Incamake ya sensor igaragara
Nkibikoresho byibanze byo kugenzura ibidukikije bigezweho, ibyuma byifashishwa bipima ihererekanyabubasha ry’ikirere mu gihe nyacyo binyuze mu mahame y’amashanyarazi kandi bigatanga amakuru y’ikirere y’inganda zitandukanye. Ibisubizo bitatu byingenzi bya tekiniki ni ugukwirakwiza (uburyo bwibanze), gutatanya (gusasa imbere / gusubira inyuma) no kwerekana amashusho. Muri byo, ubwoko bwo gusasa imbere bufata isoko nyamukuru hamwe nigiciro cyayo kinini. Ibikoresho bisanzwe nka seriveri ya Vaisala FD70 irashobora kumenya impinduka zigaragara hagati ya 10m na 50km hamwe nukuri kwa 10%. Ifite ibikoresho bya RS485 / Modbus kandi irashobora guhuza nibidukikije bikaze bya -40 ℃ kugeza + 60 ℃.
Ibikoresho bya tekinike
Sisitemu nziza yo kwisukura sisitemu (nka ultrasonic vibration ivanaho ivumbi)
Ubuhanga bwo gusesengura imiyoboro myinshi (850nm / 550nm uburebure bwa kabiri)
Indishyi zidasanzwe algorithm (ubushyuhe nubushuhe bwambukiranya imipaka)
Inshuro zicyitegererezo: 1Hz ~ 0.1Hz irashobora guhinduka
Gukoresha ingufu zisanzwe: <2W (12VDC itanga amashanyarazi)
Inganda zisaba inganda
1. Sisitemu yo gutwara abantu ifite ubwenge
Umuhanda wo kuburira hakiri kare
Umuyoboro ukurikirana woherejwe kuri Shanghai-Nanjing Expressway wohereza ibyuma bya sensor buri kilometero 2 mu bice bifite ibicu byinshi. Iyo ibiboneka ari <200m, umuvuduko ntarengwa wihuta ku kibaho cyamakuru (120 → 80km / h) uhita utera, kandi iyo kugaragara ari <50m, ubwinjiriro bwa sitasiyo burafungwa. Sisitemu igabanya impuzandengo yimpanuka yumwaka yiki gice kuri 37%.
2. Gukurikirana ikibuga cyindege
Ikibuga cy’indege mpuzamahanga cya Pekin Daxing gikoresha ibyuma byikubye gatatu byerekana ibyerekezo byerekana inzira (RVR) mugihe nyacyo. Hamwe na sisitemu yo kugwa ibikoresho bya ILS, icyiciro cya III uburyo bwo kugwa buhumyi gitangira iyo RVR <550m, ikemeza ko igipimo cyigihe cyo kuguruka cyiyongereyeho 25%.
Gukoresha udushya two gukurikirana ibidukikije
1. Gukurikirana umwanda
Ibiro bishinzwe kurengera ibidukikije bya Shenzhen byashyizeho sitasiyo ihuriweho na PM2.5 ihuriweho n’umuhanda w’igihugu 107, ihindura coefficente yo kuzimya aerosol binyuze mu kugaragara, inashyiraho icyitegererezo cy’intandaro y’umwanda ifatanije n’amakuru y’imihanda, ibona neza imyuka y’ibinyabiziga bya mazutu nk’isoko nyamukuru y’umwanda (umusanzu 62%).
2. Kuburira inkongi y'umuriro
Umuyoboro ugaragara-umwotsi wibikoresho bikoreshwa mukarere ka mashyamba manini ya Khingan Range urashobora kubona vuba umuriro muminota 30 ukurikirana igabanuka ridasanzwe ryibonekeje (> 30% / h) no gufatanya no kumenya ubushyuhe bwumuriro, kandi umuvuduko wo gusubiza wikubye inshuro 4 ugereranije nuburyo gakondo.
Ibihe bidasanzwe byinganda
1. Gutwara ubwato bwicyambu
Imetero ya laser igaragara (icyitegererezo: Biral SWS-200) ikoreshwa ku cyambu cya Ningbo Zhoushan ihita ikora sisitemu yo kubyara ibyuma byikora (APS) mugihe ibiboneka ari <1000m, kandi ikagera ku ikosa ryo kubyara rya <0.5m mugihe cyikirere gihuza radar ya milimetero-yumurongo hamwe namakuru agaragara.
2. Gukurikirana umutekano wumuhanda
Mu muhanda munini wa Qinling Zhongnanshan, ibyuma bibiri byerekana ibyerekezo hamwe na CO byashyizwe kuri 200m. Iyo ibiboneka ari <50m na CO> 150ppm, gahunda yo guhumeka ibyiciro bitatu ihita ikora, bigabanya igihe cyo gutabara impanuka kugeza kumasegonda 90.
Inzira y'ubwihindurize
Multi-sensor fusion: guhuza ibipimo byinshi nko kugaragara, PM2.5, hamwe na karubone yumukara
Kubara impande: gutunganya hafi kugirango ugere kuri milisegonda-urwego rwo kuburira igisubizo
5G-MEC imyubakire: gushyigikira imiyoboro mito-itinze ihuza imiyoboro minini
Imashini yiga imashini: gushiraho ibiboneka-impanuka yimodoka ishobora guhanura algorithm
Gahunda yo kohereza
Imyubakire ya "dual-machine hot standby + sun power power" irasabwa kwerekana inzira nyabagendwa, ifite uburebure bwa pole ya 6m na 30 ° ihanamye kugirango wirinde amatara ataziguye. Data fusion algorithm igomba kuba irimo imvura yo kumenya ibicu (hashingiwe ku isano riri hagati yikigereranyo cy’imihindagurikire y’ubushuhe) kugira ngo wirinde gutabaza ibinyoma mu gihe cy’imvura nyinshi.
Hamwe niterambere ryimodoka yigenga hamwe nibisagara byubwenge, ibyuma biboneka bigenda bihindagurika biva mubikoresho bimwe bimenyekanisha bikagera kumyumvire yibanze ya sisitemu yo gufata ibyemezo byubwenge. Ikoranabuhanga rigezweho nka Photon Counting LiDAR (PCLidar) ryongerera imipaka kugera munsi ya 5m, ritanga amakuru yukuri yukuri yo gucunga ibinyabiziga mubihe bikabije.
