摘要：

分析1553B总线组网拓扑，设计一种结合并行总线拓扑和层次总线拓扑的混合总线拓扑结构，在此基础上给出一个通信协议栈。针对传输层异步通信，设计基于传输矢量字方式代码的控制流程、报文传输流程、矢量字格式以及报文格式。在网络层上设计数据分组格式，从而实现基于LabVIEW的协议测试软件。

Abstract:

The bus topology of 1553B is analyzed. A new topology of composite bus topology based on parallel bus topology and hierarchical bus topology is designed, and the communication protocol stack is put forward. The transport layer based on transmit vector word is given. The process of message transfer and the structure of vector word and message are also introduced, as well as the data clustering of network layer. It realizes the testing software based on LabVIEW.

Key words: 1553B bus, topology, transport layer, network layer
