– 使用滿足IP40工業(yè)防護等級的工業(yè)交換機WISE6000B-2GS-8T-WR，配備牢固的光接口實現(xiàn)可靠的以太網(wǎng)連接。在車站內，分布在各處的IP攝像頭通過千兆光纖冗余PoE以太網(wǎng)供電交換機供電。RS232或RS485界面的安檢設備通過WISE3000B產品接入以太網(wǎng)。WISE3000B的千兆端口提供高帶寬干線連接，并使用ZW-Ring技術確保網(wǎng)絡的可靠度。WISE6000B千兆光電信號轉換器將遠端設備通過光纖接入本地，不只是可延長傳輸距離還能防雜訊干擾。WISE9000B機架式交換機將整個系統(tǒng)進行整合，并將數(shù)據(jù)傳送到控制中心。使用完整的正維交通類以太網(wǎng)通訊解決方案系統(tǒng)管理人員可以在控制中心追蹤管理系統(tǒng)報警信息和現(xiàn)場事件信息。</p><p style="text-indent:25px">集線器的發(fā)展產生了一種叫非管理型交換機的設備。它能實現(xiàn)消息從一個端口到另一個端口的路由功能，相對集線器更加智能化。非管理型工業(yè)交換機能自動探測每臺網(wǎng)絡設備的網(wǎng)絡速度。另外，它具有一種稱為"MAC地址表"的功能，能識別和記憶網(wǎng)絡中的設備。換言之，如果端口2收到一條帶有特定識別碼的消息，此后交換機就會將所有具有那種特定識別碼的消息發(fā)送到端口2。這種智能避免了消息，提高了傳輸性能，相對集線器是一次巨大的改進。然而，非管理型交換機不能實現(xiàn)任何形式的通信檢測和冗余配置功能。正維通信的三層工業(yè)以太網(wǎng)交換機系列，專為處理苛刻的工業(yè)應用而設計。</p><div
