在樓宇對(duì)講系統(tǒng)中使用的門禁系統(tǒng)一般采用感應(yīng)式ID卡及感應(yīng)式IC卡。小區(qū)一卡通一般采用感應(yīng)式IC卡來完成（因?yàn)镮C卡有比較強(qiáng)大的存儲(chǔ)功能，可將很多信息存儲(chǔ)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(yīng)距離、可靠性、數(shù)據(jù)運(yùn)算能力、抗干擾能力等均比MIFARE技術(shù)卡強(qiáng)，但由于價(jià)格的原因，MIFARE技術(shù)卡在實(shí)際中大量的應(yīng)用。 </p> <p> <br /> </p> <p> 在樓宇對(duì)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(jī)上，門口主機(jī)必須有一塊專門進(jìn)行讀卡的部分。感應(yīng)卡一般采用射頻技術(shù)，蘇州安防樓宇對(duì)講維修，蘇州安防樓宇對(duì)講維修，蘇州安防樓宇對(duì)講維修，金屬的物體對(duì)于感應(yīng)卡有屏蔽作用，從而影響卡的感應(yīng)舉例。門口主機(jī)的感應(yīng)卡部分必須采用非金屬質(zhì)地，以降低對(duì)門禁感應(yīng)卡的屏蔽。

B、底盒：主機(jī)的安裝暗埋（明裝）盒，主要通過底盒的固定（一般有埋墻安裝、鑲門安裝等），主機(jī)的面板再固定在底盒上。主機(jī)底盒的使用材質(zhì)根據(jù)不同廠家有金屬底盒以及塑料底盒兩種，但主要的原則是堅(jiān)固，避免因?yàn)榘笛b而產(chǎn)生的擠壓變形。 </p> <p> <br /> </p> <p> C、操作部分：可操作是主機(jī)的**基本要求，操作部分均在主機(jī)的面板上，通常由操作按鍵部分及操作顯示部分組成。操作按鍵（直按式的按鍵及數(shù)字式的數(shù)字鍵盤）按照質(zhì)地一般有金屬按鍵及塑料按鍵兩種，金屬按鍵堅(jiān)固耐用（主機(jī)的按鍵是使用頻率比較高的部分，堅(jiān)固耐用應(yīng)該是首先考慮方面，目前市場上出現(xiàn)的使用銀行柜員機(jī)按鍵，將單鍵壽命到百萬次以上便是例子），但金屬按鍵的缺點(diǎn)主要是夜間顯示（有些廠家的產(chǎn)品基本已經(jīng)解決夜間顯示金屬按鍵的問題）。塑料按鍵的透光能力比較強(qiáng)，但缺點(diǎn)是耐用性不強(qiáng)，按鍵容易老化及損壞。蘇州安防樓宇對(duì)講維修</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州安防樓宇對(duì)講維修,樓宇對(duì)講"

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(duì)于雙線傳輸減少一根。 </p> <p> <br /> </p> <p> 樓宇對(duì)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(duì)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(jì)。由于樓宇對(duì)講系統(tǒng)相當(dāng)于一點(diǎn)對(duì)多點(diǎn)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(duì)講系統(tǒng)中，視頻分配器是系統(tǒng)視頻通道中一個(gè)必不可少的器件。視頻分配器的功能主要是對(duì)一個(gè)視頻信號(hào)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。 </p> </p><p> 樓宇對(duì)講主要設(shè)備有哪些（4）解碼器 </p> <p> <p> 解碼器為安裝在樓層主干線與分機(jī)間進(jìn)行解碼及隔離保護(hù)的設(shè)備。 </p> <p> <br /> </p> <p> 主要使用在數(shù)字式系統(tǒng)中，目前國內(nèi)樓宇對(duì)講廠家中有兩種數(shù)字式系統(tǒng)的解碼方式：分機(jī)內(nèi)解碼方式、外置解碼器方式。以下就兩種不同的類型解碼方式的產(chǎn)品 </p> <p> <br /> </p> <p> 從解碼方式、起源等方面進(jìn)行簡單講解： </p> <p> <br /> </p> <p> 1)解碼：相比于傳統(tǒng)的模擬系統(tǒng)，數(shù)字式系統(tǒng)容量更大、功能更強(qiáng)。目前數(shù)字式樓宇對(duì)講系統(tǒng)將每個(gè)住戶定義為一個(gè)可尋的地址，主機(jī)在輸入這個(gè)可尋的地址后，通過解碼器等相關(guān)的器件對(duì)相應(yīng)的住戶進(jìn)行選通，然后進(jìn)行振鈴、通話、開鎖等功能。 </p> <p> <br /> </p> <p> 2)分機(jī)內(nèi)解碼：將解碼部分放置在分機(jī)內(nèi)部 </p> <p> <br /> </p> <p> 3)外置解碼器：將解碼部分集中在一臺(tái)解碼器中（解碼器一般為四戶型或八戶型），解碼器放置在大樓內(nèi)弱電井中。 </p> </p><p> 6)內(nèi)解碼：內(nèi)解碼系統(tǒng)由于將解碼器放置在分機(jī)內(nèi)部，理論上可以將各個(gè)分機(jī)串聯(lián)在一條數(shù)據(jù)通道上，接線十分方便，但在實(shí)際應(yīng)用中內(nèi)置解碼分機(jī)系統(tǒng)出現(xiàn)了一些非常難處理的情況，如：一戶出現(xiàn)問題，將影響到一條線上的所有住戶，而且問題很難排查（因?yàn)槭莾?nèi)解碼，必須進(jìn)入住戶室內(nèi)對(duì)分機(jī)及線路進(jìn)行檢查，而且接線錯(cuò)誤等問題也可以造成比較巨大的影響）。內(nèi)解碼系統(tǒng)的廠家自98年以后開始增加短路保護(hù)器（根據(jù)廠家不同也有叫隔離器），具體方式就是將原先串聯(lián)在一起的各個(gè)住戶分機(jī)通過短路保護(hù)器進(jìn)行隔離。增加短路保護(hù)器后總體的布線結(jié)構(gòu)與外置解碼器系統(tǒng)相同（主機(jī)將各個(gè)短路保護(hù)器串聯(lián)，再從短路保護(hù)器向各個(gè)住戶分機(jī)進(jìn)行分支，這樣的布線方式我們稱之為樓內(nèi)總線布線方式）。一些內(nèi)解碼系統(tǒng)的廠家在短路保護(hù)器上增加了如故障指示等外置解碼器所擁有的功能，使樓宇對(duì)講系統(tǒng)的布線方式逐漸的趨于統(tǒng)一。 </p> <p> <br /> </p> <p> 通過樓內(nèi)總線方式進(jìn)行的單棟住宅的樓宇對(duì)講系統(tǒng)布線有更好的維護(hù)性能，系統(tǒng)在進(jìn)入使用階段后，對(duì)于日常的維護(hù)工作提供很多幫助。蘇州安防樓宇對(duì)講維修</p><p style="text-indent:25px">蘇州安防樓宇對(duì)講維修</p><p> 網(wǎng)門禁系統(tǒng): </p> <p> <br /> </p> <p> 隨著樓宇對(duì)講系統(tǒng)在各個(gè)住宅小區(qū)的廣泛應(yīng)用，很多廠家將門禁系統(tǒng)集成在樓宇對(duì)講系統(tǒng)中的門口主機(jī)上，下面就簡單講解一下門禁系統(tǒng)的功能及應(yīng)用：門禁系統(tǒng)有不聯(lián)網(wǎng)和聯(lián)網(wǎng)系統(tǒng)兩大類。由于在樓宇對(duì)講系統(tǒng)中使用，我們就主要介紹聯(lián)網(wǎng)門禁系統(tǒng)。 </p> <p> <br /> </p> <p> 聯(lián)網(wǎng)門禁系統(tǒng)一般由控制設(shè)備（含控制軟件、網(wǎng)絡(luò)控制器及門禁控制器）和前端設(shè)備（含讀卡機(jī)、電控鎖、門磁及出門按鈕）兩大部分組成。樓宇對(duì)講系統(tǒng)中，將網(wǎng)絡(luò)控制器、門禁控制器、讀卡器集成在門口主機(jī)中，通過樓宇對(duì)講系統(tǒng)的聯(lián)網(wǎng)線路與管理中心中的電腦組成網(wǎng)絡(luò)，信號(hào)的傳輸使用樓宇對(duì)講系統(tǒng)的信號(hào)通道（采用RS485通信協(xié)議）。蘇州安防樓宇對(duì)講維修</p><p
