摘要
微机保护装置工作环境恶劣,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微机保护装置的稳定运行有很大的帮助。
Microcomputer safe -device runs in interferential surrounding s,the anti-interference capability is therefore important for its stabilization.This paper analyzes the characteristics of software anti-interference and intro-duces some effective software anti-interference measures according to the interference influences,such as dig ital wave filtering ,error diag nosis,software watchdog ,command redundance and so on.It is proved in prac-tices that these software anti-interference measures are helpful for the stabilization of the microcomputer safe-device.
