【摘要】 绞线式列车总线(WTB)是IEC制订的用于列车级车载数据通信的总线标准。本文提出了一种WTB节点设计的框架方案,并设计实现了具备WTB基本功能的原型节点。该原型节点的设计重点放在WTB的核心部分——WTB链路层的软硬件实现,实现了WTB的基本功能,并为进一步开发实用的WTB技术和产品作准备。更多还原

【Abstract】 Wired Train Bus is a specification for train-level communication proposed by IEC. A framework of full function WTB node is proposed in this paper, and a prototype of WTB node is also implemented according to the framework. The link layer of WTB specification, which is the core of WTB, is emphasized in the prototype, and essential function of WTB is implemented.更多还原
