Isiginali yelifti yomgangatho engama-20, iseti "yelifti"isiphindaphindi sesiginali"ukusombulula ingxaki yokugubungela ngokupheleleyo. Ikwaxhasa iibhendi ze-NR41 kunye ne-NR42 ze-5G. Olu hloboisandisi-lizwiyenzelwe ngokukodwa ukugubungela ilifti, ukuze abathengi bazaliswe ludumo.
Uhlalutyo lweProjekthi
Ngoku umgangatho woluntu uya uphakama, kwaye ilifti iye yaba yindlela efunekayo yokuthutha. Nangona kunjalo, iliftiukugquma isignaliawanelanga, isignali ibuthathaka, kwaye nesignali ilahlekile, nto leyo eye yafihla iingozi zokhuseleko kubantu abakhwela ilifti. Ke ngoko, abasebenzi bolawulo kufuneka baphucule kwaye baphucule ukugqunywa kwesignali yelifti ukuqinisekisa ukhuseleko lwabahlali.
Le projekthi ikwisakhiwo esitsha eHunan, esigubungela iilifti ezimbini ezinezitezi ezingama-20 kunye negumbi elingaphantsi komhlaba. Ngenxa yengxelo ephindaphindiweyo yomniniyo yokuba ilifti ayinasiginali, abasebenzi bolawulo bafumene iqela likaLin Chuang ukuba lenze njalo.ukugquma isignali.
Inkqubo yoyilo
Sicinga ukuba umgangatho welifti unemigangatho engama-20, kwaye ukusetyenziswa kwe-"elevator signal repeater" kubiza kancinci kwaye kuyasebenza.
Ilifti yahlulwe yaba ziiseti ezimbini zezixhobo, iyunithi yokulawula ephambili kunye neyunithi yemoto, ngamazwi alula: iyunithi yokulawula ephambili "ikhokela" isignali ukusuka ngaphandle ukuya kwi-lifti shaft, kwaye iyunithi yemoto idlulisela isignali ye-lifti shaft, igubungela i-lifti yonke.
Inkqubo yokudibanisa iimveliso
IliftiIsiphindaphindi seSignaliIxhasa i-2G-5G, ukuphuculwa kwesignali ye-frequency ezintathu, ifanelekile ukugqunywa kwesignali ye-elevator ngaphantsi kwemigangatho engama-30, ibhendi ye-frequency ephuculweyo ibandakanya i-NR41 kunye ne-NR42, isantya senethiwekhi "ye-5G" sikhawuleza kakhulu! Yenzelwe ukugqunywa kwesignali ye-elevator, yakuba iqalisiwe yanconywa kakhulu.
Inkqubo yoFakelo
1. Fumana indawo engaphandle apho umthombo wesiginali (ngaphezulu kwegridi ezi-3) ulungile khona (njengomgangatho ophezulu), kwaye ufake i-antenna yokwamkela yeyunithi yokulawula ephambili apha. I-antenna yokwamkela kufuneka ijonge kwinqaba yesiginali.
2.Sebenzisa i-feeder ukuqhagamshela i-antenna yangaphandle efumana umbane kwisiphelo se-RF_IN se-amplifier, kunye nesiphelo se-RF_OUT se-amplifier kwi-antenna ethumela umbane ngaphakathi. Qinisekisa ukuba unxibelelwano luzinzile.
3.Qinisekisa ukuba zonke izinto ziqhagamshelwe kwaye izihlanganisi ziqinile, kwaye uvula i-amplifier. Emva koko faka iyunithi yemoto ngendlela efanayo, kwaye isignali yelifti igcwala ngoko nangoko!
I-antenna yokwamkela ifakwe phezulu kwilifti.
I-antenna ethumelayo ifakwe ngaphakathi kwilifti.
Ezi zimbini ziqhagamshelwe kumatshini oyintloko ngesixhobo sokutya.
4. Ukufunyanwa kweSignali Emva kokufakwa, isoftware ethi “CellularZ” isetyenziswa kwakhona ukufumanisa ixabiso lesignali yelifti, kwaye ixabiso le-RSRP linyuswa ukusuka kwi--116dBm ukuya kwi--78dBm, isiphumo sokuphucula sinamandla kakhulu!
I-RSRP lixabiso eliqhelekileyo lokulinganisa ukuba isignali igudile na, ngokubanzi, igudile kakhulu ngaphezu kwe-80dBm, kwaye akukho nethiwekhi ingaphantsi kwe-110dBm.
Emva kokufaka ubutyebi be-lifti, ayinakuthetha kakuhle kuphela kwi-lifti, kodwa ikwanokudlala imidlalo yevidiyo emifutshane, kwaye isiphumo sokugubungela siyanconywa ngabasebenzi bolawulo loluntu! Ukuba uluntu lwakho lunengxaki yesignali, ungashiya ulwazi lwakho loqhagamshelwano ngasemva.
