摘　　要：单片机系统在各个领域中都得到了广泛、深入的应用,然而由于单片机工作环境常有各种干扰,影响单片机应用系统的控制准确性及测量数据的精度,因此提高控制系统的抗干扰性至关重要。主要论述了单片机软件抗干扰的方法,具体阐述防止程序因干扰失控的软件设计方法及采样数据的数字滤波方法。Single - chip computer is applied wider in more and more fields. Meanwhile, various interference in single - chip computer application environment infect control accuracy and survey precision of single - chip computer application system, so it is very important to improve the anti - interference ability of single - chip. This paper discusses the way of software anti - interference, expatiates method of preventing program out of control and digital filtering of sampled data.
