Cadaadiska taayirka ee lagu dhex dhisay TPMS

Sharaxaada

Dareemka cadaadiska taayirka ee lagu rakibay xudunta gaariga, si toos ah ula socota cadaadiska taayirka, heerkulka, iyo heerka batteriga, iyo shaqada barnaamijka, waa dareemaha tpms isku dhafan. Nidaamka la socodka cadaadiska taayirada mabda'a shaqada waa gudbiyaha si wireless ah u gudbiya xogta la ogaaday CAN-BUS sanduuqa helitaanka, iyo sanduuqa helista ugu dambeeya wuxuu u gudbiyaa xogta nidaamka xakamaynta dhexe iyada oo loo marayo BASKA CAN. Nidaamka gudbiyaha wuxuu ka kooban yahay qaybaha soo socda: qayb elektaroonik ah (oo ay ku jiraan moduleka cadaadiska taayirka, oscillator crystal, anteeno, module RF, batari) iyo qayb dhismeed (qafoof iyo valve) .Waa dareeraha cadaadiska taayirka caalamiga ah ee baabuurta.

Sharaxaada Alaabta

Cutubka cadaadiska taayirka: Nidaamka gudbiyaha, moduleka cadaadiska taayirku waa cutub aad isku dhafan oo dhaxla MCU, dareenka cadaadiska, iyo dareenka heerkulka. Marka la geliyo firmware-ka MCU-ga, cadaadiska, heerkulka, iyo xogta dardargelinta ayaa la ururin karaa oo loo farsamayn karaa si waafaqsan, waxaana loo diri karaa moduleka RF.

Crystal oscillator: oscillator-ka crystal wuxuu bixiyaa saacad dibadda ah MCU, iyo marka la habeeyo diiwaanka MCU, cabbirada sida inta jeer ee xarunta iyo heerka baud ee calaamadda RF ee uu soo diro gudbiyaha ayaa la go'aamin karaa.

Anteenada: Anteenadu waxay soo diri kartaa xogta uu gudbiyo MCU.

Module soo noqnoqda raadiyaha: Xogta waxaa laga soo qaatay qaybta cadaadiska taayirka waxaana loo soo diray inta jeer ee raadiyaha 433.92MHZFSK.

Battery: Wuxuu awoodaa MCU. Awoodda batteriga ayaa saameyn weyn ku leh nolosha adeegga gudbiyaha.

PCB: Qaybaha go'an oo bixiya isku xirka korantada ee la isku halayn karo.

Shell: Waxay ka soocdaa qaybaha elektiroonigga ah ee gudaha biyaha, boodhka, korantada taagan, iwm, iyada oo sidoo kale ka hortagaysa saameynta farsamada tooska ah ee qaybaha gudaha.

Valve: La shaqaynta lugaha qolofka, gudbiyaha waxaa lagu kalsoonaan karaa in lagu hagaajiyo birta giraangiraha, taas oo ah xaalad lagama maarmaan u ah sicir bararka taayirka iyo sicir-bararka.

TPMS module function Sensor

Hawlaha ugu muhiimsan ee TPMS Sensor waa sida soo socota:

◆Si joogto ah u cabbir cadaadiska iyo heerkulka taayirka, oo la soco dhaqdhaqaaqa taayirka.

◆Si joogto ah u gudbi cadaadiska taayirka adigoo isticmaalaya calaamadda RF oo leh borotokool gaar ah.

◆La soco xaalada batteriga oo ogeysii nidaamka inta lagu guda jiro gudbinta RF haddii waxqabadka batteriga hoos u dhaco.

◆ Ogeysii nidaamka haddii ay jiraan cadaadis aan caadi ahayn oo kala duwanaansho ah (daadin) ee taayirka.

◆Ka jawaab calaamada amarka LF sax ah.
