摘　　要：针对传统电力机车的改造项目,设计了一种基于ARM9处理器S3C2440、Windows CE嵌入式操作系统和机车故障诊断显示技术的全新机车智能显示终端(IDT)。该显示终端具有机车当前运行状态和实时故障数据的采集、显示、存储和发送等功能。设计了显示终端的硬件结构,进行了操作系统的定制、SPI流接口驱动程序的编写和应用程序以及嵌入式数据库的设计。该系统已成功应用于SS3电力机车,且系统扩展性能良好,稍加改善便可应用于汽车客货运输等其他领域。具有广阔的应用前景。A new locomotive intelligent display terminal（IDT） is designed,which is based on ARM processer S3C2440,Windows CE embedded operation system and technology of locomotive fault detection display.This IDT can realize collection,display,storage,transmission of fault data and real-time running information.Hardware structure,OS customization,SPI driver programming,application programming and embedded data base are designed and developed.With the strong scalability,the design can be used in other areas by modifying a little,so it has great application prospect.
