Imelo kapena kucheza pa intaneti pa ntchito yoyimitsa kamodzi, tidzakupatsirani zisankho zosiyanasiyana zamakina.

Mfundo yogwirira ntchito ya foni yam'manja yolimbikitsa chizindikiro

Foni yam'manja yowonjezera chizindikiro, yomwe imadziwikanso kuti repeater, imakhala ndi tinyanga zoyankhulirana, RF duplexer, amplifier ya phokoso lochepa, chosakanizira, ESC attenuator, fyuluta, amplifier mphamvu ndi zigawo zina kapena ma modules kuti apange maulalo a uplink ndi downlink amplification.

Foni yam'manja chizindikiro cholimbikitsa ndi chinthu chopangidwa mwapadera kuti chithetse mawonekedwe akhungu amtundu wa foni yam'manja.Popeza ma foni am'manja amadalira kufalikira kwa mafunde amagetsi kuti akhazikitse kulumikizana, chifukwa cha kutsekeka kwa nyumba, m'nyumba zina zazitali, zipinda zapansi ndi malo ena, malo ogulitsira, malo odyera, malo osangalatsa monga karaoke, sauna ndi kutikita minofu, mobisa. ntchito zoteteza mpweya wa anthu, masiteshoni apansi panthaka, ndi zina zambiri, m'malo awa, ma siginecha amafoni am'manja sangathe kufika ndipo mafoni a m'manja sangathe kugwiritsidwa ntchito.

Lintratek foni yam'manja yowonjezera chizindikiroakhoza kuthetsa mavutowa bwino kwambiri.Malingana ngati foni yam'manja yowonjezera chizindikiro cha foni imayikidwa pamalo enaake, anthu amatha kulandira chizindikiro chabwino cha foni paliponse pamene mukuphimba dera lonselo.Nachi chithunzi chongowonetsa momwe chilimbikitso cha mafoni chimagwirira ntchito.

foni yam'manja chizindikiro cholimbikitsa

Mfundo yofunikira pa ntchito yake ndi: gwiritsani ntchito mlongoti wakutsogolo (mlongoti wopereka) kuti mulandire chizindikiro chotsikirapo cha siteshoni yoyambira mu chobwerezabwereza, kukulitsa chizindikiro chothandizira kudzera pa amplifier ya phokoso lotsika, kupondereza chizindikiro cha phokoso mu siginecha, ndikuwongolera. chiŵerengero cha signal-to-noise (chiŵerengero cha S/N).);Kenako imasinthidwa kukhala siginecha yapakati, yosefedwa ndi fyuluta, yokulitsidwa pafupipafupi, kenako imasinthidwa kukhala ma frequency a wailesi ndikusintha pafupipafupi, kukulitsidwa ndi chokulitsa mphamvu, ndikutumizidwa ku siteshoni yam'manja ndi mlongoti wakumbuyo. (retransmission mlongoti);nthawi yomweyo, mlongoti wakumbuyo umagwiritsidwa ntchito.Chizindikiro cha uplink cha siteshoni yam'manja chimalandiridwa, ndipo chimakonzedwa ndi ulalo wa uplink amplification motsatira njira ina: ndiye kuti, imatumizidwa ku siteshoni yoyambira kudzera pa phokoso lochepa la amplifier, downconverter, fyuluta, amplifier yapakati, ndi upconverter, ndi amplifier mphamvu.Ndi mapangidwe awa, kulumikizana kwanjira ziwiri pakati pa siteshoni yoyambira ndi siteshoni yam'manja kungakhale kotheka.

Malangizo oyika ndi chenjezo:

1. Kusankhidwa kwachitsanzo: Sankhani chitsanzo choyenera malinga ndi kuphimba ndi zomangamanga.

2. Dongosolo logawa mlongoti: Gwiritsani ntchito tinyanga ta Yagi panja, ndipo mayendedwe a tinyanga akuyenera kuloza potengera potengera momwe mungathere kuti mukwaniritse bwino kulandirira.Tinyanga za Omnidirectional zitha kugwiritsidwa ntchito m'nyumba, ndipo kutalika kwake ndi 2-3 metres (Kuchuluka kwa mlongoti ndi malo zimadalira malo amkati ndi m'nyumba), mlongoti umodzi wokha wamkati uyenera kuyikiridwa kuti ukhale wosatsekeka wamkati wosakwana 300 masikweya. mamita, tinyanga 2 zamkati zimafunikira pa masikweya mita 300-500, ndipo 3 zimafunikira pamitundu yosiyanasiyana ya 500 mpaka 800 masikweya mita.

3. Foni yam'manja chizindikiro chilimbikitso unsembe: zambiri anaika pa oposa 2 mamita pamwamba pa nthaka.Mtunda wapakati pa malo oyika zida ndi tinyanga zamkati ndi zakunja uyenera kuyendetsedwa ndi mtunda waufupi kwambiri (ndi chingwe chachitali, kutsitsa kwamphamvu kwambiri) kuti mukwaniritse bwino.

4. Kusankhidwa kwa mawaya: muyezo wa feeder ya chowonjezera chizindikiro cha wailesi ndi wailesi yakanema (ndi chingwe TV) ndi 75Ω, koma foni yam'manja yolumikizirana ndi makampani olankhulana, ndipo muyezo wake ndi 50Ω, ndipo kusokoneza kolakwika kudzachitika. kuwononga zizindikiro za dongosolo.Kuchuluka kwa waya kumatsimikiziridwa malinga ndi momwe zilili pa malo.Chingwecho chitalikira, ndiye kuti waya wokhuthala kuti achepetse kutsika kwa siginecha.Kugwiritsa ntchito waya wa 75Ω kuti mupangitse wolandirayo ndi waya asagwirizane kumawonjezera kuyimirira ndikuyambitsa zovuta zosokoneza.Choncho, kusankha kwa waya kuyenera kukhala kosiyana malinga ndi makampani.

Chizindikiro chotumizidwa ndi mlongoti wamkati sichikhoza kulandiridwa ndi mlongoti wakunja, zomwe zingayambitse kudzisangalatsa.Nthawi zambiri, tinyanga ziwirizi zimasiyanitsidwa ndi mita 8 kuti tipewe kudzisangalatsa.

Lintratek, thetsani mwaukadaulo zovuta zamawu a foni yam'manja!ChondeLumikizanani nafekwa kasitomala.
