摘　　要：传统的故障模拟系统在卫星测试中设备通用性差、模拟信号类型单一等多方面不足,已不能满足航天器批产化测试模式的需求。针对现有平台存在的不足,结合1553B总线协议和通信特点,对总线故障注入关键技术进行深入研究,提出一种利用星载1553B总线为故障注入介质,以数据仿真替代真实模拟故障输入激励的1553B总线故障注入系统。应用结果表明,故障注入测试方法可以实现预期的故障目标,提高了设备的通用性及航天器测试效率,降低了地面设备研制成本。Such situation has higher requirements for independent fault processing ability of ground verification.In satellite tests,traditional fault simulation system cannot meet the requirement of testing the whole spacecraft in batch due to the weakness such as lacking in equipment universality,monotonous type of analog signals,etc. Targeting at the weakness of existing platform,a 1553 B bus fault injection system is proposed,which takes satellite-borne 1553 B bus as fault injection medium and replaces real simulation failure input excitation with data simulation. The system improves equipment universality and testing efficiency,and reduces the costs for developing ground equipment.
