Gwaro rekugadzira Redhiyo neReceiver neTransmitter
Nhepfenyuro ndeimwe yenzira dzekare dzekutaurirana pasina waya dzichiri kushandiswa nanhasi. Kunyange zvazvo tekinoroji yafambira mberi nekukurumidza, nheyo huru dziri shure kweredhiyo dzinoramba dzakafanana: kushandiswa kwemafungu emagetsi kufambisa ruzivo. Mugwaro rino, tichatsanangura mavakirwo ehurongwa hweredhiyo hweDIY (Do-It-Yourself) uchishandisa receiver uye transmitter.
Pengantar
Redhiyo ine zvikamu zviviri zvikuru: receiver netransmitter. Receiver inogamuchira chiratidzo chinoburitswa netransmitter. Kana chiratidzo chagamuchirwa, receiver inochigadzirisa uye inochichinja kuita ruzha kana data rinoshanda.
Kuti tigadzire sisitimu yeredhiyo iri nyore, tinoda zvinhu zvishoma zvakakosha, zvakaita se frequency amplifier, antenna, uye signal modulation. Nekunzwisisa kwakakodzera chimwe nechimwe chezvikamu izvi, tinogona kuvaka sisitimu yeredhiyo inoshanda zvizere.
Zvinhu Zvinodiwa uye Zvishandiso
Tisati tatanga kugadzira receiver netransmitter, heino runyorwa rwezvinhu nezvishandiso zvinofanirwa kugadzirirwa:
Material:
– Crystal Oscillator: Kuona mashandiro anoita muchina unotumira neunogamuchira.
– Transistor: Kusimudzira chiratidzo.
- MaCapacitors neResistors: Zvikamu zvemagetsi zvekutanga zvekugadzirisa magetsi nemagetsi.
– Inductor (coil): Inoshandiswa kugadzira resonance yedunhu.
– Maikorofoni: Yekuisa ruzha patransmitter.
– Mutauri: Kuti ruzha rwubude parunhare.
– Antena: Kutumira nekugamuchira masaini.
– PCB (Bhodhi reDunhu Rakadhindwa): Kuunganidza zvikamu zvese nenzira yakarongeka.
Chishandiso:
– Simbi inonamira: Kunonamira zvinhu paPCB.
– Kubatanidza tambo: Kubatanidza chimwe chinhu kune chimwe.
– Multimeter: Kuyedza circuit.
– Breadboard: Yema prototypes edunhu risati rasungirirwa.
Matanho Ekugadzira
1. Gadzira Mugamuchiri
a. Kugadzira Maseketi Ekutanga
Chinogamuchira chinofanira kugadzirwa kuti chione zviratidzo zvefrequency chaiyo. Saka, uchada dhizaini yedunhu inosanganisira chinoona zviratidzo uye amplifier yeaudio. Danho rekutanga kugadzira dunhu reLC (inductor-capacitor) rinoshanda sefirita yefrequency.
b. Zvikamu Zvekunamira
1. Crystal Oscillator: Isa oscillator paPCB kuti uone frequency. Ibatanidze kune inductor kuti ugadzire resonant circuit.
2. Transistor: Shandisa transistor seamplifier kuti uwedzere chiratidzo. Solder transistor kuPCB zvichienderana nekugadzirwa kwesekitori.
3. MaCapacitors neResistors: MaCapacitors neResistors eSolder ari munzvimbo dzakakodzera kuchengetedza kugadzikana kwechiratidzo.
4. Chipika: Batanidza chipika ne amplifier output kuti unzwe ruzha rwunogamuchirwa.
c. Kuedza Dunhu
Shandisa multimeter kuti uve nechokwadi chekuti hapana mashort circuits. Kana wangoona kuti zvese zviri kushanda, vhura receiver woedza kugamuchira chiratidzo kubva kutransmitter. Gadzirisa frequency kana zvichidikanwa.
2. Kugadzira Chinotumira
a. Kugadzira Maseketi Ekutanga
Chinotumira mashoko chinofanira kukwanisa kugadzira chiratidzo pane imwe frequency uye kugadzirisa chiratidzo ichocho neruzivo (semuenzaniso, ruzha runobva kumaikorofoni).
b. Zvikamu Zvekunamira
1. Maikorofoni: Batanidza maikorofoni kuPCB iyo inoshanda senzvimbo yekuisa ruzha.
2. Crystal Oscillator: Sekunge mureceiver, oscillator inosungirirwa paPCB kuti ione frequency yekushanda.
3. Transistor: Shandisa transistor kuwedzera chiratidzo chisati chatumirwa neantenna.
4. MaCapacitors neResistors: Isa maCapacitors neResistors kuti pave nekudzora magetsi uye kugadzikana kwevoltage.
5. Antena: Batanidza antenna kune inobuda signal amplifier.
c. Kuedza Dunhu
Kana zvikamu zvese zvabatanidzwa, shandisa multimeter kuti uone kekupedzisira. Batidza transmitter uye gadzirisa frequency yayo kuti uve nechokwadi chekuti chiratidzo chiri kugamuchirwa neanogamuchira.
Kuedzwa uye Kugadziriswa
Kuti uve nechokwadi chekuti system yeredhiyo iri kushanda nemazvo, tevera matanho aya:
1. Kubatanidza Mafrequency: Iva nechokwadi chekuti mafrequency ekutumira neanogamuchira akaenzana. Kana ukagadzira zvishandiso zvese izvi wega, une simba rakazara pamusoro pemafrequency ekushanda.
2. Kureba Kwekutumira: Edza kuti chiratidzo chako chinogona kutumira kusvika papi. Kureba uku kunoenderana nesimba rekutumira uye mhando yeantenna.
3. Hunhu Hweruzha: Tarisa hunhu hweruzha kubva kunogamuchira. Ungangoda kugadzirisa zvimwe zvinhu pa amplifier circuit kuti uvandudze kubuda kweruzha.
4. Kugadzikana kweChiratidzo: Iva nechokwadi chekuti chiratidzo chakasimba uye hachikanganisike zviri nyore nemamwe mafungu.
Kuchengetedzeka uye Kutevedzera Mutemo
Pakugadzira sisitimu yeredhiyo, zvakakosha kutevedzera mitemo yemuno maererano nemafrequencies eredhiyo uye simba rekutumira. Nyika zhinji dzine mitemo yakasimba maererano nekushandiswa kwemafrequencies uye simba remasignal kudzivirira kukanganiswa kwemamwe maredhiyo.
1. Mafambiro Akabvumidzwa: Shandisa mafrequency asingakanganisi masevhisi ekutaurirana ane marezenisi kana masevhisi e emergency.
2. Simba reTransmitter: Gadzirisa simba retransmitter kuti rienderane nezvinodiwa. Kazhinji, nhepfenyuro dzeredhiyo dzevasina ruzivo dzinobvumidzwa simba rakaderera pane nhepfenyuro dzemabhizinesi.
3. Kuzviparadzanisa uye Kudzivirira: Shandisa chivharo chekudzivirira kudzivirira kusangana zvakananga nezvinhu zvemagetsi.
Mhedziso
Kuvaka sisitimu yeredhiyo ine receiver netransmitter ipurojekiti inonetsa asi inogutsa zvikuru yekuzvigadzirira. Nekunzwisisa misimboti yekutanga uye matanho akakodzera ekubatanidza, unogona kugadzira mudziyo wekutaurirana usina waya unoshanda zvizere. Yeuka kugara uchitevedzera mitemo yemuno kudzivirira kukanganiswa nemamwe masisitimu ekutaurirana uye kuchengetedza kuchengetedzeka paunenge uchishanda papurojekiti iyi yemagetsi.
