The Design of 1553B Bus Fault Injection Device and its Implementation for BIT Verification

To verify the Built-in-test (BIT) in the avionics system, a MIL_STD_1553B (1553B for short) bus fault injection device under VxWorks was designed and implemented. The fault injection device was the core of the bus fault injection system. A method for 1553B bus fault injection was proposed by analyzing the characteristics of 1553B message transmission. On the basis of the research on the framework of 1553B bus fault injection system, the detailed configuration of the 1553B bus fault injection device had been described, including the implementation on hardware and the design of software. At last, it´s proved that the fault-injection device can inject faults into the target system correctly and reliably by simulation test.
