Gushyira mu bikorwa no gusesengura ingaruka za Doppler Radar Sensors muri Indoneziya

Gushyira mu bikorwa Porogaramu mu gutabara ibiza

Nka gihugu kinini ku birwa binini ku isi giherereye ku mpeta y’umuriro wa pasifika, Indoneziya ihora ibangamiwe n’imitingito, tsunami, n’izindi mpanuka kamere. Ubuhanga gakondo bwo gushakisha-gutabara akenshi bugaragaza ko butagize ingaruka mubihe bigoye nko kubaka inyubako zuzuye, aho ikoranabuhanga rya Doppler rishingiye ku buhanga bwa radar sensing itanga ibisubizo bishya. Mu 2022, itsinda ry’ubushakashatsi bwakozwe na Tayiwani na Indoneziya ryashyizeho uburyo bwa radar bushobora kumenya guhumeka kw'abacitse ku icumu binyuze mu rukuta rwa beto, ibyo bikaba byerekana ko umuntu yasimbutse mu bushobozi bwo kumenya ubuzima nyuma y’ibiza.

Ikoranabuhanga ryibanze mu ikoranabuhanga rishingiye ku guhuza radar ya Frequency-Modulated Continuous Wave (FMCW) hamwe na algorithm yo gutunganya ibimenyetso bigezweho. Sisitemu ikoresha uburyo bubiri bwo gupima neza kugirango itsinde ibimenyetso bituruka kumyanda: igereranya rya mbere kandi ryishyura kugoreka kwatewe nimbogamizi nini, mugihe icya kabiri cyibanda ku kumenya kugenda mu gatuza koroheje (ubusanzwe cm 0,5-1,5 cm) kuva guhumeka kugera aho abarokotse. Ibizamini bya laboratoire byerekana ubushobozi bwa sisitemu yo kwinjira mu rukuta rwa cm 40 z'ubugari no kumenya guhumeka kugera kuri metero 3.28 inyuma, hamwe na verisiyo ihagaze kuri cm 3.375 - irenze kure ibikoresho bisanzwe byerekana ubuzima.

Imikorere ikora yemejwe hakoreshejwe uburyo bwo gutabara. Hamwe nabakorerabushake bane bashyizwe inyuma yurukuta rwa beto yubunini butandukanye, sisitemu yatahuye neza ibimenyetso byose byikizamini cyo guhumeka, bikomeza imikorere yizewe nubwo haba hari urukuta rwa cm 40 rutoroshye. Ubu buryo bwo kudahuza bukuraho ibikenewe kugirango abatabazi binjire mu turere tw’akaga, bigabanya cyane ingaruka z’imvune. Bitandukanye nuburyo gakondo bwa acoustic, infragre cyangwa optique, radar ya Doppler ikora idashingiye kumwijima, umwotsi cyangwa urusaku, ituma ibikorwa bya 24/7 bikora mugihe gikomeye cyo gutabara "zahabu-amasaha 72".

Imbonerahamwe: Kugereranya imikorere yubuhanga bwinjira mubuzima

Sisitemu yo guhanga udushya irenze ibisobanuro bya tekiniki kubikorwa byayo bifatika. Igikoresho cyose kigizwe nibice bitatu gusa: moderi ya radar ya FMCW, imashini ikora comptabilite, hamwe na batiri ya 12V ya lithium - byose biri munsi ya 10kg kugirango umuntu akoreshwe. Igishushanyo cyoroheje gikwiranye na geografiya ya Indoneziya kandi yangiza ibikorwa remezo neza. Gahunda yo guhuza ikoranabuhanga hamwe na drone hamwe na platifike ya robo bizarushaho kwaguka kugera ahantu hatagerwaho.

Dufatiye ku mibereho y'abaturage, radar yinjira mu buzima-ishobora kumenya imbaraga zo guhangana n'ibiza muri Indoneziya. Mu gihe cy'umutingito wa tsunami wa Palu 2018, uburyo busanzwe bwagaragaye ko budakora neza mu matongo ya beto, bigatuma abantu bahitanwa n’impanuka. Ikwirakwizwa ry’ikoranabuhanga rishobora kuzamura igipimo cy’abacitse ku icumu ku kigero cya 30-50% mu biza nk'ibi, bishobora kurokora ubuzima bw'abantu amagana cyangwa ibihumbi. Nkuko byashimangiwe na Porofeseri Aloyius Adya Pramudita wo muri kaminuza ya Telkom yo muri Indoneziya, intego nyamukuru y’ikoranabuhanga ihuza neza n’ingamba zo kugabanya ibiza by’ikigo cy’igihugu gishinzwe kurwanya ibiza (BNPB): “kugabanya ubuzima bw’abantu no kwihutisha gukira.”

Ibikorwa byo gucuruza birakomeje cyane, abashakashatsi bafatanya nabafatanyabikorwa mu nganda guhindura laboratoire ya laboratoire ibikoresho byo gutabara bikomeye. Urebye ibikorwa bya Indoneziya bikunze kwibasirwa n’ibiza (impuzandengo ya 5.000+ buri mwaka), ikoranabuhanga rishobora kuba ibikoresho bisanzwe bya BNPB n’ibigo by’ibiza byo mu karere. Itsinda ry’ubushakashatsi rigereranya koherezwa mu murima mu myaka ibiri, biteganijwe ko ibiciro by’ibiciro bizagabanuka kuva kuri $ 15,000 by’amadorari agera kuri 5,000 $ ku gipimo - bityo bikagera ku nzego z’ibanze hirya no hino mu ntara 34 za Indoneziya.

Porogaramu yo gutwara abantu neza

Umubyigano udasanzwe wa Jakarta (uri ku mwanya wa 7 mubi ku isi) watumye habaho udushya twa radar ya Doppler muri sisitemu yo gutwara abantu. Umujyi wa “Smart City 4.0 ″” urimo sensor ya radar 800+ ku masangano akomeye, kugeraho:

• Kugabanuka 30% mumasaha yumubyigano ukoresheje kugenzura ibimenyetso bifatika
• 12% kuzamura umuvuduko wikinyabiziga (kuva 18 kugeza 20.2 km / h)
• Kugabanuka 45-isegonda mugihe cyo gutegereza igihe cyo gutegereza

Sisitemu ikoresha 24GHz ya Doppler radar ikora neza mumvura yo mu turere dushyuha (99% byerekana neza na 85% kuri kamera mugihe cyimvura nyinshi) kugirango ikurikirane umuvuduko wibinyabiziga, ubucucike, nuburebure bwumurongo mugihe nyacyo. Guhuza amakuru hamwe na Centre yo gucunga ibinyabiziga bya Jakarta ituma ibimenyetso byerekana ibihe bigenda bihinduka buri minota 2-5 ukurikije urujya n'uruza rwinshi aho kuba gahunda yagenwe.

Inyigo: Gatot Subroto Umuhanda wo Gutezimbere

• Ibyuma 28 bya radar byashyizwe kuri 4.3km
• Ibimenyetso byo guhuza n'imihindagurikire y'ikirere byagabanije igihe cy'urugendo kuva ku minota 25 kugeza kuri 18
• Umwuka wa CO₂ wagabanutseho toni 1,2 buri munsi
• 35% bike byihohotera ryumuhanda byagaragaye binyuze mubikorwa byikora

Igenzura rya Hydrologiya mu gukumira umwuzure

Indoneziya sisitemu yo kuburira hakiri kare yahujije ikoranabuhanga rya radar ya Doppler mu kibaya 18 kinini. Umushinga wibibaya byumugezi wa Ciliwung urerekana iyi porogaramu:

• Sitasiyo ya 12 ya radar ipima umuvuduko wubuso buri minota 5
• Uhujwe na ultrasonic water urwego rwamazi yo kubara
• Amakuru yatanzwe binyuze kuri GSM / LoRaWAN muburyo bwo guhanura imyuzure
• Umuburo wo kuyobora wongerewe kuva kumasaha 2 kugeza kuri 6 muri Greater Jakarta

Ibipimo bya radar bidahuye byerekana ko bifite agaciro cyane mugihe cyumwuzure wuzuye imyanda aho metero gakondo zananirana. Gushyira ku biraro birinda ingaruka z’amazi mugihe utanga igenzura rihoraho ridatewe nubutaka.

Kubungabunga amashyamba no kurengera inyamaswa

Muri Ecusosystem ya Leuser ya Sumatra (ubuturo bwa nyuma bwa orangutani ya Sumatran), radar ya Doppler ifasha muri:

1. Igenzura rirwanya guhiga

• 60GHz radar itahura imigendekere yabantu ikoresheje amababi yuzuye
• Itandukanya ba rushimusi ninyamaswa zifite 92% byukuri
• Gupfuka radiyo 5km kuri buri gice (vs 500m kuri kamera ya infragre)

2. Gukurikirana Canopy

• Millimetero-umuraba radar ikurikirana ibiti byerekana
• Kumenya ibikorwa byo gutema ibiti bitemewe mugihe nyacyo
• Yagabanije gutema ibiti bitemewe na 43% mubice byicyitegererezo

Sisitemu ikoresha ingufu nke (15W / sensor) ituma imirasire y'izuba ikorera ahantu kure, ikohereza imenyesha ikoresheje satelite mugihe ibonye ibikorwa biteye amakenga.

Ibibazo hamwe nicyerekezo kizaza

Nubwo ibisubizo bitanga icyizere, kurera abana benshi bahura nimbogamizi zishyirwa mubikorwa:

1. Imipaka ya tekinike

• Ubushyuhe bwinshi (> 80% RH) burashobora guhuza ibimenyetso byinshyi
• Ibidukikije byuzuye mumijyi bitera inzira nyinshi
• Ubuhanga buke bwa tekinike yo kubungabunga

2. Ibintu byubukungu

• Igikoresho cya sensor igezweho ($ 3000- $ 8,000 / unit) irwanya ingengo yimari yaho
• Ibara rya ROI ntirisobanutse kuri komine zifitemo amafaranga
• Kwishingikiriza kubatanga hanze kubice byingenzi

3. Inzitizi z'inzego

• Kugabana amakuru ahuza ibigo bikomeje kuba ikibazo
• Kubura protocole isanzwe yo guhuza amakuru ya radar
• Gutinda kugenzura kugabanwa kugabanwa

Ibisubizo bivuka birimo:

• Gutezimbere sisitemu irwanya ubushuhe 77GHz
• Gushiraho ibikoresho byiteranirizo byaho kugirango ugabanye ibiciro
• Gushiraho gahunda za leta-za kaminuza-inganda zohereza ubumenyi
• Gushyira mubikorwa ingamba zo gutangiza ibyiciro bitangirana nibice byinshi

Porogaramu izaza kuri horizon irimo:

• Imiyoboro ya radar ishingiye kuri drone kugirango isuzume ibiza
• Sisitemu yo gutahura sisitemu
• Gukurikirana akarere keza kuroba kugirango wirinde kuroba cyane
• Isuri yo ku nkombe ikurikirana hamwe na milimetero-yuzuye

Hamwe n’ishoramari rikwiye hamwe n’inkunga ya politiki, ikoranabuhanga rya radar ya Doppler rishobora kuba urufatiro rw’imihindagurikire y’ikoranabuhanga rya Indoneziya, rikazamura imbaraga mu birwa byayo 17,000 mu gihe hashyirwaho uburyo bushya bwo kubona akazi mu buhanga buhanitse. Ubunararibonye bwa Indoneziya bwerekana uburyo ikoranabuhanga rigezweho rishobora gukoreshwa kugira ngo rikemure ibibazo by’ibihugu bikiri mu nzira y'amajyambere iyo bishyizwe mu bikorwa hamwe n’ingamba zikwiye.
