摘要
从实际应用出发,阐述了单片机控制系统在硬件设计中应该注意到的各种抗干扰问题。主要内容为单片机系统工作时干扰信号的来源、类型及抵抗措施。经过多年的教学、应用和研究,作者认为采用硬件滤波和隔离技术(措施),能有效地滤除系统中的主要干扰。
From the point of application, this paper introduces that the single chip microcomputer control system should pay atten- tion to the variety of anti-interference problem in hardware designing. The main content introduced are the interference signal sources, types and resistance measures for single chip microcomputer system working. After teaching, application and research for many years, it shows that the hardware filtering and isolation technology （measures） can effectively filter the main interference of system. The paper focuses on the discussion from these two aspects so as to bring a reference to the researchers in this field.
