单片机应用系统的软件抗干扰措施

The Software Anti-interference Measure of Single Chip Computer Application System

单片机应用系统工作环境恶劣,其抗干扰性能的好坏对自身的稳定运行至关重要。本文分析了软件抗干扰的特点,并针对干扰对系统软件的影响,给出了相应的软件抗干扰措施,其中包括数字滤波,软件容错,数据冗余,软件狗,指令复执,多重动作等。实践证明,这些软件抗干扰措施对提高单片机应用系统的稳定运行有很大帮助。

The single chip computer application system runs m interferential surroundings.The anti-interference capability is very important for its stabilization.The article analyzes the characteristics of software anti-interference and interoduces some effective software anti-interference measures according to the interfernce influences,such as digital wave filtering,error diagnosis,software watchdog command redundance and so on.It is proved in practices that these software anti-interference measures are hlpful for the stabilization of the single chip computer application system.
