Scheme Design of Data Stream Decoding Unit of Transponder Read-write Device
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.
