Indlela Izithethi Zentetho Zikawonkewonke Eziphucula Ngayo Ukusebenza Kakuhle Konxibelelwano Olungxamisekileyo

Indlela Izithethi Zentetho Zikawonkewonke Eziqinisa Ngayo Unxibelelwano Olungxamisekileyo

Kwiindawo ezinobungozi obukhulu, ukusebenza kakuhle kweziseko zonxibelelwano ezingxamisekileyo kulawula impumelelo yeenkqubo zokukhupha abantu kunye nokunciphisa iingxaki. Inkqubo yesithethi sentetho kawonkewonke isebenza njengesixhobo esiphambili sokunxibelelana ukuze kwandiswe abantu abaninzi, idlula ixesha lokubambezeleka, iimfuno zokungena, kunye nemiqobo ekhoyo kwizilumkiso zedijithali zomntu ngamnye.

Nangona izixhobo zanamhlanje zihlala zidityaniswe ne-SMS, i-imeyile, kunye neempawu zedijithali kwi-matrix yazo yokhuseleko, usasazo lwe-acoustic luhlala lusisixhobo esikhawulezileyo nesisebenzayo. Ukuyila ezi nkqubo zezicelo ezibalulekileyo zokhuseleko lobomi kufuna ukuhluka okungqongqo kwisandi esiqhelekileyo sorhwebo, ukubeka phambili ukuthembeka okungagungqiyo, ukuhanjiswa kwemiyalezo ecacileyo, kunye nokungena kwesandi okusebenzayo.

Kutheni Abacwangcisi beNgxakeko bexhomekeke kwizithethi zentetho zoluntu

Abacwangcisi beemeko zikaxakeka babeka phambiliiinkqubo zedilesi kawonkewonkekuba zibonelela ngezakhono zokusasaza ezisetyenziswa kwiindawo ezahlukeneyo ezingaxhomekekanga kwizixhobo zomsebenzisi wokugqibela. Ngokungafaniyo neenethiwekhi zeselula, ezihlala zifumana ukuxinana okukhulu kwe-bandwidth ngexesha leengxaki zasekuhlaleni ezibangela ukuba i-SMS ifike ixesha elide, isiseko sesithethi se-IP esinocingo oluqinileyo okanye esizinikeleyo siqinisekisa ukusasazwa kwemiyalezo kwangoko. Oku kukhawuleza kubaluleke kakhulu kwiimeko ezifana neziganeko zokudubula ezisebenzayo, ukuchitheka kweekhemikhali, okanye izilumkiso zemozulu embi, apho ukusinda kwabantu kuxhomekeke kulwazi lwemeko ngexesha langempela.

Ngaphezu koko, ii-acoustic arrays zanamhlanje zenzelwe ngokucacileyo ukungena kwiindawo ezinengxolo ephezulu.Imveliso yemizi-mvelisoIzakhiwo, ii-hangars zeenqwelo moya, kunye neendawo zokuthutha abantu zihlala zibhalisa amanqanaba engxolo aqhubekayo phakathi kwe-75 dB kunye ne-85 dB. Abacwangcisi beemeko ezingxamisekileyo baxhomekeke kwii-transducers ezikhethekileyo ezikhupha amandla aphezulu ezinokunqumla ngokuguquguqukayo le ngxubakaxaka ye-acoustic. Ngokusebenzisa abaqhubi boxinzelelo abaphambili kunye nee-angles ezichanekileyo zokusasazwa, ezi nkqubo ziqinisekisa ukuba imiyalelo ebalulekileyo yokufuduka ayisasazwa nje kuphela, kodwa iqondwa ngokupheleleyo ngabantu abahlala apho nokuba bakwindawo ekufutshane, ingqwalasela ebonakalayo, okanye ukungabikho konxibelelwano oluhambayo.

Indlela Izithethi Zentetho Zikawonkewonke Ezinciphisa Ngayo Ixesha Lokuphendula

Ukusasazwa kwenethiwekhi yesithethi esisasazwayo kunciphisa amaxesha okuphuma kwindawo ngokuphelisa "isigaba sokuqinisekisa" sempendulo yengqondo yomntu. Xa abahlali besiva isandi esiqhelekileyo, esingesiso esomlomo somlilo, izifundo zokuziphatha ezibonisa ukuba bahlala bechitha imizuzu ebalulekileyo befuna isiqinisekiso sesibini—bekhangela umsi, bebuza oogxa babo, okanye bejonga iifowuni zabo—ngaphambi kokuba baqalise ukufuduka ngokwasemzimbeni.

Ngokwahlukileyo koko, imiyalelo yelizwi ecacileyo esasazwa ngenkqubo yesandi sikawonke-wonke eqondakalayo iyakunciphisa kakhulu ukulibaziseka kokuthandabuza. Ngokubonelela ngemiyalelo ethile, enokusebenziseka—njengokuchonga ukuba zeziphi izitebhisi ezikhuselekileyo, ukuvakalisa ukuvalwa, okanye ukuqalisa inkqubo yokukhosela—ezi nkqubo zisusa ukungacaci kokusebenza. Imibutho elawulayo iyakuqonda oku kusebenza kakuhle; umzekelo, iNational Fire Protection Association (NFPA) iyalela ukuba unxibelelwano olungxamisekileyo lufikelele kubantu ekujoliswe kubo kwimizuzwana eli-10 emva kokuqalisa kwe-alamu. Izithethi eziqondakalayo ziqinisekisa ukuba amandla e-acoustic aguqulelwa ngokuthe ngqo kwisenzo somntu esikhawulezayo, ecinezela ixesha lokuphendula kwesiganeko ngokubanzi kwaye enciphisa iingozi zokulimala.

Yintoni Echaza Inkqubo Yesithethi Esilungele Ingxamiseko

Ukwakha inkqubo yesithethi esilungele imeko kaxakeka kufuna ukudlulela ngaphaya kwezicelo zomculo ezisisiseko zorhwebo. Ifuna ukuhlanganiswa okungqongqo kokukhulisa ukusebenza kakuhle, ii-transducers ezenziwe ngesandi, kunye nokucubungula isignali yedijithali enyamezela iimpazamo eyenzelwe ukusebenza phantsi kweemeko ezimbi.

Izinto Eziphambili Zenkqubo Yesithethi Sentetho Yoluntu

Uyilo lwenethiwekhi yesithethi seedilesi zikawonke-wonke yokhuseleko lobomi lwakhiwe phezu kwezinto ezininzi ezibalulekileyo zehardware. Embindini wezixhobo eziphambili kukho ii-amplifiers zeClass D, ezikhethwe ngokukodwa ngenxa yokusebenza kwazo kakuhle kobushushu (ezidla ngokudlula i-85%) kunye nokukwazi kwazo ukusebenza ngokuthembekileyo kumandla ebhetri yesibini ye-DC ngaphandle kokuvelisa ubushushu obuninzi kwiirakhi zezixhobo. Ezi amplifiers ziqhuba ii-transducers ngemigca ye-70V okanye ye-100V constant-voltage, i-topology yombane evumela uninzi lwezithethi ukuba zibotshelelwe ngemixokelelwane phezu kwamawaka eenyawo ze-FPLP (plenum) okanye i-FPLR (riser) cables ene-fire-rated down encinci ye-voltage.

Ukusuka kwizigaba zokukhulisa, iiDigital Signal Processors (DSPs) zilawula ukulingana, ukulibaziseka kwe-matrices, kunye noxinzelelo lwe-dynamic range. IiDSP zibalulekile ekulungiseni inkqubo kwi-acoustic signature ethile yesixhobo. Ngokusebenzisa ii-parametric equalizers ukuchonga amaza egumbi avakalayo, iDSP iqinisekisa ukuba isignali yesandi eluhlaza ilungiselelwe kakhulu ibhendi yentetho yomntu (ngesiqhelo i-300 Hz ukuya kwi-3400 Hz) ngaphambi kokuba ifikelele kwikhowuni yesithethi ebonakalayo, ngaloo ndlela iphucula ukucaca.

Ukuqonda, Ukufikelela, kunye neNqanaba loXinzelelo lweSandi

Eyona ndlela ibalaseleyo yokulinganisa isithethi sentetho esidlangalaleni kukuqondakala kwaso, okuchazwe ngokusesikweni yi-Speech Transmission Index (STI). Ngeenjongo zokukhupha ilizwi, imigangatho yokhuseleko lobomi yamazwe ngamazwe ifuna ubuncinci be-STI ye-0.50 (kwisikali esisuka ku-0 ukuya ku-1.0), ukuqinisekisa ukuba ii-syllables ezintsonkothileyo kunye nee-consonants zahlukile ngokwaneleyo ukuba abaphulaphuli baqonde imiyalelo ngaphandle komxholo. Ukufezekisa oku kufuna ulawulo oluqinileyo lobunjineli kuzo zombini iipateni zoxinzelelo lwesandi (SPL) kunye neepateni zokugubungela indawo.

Ukuze yoyise ngempumelelo ingxolo yangasemva, inkqubo kufuneka inike i-SPL ephezulu ngokuchanekileyo ukusuka kwi-10 dB ukuya kwi-15 dB kune-ambient baseline. Umzekelo, kwifektri yokuvelisa ene-80 dB ambient level eqhubekayo, izithethi zentetho kawonkewonke kufuneka zivelise ubuncinci be-95 dB endlebeni yomphulaphuli. Iinjineli ze-acoustic zidweba ngokwezibalo ii-angles ze-dispersion (ezihlala zisuka kwi-90 ukuya kwi-120 degrees) zesithethi ngasinye ukuqinisekisa ukuba iindawo zokugubungela ezigqithanayo. Le ndawo ixineneyo isusa "iindawo ezifileyo" ze-acoustic apho i-SPL inokwehla ngaphantsi komlinganiselo obalulekileyo we-+10 dB, ukuqinisekisa ukuba iyaqondakala ngokufanayo kuyo yonke iplani yomgangatho.

Kubalulekile ukuqaphela ukuba ukusebenza kakuhle konxibelelwano olungxamisekileyo akunakugwetywa kuphela ngokwemilinganiselo ye-acoustic. Ukuze kuhlangatyezwane neemfuno zokufikeleleka, ezifana nezo zigunyaziswe yi-Americans with Disabilities Act (ADA), iinkqubo zesandi kufuneka zidibene nezixhobo zesaziso ezibonakalayo (ezifana nezibane ze-strobe). Oku kuqinisekisa ukuba abantu abakwiindawo ezingevayo okanye abanengxaki yokuva, kunye nabantu abanxibe ukhuseleko lokuva kwiindawo ezinengxolo ephezulu, bafumana izilumkiso ezifanayo ezibalulekileyo.

Izithethi zeempondo ngokuchasene nezithethi ezifakwe eludongeni kunye nezifakwe eludongeni

Ukukhetha uhlobo olufanelekileyo lwe-transducer kubalulekile ekufezekiseni zombini i-SPL efunekayo kunye nokuhlanganiswa kwezakhiwo okungenamthungo. Ukhetho luhlala luwela phakathi kwezithethi zee-horn ezikhupha amandla aphezulu kunye nee-enclosures ezisasazekileyo okanye ezixhonywe eludongeni, nganye isebenzela iinjongo ezahlukeneyo ze-acoustic.

Izithethi zeempondo zisebenzisa i-compression driver edityaniswe ne-flared waveguide ukuze ziphucule i-acoustic projection kunye nokumelana nemozulu. Zihlala zithwala i-IP66 ratings, zibalulekile kwiindawo ezinkulu ezinengxolo apho i-raw volume ibaluleke kakhulu. Ngokwahlukileyo koko, izithethi ezifakwe eludongeni kunye nophahla zibonelela ngeempendulo ezibanzi ze-frequency kunye nee-engile ezibanzi, ezi-conical dispersion. Ezi mpawu zibalulekile ekugcineni i-STI ephezulu kwiindawo zangaphakathi ezijikelezayo ezinee-silingi ezisezantsi, apho ulwalathiso oluqatha lwempondo lunokubangela ukubonakaliswa kwe-acoustic okugqithisileyo.

Iimfuneko zokuThotyelwa kweMithetho, uKhuseleko, kunye nokuHlanganisa iiNkqubo

Inethiwekhi yesithethi seentetho zikawonke-wonke engxamisekileyo ayinakusebenza yodwa. Kufuneka isebenze njenge-node ehambelanayo nehambelanayo, edityaniswe kakuhle ngaphakathi kwenkqubo ebanzi yokhuseleko lobomi, ukufunyanwa komlilo, kunye nokhuseleko olubonakalayo lweziko.

Indlela Iinkqubo ZeeNtetho Zesidlangalaleni Ezixhasa Ngayo Imigangatho Yokhuseleko

Ukuthobela imithetho kulawula uyilo olusisiseko, ukusinda, kunye nokusebenza kwayo nayiphi na inkqubo yonxibelelwano lwe-alamu yelizwi engxamisekileyo (i-EVAC). EMntla Melika, ikhowudi ye-NFPA 72 imisela iikhrayitheriya ezingqongqo zokusinda, ukuvakala, kunye nokuqondakala kwenkqubo. Ngokufanayo, kwimimandla yaseYurophu, umgangatho we-EN 54-24 ulawula ukwakhiwa kunye nokusebenza kwe-acoustic kwezithethi ze-alamu yelizwi, ngelixa i-EN 54-16 igubungela izixhobo zolawulo eziphambili.

Nangona le miyalelo yokulawula ebhalwe phantsi iyalela ubuncinci bokusinda—njengokufuna iinkqubo ukuba ziqhubeke nokusebenza okuzolileyo iiyure ezingama-24 zilandelwa yimizuzu engama-30 yokusasaza i-alamu rhoqo phantsi kwamandla ebhetri yesibini—iinjineli zihlala zisebenzisa ezinye iindlela ezilungileyo zokudlula ezi ziseko. Umzekelo, izithethi ezithobelayo kufuneka zibe neendawo ezivalekileyo ezingatshiyo kwaye zixhotyiswe ngeebhloko zesiphelo se-ceramic kunye nee-fuse zobushushu. Olu yilo lwe-electromechanical luqinisekisa ukuba ukuba umlilo okwindawo ethile utshabalalisa isithethi esinye, i-fuse yobushushu iyasinqumla kwisekethe, ithintele ukufutshane okuya kukhubaza yonke indawo yesandi.

Amanqaku abalulekileyo okuHlanganisa iiAlamu zoMlilo kunye neeNkqubo zoKhuseleko

Ukusebenza kakuhle kwenkqubo yesithethi seentetho zikawonke-wonke kuxhomekeke kakhulu ekusebenzeni kwayo ngokuzenzekelayo kunye namaqonga okuchonga umlilo kunye nokhuseleko olubonakalayo. Ukuhlanganiswa kudla ngokufezekiswa kwinqanaba lehardware ngokuvalwa konxibelelwano okomileyo okanye, ngakumbi kwiinkqubo zanamhlanje, ngokusebenzisa iiprotokholi ezisekelwe kwi-IP ezifana ne-SIP (Session Initiation Protocol) kunye ne-ONVIF.

Xa iPhaneli yoLawulo lweAlarm yoMlilo (i-FACP) ibona isiganeko esikwindawo ethile—njengesixhobo sokubona umsi esibangela ukuba kubekho ingxolo okanye iswitshi yokuhamba kwamanzi—ithumela ngoko nangoko utshintsho lwemeko yengqiqo kwi-matrix yendlela yokuhambisa idilesi kawonkewonke. Ngaphakathi kwefestile engqongqo yokulibaziseka,Inkqubo ye-PAkufuneka ithule ngokuzenzekelayo umculo wangasemva ongabalulekanga kangako, itshintshe nayiphi na i-paging engeyongxamiseko, kwaye iqalise iinkqubo zokufuduka ezirekhodiweyo. Kwizicelo zokhuseleko olubonakalayo, ukuhlanganiswa ne-Video Management Systems (VMS) kuvumela abasebenzi bokhuseleko ukuba baqalise izilumkiso zesandi ezenzekelayo nezikufutshane kakhulu ngokusebenzisa izithethi ezithile zangaphandle xa kubonwa ukwaphulwa kwemingcele ngeekhamera zokujonga ezikrelekrele.

Ukuhlela iindawo, ukugqithiselwa phambili kwezinto eziphambili, amandla okugcina idatha, kunye noyilo olukhuselekileyo

Ukuqinisekisa ukusebenza okungapheliyo ngexesha lengxaki engaqhelekanga, iinkqubo zezithethi zentetho kawonkewonke zisebenzisa ubuchule bokuhlela indawo obuntsonkothileyo kunye neendlela zokwakha eziqinileyo ezikhuselekileyo. Ukuhlela indawo kuvumela abaqhubi bezokhuseleko ukuba baphume kancinci kancinci, ngokuthe nkqo kwizakhiwo eziphakamileyo—umzekelo, ukuqondisa abahlali abakwindawo yomlilo kunye nomgangatho ongaphezulu ukuba baphume kuqala, ngelixa beyalela ezinye iindawo ukuba zihlale kwindawo yazo. Iimatrices zokubeka phambili izinto ezibalulekileyo zibhalwe ngekhowudi eqinileyo ukuqinisekisa ukuba izibhengezo zemakrofoni ezibukhoma ezivela kwiziko lomyalelo womlilo zithatha indawo yazo zonke imiyalezo ezenzekelayo.

Kwinqanaba lehardware, uyilo olukhuselekileyo lokusilela lubandakanya ukuphinda-phinda kwe-amplifier ye-N+1. Ukuba i-amplifier yokuqala iyasilela ngenxa yokudinwa kwecandelo, iyunithi yokulinda ezinikeleyo ithatha ngokuzenzekelayo umthwalo wesandi kwisiqingatha sesekhondi, iqinisekisa ukuba akukho kuphazamiseka kokusasazwa. Ukongeza, i-matrix yolawulo lwenkqubo isebenzisa ukujonga ukuphela komgca (EOL) ukulinganisa ngokuqhubekayo i-100V line impedance kusetyenziswa iitoni zovavanyo ezingavakaliyo. Ukuba i-DSP ibona utshintsho olukhulu lwe-impedance—olubonisa intambo eqhekekileyo, i-short circuit, okanye i-speaker coil evuthuziweyo—ivelisa ingxelo yempazamo kwangoko kwisikhululo solawulo esiphambili, ivumela ukugcinwa kwangaphambili.

Nangona ezi zisefu zingasebenzi kakuhle, iinkqubo zentetho yoluntu azikhuselekanga kwiingxaki. Amanqaku athile okusilela, njengeentambo eziphambili eziqhekekileyo, agxininisa imfuneko yeendlela zocingo ezingafunekiyo. Ngaphezu koko, abacwangcisi bezakhiwo kufuneka baqwalasele iimeko apho izibhengezo zelizwi zinokuba yingozi, njengeemeko ezinobungozi ezisebenzayo ezinokufuna iinkqubo zokuvalelwa ngaphandle kwelizwi endaweni yokusasazwa okuvakalayo.

Indlela yokuyila nokufaka izithethi zedilesi kawonkewonke

Ukuguqulela iimfuno ze-acoustic zethiyori kwinkqubo yesithethi esisebenzayo sentetho kawonkewonke kufuna indlela ecwangcisiweyo, ekhokelwa bubunjineli yokuvavanya indawo, uyilo lwe-logical routing, kunye nokugcinwa komjikelo wobomi.

Amanyathelo Ovavanyo Lwendawo Ngaphambi Kokufakwa

Ukufakelwa ngokwasemzimbeni kwenethiwekhi yesithethi seedilesi zikawonke-wonke kufuneka kulandelwe luvavanyo olupheleleyo lwendawo ye-acoustic. Iinjineli zesandi zisebenzisa isoftware yokumodela i-acoustic eqikelelayo, efana ne-EASE (Enhanced Acoustic Simulator for Engineers), ukuze ibonise ngekhompyutha i-3D geometry yesakhiwo, ukuphakama kwesilingi, kunye nezixhobo zokwakha ezithile.

I-metric ebalulekileyo ehlalutyiweyo ngeli nqanaba lokuqikelela yi-RT60 value—ixesha elithathayo ukuba isandi sivuthe ngama-decibel angama-60. Kwiindawo ezivakala kakhulu apho i-RT60 idlula imizuzwana eyi-1.5 (ezifana neendawo zokuphumla zeglasi, amachibi okudada angaphakathi, okanye izitishi zokuhamba zekhonkrithi), ukusebenzisa izithethi zesilingi ezisemgangathweni kuya kuvelisa ii-echoes ezihambelanayo, zitshabalalise ngokupheleleyo ukuqondwa kwentetho. Kwiindawo ezinjalo ezinomsindo, uvavanyo luya kufuna ukusetyenziswa kwezithethi ezibonisa umgca eziqondakalayo kakhulu, ezilawulwa ngedijithali, okanye ngenye indlela, ukusasazwa okukhulu kwezithethi ezinamandla aphantsi ezibekwe kufutshane nomphulaphuli ukuze kwandiswe umlinganiselo wesandi esithe ngqo kwisandi esivakalayo.

Ukuhambisa imiyalezo, Izaziso ezirekhodiweyo kwangaphambili, kunye ne-Live Pageing

Nje ukuba ulwakhiwo lwe-physical transducer lumiselwe, iinjineli zimisela uyilo oluchanekileyo olulawula ukuhanjiswa kwemiyalezo, izinto ezizenzekelayo ezibangela umsindo, kunye neeparamitha ze-paging. Iinkqubo zedilesi zikawonke-wonke zanamhlanje zisebenzisa ii-routers ze-digital matrix ezikwaziyo ukuphatha iziteshi ze-audio ezingama-64 nangaphezulu ngaxeshanye kwiindawo ezininzi ezahlukeneyo zomzimba.

Ngexesha likaxakeka, inkqubo ixhomekeke kwimemori eqinileyo, engaguqukiyo ukugcina nokuqalisa izilumkiso ezirekhodiweyo kwangaphambili. Le miyalezo ezenzekelayo iqinisekisa ukuba imiyalelo ezolileyo, esemgangathweni, nehlolwe ngokusemthethweni ihanjiswa ngoko nangoko. Nangona kunjalo, inkqubo kufuneka ikwaququzelele i-dynamic live paging. Ii-paging consoles ezikwiidesika zokhuseleko, kwiindawo zokwamkela iindwendwe, okanye kwiindawo zomyalelo ezinikezelweyo zicwangciswe ngamaqhosha athile okukhetha indawo. Olu lwakhiwo luvumela abaphathi beziganeko ukuba banike imiyalelo yexesha langempela njengoko ingxaki itshintsha—njengokuthumela izihlwele kude nendlela yokuphuma evaliweyo—ngokukhawulezileyo igqitha nayiphi na iluphu erekhodiweyo edlalayo ngoku kuloo ndawo ithile.

Uvavanyo, Ukufaka Imishini, kunye noLondolozo

Isigaba sokugqibela sokusetyenziswa kwaso siquka uvavanyo oluqatha, ukuqaliswa ngokusesikweni, kunye nokusekwa kwenkqubo yokugcinwa okuqhubekayo. Ukuqaliswa kwenkqubo yesithethi sentetho kawonkewonke engxamisekileyo kufuna ukuqinisekiswa okubonakalayo kokusebenza kwe-acoustic ukuqinisekisa ukuthotyelwa kweemodeli zokuqala ze-EASE.

Iingcali zisebenzisa ii-acoustic audio analyzers ezikhethekileyo ukulinganisa i-Speech Transmission Index kunye ne-Sound Pressure Level kubude obuqhelekileyo bomphulaphuli obuziimitha ezili-1.5 ngaphezu komgangatho ogqityiweyo, zibhala iziphumo kwimephu yegridi exineneyo yesakhiwo ukuqinisekisa ukuthobela i-Authority Having Jurisdiction (AHJ). Ukugcinwa emva kokugunyaziswa, ukulungiswa kwangaphambili akunyanzelekanga; yimfuneko engqongqo yokulawula. Iiprotokholi zovavanyo zonyaka ziquka ukuqinisekisa ukuthintela kwangaphakathi kwebhetri, ukuvavanya ngokwasemzimbeni iindlela zokusilela kwee-amplifiers zokuxhasa, kunye nokuhlola ngokubonakalayo iindawo ezivalekileyo zesithethi ukuze kubonwe ukuba zonakaliswe na okanye ukungena kwamanzi, ukuqinisekisa ukuba inkqubo ihlala ikwimeko ehlala ilungile.

Indlela yokukhetha isisombululo sesithethi esifanelekileyo sentetho kawonkewonke

Abanini bezakhiwo, abakhi bezakhiwo, kunye nabalawuli be-IT bajongene nemeko enzima yokuthengwa kwempahla xa betyala imali kwiziseko zophuhliso lwesithethi sentetho kawonkewonke. Ukukhetha isisombululo esifanelekileyo kufuna ukulinganisela ukusebenza kwe-acoustic kwangoko kunye ne-topology yenethiwekhi, ukwandiswa kwexesha elide, kunye neendleko zizonke zobunini.

Iikhrayitheriya zoKhetho zokuGutyungelwa, ukuthembeka, kunye nokuKhula

Iikhrayitheriya eziphambili zokukhetha inkqubo yesithethi sentetho kawonkewonke zijikeleze ukusebenza kakuhle kokugubungela, ukuthembeka kwezixhobo, kunye nokwandiswa kwezakhiwo. Abenzi bezigqibo kufuneka bavavanye ngokungqongqo iMean Time Between Failures (MTBF) yeenxalenye eziphambili; iinkqubo ezingxamisekileyo zezinga leshishini zihlala zinezilinganiso zeMTBF ezidlula iiyure ezingama-50,000, zibonisa ii-capacitors zezinga lezoshishino kunye nolawulo oluqinileyo lobushushu.

Ukumelana nokusingqongileyo yenye into ebalulekileyo ekukhetheni. Izithethi ezibekelwe ukusetyenziswa ngaphandle, iigaraji zokupaka, okanyeiindawo zoshishino ezinzimakufuneka ibe novavanyo oluqinileyo loKhuseleko lokuNgena (IP), olufana ne-IP66, ukuqinisekisa ukusebenza nangona uchaphazeleka kwiijethi zamanzi ezinoxinzelelo oluphezulu kunye nokungena kothuli lonke. Ngaphezu koko, ukuguquguquka kuthetha ukuba i-matrix yokulawula ephakathi ekhethiweyo inokulungiselela ngaphandle kokuphazamiseka ukwandiswa kwezakhiwo kwixesha elizayo. Inkqubo efanelekileyo ivumela ukongezwa kweendawo ezintsha zokudibanisa ngokusebenzisa ilayisensi yesoftware elula okanye amakhadi e-hardware emodyuli, endaweni yokufuna ukutshintshwa kwezixhobo ze-head-end ngokupheleleyo xa kwakhiwa iphiko elitsha lesakhiwo.

Iinkqubo ezineentambo, ezisekelwe kwi-IP, ezingenazingcingo, kunye nezeHybrid

Eyona sigqibo sibalulekileyo sokwakha siquka ukukhetha phakathi kwe-analog yendabuko enentambo, inethiwekhi esekwe kwi-IP, engenazingcingo, okanye ii-topologies zothumelo lwe-hybrid.

Iinkqubo ze-analog ze-100V zemveli zihlala zingumgangatho ogqwesileyo wokuqhuba umgama omde ngamandla aphezulu apho kufuneka khona i-SPL enkulu kwiindawo ezininzi. Ngokwahlukileyo koko, izithethi ze-IP ezisebenzisa i-IP zisebenzisa iziseko ze-IT ezikhoyo, zisebenzisa i-Power over Ethernet (PoE) ukuhambisa zombini i-audio yedijithali kunye ne-DC phezu kwentambo yenethiwekhi eqhelekileyo. Nangona ziguquguquka kakhulu kwaye zinokuphathwa ngokwahlukeneyo ukuya kwisithethi esinye, iinkqubo ze-PoE+ eziqhelekileyo zazihlala zivaliwe kwi-30 watts ngeyunithi nganye. Nangona kunjalo, iinkqubo zanamhlanje ezisebenzisa umgangatho we-PoE++ (IEEE 802.3bt) zinokuxhasa i-60W ukuya kwi-90W, zandisa kakhulu ukusetyenziswa kwazo kwiindawo ezinengxolo ephezulu. Iinkqubo ze-hybrid zihlala zivala lo msantsa, zisebenzisa inethiwekhi ye-IP ye-fiber-optic ukusasaza i-audio kwikhampasi enkulu ukuya kwi-analog amplifiers ezilawula i-100V speaker loops yendawo.

Isakhelo seSigqibo sokugqibela sabaNini beZibonelelo

Kubanini beziko, isakhelo sokugqibela sesigqibo kufuneka siquke uhlalutyo olupheleleyo lweNdleko ePheleleyo yobuNini (i-TCO) oluqikelelwayo kwiminyaka eli-10 ukuya kweli-15 yokusebenza. Nangona iinkqubo ezisekelwe kwi-IP zihlala zibonisa inkcitho yokuqala yeCapital Expenditure (i-CAPEX) ephantsi kwizibonelelo esele zineziseko zenethiwekhi eziqinileyo nezingafunekiyo, abanini kufuneka baqwalasele ngononophelo iNdleko yokuSebenza (i-OPEX). Iinkqubo ezidityanisiweyo zifuna ukugcinwa kwe-IT okuqhubekayo, ukulungiswa kokhuseleko lwe-cybersecurity, uhlaziyo lwesoftware, kunye nolawulo lwe-PoE switch redundancies.

Iinkqubo ze-analog zinokufuna iindleko eziphezulu zokutsala i-trench ngaphambili, i-conduit, kunye neendleko ezizinikeleyo zekhebula, kodwa zihlala zivelisa i-OPEX ephantsi ngenxa yobulula bazo obuvaliweyo, ukungabikho kobuthathaka besoftware, kunye nobude bexesha elide behardware. Ekugqibeleni, isisombululo sesithethi sentetho kawonkewonke esifanelekileyo silungelelanisa iimfuno ezingqongqo zokhuseleko lobomi be-acoustic kunye ne-ecosystem yetekhnoloji ekhoyo yesikhungo, ukuqinisekisa ukuthembeka konxibelelwano ngokupheleleyo ngaphandle kokusebenzisa i-topology yenethiwekhi ngokungeyomfuneko.

Izinto ezibalulekileyo ekufuneka ziqwalaselwe

• Sebenzisa iziseko zesithethi ezidityaniswe nge-hardwire okanye i-IP ukuze uphephe ukuxinana kunye nokulibaziseka okunokuchaphazela izilumkiso ze-SMS okanye zeselula ngexesha likaxakeka.
• Cacisa izithethi ezikhupha amandla aphezulu kwiindawo zoshishino apho ingxolo yesiseko sendawo inokufikelela kwi-75 dB ukuya kwi-85 dB.
• Beka imiyalelo ecacileyo yelizwi phambili kuneethoni eziqhelekileyo kuba imiyalezo ethile yokuphuma, ukuvalwa kwekhaya, okanye yokukhosela endaweni inciphisa ukuthandabuza kwabahlali.
• Yila ukhuseleko lwe-PA olungxamisekileyo ukuze luhlangabezane nolindelo lwesaziso olukhawulezileyo, kubandakanya nesidingo esiqatshelwe yi-NFPA sokufikelela kubantu ekujoliswe kubo kwimizuzwana eli-10 emva kokuqaliswa kwesilumkiso.
• Khetha izixhobo ze-PA kunye ne-intercom eziqinileyo, ezimelana nemozulu, ezingangeni manzi, okanye ezimelana nokuqhuma kwiindawo zangaphandle, ezinobungozi, zaselwandle, zemigodi, zeoyile negesi, kunye nezothutho.
• Hlanganisa izithethi ze-PA kunye nee-alamu, ii-paging, ii-VoIP, ii-dispatch consoles, kunye neebhokisi zefowuni ezingxamisekileyo ukuze wenze inkqubo yonxibelelwano ezinzileyo eneendlela ezininzi.

Imibuzo ebuzwa qho

Kutheni izithethi zentetho zikawonke-wonke zibalulekile ngexesha likaxakeka?

Basasaza imiyalelo yelizwi ngoko nangoko kuye wonke umntu kwiziko ngaphandle kokuxhomekeka kwiifowuni eziphathwayo, ii-apps, okanye ukufumaneka kwenethiwekhi, benceda abantu ukuba benze ngokukhawuleza xa kukho umlilo, ukuchitheka kweekhemikhali, imozulu embi, okanye iziganeko zokhuseleko.

Izithethi ze-PA zinciphisa njani ukulibaziseka kokufuduka?

Imiyalezo ecacileyo yelizwi isusa ukungaqiniseki ngokuxelela abantu ukuba benze ntoni, baya phi, kwaye zeziphi iindlela abamele baziphephe, nto leyo enciphisa ukuthandabuza okulandela imisindo eqhelekileyo ye-alamu.

Yintoni eyenza inkqubo ye-PA yongxamiseko yahluke kwizixhobo zesandi eziqhelekileyo?

Iinkqubo ze-PA ezingxamisekileyo zibeka phambili ukuqondwa, imveliso ephezulu, ukunyamezela iimpazamo, amandla athembekileyo, kunye nokugubungela kwiindawo ezinengxolo okanye ezirhabaxa kunomgangatho womculo ongasemva.

Ngaba izithethi zentetho kawonkewonke zingasebenza kwiindawo zoshishino ezinengxolo?

Ewe. Izithethi ze-PA zemizi-mveliso zisebenzisa iziqhubi zokukhupha umoya ophezulu kunye nokusasazwa okulawulwayo ukunciphisa amanqanaba engxolo engqongileyo afumaneka rhoqo kwizityalo zokwenza imveliso, kwiindawo zothutho, nakwimigodi okanye kwizibonelelo zeoyile negesi.

Ngaba iinkqubo ze-PA eziqinileyo zifanelekile kwiindawo ezinobungozi?

Ewe. Ababoneleli abanjengoSINIWO banikezela ngemveliso yonxibelelwano ekwaziyo ukumelana nemozulu, amanzi angangeni, kunye nokuqhuma kwiindawo ezinobungozi zangaphandle nezinobungozi, kubandakanya ukumbiwa kwemigodi, ioyile negesi, ulwandle kunye neendawo zokwakha.
