Description: DSI-5000 系列微机保护装置是为满足数字化变电站的整体要求而策划设计的，采用通用的软硬件平台。主要介绍了
平台的软硬件特点，比较了采用单 CPU 和多 CPU 方案实现 IEC61850 通讯协议的优缺点，给出了可编程模块的建模实例和实
现方法。阐述了在VxWorks操作系统下任务优先级、中断优先级的分配方法以及任务调度机制。介绍了IEC61850 通讯规约
的实现过程。 - DSI-5000 serial relays are designed for the need of digital substation, using general hardware and software platform.
This paper mainly introduces the advantage of the general hardware and software platform, also compares the advantage and
disadvantage of the method realizing IEC61850 standard with single-CPU and with multi-CPU. The paper presents the modeling and
realization of programmable relay. The paper also introduces how to assign the priority of task and interrupt, and how to dispatch the
task, also introduces the process of realizing IEC61850 standard.
