客车行车安全监测诊断系统 该系统对危害旅客行车安全的因素进行实时监测诊断、记录和存储，集中显示和报警，运行中对影响行车安全的严重故障特别提示，指导乘务员采取紧急措施保障运行安全，停车时通过地面下载数据指导维修，对车辆进行质量动态控制。运行中，车载监测诊断系统通过无线通讯装置向地面监控终端报告列车运行情况，列车到站时，通过无线局域网或移动存储器将记录数据下载到地面数据库和专家系统，实现了信息化的客车实时安全监控和运用状态的动态检修和管理。 加工车间自动化 使用研华工业以太网交换机EKI-7656C和EKI-7657C组成冗余环网架构 太阳能热电控制系统 采用研华无线AP EKI-6311G与无线串口服务器EKI-1351两种设备。由于现场有100个PLC设备，且每台PLC均需要采用无线方式传输至上位机。由于现场PLC与中控室距离较远，且无线节点较多，为保障无线网络传输的可靠，因此我们推荐每10台PLC透过1台无线AP连接，即总共需10台无线AP。无线AP间采用WDS (Wireless Distribution System无线分布式系统) 技术，让无线网络的多台无线AP设备灵活的桥接，方便的把100台PLC的数据透过100个EKI-1351传输至无线AP，最终再上传至中控室的上位机。 Thank you * * * * * * * * * * * * This structure shows the newest and much advanced reliable network for power substation. There are 2 outstanding features I want to introduce to you here: 1,In order to distribute network danger, all end devices are divided into 2 large groups. For large scale substation building, it is very necessary. In each group, Each device is connected to two rings at the same time for redundancy. From this topology, you can see that C1 AND C2 are core switches for station computers. C1 is the backup of c2. each of them can acquire the data from group A through a1 or a2 .a1 is also the backup of a2. In the same way, each of them can acquire the data from group b through b1 or b2 .b1 is also the backup of b2. 2,it should support single ring recovery and the recover time should be controlled within 100 miliseconds. As I know, most of industrial switch usually can only support all the rings recover at the same time, but it is not reasonable. Till now advantech switch is the only one who can support these requirements among industrial switch manufacturers. 双路DC电源输入 12 ～48 VDC, 接线端子模块 故障时由继电器输出报警 (-) (+) (-) (+) DC 电源正常极性状态 (+) (-) (+) (-) DC电源反接保护功能， 在电源极性反接时设备仍能正常工作 电源极性反接保护设计 二、保障数据传输的确定性 交换技术 1000Mbps高速传输 全双工工作模式 QoS流量优先级 High VOIP Middle Video Low E-mail Lowest Data High VOIP Middle Video Low E-mail Lowest Data 4 8 2 1 三、LFP（Link Fault Pa
