摘要
介绍了一种基于ESPI场强测试设备的数据采集系统的设计与实现,对铁路沿线的GSM-R无线网络的场强数据进行采集、分析.在硬件设备的连接以及触发方面,针对测试要求,采用多种触发和连接方式以适应不同的测试环境;在数据处理方面,采用二分法插入排序,以适应列车在高速行驶过程中采集大量数据及存储的要求;在显示方面,采用在二维坐标系中实时显示数据曲线的方式,使用户能清晰地观察到测试结果,便于进一步的分析.
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.
