Sensor sa Kantle sa Khatello ea Tyere (Transmitter)

Tlhaloso

Sensor ea khatello ea tere e ka ntle e kenngoa ka har'a koloi ea koloi 'me e shebella ka bo eona khatello ea mabili, mocheso le boemo ba betri. ho nepahala ha tekanyo ea khatello ea mabili ho ke ke ha ameha. Tekanyong ea mocheso oa thaere, sensor ea kantle e tla ba le phoso ea likhato tse 1-2 ha e bapisoa le e hahelletsoeng.

Sensor e ka ntle ea khatello ea thaere e sebelisa mochine o fetisang mohala ho romela tlhahisoleseding ea khatello ho tloha ka ntle ho thaere ho ea mojuleng oa ho amohela bohareng, ebe o bonts'a data ea khatello ea thaere ka 'ngoe. Ha khatello ea thaere e le tlase haholo kapa moea o lutla, sistimi e tla lla ka bo eona. Sistimi ea transmitter e na le likarolo tse latelang: karolo ea elektroniki (ho kenyeletsoa le mojule oa khatello ea thaere, crystal oscillator, antenna, RF module, module ea low-frequency, betri) le karolo ea sebopeho (shell, strap).

Module oa khatello ea Tyre: Ka har'a sistimi ea phetisetso, mochini oa khatello ea mabili ke mojule o kopantsoeng haholo o ruang MCU, sensor ea khatello le sensor ea mocheso. Ka ho kenya firmware ho MCU, khatello, mocheso, le data ea ho potlakisa li ka bokelloa le ho sebetsoa ka nepo, 'me tsa romelloa ka module ea RF.

Crystal oscillator: Oscillator ea kristale e fana ka oache ea kantle bakeng sa MCU, 'me ka ho hlophisa ngoliso ea MCU, liparamente tse joalo ka maqhubu a bohareng le sekhahla sa lets'oao la RF le rometsoeng ke transmitter se ka khethoa.

Antenna: Lenakana le ka romela data e fetisitsoeng ke MCU.

Mojule oa maqhubu a seea-le-moea: Lintlha li nkiloe mochining oa khatello ea mabili 'me li rometsoe ka maqhubu a seea-le-moea a 433.92MHZFSK.

Antenna e tlase ea maqhubu: Antenna e tlase e ka arabela mats'oao a maqhubu a tlase ebe ea a fetisetsa ho MCU.

Betri: E matlafatsa MCU. Matla a betri a na le tšusumetso e kholo bophelong ba tšebeletso ea transmitter.

PCB: Likarolo tse tsitsitseng le ho fana ka likhokahano tse tšepahalang tsa motlakase.

Shell: E arola likarolo tsa ka hare tsa elektroniki ho tsoa metsing, lerole, motlakase o sa fetoheng, joalo-joalo, ha e ntse e thibela ts'ebetso e tobileng ea mochini ho likarolo tsa kahare.

Likaroloana
