Isivamvo

Uhlobo lomtya kwiSensom yoxinzelelo lweTire (iTransmitter)

Inkcazo

Siyavuya ukwazisa imveliso yethu ekujongweni koxinzelelo lwetayara - isivamvo soxinzelelo sangaphandle esifakwe kwihabhu yevili lemoto. Le sensor ngokuzenzekelayo ibeka esweni uxinzelelo lwetayara, ubushushu kunye nentlawulo yebhetri ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko ezindleleni.

Inkqubo yokuhambisa iqulethe izinto ezilandelayo: Inxalenye ye-Electronic (kubandakanywa imodyuli yoxinzelelo lwesondo, i-crystal oscillator, i-antenna, imodyuli ye-RF, imodyuli ephantsi-frequency, ibhetri) kunye neCandelo loKwakha (igobolondo, i-strap).

Inkcazo

Imodyuli yoxinzelelo lweTire: Imodyuli yoxinzelelo lweTire: Le yimodyuli edibeneyo yoxinzelelo lwesondo edibeneyo efumana i-microcontroller unit (MCU), inzwa yoxinzelelo, kunye neqondo lokushisa. Ngokufakela i-firmware kwi-MCU, inokuqokelela uxinzelelo, ubushushu, kunye nedatha yokukhawulezisa, kwaye iqhubeke kwaye ithumele ngemodyuli yeRF.

I-Crystal oscillator: I-crystal oscillator ibonelela ngewotshi yangaphandle ye-MCU, kwaye ngokuqwalasela iirejista ze-MCU, i-frequency center frequency and baud rate parameters ye-RF signal ethunyelwe yi-transmitter inokumiselwa.

I-eriyali: I-eriyali iyakwazi ukuthumela idatha esuka kwi-MCU.

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

I-eriyali yefrikhwensi ephantsi: I-eriyali ye-low-frequency iphendula kwiimpawu ze-low-frequency kwaye idlulisele kwi-MCU.

Ibhetri: Inqanaba lebhetri linempembelelo ebalulekileyo kubomi bomthumeli xa unikezela amandla kwi-MCU.

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

Igobolondo: Ikwahlulahlula izinto zangaphakathi zombane kumanzi, uthuli, umbane ongatshintshiyo, njl.njl., kwaye kwangaxeshanye inqanda izinto zangaphakathi kwimpembelelo ethe ngqo yomatshini.
