电气化铁路轨道电路干扰信号检测新方法

A new method for measuring disturbance signal of track circuit in the electric railways

提出了一种基于耦合绝缘子的新型检测方法。为了提高测量精度,采用参数估计的算法用来校准新型测量装置的传输函数;并通过对信号处理单元的校准来补偿相位差。实验表明:该测量方法可以精确地测量高频率干扰信号。

A new method based on capacitive insulator is proposed in this paper. For improving the measurement accuracy, we not only adopt the parameter estimation algorithm to calibrate the transfer ratio of the new measurement system, but also calibrate the signal processing unit to compensate the phase separation. The laboratory tests prove that this method could be utilized to measure interference signals with higher frequencies.
