摘要
我们设计的无线体温监测系统由于在开发设计时产品的设计、布局出现了问题,产生了电磁干扰(EMI),造成了电磁兼容性(EMC)问题。我们基于系统电路原理图,从PCB布局布线设计等方面优化晶振和时钟信号匹配电路,并介绍如何解决EMI干扰,避免EMC问题。
As Our wireless temperature monitoring system make some defect in product design and layout designhas, it creates electromagnetic interference(EMI) and causing electromagnetic compatibility(EMC) problems. Based on the system circuit schematic diagram, we optimize the crystal oscillator and clock signal matching circuit from the aspects of PCB layout and wiring design, and introduce how to solve EMI interference and avoid EMC problems.
