摘　　要：嵌入式硬件平台的设计以硬件模块化设计和灵活组态技术为基础以减少硬件成本和缩短开周期。提出了一种基于嵌入式技术的可灵活配置的FTU(FeederTerminalUnit)硬件平台设计方案,该平台由数字信号处理器DSP、嵌入式工业芯片组RCM2110、可编程逻辑器件CPLD、双口RAM等硬件组成,不仅在硬件结构上可以重新配置,而且构成其软件系统的监控软件、保护功能、通信模块以及嵌入式操作系统等都可以灵活配置,增强了装置的性能,更好地适应配电复杂多变的需求。The design of embedded hardware platform is based on hardware modularization and flexi-ble configuration technologies,which reduces hardware cost and shortens development period. A re-configurable embedding-technology-based hardware platform design for F T U (Feeder Terminal Unit) is presented,which consists of DSP,RCM2110(Embedded Industrial Module),CPLD,dual-port RAM and others. Both the hardware structure and the software system,including monitoring software,relay functions,communication module and embedded operating system,can be flexibly reconfigured,which enhances the performance of F T U and better meets the demands of the complicated distribution system.
