Dzidziso yekugadzira redhiyo isina waya
Tekinoroji yekutaurirana iri kuramba ichikura nekukurumidza, imwe yacho iredhiyo. Kunyange zvazvo makumi emakore apfuura, taiziva maredhiyo semidziyo yakakura ine tambo dzinoperekedza, ikozvino tava kugona kugadzira maredhiyo asina waya. Maredhiyo asina waya anoshanda zvakanyanya, anoda tambo shoma, uye ari nyore kutakura chero kupi. Chinyorwa chino chichakutungamira munzira dzekugadzira redhiyo isina waya.
Nhanganyaya yeRadio Isina Waya
Redhiyo isina waya mudziyo unokwanisa kugamuchira nhepfenyuro dzeredhiyo pasina chikonzero chekuti tambo chaiyo ibatanidzwe kune antenna kana sosi yemagetsi. Izvi zvinobvumira vashandisi kunakidzwa nemimhanzi, nhau, nerumwe ruzivo zviri nyore. Iyi tekinoroji inowanzo shandisa mafungu emagetsi kutumira masaini kubva kune chinotumira kuenda kune chinogamuchira redhiyo.
Hwaro hwedzidziso hwekugadzirwa kweredhiyo isina waya hunosanganisira zvinhu zvakati wandei: chinotumira, chinogamuchira, uye masaisai eredhiyo. Chinotumira chinogadzira masaisai eredhiyo, ayo anozotumirwa nemhepo. Chinogamuchira, kune rumwe rutivi, chinotora nekushandura masaisai aya eredhiyo kuita ruzha.
Zvishandiso Nezvinhu Zvinodiwa
Usati watanga kugadzira redhiyo isina waya, gadzirira maturusi nezvinhu zvinotevera:
– Bhodhi redunhu (Bhodhi rechingwa)
- Transistor yeNPN (semuenzaniso, transistor yemhando ye2N2222)
– MaCapacitor (hunhu hwacho hunotangira pa10pF kusvika pa1000uF, zvichienderana nekugadzirwa)
– Resistor (hunhu hunotangira pa10 Ohm kusvika 1 MOhm, zvichienderana nekugadzirwa)
– INDUCTOR (hunhu hunotangira pa10uH kusvika 1mH, zvichienderana nezvinodiwa)
– Waya yekubatanidza (waya yejumper)
– Bhatiri (kazhinji 9V)
– Crystal oscillator (semuenzaniso 10.7 MHz)
– Mamwe maIC (Integrated Circuits) akadai seTDA7000 kana MK484 evanogamuchira redhiyo yeAM/FM
Uyezve, heano maturusi aunogona kuda:
- Solder netini
- Multimeter
– Mapurini madiki ekucheka
- Antena yekombiki kana waya refu seantena
Matanho Ekugadzira
1. Kugadzira Dunhu reTransmitter
Tisati tagadzira redhiyo receiver, tinofanira kugadzira chinotumira mashoko chiri nyore. Izvi zvinogona kuitwa tichishandisa transistor se signal amplifier. Heano matanho:
– Gadzira Oscillator: Oscillator ndiyo inogadzira frequency inofanira kutumirwa. Unogona kushandisa 10.7 MHz crystal oscillator sepakati pe oscillator. Batanidza crystal pin nechigadziko che transistor kuburikidza ne capacitor diki (10pF-100pF).
– Chinosimudzira Masaini: Batanidza chinounganidza masaini emagetsi (+9V) kuburikidza ne inductor (coil) inosvika 10uH-100uH. Kuti uve nechokwadi chekuti chiratidzo chakasimba zvakakwana, wedzera ma capacitor nema resistors sezvinodiwa kuti circuit ienderane.
– Batanidza Antena: Batanidza antena kune chinoburitsa tambo che transistor. Antena inogona kunge iri waya yakareba kana antena yakakosha yakagadzirirwa frequency yeredhiyo yawakasarudza.
2. Kugadzira Chinogamuchidza Chiratidzo
Kana transmitter yagadzirira, tichatarisa pa redhiyo receiver. Tichashandisa IC receiver seTDA7000 kana MK484, iyo yakagadzirirwa kugamuchira masaini eredhiyo.
– Gadzirira Receiver Module: Isa radio receiver IC pabhodhi rekugadzira. Mirayiridzo iri mudatasheet reIC ichakutungamirira pakubatanidza mapini akakodzera kune zvimwe zvikamu.
– Antena kuCircuit Connection: Batanidza antenna inogamuchira (yakasiyana neantenna inotumira) kupin yekupinda yeantenna iri paIC.
– Kugadzirisa Mafambiro: Batanidza capacitor inochinja kana kuti varactor diode kuti ugadzirise mapindiro ekugamuchira. Izvi zvinokutendera kuti uchinje nhepfenyuro yeredhiyo yaunoda kuteerera.
– Chinosimudzira Ruzha: Kuti ruzha rwunzwike, batanidzai chinobuda cheIC kune chidiki chinosimudzira ruzha. Unogona kushandisa IC yakaita seLM386 kuti uwedzere ruzha kuitira kuti rwunzwike kuburikidza nespika diki.
3. Kuedzwa kweRedhiyo
Kana zvese zvabatanidzwa, danho rinotevera nderekuyedza. Batidza transmitter yako nekuibatanidza nebhatiri, uye ita zvimwe chete nereceiver. Isa frequency yereceiver kuti ienderane nefrequency yetransmitter. Kana zvese zvakanaka, receiver yako inofanira kukwanisa kutora chiratidzo uye kuchishandura kuita ruzha kuburikidza nespeaker.
– Kugadziriswa kweKutenderera uye Kutenderera: Ungangoda kugadzirisa zvimwe zvinhu pa transmitter oscillator kuti uve nechokwadi chekuti chiratidzo chinoburitswa chakasimba uye chinoenderana nefrequency yekugamuchira.
– Kuongorora Zvikamu: Kana mugamuchiri asinganzwi chiratidzo, tarisazve zvikamu nezvinobatanidza zviri pabhodhi rechingwa, iva nechokwadi chekuti hapana chakadzoserwa shure kana kuti chakasununguka.
4. Bhokisi reKunatsiridza uye reDunhu
Kana zvabudirira, danho rekupedzisira nderekuvandudza nekusimbisa circuit yako nekuiisa mubhokisi rinoyevedza uye rakagadzikana. Unogona kushandisa bhokisi repurasitiki kana rehuni, woisa makiyi ekugadzirisa frequency, volume, uye switch yekudzima/kudzima.
- Dhizaini yeAntenna Yakanakisisa: Unogona kuyedza kureba uye rudzi rweantenna kuti uwane kugamuchira kwakanakisa.
– Magadzirirwo emagetsi: Kana uchishandisa mabhatiri, iva nechokwadi chekuti ari nyore kutsiva kana kuchajazve. Neimwe nzira, unogona kufunga nezvekushandisa power bank kana zvichidikanwa.
Mhedziso
Kuvaka redhiyo isina waya kunoda ruzivo rwekutanga rwemagetsi uye hunyanzvi hwemaoko kuti ugadzire zvikamu. Nezvishandiso zvakakodzera nezvinhu, pamwe chete negwara rakajeka, unogona kugadzira redhiyo yako isina waya.
Hazvizongogumiri pakugutsikana chete, asi zvichawedzerawo kunzwisisa kwako mashandiro anoita kutaurirana neredhiyo nemagetsi. Ndinovimba kuti chidzidzo ichi chinokubatsira kuvaka redhiyo isina waya inoshanda uye inoshanda! Rombo rakanaka!
