Izicelo Zokuthuthuka Ekutakuleni Izinhlekelele
Njengoba iyisizwe esikhulu kunazo zonke emhlabeni esihlala eduze kwePacific Ring of Fire, i-Indonesia ibhekene nezinsongo eziqhubekayo zokuzamazama komhlaba, ama-tsunami, nezinye izinhlekelele zemvelo. Amasu okusesha nokuhlenga endabuko avame ukungasebenzi ezimweni eziyinkimbinkimbi njengokuwa kwesakhiwo ngokuphelele, lapho ubuchwepheshe bokubona i-radar obusekelwe ku-Doppler buhlinzeka ngezixazululo ezintsha. Ngo-2022, ithimba locwaningo elihlangene laseTaiwan-Indonesia lakha uhlelo lwe-radar olukwazi ukubona ukuphefumula kwabasindile ngezindonga zekhonkrithi, okumelela ukukhuphuka okukhulu kwamakhono okuthola impilo ngemva kwenhlekelele.
Ubuchwepheshe obusha obuyinhloko busekuhlanganisweni kwayo kwe-radar ye-Frequency-Modulated Continuous Wave (FMCW) nama-algorithms okucubungula amasignali athuthukile. Uhlelo lusebenzisa ukulandelana okubili kokulinganisa okunembile ukunqoba ukuphazamiseka kwesignali okuvela emfucumfucwini: okokuqala kulinganisa futhi kuhlawulele ukuphambuka okubangelwa izithiyo ezinkulu, kanti okwesibili kugxila ekutholeni ukunyakaza kwesifuba okucashile (ngokuvamile okungu-0.5-1.5 cm amplitude) kusukela ekuphefumuleni kuya ekutholeni izindawo ezisindile. Ukuhlolwa kwelebhu kubonisa ikhono lohlelo lokungena ezindongeni zekhonkrithi ezingama-40 cm ubukhulu futhi libone ukuphefumula okufika kumamitha angu-3.28 ngemuva, ngokunemba kokubeka ngaphakathi kuka-±3.375 cm - kudlula kakhulu imishini yokuhlola impilo evamile.
Ukusebenza kahle kokusebenza kwaqinisekiswa ngezimo zokutakula ezilingisiwe. Njengoba izisebenzi zokuzithandela ezine zibekwe ngemuva kwezindonga zekhonkrithi ezinobukhulu obuhlukahlukene, uhlelo lukwazile ukubona ngempumelelo izimpawu zokuphefumula zabo bonke abantu abahlolwayo, lugcina ukusebenza okuthembekile ngisho nangaphansi kwesimo sodonga esiyinselele kakhulu esingamasentimitha angu-40. Le ndlela yokungathintani iqeda isidingo sokuba abatakuli bangene ezindaweni eziyingozi, okunciphisa kakhulu izingozi zokulimala kwesibili. Ngokungafani nezindlela zendabuko ze-acoustic, infrared noma optical, i-Doppler radar isebenza ngokuzimela ebumnyameni, entuthwini noma emsindweni, okwenza kube lula ukusebenza amahora angu-24 ngosuku, izinsuku eziyi-7 ngesonto ngesikhathi sefasitela lokutakula elibalulekile "lamahora angu-72 egolide".

Inani elisha lesistimu lidlula ngale kwemininingwane yobuchwepheshe liye ekusetshenzisweni kwalo okusebenzayo. Lonke idivayisi liqukethe izingxenye ezintathu kuphela: i-module ye-radar ye-FMCW, iyunithi yokubala encane, kanye nebhethri le-lithium elingu-12V - konke okungaphansi kuka-10kg ukuze kube lula ukuphatheka komuntu oyedwa. Lo mklamo olula ufanelana kahle nendawo yase-Indonesia kanye nezimo zengqalasizinda ezonakele. Izinhlelo zokuhlanganisa ubuchwepheshe nama-drones namapulatifomu e-robotic zizokwandisa ukufinyelela kwayo ezindaweni ezingafinyeleleki.
Ngokombono womphakathi, i-radar yokuthola impilo engene ngaphakathi ingathuthukisa kakhulu amandla okusabela ezinhlekeleleni zase-Indonesia. Ngesikhathi sokuzamazama komhlaba kwe-tsunami ePalu ka-2018, izindlela ezivamile zabonakala zingasebenzi kahle emfucumfucwini yekhonkrithi, okwaholela ekulimaleni okungavinjelwa. Ukusetshenziswa kabanzi kwalobu buchwepheshe kungathuthukisa amazinga okuthola abasindile ngo-30-50% ezinhlekeleleni ezifanayo, okungasindisa amakhulu noma izinkulungwane zezimpilo. Njengoba kugcizelelwe nguSolwazi u-Aloyius Adya Pramudita wase-Telkom University yase-Indonesia, umgomo wokugcina wobuchwepheshe uhambisana kahle nesu lokunciphisa inhlekelele le-National Disaster Management Agency (BNPB): "ukunciphisa ukulahlekelwa yimpilo nokusheshisa ukululama."
Imizamo yokuhweba iyaqhubeka, abacwaningi bebambisana nabalingani bemboni ukuguqula i-prototype yelabhorethri ibe imishini yokutakula eqinile. Uma sibheka umsebenzi wokuzamazama komhlaba ovame ukwenziwa e-Indonesia (okulinganiselwa kokuzamazama okungu-5,000+ ngonyaka), ubuchwepheshe bungaba imishini ejwayelekile ye-BNPB kanye nezinhlangano zezinhlekelele zesifunda. Ithimba locwaningo lilinganisela ukuthunyelwa kwensimu kungakapheli iminyaka emibili, kanti izindleko zamayunithi kulindeleke ukuthi zehle kusukela ku-prototype yamanje engu-$15,000 ziye ngaphansi kuka-$5,000 esikalini - okwenza kube lula kohulumeni basekhaya kuzo zonke izifundazwe ezingu-34 zase-Indonesia.
Izicelo Zokuphathwa Kwezokuthutha Ezihlakaniphile
Ukuminyana kwezimoto okungapheli eJakarta (okubekwe endaweni yesi-7 okubi kakhulu emhlabeni jikelele) kuholele ekusetshenzisweni okusha kwe-radar ye-Doppler ezinhlelweni zokuhamba ezihlakaniphile. Uhlelo lwedolobha lwe-“Smart City 4.0” luhlanganisa izinzwa ze-radar ezingaphezu kuka-800 ezindaweni ezibalulekile, okufeza:
