Emhlabeni osheshayo wokuxhumana kwedijithali, ama-DMR repeaters adlala indima ebalulekile ekuqinisekiseni ukudluliswa kwezwi nokudluliswa kwedatha okucacile nokwethembekile ezindaweni ezibanzi. I-DMR repeater, noma i-Digital Mobile Radio repeater, ikhulisa ukuhlinzekwa kokuxhumana kwe-radio ngokwamukela amasignali bese ewaphinda ethululela amandla aphezulu noma ama-frequency ahlukene. Le teknoloji isibe ibalulekile kumabhizinisi, izinsizakalo eziphuthumayo, kanye nabathandi abafuna izixazululo zokuxhumana ezisebenzayo nezikhulayo. Le ndatshana ibheka izisekelo ze-DMR repeater protocols nama-frequency, ichaza ukuthi lezi zinhlelo zisebenza kanjani, futhi ihlola izindlela zokwenza ngcono ukusebenza kwazo ukuze kuthuthukiswe ukuxhumana. Ngaphezu kwalokho, sikhombisa iminikelo ye-Quanzhou Jintong Optoelectronic Technology Co., Ltd ekusekeleni ubuchwepheshe obuphambili be-DMR repeater.

Digital Mobile Radio (DMR) iyisikhungo esivulekile se-digital radio esichazwe yi-European Telecommunications Standards Institute (ETSI). Iklanyelwe ukuhlinzeka abasebenzisi ngekhwalithi yokukhuluma ethuthukisiwe, impilo yebhethri eyandisiwe, kanye nokusebenza kahle kwe-spectrum uma kuqhathaniswa nezinhlelo ze-radio ezivamile. Enhliziyweni yokuxhumana kwe-DMR kukhona uhlelo lwe-repeater, olusebenza ukuqinisa nokudlulisa amasignali, ngaleyo ndlela kwandiswe ukuhlinzeka nokuthuthukisa ukujula kwamasignali ezindaweni ezinzima noma ezindaweni zasemadolobheni.

I-DMR repeaters isebenza ngokwamukela izimpawu zedijithali ezingenayo bese ziqhubeka zidlulisa lezi zimpawu kwelinye i-frequency noma isiteshi, ngempumelelo ibhidliza izikhala zokuxhumana phakathi kwabathengi be-radio. Lezi zimpawu zisekela izici ezifana nokuhlukaniswa kwesikhathi sokufinyelela okuphindwe kabili (TDMA), okuvumela izingcingo ezimbili ezihambisanayo kwi-frequency eyodwa, kanye namakhono okudlulisa idatha yokuthumela imiyalezo ye-text kanye nezinsizakalo zokuthola indawo ye-GPS.

Ukuqonda izingxenye nokusebenza kwesistimu ye-DMR repeater kubalulekile kumabhizinisi afuna ukufaka amanethiwekhi okuxhumana aqinile. Izingxenye ezibalulekile zifaka phakathi i-base station transceiver, duplexer, antenna system, kanye ne-controller software. Ndawonye, ziqinisekisa ukuxhumana okungaphazamiseki futhi zenza kube lula ukuklama inethiwekhi enokwandiswa.

Ngemibhalo ethakazelisayo yokuhlola imishini ye-DMR ethuthukisiwe, i-Quanzhou Jintong Optoelectronic Technology Co., Ltd inikeza uhla lwezinto ezisemqoka ze-elekthronikhi ezisezingeni eliphezulu nezixazululo ezingahlanganiswa nezinhlelo ze-DMR repeater. Ubuchwepheshe babo be-optoelectronics bukhulisa ukucubungula izimpawu nokwethembeka, kubenza babe umlingani oqinile ekuthuthukiseni izinsiza zokuxhumana. Funda kabanzi ngalezi zinsizakalo zabo ku-Imikhiqizoikhasi.

I-DMR standard ihlukaniswe ngezinga ezintathu, ngayinye ichaza amandla athile nezicelo zeziphinda. Ukuqonda lezi zinga kubalulekile ekukhetheni i-DMR repeater protocol efanele ukuhlangabezana nezidingo zokusebenza.

I-Tier I ihloselwe ukusetshenziswa okungenamvume, okuphansi amandla, ngokuvamile ezinhlelweni zabathengi nezokuhweba ezifana neziteshi zomsakazo ezisebenza ngaphakathi kwemingcele ethile. Lezi zinhlelo zilula, zinikeza ukuxhumana kwezwi okuyisisekelo ngaphandle kokwesekwa kokuphindaphinda.

Ukukhetha i-DMR repeater protocol efanele kuncike osayizi benethiwekhi yokuxhumana, izici ezidingekayo, kanye nezinto ezithinta umthetho. Amabhizinisi kufanele ahlaziye lezi zinto ukuze athuthukise ukusebenza kwenethiwekhi nokusebenza kahle kwezindleko.

I-DMR repeaters isebenza kumabha frequency athile anikezwe yiziphathimandla zendawo zokuxhumana, ngokuvamile ngaphakathi kwe-VHF (136-174 MHz) kanye ne-UHF (400-470 MHz) ranges. Ukukhetha kahle i-frequency nokuhlela iziteshi kubalulekile ukuze kugwenywe ukuphazamiseka futhi kukhuliswe ukusebenza kahle kwenethiwekhi.

Ihlelo lezikhephe lichaza ukuthi kanjani ama-frequency ahlukaniswa futhi aphathwa ngaphakathi kohlelo lwe-DMR. Lihlanganisa izicabangela zezikhephe ze-simplex ne-duplex, izikhala zexesha, namakhowudi wombala asiza ukuhlukanisa phakathi kwezigaba zokukhuluma ezahlukene kanye nabasebenzisi. Ukuhlela kahle izikhephe kuqinisekisa ukuxhumana okungaphazamiseki futhi kunciphisa ingozi yokuhlangana kwezimpawu noma ukugcwala.

Ezindaweni zokuhweba nezimboni, ukuhlela kahle kwe-frequency nokulandela imithetho yendawo kuyadingeka. Ukusebenzisa uhlelo lweziteshi olwakhiwe kahle kuthuthukisa ukusebenza kahle kwazo zonke izinhlelo ze-DMR repeater futhi kusekela izimo zokusebenzisa eziningi.

Quanzhou Jintong Optoelectronic Technology Co., Ltd isebenzisa ubuchwepheshe obuphambili bokuphathwa kwe-frequency ekwakhiweni kwemikhiqizo yayo ukuze kuqinisekiswe ukuhleleka kwesignali okuhle kakhulu nokuphazamiseka okuncane. Izixazululo zabo zifaka isandla ekwakheni amandla okuphindaphinda kwe-DMR. Vakashela kuMayelana Nathiikhasi ukuze uthole ukuqonda okwengeziwe ngamandla abo obuchwepheshe.

Ukusetha uhlelo lwe-DMR repeater kudinga ubuchwepheshe bokuhlela kahle izingxenye ze-hardware ne-software. Izinyathelo ezibalulekile zifaka phakathi ukuhlela ama-frequency, ukusetha izikhawu zexesha, ukuhlela amakhodi wombala, nokuxhumanisa ama-repeater ukuze kwakhiwe inethiwekhi. Ukuhlela kahle kuqinisekisa ukusetshenziswa kahle kwemigudu futhi kunciphisa ukuphazamiseka kokuxhumana.

Abasebenzi kumele bacabangele nezici zemvelo ezifana nokubekwa kwe-antena, ukuzinza kokuhlinzekwa kwamandla, kanye nokuphepha kwenethiwekhi. Ukusebenzisa imishini yekhwalithi enesekelo esiqinile se-firmware kungasiza ekwenzeni kube lula ukugcinwa nokuxazulula izinkinga.

Amarepeater amaningi e-DMR eza nesofthiwe yokuhlela elula yokusebenzisa evumela abaphathi ukuthi benze ngezifiso izilungiselelo ngokuya ngezidingo ezithile zokusebenza. Ukuvuselelwa njalo kwe-firmware kanye nezibuyekezo zohlelo kuyas recommended ukuze kugcinwe ukusebenza okuphezulu nokuhambisana nezokuphepha.

Ukuthuthukisa ukuhlinzekwa nokusebenza kwe-DMR repeaters kuhilela amasu amaningi, kuhlanganise nokusetshenziswa kwama-antennas aphezulu, ama-repeaters anamandla aphezulu, kanye nezindlela zokuxhuma inethiwekhi. Ukuhlolwa kwezindawo nezifundo zokuhanjiswa kusiza ekutholeni izindawo ezinhle zama-repeaters ukuze kuncishiswe izindawo ezingenasignali futhi kuthuthukiswe ukungena kwesignali.

Izici ezithuthukisiwe ezifana nokwabiwa kweziteshi ezishintshashintshayo, izivumelwano zokulungisa amaphutha, kanye nokufihla kwedijithali kuthuthukisa ukwethembeka nokuphepha kokuxhumana. Ukusebenzisa lezi zinto kuqinisekisa ukuthunyelwa okungaphazamiseki nokufihlekile, okuyinto ebalulekile ezinhlelweni ezibalulekile emsebenzini.

Ukuhlanganisa ama-DMR repeaters nezinye izinhlelo zokuxhumana ezifana ne-LTE noma amanethiwekhi e-satellite kungandisa kakhulu ukuhlinzekwa futhi kulethe ukwehliswa. Ukuqeqeshwa kwababheki kanye nokuhlolwa njalo kwesistimu kusiza ekugcineni impilo yenethiwekhi nokwaneliseka komsebenzisi.

泉州市金通光电技术有限公司 (Quanzhou Jintong Optoelectronic Technology Co., Ltd) ibonakala ngezinto zayo ezintsha ze-optoelectronic ezithuthukisa ukucubungula izimpawu futhi zehlise isikhathi sokulinda ezinhlelweni zokuxhumana. Ubuchwepheshe bawo busekelwa ukusebenza kahle kwe-DMR repeater, okwenza kube umngane okhethiweyo kumabhizinisi adinga izixazululo zokuxhumana ezisezingeni eliphezulu. Hlola okwengeziwe ku-Izindabaikhasi lezibuyekezo zakamuva.

I-technology ye-DMR repeater iyisisekelo sokuxhumana kwedijithali yanamuhla, inikeza ukudluliswa kwezwi nedatha okwandekayo, okusebenza kahle, nokusebenza kahle. Ukuqonda izigaba ezahlukene ze-DMR protocols, ukuhlela kahle imvamisa neziteshi, kanye nokumiswa kahle kwezobuchwepheshe kubalulekile ukuze kuthuthukiswe ukusebenza kwenethiwekhi. Ukuthuthukiswa kokufinyelela nokusebenza kahle kuncike ekufakweni okuhlelekile nasekusebenziseni ubuchwepheshe obuphambili.

Quanzhou Jintong Optoelectronic Technology Co., Ltd ibonisa ubuchwepheshe obusha kanye nekhwalithi emkhakheni wezobuchwepheshe bokuxhumana, ihlinzeka ngemikhiqizo nezixazululo ezisekela izinhlelo eziphakeme ze-DMR repeater. Kubantu besebenzisa izinkampani ezihlose ukwakha noma ukuthuthukisa izakhiwo zabo zokuxhumana, ukubambisana nezinkampani ezihamba phambili ezifana ne泉州市金通光电技术有限公司 kuqinisekisa ukufinyelela ezinzuzweni zokuncintisana nokwesekwa kochwepheshe.

Ukuze ufunde kabanzi ngama-solutions namasevisi abo aphelele, vakashela iIkhaya ikhasi futhi uhlole ukuthi bangasiza kanjani ibhizinisi lakho ukufinyelela amakhono okuxhumana athuthukisiwe.
