Yekunze Tire Pressure Sensor (Transmitter)

Tsanangudzo

External tire pressure sensor inoiswa mumotokari yemotokari uye inotarisa otomatiki kudzvanywa kwetayi, tembiricha, uye bhatiri level.Iyo yakavakirwa-mukati sensor uye yekunze sensor inoiswa munzvimbo dzakasiyana, asi nekuda kwekuti sensor yekunze inoiswa zvakananga pamuromo wegesi, kurongeka kweyero yekumanikidza matai hakuzokanganisike. Muchiyero chekushisa kwevhiri, sensor yekunze ichava nekukanganisa kwe 1-2 madhigirii kana ichienzaniswa neyakavakirwa-mukati.

Iyo yekunze tire yekumanikidza sensor inoshandisa isina waya inotumira kutumira ruzivo rwekumanikidza kubva kunze kwevhiri kuenda kune yepakati inogamuchira module, uye yobva yaratidza iyo yekumanikidza data yevhiri rega rega. Kana simba retai ranyanya kuderera kana mhepo inodonha, sisitimu inongoerekana yarira.Iyo transmitter system ine zvikamu zvinotevera: chikamu chemagetsi (kusanganisira tyre pressure module, crystal oscillator, antenna, RF module, low-frequency module, bhatiri) uye chikamu chechimiro (shell, strap).

Tsanangudzo

Tire pressure yemodule: Mune transmitter system, iyo tire yekumanikidza module imodhi yakanyatsobatanidzwa inogara nhaka yeMCU, pressure sensor, uye tembiricha sensor. Nekuisa firmware muMCU, kudzvanywa, tembiricha, uye kukwidziridza data inogona kuunganidzwa uye kugadziriswa zvinoenderana, uye kutumirwa kuburikidza neRF module.

Crystal oscillator: Iyo crystal oscillator inopa yekunze wachi yeMCU, uye nekugadzirisa iyo MCU rejista, ma paramita akadai sepakati frequency uye baud mwero weRF chiratidzo chinotumirwa nemupepeti anogona kutariswa.

Antenna: Iyo antenna inogona kutumira data inofambiswa neMCU.

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

Yakaderera frequency antenna: Yakaderera frequency antenna inogona kupindura kune yakaderera frequency masaini uye nekuaendesa kuMCU.

Bhatiri: Inopa simba iyo MCU. Simba rebhatiri rine simba guru pahupenyu hwebasa remupepeti.

PCB: Yakagadziriswa zvikamu uye inopa yakavimbika magetsi ekubatanidza.

Shell: Inoparadzanisa zvemukati zvemagetsi zvikamu kubva mumvura, guruva, static magetsi, nezvimwewo, ukuwo ichidzivirira yakananga mamejini kukanganisa kwezvinhu zvemukati.
