单片机应用系统的软件抗干扰技术

The Software Anti-jamming Techniques of MCU Application Systems

在单片机应用系统中,必须考虑抗干扰的问题。指令冗余、软件陷阱及软件“看门狗”等技术是有效的软件抗干扰措施。干扰后系统复位时,应将重要系统信息从备份中恢复,并将已激活的中断标志清除。

It is necessary to take into account the issue of anti-jamming in the MCU application systems. The techniques, such as instruction redundancy, software trap and software watchdog, etc., are the effective anti-jamming measures. After the system restoration from disturbance, the important system information should be resumed from the backup and the interrupting sign cleaned out.
