Kakaretso ea sensor ea ponahalo
Joalo ka lisebelisoa tsa mantlha tsa tlhahlobo ea tikoloho ea sejoale-joale, li-sensor tsa ponahalo li lekanya phetisetso ea sepakapaka ka nako ea nnete ka melao-motheo ea photoelectric le ho fana ka lintlha tsa bohlokoa tsa boemo ba leholimo bakeng sa liindasteri tse fapaneng. Litharollo tse tharo tse kholo tsa tekheniki ke phetiso (mokhoa oa motheo), ho hasana (ho hasana ho ea pele/ho khutlela morao) le litšoantšo tsa pono. Har'a bona, mofuta oa ho hasanya ka pele o lula 'marakeng o tloaelehileng ka ts'ebetso ea ona e theko e phahameng. Lisebelisoa tse tloaelehileng tse kang letoto la Vaisala FD70 li ka bona liphetoho tsa ponahalo ka har'a sebaka sa 10m ho isa ho 50km ka ho nepahala ha ± 10%. E na le sebopeho sa RS485/Modbus mme e khona ho ikamahanya le maemo a thata a -40 ℃ ho ea ho +60 ℃.
Litekanyetso tsa mantlha tsa tekheniki

Maqhubu a sampole ea data: 1Hz ~ 0.1Hz e ka fetolehang
Tšebeliso e tloaelehileng ea matla: <2W (12VDC motlakase)
Linyeoe tsa kopo ea indasteri
1. Mokhoa o bohlale oa lipalangoang
Marang-rang a lemosang ka litsela tse kholo
Marang-rang a ho lekola ponahalo a kentsoeng Shanghai-Nanjing Expressway a sebelisa li-sensor node 2km e 'ngoe le e 'ngoe ka likarolo tse nang le moholi o mongata. Ha ponahalo e le <200m, lebelo la lebelo le hlahang letlapeng la tlhahisoleseding (120→80km/h) le qalisoa ka bo eona, 'me ha ponahalo e le <50m, monyako oa seteishene sa litefiso oa koaloa. Sistimi e fokotsa sekhahla sa likotsi tsa selemo le selemo sa karolo ena ka 37%.
2. Tlhokomelo ea litsela tsa lifofane
Boema-fofane ba Machabeng ba Beijing Daxing bo sebelisa mefuta e meraro ea li-sensor tse ngata haholo ho hlahisa data ea runway visual range (RVR) ka nako ea nnete. Ha e kopantsoe le tsamaiso ea lisebelisoa tsa ILS, mokhoa oa ho theoha o foufetseng oa Sehlopha sa III o qalisoa ha RVR <550m, ho netefatsa hore lebelo la ho fihla ka nako sefofaneng le eketseha ka 25%.
Tšebeliso e ncha ea ho beha leihlo tikoloho
1. Ho latela tšilafalo ea litoropo
Ofisi ea Tšireletso ea Tikoloho ea Shenzhen e thehile seteishene sa ho shebella se kopaneng-PM2.5 ho National Highway 107, e khelositse coefficient ea ho timela ha aerosol ka ponahalo, 'me ea theha mohlala oa monehelo oa mohloli oa tšilafalo hammoho le data ea phallo ea sephethephethe, e atlehileng ho fumana mosi oa koloi ea diesel e le mohloli o ka sehloohong oa tšilafalo (monehelo oa 62%).
2. Temoso ea kotsi ea mollo oa meru
Ponahalo-mosi oa motsoako oa motsoako o sebelisoang sebakeng sa moru oa Khingan Range o ka potlakela ho fumana mollo ka hare ho metsotso ea 30 ka ho shebella ho fokotseha ho sa tloaelehang ha ponahalo (> 30% / h) le ho sebelisana le ho lemoha mohloli oa mocheso oa infrared, 'me lebelo la ho arabela le phahame ka makhetlo a 4 ho feta mekhoa ea setso.
Maemo a khethehileng a indasteri
1. Boema-kepe ba sekepe sa lifofane
Laser vision meter (mohlala: Biral SWS-200) e sebelisoang Boema-kepeng ba Ningbo Zhoushan ka bo eona e kenya tšebetsong sistimi ea "automatic berthing system" (APS) ha ponahalo e le <1000m, 'me e fihlela phoso ea berthing ea <0.5m maemong a leholimo a moholi ka ho kopanya radar ea millimeter-wave le data ea ponahalo.
2. Tlhokomelo ea polokeho ea kotopo
Ka kotopong ea 'mila o moholo oa Qinling Zhongnanshan, sensor e nang le liparamente tse peli bakeng sa ponahalo le CO concentration e kentsoe 200m e ngoe le e ngoe. Ha ponahalo e le <50m le CO> 150ppm, moralo oa mekhahlelo e meraro oa moea o sebetsa ka bohona, o khutsufatsa nako ea karabo ea kotsi ho metsotsoana e 90.
Mokhoa oa ho iphetola ha theknoloji
Multi-sensor fusion: ho kopanya liparamente tse ngata joalo ka ponahalo, PM2.5, le khatello ea khabone e ntšo.
Edge computing: ts'ebetso ea lehae ho fihlela karabelo ea temoso ea boemo ba millisecond
Meaho ea 5G-MEC: e ts'ehetsa marang-rang a tlase-latency a li-node tse kholo
Mokhoa oa ho ithuta ka mochini: ho theha algorithm ea ho tsebahatsa kotsi ea sephethephethe
Morero o tloaelehileng oa ho tsamaisa
Mohaho oa "dual-machine hot standby + solar power supply" o khothaletsoa bakeng sa maemo a litsela tse kholo, ka bolelele ba palo ea 6m le 30 ° ho sekama ho qoba mabone a ka ho toba. Data fusion algorithm e tlameha ho kenyelletsa mojule oa temoho ea pula le moholi (ho ipapisitse le kamano pakeng tsa sekhahla sa phetoho ea ponahalo le mongobo) ho qoba litemoso tsa bohata nakong ea pula ea litloebelele.
Ka nts'etsopele ea ho khanna ka boithaopo le litoropo tse bohlale, li-sensor tsa ponahalo li ntse li fetoha ho tloha ho lisebelisoa tse le 'ngoe ho ea ho likarolo tsa mantlha tsa pono ea litsamaiso tse bohlale tsa ho etsa liqeto tsa sephethephethe. Theknoloji ea morao-rao e kang Photon Counting LiDAR (PCLidar) e eketsa moeli oa ho lemoha ho ba ka tlase ho 5m, e fana ka tšehetso e nepahetseng haholoanyane ea data bakeng sa tsamaiso ea sephethephethe maemong a leholimo a feteletseng.
