Ubone amapharamitha angenantambo
Incazelo emfushane:
Kusetshenziswa umgomo wokulinganisa izinga lokushisa kwegagasi le-acoustic, ulwazi lokushisa lube izingxenye zesignali ye-electromagnetic wave frequency. Inzwa yezinga lokushisa ifakwe ngokuqondile ebusweni bezinto ezilinganisiwe zokushisa, inesibopho sokwamukela isignali yefrikhwensi yomsakazo, futhi ibuyisele isignali yomsakazo ngolwazi lokushisa kumqoqi, lapho inzwa yezinga lokushisa isebenza ngokujwayelekile, ayidingi amandla angaphandle. hlinzeka njengebhethri, i-CT loop power supply. Ukudluliselwa kwenkundla yesignali phakathi kwenzwa yokushisa kanye nomqoqi wokushisa kutholwa ngamaza kagesi angenantambo.

Omaka bomkhiqizo
I-antenna yomqoqi we-transceiver
I-antenna yokuqoqa i-transceiver idlulisa futhi ithole isignali ye-electromagnetic wave, iqedela ukutholwa kwezinga lokushisa.
Ukudluliswa kwesignali komqoqi kanye nenzwa yokushisa. Isetshenziswa kanye nomqoqi wokushisa, u-Ann C ufakwa endaweni efanayo yenzwa, enesibopho sokuxhumana ne-antenna yenzwa, uqedele ukuthumela nokwamukela isignali yokuvusa kanye nesignali yenzwa.

Inzwa Yezinga lokushisa
Inzwa yokushisa ngokuya ngendlela yokufaka, amamodeli ahlukaniswe abe: Inzwa yemfoloko yokushuna, inzwa ehlanganisiwe, inzwa yokuzikhiya yokuzikhiya yezindawo ezahlukahlukene. Ngokwezinga lokushisa nendawo yokufaka indawo, ingahlukaniswa ngohlobo olujwayelekile nohlobo lokushisa oluphezulu, oluhambisana nokutholwa kwebha yebhasi, izinga lokushisa lokuxhumana elinyakazayo. Inzwa yohlobo lokukhweza othintana naye ogudlukayo igxilile emunweni wokuxhumana we-plum blossom wokuxhumana kweselula kwekhabhinethi yenqola yesandla.

Usayizi wenzwa
I-Temperature Collector
Umqoqi wokushisa ukhiqiza isignali ye-electromagnetic wave ehambisana nemvamisa yenzwa yokushisa. Isignali yegagasi kagesi kagesi enolwazi lwezinga lokushisa olubuyiswe inzwa yezinga lokushisa iyamukelwa futhi isignali yezinga lokushisa iyahlaziywa futhi idluliselwe kudivayisi yokulawula isilinganiso sokushisa ekugcineni kwesiteshi. Umqoqi uxhumana neqembu lezinzwa ze-downlink futhi adlulisele i-RF pulse. Isignali eboniswa yizinzwa icutshungulwa emthonjeni, futhi ekugcineni ulwazi olusebenzayo lokushisa luyaxazululwa.
