Ukubuka konke kwenzwa yokubonakala
Njengemishini eyinhloko yokuqapha kwemvelo yesimanje, izinzwa zokubona zilinganisa ukudluliselwa komoya ngesikhathi sangempela ngezimiso ze-photoelectric futhi zihlinzeka ngemininingwane ebalulekile yesimo sezulu yezimboni ezahlukene. Izixazululo ezintathu zobuchwepheshe eziyinhloko ukudluliselwa (indlela eyisisekelo), ukusabalalisa (ukusabalalisa phambili/emuva) kanye nokuthwebula izithombe. Phakathi kwazo, uhlobo lokusabalalisa phambili luthatha imakethe evamile ngokusebenza kwayo okubiza kakhulu. Imishini ejwayelekile njengochungechunge lwe-Vaisala FD70 ingathola izinguquko zokubonakala ngaphakathi kwebanga eliphakathi kwamamitha ayi-10 kuya kwangama-50km ngokunemba okungu-±10%. Ifakwe isikhombimsebenzisi se-RS485/Modbus futhi ingazivumelanisa nezimo ezinzima kusukela ku--40℃ kuya ku-+60℃.
Amapharamitha obuchwepheshe ayinhloko
Uhlelo lokuzihlanza olusebenzisa amafasitela olubonakalayo (njengokususa uthuli lokudlidliza nge-ultrasonic)
Ubuchwepheshe bokuhlaziya ama-spectral aneziteshi eziningi (850nm/550nm ubude obuphindwe kabili)
I-algorithm yesinxephezelo esinamandla (ukulungiswa kokuphazamiseka kokushisa nomswakama)
Imvamisa yokusampula idatha: 1Hz ~ 0.1Hz elungisekayo
Ukusetshenziswa kwamandla okuvamile: <2W (ukunikezwa kwamandla okungu-12VDC)
Amacala okusebenza embonini
1. Uhlelo lokuhamba oluhlakaniphile
Inethiwekhi yezexwayiso zangaphambi komgwaqo omkhulu
Inethiwekhi yokuqapha ukubonakala esetshenziswa ku-Shanghai-Nanjing Expressway isebenzisa ama-sensor node njalo ngamakhilomitha ama-2 ngezigaba lapho kuvela khona inkungu kakhulu. Uma ukubonakala kungaphansi kwama-200m, isivinini esikhawulelwe ebhodini lolwazi (120→80km/h) sivulwa ngokuzenzakalelayo, futhi uma ukubonakala kungaphansi kwama-50m, umnyango wesiteshi semali uyavalwa. Uhlelo lunciphisa isilinganiso sengozi yonyaka salesi sigaba ngo-37%.
2. Ukuqapha indlela yendiza yesikhumulo sezindiza
Isikhumulo Sezindiza Samazwe Ngamazwe saseBeijing Daxing sisebenzisa i-triple redundant sensor array ukukhiqiza idatha ye-runway visual range (RVR) ngesikhathi sangempela. Uma ihlanganiswe nohlelo lokufika kwezinsimbi ze-ILS, inqubo yokufika ngokungaboni yeSigaba III iqalwa lapho i-RVR ingaphansi kwama-550m, okuqinisekisa ukuthi izinga lokugcina isikhathi sokundiza liyakhuphuka ngo-25%.
Ukusetshenziswa okusha kokuqapha kwemvelo
1. Ukulandelela ukungcola kwasemadolobheni
I-Shenzhen Environmental Protection Bureau yasungula isiteshi sokubuka esihlangene se-visibility-PM2.5 ku-National Highway 107, yaguqula i-aerosol extinction coefficient ngokubonakala, futhi yasungula imodeli yomnikelo womthombo wokungcola kanye nedatha yokuhamba kwethrafikhi, yathola ngempumelelo ukukhishwa kwemoto kadizili njengomthombo oyinhloko wokungcola (umnikelo ongu-62%).
2. Isexwayiso ngengozi yomlilo wehlathi
Inethiwekhi yezinzwa ezibonakalayo nentuthu ehlanganisiwe esetshenziswa endaweni yehlathi iGreater Khingan Range ingathola umlilo ngokushesha zingakapheli imizuzu engama-30 ngokuqapha ukwehla okungavamile kokubonakala (>30%/h) kanye nokubambisana nokutholwa komthombo wokushisa we-infrared, futhi isivinini sokuphendula siphakeme ngokuphindwe kane kunezindlela zendabuko.
Izimo ezikhethekile zezimboni
1. Uhambo lomkhumbi wechweba
Imitha yokubona nge-laser (imodeli: Biral SWS-200) esetshenziswa eNingbo Zhoushan Port ivula ngokuzenzakalelayo uhlelo lokufika ngokuzenzakalelayo komkhumbi (i-APS) lapho ukubonakala kungaphansi kuka-1000m, futhi ifinyelela iphutha lokufika elingaphansi kuka-0.5m esimweni sezulu esinomswakama ngokuhlanganisa i-radar yamagagasi angamamilimitha nedatha yokubonakala.
2. Ukuqapha ukuphepha komhubhe
Emhubheni omkhulu we-Qinling Zhongnanshan, kufakwa inzwa enamapharamitha amabili yokubonakala kanye nokuhlushwa kwe-CO njalo ngamamitha angu-200. Uma ukubonakala kungaphansi kwama-50m kanye ne-CO>150ppm, uhlelo lokungenisa umoya olunezinga ezintathu luvuselelwa ngokuzenzakalelayo, okunciphisa isikhathi sokuphendula engozini sibe yimizuzwana engama-90.
Umkhuba wokuvela kobuchwepheshe
Ukuhlanganiswa kwezinzwa eziningi: ukuhlanganisa amapharamitha amaningi njengokubonakala, i-PM2.5, kanye nokuhlushwa kwekhabhoni emnyama
I-Edge computing: ukucubungula kwendawo ukuze kufezwe impendulo yesixwayiso sezinga le-millisecond
Ukwakhiwa kwe-5G-MEC: kusekela inethiwekhi ye-low-latency yama-node amakhulu
Imodeli yokufunda komshini: ukusungula i-algorithm yokubikezela amathuba okubonakala kwengozi yethrafikhi
Uhlelo olujwayelekile lokufaka
Umklamo "wokumisa okushisa okwenziwa ngomshini okabili + ukunikezwa kwamandla elanga" uyanconywa ezimweni zomgwaqo omkhulu, ngokuphakama kwesigxobo esingu-6m kanye nokuthambekela okungu-30° ukuze kugwenywe izibani eziqondile. I-algorithm yokuhlanganisa idatha kumele ifake imojuli yokubona imvula kanye nenkungu (ngokusekelwe ekuxhumaneni phakathi kwesilinganiso sokushintsha kokubonakala kanye nomswakama) ukuze kugwenywe ama-alamu angamanga esimweni sezulu semvula enkulu.
Ngokuthuthukiswa kwezimoto zokushayela ezizimele kanye namadolobha ahlakaniphile, izinzwa zokubona ziyashintsha kusukela kumadivayisi okuthola okukodwa kuya kumayunithi okuqonda ayinhloko ezinhlelo zokwenza izinqumo zethrafikhi ezihlakaniphile. Ubuchwepheshe bamuva njenge-Photon Counting LiDAR (PCLidar) bandisa umkhawulo wokuthola ube ngaphansi kwamamitha angu-5, okunikeza ukwesekwa kwedatha okunembile kakhulu kokuphathwa kwethrafikhi ezimweni zezulu ezimbi kakhulu.
