Mungakhalebe ndi chikaiko: kodi zida za wailesizi zimagwirira ntchito limodzi bwanji? Timve kuchokera kugulu laukadaulo la FMUSER!

Kufunika Kwakukula Kwawayilesi wa FM Radio mu 2021

Chotsatira ndi Kodi FM Broadcast Transmitter Imagwira Ntchito Motani? | Dinani apa

Chidziwitso chawayilesi chomwe chimafalitsidwa ndi wailesi ya FM radio transmitter chimagwira ntchito yofunika kwambiri pakugwiritsa ntchito intaneti yothamanga kwambiri komanso ukadaulo wamafoni. Makamaka pakali pano, mliri wapadziko lonse ukuchulukirachulukira. Ntchito zowulutsa pawayilesi zopanda contactless monga lowetsa-mu mpingo ndi drive-in theatre atsimikiziranso makhalidwe awo. 

Pakuchulukirachulukira mu 2021 kwa ntchito zowulutsa pawailesi ya FM padziko lonse lapansi, Mawayilesi ambiri a FM adakhalapo, zomwe zidapangitsanso opanga zida zambiri zamawayilesi. kuzindikira kuti mliriwu wakhala woyendetsa wamkulu wa zida zowulutsira pawailesi padziko lonse lapansi, zomwe ndi zokwanira kutsimikizira izi kwa iwo. ogulitsa zida zowulutsira pawayilesi, ogulitsa zida zowulutsira pawayilesi kapena ogwira ntchito pawayilesi ya FM, chowulutsira mawayilesi a FM ndi chimodzi mwazinthu zofunikira kwambiri komanso zofunika kwambiri pamawayilesi apawayilesi. ndipo zowonadi, ndi zida zopindulitsa kwambiri pawayilesi pabizinesi yayikulu.

Chotsatira ndi Zosiyana Pakati pa Zotumiza Zamunthu ndi Zamalonda za FM | Dinani apa

Anthu ambiri a Google funso ili, koma zotsatira zake zambiri zikuwoneka zovuta. M'malo mwake, ma transmitters a wailesi amapanga chizindikiro chonyamulira pafupipafupi pafupipafupi kudzera pa oscillator, ndiyeno chizindikiro cha FM chimafalikira kudzera mu FM mlongoti ku mlengalenga. Dziwani kuti pamene chizindikiro chapadera chiyenera kuyendetsedwa, makina opangira magetsi amagwiritsidwa ntchito. Popanda a FM module, chizindikiro chafupipafupi chimaperekedwa pamtundu wodziwika bwino. 

Mwachidziwitso, makina opangira ma radio transmitter amadalira oscillator, chifukwa oscillator ndi chipangizo chopangira chizindikiro chonyamulira. Kuphatikiza pa oscillator, palinso chipangizo chamagetsi choperekera chizindikiro chamagetsi, chosinthira chowonjezera chidziwitso kwa chonyamulira, amplifier chowonjezera mphamvu yonyamula, ndi mlongoti wosinthira chizindikirocho kukhala mafunde a wailesi.

Kuchokera kumapeto kwa ma wayilesi, sikovuta kuwona mayendedwe athunthu awayilesi:

1. Mphamvu yamagetsi imathandizira chowulutsira mawayilesi kuti apeze chizindikiro chamagetsi. Pakadali pano, titha kusintha ma frequency knobs ndi makiyi ena kuti agwiritse ntchito chowulutsira
2. Oscillator imapanga magetsi osinthika. Njira yosinthira yomwe imapangidwa ndi oscillator imatchedwa mafunde onyamula.
3. The modulator adzawonjezera zambiri kwa mafunde chonyamulira. Modulator imachulukitsa pang'ono kapena kuchepetsa ma frequency a chonyamulira (pokhala ndi FM), pomwe mu transmitter ya AM, matalikidwe a chonyamuliracho amasiyana molingana ndi siginecha yosinthidwa.
4. RF amplifier idzawonjezera mphamvu ya mafunde onyamula. Kulimba kwa amplifier mu transmitter, m'pamenenso kufalikira kumaloledwa ndi wailesiyi.
5. Dongosolo lofananira (chochunira cha mlongoti) limasamutsa mphamvu ku mlongoti pofanizira cholumikizira chotsekereza ku mlongoti (kapena chingwe cholumikizira bwino ku mlongoti). Ngati zopinga izi sizili zofanana, zimabweretsa vuto lomwe limatchedwa mafunde oyimirira, momwe mphamvu imawonekeranso kuchokera ku mlongoti kupita ku transmitter ndikuwonongeka, nthawi zina chowulutsira chowulutsa chimatha kutenthedwa ndikusweka.
6. Antenna yowulutsa idzasintha siginecha yokwezeka kukhala mafunde a wailesi. Wailesi yokhala ndi nsanja yolimba yowulutsira imatha kukhala ndi kuwulutsa kwabwinoko.
7. Phokoso likasinthidwa kukhala mafunde a sine ndikufalitsidwa, njira yotumizira ma wayilesi imachitika. Kutalika kwa sine wave kumasinthidwa ndikusintha pafupipafupi kuti mutumize kwa wolandila FM.
8. Chodziwira mu wailesi kenako chimatembenuza sine wave chawayilesi kukhala chomveka, ndipo chokulitsa mawu chimakulitsa mphamvu yake.

Ngati mwaphunzira za gulu la zida zamawayilesi ndi mfundo zawo zogwirira ntchito m'mbuyomu, mudzadziwa kuti mapulogalamu omvera omwe amawulutsidwa pawailesi amadutsa munjira yowoneka ngati yovuta koma yosavuta.

Chizindikirocho chimayamba ulendo wake ngati mawonekedwe a sine wave. Ulendo wake utayamba, munalibe chidziwitso chobisika mmenemo. Chidziwitso chikalandira chizindikiro cha electromagnetic, chimajambulidwa. Mafunde a electromagnetic amenewa ndi amphamvu kuposa mafunde opangidwa ndi makina chifukwa amatha kudutsa pamalo opanda kanthu pa liwiro la kuwala. FM imayimira kusinthasintha pafupipafupi, zomwe zikutanthauza kuti imatha kutulutsa mawu kuchokera komwe kumachokera. Ichi ndichifukwa chake ma wayilesi a FM amatha kusewera nyimbo zapamwamba kwambiri.

Nthawi zina sitimva wailesi. Uku ndikulephera kufalikira komwe kumachitika chifukwa chakufupika kwafunde. Mafunde aafupi amayenda molunjika kutali ndi kutsetsereka kwa dziko lapansi. Chifukwa chakuti dziko lapansi ndi lozungulira, chizindikirocho chidzasokonezedwa. Nthawi zambiri, mapiri, nyumba zazitali, komanso kutalika kwa ma antennas owulutsa ma FM kumatha kukhala zinthu zomwe zimalepheretsa kufalikira kwa ma wayilesi panthawi yotumizira ma wayilesi.
