摘要:
为了满足列车通信网络中过程数据与消息数据传输的需要，在可扩展处理平台上，设计了一种基于列车实时数据协议（TRDP）的以太网网卡，并在此基础上提出一种片间总线接口方法，实现了对过程数据和消息数据的实时交互,解决了传统片间总线速率低的问题；同时利用串并联端接电阻，从硬件上改善了高速片间总线的信号完整性，保证了高速模式下过程数据与消息数据的实时交互；在所搭建的研究测试平台上，实现了TRDP对过程数据的高速传输。
Abstracts:
In order to meet the needs of the process data and message data transmission in train communication network, an Ethernet network card based on TRDP architecture is designed on the extensive processing platform. On this basis, a new inter chip bus interface technology is proposed, it realizes the real-time interaction between process data and message data, solves the low transmission rate problems of the traditional inter chip bus technology. By using serial and parallel connection end resistance, the reflection problem of signal integrity under high-speed inter chip bus is solved, and the real-time transmission of TRDP process data under high-speed mode is realized; by building a test platform, the high-speed communication transmission technology based on TRDP is achieved.
