka kwa madzi pogwiritsa ntchito ukadaulo wotumizira mawayilesi m'mitsinje ikuluikulu 18. Dongosololi likuwonetsa zopindulitsa zazikulu m'malo amapiri ndi mvula yamkuntho: kulowa mwamphamvu kwamawayilesi osakhudzidwa ndi kuwonongeka kwa zomangamanga zama foni; Kugwiritsa ntchito mphamvu zochepa kwambiri kumapangitsa kuti munthu azigwira ntchito nthawi yayitali ndi mphamvu yadzuwa yokha. Deta yogwira ntchito ikuwonetsa kuti dongosololi limakwaniritsa kukhazikika kwa kutumiza kwa data 99.7%.
Yankho lina lopambana limagwiritsa ntchito ukadaulo wa K-band planar radar womwe umatha kuyeza mulingo wamadzi nthawi imodzi, kuthamanga kwamadzi, komanso kuwerengera kutulutsa. Kuthekera koyang'anira kogwira ntchito kosiyanasiyanaku kumakhala kofunikira kwambiri pakuchenjeza za kusefukira kwa madzi. Masensa a radar a dongosololi amakhala ndi miyeso yayikulu ya 30-70 metres kulondola kwa millimeter, ndipo muyeso wosalumikizana umapewa zovuta za masensa achikhalidwe kuwonongeka kapena kutsekedwa ndi madzi osefukira.
Bungwe la National Disaster Risk Reduction and Management Council assessment linanena kuti atakhazikitsa njira zowunikira ma radar, nthawi yayitali yochenjeza za kusefukira kwamadzi idakwera kuchokera pa 2 mpaka maola 6, ndikuyenda bwino kwa anthu othawa kwawo komanso chitetezo cha katundu chikuwonjezeka ndi 35% ndi 28% motsatana.
Radar Level Monitoring mu Urban Drainage and Wastewater Treatment
Mu Metro Manila's town drainage monitoring system, 80GHz FMCW radar level gauge ikuwonetsa ntchito yabwino kwambiri. Zopangidwira makamaka kumadera ovuta a m'matauni, zipangizozi zimakhala ndi: mawonekedwe osakanikirana oyenera kuyika mu mapaipi opapatiza ndi zitsime zoyendera; chitetezo chokwanira kwambiri chomwe chimatsimikizira kugwira ntchito pamvula yamphamvu komanso kusefukira kwamadzi; ndi ma module opanda zingwe omwe amathandizira kasinthidwe kaukadaulo wakutali. Deta yam'munda ikuwonetsa magwiridwe antchito abwino kwambiri polowera mipope wamba ya m'tauni monga nthunzi, thovu, ndi zolimba zoyimitsidwa, ndikusunga muyeso wolondola mkati mwa ± 3mm.
Pakugwiritsa ntchito madzi otayira, ma radar apamwamba kwambiri a FMCW amapambana pakuwunika kwa tanki ya sedimentation. Mapangidwe a mtengo wokhazikika amachepetsa bwino kusokoneza kusokoneza kwa chizindikiro kuchokera ku zolimba zoyimitsidwa; ngodya zopapatiza kwambiri zimateteza ma siginecha abodza kuchokera pamakoma a thanki; ndi zotuluka zodziwika bwino zimalumikizana mwachindunji ndi mapampu ochotsa matope kuti aziwongolera zokha. Deta yogwira ntchito ikuwonetsa kuti milingo ya radar imapangitsa kuti zinyalala zizigwira ntchito bwino ndi 20% pomwe zikupulumutsa ndalama zambiri pachaka pantchito yokonza.
Maphunziro a Radar Level Measurement Case
M'mafamu osungira mafuta, ma gauge owongolera a radar amapereka mayankho ofunikira pakuwunika kwamadzi kowopsa. Pokhala ndi tinyanga tamitengo yoyikidwa mu mapaipi aafupi kuti apewe kusokonezedwa kwa thanki ya echo, zida izi zimakwaniritsa kulondola kwa miyeso yamalonda. Kapangidwe kawo kotetezeka kokhazikika kamagwirizana ndi miyezo yapadziko lonse lapansi yotsimikizira kuphulika, ndiukadaulo wodziwunikira nthawi ndi nthawi kuyang'ana momwe zida ziliri kuti zithandizire chitetezo chogwira ntchito. Malipoti akuwonetsa kuti milingo ya radar imachepetsa kwambiri mikangano yoyezera ndipo imabweretsa phindu lalikulu pazachuma kudzera mu kasamalidwe kolondola ka zinthu.
M'makampani opanga mankhwala, ma radar apamwamba kwambiri a FMCW amathetsa zovuta zamadzimadzi zomwe zimawononga kwambiri komanso zosasunthika. Zopangidwa ndi zida zolimbana ndi dzimbiri, ma siginecha awo othamanga kwambiri amapereka kulowa mwamphamvu kosakhudzidwa ndi kusokoneza kwa nthunzi, pomwe kusanja kopitilira muyeso kumapangitsa kusintha kwa mphindi. Deta yophatikizira zomera ikuwonetsa ma radar amawongolera kwambiri kukhazikika kwa matanki ndikuchotsa kusokoneza kwa kupanga chifukwa cha zolakwika zoyezera.
Kugwiritsa Ntchito Kuwunika kwa Madzi mu Ulimi Wothirira ndi Hydropower
Mu njira yayikulu yothirira yothirira ku North Luzon, miyeso yamadzi ya radar yosalumikizana imayang'anira mfundo zazikulu m'ngalande zazikulu. Pogwiritsa ntchito mafupipafupi a K-band okhala ndi ngodya zing'onozing'ono zamitengo kuti apewe zowunikira, chitetezo cha IP68 m'malo ovuta, komanso mphamvu yadzuwa kumadera akutali, oyang'anira ulimi wothirira akuti 95% yogawa madzi ndiyolondola komanso kuchuluka kwa 15% kwa zokolola za mpunga.
Pamalo opangira magetsi opangira magetsi opangira madzi, ma geji a radar a 80GHz amayang'anira kuchuluka kwa madamu akutsogolo kwa 40-mita ndi ± 2mm kulondola, kutumiza deta yeniyeni kudzera pa 4-20mA siginecha kumayendedwe owongolera mbewu. Zolemba zogwirira ntchito zikuwonetsa kuti ma radar gauge amathandizira kukonza mphamvu zopangira magetsi ndi 8% ndikuwonetsetsa kuti kusefukira kwamadzi kumayenda bwino.
