非均匀分布传输线的频率响应及其在铁路安全监测中的应用
Frequency Response of Transmission Lines with Unevenly Distributed Properties with Application to Railway Safety Monitoring
摘要：
本文提出了一种快速有效地计算沿输电线路的电压和电流的方法，这可能是“损坏”，即其电气特性可以不均匀分布。该方法通过自相似电路网络来近似传输线，并利用我们以前关于该类网络的频率响应的工作。主要动机来自于铁路轨道电路系统的研究，其中经常使用传输线模型。然而，与真实的传输线路相比，铁路轨道电路更容易由于其规模和环境的不确定性而被损坏;此外，由于训练占据轨道的一段而引起的电路特性的变化作为确保安全的手段也是非常感兴趣的。因此，准确、快速地模拟轨道电路的损伤状态是十分必要的，也是今后轨道电路健康监测研究的重要内容。
英文摘要：
This paper proposes a method to quickly and efficiently compute the voltage and current along a transmission line which can be "damaged"; that is its electrical properties can be unevenly distributed. The method approximates a transmission line by a self-similar circuit network and leverages our previous work regarding the frequency response for that class of networks. The main motivation arises from the research for railway track circuit systems where transmission line models are often employed. However, in contrast to real transmission lines, railway track circuits are more likely to be damaged due to its scale and environmental uncertainties; furthermore, changes in circuit properties due to a train occupying a segment of the track also is of great interest as a means to ensure safety. As a result, an accurate and quick simulation of damaged track circuits is necessary and can contribute to the corresponding health monitoring research area in the future.
