摘　　要： 根据配电网数字式综合电流保护 ( DCPR)的功能要求和结构特点 ,对嵌入式实时操作系统μC/OS- 加以改进。改进后的 μC/OS- 只占用不到 3k B的程序空间 ,运行时 CPU资源占用减少了 30 %,具有优先级继承功能 ,更加适合在电力监控领域的应用。基于 μC/OS- 设计的 DCPR系统运行流畅 ,实时性好 ,软件代码的可移植性、可扩展性和可维护性强 ,大大缩短了整个系统的开发周期 。 Owing to the requirement of digital current protection relay (DCPR), some methods for improving performance of μC/OS Ⅱ and reducing the size of its code are presented and described. The code size of improved μC/OS Ⅱ is less than 3 kB and the CPU resource occupation reduces by 30% than before. Moreover, improved μC/OS Ⅱ has priority inheritance, which makes it very suitable for the application in industrial control field. The improved μC/OS Ⅱ based DCPR system not only has good real time performance, but has approved portability, extensibility and maintainability in software code. All these make the development cycle and cost reduce greatly. This project is supported by Research Fund for the Doctoral Program of Higher Education (No.2000069808).[KH2D]
