摘要
单片机系统的电磁兼容性决定了其工作的稳定性。电磁兼容设计涉及单片机系统设计的所有环节。围绕单片机系统PCB板的电磁兼容设计,常规应包括元器件的选择和布局、布线、地线系统、滤波和屏蔽的设计等等。经研究与实践证明,在充分考虑上述设计要求的前提下,对单片机系统进行模块化设计和数据总线滤波设计可有效地提高系统的电磁兼容能力。
In the SCM （Single Chip Micro-control） system, EMC affects its working stability. All segments of the SCM system design are relation to the EMC design. According to the PCB board design of the SCM system, general it includes the components＇ selection and layout, assigning wires, ground wires design, wave filtering and shielding design, etc, Researchers and experiments show that under some design requirements referred in this paper, the module design and data bus filtering design can improve the EMC capacity of the SCM system.
