Nkhaniyi ikupereka mwachidule zamkati mwamagetsi amtundu wobwereza ma siginolofoni. Opanga ochepa amawulula zigawo zamkati za obwereza zizindikiro zawo kwa ogula. Kunena zoona, mapangidwe ndi ubwino wa zigawo zamkatizi zimagwira ntchito yofunika kwambiri pazochitika zonse zafoni yobwerezabwereza.
Ngati mungafune kufotokozera kosavuta momwe foni yobwereza imagwirira ntchito,Dinani apa.
Mfundo Zazikulu Zobwereza Zikwangwani Zam'manja
Monga tawonetsera pachithunzi pamwambapa, mfundo yayikulu yobwereza ma siginecha yam'manja ndikukulitsa ma siginecha pang'onopang'ono. Obwereza ma siginecha amakono pamsika amafunikira magawo angapo okulitsa phindu lotsika kuti akwaniritse zomwe mukufuna. Chifukwa chake, phindu lomwe lili pamwambapa likuyimira gawo limodzi lopindula. Kuti mukwaniritse phindu lomaliza, magawo angapo akukulitsa amafunikira.
Nawa mawu oyamba a ma module omwe amapezeka muzobwereza ma siginolofoni:
1. Signal Reception Module
Module yolandirira imayang'anira kulandira ma siginecha akunja, makamaka kuchokera kumasiteshoni kapena tinyanga. Imagwira ma wayilesi omwe amafalitsidwa ndi siteshoni yoyambira ndikusinthira kukhala ma siginecha amagetsi omwe amplifier amatha kukonza. Module yolandirira nthawi zambiri imakhala:
Zosefera: Izi zimachotsa ma siginecha osafunikira ndikusunga ma frequency ofunikira a mafoni.
Low Noise Amplifier (LNA): Izi zimakulitsa chizindikiro chofooka chomwe chikubwera ndikuchepetsa phokoso lowonjezera.
Zida Zam'kati-mobile sign repeater kunyumba
2. Signal Processing Module
Chigawo chowongolera ma siginecha chimakulitsa ndikusintha chizindikiro cholandilidwa. Nthawi zambiri zimaphatikizapo:
Modulator/Demodulator (Modemu): Izi zimathandizira ndikutsitsa chizindikiro kuti zitsimikizire kuti zikugwirizana ndi njira zoyankhulirana.
Digital Signal processor (DSP): Ili ndi udindo wokonza ma siginecha moyenera ndikuwongolera, kuwongolera mawonekedwe azizindikiro ndikuchepetsa kusokoneza.
Automatic Gain Control (AGC): Imasinthira kupindula kwa siginecha kuti iwonetsetse kuti ikukhalabe m'miyezo yoyenera—kupewa kufooka kwa siginecha komanso kukulitsa mopambanitsa komwe kungayambitse kudzisokoneza kapena kusokoneza zida zina.
3. Kukulitsa Module
Mphamvu ya amplifier (PA) imakulitsa mphamvu ya siginecha kuti iwonjezere kuchuluka kwake. Pambuyo pokonza ma siginecha, chokulitsa mphamvu chimakulitsa chizindikirocho ku mphamvu yofunikira ndikuchitumiza kudzera mu mlongoti. Kusankhidwa kwa amplifier mphamvu kumadalira mphamvu yofunikira ndi malo ophimba. Pali mitundu iwiri ikuluikulu:
Linear Amplifiers: Izi zimasunga mtundu ndi kumveka kwa siginecha popanda kupotoza.
Ma Amplifiers Opanda mzere: Amagwiritsidwa ntchito muzochitika zapadera, nthawi zambiri kuti azitha kufalikira, ngakhale angayambitse kupotoza kwa ma siginecha.
4. Feedback Control and Interference Prevention Modules
Feedback Suppression Module: Pamene amplifier itumiza chizindikiro champhamvu kwambiri, imatha kuyambitsa ndemanga pa mlongoti wolandira, zomwe zimayambitsa kusokoneza. Feedback kupondereza ma modules amathandizira kuthetsa kudzisokoneza uku.
Isolation Module: Imalepheretsa kusokoneza pakati pa kulandira ndi kutumiza ma siginecha, kuwonetsetsa kuti amplifier ikugwira ntchito moyenera.
Kuchepetsa Phokoso ndi Zosefera: Chepetsani kusokoneza kwa chizindikiro chakunja, kuonetsetsa kuti chizindikirocho chimakhala choyera komanso champhamvu.
5. Signal Transmission Module
Transmission Module: Gawoli limatumiza siginecha yokonzedwa ndikukulitsidwa kudzera pa antenna yotumiza kumalo ofikira, kuwonetsetsa kuti zida zam'manja zilandila chizindikiro chokwezeka.
Transmit Power Controller: Imawongolera mphamvu yotumizira kuti ipewe kukulitsa, zomwe zingayambitse kusokoneza, kapena kukulitsa, zomwe zingayambitse zizindikiro zofooka.
Directional Antenna: Kuti muzitha kuyang'ana kwambiri ma siginecha, mlongoti wolozera ungagwiritsidwe ntchito m'malo mwa omnidirectional, makamaka pakuphimba madera akuluakulu kapena kukulitsa ma sign.
6. Power Supply Module
Chigawo Chamagetsi Chamagetsi: Amapereka magetsi okhazikika kwa obwereza ma sigino, makamaka kudzera pa chosinthira cha AC-to-DC, kuwonetsetsa kuti chimagwira ntchito bwino pamagetsi osiyanasiyana.
Power Management Module: Zida zapamwamba zithanso kuphatikizirapo kasamalidwe ka mphamvu kuti muwongolere mphamvu zamagetsi ndikutalikitsa moyo wa chipangizocho.
7. Kutentha Kwambiri Module
Dongosolo Lozizira: Obwereza ma siginecha amapanga kutentha panthawi yogwira ntchito, makamaka ma amplifiers ndi zida zina zamphamvu kwambiri. Dongosolo lozizirira (monga masinki otentha kapena mafani) limathandizira kukhalabe ndi kutentha koyenera kogwira ntchito kuti zisatenthe ndi kuwonongeka kwa chipangizocho.
8. Control Panel ndi Indicators
Control Panel: Ena obwereza ma siginecha am'manja amabwera ndi gulu lowonetsera lomwe limalola ogwiritsa ntchito kusintha masinthidwe, kusintha magwiridwe antchito, ndikuwunika dongosolo.
Zizindikiro za LED : Magetsi awa amasonyeza momwe chipangizochi chikugwirira ntchito, kuphatikizapo mphamvu ya chizindikiro, mphamvu, ndi momwe zimagwirira ntchito, kuthandiza ogwiritsa ntchito kudziwa ngati wobwereza akugwira ntchito moyenera.
9. Madoko olumikizirana
Khomo Lolowetsa: Amagwiritsidwa ntchito polumikiza tinyanga zakunja (mwachitsanzo, zolumikizira zamtundu wa N kapena F).
Output Port: Kulumikiza tinyanga tamkati kapena kutumiza ma siginecha ku zida zina.
Adjustment Port: Ena obwereza amatha kuphatikiza madoko osinthira kupindula ndi ma frequency.
10. Kapangidwe ka Mpanda ndi Chitetezo
Chotsekera chobwerezabwereza chimakhala chopangidwa ndi chitsulo, chomwe chimathandiza kuti chitetezeke ku kusokoneza kwakunja ndikuletsa kusokoneza kwa electromagnetic (EMI). Zipangizo zina zimakhalanso ndi mpanda wosalowa madzi, wosagwira fumbi, kapena wotchingidwa ndi mantha kuti zisapirire panja kapena m'malo ovuta.
Zida Zam'kati-malonda mafoni chizindikiro repeater
Wobwereza ma siginoloji am'manja amathandizira ma siginecha kudzera muntchito yolumikizidwa ya ma module awa. Dongosololi limalandira ndikukulitsa chizindikirocho musanatumize chizindikiro cholimbikitsidwa kudera lothandizira. Posankha chobwereza ma siginecha am'manja, ndikofunikira kuwonetsetsa kuti ma frequency ake, mphamvu, ndikupeza zomwe mukufuna, makamaka m'malo ovuta kwambiri ngati ma tunnel kapena zipinda zapansi pomwe kukana kusokoneza ndi kuwongolera ma siginecha ndikofunikira.
Choncho, kusankhawodalirika wopanga ma signature obwerezandi key.Lintratek, yomwe inakhazikitsidwa mu 2012, ili ndi zaka zoposa 13 pakupanga zizindikiro zobwerezabwereza-kuchokera ku nyumba zogona mpaka zamalonda, kuphatikizapo fiber optic repeaters ndi zoulutsira mwachindunji. Kampaniyo imapanga zida zapamwamba kwambiri pazogulitsa zawo, kuonetsetsa kuti magwiridwe antchito odalirika.
