This paper introduces the design and realization of a kind of data collecting system based on ESPI(field-strength test equipment) which collect and analyzes the field intensity of GSM-R(global system for mobile communications-railway) along the line of the railway.With respect to the mode of hardware connection and trigger,we use various methods in order to adapt to different test environment;to the data processing,adopt Dichotomy-Sort in order to adapt to the high-speed data acquisition and storage;to the data displaying,render the real-time data curve in the two-dimensional coordinate,by which users can clearly observe and analyze the test result.This system has obtained good results in practical application.
