Ityala lesicelo seeSensors zeHydrological zeRadar ezisekwe kwiTriple-Parameter eVietnam

—Ulawulo lweZikhukula oluLungileyo kunye noLawulo lweMithombo yamanzi kwiMekong Delta

Imvelaphi

IMekong Delta yaseVietnam yindawo ebalulekileyo kwezolimo nenabantu abaninzi kuMzantsi-mpuma weAsia. Nangona kunjalo, kwiminyaka yakutshanje, utshintsho lwemozulu luye lwandisa imingeni efana nezikhukula, imbalela, kunye nokungena kwamanzi anetyuwa. Iinkqubo zemveli zokubeka esweni amanzi zijongene nokulibaziseka kwedatha, iindleko eziphezulu zokugcinwa, kunye nesidingo seenzwa ezahlukeneyo zeeparameter ezahlukeneyo.

Ngowama-2023, iVietnam Institute of Water Resources (VIWR), ngokubambisana neHo Chi Minh City University of Technology kunye nenkxaso yobugcisa evela kwiGIZ (German Agency for International Cooperation), yavavanya izinzwa ze-hydrological zesizukulwana esilandelayo ezisekelwe kwi-radar kwiphondo laseTien Giang naseKien Giang. Ezi zinzwa zivumela ukujonga ngaxeshanye inqanaba lamanzi, isantya sokuhamba kwamanzi, kunye nemvula, zibonelela ngedatha ebalulekileyo yokulawula izikhukula kunye nokukhuselwa kwenkqubo yendalo kwi-delta.

Iingenelo zobuGcisa eziphambili

1. Ukuhlanganiswa kwabaThathu-kwi-One
   • Isebenzisa amaza eradar ahamba rhoqo angama-24GHz ukulinganisa isantya esisekelwe kwiDoppler (±0.03m/s) kunye nokubonakalisa inqanaba lamanzi kwi-microwave (±1mm), kunye negeyiji yemvula ejikajikayo.
   • Ikhompyutha eyakhelwe ngaphakathi ilungisa iimpazamo ezibangelwa kukungcola okanye ukungcola okudadayo.
2. Uthumelo lwaMandla aphantsi kunye noNxibelelwano olungenazingcingo
   • Isebenza ngamandla elanga nge-LoRaWAN IoT connectivity, ifanelekile kwiindawo ezikude ezingaphandle kwegridi (i-data latency
3. Uyilo Olumelana Neentlekele
   • I-IP68 ilinganiswe ngokuchasene nezivuthuvuthu kunye nokugqwala kwamanzi anetyuwa, kunye nesakhelo sokufakelwa esihlengahlengiswayo ukuze sikwazi ukuziqhelanisa nezikhukula.

Iziphumo zokuphunyezwa

1. Isilumkiso esiphuculweyo seZikhukula kwangethuba
KwiSithili saseChau Thanh (eTien Giang), inethiwekhi yeesensa yaxela kwangaphambili ukuba amanzi aza kuphuma kwiiyure ezi-2 ngaphambi kwexesha ngexesha lokudodobala kwetropiki ngoSeptemba 2023. Izilumkiso ezizenzekelayo zabangela uhlengahlengiso lwesango lokungena kwamanzi elingasentla, zanciphisa iindawo ezikhukuliswe ngamanzi nge-15%.

2. Ulawulo lokungenelela kwetyuwa
EHa Tien (eKien Giang), idatha engaqhelekanga yesantya sokuhamba kwamanzi anetyuwa ngexesha lokungena kwamanzi anetyuwa ngexesha elomileyo incede ukuphucula ukusebenza kwamasango olwandle, yanciphisa ityuwa emanzini okunkcenkceshela ngama-40%.

3. Ukonga iindleko
Xa kuthelekiswa nezinzwa ze-ultrasonic, izixhobo ezisebenzisa i-radar zisuse iingxaki zokuvaleka, nto leyo enciphisa iindleko zokugcinwa konyaka ngama-62%.

Imingeni kunye nezifundo ezifundiweyo

• Uhlengahlengiso lweNdalo: Ukuphazamiseka kokuqala kwesignali yeradar evela kwimithi ye-mangrove kunye neentaka kusonjululwe ngokulungisa ukuphakama kwesensor nokufaka izinto zokuthintela iintaka.
• Ukuhlanganiswa kwedatha: I-middleware yexeshana isetyenziselwe ukuhambelana ne-National Hydro-Meteorological Database (VNMHA) yaseVietnam de kugqitywe ukuhlanganiswa kwe-API epheleleyo.

Ulwandiso Lwexesha Elizayo

UMphathiswa Wezemithombo Yendalo Nokusingqongileyo waseVietnam (i-MONRE) uceba ukusasaza iisensa ezingama-200 kumaphondo ali-13 e-delta ngo-2025, kunye nokudityaniswa kwe-AI ukuze kuqikelelwe umngcipheko wokuphulwa kwedama. IBhanki Yehlabathi idwelise obu buchwepheshe kwingxelo yayo.Iprojekthi Yokumelana Nemozulu eMekongizixhobo zokusebenza.

Isiphelo

Eli tyala libonisa indlela izinzwa ze-hydrological ezihlakaniphile ezihlanganisiweyo eziphucula ngayo ulawulo lweentlekele zamanzi kwimimandla yemvula yemvula, zibonelela ngesisombululo esingabizi kakhulu nesinokuthenjwa kumazwe asaphuhlayo.

Iseti epheleleyo yeeseva kunye nemodyuli engenazingcingo yesoftware, ixhasa i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
