從設(shè)備冗余性方面考慮，該項(xiàng)目采用環(huán)型網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)，采用恒啟電子HES8M-2SSC-VLW交換機(jī)作為環(huán)網(wǎng)主干設(shè)備，同時(shí)開啟環(huán)網(wǎng)協(xié)議保證網(wǎng)絡(luò)的穩(wěn)定性。

　　該款交換機(jī)能夠提供6個(gè)百兆電口，2個(gè)SC百兆光口（單模雙纖，20公里），是實(shí)現(xiàn)遠(yuǎn)距離傳輸?shù)?設(shè)備。全金屬機(jī)殼以及工業(yè)化無風(fēng)扇設(shè)計(jì)使得該設(shè)備能夠工作在-40到75°C的溫度環(huán)境中。該項(xiàng)目中在每個(gè)水利站點(diǎn)放置一臺該型號交換機(jī)，電口上聯(lián)恒啟工業(yè)4G路由器，下聯(lián)MESR Modbus網(wǎng)關(guān)，剩余的4個(gè)電口可以供現(xiàn)場的IPC等終端設(shè)備使用；2個(gè)光口通過單模光纖分別連接其他站點(diǎn)的交換機(jī)，同時(shí)在光口上開啟恒啟RingOn冗余環(huán)網(wǎng)協(xié)議，實(shí)現(xiàn)毫秒級別（≤15ms）的故障切換。

3.34G蜂窩VPN專網(wǎng)

　　依托運(yùn)營商的4G網(wǎng)絡(luò)，可以在主控端的路由器（防火墻）以及各個(gè)站點(diǎn)的4G路由器之間建立VPN隧道，實(shí)現(xiàn)專網(wǎng)的數(shù)據(jù)傳輸。

　　該項(xiàng)目中采用USG防火墻作為VPN服務(wù)端，WAN口分配靜態(tài)公有IP地址，LAN口連接后臺的服務(wù)器區(qū)；恒啟工業(yè)4G路由器HFE3A27作為VPN接入設(shè)備，放置在各個(gè)水利信息點(diǎn)。4G路由器和防火墻之間建立L2TP VPN隧道，通過VPN隧道，主控端的管理軟件（安裝在后臺服務(wù)器上）能夠通過Internet從各個(gè)站點(diǎn)的總線監(jiān)控傳感設(shè)備中獲取采集數(shù)據(jù)，實(shí)現(xiàn)跨Internet的兩地LAN局域網(wǎng)的互聯(lián)互通。
