摘　　要：针对1553B总线仿真测试融入到分布式测试系统中的需求,提出了一种基于ARM和Linux的仿真测试前端系统方案。该系统的硬件部分主要用来完成对1553B协议芯片的模式配置,软件基于嵌入式Linux编程,完成对1553B消息和测试命令的处理,结合1553B通信协议对其测试和分析,结果表明,该分布式前端系统能够严格按照1553B协议发送消息,时间误差精度小于1μs。In order to satisfy the requirement of the 1553B bus simulation test front-end system into distributed simulation testing platform, the structure of distributed system based on ARM and Linux is adopted in this paper. The hardware system is used to configure 1553B protocol chip. The software system adopts embedded Linux system as development environment. The1553B bus simulation test front-end system can process test instructions and 1553B messages. The performance of the 1553B bus simulation test front-end system is tested and analyzed according to the 1553B communication protocol severely. It shows that the distributed system can achieve the 1553B communication protocol design requirement, the accuracy of time error is less than 1μs.
