工业恶劣环境中单片机在数据采集中的抗干扰设计

Prevention of Disturbance in Process Channel of Monolithic System to Deal with Problem of Jamming in Chip Microprocessor System in Severe Loditions

单片机应用系统的工作环境通常是十分复杂的,如何保证系统的高可靠运行,是单片机系统设计的基本要求.本文针对恶劣环境下单片机系统的干扰问题,阐明了如何利用软硬件抗干扰设计问题.对常用滤波法进行了详细介绍并举出了实例.

The working condition of monolithic application system is usually quit complicated. How to ensure it to run unfailingly is the base demand in the design of monolithic system. To deal with the problem of jamming in chip microprocessor system in severe loditions, the basic princple and algorithms of software anti jamming are presented in this paper. Especially the commonly-used and effective digital filtering are introduced in detail and a practical example is presented.
