A、分機底座主要功能：固定分機位置，分機底座有螺釘固定位（根據(jù)廠家不同，分機有直接通過底座的螺釘孔進行安裝，也有分機通過在分機后面的背板進行安裝）。在分機底座上（或者部分廠家在分機安裝背板上）有接線柱，用來連接從主機－分機的電纜。分機底座內(nèi)部有電路板，對分機部分功能進行控制。 </p> <p> <br /> </p> <p> B、分機手柄：分機手柄內(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> 分機面殼上會有多個按鍵，根據(jù)分機功能的不同，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、呼叫按鍵。開鎖按鍵主要功能是主機呼叫分機后，分機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，當住戶按動分機的呼叫按鍵時，管理中心可以顯示住戶房間號碼。無錫門禁樓宇對講機</p><div

在樓宇對講系統(tǒng)中使用的門禁系統(tǒng)一般采用感應式ID卡及感應式IC卡。小區(qū)一卡通一般采用感應式IC卡來完成（因為IC卡有比較強大的存儲功能，可將很多信息存儲在卡內(nèi)），IC卡目前通常采用LEGIC技術(shù)與MIFARE技術(shù)兩種。由于LEGIC技術(shù)卡在研制初期是使用在**領(lǐng)域內(nèi)，相比較而言，感應距離、可靠性、數(shù)據(jù)運算能力、抗干擾能力等均比MIFARE技術(shù)卡強，但由于價格的原因，MIFARE技術(shù)卡在實際中大量的應用。 </p> <p> <br /> </p> <p> 在樓宇對講系統(tǒng)中集成的門禁系統(tǒng)，由于讀卡部分必須在門口主機上，門口主機必須有一塊專門進行讀卡的部分。感應卡一般采用射頻技術(shù)，金屬的物體對于感應卡有屏蔽作用，從而影響卡的感應舉例。門口主機的感應卡部分必須采用非金屬質(zhì)地，以降低對門禁感應卡的屏蔽。 </p> <p> <br /> </p><p> 樓宇對講主要設備有哪些（5）網(wǎng)絡交換機 </p> <p> <p> 每個小區(qū)聯(lián)網(wǎng)時必須配匹一個，它是整個小區(qū)網(wǎng)絡資源管理器，對講時選用哪個通道、數(shù)據(jù)通信仲裁、通信信號中繼、協(xié)議變換等都要經(jīng)過交換機處理。 </p> <p> <br /> </p> 樓宇對講主要設備有哪些（6）聯(lián)網(wǎng)器 </p> <p> 分管理機（棟管理機、總管理機除外）、主機（副機除外）、圍墻機，每臺必須配置一個。它是聯(lián)網(wǎng)的必要設備，有了它，除了可以節(jié)省線材外，還可以減少布線的很多麻煩。 </p> <p> <br /> </p> <p> 樓宇對講主要設備有哪些（7）主呼通道 </p> <p> <p> 指主機發(fā)話輸入端至分機收話輸出端的通道。 </p> <p> <br /> </p> <p> 門口主機－分機通話通道或管理員機－門口主機－住戶通話通道（個別廠家叫做音頻上行通道）。 </p> <p> <br /> </p> 樓宇對講主要設備有哪些（8）應答通道 </p> <p> <p> 分機－門口機通話通道或分機－門口主機－管理員機通話通道（個別廠家叫做音頻下行通道） </p> <p> <br /> </p> <p> 音頻的主呼通道及音頻的應答通道總體上我們稱之為樓宇對講系統(tǒng)的音頻通道，根據(jù)廠家的不同，音頻通道使用的線材數(shù)量有所不同： </p> <p> <br /> </p> <p> 1)將音頻主呼通道及音頻應答通道使用不同的線路傳輸，此時因為音頻的主呼與應答通道不在相同的線路內(nèi)傳輸，從而達到雙工通話的功能。由于分線傳輸，線路增加（共兩條音頻線路，實際上應該是三條音頻線路：應該加上系統(tǒng)地線），但是對于單邊的線路故障比較好 </p> <p> <br /> </p> </p><p> 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－主機的音頻線路問題，還是主機－分機的音頻線路問題（分機能夠聽到主機通話，而主機不能聽到分機通話，或相反）。 </p> <p> <br /> </p> <p> 2)將音頻主呼通道及音頻應答通道使用單一的線路傳輸，通過復用的技術(shù)進行雙工通話。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> 樓宇對講主要設備有哪些（9）視頻通道 </p> <p> <p> 指主機所攝圖像傳輸?shù)椒謾C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行通道的設計。由于樓宇對講系統(tǒng)相當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。 </p> 無錫門禁樓宇對講機</p><p style="text-indent:25px">無錫門禁樓宇對講機</p><p> 1）管理員機的主要功能： </p> <p> <br /> </p> <p> 小區(qū)管理員機必須具備下列一些基本功能： </p> <p> <br /> </p> <p> ?能提供系統(tǒng)設備所需的電源。 </p> <p> <br /> </p> <p> ?監(jiān)視和記錄。 </p> <p> <br /> </p> <p> ?輸出各種遙控信號。 </p> <p> <br /> </p> <p> ?接收各類系統(tǒng)的運行與報警信號。 </p> <p> <br /> </p> <p> ?同時輸入輸出多路視頻信號，并對視頻信號進行切換。 </p> <p> <br /> </p> <p> ?時間、編碼等字符顯示。 </p> <p> <br /> </p> <p> ?內(nèi)外通信聯(lián)絡。 </p> <p> <br /> </p> <p> 2）管理員機的組成： </p> <p> <span style="display:none;"></span> </p> <p> <br /> </p> <p> A、聽筒：主要功能為進行通話； </p> <p> <br /> </p> <p> B、鍵盤：主要功能為進行選通住戶及編程； </p> <p> <p> C、黑白（彩色）顯示屏：主要功能為顯示各單元主機視頻圖像； </p> <p> <br /> </p> <p> D、功能按鍵：主要功能為給各單元主機開鎖、查詢住戶報警信息、編程等； </p> <p> <br /> </p> <p> E、各種接線端子：連接管理員機與各單元主機、電腦之間的接線部分； </p> <p> <br /> </p> <p> F、LCD(LED)顯示屏：管理員機應該能夠顯示時間、住戶房號等字符，通常的管理員機采用LED數(shù)碼管顯示時間及房號等信息。由于LED數(shù)碼管顯示有它的局限性，目前很多廠家出現(xiàn)了使用LCD液晶顯示屏顯示的管理員機。LCD液晶顯示屏可以顯示中文字符，對于管理員進行編程、呼叫等操作非常方便，（在報警聯(lián)網(wǎng)系統(tǒng)中）還可以顯示住戶的警情信息，提升了管理員機的實用性及方便性； </p> <p> <br /> </p> <p> G、內(nèi)部存儲部分：存儲住戶的警情信息是管理員機必須擁有的功能，內(nèi)部存儲部分主要存儲住戶的報警信息（信息包括警情類型、住戶房間號碼、報警時間等 </p> <p> <br /> </p> 無錫門禁樓宇對講機</p><p
