Isignali yelifti enezitezi ezingu-20, isethi “yelifti”isiphindaphindi sesiginali"ukuxazulula inkinga yokumbozwa okugcwele. Iphinde isekele amabhendi e-NR41 kanye ne-NR42 e-5G. Lolu hlobo lweisikhulisi sesiginaliyakhelwe ngokukhethekile ukumbozwa kwe-lifti, ukuze amakhasimende agcwale udumo.
Ukuhlaziywa Kwephrojekthi
Manje izitezi zomphakathi ziya ziphakama, futhi ilifti isibe yindlela edingekayo yokuhamba. Kodwa-ke, iliftiukumbozwa kwesiginaliakwanele, isignali ibuthakathaka, futhi ngisho nesignali ilahlekile, okuye kwafihla izingozi zokuphepha kubantu abagibela ilifti. Ngakho-ke, abasebenzi bokuphatha kufanele bathuthukise futhi bathuthukise ukumbozwa kwesignali yelifti ukuqinisekisa ukuphepha kwezakhamuzi.
Lo msebenzi utholakala esakhiweni esisha eHunan, esihlanganisa ama-lifti amabili anezitezi ezingu-20 kanye negumbi elingaphansi. Ngenxa yempendulo ephindaphindwayo yomnikazi yokuthi i-lifti ayinasiginali, abasebenzi bokuphatha bathole ithimba likaLin Chuang ukuthi likwenze.ukumbozwa kwesiginali.
Uhlelo lokuklama
Siyaqaphela ukuthi iphansi le-lifti linezitezi ezingu-20, futhi ukusetshenziswa kwe-“elevator signal repeater” kuyabiza futhi kuyasebenza.
I-lifti ihlukaniswe ngamasethi amabili emishini, iyunithi yokulawula eyinhloko kanye neyunithi yemoto, ngamagama alula: iyunithi yokulawula eyinhloko "ihola" isignali isuka ngaphandle iye ku-lifti, bese iyunithi yemoto idlulisela isignali ye-lifti, imboze lonke i-lifti.
Uhlelo lokuhlanganisa umkhiqizo
IliftiIsiphindaphindi SesignaliIsekela i-2G-5G, ukuthuthukiswa kwesignali yamaza amathathu, efanelekile ukumbozwa kwesignali ye-elevator ngaphansi kwezitezi ezingu-30, ibhendi yemvamisa ethuthukisiwe ifaka i-NR41 ne-NR42, isivinini senethiwekhi "ye-5G" sishesha kakhulu! Yakhelwe ukumbozwa kwesignali ye-elevator, uma isiqalisiwe yanconywa kakhulu.
Inqubo Yokufaka
1. Thola indawo ngaphandle lapho umthombo wesiginali (amagridi angaphezu kwama-3) umuhle khona (njengesitezi esiphezulu), bese ufaka i-antenna yokwamukela yeyunithi yokulawula eyinhloko lapha. I-antenna yokwamukela kumele ibheke embhoshongweni wesiginali.
2.Sebenzisa i-feeder ukuxhuma i-antenna yokwamukela yangaphandle ekugcineni kwe-RF_IN kwe-amplifier, kanye ne-RF_OUT ekugcineni kwe-amplifier kwi-antenna yokudlulisa yangaphakathi. Hlola ukuthi uxhumano luzinzile.
3.Qinisekisa ukuthi zonke izingxenye zixhunyiwe futhi izixhumi ziqinile, futhi zivule i-amplifier. Bese ufaka iyunithi yemoto ngendlela efanayo, bese isignali ye-elevator igcwala ngokushesha!
I-antenna yokwamukela ifakwe phezulu kwe-elevator.
I-antenna edlulisa ugesi ifakwe ngaphakathi kwe-elevator.
Zombili zixhunywe emshinini oyinhloko nge-feeder.
4. Ukutholwa Kwesignali Ngemva kokufakwa, isofthiwe ethi “CellularZ” isetshenziswa futhi ukuthola inani lesignali ye-elevator, futhi inani le-RSRP liyakhushulwa lisuka ku--116dBm liye ku--78dBm, umphumela wokuthuthukisa unamandla kakhulu!
I-RSRP iyinani elijwayelekile lokulinganisa ukuthi isignali ibushelelezi yini, ngokuvamile, ibushelelezi kakhulu ngaphezu kwe--80dBm, futhi empeleni ayikho inethiwekhi engaphansi kwe--110dBm.
Ngemva kokufaka ingcebo yelifti, ayikwazi ukukhuluma kahle kuphela e-lifti, kodwa futhi ikwazi nokudlala imidlalo emifushane yevidiyo, futhi umphumela wokumboza uyanconywa ngabasebenzi bokuphatha umphakathi! Uma umphakathi wakho nawo unenkinga yesignali, ungashiya imininingwane yakho yokuxhumana ngemuva.
