摘要
针对单片机测控系统实时性强、干扰因素较多的特点 ,介绍了几种实用的抗干扰措施 ,硬件抗干扰方面包括供电系统设计、电路板合理布局以及输入输出干扰抑制 ,软件方面包括软冗余技术、软件陷阱技术以及“看门狗”技术的几个实例。实践证明 ,硬件和软件二者相互结合、互相补充 ,在实际应用系统中可起到良好的抗干扰作用。
Microcotroller measuring and controlling system has strong real-time characteristics but encounters many interference sources.This paper presents software and hardware anti-interference techniques for it. It can be used as reference for technologists who are studying this subject.
