摘　　要：由于列车和船舶上的空间有限,互连非屏蔽线缆的空间非常小,导致非屏蔽线缆之间存在严重的串扰问题,其中功率回路对信号回路的串扰会严重影响信号的质量和系统的正常运行,因此有必要估计功率回路中共模和差模电磁干扰对信号回路的影响。为此提出了一种可扩展的级联多端口网络模型,可对线缆间共模和差模串扰进行精准建模,准确估计出功率回路对信号回路的影响。最后,搭建了试验台架进行验证,实验结果验证了该方法的有效性。Due to the limited space in trains and ships,the space for interconnecting unshielded cables is very small,causing serious crosstalk problems between unshielded cables.In particular,the crosstalk of a power loop to a signal loop will seriously affect the signal quality and the system's normal operation.Therefore,it is necessary to estimate the influence of common mode(CM) and differential mode(DM) electromagnetic interference on the signal loop.In this context,a scalable cascaded multi-port network model is proposed,which can accurately model the CM and DM crosstalk between cables and accurately estimate the influence of the power loop on the signal loop.Finally,a test bench was built,and experimental results verified the effectiveness of the proposed method.
