This paper introduces the signal data acquisition method of the FSK signal using NI equipment in the track circuit system, and the FSK signal modulation demodulation based on LabVIEW . The track circuit communication detection device for Shanghai metro line 2 provided effective means, saved maintenance costs, created the economic benefit and laid the foundation for subsequent signal detection. solved the problem that without special equipment detection in wayside, it can also realize the results of detection intuitively and the quantitative analysis of technical index
