摘　　要：Zoom-FFT技术在最近几年在社会各个行业得到了广泛应用,尤其是在铁路信号的检测和处理上,更是取得了较好的效果,能够精准测量轨道移频信号的特征参数值,帮助列车实现数据信息的稳定传输。因此,本文重点对基于Zoom-FFT的铁路信号异常检测系统进行设计。设计A/D转换电路,在电路中进行信号检测传感单元,完成系统的硬件设计;设计Zoom-FFT下异常信号检测逻辑指令,依据指令完成Zoom-FFT模态移频铁路信号异常检测结构的创建,完成软件设计。最终的系统测试结果表明:相比于传统的读取检测组,本设计铁路信号异常检测系统得出的检测误差率相对较低,说明检测效果相对更好,具有实际的应用意义。Zoom-FFT technology has been widely used in various industries in the society in recent years, especially in the detection and processing of railway signals. It has achieved better results. It accurately measures the characteristic parameter values of track frequency shift signals and helps trains. Realize the stable transmission of data information. Therefore, a railway signal anomaly detection system based on Zoom-FFT is designed. Design the AD conversion circuit, carry out the signal detection sensor unit in the circuit, and complete the hardware design of the system;design the abnormal signal detection logic command under Zoom-FFT, and complete the creation of the Zoom-FFT modal frequency shift railway signal abnormal detection structure according to the command. Complete the software design. The final system test results show that: Compared with the traditional reading detection group, the detection error rate of the railway signal anomaly detection system designed in this paper is relatively low, indicating that the detection effect is relatively better and has practical application significance.
