摘要
当前信号远程传输方法,没有实现传输通道能量与传输通道信号并行,导致信号远程传输失真性较高。为提高地震信号远程传输的效率,提出新的高速铁路地震监测系统中信号远程传输技术。采用信号传输通道中地震信号能量的并行方法,通过信号传输通道中信号并行传输结构,实现信号在传输通道中双向传输;利用高频阻波电路阻断信号的高频载波通过谐振补偿电容,确保传输通道能量传输不受干扰;根据通道能量传输结构与信号传输过程,实现传输通道能量、信号并行,完成高速铁路地震信号远程传输中的失真控制。实验结果表明,所提方法丢包率较低,均值约为3%,远程传输时延仅为0.9 s,是一种低误差、高效率的高速铁路地震信号远程传输方法。
        The current long-distance signal transmission method does not realize parallelism between the transmission channel energy and transmission channel signals, which leads to high distortion of long-distance signal transmissions. To improve the long-distance transmission efficiency of seismic signals, in this paper, we propose a new technique for long-distance signal transmission in the seismic monitoring systems of high-speed railways. By adopting a method using parallel seismic signal energies in the signal transmission channel and parallel signal transmission structures in the transmission channel, we realize the bidirectional transmission of signals in the transmission channel. Based on the channel energy transmission structure and the signal transmission process, we made the transmission channel energy and signal parallel, and controlled the distortion of seismic signals in long-distance transmissions of high-speed railways. The experimental results show that the proposed method has a low packet-loss rate of about 3% and a long-distance transmission delay of only 0.9 s. This represents a low-error and high-efficiency long-distance transmission method for seismic signals in high-speed railways.
