Isiginali ye-lifti yaphansi engu-20, isethi “yekheshiisiphindaphinda sesignali” ukuxazulula inkinga yokuhlanganisa ngokugcwele.Iphinde isekele amabhendi e-NR41 kanye ne-NR42 e-5G.Lolu hloboisandisi sesignaliithuthukiswe ngokukhethekile ukumbozwa kwekheshi, ukuze amakhasimende agcwale indumiso.
Ukuhlaziywa Kwephrojekthi
Manje amaphansi omphakathi aya ngokuya ekhuphuka, futhi ikheshi seliyindlela yokuthutha edingekayo. Nokho, ikheshi.ukusabalala kwesignaliayanele, isignali ibuthakathaka, ngisho nesignali ilahlekile, okuye kwagqiba izingozi zokuphepha kubantu abahamba ngekheshi.Ngakho-ke, izisebenzi zokuphatha kufanele zithuthukise futhi zithuthukise ukumbozwa kwesignali yekheshi ukuze kuqinisekiswe ukuphepha kwabahlali.
Lo msebenzi usesakhiweni esisha eHunan, esihlanganisa amakheshi amabili anezitezi ezingu-20 kanye negumbi elingaphansi.Ngenxa yempendulo ephindaphindiwe yomnikazi yokuthi ilifti ayinawo uphawu, izisebenzi zabaphathi bathole ithimba lika-Lin Chuang okufanele lenze.ukusabalala kwesignali.
Isikimu sokuklama
Sicabangela ukuthi i-lifti floor iyizitezi ezingu-20, futhi ukusetshenziswa kwe-"elevator signal repeater" kubiza izindleko futhi kuyasebenza.
I-elevator ihlukaniswe ngamasethi amabili emishini, iyunithi yokulawula eyinhloko kanye neyunithi yemoto, ngamagama alula: iyunithi yokulawula eyinhloko "ihola" isignali kusukela ngaphandle kuya emgodini we-elevator, futhi iyunithi yemoto idlulisela isignali ye-elevator shaft, emboza ikheshi yonke.
Uhlelo lokuqoqwa komkhiqizo
IkheshiIsiphindaphinda Sesignaliisekela i-2G-5G, ukuthuthukiswa kwesignali yamafrikhwensi amathathu, ifanele ukumbozwa kwesiginali yekheshi ngaphansi kwezitezi ezingama-30, ibhendi yefrikhwensi ethuthukisiwe ihlanganisa i-NR41 ne-NR42, isivinini senethiwekhi “5G” ngempela sishesha kakhulu!Yakhelwe ukumbozwa kwesignali yekheshi, uma yethulwa yanconywa kakhulu.
Inqubo yokufaka
1. Thola indawo ngaphandle lapho umthombo wesignali (amagridi angaphezu kuka-3) muhle (njengesitezi esiphezulu), bese ufaka uthi olutholayo lweyunithi yokulawula enkulu lapha.Uthi olwamukelayo kufanele lubhekane nombhoshongo wesignali.
2.Sebenzisa okokuphakelayo ukuze uxhume uthi lokwamukela lwangaphandle ekupheleni kwesikhulisi se-RF_IN, kanye nokuphela kwe-RF_OUT kwesikhulisi ku-antenna edlulisa ngaphakathi endlini.Hlola ukuthi uxhumano luzinzile.
3.Qinisekisa ukuthi zonke izingxenye zixhunyiwe futhi izixhumi zivikelekile, namandla ku-amplifier.Bese ufaka iyunithi yemoto ngendlela efanayo, futhi isignali yekheshi igcwala ngokushesha!
I-antenna eyamukelayo ifakwa phezulu kwekheshi.
I-antenna yokudlulisa ifakwe ngaphakathi kwekheshi.
Zombili zixhunywe emshinini omkhulu onomphakeli.
4.Ukutholwa kwesignali Ngemva kokufakwa, isofthiwe ye-“CellularZ” isetshenziswa futhi ukuze kutholwe inani lesignali yekheshi, futhi inani le-RSRP liyakhuphuka lisuka ku--116dBm liya ku--78dBm, umphumela wokuthuthukisa uqine kakhulu!
I-RSRP iyinani elijwayelekile lokulinganisa ukuthi isignali ibushelelezi yini, uma sikhuluma nje, ishelela kakhulu ngaphezu kuka -80dBm, futhi empeleni ayikho inethiwekhi engezansi -110dBm.
Ngemva kokufaka umcebo we-elevator, ayikwazi nje ukukhuluma kahle ku-elevator, kodwa futhi ibhulashi imidlalo emifushane yevidiyo, futhi umphumela wokumboza unconywa ngabasebenzi bokuphatha umphakathi!Uma umphakathi wakho nawo unenkinga yesignali, ungashiya imininingwane yakho yokuxhumana ngemuva.
