基于FPGA的便携式应答器检测设备的设计与实现

In the whole railway traffic system, especially in the communication system of high-speed railway system, transponder is the most basic information point. The transponder network constructed by a large number of transponders provides a lot of information for train location and control. The security of the transponder\'s normal work and internal message relates to the safety of the whole railway network, so it is necessary to check the transponder regularly. In this paper, the actual project in the laboratory as the background, the urgency of the equipment requirements and the feasibility of the implementation, the development of a portable transponder detection equipment in order to achieve the corresponding responder detection and information update convenient operation.The equipment has been successfully applied to the maintenance of the transponder.
