Sensor ya Pressure Sensor ya Type Type Type Tyre (Transmitter)

Kufotokozera

Ndife okondwa kuwonetsa malonda athu pakuwunika kuthamanga kwa matayala - sensor yakunja yakuthamanga kwa tayala yomwe imayikidwa pa gudumu lagalimoto. Sensa iyi imangoyang'anira kuthamanga kwa tayala, kutentha ndi kuchuluka kwa batri kuti zitsimikizire kuti zikuyenda bwino komanso chitetezo chamsewu.

Dongosolo la transmitter lili ndi zinthu zotsatirazi: Gawo lamagetsi (kuphatikiza gawo la kuthamanga kwa tayala, crystal oscillator, antenna, RF module, module yotsika, batire) ndi Architecture Part (chipolopolo, chingwe).

Module ya kuthamanga kwa matayala: Module ya kuthamanga kwa matayala: Iyi ndi gawo lophatikizika kwambiri la tayala lomwe limatenga gawo la microcontroller unit (MCU), sensor sensor, komanso sensor ya kutentha. Pakuyika fimuweya mu MCU, imatha kusonkhanitsa kupsinjika, kutentha, ndi kuthamangitsa deta, ndikukonza ndikuzitumiza kudzera mugawo la RF.

Crystal oscillator: The crystal oscillator imapereka wotchi yakunja kwa MCU, ndipo pokonza zolembera za MCU, ma frequency apakati ndi magawo a baud a siginecha ya RF yotumizidwa ndi transmitter amatha kudziwitsidwa.

Mlongoti: Mlongoti umatha kutumiza deta kuchokera ku MCU.

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

Mlongoti wafupipafupi: Mlongoti wocheperako umayankha kuzizindikiro zotsika ndikuzitumiza ku MCU.

Battery: Mulingo wa batri umakhudza kwambiri moyo wa transmitter popereka mphamvu ku MCU.

PCB: Zigawo zokhazikika ndikupereka maulumikizidwe odalirika amagetsi.

Chipolopolo: Imalekanitsa zida zamagetsi zamkati kuchokera kumadzi, fumbi, magetsi osasunthika, ndi zina zambiri, ndipo nthawi yomweyo imalepheretsa zida zamkati kuti zisakhudze mwachindunji.
