This paper makes brief discussion on the mechanism of the electromagnetic field screening by means of single-point and two-point grounding of the shielded layer of cable and proposes some problems that have to be paid attention to in two-point grounding. 该文浅议屏蔽电缆屏蔽层一点、两点接地对电磁场屏蔽的机理,并提出了两点接地时应注意的问题。
Research on Single-Point Grounding Technology in the Mixed-signal PCB Design 混合信号PCB设计中单点接地技术的研究
It analyses the principle of electromagnetic shielding and some ways of grounding: single-point grounding, Multi-point grounding, mixed grounding and suspension grounding. 对电磁屏蔽的原理及应用和接地的几种方式:单点接地、多点接地、混合接地和悬浮接地进行了分析。
In particular, the establishment of a data analysis server realizes the automatic processing of experimental data; it adopts single-point grounding in data acquisition and installs electromagnetic shielding network, and thus greatly reduces the impact of electromagnetic interference towards data acquisition. 特别是建立了数据分析服务器,实现实验数据的自动处理;在数据采集端采用单点接地及安装电磁屏蔽网,极大地减小了电磁干扰对数据采集的影响。
