Uburyo bw'ingenzi bwo gukoresha abavuga rikijyana mu nganda mu nganda no mu bubiko

Impamvu abavuga rikijyana mu nganda ari ingenzi mu nganda

Inganda zigaragaza bimwe mu bintu bigoye cyane mu isi yubatswe muri iki gihe. Hagati y'urusaku ruhoraho rw'imashini ziremereye, urusaku rw'ibikoresho byo gufata ibikoresho, n'ahantu hanini kandi hanini ho gukorera ibikoresho, gutanga itumanaho ryumvikana neza ni akazi katoroshye cyane k'ubuhanga. Muri ibi bihe, ibikoresho bisanzwe by'amajwi by'ubucuruzi birananirwa vuba cyangwa ntibigire icyo bikora na gato. Indangururamajwi y'inganda ikorerwa mu buryo bwihariye kugira ngo itsinde izi mbogamizi z'amajwi n'ibidukikije, igenzura ko ubutumwa bw'ingenzi buca urusaku.

Gushyira mu bikorwa ibikoresho byihariyesisitemu za PA z'ingandasi ikibazo cyo koroshya ibintu gusa; ni ikintu cy'ingenzi gisabwa kugira ngo ikigo gikomeze kugira umutekano n'imikorere myiza. Iyo urusaku rwo mu kirere ruhindagurika hagati ya 85 dB na 115 dB, itumanaho ry'amajwi ridafite ubufasha ntirishoboka, kandi indangururamajwi zisanzwe zongerera urusaku mu bidukikije. Gusobanukirwa itandukaniro riri hagati y'ibikoresho by'amajwi byo mu rwego rw'ubucuruzi n'ibikoresho by'amajwi byubatswe mu nganda ni intambwe ya mbere mu gushushanya umuyoboro w'itumanaho wizewe.

Ni iki gisobanura umuvugizi w'inganda mu by'ubucuruzi

Mu by’ingenzi, indangururamajwi zo mu nganda zigaragazwa n’ubushobozi bwazo bwo kubaho n’ubushobozi bwazo bwo gutanga amajwi. Bitandukanye n’indangururamajwi z’ubucuruzi zagenewe amaduka cyangwa ibiro bigenzurwa n’ikirere, inganda zubatswe kugira ngo zihangane n’ibintu bibangamira ibidukikije cyane. Ibi birimo ibizingo byakozwe mu buryo bwa ABS bugira ingaruka zikomeye, fiberglass idakira UV, cyangwa icyuma kidashonga cyo mu mazi. Ibi bikoresho birinda kwangirika bitewe n’ibintu bya shimi, uduce duto two mu kirere, no guhindagurika kw’ibintu.

Imbere, ibice bigize iyi porogaramu bifite umwihariko. Ibyuma by'amajwi n'ibice by'amajwi byubatswe mu byuma bya phenolic resins cyangwa titaniyumu aho kuba impapuro cyangwa pulasitiki isanzwe, bigatuma bitwara neza mu buryo buhoraho kandi butanga imbaraga nyinshi zidashira. Byongeye kandi, indangururamajwi za PA zo mu nganda zagenewe gukora ku rugero rw'ubushyuhe bukabije, akenshi zihabwa agaciro ko gukora kuva kuri -40°C kugeza kuri +60°C (-40°F kugeza kuri 140°F). Bakoresha kandi transformateurs zihariye ku mirongo y'amajwi ya 70V cyangwa 100V, bigatuma insinga zishobora kugera ku nsinga ibihumbi n'ibihumbi mu kigo cy'inganda zidatakaza ibimenyetso bikomeye.

Aho abavuga kuri PA batanga agaciro k'imikorere

Akamaro k'imikorere ya sisitemu y'indashyikirwa ya PA ntikagarukira kure cyane ku gushakisha amajwi gusa. Mu nganda zigezweho no mu bikoresho, izi sisitemu zikora nk'uburyo bwo kumva bw'imikorere ya sisitemu zo kugenzura zikoresha ikoranabuhanga. Mu guhuza na sisitemu zo kugenzura no kubona amakuru (SCADA) cyangwa sisitemu zo gutunganya ibikoresho (MES), imiyoboro ya PA ishobora gutangaza amakuru yikora iyo habayeho imbogamizi mu gukora, bigabanyiriza cyane igihe cyo gusana (MTTR) binyuze mu kumenyesha abakozi nyabo bakenewe ako kanya.

Byongeye kandi, agaciro kayo gafite agaciro gakomeye mu kugabanya ibyago no kugabanya inshingano. Itumanaho risobanutse neza mu gihe cy’impanuka ririnda ubwoba kandi rigategura uburyo bwo kwimura abantu mu buryo bwizewe kandi bunoze. Ingaruka z’amafaranga zo kwimura abantu mu buryo budacunzwe neza cyangwa ibyago bitamenyekanye zishobora kuba mbi cyane. Gushora imari mu majwi y’inganda asobanutse neza bituma habaho kubahiriza amabwiriza akomeye y’umutekano mu kazi no kunoza imikorere ya buri munsi.

Ikoreshwa ry'ingenzi ry'abavuga rikijyana mu by'inganda

Uburyo bwo gukora neza kw'indangururamajwi za PA mu nganda butuma ikora imirimo myinshi y'ingenzi mu kigo kimwe. Imiterere y'amajwi agezweho, cyane cyane akoresha ikoranabuhanga rya IP / SIP (Session Initiation Protocol), yemerera umuyoboro umwe w'indangururamajwi gucunga porogaramu zitandukanye, zashyizwe imbere icyarimwe. Gusobanukirwa izi ngingo z'ibanze ni ingenzi mu kugena ahantu nyaho, guhitamo indangururamajwi, n'ingamba zo guhuza ikigo.

Ibimenyesha abantu ku bijyanye no gushakisha amakuru yihutirwa no gushakisha amakuru ku bijyanye no kuva mu rugo

Uburyo bw'ingenzi cyane bwo gukoresha umuvugizi w’inganda ni ugutanga amakuru y’ubutabazi bw’igihe gito n’amapaji y’umutekano. Mu gihe habaye inkongi y’umuriro, imyuka yangiza cyangwa ikirere kibi cyane,Sisitemu ya PA igomba guhinduraizindi nzira zose z’amajwi. Inzego zigenzura, nka NFPA (Ishyirahamwe ry’Igihugu rishinzwe Kurinda Inkongi z’Umuriro) na OSHA, zitegeka ibipimo bihamye by’imikorere kuri izi sisitemu. By’umwihariko, amajwi y’ubutabazi n’amabwiriza y’ijwi bigomba kurenga nibura urwego rw’urusaku rwo mu kirere ho dB 15, cyangwa bikagera kuri dB 120, kugira ngo abakozi bambaye ubwirinzi bwo kumva babibone.

Uburyo bwo gusohora amajwi bushingiye cyane ku buryo ijwi ry’inganda rishobora kumvikana neza. Nubwo amajwi asanzwe agaragaza ko hari ibyago bisanzwe, amabwiriza y’ijwi ashobora kuyobora abakozi kuva mu bice runaka by’akaga cyangwa akabategeka kwihisha aho bari. Ibi bisaba ko amajwi ashobora kongera kugaragara neza mu buryo ijwi ry’umuntu rishobora gukwirakwira (kuva kuri 300 Hz kugeza kuri 4 kHz) mu buryo bwumvikana cyane, bikagabanya guhindagurika ndetse no ku rugero ntarengwa rw’umusaruro.

Itumanaho ry'Umusaruro n'Ivugurura ry'Imikorere

Uretse ibibazo byihutirwa, abavuga rikijyana mu nganda borohereza umuvuduko w’ibikorwa bya buri munsi. Ibigo bikoresha ubu buryo mu gutanga amakuru ku mpinduka z’akazi, gutangaza igihe cyo kuruhuka, no kwandika ku mbuga zigenewe abakozi bashinzwe kubungabunga cyangwa abashinzwe kugenzura. Mu gushyiraho uturere dutandukanye tw’amajwi, ubuyobozi bushobora kwandika ku mirongo yihariye y’ibikorwa cyangwa amashami runaka nta kubangamira uruganda rwose.

Guhuza neza bituma sisitemu ya PA iba inyongera y’imikorere yikora. Urugero, iyo imashini runaka igize ikibazo, sisitemu yo kugenzura ishobora gutera ubutumwa bwafashwe mbere cyangwa ubutumwa bwakozwe bugashyirwa gusa mu gace gakorerwamo ibikorwa. Ubu buryo bugamije kugabanya "umunaniro w'inkuba" ubaho iyo abakozi bahora bakorerwa impapuro zitandukanye n'inshingano zabo. Gushyira mu bikorwa uburyo bwo gushyira mu byiciro bishobora kugabanya kubangamira amajwi bitari ngombwa kugeza kuri 70%.

Amatangazo ku bubiko n'ibicuruzwa

Ibigega n'aho ibikoresho bikorerwa ibintu bitanga imbogamizi zidasanzwe z'amajwi bitewe n'uburebure bwabyo bunini, ibisenge birebire, n'imirongo y'ibice binini, bishobora kwakira cyangwa kugaragaza amajwi mu buryo butunguranye. Abavuga rikijyana mu nganda muri ibi bice ni ingenzi mu guhuza urujya n'uruza rw'imodoka zitwara imizigo, kuyobora amakamyo y'ubwikorezi yinjira ku byambu byihariye byo gupakira imizigo, no gucunga imikorere y'ibikoresho.

Mu bubiko burimo ububiko bunini, indangururamajwi zikunze kumanikwa ku gisenge cyangwa zigashyirwa hejuru ku nkingi z’inyubako kugira ngo amajwi ajye hasi, yinjire mu nzira. Indangururamajwi ifite ijwi rirenga ishobora gutwikira neza ubuso bwa metero kare 5.000 kugeza ku 10.000 bitewe n’urusaku rw’ahantu n’imiterere y’aho ibintu biherereye. Itumanaho rikora neza rigabanya igihe abashoferi bamara bategereje ko ibikoresho bishyirwa ku cyambu kandi rigatuma abakozi bashinzwe ibikoresho bihutira koherezwa mu duce dukeneye kongeramo ibikoresho byihutirwa.

Ibisobanuro by'Umuvugizi w'Inganda wa PA ugomba kugereranya

Guhitamo indangururamajwi zikwiye zo mu nganda bisaba isuzuma rikomeye ry’imiterere y’amajwi n’imiterere y’umubiri. Kwishingikiriza ku bushobozi bwo gutanga amakuru gusa ni ikosa rikunze kugaragara mu gutanga amakuru; uburebure bw’amajwi bugaragaza gusa ikoreshwa ry’amashanyarazi, ntabwo ari ingano nyayo cyangwa uburyo ijwi rigaragara neza. Ahubwo, abahanga mu by’amajwi n’abayobozi b’ibigo bagomba gusuzuma imiterere y’imiterere igena uko indangururamajwi izakora mu nganda runaka.

Uburyo amajwi akwirakwira, umuvuduko wayo, n'uburyo yumva ibintu neza

Igipimo nyacyo cy'ijwi ry'umuvugizi ni urugero rw'umuvuduko w'ijwi (SPL), ubusanzwe rupimirwa muri decibels (dB) ku ngufu za watt 1 uvuye kuri metero 1. Indangururamajwi ya PA y'inganda igomba kugira ubushobozi bwo kumva ibintu byinshi, akenshi ikaba ifite amanota ya SPL ari hagati ya 105 dB na 115 dB (1W/1m). Ibi byemeza ko indangururamajwi ishobora gukora ingano nini ikenewe kugira ngo itsinde urusaku rukomeye rw'imashini idasaba imbaraga nyinshi zo gutera inkunga.

Ariko, ijwi ntacyo rimaze hatabayeho gusobanuka neza. Gusobanukirwa neza bipimwa hakoreshejwe uburyo bwo gupima imvugo (STI), igipimo kuva kuri 0 kugeza kuri 1.0. Ku itumanaho ryihutirwa mu nganda, amanota ya STI ya 0.5 cyangwa irenga ni yo asabwa muri rusange. Kugira ngo umuntu agere kuri aya manota bisaba umuvugizi ufite uburyo bwo gusubiza neza inshuro zigaragara, ashimangira amajwi y’inyajwi, hamwe n’aho ashyirwa neza kugira ngo agabanye guhindagurika kw’ijwi n’amajwi ahurirana avangavanga amajwi.

Isuzuma rya IP, Igenzura ry'ikirere, no Kuramba

Ibidukikije by’inganda bishyira ibikoresho mu bintu bikomeye, bigatuma ibipimo by’ingenzi byo kurinda kwinjira mu kirere (IP) na NEMA. Igipimo cya IP kigizwe n’imibare ibiri: icya mbere kigaragaza uburinzi ku bintu bikomeye (umukungugu), n’icya kabiri kikarwanya ibinyobwa. Indangururamajwi isanzwe y’inganda igomba kugira igipimo cya IP66, bigaragaza ko idafunze neza kandi irinzwe n’inyanja nyinshi cyangwa amazi menshi—ni ngombwa ku bikoresho bisaba amazi menshi.

Muri Amerika ya Ruguru, amanota ya NEMA akunze gukoreshwa. Amanota ya NEMA 4X ni meza cyane, kuko akingira ivumbi rihuhwa n'umuyaga, imvura, amazi asukwa, kandi icy'ingenzi ni ingese.ibidukikije biteje akagaAho imyuka cyangwa umukungugu bishobora gushya, nk'inganda zikora peteroli cyangwa ascenseur z'ibinyampeke, indangururamajwi zigomba kuba zifite ibyangombwa byihariye bidashobora guturika (urugero: ATEX, IECEx, cyangwa Class I, Division 1/2). Izi mashini zifite ahantu hakomeye kandi hadashya umuriro hagenewe gushyiramo umuriro w'amashanyarazi imbere, bikayirinda gutwika ikirere cyo hanze.

Abavuga Ijwi ry'Ihembe vs Abavuga Ijwi ry'Abaminisitiri

Imiterere y’ikirangurura cy’inganda cya PA ni yo igena uburyo gikwirakwira mu ijwi ry’ijwi n’uburyo gikoreshwa neza. Ibintu bibiri bikunze kugaragara ni indangururamajwi zikoresha amajwi n’amajwi yo mu kabati (cyangwa ashyiraho hejuru y’amazi). Indangururamajwi zikoresha agace k’amajwi gafite umuvuduko wo hejuru kugira ngo zongere ijwi ry’umushoferi, bigatuma ijwi rye rigira SPL nyinshi cyane kandi rikagira icyerekezo cyiza. Zikora neza cyane ariko akenshi ntizikoresha amajwi menshi, bigatuma ziba nziza cyane mu gutanga amajwi arambuye no mu gutanga amajwi asobanutse neza mu bice by’urusaku n’ibinini.

Abavugizi b'inama y'abaminisitiri, ku rundi ruhande, bakoresha agasanduku gasanzwe, gakunze kubamo abashoferi benshi (woofer na tweeter). Batanga igisubizo cyagutse kandi bakagira amajwi meza muri rusange, bigatuma baba bakwiye gukorerwa umuziki wo inyuma no gucuranga amajwi mu bice by'inganda bituje nko mu byumba byo kuruhukiramo, muri laboratwari, cyangwa mu bice byo gupakira. Ariko, ntibafite imbaraga zo guhangana n'ikirere nk'uko ihoni ryihariye ry'inganda ribikora.

Gutegura no gushyiraho sisitemu y'umuvugizi w'inganda (Industrial PA)

Kugura ibikoresho bikwiye ni kimwe cya kabiri cy'ikigereranyo; imikorere ya sisitemu y'indangururamajwi ya PA mu nganda ishingiye gusa ku igenamigambi ry'abahanga, gushyira mu bikorwa ingamba, no gushyiraho neza amabwiriza yo gushyiraho. Amajwi mu nganda ntababarira cyane. Gushyira mu bikorwa nabi bishobora gutuma habaho uduce duto aho amakuru y'ingenzi atumvikana, cyangwa aho amajwi ahurirana bigatuma amajwi atumvikana neza.

Isuzuma ry'ahantu, Gushyira imiterere y'ahantu, n'aho abavuga baherereye

Ishingiro ry'ishyirwaho ry'urusaku rwagutse ni ubushakashatsi burambuye ku hantu hakorerwa amajwi. Abahanga mu by'ubwubatsi bagomba gupima urusaku rwo mu kirere mu nzego zitandukanye z'imikorere no gushushanya ingano y'aho hantu. Kubera ko amajwi akurikiza itegeko rya kare rihindagurika—rikagabanukaho 6 dB buri gihe intera uvuye ku ndangururamajwi yikubye kabiri—abahanga mu by'ubwubatsi bagomba kubara neza umubare w'indangururamajwi zikenewe kugira ngo SPL ikomeze kuba nziza mu igorofa ryose.

Gushyira ku murongo ni intambwe ikomeye ikurikiraho. Ibikoresho bigomba kugabanywamo ibice by’amajwi bishingiye ku rusaku rwo mu kirere n’imikorere yacyo. Kugira ngo habeho uburyo bumwe bwo gukwirakwira no kwirinda ahantu hapfuye, indangururamajwi zishyirwa hagati ya metero 15 na 20 (metero 50 kugeza kuri 65) mu duce tw’urusaku rwinshi. Aho kwishingikiriza ku ndangururamajwi nini nke zivuza ku ijwi ritagira umuvuduko mwinshi, bigatuma habaho ahantu hashyuha cyane kandi humvikana neza, uburyo bwiza bwo gukoresha amajwi akwirakwijwe butegeka gukoresha indangururamajwi nyinshi zikoresha amajwi ku buryo bwa wattage nke.

Guhuza na sisitemu yo gutanga amakuru ku nkongi y'umuriro n'umutekano

Mu nganda, sisitemu ya PA ntabwo iba ari umuyoboro wihariye; igomba guhuza neza n'ibikoresho byo kugenzura umutekano w'ubuzima bw'ikigo n'ibijyanye n'inkuba (FACP). Uku guhuza gutuma iyo inkuba itangiye, sisitemu ya PA ihita ifunga umuziki wose wo inyuma cyangwa paging isanzwe kandi igatangaza amabwiriza yo guhunga yafashwe mbere. Ibi bisaba gufunga by'umwihariko cyangwa guhuza API ku rwego rw'umuyoboro hagati ya sisitemu zombi.

Kugira ngo ubuzima bukomeze kubahiriza amategeko, imirongo y'indangururamajwi ubwayo igomba gukurikiranwa buri gihe kugira ngo harebwe amakosa. Indangururamajwi zigezweho zikoresha uburyo bwo kugenzura impedance cyangwa resistor za EOL kugira ngo zimenye imiyoboro migufi, imirongo ifunguye, cyangwa impanuka z'indangururamajwi. Iyo forklift iciye insinga y'indangururamajwi mu cyumba cy'ububiko, sisitemu igomba guhita imenyesha ikibazo mu cyumba cyo kugenzura, ikareba ko sisitemu isana mbere y'uko hagira ikibazo.

Iyubahirizwa ry'amategeko, Isuzuma n'Inyandiko

Gushyira sisitemu y’indangururamajwi ya PA mu nganda bigengwa n’amategeko akomeye. Mu Burayi, sisitemu zikoreshwa mu gukuraho amajwi zigomba kubahiriza amahame ya EN 54-24, agena imikorere ihamye n’ibipimo byo kubaho ku ndangururamajwi ubwazo. Muri Leta Zunze Ubumwe za Amerika, NFPA 72 igenzura ishyirwaho, imikorere, n’igeragezwa ry’uburyo bwo gutanga amakuru y’inkongi y’umuriro n’itumanaho ryihutirwa.

Nyuma yo gushyiraho, gukoresha neza no gupima ni itegeko. Abatekinisiye bagomba gukora ibipimo by'amajwi bakoresheje metero za SPL na STI analyzers zagenzuwe kugira ngo bemeze ko sisitemu yujuje ubunini n'ubushobozi bwo gusobanukirwa mu turere twose. Ibisubizo byose by'ibizamini, amakarita y'uturere, imbonerahamwe z'insinga, n'ibipimo by'ibanze bya impedance bigomba kwandikwa neza. Iyi nyandiko ni yo shingiro ry'ibizamini bya buri mwaka kandi ikerekana ko kwagura inyubako mu gihe kizaza bitabangamira ubusugire bw'urusobe rw'amajwi mu mutekano w'ubuzima.

Uburyo bwo guhitamo igisubizo cy'umuvugizi w'inganda (PA)

Gukoresha isoko kugira ngo uboneigisubizo cy'umuvugizi w'inganda wa PAbisaba kuringaniza ibikenewe byihuse mu gusohora amajwi n'igenamigambi ry'ibikorwa remezo ry'igihe kirekire. Abayobozi b'ibigo n'amatsinda ashinzwe gutanga amasoko bagomba gusuzuma sisitemu zishobora gukoreshwa atari ku mpapuro zabo gusa, ahubwo no kureba uburyo zihuzwa neza n'ibikorwa remezo by'ikoranabuhanga by'ikigo, ubushobozi bwo kubungabunga, na gahunda zo kwagura mu gihe kizaza.

Ibipimo ngenderwaho mu gufata ibyemezo ku bidukikije by'inganda

Ibipimo by'ingenzi bishingira ku guhitamo hagati ya sisitemu gakondo za analog (70V/100V) n'imiyoboro igezweho y'amajwi ishingiye kuri IP. Iyo ikigo gifite insinga z'umuringa zisanzweho, nziza kandi gisaba sisitemu yoroshye kandi ihuriweho ya paging, sisitemu isanzwe ya 70V ikomeza kuba nziza kandi ikomeye. Ariko, niba ikigo gisaba ko habaho imiterere y'amajwi, guhuza porogaramu mu buryo bwikora, no kugenzura kure, sisitemu ishingiye kuri IP/SIP ni nziza cyane.

Indangururamajwi za PA zishingiye kuri IP zihuza neza na network y’aho hantu (LAN) binyuze mu nsinga zisanzwe za Ethernet. Inyinshi muri zo zikoresha Power over Ethernet (PoE cyangwa PoE+), zigakura amakuru ndetse zikanakuramo watts 30 z’ingufu kuri cable imwe. Ibi bigabanya cyane akazi ko gushyiramo kandi bigakuraho gukenera amplifier nini zihuriweho. Abafata ibyemezo bagomba gusuzuma ubushobozi bwa bandwidth y’ishami ryabo ry’ikoranabuhanga n’imiterere y’umutekano w’ikoranabuhanga mbere yo gukoresha amagana y’amajwi afatanye na network.

Igiciro cyose cy'ubufasha bw'abatanga serivisi n'ababakorera

Mu gusuzuma Ikiguzi cyose cy’Ubucuruzi (TCO), amafaranga akoreshwa mu byuma mbere y’igihe akoreshwa ni igice gito cyane cy’ikiguzi cy’ubuzima bwose. Inganda zigabanya ibikoresho vuba; bityo, gushyira imbere indangururamajwi zifite igihe cyo hagati y’igihe cyo gutsindwa (MTBF) kirenga amasaha 50.000 ni ingamba nziza y’imari. Indangururamajwi zihendutse zizakenera gusimburwa kenshi, bikongera ikiguzi cy’abakozi kandi bigasaba gukodesha amakasi ahenze ku zindi nzu nini.

Hanyuma, suzuma inkunga y'utanga serivisi nyuma yo kugurisha n'imiterere y'ingwate. Uruganda ruzwiho gukora ibikoresho by'amajwi mu nganda rugomba gutanga ubufasha bwuzuye mu gushushanya, inkunga ya porogaramu yo kwerekana amajwi, n'igihe gito cy'ingwate kuva ku myaka 3 kugeza kuri 5 ku bikoresho bikomeye. Ubufasha bukomeye bw'utanga serivisi butuma uko ikigo kigenda gitera imbere, sisitemu ya PA ishobora kwagurwa no kunozwa neza nta kibazo gisaba kuvugurura ibikorwa remezo.
