Inzwa Yokucindezela Kwesondo Yohlobo Lwebhande (I-Transmitter)

Incazelo

Siyajabula ukwethula umkhiqizo wethu ekuhloleni umfutho wesondo - inzwa yangaphandle yokucindezela kwesondo efakwe kuhabhu yesondo lemoto. Le nzwa igada ngokuzenzakalelayo ukucindezela kwesondo, izinga lokushisa kanye nokushajwa kwebhethri ukuze kuqinisekiswe ukusebenza kahle nokuphepha emgwaqeni.

Uhlelo lokudlulisela luqukethe lezi zingxenye ezilandelayo: Ingxenye ye-elekthronikhi (okuhlanganisa imojuli yokucindezela kwesondo, i-crystal oscillator, i-antenna, imojula ye-RF, imojuli ye-low-frequency, ibhethri) kanye Nengxenye Yezakhiwo (igobolondo, ibhande).

Imojula yokucindezela kwesondo: Imojula yokucindezela kwesondo: Lena imojula ehlanganiswe kakhulu yenzwa yokucindezela isondo ezuza njengefa iyunithi ye-microcontroller (MCU), inzwa yokucindezela, kanye nenzwa yezinga lokushisa. Ngokushumeka i-firmware ku-MCU, ingaqoqa ingcindezi, izinga lokushisa, nedatha yokusheshisa, futhi icubungule futhi iyithumele ngemojula ye-RF.

I-Crystal oscillator: I-crystal oscillator inikeza iwashi langaphandle le-MCU, futhi ngokumisa amarejista e-MCU, imvamisa yesikhungo kanye nemingcele yezinga le-baud yesiginali ye-RF ethunyelwe ngumthumeli inganqunywa.

I-antenna: I-antenna iyakwazi ukudlulisa idatha kusuka ku-MCU.

Imojula yefrikhwensi yomsakazo: Idatha ithathwe kumodule yokucindezela amathayi futhi yathunyelwa ngefrikhwensi yomsakazo engu-433.92MHZFSK.

I-antenna yefrikhwensi ephansi: I-antenna yefrikhwensi ephansi iphendula kumasiginali wefrikhwensi ephansi futhi iwadlulisela ku-MCU.

Ibhethri: Ileveli yebhethri inomthelela omkhulu kubude bempilo besithumeli uma sinikezela ngamandla ku-MCU.

I-PCB: Izingxenye ezilungisiwe futhi inikeze ukuxhumana okuthembekile kukagesi.

Igobolondo: Ihlukanisa izingxenye ze-elekthronikhi zangaphakathi emanzini, othulini, kugesi omile, njll., futhi ngesikhathi esifanayo ivimbela izingxenye zangaphakathi ekuthinteni okuqondile kwemishini.
