Kupanikizika kwa matayala opangidwa ndi TPMS sensor

Kufotokozera

Sensor yothamanga ya matayala yomwe imayikidwa pagalimoto yamagalimoto, imayang'anitsitsa kuthamanga kwa tayala, kutentha, ndi mlingo wa batri, ndi ntchito yosinthika, ndi integrated tpms sensor. bokosi lolandira, ndipo bokosi lomaliza lolandira limatumiza deta ku dongosolo lapakati lolamulira kudzera mu CAN BUS. Dongosolo la transmitter lili ndi magawo otsatirawa: gawo lamagetsi (kuphatikiza gawo la kuthamanga kwa tayala, crystal oscillator, antenna, RF module, batri) ndi gawo lachipolopolo (chipolopolo ndi valavu).

Module ya kuthamanga kwa matayala: Mu transmitter system, gawo la kuthamanga kwa tayala ndi gawo lophatikizika kwambiri lomwe limalandira MCU, sensor sensor, komanso sensor ya kutentha. Pakuyika fimuweya mu MCU, kupanikizika, kutentha, ndi kuthamangitsa deta zitha kusonkhanitsidwa ndikukonzedwa moyenera, ndikutumizidwa kudzera mugawo la RF.

Crystal oscillator: The crystal oscillator imapereka wotchi yakunja kwa MCU, ndipo pakukonzekera kaundula wa MCU, magawo monga ma frequency apakati ndi kuchuluka kwa baud kwa siginecha ya RF yotumizidwa ndi transmitter imatha kudziwitsidwa.

Mlongoti: Mlongoti ukhoza kutumiza deta yofalitsidwa ndi MCU.

Ma frequency module: Deta idatengedwa kuchokera ku gawo la kuthamanga kwa tayala ndikutumizidwa kudzera pa 433.92MHZFSK pafupipafupi.

Battery: Imalimbitsa MCU. Mphamvu ya batri imakhudza kwambiri moyo wautumiki wa transmitter.

PCB: Zigawo zokhazikika ndikupereka maulumikizidwe odalirika amagetsi.

Chipolopolo: Imapatula zida zamagetsi zamkati kuchokera kumadzi, fumbi, magetsi osasunthika, ndi zina zambiri, ndikuletsanso kukhudzidwa kwachindunji ndi zida zamkati.

Vavu: Kugwirizana ndi zipolopolo pa chipolopolo, chotumiziracho chimatha kukhazikika pazitsulo zamagudumu, zomwe ndizofunikira pakutsika kwa matayala ndi kutsika kwamphamvu.

TPMS Sensor function module

Ntchito zazikulu za TPMS Sensor ndi izi:

◆ Nthawi zonse muziyezera kuthamanga kwa tayala ndi kutentha kwake, ndipo muzionetsetsa mmene tayala likuyendera.

◆ Nthawi ndi nthawi tumizani kuthamanga kwa tayala pogwiritsa ntchito chizindikiro cha RF chokhala ndi ndondomeko inayake.

◆Yang'anirani momwe batire ilili ndikudziwitsani makinawo panthawi yotumizira RF ngati batire ikuwonongeka.

◆ Dziwitsani dongosolo ngati pali kusinthasintha kwachilendo (kuthamanga) mu tayala.

◆ Yankhani chizindikiro chovomerezeka cha LF.
