摘要
针对单片机应用系统实时性强,干扰因素较多的特点,本文介绍了几种实用的抗干扰措施,在硬件抗干扰方面阐述了供电系统的设计、电路板的合理布局以及输入输入干扰的抑制,软件方面给出了软冗余技术、软件陷阱技术以及“看门狗”技术的几个实例。
According to the special characteristics of the Microcontroller measuring and controlling system -- real-time and interference factor, we present anti-interference techniques. On the hardware side, we discuss the design of power system, reasonable layout of the circuit board and restraining IO interference. On the software side, we provide practical techniques, such as the soft redundancy techniques, soft trap and watching dog.
