Kuonekwa kwe sensor pamusoro
Semidziyo yakakosha yekutarisisa kwezvakatipoteredza, ma sensors ekuonekwa anoyera kutapurirana kwemuchadenga munguva chaiyo kuburikidza nemisimboti yephotoelectric uye inopa yakakosha meteorological data kumaindasitiri akasiyana. Iwo matatu makuru ehunyanzvi mhinduro ndeyekutapurirana (yekutanga nzira), kuparadzira (kumberi / kumashure kuparadzira) uye kufungidzira kwekuona. Pakati pazvo, rudzi rwekuparadzira kumberi runogara mumusika mukuru nemutengo wayo wepamusoro. Midziyo yemhando yakadai seVaisala FD70 yakatevedzana inogona kuona shanduko yekuonekwa mukati meiyo 10m kusvika 50km nekurongeka kwe ± 10%. Iyo ine RS485 / Modbus interface uye inokwanisa kuchinjika kune dzakaoma nharaunda dze -40 ℃ kusvika +60 ℃.
Core technical parameters
Optical hwindo rekuzvichenesa system (senge ultrasonic vibration kubvisa guruva)
Multi-channel spectral yekuongorora tekinoroji (850nm/550nm dual wavelength)
Dynamic compensation algorithm (tembiricha uye humidity cross-interference correction)
Data sampling frequency: 1Hz ~ 0.1Hz inogadziriswa
Yakajairika simba rekushandisa: <2W (12VDC magetsi emagetsi)
Indasitiri application kesi
1. Hungwaru hwekufambisa hurongwa
Highway early yambiro network
Iyo yekuonekwa yekutarisa network yakaisirwa paShanghai-Nanjing Expressway inoisa sensor node 2km yega yega muzvikamu zvine huwandu hwemhute. Kana kuoneka kuri <200m, nhanho yekumhanyisa pabhodhi reruzivo (120→ 80km/h) inokonzereswa, uye kana kuoneka kuri <50m, yekupinda chiteshi chinovharwa. Hurongwa hunoderedza avhareji yengozi dzepagore dzechikamu ichi ne37%.
2. Airport runway monitoring
Beijing Daxing International Airport inoshandisa katatu redundant sensor array kugadzira runway visual range (RVR) data munguva chaiyo. Yakasanganiswa neILS instrument yekumhara system, iyo Category III yebofu yekumhara inotangwa kana RVR <550m, kuve nechokwadi chekuti chiyero chekumhanya kwendege chinowedzerwa ne25%.
Innovative application yekuongorora kwezvakatipoteredza
1. Kutsvaga kusvibiswa kwemaguta
Shenzhen Environmental Protection Bureau yakamisa chiteshi chekutarisa-PM2.5 yakabatana paNational Highway 107, yakadzora coefficient yekutsakatika kweaerosol kuburikidza nekuonekwa, uye yakamisa kusvibisa sosi yemupiro musanganiswa neiyo traffic flow data, yakabudirira kutsvaga edhiziri yemotokari seyo huru yekusvibisa (mupiro 62%).
2. Yambiro yengozi yemoto wesango
Iyo yekuonekwa-utsi inoumbwa sensor network inoiswa munzvimbo yemasango yeGreater Khingan Range inogona kukurumidza kutsvaga moto mukati memaminitsi makumi matatu nekutarisa kuderera kusingawanzo kuoneka (> 30% / h) uye kushandira pamwe nekuona infrared heat source, uye kukurumidza kwekupindura kuri 4 nguva yakakwirira kupfuura iyo yemaitiro echinyakare.
Zviitiko zveindasitiri zvakakosha
1. Port ship piloge
Iyo laser visibility meter (modhi: Biral SWS-200) inoshandiswa muNingbo Zhoushan Port inomisikidza ngarava otomatiki berthing system (APS) kana kuoneka kuri <1000m, uye inowana kukanganisa kwe <0.5m in foggy weather nekusanganisa millimeter-wave radar ine data yekuona.
2. Tunnel kuchengetedza kuchengetedza
MuQinling Zhongnanshan highway tunnel, mbiri-parameter sensor yekuonekwa uye CO concentration inoiswa yega 200m. Kana kuoneka kuri <50m uye CO> 150ppm, iyo matatu-level chirongwa chekufefetera chinongoitwa otomatiki, ichipfupisa nguva yekupindura tsaona kusvika kumasekonzi makumi mapfumbamwe.
Technology evolution maitiro
Multi-sensor fusion: kubatanidza akawanda paramita senge kuoneka, PM2.5, uye dema kabhoni concentration.
Edge komputa: kugadzirisa kwenzvimbo kuti uwane millisecond-level yambiro mhinduro
5G-MEC dhizaini: inotsigira yakaderera-latency network yenzvimbo huru
Machine yekudzidza modhi: kumisikidza kuoneka-traffic tsaona mukana wekufungidzira algorithm
Yakajairika chirongwa chekuendesa
Iyo "dual-machine hot standby + solar power supply" yekuvaka inokurudzirwa kumigwagwa mikuru, ine danda kureba 6m uye 30 ° tilt kudzivirira zvakananga headlights. Iyo data fusion algorithm inofanira kusanganisira mvura uye fog recognition module (zvichienderana nehukama pakati pekuonekwa shanduko mwero uye humidity) kudzivirira maaramu enhema mukunaya kwemvura.
Nekuvandudzwa kwekuzvimiririra kutyaira uye maguta akangwara, ma sensors ekuonekwa ari kubuda kubva kune imwe chete yekuona michina kuenda kune epakati maonero mayuniti ehungwaru traffic yekuita sarudzo masisitimu. Iwo azvino matekinoroji akadai sePhoton Kuverenga LiDAR (PCLidar) anowedzera muganho wekuona kusvika pazasi 5m, ichipa ruzivo rwakanyanya rwerutsigiro rwekutarisira traffic mumamiriro ekunze ekunze.
