Hoʻokomo ʻia ka mīkini paʻi paʻi ma ka pahu kaʻa, e nānā pono i ka puʻupuʻu kaʻa, ka mahana, a me ka pae pākaukau, a me ka hana programmable, he tpms sensor. pahu loaʻa, a hoʻouna ka pahu loaʻa hope i ka ʻikepili i ka ʻōnaehana mana kikowaena ma o CAN BUS. Aia ka ʻōnaehana transmitter i kēia mau ʻāpana: ʻāpana uila (me ka modula puʻupuʻu puʻupuʻu, ka oscillator kristal, antenna, module RF, ka pā) a me ka ʻāpana hana (shell and valve).

Hōʻike huahana

Pākuʻi paʻi pāpaʻi: I loko o ka ʻōnaehana transmitter, ʻo ka module kaomi ʻana he module i hoʻohui nui ʻia e hoʻoili i ka MCU, ka ʻike kaomi, a me ka ʻike wela. Ma ka hoʻokomo ʻana i ka firmware i loko o ka MCU, hiki ke hōʻiliʻili ʻia ka ʻikepili, ka wela, a me ka wikiwiki e like me ia, a hoʻouna ʻia ma o ka module RF.

Crystal oscillator: Hāʻawi ka oscillator kristal i kahi uaki waho no ka MCU, a ma ka hoʻonohonoho ʻana i ka papa inoa MCU, hiki ke hoʻoholo ʻia nā ʻāpana e like me ke kikowaena waena a me ka helu baud o ka hōʻailona RF i hoʻouna ʻia e ka transmitter.

Antenna: Hiki i ka antenna ke hoʻouna i ka ʻikepili i hoʻouna ʻia e ka MCU.

Lekiō uila: Ua lawe ʻia ka ʻikepili mai ka module kaomi a hoʻouna ʻia ma o ka lekiō 433.92MHZFSK.

Pākuʻi: Mana i ka MCU. He hopena nui ka mana pākaukau i ke ola lawelawe o ka transmitter.

PCB: Nā ʻāpana paʻa a hāʻawi i nā pili uila hilinaʻi.

Shell: Hoʻokaʻawale i nā ʻāpana uila i loko mai ka wai, ka lepo, ka uila static, a me nā mea ʻē aʻe, ʻoiai e pale ana i ka hopena mechanical i nā ʻāpana kūloko.

Valve: ʻO ka hui pū ʻana me nā lugs ma ka pūpū, hiki ke hilinaʻi ʻia ka transmitter ma ke kila huila, ʻo ia ke kūlana kūpono no ka piʻi ʻana o ka paʻa a me ka deflation.

TPMS Sensor hana module

ʻO nā hana nui o ka TPMS Sensor penei:

◆E ana mau i ke kaomi a me ka mahana, a e nānā i ka neʻe ʻana o ka huila.

◆E hoʻouna pinepine i ka paʻi paʻi ma ka hoʻohana ʻana i kahi hōʻailona RF me kahi protocol kikoʻī.

◆E nānā i ke kūlana o ka pākaukau a hoʻomaopopo i ka ʻōnaehana i ka wā o ka hoʻouna ʻana RF inā hoʻohaʻahaʻa ka hana ʻana o ka pākaukau.

◆E hoʻomaopopo i ka ʻōnaehana inā loaʻa nā ʻano like ʻole o ke kaomi (leak) i loko o ka huila.

◆E pane i ka hōʻailona kauoha LF kūpono.
