摘　　要：针对铁路线路复杂和恶劣的测试环境,设计了轨边数据采集系统,本系统利用无线传输模块进行传输,使远程数据采集、分析和处理成为现实,更少地受到自然条件的制约。本设计采用一种以Altera FPGA为核心控制器,通过对模拟开关ADG408、模数转换器AD976控制,实现了8路模拟信号的采集;同时利用单片机C8051F020对GPRS网络模块MC37I控制,实现无线数据控制和传输。Aiming to the complexity of the railway line and the harsh test environment, the Railway Track Edge Data Acquisition System was designed. The System was used wireless transmission module to make transmission, the remote data acquisition of analysis and processing become true, and be less restricted by natural conditions. In this design, the Altera FPGA was used as the core controller. Through controlling the analog switch ADG408 and analog to digital converter AD976, the eight analog signals acquisition was implemented. At the same time, the wireless data control and transmission were implemented by using C8051F020 MCU to control MC37 I module of GPRS network.
