“酒店賓館公共廣播”解決方案

隨著我國對外(wai)改革開(kai)放的(de)(de)進一(yi)步深入,酒店賓(bin)館的(de)(de)建設(she)在我國已掀起(qi)一(yi)個高潮。再(zai)加上近(jin)年(nian)來(lai)各種(zhong)新(xin)技術、新(xin)方法的(de)(de)不斷(duan)出現,特別是(shi)近(jin)年(nian)來(lai)弱電系統發展(zhan)得(de)特別快,如何做好新(xin)時期建筑特別是(shi)星級賓(bin)館的(de)(de)弱電系統設(she)計,是(shi)擺在我們電氣設(she)計人員面前的(de)(de)新(xin)課題。

酒店(dian)公共(gong)廣(guang)播,賓館公共(gong)廣(guang)播系統(tong)的設置原則

我(wo)們(men)知道,建筑(zhu)的音響系(xi)統一般可分為以(yi)下三(san)種:

n業務性(xing)廣播(bo)系統

n服務性廣(guang)播系統

n火災(zai)事故廣播系統(tong)

根(gen)據《民(min)用建(jian)筑電氣設(she)(she)計規范》要求,酒店賓(bin)館公共廣(guang)播(bo)系(xi)統應(ying)設(she)(she)置服務(wu)性廣(guang)播(bo)系(xi)統和(he)火災事故(gu)廣(guang)播(bo)系(xi)統。服務(wu)性廣(guang)播(bo)系(xi)統應(ying)以滿足欣賞性音樂類廣(guang)播(bo)為主,且節目設(she)(she)置不(bu)宜(yi)超(chao)過五套。賓(bin)館的服務(wu)性廣(guang)播(bo)系(xi)統包括背景音樂和(he)客房音響。

專(zhuan)業音(yin)(yin)響(xiang)工程背(bei)景音(yin)(yin)樂和客(ke)房公(gong)共廣(guang)播系統的設計

星級賓館應在辦公(gong)室、走廊、門(men)廳及公(gong)共(gong)場所設置(zhi)背景(jing)音樂(le)(le)。背景(jing)音樂(le)(le)揚(yang)聲器一般(ban)選用3W~5W。客房音響(xiang)系統(tong)顧名思義是在客房內設置(zhi)供客人休息、時收聽的(de)音樂(le)(le)節(jie)(jie)目。前面(mian)已經說過,節(jie)(jie)目的(de)設置(zhi)一般(ban)不超過五套。

揚聲設備的選擇(ze)

背景(jing)(jing)音(yin)樂系統(tong)平(ping)時(shi)主要播送(song)背景(jing)(jing)音(yin)樂,給人們提供(gong)一個良好(hao)的(de)辦公、學習環境。在辦公室、生活間(jian)(jian)、更衣室等(deng)房(fang)間(jian)(jian)內可(ke)按(an)0.05W/m2左右(you)(you)裝(zhuang)設。一般(ban)(ban)會議室、餐廳(ting)、商場(chang)等(deng)大開(kai)間(jian)(jian)宜裝(zhuang)設1W~3W揚聲(sheng)器。層高(gao)(gao)為2.5m左右(you)(you)時(shi),采用(yong)1W揚聲(sheng)器;層高(gao)(gao)為4m以(yi)上時(shi),采用(yong)3W揚聲(sheng)器。間(jian)(jian)距均為層高(gao)(gao)的(de)2.5倍(bei)左右(you)(you)。走道揚聲(sheng)器問(wen)距按(an)層高(gao)(gao)的(de)2.5倍(bei)左右(you)(you)考慮。客房(fang)音(yin)響系統(tong)一般(ban)(ban)是(shi)在每間(jian)(jian)標準客房(fang)內裝(zhuang)設1W的(de)揚聲(sheng)器。揚聲(sheng)器一般(ban)(ban)均吸頂安裝(zhuang)。

音頻(pin)傳輸方式的選擇

音頻(pin)傳輸(shu)(shu)(shu)(shu)方(fang)式(shi)一般有兩種:定(ding)壓輸(shu)(shu)(shu)(shu)出(chu)(chu)方(fang)式(shi)和定(ding)阻(zu)(zu)(zu)輸(shu)(shu)(shu)(shu)出(chu)(chu)方(fang)式(shi)。定(ding)壓輸(shu)(shu)(shu)(shu)出(chu)(chu)廣(guang)播(bo)(bo)范圍大,用(yong)(yong)(yong)戶(hu)增(zeng)減較(jiao)(jiao)方(fang)便;定(ding)阻(zu)(zu)(zu)輸(shu)(shu)(shu)(shu)出(chu)(chu)的(de)(de)廣(guang)播(bo)(bo)范圍較(jiao)(jiao)小(xiao),配線簡(jian)單(dan)而且(qie)音質較(jiao)(jiao)好。但由于定(ding)阻(zu)(zu)(zu)輸(shu)(shu)(shu)(shu)出(chu)(chu)網(wang)絡阻(zu)(zu)(zu)抗計算較(jiao)(jiao)麻煩,切(qie)除(chu)用(yong)(yong)(yong)戶(hu)揚聲(sheng)器時必須用(yong)(yong)(yong)相當的(de)(de)等值阻(zu)(zu)(zu)抗假性負載代替(ti)。因此只適用(yong)(yong)(yong)于廣(guang)播(bo)(bo)網(wang)較(jiao)(jiao)小(xiao)的(de)(de)場所。而星級賓(bin)館(guan)的(de)(de)廣(guang)播(bo)(bo)范圍都(dou)比(bi)較(jiao)(jiao)大,用(yong)(yong)(yong)戶(hu)也經(jing)常(chang)增(zeng)減廣(guang)播(bo)(bo)單(dan)元,因此星級賓(bin)館(guan)的(de)(de)廣(guang)播(bo)(bo)網(wang)絡一般都(dou)選用(yong)(yong)(yong)定(ding)壓輸(shu)(shu)(shu)(shu)出(chu)(chu),功率傳送。

客房音(yin)響系統的設計還有一種做法是把(ba)所有音(yin)響節目(mu)經調(diao)制(zhi)器混入(ru)共用(yong)天(tian)線系統,通過(guo)同(tong)軸(zhou)電纜送入(ru)客房,在(zai)床頭控制(zhi)柜(ju)上裝(zhuang)調(diao)頻(pin)接收機(ji)把(ba)音(yin)頻(pin)信號解(jie)調(diao)出(chu)節省設備。但每個(ge)房間使用(yong)不方(fang)便,現在(zai)大型賓館很(hen)少(shao)采用(yong)這種設計。

系統前(qian)端設備的(de)選擇與設置(zhi)

如前所述,星級(ji)賓館的(de)音(yin)響系統宜(yi)選(xuan)用定(ding)壓輸出,功(gong)率傳送。下(xia)面給出功(gong)放設備的(de)容量計算公式:

P=K1×K2×Σ0

式中(zhong),P----功(gong)放設備輸出的總電功(gong)率(lv);

P0=Ki×Pi,每分路同(tong)時廣播的(de)最大電功率;

p1----第(di)i支路設備的(de)額定容(rong)量;

Ki----第i支路(lu)的(de)同時需要系數;

客房音響系統(tong)每套取(qu)0.2~0.4;背景音樂系統(tong)取(qu)0.5~0.6;

K1線路衰耗補償系數(shu);賓館音響系統允許衰耗1dB,取1.26;

K2老化系數,一(yi)般取1.2~1.4。

例如:某(mou)三星級賓(bin)館(guan)有320套客(ke)房,按每間(jian)客(ke)房裝(zhuang)設(she)四套節目,使用1W揚(yang)聲器,則(ze)每套節目功放設(she)備的(de)容量計算如下:

P=K1×K2×ΣP0=1.26×1.4×(320×0.4)=226W

所以,每套(tao)節目可選擇(ze)2臺(tai)120W的功率放大器,四套(tao)節目共八臺(tai)即可滿足要求。

前端設備(bei)除了功放(fang)單元以外,還有(you)信(xin)號(hao)源、前置(zhi)增音機(ji)、監聽(ting)器等。信(xin)號(hao)源一(yi)般可(ke)選用立體聲調頻接收機(ji)、自動(dong)回(hui)帶播放(fang)錄音機(ji)、CD唱機(ji)等。前置(zhi)增音機(ji)的功能是(shi)把信(xin)號(hao)源來的不同電(dian)(dian)平(ping)的信(xin)號(hao)進行(xing)規(gui)整、放(fang)大(da),使不同信(xin)號(hao)源的電(dian)(dian)平(ping)在進入功放(fang)設備(bei)時基(ji)(ji)本(ben)一(yi)致,以保證每(mei)套節目(mu)的電(dian)(dian)平(ping)在放(fang)大(da)輸(shu)出后基(ji)(ji)本(ben)一(yi)致。

酒店背(bei)景音樂(le)系統,服務性廣播(背(bei)景音樂(le)和客房音樂(le))與火災(zai)事故(gu)廣播的關(guan)系

酒店賓館(guan)建(jian)筑的(de)服(fu)務(wu)性(xing)廣(guang)(guang)(guang)播(bo)與火(huo)(huo)災(zai)事故廣(guang)(guang)(guang)播(bo)均合用揚(yang)聲器(qi)。我國《火(huo)(huo)災(zai)自動報警系統(tong)設(she)(she)計規范(fan)》指出,火(huo)(huo)災(zai)時,應能在消(xiao)防控(kong)制室將(jiang)火(huo)(huo)災(zai)疏散層的(de)揚(yang)聲器(qi)和廣(guang)(guang)(guang)播(bo)音(yin)響擴(kuo)音(yin)機強(qiang)制轉入(ru)火(huo)(huo)災(zai)事故廣(guang)(guang)(guang)播(bo)狀態。賓館(guan)客(ke)房的(de)揚(yang)聲器(qi)應具有(you)火(huo)(huo)災(zai)事故廣(guang)(guang)(guang)播(bo)功能。因(yin)此,在具有(you)緊急廣(guang)(guang)(guang)播(bo)功能的(de)賓館(guan)廣(guang)(guang)(guang)播(bo)音(yin)響系統(tong)設(she)(she)計中,必須注意:

n消防(fang)報警信號應在系統(tong)中(zhong)具(ju)(ju)有(you)最高(gao)優先權,應具(ju)(ju)備切斷背景音(yin)樂和(he)客(ke)房音(yin)響等狀(zhuang)態(tai)的(de)功能;

n應便于消防報警(jing)值班人員(yuan)進行控制;

n傳輸電纜(lan)和揚聲器應具有防(fang)火特性(xing);

n最好(hao)設置(zhi)獨立的備(bei)用電(dian)源設備(bei),在(zai)交(jiao)流電(dian)斷電(dian)的情況(kuang)下(xia),保(bao)證報警廣播(bo)的實施。

因(yin)此,在(zai)(zai)設(she)計(ji)酒(jiu)店賓(bin)館公(gong)共廣播系(xi)統時如何使服務(wu)性(xing)廣播與(yu)火災事故(gu)廣播有(you)機結合,是在(zai)(zai)設(she)計(ji)時需要(yao)特(te)別(bie)考慮的問題。

其實(shi),實(shi)現(xian)(xian)這(zhe)(zhe)種(zhong)(zhong)(zhong)有(you)機結合的(de)(de)(de)方(fang)法很多,下(xia)面介紹一(yi)種(zhong)(zhong)(zhong)簡單實(shi)用的(de)(de)(de)做法:末(mo)端(duan)(duan)切(qie)(qie)換系統。我(wo)們知(zhi)道,無論是(shi)背景音樂還是(shi)客房音響,都是(shi)把信(xin)號(hao)送至揚(yang)聲(sheng)器,并(bing)在揚(yang)聲(sheng)器前(qian)端(duan)(duan)加(jia)上(shang)音量控制開(kai)關。為(wei)了使緊急廣播(bo)(bo)不(bu)受(shou)(shou)音量開(kai)關的(de)(de)(de)控制,現(xian)(xian)在火(huo)災(zai)(zai)報警(jing)控制系統都提供一(yi)種(zhong)(zhong)(zhong)帶地址編碼的(de)(de)(de)切(qie)(qie)換模(mo)(mo)塊,此切(qie)(qie)換模(mo)(mo)塊在正常情況(kuang)下(xia),接(jie)通服(fu)務(wu)性廣播(bo)(bo),一(yi)旦有(you)緊急情況(kuang),馬上(shang)能由(you)火(huo)災(zai)(zai)報警(jing)控制室強制切(qie)(qie)換到緊急廣播(bo)(bo)狀態。并(bing)可根據火(huo)災(zai)(zai)事故情況(kuang),指揮事故層(ceng)(ceng)的(de)(de)(de)上(shang)兩層(ceng)(ceng)及下(xia)一(yi)層(ceng)(ceng)人(ren)員疏散。由(you)于這(zhe)(zhe)種(zhong)(zhong)(zhong)系統的(de)(de)(de)信(xin)號(hao)是(shi)在末(mo)端(duan)(duan)切(qie)(qie)換的(de)(de)(de),所(suo)以稱之(zhi)為(wei)末(mo)端(duan)(duan)切(qie)(qie)換系統。需要指出的(de)(de)(de)是(shi),切(qie)(qie)換模(mo)(mo)塊必須(xu)在音量控制開(kai)關之(zhi)后,才能保證火(huo)災(zai)(zai)事故廣播(bo)(bo)的(de)(de)(de)最高優先權不(bu)受(shou)(shou)音量開(kai)關的(de)(de)(de)控制。這(zhe)(zhe)種(zhong)(zhong)(zhong)系統的(de)(de)(de)工(gong)作原理如下(xia)圖(tu):

酒店賓館公共廣播系統,音晌前端室的布置與設計

酒店賓館的(de)音響控(kong)制(zhi)(zhi)室(shi)一般均與(yu)有(you)線電視前端機房合用。這是因為他們(men)工作時間和服務對象差(cha)不多,合在一起(qi),可(ke)以減(jian)少管理人員,提高效率。大型音響系統的(de)前端一般設(she)有(you):機房控(kong)制(zhi)(zhi)室(shi)、錄播室(shi)、資料(liao)室(shi)、辦公室(shi)等。每間面積一般可(ke)控(kong)制(zhi)(zhi)在20m2左右(you)。機房控(kong)制(zhi)(zhi)室(shi)的(de)設(she)備(bei)布置應(ying)符合下列要求:

柜前凈(jing)距不小于1.5m,柜側與(yu)墻、柜和柜背(bei)與(yu)墻的凈(jing)距不應小于0.8m,柜側要維護時柜間(jian)距離不應小于1m。

音晌系統的線路敷設

酒店賓館一般(ban)均有弱電豎(shu)井(jing),為了減少每套節(jie)目(mu)(mu)的相(xiang)(xiang)互干(gan)(gan)擾和每套節(jie)目(mu)(mu)間的相(xiang)(xiang)互干(gan)(gan)擾,每套節(jie)目(mu)(mu)出(chu)線(xian)分別穿鋼(gang)管沿弱電豎(shu)井(jing)敷(fu)設。干(gan)(gan)線(xian)一般(ban)采用ZR-BV-500 2.5mm2或4mm2導線(xian),每層支線(xian)一般(ban)選用ZR-BV-500 1.5mm2導線(xian)穿鋼(gang)管沿吊頂內暗敷(fu)。

音晌系統的供電與接地

酒店賓館(guan)的電(dian)(dian)(dian)(dian)源(yuan)(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian)系統均有雙電(dian)(dian)(dian)(dian)源(yuan)(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian),因此(ci),在音(yin)響控制(zhi)室設(she)一配電(dian)(dian)(dian)(dian)箱(xiang),此(ci)配電(dian)(dian)(dian)(dian)箱(xiang)由雙路電(dian)(dian)(dian)(dian)源(yuan)(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian),末端互技,以保(bao)證音(yin)響控制(zhi)室的供(gong)(gong)電(dian)(dian)(dian)(dian)。另外,一般(ban)均設(she)有穩(wen)壓電(dian)(dian)(dian)(dian)源(yuan)(yuan)裝置及不間(jian)斷電(dian)(dian)(dian)(dian)源(yuan)(yuan)裝置,從(cong)而更好地保(bao)證供(gong)(gong)電(dian)(dian)(dian)(dian)可靠性及電(dian)(dian)(dian)(dian)能質量。

廣(guang)播(bo)控制室應(ying)設(she)(she)置(zhi)保護(hu)接(jie)地(di)和(he)工作(zuo)接(jie)地(di)。為減少供電系(xi)(xi)(xi)統對廣(guang)播(bo)音頻系(xi)(xi)(xi)統的(de)影(ying)響,保護(hu)接(jie)地(di)和(he)工作(zuo)接(jie)地(di)應(ying)分(fen)開設(she)(she)置(zhi)。推薦一(yi)種做(zuo)法(fa)是在(zai)弱(ruo)(ruo)電豎(shu)井和(he)強(qiang)電豎(shu)井內各敷設(she)(she)一(yi)根40×4的(de)銅帶(dai)分(fen)別作(zuo)為弱(ruo)(ruo)電系(xi)(xi)(xi)統的(de)工作(zuo)接(jie)地(di)和(he)強(qiang)電系(xi)(xi)(xi)統的(de)保護(hu)接(jie)地(di)。這種接(jie)地(di)在(zai)接(jie)入大(da)地(di)時是一(yi)點接(jie)地(di),總接(jie)地(di)電阻不得(de)大(da)于1Ω。這樣,就可使(shi)弱(ruo)(ruo)電系(xi)(xi)(xi)統更好地(di)工作(zuo)。
