摘　　要：为满足航空电子设备中机内测试(BIT,Built-in-test)的试验验证需求,设计并实现了基于VxWorks操作系统的1553B总线故障注入设备;总线故障注入设备是1553B总线(MIL_STD_1553B总线的简称)故障注入系统的核心,是实现故障注入任务的关键;结合1553B总线协议和通信特点,基于一般总线故障注入方法,详细分析了适用于该总线的故障注入方法;阐述了总线故障注入系统的结构框架和工作原理,并给出了1553B总线故障注入设备的详细设计方案,包括具体的硬件实现、软件设计和系统的工作流程,最后通过搭建仿真测试环境进行试验,系统对总线上传输的数据进行了有效地故障注入,验证了该故障注入设备功能的正确性和可靠性。To realize the BIT （Built--in--test） experiment for avionics, MIL_ STD_ 1553B bus fault injection device based on Vx Works was designed and implemented. The fault injection device, the key for the fault injecting realization, was the core of the bus fault injection system. Methods for 1553B bus fault injection was proposed by combining the characteristics of 1553B bus. Based on the framework of 1553B bus fault injection system, detailed design for the 1553B bus fault injection equipment had been advanced, including specific hard- ware, software design and system workflow. At last, it＇ s proved that the fault--injection device works correctly and reliably through experiment.
