A solution of locomotive’s failure data storage was given for the updating desire of KZ4A locomotive’s DCU. Using highperformance DSP to calculate the failure data collected by high-speed AD convertor, and using the technology of power storage and massstorage, a locomotive’s failure data storage device was designed. The hardware structure and software block diagram had been introduced.The device enhances the function of old DCUs as TEC_DU2103A, and shortens the analysis time of the field failure.
