大型酒店商場無(wu)線(xian)通訊覆蓋解決方(fang)案

（摩托羅拉，海能達，建伍，科立訊）無(wu)線對講系統設計方案，安裝調試：

無線對(dui)講設備生產(chan)廠(chang)家:中繼臺，對(dui)講機， 發射合路(lu)器(qi)(qi)、接收分路(lu)器(qi)(qi)、寬帶雙工器(qi)(qi)、干(gan)線放大器(qi)(qi)、光(guang)纖(xian)近端機、光(guang)纖(xian)遠(yuan)端機、耦合器(qi)(qi)、功分器(qi)(qi)、室外天線、室內天線、避(bi)雷器(qi)(qi)、饋線連(lian)接器(qi)(qi)、射頻同軸電纜(lan)、連(lian)接器(qi)(qi)等

酒店、商場、娛樂場所等情況

一般(ban)酒店(dian)、商場(chang)占(zhan)地(di)面積較大，分(fen)為地(di)面層加地(di)下停車(che)場(chang)，各(ge)項(xiang)電子設施(shi)的(de)投入使用(yong)，人流(liu)量(liang)的(de)量(liang)大，以及各(ge)色包間的(de)封閉性，安全(quan)保(bao)(bao)衛工(gong)作和供電、電梯、消防工(gong)程保(bao)(bao)障工(gong)作的(de)進(jin)一步(bu)落實(shi)，應付(fu)突發性事件的(de)處理，都離不開快速反應的(de)無線電對(dui)講調度聯系。簡單(dan)的(de)對(dui)講機遠(yuan)遠(yuan)不能滿足(zu)管理工(gong)作的(de)需要，必須(xu)要進(jin)一步(bu)完善和改造，通(tong)過改造才(cai)能滿足(zu)隨叫隨通(tong)，大范圍和地(di)下室聯系均有保(bao)(bao)障的(de)通(tong)話效(xiao)果(guo)。

二、 對講系統完善和改造方案

針對(dui)(dui)(dui)酒店情(qing)況采(cai)用(yong)(yong)無線(xian)(xian)中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)來(lai)擴大(da)對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機的(de)(de)(de)通(tong)(tong)(tong)(tong)(tong)信(xin)范圍的(de)(de)(de)原理是(shi)這樣的(de)(de)(de)。中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)由收(shou)信(xin)機和發(fa)(fa)(fa)(fa)信(xin)機等單元(yuan)組成。通(tong)(tong)(tong)(tong)(tong)常工(gong)作于收(shou)發(fa)(fa)(fa)(fa)異(yi)頻(pin)狀態，能夠將(jiang)收(shou)發(fa)(fa)(fa)(fa)到(dao)的(de)(de)(de)已調(diao)制的(de)(de)(de)射(she)頻(pin)信(xin)號(hao)解調(diao)出音頻(pin)信(xin)號(hao)傳(chuan)輸給(gei)其他設備。同時(shi)、還能將(jiang)其它(ta)設備送(song)來(lai)的(de)(de)(de)音頻(pin)信(xin)號(hao)經射(she)頻(pin)調(diao)制后發(fa)(fa)(fa)(fa)射(she)出去(qu)。上面提到(dao)的(de)(de)(de)其它(ta)設備有各種系統使用(yong)(yong)的(de)(de)(de)控制器，有無線(xian)(xian)接駁(bo)器等，也包括互聯網(wang)所需要的(de)(de)(de)其它(ta)中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)。將(jiang)中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)收(shou)到(dao)的(de)(de)(de)信(xin)號(hao)直接通(tong)(tong)(tong)(tong)(tong)過(guo)自身的(de)(de)(de)發(fa)(fa)(fa)(fa)射(she)機轉發(fa)(fa)(fa)(fa)出去(qu)，這就是(shi)中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)最基本的(de)(de)(de)應用(yong)(yong)。例如：若(ruo)對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機甲(jia)與(yu)對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機乙(yi)(yi)之間由于距(ju)(ju)離比較遠(yuan)而無法(fa)實現通(tong)(tong)(tong)(tong)(tong)信(xin)。在(zai)采(cai)用(yong)(yong)無線(xian)(xian)中(zhong)(zhong)(zhong)(zhong)繼(ji)方(fang)法(fa)后，則(ze)當(dang)對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機甲(jia)發(fa)(fa)(fa)(fa)信(xin)時(shi)，對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機甲(jia)通(tong)(tong)(tong)(tong)(tong)過(guo)上行(xing)(xing)頻(pin)率將(jiang)信(xin)號(hao)發(fa)(fa)(fa)(fa)給(gei)中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)，中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)再通(tong)(tong)(tong)(tong)(tong)過(guo)下行(xing)(xing)頻(pin)率將(jiang)信(xin)號(hao)發(fa)(fa)(fa)(fa)給(gei)對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機乙(yi)(yi)。而當(dang)對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機乙(yi)(yi)發(fa)(fa)(fa)(fa)信(xin)時(shi)，對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機則(ze)通(tong)(tong)(tong)(tong)(tong)過(guo)上行(xing)(xing)頻(pin)率將(jiang)信(xin)號(hao)發(fa)(fa)(fa)(fa)給(gei)中(zhong)(zhong)(zhong)(zhong)繼(ji)臺(tai)(tai)(tai)(tai)，再通(tong)(tong)(tong)(tong)(tong)過(guo)下行(xing)(xing)頻(pin)率將(jiang)信(xin)號(hao)發(fa)(fa)(fa)(fa)給(gei)對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機甲(jia)。由此擴大(da)了對(dui)(dui)(dui)講(jiang)(jiang)(jiang)(jiang)機之間的(de)(de)(de)通(tong)(tong)(tong)(tong)(tong)信(xin)距(ju)(ju)離。

1、采用(yong)中(zhong)繼臺(tai)方(fang)式解決大(da)范圍(wei)和(he)地下室深(shen)層次通信保障方(fang)案(an)，見方(fang)案(an)圖：

2、工(gong)作(zuo)過程(cheng)

所(suo)有手(shou)持(chi)(chi)臺工作均(jun)通過(guo)中繼臺接(jie)力轉(zhuan)發信號，由于中繼臺是立即使轉(zhuan)發信號的，不(bu)會有停頓(dun)的感覺，就象手(shou)持(chi)(chi)與手(shou)持(chi)(chi)直呼一樣，但通話距離和(he)信號遠遠大(da)過(guo)手(shou)持(chi)(chi)與手(shou)持(chi)(chi)直呼，話音也清晰得多，電(dian)波(bo)穿透性(xing)能也強得多。

3、本系(xi)統(tong)(tong)設計(ji)使(shi)信(xin)號在有關空間區域內即對講信(xin)號有效覆蓋(gai)(gai)區域為地上建筑以及對講信(xin)號有效覆蓋(gai)(gai)大樓設備房(fang)及室(shi)外全樓，以確保無線對講系(xi)統(tong)(tong)通信(xin)之清晰(xi)、暢通，使(shi)整個系(xi)統(tong)(tong)達到覆蓋(gai)(gai)均勻，信(xin)號清晰(xi)，穩定可靠。
