摘　　要：介绍了使用NI设备对车地通信系统中FSK(频移键控)信号进行数据采集的方法,以及基于LabVIEW的FSK信号调制解调的方法。车地通信检测装置的研发,解决了车地通信轨旁检测无专用设备的难题,并能够实现检测结果的直观性及技术指标的定量分析。该装置的应用为上海轨道交通2号线的车地通信信号维护提供了有效手段,节约了维护成本,为后续的信号检测及轨道电路信号检测奠定了基础。The use of NI equipment in the system of TWC FSK is introduced, which collects the signal data based on LabVIEW of FSK signal modulation demodulation method. The train- to - wayside communication detection device for Shanghai metro Line 2 in TWC signal maintenance pro-vides an effective means, it saves maintenance cost, creates considerable economic benefit, and lays the foundation for subsequent signal detection and track circuit signal detec-tion. The development of this device could solve problem like the TWC wayside detection without special equipment, and realize the intuitive detection and technical index of the quantitative analysis.
