I-Multi-connection Bluetooth Module Ngokuthuthuka kwesayensi nobuchwepheshe, umphakathi wabantu usuphokophele enkathini ehlakaniphe kakhulu nexhumene. Kuleli zwe elishintshashintsha njalo, ubuchwepheshe bezokuxhumana obungenawaya sebubaluleke kakhulu kunangaphambili. Ukuhlangabezana nesidingo esikhulayo sokuxhumana, siyaziqhenya ngokwethula umkhiqizo omusha nothuthukisiwe, i-BT826F Bluetooth […]

I-Preface Bluetooth ubuchwepheshe bokuxhumana obungenawaya ebangeni elifushane, obungadluliswa ngenethiwekhi yokuxhumana yamabanga amafushane. I-Bluetooth iphinde isetshenziselwe ukuthola omakhalekhukhwini kanye namadivayisi womuntu siqu wedijithali (PDA). I-Bluetooth ingasetshenziswa ukuthuthukisa izinhlelo zokusebenza ezihlukahlukene ezifana nokuma kwezokuphepha kanye nokuma kwekhaya okuhlakaniphile. Ubuchwepheshe bokumisa i-Bluetooth 1. Ukuma okuzenzakalelayo: Ngokufaka

Indawo yokupaka iyindawo ebalulekile Ezikhungweni Zamabhizinisi, izitolo ezinkulu, izibhedlela ezinkulu, amapaki ezimboni, izikhungo zemibukiso, njll. Ungayithola kanjani ngokushesha indawo yokupaka engenalutho nokuthi ungayithola kanjani ngokushesha nangokunembile indawo yezimoto zabo sekuyikhanda lezimoto eziningi. abanikazi.Ngakolunye uhlangothi, izikhungo eziningi zeBhizinisi ezinkulu zinezindawo zokupaka eziyindlala

I-RTLS isifinyezo se-Real Time Location Systems. I-RTLS iyindlela ye-radiolocation esekwe kusignali engase isebenze noma ingenzi lutho. Phakathi kwazo, okusebenzayo kuhlukaniswe nge-AOA (i-Angle yokufika) kanye ne-TDOA (indawo yokuhluka kwesikhathi sokufika), i-TOA(isikhathi sokufika), i-TW-TOF(isikhathi sendiza yezindlela ezimbili), i-NFER(i-near-field electromagnetic range) nokunye. ku. Ukukhuluma ngokubeka, wonke umuntu uzoqala acabange

1. I-Bluetooth module Imbobo ye-serial I-serial interface ifushaniswa njengembobo ye-serial, eyaziwa nangokuthi i-serial communication interface, ngokuvamile eyaziwa nangokuthi imbobo ye-COM. Leli yitemu elivamile, futhi izixhumanisi ezisebenzisa ukuxhumana kwe-serial zibizwa ngokuthi ama-serial port. Imbobo ye-serial iyi-hardware interface. UART isifinyezo esithi

Njengamanje, imakethe yesiteshi sokushaja emakethe yaseShayina isesesigabeni sokuthuthukiswa. Ukuhlomula ekwenyukeni kokwamukelwa kwemakethe kagesi omsulwa, ukwenyuka koxhaso oluqhutshwa yinqubomgomo, kanye nokuzimisela okukhulayo kwabaqhubi bezimoto ukutshala imali, isidingo nokuhlinzekwa kwesiteshi sokushaja ezimakethe ezinkulu zaseShayina kulindeleke ukuthi kukhule kakhulu.

Ukuma kwe-Bluetooth okunembe okuphezulu ngokuvamile kubhekisela emithanjeni engaphansi noma ngisho nokunemba kokuma kwezinga lesentimitha. Leli zinga lokunemba lihluke kakhulu ekunembeni kwamamitha angu-5-10 okunikezwa ubuchwepheshe obujwayelekile bokumisa. Isibonelo, lapho usesha isitolo esithile esikhungweni sezitolo, ukunemba kokuma okungamasentimitha angama-20 noma ngaphansi kungasiza kakhulu ekutholeni
