摘　　要：本文给出了一套基于FPGA的应答器读写装置数据流解码单元的方案设计,该解码单元可以对列控中心(TCC)与地面电子单元(LEU)之间的串口通信数据进行数据流解码,通过解码出的数据与应答器读写装置读出的有源应答器数据进行数据比对可以判断出LEU设备是否工作正常,弥补了目前应答器读写装置无法判定LEU工况的功能缺失,本文同时给出了解码单元的硬件设计架构、工作流程以及部分FPGA的代码。现场试验中解码单元分别在多个铁路线路及地铁线路进行功能测试,其性能稳定可靠,并准备进一步的测试和推广运用。The essay gives out a project design which is based on FPGA transponder reader data stream decoding.And the decoding unit can decode the data stream to the serial communication data which is between TCC and LEU.Comparing the decoded data with the activate transponder data read out by the transponder read-write device,we can judge that whether the device is running well,which make amends for the function loss that the transponder read device cannot determine the LEU condition.At the same time,this text renders the hardware design framework of decode unit,workflow as well as some FPGA codes.In field test,decode unit will conduct the function test in several railway routines and subway routines respectively,and for its steady and reliable performance,it will be further tested,promoted and used.
