摘要

ZPW-2000A无绝缘轨道电路是我国高速铁路的高端技术成果。本文在ZPW-2000A轨道电路FSK信号解调算法已有研究成果的基础上，设计了基于虚拟仪器的移频信号仿真测试系统。系统以LabVIEW强大的信号处理与数学分析工具给出模拟信号，重点分析测试软件的结构和实现方式，主要包括应用层和人机界面层的设计与实现，并对仿真结果进行分析。%ZPW-2000A non-insolation railway circuit is an advanced achievement of the high speed railway of China. Based on the existing research results of ZPW-2000A track circuit FSK signal demodulation algorithm, a frequency-shift signal simulation test system based on virtual instrument was designed. With LabVIEW powerful signal processing and the mathematical analysis tools the system sent analog signals. This paper mainly analyzed the structure and implementation method of the test software, which included the design and implementation of the application layer and the interface layer. Then, the simulation results were analyzed.
