摘　　要：介绍了一种嵌入式变电站通信处理软硬件平台。该平台硬件包括主CPU插件和各种功能插件,并由工业以太网、CAN现场总线组成内部通信网络,具有网络化、分布式、模块化、可扩展性和开放性等特点;软件基于嵌入式实时操作系统,采用模块化分层设计思想,设计了通信处理软件平台,实现了数据库管理层、硬件抽象层、通信协议层,层与层之间通过API函数实现松散耦合。在该平台上通过软硬件不同的配置实现了变电站内的远动工作站、保护管理机、嵌入式故障信息子站等通信处理装置,并在各种电压等级的变电站中广泛使用。A HW ＆ SW embedded platform for substation communication processing is introduced. Its HW includes the main CPU and function plug-in units,as well as the internal communication network of industry Ethernet and CAN fieldbus,being networked,distributed,modularized,extensible and open. Its software is based on the embedded RTOS （Real-Time Operation System） and its communication processing software platform is designed with layered and modularized programming. Different layers（the database management, hardware abstraction and communication protocol layers） are loosely coupled by API（Applieation Programming Interface）. The communication processing units with different HW and SW configuration on this platform can be applied to the telecontrol station,the protection management system and the embedded FIS （Fault Information System） of substations at different levels.
