Sensor

Strap Type Tire Pressure Sensor (Transmitter)

Tsanangudzo

Isu tinofara kuunza chigadzirwa chedu mukutarisisa tireyi - iyo yekunze tyre pressure sensor yakaiswa pane vhiri remota hub. Iyi sensor inotarisisa otomatiki kudzvanywa kwetai, tembiricha uye bhatiri kuchaja kuti ive nechokwadi chekushanda kwakakwana uye kuchengetedzwa kwemugwagwa.

Iyo transmitter system ine zvinotevera zvikamu: Yemagetsi Chikamu (inosanganisira tire pressure module, crystal oscillator, antenna, RF module, yakaderera-frequency module, bhatiri) uye Architecture Chikamu (shell, tambo).

Tsanangudzo

Tire pressure pressure module: Tire pressure pressure module: Iyi yakanyatsobatanidzwa tire pressure sensor module inogara nhaka microcontroller unit (MCU), pressure sensor, uye tembiricha sensor. Nekuisa firmware muMCU, inogona kuunganidza kudzvanywa, tembiricha, uye kukwidziridza data, uye kugadzirisa uye kuvatumira kuburikidza neRF module.

Crystal oscillator: Iyo crystal oscillator inopa yekunze wachi yeMCU, uye nekugadzirisa marejista eMCU, iyo yepakati frequency uye baud rate paramita yeRF chiratidzo chinotumirwa nemupepeti inogona kutsanangurwa.

Antenna: Iyo antenna inokwanisa kufambisa data kubva kuMCU.

Radhiyo frequency module: Dhata yakatorwa kubva kune tireyi yekumanikidza module uye yakatumirwa kuburikidza ne433.92MHZFSK radio frequency.

Low frequency antenna: Iyo yakaderera-frequency antenna inopindura kune yakaderera-frequency masiginecha uye inoaendesa kuMCU.

Bhatiri: Iyo bhatiri nhanho ine mhedzisiro yakakosha pahupenyu hweiyo transmitter kana ichipa simba kuMCU.

PCB: Yakagadziriswa zvikamu uye inopa yakavimbika magetsi ekubatanidza.

Shell: Inoparadzanisa zvemukati zvemagetsi zvikamu kubva mumvura, guruva, static magetsi, nezvimwewo, uye panguva imwe chete inodzivirira zvemukati zvemukati kubva kune yakananga mechaniki maitiro.
