摘　　要：TRDP以太网卡是新型以太网控车网络系统的关键设备,各子系统通过TRDP以太网卡可接入整车网络,实现数据的实时交互。文中从分析TRDP以太网卡的功能和需求出发,介绍了研制TRDP以太网卡硬件系统和软件系统的设计方案。通过以太网一致性测试和功能测试结果验证了研制的TRDP以太网卡的性能和设计方案。The TRDP Ethernet communication card, which is capable of real-time interaction of train control information, is a key device of the new-type Ethernet-based train communication network. Based on the important functions and requirements of TRDP Ethernet communication card, the structure and scheme of the hardware and software are proposed. The design scheme and functions of TRDP Ethernet communication card developed by our team are validated by the Ethernet conformance testing and functional testing.
