Isishwankathelo senzwa yokubonakala
Njengezixhobo eziphambili zokujonga imeko-bume yanamhlanje, izinzwa zokubona zilinganisa ukuhanjiswa komoya ngexesha langempela ngokusebenzisa imigaqo ye-photoelectric kwaye zibonelela ngedatha ebalulekileyo yemozulu kumashishini ahlukeneyo. Izisombululo ezintathu zobugcisa eziphambili kukudluliselwa (indlela yokuqala), ukusasaza (ukusasaza phambili/ngasemva) kunye nemifanekiso ebonakalayo. Phakathi kwazo, uhlobo lokusasaza phambili luthatha indawo kwimarike eqhelekileyo ngokusebenza kwayo okubiza kakhulu. Izixhobo eziqhelekileyo ezifana nothotho lweVaisala FD70 zinokubona utshintsho lokubonakala ngaphakathi komgama we-10m ukuya kwi-50km ngokuchaneka kwe-±10%. Ixhotyiswe nge-RS485/Modbus interface kwaye inokuqhelana neendawo ezinzima ukusuka kwi--40℃ ukuya kwi-+60℃.
Iiparameter zobugcisa eziphambili
Inkqubo yokuzicoca iifestile ezibonakalayo (njengokususa uthuli lokungcangcazela nge-ultrasonic)
Itekhnoloji yohlalutyo lwe-spectral yeziteshi ezininzi (850nm/550nm ubude obuphindwe kabini)
I-algorithm yembuyekezo enamandla (ukulungiswa kokuphazamiseka kobushushu kunye nokufuma)
Isantya sokuvavanya idatha: 1Hz ~ 0.1Hz elungisekayo
Ukusetyenziswa kwamandla okuqhelekileyo: <2W (umbane we-12VDC)
Amatyala ezicelo zoshishino
1. Inkqubo yothutho ekrelekrele
Inethiwekhi yesilumkiso sakwangoko yendlela enkulu
Inethiwekhi yokujonga ukubonakala esetyenziswa kwiShanghai-Nanjing Expressway ithumela ii-sensor nodes rhoqo emva kwe-2km kwiindawo apho kukho inkungu eninzi khona. Xa ukubonakala kungaphantsi kwe-200m, isantya esikhawulezileyo kwibhodi yolwazi (120→80km/h) sivulwa ngokuzenzekelayo, kwaye xa ukubonakala kungaphantsi kwe-50m, isango lesikhululo serhafu liyavalwa. Le nkqubo inciphisa izinga eliqhelekileyo leengozi zonyaka zale ndawo ngama-37%.
2. Ukujonga indlela yeenqwelo moya kwisikhululo seenqwelo-moya
Isikhululo seenqwelo-moya saseBeijing Daxing International sisebenzisa uluhlu lwe-sensor oluphindwe kathathu ukuvelisa idatha ye-runway visual range (RVR) ngexesha langempela. Idibene nenkqubo yokufika kwezixhobo ze-ILS, inkqubo yokufika ngokungaboniyo yeCandelo III iqaliswa xa i-RVR ingaphantsi kwama-550m, ukuqinisekisa ukuba izinga lokufika ngexesha lokubhabha linyuswa ngama-25%.
Ukusetyenziswa okutsha kokubeka esweni okusingqongileyo
1. Ukulandelwa kongcoliseko lwasezidolophini
I-Shenzhen Environmental Protection Bureau imisele isikhululo sokujonga esidibeneyo se-visibility-PM2.5 kwiNational Highway 107, yaguqula i-aerosol extinction coefficient ngokubonakala, yaza yaseka imodeli yomnikelo womthombo wongcoliseko kunye nedatha yokuhamba kwezithuthi, yafumana ngempumelelo umsi wezithuthi zedizili njengomthombo ophambili wongcoliseko (igalelo lama-62%).
2. Isilumkiso somngcipheko womlilo wamahlathi
Inethiwekhi ye-sensor ebonakalayo-yomsi edibeneyo efakwe kwindawo yehlathi iGreater Khingan Range inokufumana umlilo ngokukhawuleza kwimizuzu engama-30 ngokujonga ukwehla okungaqhelekanga kokubonakala (>30%/h) kunye nokusebenzisana nokufunyanwa komthombo wobushushu obuphantsi kwe-infrared, kwaye isantya sempendulo siphezulu ngokuphindwe kane kuneendlela zemveli.
Iimeko ezikhethekileyo zoshishino
1. Uhambo lokuqhuba inqanawa yezibuko
Imitha yokubona nge-laser (imodeli: Biral SWS-200) esetyenziswa kwiNingbo Zhoushan Port ivula ngokuzenzekelayo inkqubo yokubeka inqanawa ngokuzenzekelayo (i-APS) xa ukubonakala kungaphantsi kwe-1000m, kwaye ifezekisa impazamo yokubeka inqanawa engaphantsi kwe-0.5m kwimozulu enenkungu ngokudibanisa i-radar yamaza e-millimeter kunye nedatha yokubonakala.
2. Ukubeka iliso kukhuseleko lomjelo
Kwi-tunnel yendlela iQinling Zhongnanshan, kufakwa i-sensor ene-double-parameter sensor yokujonga kunye noxinzelelo lwe-CO rhoqo kwi-200m. Xa ukubonakala kungaphantsi kwe-50m kunye ne-CO>150ppm, isicwangciso somoya samanqanaba amathathu sisebenza ngokuzenzekelayo, sinciphisa ixesha lokuphendula kwingozi ukuya kwimizuzwana engama-90.
Inkqubela phambili kwezobuchwepheshe
Ukuhlanganiswa kwee-sensor ezininzi: ukudibanisa iiparameter ezininzi ezifana nokubonakala, i-PM2.5, kunye noxinzelelo lwekhabhoni emnyama
I-Edge computing: ukucutshungulwa kwendawo ukuze kufunyanwe impendulo yesilumkiso senqanaba le-millisecond
Uyilo lwe-5G-MEC: luxhasa uthungelwano oluphantsi lwe-latency lwee-nodes ezinkulu
Imodeli yokufunda koomatshini: ukuseka i-algorithm yokuqikelela amathuba okubonakala kwengozi yetrafikhi
Isicwangciso esiqhelekileyo sokusasazwa
Uyilo "lwe-hot-standby yoomatshini ababini kunye nombane welanga" luyacetyiswa kwiimeko zendlela enkulu, enokuphakama kwepali eyi-6m kunye nokuthambeka okungama-30° ukuze kuthintelwe izibane zentloko ezithe ngqo. I-algorithm yokudibanisa idatha kufuneka ibandakanye imodyuli yokuqaphela imvula kunye nenkungu (esekelwe kulwalamano phakathi kwesantya sokutshintsha kokubonakala kunye nokufuma) ukuze kuthintelwe ii-alamu zobuxoki xa imvula inkulu.
Ngophuhliso lwezixeko ezizisebenzela ngokwazo kunye nezikrelekrele, izinzwa zokubona ziyatshintsha ukusuka kwizixhobo zokubona izinto ezikude ukuya kwiiyunithi zokuqonda eziphambili zeenkqubo zokwenza izigqibo zendlela ezikrelekrele. Ubuchwepheshe bamva nje obufana ne-Photon Counting LiDAR (PCLidar) bandisa umda wokubona ukuya ngaphantsi kwe-5m, nto leyo ebonelela ngenkxaso yedatha echanekileyo ngakumbi kulawulo lwendlela kwiimeko zemozulu ezimbi.
