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 MC37I module of GPRS network.
