| 摘 要： | 从脉冲信号对屏蔽双绞线的容性耦合和感性耦合两个方面进行分析，采用实验脉冲信号发生器作为干扰源对基于非屏蔽双绞线和不同接地方式屏蔽双绞线的CAN总线通信系统进行实验．实验结果表明：非屏蔽双绞线和屏蔽层不接地屏蔽双绞线电磁脉冲耦合效果基本相同，屏蔽层双端接地可以抗脉冲信号的容性耦合和感性耦合．

| Abstract: | The paper analyzed the captive and inductive coupling of pulse signal on shielded twis- ted-pair,and tested the communication system based on CAN which was connected through twis- ted-pair and shielded twisted-pair by a pulse signal generator. The results show that the electro- magnetic pulse coupling effect on twisted-pair and shielded twisted-pair whose shield is not grounded are basically the same and the shield doubly terminated can weaken the capacitive and inductive coupling. |
