摘　　要：针对单片机系统受到干扰后出现的非正常运行现象,通常采用硬件或软件使系统复位的方法保证系统继续运行.而在实际应用中,必须保证复位后运行和记录的数据正确可靠.为此,本文提出了防止此现象发生和保证系统无扰动复位运行的硬件和软件容错方法,实际应用表明:可解决系统死机、跑飞等问题.Aiming at the unpredictably abnormal operating phenomenon which occurs as a result of various disturbances when the monolith machine is in operation, the hardware or software methods which can make the system reset are taken to keep on nmning. However, it must be assured that the running and recorded data are correct and reliable in the practical application. For the purpose, the paper proposes the fault tolerance method of hardware and software to prevent the phenomenon and make the system reset and run without disturbances. It has been testified that the method is very satisfying in the application.
