Idan ka taɓa amfani da sadarwa ta RF (mitar rediyo), hanyoyin sadarwar salula, ko tsarin eriya, za ka iya cin karo da kalmar kebul na LMR. Amma menene ainihinsa kuma me yasa ake amfani da shi sosai? A cikin wannan labarin, za mu binciki menene kebul na LMR, manyan halayensa, da kuma dalilin da yasa shine zaɓin da aka fi so ga aikace-aikacen RF, sannan mu amsa tambayar 'Menene kebul na LMR?'.
Fahimci kebul na coaxial na LMR
Kebul na LMR kebul ne na coaxial wanda aka tsara don watsa siginar aiki mai ƙarfi da ƙarancin asara a aikace-aikacen RF. Ana ƙera kebul na LMR ta Times Microwave Systems kuma an san su da kyakkyawan kariya, ƙarancin asarar sigina, da juriya, wanda hakan ya sa suka dace da GPS na sadarwa mara waya、 Zaɓin da ya dace don radar da sauran tsarin RF. Ba kamar kebul na coaxial na gargajiya ba, an ƙera kebul na LMR tare da yadudduka da yawa na kayan kariya da dielectric don tabbatar da ingantaccen sigina. Suna zuwa cikin girma dabam-dabam don zaɓa daga, kamar LMR-195, LMR-240, LMR-400, da LMR-600, kowannensu an ƙera shi don buƙatun sarrafa wutar lantarki daban-daban da asarar sigina.
Babban halayen kebul na LMR coaxial
Kebulan LMR sun shahara a fannin kebul na coaxial saboda tsarinsu na musamman da fa'idodin aiki:
1. Ƙarancin asarar sigina
Ɗaya daga cikin muhimman fa'idodin kebul na LMR waɗanda ke da ƙarancin asarar sigina shine ƙarancin raguwarsu a tsawon nisa (rashin sigina). Ana samun wannan ta hanyar ingantaccen rufin dielectric da kariya, wanda ke rage asarar kuzari lokacin da sigina ke wucewa ta cikin kebul.
2. Kyakkyawan aikin kariya
Tsarin kebul na LMR yana da layukan kariya da yawa, galibi sun haɗa da kariyar zare na aluminum don kariyar EMI na farko (tsangwamar lantarki). Kariyar saƙa ta waje tana ƙara ƙarfi da kuma rage tsangwama. Wannan kariyar tana tabbatar da sigina masu ƙarfi da haske, wanda hakan ke sa kebul na LMR ya zama zaɓi mafi kyau ga aikace-aikacen RF masu laushi.
3. Dorewa da juriyar yanayi
Kamfanin Times Microwave Systems yana samar da kebul na LMR, wanda murfin waje mai ƙarfi an yi shi da polyethylene (PE) ko thermoplastic elastomer (TPE), wanda hakan ke sa shi ya yi tsayayya da hasken ultraviolet, danshi, da yanayin zafi mai tsanani. Wasu nau'ikan, kamar LMR-UF (Ultra Flex), suna ba da ƙarin sassauci ga shigarwa waɗanda ke buƙatar lanƙwasawa akai-akai da motsi.
4. Shigarwa mai sassauƙa da sauƙin amfani
Idan aka kwatanta da kebul na gargajiya mai tauri, kebul na LMR suna da sassauci mai yawa da sauƙi, wanda ke sa shigarwa ya fi sauƙi. Radius ɗin lanƙwasawansu ya fi ƙanƙanta fiye da na kebul na RF iri ɗaya, wanda ke ba da damar shigarwa mai tsauri a wurare masu rufe.
5. Dacewa da masu haɗin RF
Kebul ɗin LMR suna tallafawa masu haɗawa da yawa, gami da masu haɗin N-type (wanda aka fi amfani da shi a aikace-aikacen eriya da RF). Mai haɗin SMA (don tsarin mara waya da GPS). Mai haɗin BNC (wanda ya shahara a watsa shirye-shirye da hanyoyin sadarwa). Wannan jituwa yana sa su zama masu amfani sosai a masana'antu daban-daban.
Amfani da Kebul ɗin LMR na yau da kullun
Godiya ga kyakkyawan aikinta, ana amfani da kebul na LMR sosai a masana'antu waɗanda ke dogara da sadarwa ta RF. Wasu daga cikin aikace-aikacen da aka fi amfani da su sun haɗa da hanyoyin sadarwa mara waya da salula, tsarin eriya da RF, GPS da sadarwar tauraron ɗan adam, aikace-aikacen sararin samaniya, tsarin sa ido da tsaro.
Zaɓi kebul na LMR da ya dace
Zaɓin madaidaicin nau'in kebul na LMR ya dogara da abubuwa da yawa, gami da mita, nisa, sarrafa wutar lantarki, da yanayin muhalli. Ga wasu zaɓuɓɓuka gama gari:
LMR-195 da LMR-240: Ya dace da aikace-aikacen gajere kamar eriya ta Wi-Fi da tsarin GPS.
LMR-400: Zaɓin matsakaicin asara mai ƙarancin asara wanda aka saba amfani da shi a tsarin rediyo na wayar salula da na hanyoyi biyu.
LMR-600: Ya dace sosai don aikace-aikacen nesa inda dole ne a rage asarar sigina sosai.
Idan kana buƙatar sassaucin aikace-aikacen wayar hannu, kebul na LMR-UF (Ultra Flex) shima kyakkyawan zaɓi ne.
