Indlela yokufeza iukufakwa kwesignali yomkhumbi, isignali egcwele endlini?
I-Offshore Oil Support Vessel, isikhathi eside kude nomhlaba futhi ijule olwandle.Okubaluleke kakhulu ukuthi azikho izimpawu emkhunjini, abakwazi ukuxhumana nemindeni yabo, okubangela ukuphazamiseka empilweni yabasebenzi!
1.Imininingwane Yephrojekthi
Le phrojekthi ingeyokumboza isignali yemikhumbi yokusekela uwoyela yasogwini, isamba semikhumbi emi-2, ngayinye inamadekhi ama-4.Imikhumbi esekela uwoyela wasogwini iyimikhumbi ezinikele yokuhlola uwoyela negesi yasogwini, ukuthuthukiswa, nokukhiqizwa, ngokuvamile ekude nomhlaba kanye nasekujuleni kolwandle.Ngenxa yesimo sokusebenza kanye nesakhiwo esikhethekile, ngokuvamile akubi khona isignali ekhabetheni, futhi izimpilo zabasebenzi ziphazamisa kakhulu.
Umuntu ophethe iphrojekthi uthe: isignali ku-cabin yimbi kakhulu, asikho isignali lapho ukusebenza kolwandle kujwayelekile, kodwa asikho isignali lapho ugu lugcwaliswa kabusha, futhi ngithemba ukuxazulula inkinga yamanethiwekhi amathathu. .
2.I-Design Scheme
Indawo yokumboza amasignali yiphaseji lekhabethe, umhubhe wezitezi ezi-4 ungamamitha angama-440, futhi imikhumbi emibili ingamakhilomitha acishe abe ngamamitha.
3.Uhlelo lokuqoqwa komkhiqizo
Ngokusetshenziswa kwe-cabin engqondweni, i-isandisi sesignaliI-KW35A ikhethiwe.I-KW35A inomzimba wensimbi ongangeni manzi futhi ongenawo umswakama, ukunqanyulwa kokushisa okusebenzayo, ofaneleka kakhulu kumagumbi angaphansi, amahubhu, iziqhingi, amakhabhini nezinye izigcawu eziyinkimbinkimbi.I-antenna enkulu yelogi kanye ne-plastic steel omnidirectional antenna kwakhethwa ukuze kutholwe izimpondo, ezazithatha indawo yodwa.I-antenna enkulu yelogi yasetshenziswa ngenkathi umkhumbi umile, kanye nei-antenna ye-omnidirectionalyashintshwa lapho kuhamba ngomkhumbi.
4.Ifakwa kanjani?
Isinyathelo sokuqala, faka i-antenna ethola ngaphandle: I-antenna eyamukelayo ifakwe endaweni ephakeme yomkhumbi, futhi i-plastic steel omnidirectional antenna ingathola isignali engu-360 °, efanelekile ukusetshenziswa olwandle;I-antenna ye-Logarithmic inemikhawulo yokuqondisa, kodwa umphumela wokwamukela ungcono, futhi ilungele ukusetshenziswa lapho imikhumbi ima ukuze inikeze futhi.
Isinyathelo sesibili, Ukufakwa kwe-antenna yasendlini
Ukufakwa kwezintambo kanye nokufakwa kwe-antenna ku-cabin.
Isinyathelo sesithathu, xhumana nesiphindaphinda isignali.
Hlola ukuthi izinti ezamukelayo nezizithumelayo zifakiwe yini ngaphambi kokuzixhuma kumsingathi.Uma kungenjalo, umsingathi angase alimale.
Isinyathelo sokugcina, hlola isignali.
Ngemva kokufakwa, isofthiwe ye-“CellularZ” iphinde yasetshenziswa ukuze kutholwe inani lesignali yekhabhinethi, futhi inani le-RSRP lanyuswa lisuka ku--115dBm laya ku-89dBm, umphumela wokumboza wawuqine kakhulu!
Ngaphambi kokufakwa Ngemva kokufakwa
(I-RSRP iyinani elijwayelekile lokulinganisa ukuthi isignali ibushelelezi, uma sikhuluma nje, ishelela kakhulu ngaphezu kuka--80dBm, futhi ayikho inethiwekhi ngezansi -110dBm).
