Inzwa Yokucindezela Kwesondo Yangaphandle (I-Transmitter)

Incazelo

Inzwa yangaphandle yokucindezela isondo ifakwe kuhabhu yemoto futhi igada ngokuzenzakalelayo ukucindezela kwesondo, izinga lokushisa, nezinga lebhethri.Inzwa eyakhelwe ngaphakathi kanye nenzwa yangaphandle kufakwa ezindaweni ezihlukene, kodwa ngenxa yokuthi inzwa yangaphandle ifakwe ngokuqondile emlonyeni wegesi, ukunemba kwesilinganiso somfutho wesondo ngeke kuthinteke. Esilinganisweni sokushisa kwesondo, inzwa yangaphandle izoba nephutha lika-1-2 degrees uma iqhathaniswa neyakhelwe ngaphakathi.

Inzwa yangaphandle yokucindezela isondo isebenzisa isidluliseli esingenantambo ukuthumela ulwazi lwengcindezi kusuka ngaphandle kwesondo kuya kumojula yokwamukela okuphakathi, bese ikhombisa idatha yokucindezela kwesondo ngalinye. Uma umfutho wesondo uphansi kakhulu noma umoya uvuza, isistimu izokhala ngokuzenzakalelayo.Isistimu yokudlulisa imiyalezo iqukethe izingxenye ezilandelayo: ingxenye ye-elekthronikhi (kuhlanganise nemojula yokucindezela kwesondo, i-crystal oscillator, i-antenna, imojuli ye-RF, imojuli ye-low-frequency, ibhethri) kanye nengxenye yesakhiwo (igobolondo, ibhande).

Imojula yokucindezela isondo: Kuhlelo lokudlulisela, imojula yokucindezela isondo iyimojula edidiyelwe kakhulu ezuza njengefa i-MCU, inzwa yokucindezela, kanye nenzwa yokushisa. Ngokushumeka i-firmware ku-MCU, ingcindezi, izinga lokushisa, kanye nedatha yokusheshisa ingaqoqwa futhi icutshungulwe ngokufanele, futhi ithunyelwe ngemojula ye-RF.

I-Crystal oscillator: I-crystal oscillator inikeza iwashi langaphandle le-MCU, futhi ngokumisa irejista ye-MCU, imingcele efana nemvamisa yesikhungo kanye nesilinganiso se-baud yesiginali ye-RF ethunyelwe ngumthumeli inganqunywa.

Uthi: I-antenna ingathumela idatha edluliswa yi-MCU.

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

I-antenna yefrikhwensi ephansi: I-antenna yefrikhwensi ephansi ingaphendula kumasiginali aphansi futhi iwadlulisele ku-MCU.

Ibhethri: Inika amandla i-MCU. Amandla ebhethri anomthelela omkhulu empilweni yesevisi yesithumeli.

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

Igobolondo: Ihlukanisa izingxenye ze-elekthronikhi zangaphakathi emanzini, othulini, kugesi omile, njll., kuyilapho iphinde ivimbele umthelela oqondile wemishini ezintweni zangaphakathi.
