ISensom yoxinzelelo lweTire yangaphandle (iTransmitter)

Inkcazo

Inzwa yangaphandle yoxinzelelo lwesondo ifakwe kwi-hub yemoto kwaye ibeka iliso ngokuzenzekelayo uxinzelelo lwesondo, ubushushu, kunye nenqanaba lebhetri.I-sensor eyakhelwe ngaphakathi kunye ne-sensor yangaphandle ifakwe kwiindawo ezahlukeneyo, kodwa ngenxa yokuba inzwa yangaphandle ifakwe ngqo emlonyeni wegesi, ukuchaneka komlinganiselo woxinzelelo lwetayara akuyi kuchaphazeleka. Kwimilinganiselo yokushisa kwetayara, inzwa yangaphandle iya kuba nephutha le-1-2 degrees xa kuthelekiswa neyodwa eyakhelweyo.

Inzwa yoxinzelelo lwesondo yangaphandle isebenzisa i-transmitter engenazintambo ukuthumela ulwazi loxinzelelo oluvela ngaphandle kwesondo ukuya kwimodyuli ye-central receiver, kwaye emva koko ibonisa idatha yoxinzelelo lwevili ngalinye. Xa uxinzelelo lwesondo luphantsi kakhulu okanye ukuvuza komoya, inkqubo iya kwenza i-alarm ngokuzenzekelayo.Inkqubo yokuhambisa iquka la macandelo alandelayo: inxalenye ye-elektroniki (kubandakanya imodyuli yoxinzelelo lwesondo, i-crystal oscillator, i-antenna, imodyuli yeRF, imodyuli ephantsi-frequency, ibhetri) kunye nenxalenye yesakhiwo (iqokobhe, umtya).

Inkcazo

Imodyuli yoxinzelelo lweTire: Kwi-transmitter system, imodyuli yoxinzelelo lwesondo yimodyuli edityanisiweyo kakhulu ezuza ilifa le-MCU, inzwa yoxinzelelo, kunye neqondo lokushisa. Ngokufakela i-firmware kwi-MCU, uxinzelelo, ubushushu, kunye nedatha yokukhawulezisa inokuqokelelwa kwaye iqhutywe ngokufanelekileyo, kwaye ithunyelwe ngemodyuli yeRF.

I-Crystal oscillator: I-crystal oscillator inikeza iwashi yangaphandle ye-MCU, kwaye ngokucwangcisa irejista ye-MCU, iiparitha ezifana ne-frequency center kunye ne-baud ye-signal ye-RF ethunyelwe ngumthumeli inokumiselwa.

I-eriyali: I-eriyali inokuthumela idatha ekhutshwa yi-MCU.

Imodyuli yerediyo yerediyo: Idatha ithathwe kwimodyuli yoxinzelelo lwetayara kwaye yathunyelwa nge-433.92MHZFSK frequency yerediyo.

I-eriyali yefrikhwensi ephantsi: I-eriyali yefrikhwensi ephantsi inokuphendula kwiimpawu zefrikhwensi ephantsi kwaye idlulisele kwi-MCU.

Ibhetri: Inika amandla iMCU. Amandla ebhetri anempembelelo enkulu kubomi benkonzo ye-transmitter.

I-PCB: Amacandelo asisigxina kunye nokubonelela ngoqhagamshelwano oluthembekileyo lombane.

Igobolondo: Ikwahlulahlula izinto zangaphakathi zombane kumanzi, uthuli, umbane omileyo, njl.
