Zofunikira pa Kuyang'anira Madzi ku Philippines ndi Ubwino wa Ukadaulo wa Radar
Monga dziko lokhala ndi zilumba zambiri ku Southeast Asia lomwe lili ndi zilumba zoposa 7,000, Philippines ili ndi malo ovuta okhala ndi mitsinje yambiri ndipo ikukumana ndi ziwopsezo zosalekeza chifukwa cha mphepo yamkuntho ndi mvula yamkuntho zomwe zimayambitsa kusefukira kwa madzi. Malinga ndi deta ya World Bank, kutayika kwachuma pachaka chifukwa cha kusefukira kwa madzi ku Philippines kumafika madola mamiliyoni ambiri aku US, zomwe zimapangitsa kuti kuwunika molondola kuchuluka kwa madzi kukhala gawo lofunikira kwambiri pa njira yopewera masoka mdziko lonse komanso kuchepetsa masoka.
Ukadaulo wa sensa ya radar, womwe uli ndi mphamvu yoyezera popanda kukhudzana ndi magetsi, wakhala njira yabwino yothetsera mavuto a kuwunika kwa madzi ku Philippines. Kutengera mfundo zoyendetsera mafunde amagetsi, ukadaulo uwu umapereka zabwino zitatu zazikulu: 1) kuyeza molondola kwambiri kwa millimeter; 2) kusinthasintha kwamphamvu kwa chilengedwe komwe kumayenera nyengo yotentha ya Philippines yokhala ndi kutentha kwakukulu ndi chinyezi; ndi 3) zosowa zochepa zosamalira, zomwe zimachepetsa kwambiri kuchuluka kwa zida zosungira m'madera akutali.
Mwaukadaulo, masensa a radar omwe amagwiritsidwa ntchito ku Philippines amagwira ntchito makamaka m'mabande awiri a pafupipafupi: K-band (24GHz) ndi 80GHz yapamwamba kwambiri. Radar ya K-band imapereka zabwino zogulira zomwe zingagwiritsidwe ntchito pamlingo waukulu, pomwe radar ya 80GHz imagwira ntchito bwino kwambiri m'malo ovuta.
Kugwiritsa Ntchito Kuwunika Ma Radar mu Machitidwe Ochenjeza Kusefukira kwa Madzi
Netiweki yochenjeza za kusefukira kwa madzi ku Philippines imagwiritsa ntchito njira zowunikira mulingo wa radar ngati zigawo zazikulu zaukadaulo. Mu pulojekiti yayikulu ya 2019, boma la Philippines lidayika netiweki yowunikira mulingo wamadzi kutengera ukadaulo wotumizira wailesi m'mabowo akuluakulu 18. Njirayi ikuwonetsa zabwino zazikulu m'malo amapiri ndi nyengo yamkuntho: kulowa kwa mafunde amphamvu a wailesi osakhudzidwa ndi kuwonongeka kwa zomangamanga zamatelefoni; kugwiritsa ntchito mphamvu zochepa kwambiri zomwe zimapangitsa kuti ntchito igwire ntchito kwa nthawi yayitali ndi mphamvu ya dzuwa yokha. Deta yogwirira ntchito ikuwonetsa kuti dongosololi limapeza kukhazikika kwa kutumiza deta ndi 99.7%.
Njira ina yothandiza imagwiritsa ntchito ukadaulo wa radar wa K-band planar womwe umatha kuyeza nthawi yomweyo mulingo wa madzi, liwiro la kuyenda kwa madzi pamwamba, komanso kuwerengera kutuluka kwa madzi. Mphamvu yowunikirayi yogwira ntchito zambiri imakhala yothandiza kwambiri pa machenjezo a kusefukira kwa madzi. Masensa a radar a dongosololi ali ndi miyeso yayikulu ya mamita 30-70 yokhala ndi kulondola kwa mulingo wa mamilimita, ndipo muyeso wosakhudzana ndi madzi umapewa mavuto a masensa achikhalidwe kuwonongeka kapena kutsekedwa ndi madzi osefukira.
Bungwe Loona za Kuchepetsa ndi Kuyang'anira Ngozi za Masoka la Dziko Lonse linanena kuti pambuyo pokhazikitsa njira zowunikira momwe zinthu zilili pa radar, nthawi yochenjeza za kusefukira kwa madzi inakwera kuchoka pa maola awiri mpaka asanu ndi limodzi, ndipo kuchuluka kwa anthu othawa kwawo komanso chitetezo cha katundu kunakwera ndi 35% ndi 28% motsatana.
Kuyang'anira Radar mu Matabwa a Mizinda ndi Kukonza Madzi Otayidwa
Mu dongosolo loyang'anira madzi otuluka m'matauni a Metro Manila, ma radar gauge a 80GHz FMCW akuwonetsa magwiridwe antchito abwino kwambiri. Opangidwira makamaka malo ovuta a m'matauni, zipangizozi zili ndi: kapangidwe kakang'ono koyenera kuyikidwa m'mapaipi opapatiza otuluka ndi zitsime zowunikira; chitetezo chapamwamba chotsimikizira kuti zikugwira ntchito nthawi yamvula yamphamvu ndi kusefukira kwa madzi; ndi ma module opanda zingwe omwe amalola akatswiri akutali kukonza. Deta ya m'munda ikuwonetsa magwiridwe antchito abwino kwambiri kulowa m'malo omwe mapaipi otuluka m'matauni monga nthunzi, thovu, ndi zinthu zolimba zopachikidwa, kusunga kulondola kwa muyeso mkati mwa ±3mm.
Mu ntchito zoyeretsera madzi a zinyalala, ma gauge a FMCW radar level gauge apamwamba kwambiri amapambana pakuwunika thanki yosungiramo madzi. Kapangidwe ka dau lolunjika bwino kamachepetsa kusokoneza kwa ma signal kuchokera ku zinthu zolimba zomwe zayimitsidwa; ma angle opapatiza kwambiri a dauge amaletsa ma signal abodza kuchokera ku makoma a thanki; ndipo ma signal outputs okhazikika amalumikizana mwachindunji ndi ma pumps ochotsa daude kuti azilamulira okha. Deta yogwirira ntchito imasonyeza kuti ma radar level gauge amathandizira kuti daude igwire bwino ntchito ndi 20% pomwe imapanga ndalama zambiri zosungira pachaka pantchito yokonza.
Maphunziro a Milandu Yoyesera Mlingo wa Radar Yamakampani
M'mafamu osungira mafuta, ma guides wave radar level gauges amapereka njira zofunika kwambiri zowunikira madzi oopsa. Pokhala ndi ma antenna olunjika omwe amaikidwa m'mapaipi afupi kuti apewe kusokoneza ma echo a khoma la thanki, zipangizozi zimakwaniritsa kulondola kwa muyeso wa malonda. Kapangidwe kake kotetezeka ka mkati kamakwaniritsa miyezo yapadziko lonse lapansi yolimbana ndi kuphulika, ndi ukadaulo wodziwonera wokha nthawi ndi nthawi umayang'ana momwe zida zilili kuti ziwongolere kwambiri chitetezo cha ntchito. Malipoti akuwonetsa kuti ma radar level gauges amachepetsa kwambiri mikangano yoyezera ndikupanga phindu lalikulu pazachuma kudzera mu kasamalidwe kolondola ka zinthu.
Mu makampani opanga mankhwala, ma gauge a FMCW radar level gauge apamwamba amathetsa mavuto oyezera zakumwa zowononga kwambiri komanso zosakhazikika. Zopangidwa ndi zinthu zosagwira dzimbiri, ma signali awo apamwamba amapereka kulowa kwamphamvu popanda kusokonezedwa ndi nthunzi, pomwe resolution yapamwamba kwambiri imagwira kusintha kwa milingo yaying'ono. Deta yolumikizira zomera ikuwonetsa kuti ma gauge a radar amawongolera kwambiri kukhazikika kwa thanki ndikuchotsa kusokonekera kwa kupanga chifukwa cha zolakwika zoyezera.
Kugwiritsa Ntchito Kuwunika Mlingo wa Madzi mu Ulimi Wothirira ndi Mphamvu ya Madzi
Mu njira yayikulu yothirira ku North Luzon, ma radar gauge amadzi osakhudzana ndi madzi amawunika mfundo zazikulu m'ngalande zazikulu. Pogwiritsa ntchito ma frequency a K-band okhala ndi ngodya zazing'ono kuti apewe kuwunikira kwa embankment, chitetezo cha IP68 ku malo ovuta akunja, ndi mphamvu ya dzuwa kumadera akutali, bungwe lothirira likunena kuti kufalikira kwa madzi ndi 95% komanso kuwonjezeka kwa mpunga ndi 15%.
Pa makina otumizira magetsi ambiri a hydropower, ma radar gauge a 80GHz amawunika kuchuluka kwa madzi a dam forebay okhala ndi mtunda wa mamita 40 ndi kulondola kwa ±2mm, kutumiza deta yeniyeni kudzera mu zizindikiro za 4-20mA ku makina owongolera mafakitale. Zolemba zogwirira ntchito zikuwonetsa kuti ma radar gauge amathandiza kukonza bwino kupanga magetsi ndi 8% pomwe akuwonetsetsa kuti kusefukira kwa madzi kukuyenda bwino.
