摘要
为了验证MCU控制系统故障控制措施的有效性,采用软件故障模拟设置和硬件故障注入相结合的方法建立了故障控制措施的验证平台。采用程序调试软件改变控制器内部器件的数据来模拟软件或硬件故障,采用硬件故障注入电路来模拟控制器外围电路故障,即开路、短路及电平变化。该平台已用于IEC60335/IEC60730/UL1998/CSA22.2.08标准的软件故障控制措施评估,针对一个具体案例的故障控制措施进行了验证试验,结果表明,该验证平台运行稳定可靠,具有很好的实用性。
To verify the validity of fault control measures, a verification platform with software fault injection and hardware fault injection is developed to conduct fault diagnosis measures for MCU control system. For the faults occurring in the internal units of a controller, program debugger is employed to simulate software or hardware faults by varying the data; for the faults occurring in peripheral circuits, a circuit of fault-settings is employed to simulate hardware faults, i. e. , open-/short-circuit and electrical level variation. This verification platform is applied to evaluate software measures to control the faults/ errors in accordance with IEC60335/IEC60730/UL1998/CSA22. ：2.08, a case of induction cooker is presented shows how it works. The experimental results show that the verification platform runs stably and accurately, and has a big value in practice.
