现有的总线故障注入系统多针对某一种总线进行故障注入,不能满足对多类型总线系统动态、实时的模拟测试要求。为了能够仿真武器系统多种总线在多种故障模式下的响应,搭建了针对多类型总线的电气故障注入系统,并描述了该系统在多种总线的武器系统中应用的优势。通过CAN总线协议层、RS422总线电气层同时进行的故障注入试验,验证了该故障注入系统在多类总线、多种故障模式下同时进行故障模拟的有效性。

The existing bus fault injection system mostly inject faults for single bus, it cannot satisfy the dynamic and real-time simulation test requirements of the electrical fault in the multi-type bus system. In order to simulate the response of multiple buses in multiple fault modes, an electrical fault injection system for multi-type bus is built, and describe the advantages of the fault injection system in the weapon system with multiple buses. Through simultaneous fault injection test of the protocol layer of CAN and the electrical layer of RS422, the validity of the fault injection system in multi-class bus and multiple fault modes is verified.
