Ukubonisana okungenantambo – Iyunithi Elikhulu Lokulawula Lohlelo Lokubonisana Okungenantambo (UHF, Amayunithi Angama-255, Ukulandelela Ividiyo, USB/Bluetooth)
I. Incazelo Yezinhlelo
Lesisistimu singuhlelo lwezingqungquthela olungenantambo olusebenza ebhandeni le-UHF. Ilawulwa ngokuphelele ngedijithali futhi inezindlela eziningi zokukhuluma. Ingaxhunywa kumphathi wevidiyo ukuze kutholwe umsebenzi wokulandelela ividiyo. Ugesi oyisidingo seyunithi yombonisi ungasebenzisa amabhethri ajwayelekile noma amabhethri e-lithium angashajwa kabusha, okukhalayo futhi okulungele imvelo. Lesisistimu kulula ukuyisebenzisa, ayidingi ukufakwa kobunjiniyela, futhi iyasebenza ngokomnotho. Kuyisinqumo esikhethwayo sobunjiniyela bezingqungquthela.

1.1 Izici Zokusebenza
Ukudluliswa kwesignali yomsindo kufezwa nge-FM modulation. Kuhlinzeka ngokuqina okuphezulu, ubudlelwano obuphezulu phakathi kwesignali noshintsho, futhi akukho ukulibaziseka komsindo. I-capacitor microphone core eyingqayizivele yokulwa nezwi elikhulu enobuhlakani obuphezulu isetshenziswa, okwenza umsindo wekhonsathi ube almost perfect.
Zombili iziteshi zomsindo nezokulawula zidluliswa ngendlela engenazintambo, ngaphandle kwesidingo sokubeka izintambo. Indawo yokuhlanganisa isignali ingahanjiswa ngokukhululeka, okwenza ukuhlelwa kwendawo kube lula futhi kube nokuguquguquka.
Kuthuthukiswe i-algorithm ezimele yokuxhumana kwedatha kuhlelo lokubonisana, kuqinisekiswa ukuthi ngaphakathi kobubanzi besignali, isivinini sokuphendula sohlelo asithintwa inani labahambele. Abasebenzisi bangangeza noma basuse abahambele ngokuguquguquka. Umthamo ohleliwe wohlelo lwabahambele lapho uhlelo luthunyelwa efektri ungama-≤ 255 (okuhlanganisa usihlalo oyedwa).
Inemodi yokujikeleza ka-1‑2‑3‑4, izindlela zokuvinjelwa zika-1‑2‑3‑4, kanye nezindlela eziningi zokukhuluma zenkomfa ezikhethekile kumongameli. Iyunithi eyinhloko yokulawula ingaxhunywa kumphathi wevidiyo ukuze kufezekiswe umsebenzi wokulandelela ividiyo wamayunithi ezilaleli endaweni.
Ukusetshenziswa kwamandla okuphansi kakhulu, ngokukhuluma okuqhubekayo okungaphezu kwamahora angu-8 kwedivayisi kanye nesikhathi sokuphumula esingaphezu kwamahora angu-20; kungasetshenziswa ibhethri ejwayelekile ye-5th grade noma ibhethri ye-lithium yokuqala enikezwe umkhiqizi. Ibhokisi lokushaja elihambisana nalo linecircuit yokuphathwa kokushaja okuhlakaniphile, evikela kahle ibhethri, ikwandisa impilo yalo yokusebenza futhi iqinisekisa ukuphepha.
Isikrini esikhulu se-LCD. Umklamo wemenyu oyimihlahlandlela wenza ukusebenza kube lula futhi kube lula. Ubuye futhi ube nemisebenzi eminingi njengokubonisa izinga lebhethri, isexwayiso sokushoda kwamandla, isiteshi se-frequency, nokubonisa isignali.
Iyunithi eyinhloko yokulawula yakhelwe ngesakhiwo esenziwe ngensimbi yonke, ibonisa ukubukeka okukhulu nokuhloniphekile. Iyunithi esekelayo yenziwe ngopulasitiki wobunjiniyela anomklamo omusha futhi ifakwe i-antenna yangaphakathi, ibukeka kahle futhi ifanele.
