摘　　要：针对KZ4A型机车用传动控制单元故障存储方式升级需求,提出了一种机车故障数据存储解决方案。通过利用高性能浮点DSP对高速AD采集的故障数据进行计算、储能延时和大容量存储技术,实现了机车故障时机车相关数据的有效记录,给出了装置的完整设计框图并阐述了故障记录判断的软件流程。所设计的故障存储装置弥补了老一代TEC_DU2103A型DCU故障存储的短板,缩短了现场故障实时分析时间。A solution of locomotive＇s failure data storage was given for the updating desire of KZ4A locomotive＇s DCU. Using high performance DSP to calculate the failure data collected by high-speed AD convertor, and using the technology of power storage and mass storage, 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.
