40-50 km kude nedolobha, isignali ifinyelela ogwadule lwase-Inner Mongolia. Ungakuthola kanjani ukumbozwa ngebanga elide kangaka? Imishini ye-booster yesiginali nayo idinga ukuthi ingangeni manzi, ivikele isihlabathi, futhi imelane namazinga okushisa aphezulu kakhulu?
Okokuqala IImininingwane Yephrojekthi
| I-Mongolia yangaphakathiDfakaSi-ignalCukweqile | |
| Indawo Yephrojekthi | I-Mongolia yangaphakathi, China |
| Ubude Bekhava | 4000Imitha yesikwele |
| Uhlobo Lwephrojekthi | IbhizinisiSebenzisa |
| Iphrofayili Yephrojekthi | Amakhilomitha angamashumi ukusuka edolobheni, indawo yokuhlola cishe ayinawo amasignali |
| CumqaphiDemand | Amasiginali athuthukisiwe omakhalekhukhwini kanye nomakhalekhukhwini we-Unicom, ukusabalala kwesignali yenhlolovo. |
Ngenxa yephrojekthi yangaphambilini yokuhlola uwoyela e-Gansu nase-Bohai, umphumela wokumbozwa kwesignali muhle kakhulu! Siphinde sathola ukumbozwa kwezimpawu ezivela ezindaweni ezimbili zokuhlola uwoyela e-Inner Mongolia Desert/Gobi Desert.
Inhlolovo itholakala ogwadule lwe-Inner Mongolia/Gobi desert deep, isamba sezindawo zokuhlola ezimbili, ngalinye lilinganiselwa ku-2000 square metres. Imvelo ezungezile inokhahlo, ngokuvamile ihambisana nesihlabathi, izinga lokushisa eliphezulu kanye nezinkinga ezishisayo.Kusuka edolobheni eliseduze amakhilomitha angu-40-50, okuhlanganisa izibonakaliso ezintathu zokuqala zenethiwekhi azitholakali, ayikwazi ukusebenzisa noma yimaphi amathuluzi okuxhumana.
Ukutholwa Kwesiginali Ngaphambi Kwembondela
Sibona izimpawu phezulu kwezindunduma zesihlabathi ezizungezile. Ekugcineni, isignali yokuxhumana eshelelayo yatholwa phezulu kwezindunduma eziphakeme eziqhele ngamakhilomitha angu-3, ne-RSRP engaba ngu- -100dBm.
(I-RSRP iyinani elijwayelekile lokulinganisa ukuthi isignali ibushelelezi, uma sikhuluma nje, ishelela kakhulu ngaphezu kuka--80dBm, futhi ayikho inethiwekhi engezansi -110dBm.
Okwesibili IDukusayinaSikhemi
Iphrojekthi idinga ukuxazulula izinselelo ezintathu:
1, ibanga ukusuka kukhava likude kakhulu, ukunikezwa kwamandla akulungile.
I-2, ibanga lokumboza likude kakhulu, inkinga yokulahlekelwa kwesignali.
3, indawo ewugwadule inokhahlo, idinga uthuli, amanzi, ukumelana nokushisa okuphezulu nokunye ukusebenza.
Uhlelo lokuqoqwa komkhiqizo
Ngesimo sephrojekthi,Eyethu Iqembu likhethe i-20W optical fiber repeater enothi olukhulu lwepuleti.
I-optical fiber repeater ingafinyelela ukudluliswa kwesignali yebanga elide, futhi inqubo yokudlulisela ngokuyisisekelo ayilahleki. Igobolondo le-chassis liklanywe nge-alloy ye-aluminium eqinile engangeni manzi futhi enothuli, engesabi indawo yasogwadule enzima futhi emboza kalula izinkulungwane zamamitha-skwele!
I-antenna yepuleti elikhulu ikhethiwe ukuze yamukelwe futhi idluliselwe. I-antenna yepuleti elikhulu inezinzuzo zokuzuza okuphezulu, amandla amakhulu, iphethini yomkhakha omuhle, ukusebenza okuthembekile kokubeka uphawu nempilo ende yesevisi, futhi ifanelekela ugwadule, izintaba nezinye izindawo ezinkulu ezihlanganisa izindawo.
Ngenxa yokuphazamiseka kokunikezwa kwamandla ogwadule lwaseGobi, ukukhiqizwa kwamandla kagesi we-solar photovoltaic okwengeziwe kungaxazulula ngokuphelele inkinga yokufakwa kwesignali.
Okwesine I Ukufakwa
1. Faka uthi olwamukelayo futhii-fiber optical eseduze ekupheleni ophindayo:
I-antenna yepuleti elikhulu kanye nomshini we-fiber optical oseduze ekupheleni kufakwe phezulu kwendunduma eqhele ngamakhilomitha amathathu. Ukushelela kwesignali evela endaweni yokwamukela, kuba ngcono umphumela wokumboza isignali.
2. Fakaing i-antenna yepuleti elikhulu kanye ne-remote optical fiberophindayo:
Fakaing i-antenna yepuleti elikhulu kanye nomshini we-fiber optical okude eduze nendawo yokuhlola. Ngenxa yemvelo eqondisayo ye-antenna yepuleti elikhulu, ukufakwa kufanele kubheke endaweni yokumboza isignali.
Hlola ukuthi izinti ezamukelayo nezizithumelayo zifakiwe yini ngaphambi kokuxhuma umshini wefiber optical. Kungenjalo, theophindayo ingase yonakale.
- Ukuhlolwa Kwesiginali:
Ngemva kokufaka, isofthiwe ye-“CellularZ” isetshenziswa futhi ukuze kutholwe inani lesignali, futhi inani lesignali yeselula ne-unicom ngemva kokufakwa ngu--83dBm kuya ku- -89dBm, umphumela wokuhlanganisa usobala kakhulu!
Amacala okuhlanganisa amasignali ukusuka e-Gansu Bohai kuya e-Inner Mongolia, kwanele ukufakazela ukuthi ikhwalithi nensizakalo ye-Lintratek amplifiers yesignali ayinasici.
I-Lintratek Signal Repeater kusuka ocwaningweni nasekuthuthukisweni kuya ekukhiqizeni, lawula ngokuqinile inqubo ngayinye yokukhiqiza. I-amplifier yesiginali ngayinye ifakwe amaqembu amaningana amamojula e-anti-interference kanye ne-anti-corrosion alloy body, bese emva kokushisa okuphezulu nokuphansi, ubufakazi bokushaqeka, ukuvikela amanzi, ukuhlolwa kokuguga ukuze kuqinisekiswe ukuthi ingasetshenziswa ezindaweni ezimbi kakhulu ezifana nezingwadule nemigudu. .
