Indlela Izikhulumi Zenkulumo Yomphakathi Eziqinisa Ngayo Ukuxhumana Okuphuthumayo

Ezindaweni ezisengozini enkulu, ukusebenza kahle kwengqalasizinda yokuxhumana okuphuthumayo kusho impumelelo yezinqubo zokususa abantu kanye nokunciphisa izinkinga. Uhlelo lwesikhulumi senkulumo yomphakathi lusebenza njengendawo yokuxhumana eyinhloko yesaziso esikhulu, ludlula ukubambezeleka, izidingo zokungena, kanye nezithiyo ezitholakala ezixwayisweni zedijithali ngazinye.

Nakuba izikhungo zesimanje zivame ukuhlanganisa i-SMS, i-imeyili, kanye nezimpawu zedijithali ku-matrix yazo yokuphepha, ukusakaza nge-acoustic kusalokhu kuyithuluzi elisheshayo neliphumelelayo. Ukuklama lezi zinhlelo zezinhlelo zokusebenza ezibalulekile zokuphepha empilweni kudinga ukuhluka okuqinile kumsindo ojwayelekile wezentengiselwano, kubeka phambili ukuthembeka okungaguquki, ukulethwa kwemiyalezo ecacile, kanye nokungena komsindo okuphumelelayo.

Kungani Abahleli Bezimo Eziphuthumayo Bethembele Ezikhulumini Zomphakathi

Abahleli bezimo eziphuthumayo babeka phambiliizinhlelo zekheli lomphakathingoba zinikeza amakhono okusakaza asetshenziswa kabanzi anganciki kumadivayisi abasebenzisi bokugcina. Ngokungafani namanethiwekhi eselula, avame ukubhekana nokuminyana okukhulu kwe-bandwidth ngesikhathi sezinkinga zendawo okuholela ekubambezelekeni okukhulu kokulethwa kwe-SMS, ingqalasizinda yesipikha se-IP esixhunywe ngocingo noma esizinikele iqinisekisa ukusakazwa komyalezo ngokushesha. Lokhu kushesha kubalulekile ezimweni ezifana nemicimbi yokudubula esebenzayo, ukuchitheka kwamakhemikhali, noma izixwayiso zesimo sezulu esibi, lapho ukusinda komuntu kuncike ekuqaphelweni kwesimo ngesikhathi sangempela.

Ngaphezu kwalokho, ama-acoustic array anamuhla aklanywe ngokusobala ukuze angene ezindaweni ezinomsindo ophezulu.Ukukhiqiza kwezimboniIzikhungo, ama-hangar ezindiza, kanye nezindawo zokuthutha zivame ukubhalisa amazinga omsindo aqhubekayo aphakathi kuka-75 dB no-85 dB. Abahleli bezimo eziphuthumayo bathembele kuma-transducer akhethekile akhipha amandla aphezulu anganqamula ngokuguquguqukayo lokhu kuphazamiseka kwe-acoustic. Ngokusebenzisa abashayeli bokucindezela abathuthukile kanye nama-engeli okusabalala aqondile, lezi zinhlelo ziqinisekisa ukuthi iziqondiso ezibalulekile zokuphuma azisakazwa nje kuphela, kodwa ziqondwa ngokuphelele ngabantu abahlala kuzo kungakhathaliseki ukuthi zizungezile kangakanani, ukugxila okubonakalayo, noma ukuntuleka kokuxhumana kweselula.

Indlela Izikhulumi Zenkulumo Yomphakathi Ezinciphisa Ngayo Isikhathi Sokuphendula

Ukufakwa kwenethiwekhi yezikhulumi zomphakathi ezisatshalaliswayo kunciphisa izikhathi zokuphuma endaweni ngokuqeda "isigaba sokuqinisekisa" sempendulo yengqondo yabantu. Lapho abahlali bezwa ithoni evamile, engeyona eyomlomo ye-alamu yomlilo, izifundo zokuziphatha ezisekelwe emibonweni zibonisa ukuthi bavame ukuchitha imizuzu ebalulekile befuna isiqinisekiso sesibili - befuna intuthu, bebuza ozakwabo, noma behlola amafoni abo - ngaphambi kokuqala ukususwa ngokoqobo.

Ngokuphambene kakhulu, imiyalelo yezwi ecacile esakazwa ngohlelo lwezwi lomphakathi oluqondakala kakhulu inciphisa kakhulu lokhu kubambezeleka kokungabaza. Ngokunikeza iziqondiso ezithile nezisebenzayo—njengokuhlonza ukuthi yiziphi izitebhisi eziphephile, ukumemezela ukuvalwa, noma ukuqala inqubo yokukhosela endaweni—lezi zinhlelo ziqeda ukungaqondakali kokusebenza. Izinhlangano ezilawulayo ziyaqaphela lokhu kusebenza kahle; isibonelo, i-National Fire Protection Association (NFPA) iyala ukuthi ukuxhumana okuphuthumayo kumele kufinyelele kubantu abaqondiwe phakathi nemizuzwana eyi-10 yokuqala kwe-alamu. Izikhulumi eziqondakala kakhulu ziqinisekisa ukuthi amandla e-acoustic aguqulela ngqo esenzweni esisheshayo sabantu, acindezela isikhathi sokusabela kwesigameko sonke futhi anciphise izingozi zokulimala.

Yini Echaza Uhlelo Lwesikhulumi Somphakathi Olulungele Izimo Eziphuthumayo

Ukwakha uhlelo lwezipikha zomphakathi olulungele izimo eziphuthumayo kudinga ukudlulela ngale kwezinhlelo zokusebenza zomculo wangemuva wezentengiselwano eziyisisekelo. Kudinga ukuhlanganiswa okuqinile kokukhulisa ukusebenza kahle kakhulu, ama-transducer aklanywe ngendlela yomsindo, kanye nokucubungula isignali yedijithali ebekezelela amaphutha eyenzelwe ukusebenza ngaphansi kwezimo ezimbi kakhulu.

Izingxenye Eziyinhloko Zesistimu Yesikhulumi Senkulumo Yomphakathi

Ukwakheka kwenethiwekhi yezipikha zomphakathi eziphephile empilweni kwakhiwe phezu kwezingxenye eziningana zehadiwe ezibalulekile. Enhliziyweni yemishini eyinhloko kukhona ama-amplifiers e-Class D, akhethwe ngqo ngenxa yokusebenza kwawo kahle kokushisa okumangalisayo (ngokuvamile adlula u-85%) kanye nekhono lawo lokusebenza ngokuthembekile kumandla ebhethri le-DC elisekelayo lesibili ngaphandle kokukhiqiza ukushisa okweqile kuma-rack emishini. Lawa ma-amplifiers aqhuba ama-transducers ngemigqa engu-70V noma engu-100V engaguquki, i-topology kagesi evumela izipikha eziningi ukuthi ziboshwe ngezintambo ezinde phezu kwezintambo ze-FPLP (plenum) noma ze-FPLR (riser) eziyizinkulungwane zamamitha ngomlilo ngokwehla okuncane kwe-voltage.

Ukusuka ezigabeni zokukhulisa, ama-Digital Signal Processors (DSPs) aphatha ukulingana, ukubambezeleka kwe-matrices, kanye nokucindezelwa kwebanga eliguquguqukayo. Ama-DSP abalulekile ekulungiseni uhlelo ukuze luhambisane nesiginesha ethile ye-acoustic yesikhungo. Ngokusebenzisa ama-parametric equalizers ukuze kukhishwe amaza egumbi azwakalayo, i-DSP iqinisekisa ukuthi isignali yomsindo eluhlaza ilungiselelwe kakhulu ibhendi yenkulumo yomuntu (ngokuvamile kusuka ku-300 Hz kuya ku-3400 Hz) ngaphambi kokuba ifinyelele ikhoni yesipikha esingokoqobo, ngaleyo ndlela ikhulise ukucaca.

Ukuqondisisa, Ukumbozwa, kanye Nezinga Lokucindezela Komsindo

Isilinganiso esiphezulu sesistimu yezikhulumi zenkulumo yomphakathi ukuqondakala kwaso, okulinganiselwe ngokusemthethweni yi-Speech Transmission Index (STI). Ngezinjongo zokususa izwi, amazinga okuphepha kokuphila emhlabeni jikelele ngokuvamile adinga okungenani i-STI engu-0.50 (esikalini esingu-0 kuya ku-1.0), okuqinisekisa ukuthi ama-syllables ayinkimbinkimbi kanye nongwaqa kuhlukile ngokwanele ukuze izilaleli ziqonde imiyalelo ngaphandle komongo. Ukufeza lokhu kudinga ukulawulwa okuqinile kobunjiniyela kuzo zombili iZinga Lokucindezela Komsindo (SPL) kanye namaphethini okumboza indawo.

Ukuze kunqotshwe ngempumelelo umsindo wangemuva, uhlelo kumele lunikeze i-SPL ephakeme ngokunembile kusuka ku-10 dB kuya ku-15 dB kunesisekelo se-ambient. Isibonelo, esitshalweni sokukhiqiza esinomsindo we-ambient oqhubekayo ongu-80 dB, izikhulumi zekheli lomphakathi kumele zikhiqize ngokuthembekile okungenani u-95 dB endlebeni yomlaleli. Onjiniyela be-acoustic bamapha ama-engeli okusabalala (ngokuvamile angu-90 kuya ku-120 degrees) esipikha ngasinye ukuze baqinisekise ukuthi izindawo zokumboza ezihambisanayo ziyagudlana. Lesi sikhala esiqinile sisusa "izindawo ezifile" ze-acoustic lapho i-SPL ingase yehle ngaphansi komkhawulo obalulekile we-+10 dB, okuqinisekisa ukuzwakala okufanayo kulo lonke uhlelo lwephansi.

Kubalulekile ukuqaphela ukuthi ukusebenza kahle kokuxhumana okuphuthumayo akukwazi ukwahlulelwa kuphela ngama-acoustic metrics. Ukuze kuhlangatshezwane nezidingo zokufinyeleleka, njengalezo ezibekwe yi-Americans with Disabilities Act (ADA), izinhlelo zomsindo kumele zihlanganiswe nemishini yesaziso esibonakalayo (njengezibani ze-strobe). Lokhu kuqinisekisa ukuthi abantu abahlezi lapho abayizithulu noma abanenkinga yokuzwa, kanye nabantu abagqoke isivikelo sokuzwa ezindaweni ezinomsindo ophezulu, bathola izexwayiso ezifanayo ezibalulekile.

Izipikha Zezimpondo vs. Izipikha Ezifakwe Ophahleni Nezifakwe Odongeni

Ukukhetha uhlobo olufanele lwe-transducer kubalulekile ekufinyeleleni kokubili i-SPL edingekayo kanye nokuhlanganiswa kwezakhiwo okungenamthungo. Ukukhetha kuvame ukuwela phakathi kwezipikha ze-horn ezikhipha kakhulu kanye nezindawo zokuvala ezifakwe odongeni noma ezifakwe odongeni, ngayinye isebenzela izinjongo ezihlukile ze-acoustic.

Izipikha ze-Horn zisebenzisa umshayeli wokucindezela ohambisana nomhlahlandlela wamagagasi ovuthayo ukuze kwandiswe ukuvela kwe-acoustic kanye nokumelana nesimo sezulu. Ngokuvamile zinezilinganiso ze-IP66, zibalulekile ezindaweni ezinkulu nezinomsindo lapho ivolumu eluhlaza ibaluleke kakhulu khona. Ngokuphambene nalokho, izipikha zophahla nezifakwe odongeni zinikeza izimpendulo zemvamisa ebanzi kanye nama-engeli abanzi, ahlanganisiwe okusabalala. Lezi zici zibalulekile ekugcineni i-STI ephezulu ezindaweni zangaphakathi eziguquguqukayo ezinophahla oluphansi, lapho ukuqondiswa okunzima kophondo kungadala ukubonakaliswa kwe-acoustic okweqile.

Izidingo Zokuthobela Imithetho, Ukuphepha, kanye Nokuhlanganiswa Kwesistimu

Inethiwekhi yezipikha zomphakathi eziphuthumayo ayikwazi ukusebenza yodwa. Kumelwe isebenze njengenodi ehambisana ngokuqinile, ehlanganiswe kahle ngaphakathi kohlelo olubanzi lokuphepha kokuphila, ukutholwa komlilo, kanye nokuphepha ngokomzimba kwesikhungo.

Indlela Izinhlelo Zezikhulumi Zokukhuluma Zomphakathi Ezisekela Ngayo Izindinganiso Zokuphepha

Ukuthobela imithetho kulawula ukwakheka okuyisisekelo, ukusinda, kanye nokusebenza kwanoma yiluphi uhlelo lokuxhumana nge-alamu yezwi ephuthumayo (i-EVAC). ENyakatho Melika, ikhodi ye-NFPA 72 isungula izindlela eziqinile zokusinda, ukuzwakala, kanye nokuzwakala kohlelo. Ngokufanayo, ezindaweni zaseYurophu, indinganiso ye-EN 54-24 ilawula ukwakhiwa kanye nokusebenza kwe-acoustic kwezikhulumi ze-alamu yezwi, kuyilapho i-EN 54-16 ihlanganisa imishini yokulawula ephakathi.

Nakuba le mithetho yokulawula ebhalwe phansi inquma ukuthi kungakanani ukusinda—njengokudinga izinhlelo ukuthi ziqhubeke nokusebenza okuthule kwamahora angu-24 kulandelwe imizuzu engama-30 yokusakaza okuqhubekayo kwe-alamu ngaphansi kwamandla ebhethri lesibili—onjiniyela bavame ukusebenzisa imikhuba engcono kakhulu yokudlula lezi zisekelo. Isibonelo, izikhulumi ezihambisanayo kumele zibe nezindawo zokuvala ezingashi umlilo futhi zihlonyiswe ngamabhulokhi e-ceramic terminal kanye nama-fuse okushisa. Lo mklamo we-electromechanical uqinisekisa ukuthi uma umlilo wendawo ubhubhisa isikhulumi esisodwa, i-fuse yokushisa iyasihlukanisa nesifunda, ivimbele ukusondelana okungapheli okwakungakhubaza yonke indawo yomsindo.

Amaphuzu Abalulekile Okuhlanganisa Ama-alamu Omlilo Nezinhlelo Zokuphepha

Ukusebenza kahle kwesistimu yezipikha zekheli lomphakathi kuncike kakhulu ekusebenzisaneni kwayo okuzenzakalelayo namapulatifomu okuthola umlilo kanye nokuphepha ngokomzimba. Ukuhlanganiswa kuvame ukufezwa ezingeni lehadiwe ngokuvalwa kokuxhumana okomile noma, ngokuya ngokusetshenziswa kwesimanje, ngamaphrothokholi asekelwe ku-IP njenge-SIP (Session Initiation Protocol) kanye ne-ONVIF.

Uma i-Fire Alarm Control Panel (FACP) ithola umcimbi wendawo—njenge-activator smoke detector noma i-water flow switch—idlulisela ngokushesha ushintsho lwesimo se-logic ku-matrix yokuqondisa ikheli lomphakathi. Ngaphakathi kwefasitela eliqinile lokulibaziseka, i-Uhlelo lwe-PAkumele ithulise ngokuzenzakalelayo umculo wangemuva ongabalulekile kangako, isuse noma yikuphi ukubhanqa okungeyona okuphuthumayo, futhi iqalise izinqubo zokuphunyuka ezirekhodiwe ngaphambilini. Ezinhlelweni zokuphepha ngokomzimba, ukuhlanganiswa ne-Video Management Systems (VMS) kuvumela abasebenzi bezokuphepha ukuthi baqalise izixwayiso zomsindo ezizenzakalelayo, ezisendaweni ephezulu ngezipikha zangaphandle ezithile lapho kutholakala ukwephulwa kwemingcele ngamakhamera okuqapha ahlakaniphile.

Ukuhlela, Ukweqa Okubalulekile, Amandla Okusekelayo, kanye Nomklamo Ophephile

Ukuqinisekisa ukusebenza okungaphazanyiswa ngesikhathi senhlekelele ephithizelayo, izinhlelo zezikhulumi zenkulumo zomphakathi zisebenzisa indlela eyinkimbinkimbi yokubeka indawo kanye nezakhiwo eziqinile eziphephile. Ukubekela indawo kuvumela abaqhubi bezokuphepha ukuthi bakhiphe abantu abazongena ezindaweni eziphakeme ngezigaba—ngokwesibonelo, baqondise abahlali phansi komlilo kanye naphansi phezulu ngqo ukuthi baphume kuqala, ngenkathi beyalela ezinye izindawo ukuthi zihlale endaweni yazo. Ama-matrices okubeka phambili abhalwe ngekhodi eqinile ukuqinisekisa ukuthi izimemezelo zemakrofoni eziphuthumayo ezivela esikhungweni somyalo womlilo zithatha indawo yazo zonke imilayezo ezenzakalelayo.

Ezingeni lehadiwe, ukwakheka okuphepha ukwehluleka kuhilela ukuphindaphinda kwe-amplifier ye-N+1. Uma i-amplifier eyinhloko ihluleka ngenxa yokukhathala kwengxenye, iyunithi yokulinda ezinikele ithatha ngokuzenzakalelayo umthwalo womsindo ngaphakathi kwengxenye yomzuzwana, iqinisekisa ukuphazamiseka okungenalutho ekusakazeni. Ngaphezu kwalokho, i-matrix yokulawula uhlelo isebenzisa ukuqapha kokuphela komugqa (i-EOL) ukuze ilinganise njalo ukuvimba komugqa we-100V kusetshenziswa amathoni okuhlola angazwakali. Uma i-DSP ithola ukushintsha okukhulu kokuvimba—okubonisa ikhebula elinqunyiwe, i-short circuit, noma i-speaker coil evuvukile—ikhipha ngokushesha umbiko wephutha esiteshini sokulawula esikhulu, okuvumela ukulungiswa okusheshayo.

Naphezu kwalezi zisefo zokwehluleka, izinhlelo zekheli lomphakathi azivikelekile ebuthakathakeni. Amaphuzu ambalwa okwehluleka, njengezintambo ezinkulu ezinqanyuliwe, aqokomisa isidingo sezindlela zokuxhuma izintambo ezingafuneki. Ngaphezu kwalokho, abahleli bezikhungo kumele bacabangele izimo lapho izimemezelo zezwi zingaba yingozi, njengezimo ezisongelayo ezisebenzayo ezingadinga izinqubo zokuvala ngokuthula kunokusakazwa okuzwakalayo.

Indlela Yokuklama Nokufaka Izikhulumi Zekheli Lomphakathi

Ukuhumusha izidingo ze-acoustic zethiyori zibe uhlelo lwesikhulumi senkulumo yomphakathi olusebenzayo kudinga indlela ehlelekile, eholwa ubunjiniyela yokuhlola indawo, ukwakheka komzila onengqondo, kanye nokugcinwa komjikelezo wokuphila.

Izinyathelo Zokuhlola Indawo Ngaphambi Kokufaka

Ukufakwa ngokomzimba kwenethiwekhi yezipikha zekheli lomphakathi kumele kwandulelwe ukuhlolwa okuphelele kwesayithi le-acoustic. Onjiniyela bomsindo basebenzisa isofthiwe yokumodela i-acoustic ebikezelayo, njenge-EASE (Enhanced Acoustic Simulator for Engineers), ukuze badwebe nge-inthanethi i-geometry ye-3D yesikhungo, ukuphakama kophahla, kanye nezinto zokwakha ezithile.

Isilinganiso esibucayi esihlaziywe phakathi nalesi sigaba sokubikezela yinani le-RT60—isikhathi esithathayo ukuthi ukushaya komsindo kubole ngama-decibel angu-60. Ezindaweni eziphindaphindayo kakhulu lapho i-RT60 idlula khona imizuzwana eyi-1.5 (njengezindawo zokuphumula zeglasi-atrium, amachibi okubhukuda angaphakathi, noma iziteshi zokuhamba zekhonkrithi), ukusebenzisa izikhulumi zophahla ezijwayelekile eziqondisa yonke indawo kuzokhiqiza ama-echo ahambisanayo, kubhubhise ngokuphelele ukuzwakala kwenkulumo. Ezindaweni ezinjalo ezinobutha, ukuhlolwa kuzodinga ukusetshenziswa kwezikhulumi eziqondisa kakhulu, eziqondisa ngedijithali, noma ngenye indlela, ukusatshalaliswa okukhulu kwezikhulumi ezinamandla aphansi ezibekwe eduze kwesilaleli ukuze kwandiswe isilinganiso somsindo oqondile nomsindo ophindaphindayo.

Ukuhambisa Imilayezo, Izexwayiso Eziqoshwe Kusenesikhathi, kanye Nokubuka Amakhasi Okubukhoma

Uma ukwakheka kwe-transducer ebonakalayo sekumisiwe, onjiniyela balungiselela ukwakheka okunengqondo okulawula ukuhanjiswa kwemiyalezo, iziqalisi ezenzakalelayo, kanye namapharamitha e-paging. Izinhlelo zekheli lomphakathi zanamuhla zisebenzisa ama-router e-digital matrix akwazi ukuphatha iziteshi zomsindo ezingu-64 noma ngaphezulu ngesikhathi esisodwa kuzo zonke izindawo ezihlukene zomzimba.

Ngesikhathi esiphuthumayo, uhlelo luthembele kwimemori yesimo esiqinile, engashintshi ukugcina nokuqalisa izexwayiso eziqoshiwe kusengaphambili. Le miyalezo ezenzakalelayo iqinisekisa ukuthi imiyalelo ezolile, ehlelekile, nehlolwe ngokomthetho ithunyelwa ngokushesha. Kodwa-ke, uhlelo kumele futhi lusize i-paging ebukhoma enamandla. Ama-paging consoles atholakala kumadeski okuphepha, ezindaweni zokwamukela izivakashi, noma ezikhungweni zomyalo ezinikezelwe ahlelwe ngezinkinobho ezithile zokukhetha indawo. Lo mklamo uvumela abaphathi bezigameko ukuthi banikeze imiyalelo yesikhathi sangempela njengoba inkinga ishintsha—njengokuqondisa izixuku kude nokuphuma okuvinjiwe—ngokushesha badlule noma yikuphi ukujikijela okuqoshiwe okudlalwayo njengamanje kuleyo ndawo ethile.

Ukuhlola, Ukufaka Imishini, kanye Nokulungisa

Isigaba sokugcina sokusetshenziswa sihilela ukuhlolwa okuqinile, ukuqaliswa ngokusemthethweni, kanye nokusungulwa kwenqubo yokulungisa eqhubekayo. Ukuqaliswa kohlelo lwezikhulumi zomphakathi oluphuthumayo kudinga ukuqinisekiswa okungokomthetho kokusebenza kwe-acoustic ukuqinisekisa ukuhambisana namamodeli okuqala e-EASE.

Ochwepheshe basebenzisa abahlaziyi bomsindo abakhethekile be-acoustic ukuze balinganise i-Speech Transmission Index kanye ne-Sound Pressure Level ekuphakameni okujwayelekile kwabalaleli okungamamitha angu-1.5 ngaphezu kwephansi eliqediwe, bebhala phansi imiphumela kumephu yegridi ebanzi yesikhungo ukuze bafakazele ukuthobela i-Authority Having Jurisdiction (AHJ). Ukulungiswa ngemuva kokugunyazwa, okusebenzayo akuyona into yokuzikhethela; kuyimfuneko eqinile yokulawula. Izinqubo zokuhlola zaminyaka yonke zifaka phakathi ukuqinisekisa ukungasebenzi kahle kwebhethri, ukuhlola ngokomzimba izindlela zokwehluleka kwama-amplifiers okusekelayo, kanye nokuhlola ngokubonakalayo izindawo zokuvala izipikha ukuze kutholakale ukuthi azinawo yini umonakalo emvelweni noma ukungena kwamanzi, ukuqinisekisa ukuthi uhlelo luhlala lusesimweni sokulungela njalo.

Indlela Yokukhetha Isixazululo Esifanele Sesikhulumi Senkulumo Yomphakathi

Abanikazi bezikhungo, abaklami bezakhiwo, kanye nabaqondisi be-IT babhekene nesimo sokuthengwa esiyinkimbinkimbi lapho betshala imali engqalasizinda yezikhulumi zesikhulumi somphakathi. Ukukhetha ikhambi elifanele kudinga ukulinganisela ukusebenza kwe-acoustic okusheshayo ne-topology yenethiwekhi, ukusabalala kwesikhathi eside, kanye nezindleko eziphelele zobunikazi.

Izindlela Zokukhetha Zokumbozwa, Ukuthembeka, kanye Nokukhula

Izindlela eziyinhloko zokukhetha uhlelo lwesikhulumi senkulumo yomphakathi zigxile ekusebenzeni kahle kokumbozwa, ukuthembeka kwehadiwe, kanye nokukhula kwezakhiwo. Abenzi bezinqumo kumele bahlole ngokucophelela i-Mean Time Between Failures (MTBF) yezingxenye eziyinhloko; izinhlelo eziphuthumayo zezinga lebhizinisi ngokuvamile zinezilinganiso ze-MTBF ezidlula amahora angu-50,000, ezibonisa ama-capacitor ezinga lezimboni kanye nokuphathwa okuqinile kokushisa.

Ukuqina kwemvelo kungenye into ebalulekile yokukhetha. Izikhulumi ezibekelwe ukusetshenziswa ngaphandle, emagaraji okupaka, nomaizindawo zezimboni ezinzimakumele ibe nezilinganiso eziqinile zokuvikela ukungena (i-IP), njenge-IP66, ukuqinisekisa ukusebenza naphezu kokuchayeka kumajethi amanzi anomfutho ophezulu kanye nokungena kothuli okuphelele. Ngaphezu kwalokho, ukukhuliswa kusho ukuthi i-matrix yokulawula ephakathi ekhethiwe ingahambisana kalula nokwandiswa kwesikhungo esizayo. Uhlelo olufanele luvumela ukwengezwa kwezindawo ezintsha zokufaka ama-paging ngokusebenzisa amalayisense esofthiwe alula noma amakhadi ehadiwe e-modular, kunokudinga ukushintshwa okuphelele kwe-forklift yemishini ye-head-end lapho kwakhiwa iphiko elisha lesakhiwo.

Izinhlelo Ezinezintambo, Ezisekelwe ku-IP, Ezingenantambo, kanye Nezihlanganisiwe

Isinqumo esibaluleke kakhulu sokwakha sihilela ukukhetha phakathi kwezindlela zokudlulisa ezisebenzisa izintambo zendabuko, ezisebenzisa i-IP, ezingenantambo, noma ezisebenzisa i-hybrid.

Izinhlelo ze-analog zendabuko ze-100V zihlala ziyindinganiso yegolide yokugijima okunamandla aphezulu, ibanga elide lapho kudingeka khona i-SPL enkulu kuzo zonke izikhungo ezinkulu. Ngakolunye uhlangothi, izikhulumi zekheli zomphakathi ezisekelwe ku-IP zisebenzisa ingqalasizinda ye-IT ekhona, zisebenzisa i-Power over Ethernet (PoE) ukuletha kokubili umsindo wedijithali kanye namandla e-DC phezu kwekhebula elilodwa lenethiwekhi ejwayelekile. Nakuba ziguquguquka kakhulu futhi zikwazi ukukhulunywa ngazinye kuze kufike kusipika esisodwa, izinhlelo ze-PoE+ ezijwayelekile zazivame ukuvalwa ngama-watts angu-30 ngeyunithi ngayinye. Kodwa-ke, izinhlelo zesimanje ezisebenzisa izinga le-PoE++ (IEEE 802.3bt) zingasekela i-60W kuya ku-90W, zandisa kakhulu ukusetshenziswa kwazo ezindaweni ezinomsindo ophezulu. Izinhlelo ze-hybrid zivame ukuvala leli gebe, zisebenzisa inethiwekhi ye-IP ye-fiber-optic ukusabalalisa umsindo kuyo yonke ikhampasi enkulu kuma-amplifier e-analog ahlukaniswe ngokwezigaba aqhuba izipikha ze-100V zendawo.

Uhlaka Lwesinqumo Sokugcina Lwabanikazi Bezikhungo

Kubanikazi bezikhungo, uhlaka lwesinqumo sokugcina kumele luhlanganise ukuhlaziywa okuphelele kwe-Total Cost of Ownership (TCO) okulindelwe esikhathini sokuphila kokusebenza seminyaka eyi-10 kuya kweyi-15. Ngenkathi izinhlelo ezisekelwe ku-IP zivame ukuveza i-Capital Expenditure (CAPEX) yokuqala ephansi ezindaweni esezivele zinengqalasizinda yenethiwekhi eqinile, engasasebenzi, abanikazi kumele bacabangele ngokucophelela i-Operational Expenditure (OPEX). Izinhlelo ezinethiwekhi zidinga ukulungiswa okuqhubekayo kwe-IT, ukulungiswa kwezokuphepha kwe-cyber, izibuyekezo zesofthiwe, kanye nokuphathwa kokwehliswa kwe-PoE switch.

Izinhlelo ze-analog zingadinga izindleko eziphezulu zokufaka imisele kusengaphambili, i-conduit, kanye nezindleko zokufaka izintambo ezizinikele, kodwa zivame ukukhiqiza i-OPEX ephansi ngenxa yobulula bazo obuvaliwe, ukuntuleka kobuthakathaka besofthiwe, kanye nokuphila isikhathi eside kwehadiwe. Ekugcineni, ikhambi lesipikha somphakathi elifanele livumelanisa izidingo eziqinile zokuphepha kwempilo ye-acoustic nesistimu yobuchwepheshe ekhona yesikhungo, ukuqinisekisa ukuthembeka okuphelele kokuxhumana ngaphandle kokwenza i-topology yenethiwekhi ngokweqile ngokungadingekile.

Izinto Ezibalulekile Okufanele Uzicabangele

• Sebenzisa ingqalasizinda yezipikha zomphakathi ezixhunywe ngocingo noma ze-IP ukuze ugweme ukuminyana nokubambezeleka okungathinta izaziso ze-SMS noma zeselula ngesikhathi sezimo eziphuthumayo.
• Cacisa izipikha ezikhipha umsindo ophezulu ezindaweni zezimboni lapho umsindo ojwayelekile ungafinyelela ku-75 dB kuya ku-85 dB.
• Beka imiyalelo yezwi ecacile kuqala kunemisindo ejwayelekile ngoba imiyalezo ethile yokuthutha, ukuvalwa, noma yokukhosela endaweni inciphisa ukungabaza kwabahlali.
• Yakha ukumbozwa kwe-PA ephuthumayo ukuze kuhlangatshezwane nokulindelwe kwesaziso okusheshayo, okuhlanganisa nesidingo esiqashelwa yi-NFPA sokufinyelela abantu abaqondiwe phakathi nemizuzwana eyi-10 yokuqaliswa kwe-alamu.
• Khetha imishini ye-PA kanye ne-intercom eqinile, engangenisi simo sezulu, engangeni manzi, noma engaqhumi ezindaweni zangaphandle, eziyingozi, zasemanzini, zezimayini, zikawoyela negesi, kanye nezokuthutha.
• Hlanganisa izikhulumi ze-PA nama-alamu, ama-paging, i-VoIP, ama-dispatch consoles, kanye namabhokisi ocingo oluphuthumayo ukuze udale uhlelo lokuxhumana oluqinile oluneziteshi eziningi.

imibuzo ejwayelekile ukubuzwa

Kungani izikhulumi zenkulumo zomphakathi zibalulekile ngezikhathi eziphuthumayo?

Basakaza imiyalelo yezwi esheshayo kuwo wonke umuntu endaweni ngaphandle kokuthembela kumafoni eselula, izinhlelo zokusebenza, noma ukutholakala kwenethiwekhi, okusiza abantu ukuthi bathathe isinyathelo ngokushesha ngesikhathi somlilo, ukuchitheka kwamakhemikhali, isimo sezulu esibi, noma izehlakalo zokuphepha.

Izikhulumi ze-PA zikunciphisa kanjani ukubambezeleka kokuphuma kwabantu?

Imiyalezo yezwi ecacile isusa ukungaqiniseki ngokutshela abagibeli ukuthi benzeni, ukuthi baye kuphi, nokuthi yiziphi izindlela okufanele bazigweme, okunciphisa ukungabaza okuvame ukulandela amathoni ajwayelekile e-alamu.

Yini eyenza uhlelo lwe-PA oluphuthumayo luhluke kumishini yomsindo ejwayelekile?

Izinhlelo ze-Emergency PA zibeka phambili ukuzwakala, umkhiqizo ophezulu, ukubekezelela amaphutha, amandla athembekile, kanye nokumbozwa ezindaweni ezinomsindo noma ezinzima kunekhwalithi yomculo wangemuva.

Ingabe izikhulumi zenkulumo zomphakathi zingasebenza ezindaweni zezimboni ezinomsindo?

Yebo. Izikhulumi ze-PA zezimboni zisebenzisa izishayeli zokukhipha okuphezulu kanye nokuhlakazeka okulawulwayo ukuze kuncishiswe amazinga omsindo ozungezile avame ukutholakala ezitshalweni zokukhiqiza, ezindaweni zokuthutha, kanye nasezimayini noma ezindaweni zikawoyela negesi.

Ingabe izinhlelo ze-PA eziqinile zifanelekile ezindaweni eziyingozi?

Yebo. Abahlinzeki abanjengo-SINIWO bahlinzeka ngemikhiqizo yokuxhumana engangenisi manzi, engangeni manzi, kanye nengaqhumi ezindaweni ezingaphandle neziyingozi, okuhlanganisa izimayini, uwoyela negesi, izindawo zasolwandle kanye nezindawo zokwakha.
