在網絡發達的今天，交換機被許多需要使用網絡的朋友使用，可以實現一個網絡多臺電腦公用。但是什么是工業以太網交換機，很慣性的思維就是工業用的交換機，但是具體工業以太網交換機性能特點有什么呢大家就可能會疑惑了。工業以太網交換機主要是應用于復雜的工業環境中的實時以太網數據傳輸，利用了交換機技術以及以太網傳輸的技術，特別是以太網傳輸的速度。下面小編就來和大家分享一下工業以太網交換機性能特點，以及它于普通交換機的區別。

　　首先是工業以太網交換機的簡介，由于它是用于復雜而且苛刻的工業環境中(高溫、實時性要求高、傳輸速率要求很快，相應需要快速等)，在以太網在設計時，普通的交換機都是采用載波偵聽多路復用沖突檢測(CSMA/CD機制)，工業應用時可靠性低;而工業以太網交換機則是采用存儲轉換交換方式，利用以太網的通信速度，內置智能報警設計監控網絡運行狀況，在惡劣危險的工業環境也保證以太網可靠穩定的運行。

　　我們在說一下工業以太網交換機的特點，高性能以太網交換機技術來保證通信速度，采用的是IEEE802.3/802.3d/802.3u/802.3x接口標準和存儲轉換交換方式的輸出方式，具有抑制廣播風暴功能、端口鏈路告警功能;電源發生故障時故障信息用繼電器輸出進行報警，冗余24伏直流電源輸入，工作溫度在-40度～75度工作溫度，高強度外殼，防護等級達到IP30，工業級標準設計，10Base-T/100Base-TX自適應的以太網接口，MDI/MDI-X，全雙工/半雙工自適應方式;安裝方便，傳輸距離較大(相對而言)，為了不受磁電的影響，具有電磁隔離和電磁保護的功能，它的這些特性決定工業以太網交換機可以用于工業控制自動化，道路交通控制自動化，樓宇自動控制系統，礦井自動控制系統，油田控制自動化，水電站控制自動化，電力系統控制自動化，機房監控系統等工業的應用。

　　工業以太網交換機

　　工業以太網交換機與普通交換機的區別，主要體現在功能和性能上。

　　工業以太網交換機在工業級設計一般在設計上滿足：工業寬溫設計，4級電磁兼容設計，冗余交直流電源輸入，另外PCB板一般做“三防”處理。工業現場的環境比普通環境都要惡劣，至少在震動，濕氣，溫度上都要比普通環境惡劣，普通交換機在設計上沒有抵御在工業環境中出現的各種情況的能力，普通交換機不能長時間工作在這種惡劣環境下，經常容易出現故障，更使維護成本上升，一般不建議在工業環境中使用商業交換機，為了能使交換機在這種惡劣環境中使用，故生產出能適應這種環境的交換機，工業級別的交換機的可靠性有電源故障，端口中斷，可由繼電器輸出報警，冗余雙直流電源輸入，主動式電路保護，過壓、欠壓自動斷路保護。

　　(1)功能：工業以太網交換機與工業網絡通訊更加接近，比如各種現場總線的互通互聯、設備的冗余以及設備要求的實時性。

　　(2)性能：主要體現在適用外界環境的參數不一樣，工業環境除了特別惡劣的環境之外，還要求有EMI電磁兼容、溫度、濕度、防塵等，特別是溫度對工業網絡設備的影響是zui廣泛的。

　　工業以太網交換機使用的注意事項：

　　(1)不要將設備放置在接近水源或者潮濕的地方;

　　(2)電源電纜上不要放任何的東西，將其放在碰不到的地方;

　　(3)為了避免火災，不要將電纜打結或者包住;

　　(4)電源接頭以及其他設備連接件需要連接牢固，并經常檢查線路的牢固性;

　　(5)保持光纖插座和插頭的清潔，設備工作時，不要直視光纖的斷面;

　　(6)注意設備清潔，必要時可以用棉布擦拭;

　　(7)設備出現故障時，為了安全起見不要自己維修。
