傳統(tǒng)對講分機(jī)結(jié)構(gòu)分成分機(jī)底座及分機(jī)手柄。 </p> <p> <br /> </p> <p> A、分機(jī)底座主要功能：固定分機(jī)位置，分機(jī)底座有螺釘固定位（根據(jù)廠家不同，分機(jī)有直接通過底座的螺釘孔進(jìn)行安裝，也有分機(jī)通過在分機(jī)后面的背板進(jìn)行安裝）。在分機(jī)底座上（或者部分廠家在分機(jī)安裝背板上）有接線柱，用來連接從主機(jī)－分機(jī)的電纜。分機(jī)底座內(nèi)部有電路板，對分機(jī)部分功能進(jìn)行控制。 </p> <p> <br /> </p> <p> B，無錫數(shù)字樓宇對講施工、分機(jī)手柄：分機(jī)手柄內(nèi)部有喇叭和咪頭，用來接收語音及發(fā)送語音。 </p> <p> <br /> </p> <p> 分機(jī)面殼上會有多個按鍵，根據(jù)分機(jī)功能的不同，按鍵數(shù)量將有所變化，但是**基本的功能按鍵是必不可少的。如：開鎖按鍵，無錫數(shù)字樓宇對講施工、呼叫按鍵，無錫數(shù)字樓宇對講施工。開鎖按鍵主要功能是主機(jī)呼叫分機(jī)后，分機(jī)通過此按鍵開啟門口電控鎖；呼叫按鍵主要在數(shù)字式聯(lián)網(wǎng)系統(tǒng)中，當(dāng)住戶按動分機(jī)的呼叫按鍵時，管理中心可以顯示住戶房間號碼。

4)起源：由于樓宇對講系統(tǒng)是舶來品，國內(nèi)廠家在進(jìn)行參照研制的過程中必定收到原產(chǎn)品的影響。首先進(jìn)入國內(nèi)的產(chǎn)品為中國中國臺灣、韓國、日本產(chǎn)品（我在這里稱之為亞洲系統(tǒng)），基本均采用以上說的分機(jī)內(nèi)解碼的方式；94-98年進(jìn)入中國的產(chǎn)品很多包括西班牙、意大利等國的產(chǎn)品（我在這里稱之為歐洲系統(tǒng)），基本上是采用以上說明的外置解碼器的解碼方式。國內(nèi)產(chǎn)品中也出現(xiàn)了以上的兩種系統(tǒng)，下面就兩種系統(tǒng)的區(qū)別與優(yōu)缺點及相關(guān)的改進(jìn)介紹一下： </p> <p> <br /> </p> <p> 5)外置解碼：外置解碼器的樓宇對講系統(tǒng)有單一的解碼器，門口主機(jī)通過主線連接（串聯(lián)）單元內(nèi)所有的解碼器，再從解碼器分線進(jìn)入住戶室內(nèi)，連接住戶分機(jī)。解碼器基本功能包括：解碼、存儲地址信息、故障隔離、故障指示、音頻選通等。由于本身包括故障隔離及故障指示功能，單一住戶分機(jī)出現(xiàn)的問題基本不影響解碼器的正常工作，故障隔離功能對于樓宇對講系統(tǒng)的維護(hù)、保養(yǎng)等均有非常大的好處。但是相對來將，布線將稍微煩瑣一點。

判斷：如果系統(tǒng)音頻出現(xiàn)問題，通過音頻的單向可以了解到是分機(jī)－主機(jī)的音頻線路問題，還是主機(jī)－分機(jī)的音頻線路問題（分機(jī)能夠聽到主機(jī)通話，而主機(jī)不能聽到分機(jī)通話，或相反）。 </p> <p> <br /> </p> <p> 2)將音頻主呼通道及音頻應(yīng)答通道使用單一的線路傳輸，通過復(fù)用的技術(shù)進(jìn)行雙工通話。由于采用單線傳輸，線路相對于雙線傳輸減少一根。 </p> <p> <br /> </p> <p> 樓宇對講主要設(shè)備有哪些（9）視頻通道 </p> <p> <p> 指主機(jī)所攝圖像傳輸?shù)椒謾C(jī)監(jiān)視器的通道 </p> <p> <br /> </p> <p> 通常的樓宇對講系統(tǒng)的視頻通道是與系統(tǒng)的通訊、音頻通道完全分開的，采用電視監(jiān)控的視頻傳輸原理進(jìn)行通道的設(shè)計。由于樓宇對講系統(tǒng)相當(dāng)于一點對多點的視頻傳輸系統(tǒng)，在保證視頻傳輸清晰的前提下需要保證每條視頻通道的阻抗匹配（75歐姆）。在樓宇對講系統(tǒng)中，視頻分配器是系統(tǒng)視頻通道中一個必不可少的器件。視頻分配器的功能主要是對一個視頻信號進(jìn)行多路分配，并保證系統(tǒng)中任一視頻通道的視頻阻抗匹配的均衡。
