Inzwa ye-TPMS yokucindezela kwesondo eyakhelwe ngaphakathi

Incazelo

Inzwa yokucindezela kwesondo efakwe kuhabhu yemoto, igada ngokuzenzakalela umfutho wesondo, izinga lokushisa, nezinga lebhethri, kanye nomsebenzi olungisekayo, iyinzwa ehlanganisiwe ye-tpms.Umgomo wokusebenza kwesistimu yokuqapha umfutho wesondo isidlulisi sidlulisela idatha etholiwe ngaphandle kwentambo ku-CAN-BUS. ibhokisi lokwamukela, futhi ibhokisi lokugcina lokwamukela lidlulisela idatha kusistimu yokulawula emaphakathi nge-CAN BUS. Uhlelo lokudlulisela luqukethe izingxenye ezilandelayo: ingxenye ye-elekthronikhi (okuhlanganisa imojuli yokucindezela kwesondo, i-crystal oscillator, i-antenna, imojula ye-RF, ibhethri) kanye nengxenye yesakhiwo (igobolondo ne-valve).

Incazelo Yomkhiqizo

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.

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.

I-Valve: Ngokusebenzisana nama-lugs egobolondweni, isidlulisi singalungiswa ngokuthembekile ensimbi yesondo, okuyisimo esidingekayo sokwehla kwamandla emali kanye nokwehla kwamandla emali.

Imojuli yomsebenzi wenzwa ye-TPMS

Imisebenzi esemqoka ye-TPMS Sensor imi kanje:

◆Hlala ukala umfutho wesondo nezinga lokushisa, bese uqapha ukunyakaza kwesondo.

◆Ngezikhathi ezithile Dlulisa umfutho wesondo usebenzisa isignali ye-RF enephrothokholi ethile.

◆Qapha isimo sebhethri futhi wazise isistimu ngesikhathi sokudluliswa kwe-RF uma ukusebenza kwebhethri kwehla.

◆Yazisa uhlelo uma kunokuhlukahluka kokucindezela okungavamile (ukuvuza) ethayini.

◆Phendula kusignali yomyalo ye-LF evumelekile.
