Mashandiro anoita mamodule eredhiyo pakuzviitira wega
Nhepfenyuro ndeimwe yezvinhu zvakakosha zvikuru munhoroondo yemazuva ano, ichitamba basa rakakosha mukutaurirana muzana remakore rechi20 kusvika nhasi. Kune vanofarira zvemagetsi neDIY, kunzwisisa mashandiro anoita radio module kunogona kuva basa rinonakidza uye rinonetsa. Muchinyorwa chino, tichatsanangura mashandiro anoita radio module, iyo inogona kushandiswa kune akasiyana mapurojekiti eDIY.
Nhanganyaya kuRadio Modules
Module yeredhiyo chinhu chemagetsi chinobvumira kugamuchira kana kutumira masaini eredhiyo. Mamodule aya anowanzo batanidzwa mumidziyo yakaita seredhiyo dzeFM, maremote control, uye masisitimu ekutaurirana asina waya. Mamodule eredhiyo anogona kukamurwa kuita mapoka maviri makuru: mareceiver nematransmitter.
Redhiyo inogamuchira mafungu eredhiyo anotumirwa nemhepo yoashandura kuita ruzha kana data, ukuwo redhiyo inotumira mafungu aya. Mamodule aya eredhiyo anoshanda pamafrequencies akasiyana-siyana anodzorwa nemasangano anotonga.
Zvikamu Zvikuru zveRedhiyo Receiver
Kunzwisisa mashandiro anoita radio module kunosanganisira kuziva zvinhu zvakakosha zvinosanganisira:
1. Antena:
Antena chinhu chinobata masaini eredhiyo kubva mumhepo. Inogona kuva waya refu kana tsvimbo yesimbi yakagadzirirwa kugamuchira frequency chaiyo.
2. Mugadziri:
Tuner ine basa rekusarudza mafrequency chaiwo kubva kuradio spectrum. Vagamuchiri veredhiyo vanowanzo shandisa tuner kuparadzanisa chiratidzo chaunoda kubva kupombi yesignali yakagamuchirwa.
3. Demodulator:
Kana chiratidzo chasarudzwa netuner, demodulator inochigadzirisa kuti ibudise ruzivo rwuri mairi. Kubviswa uku kwakakosha pakushandura ma frequency (FM) kana amplitude (AM) modulation signals kuita odhiyo kana data rinoshanda.
4. Chinosimudzira Manzwi:
Masaini akaderedzwa anowanzova asina simba zvekuti haakwanise kushandiswa zvakananga, zvichireva kuti anoda kuwedzerwa simba. MaAmplifiers anowedzera simba remasaini aya kuitira kuti agone kushandiswa mumabasa akasiyana-siyana, kusanganisira kutamba odhiyo.
Zvikamu Zvikuru zveRadio Transmitter
Maredhiyo anotumira zvinhu ane zvikamu zvakasiyana, zvinosanganisira:
1. Jenareta yeMasaini (Oscillator):
Oscillator inogadzira chiratidzo chine mafrequency akawanda chinofanira kutumirwa. Mafrequency aya anosarudza kureba kwewavelength yechiratidzo cheredhiyo chinotumirwa.
2. Modulator:
Basa remugadziri wemagetsi nderekubatanidza chiratidzo cheruzivo nechiratidzo chemutakuri chinobva kuoscillator. Kune nzira dzakasiyana-siyana dzekushandura, dzakadai seFrequency Modulation (FM), Amplitude Modulation (AM), uye Phase Modulation (PM).
3. Chinosimudzira Manzwi:
Sezvinoita neanogamuchira, amplifier iri mutransmitter inowedzera simba remasaini kuitira kuti ikwanise kusvika kure zvakanyanya kana ichitumirwa kuburikidza neantenna.
4. Antena:
Antena yemuchina wekutumira mashoko ndiyo inoburitsa chiratidzo cheredhiyo mumhepo. Dhizaini yeantena inokanganisa kushanda kwemuchina wekutumira mashoko.
Mashandiro anoita maRadio Modules muzvirongwa zveDIY
Iye zvino tichatsanangura mashandiro anoita module yeredhiyo kana tichitarisa chirongwa cheDIY. Ngatitorei muenzaniso wekugadzira redhiyo yeFM iri nyore.
1. Kusarudzwa kweZvikamu:
Danho rekutanga nderekusarudza zvinhu zvinodiwa, zvinosanganisira FM antenna, FM tuner IC (semuenzaniso, TDA7000), ma capacitor, resistors, uye maspika.
2. Kuunganidza Bhodhi reDunhu:
Antena yakabatana neinternet yeFM tuner IC. Tuner iyi inobva yabatanidzwa kune demodulator iri mukati meIC kuti ibudise chiratidzo cheaudio. Chiratidzo cheaudio chinozowedzerwa uchishandisa transistor-based amplifier kana imwe IC isati yapihwa kune speaker.
3. Gadzirisa Mafambiro:
Purojekiti iyi inoda kugadziriswa kwema frequency kuti itore FM station yaunoda. Izvi zvinogona kuitwa uchishandisa potentiometer yakabatana ne tuning input ye tuner IC.
4. Kuedza uye Kugadzirisa:
Mushure mekugadzira, kuyedza nekugadzirisa maredhiyo kwakakosha. Edza kusarudza nhepfenyuro dzakasiyana-siyana uye uve nechokwadi chekuti receiver inoshanda zvakanaka. Kugadzirisa kunogona kuitwa kune antenna neamplifier kuti uwane mhedzisiro yakanaka.
Nyaya Yekutumira Zviri Nyore
Kuti tinzwisise chinotumira mashoko chiri nyore, tichatsanangura maitiro ekutumira chiratidzo chenzwi kuburikidza ne AM radio module.
1. Kunobva Ruzha:
Shandisa chinhu chiri nyore chekutaura senge maikorofoni. Maikorofoni iyi inotora ruzha yorushandura kuita chiratidzo chemagetsi.
2. Dunhu reModulator:
Chiratidzo chinobva pamaikorofoni chinopihwa kune AM modulator. Dunhu iri rinosanganisa chiratidzo cheaudio nechiratidzo checarrier frequency chinogadzirwa ne oscillator.
3. Kusimbisa Zviratidzo:
Chiratidzo chakagadziriswa chinowedzerwa nedunhu reamplifier kuti chive nechokwadi chekuti simba rakakwana rekutumira.
4. Antena Inotumira:
Chiratidzo chakakwidziridzwa chinozotumirwa kuburikidza neantenna. Iva nechokwadi chekuti antenna inoenderana nefrequency yecarrier kuti ishande zvakanaka.
Matambudziko neMhinduro
Kuita chirongwa cheDIY radio module kunogona kukonzera matambudziko akati wandei. Heano mamwe matambudziko akajairika uye mhinduro dzawo:
1. Kupindira:
Kukanganisa kunogona kubva kunzvimbo dzakasiyana-siyana, kusanganisira zvimwe zvishandiso zvemagetsi. Kuti uzvideredze, iva nechokwadi chekuti zvikamu zvacho zvabviswa zvakanaka uye shandisa mafirita kuti ubvise masaini asingadiwe.
2. Kugadzirisa Mafambiro Enguva:
Kugadzirisa mafrequency akakodzera kunogona kuoma. Kushandisa mita yemafrequency kunogona kubatsira kuve nechokwadi chekuti kugadzirisa kwakarurama.
3. Kunzwa kweAntena:
Haasi maantenna ese akagadzirwa zvakaenzana. Kuedza magadzirirwo akasiyana eantenna nehurefu kunogona kuvandudza mashandiro ekugamuchira uye ekutumira.
4. Matambudziko eSignali yeSignali:
Kana chiratidzo chisina kusimba, funga nezvekushandisa amplifier ine simba rakawanda kana kuwedzera simba resimba rauri kushandisa.
Mhedziso
Kunzwisisa mashandiro anoita module yeredhiyo ndiyo nhanho yekutanga mukuita mapurojekiti akasiyana-siyana anonakidza eDIY. Kubva kumaredhiyo eFM akareruka kusvika kuma AM transmitters, kunzwisisa zvikamu zvekutanga uye circuitry kwakakosha. Matambudziko anosangana nawo munzira anopawo mikana yekudzidza nekukura mune zvemagetsi. Nekutsungirira uye kuyedza nguva dzose, unogona kunzwisisa nekudzidzira tekinoroji yeredhiyo yemapurojekiti ako eDIY.
