增强型1553总线协议分析与接口卡设计

Enhanced Bit Rate 1553 Bus Protocol Analysis and Interface Board Design

在已有成熟技术的传统航空总线基础上,为寻求数据传输速率的突破,通过对增强型1553(EBR-1553)数据总线的描述,比较它与传统1553B总线的区别,分析EBR-1553总线的通信系统体系结构,介绍传输协议中的字格式和消息格式。提出一种基于PCI总线的增强型1553总线接口卡的实现方案,描述设计中的关键点,对EBR-1553总线的研究和使用具有一定的借鉴意义。

As to look for a breakthrough for data transfer rate based on a mature traditional air bus technology, through the description of the Enhanced Bit Rate 1553（EBR-1553）, compared with the traditional 1553B bus, the communication system architecture of EBR-1553 bus is analyzed, and the word format and message format of its transfer protocol are introduced. A hardware solution of the enhanced bit rate 1553 bus interface board based on PCI bus is raised, some key circuits of the design are described, and reference for future research and use of EBR-1553 bus are provided.
