单片机测控系统抗干扰措施

Anti-interference Measures of SCM Measurement and Control System

单片机测控系统的工作环境往往是复杂、恶劣的 ,影响测控系统可靠、安全运行的主要原因是来自系统内部和外部的各种电气干扰。因此 ,抗干扰设计是单片机测控系统不可忽视的重要内容 ,常用的抗干扰技术主要有硬件抗干扰和软件抗干扰。硬件抗干扰主要有供电系统抗干扰 ,过程通道抗干扰。软件抗干扰有数字滤波技术、输入口信号重复检测。

The reason why the interference arises in SCM measurement and control system, the form and the result are expounded here, especially the methods and measures of anti-interference. The paper primarily discusses anti-interference measures of primarily SCM measurement and control system from the two aspects of hardware and software.
