单片机应用系统的抗干扰具体可分为软件和硬件两方面，其中，软件抗干扰

以其设计灵活、节省硬件资源、降低成本等优势越来越得到广泛采用。软件抗干

扰技术主要有“指令冗余技术”、“软件陷阱技术”、“软件看门狗技术”、“数

字滤波技术”等。本文就软件陷阱技术对单片机应用系统抗干扰的原理与具体实

现方法进行探讨和研究，给出实现软件陷阱技术的两种形式，并将该技术成功地

使用在多个实际的单片机应用系统中，保证系统的可靠运行。-Application System of specific anti-jamming software and hardware can be divided into two aspects, one, software, anti-jamming

Its flexible design, save hardware and reduce the cost advantage of more and more widely adopted. Software Anti-dried

Interference technique as "command redundant technology", "software trap technology", "Software Watchdog Technology", "number of

Word filter technology ", etc.. In this paper, the software trap technology Application System Interference Principle and the specific reality

Explore and study methods are given to achieve the two forms of the software trap technology and the technology successfully

Microcontroller using a number of practical applications, ensuring system reliability.
