摘要
探讨了基于ARM核微处理器的数字继电器设计思想,提出了采用S3C44B0X芯片作为数字继电器硬件核心及在硬件系统中嵌入多任务实时操作系统μCLinux的方案,并就系统组成与功能实现做了简要介绍。该设计方案充分利用了基于ARM内核的微处理器件的系统性能,发挥了嵌入式操作系统在网络通信方面的软件编程优势,使得产品性能价格比与其它同类产品相比有较大提高。实验表明,该数字继电器性能良好,在电力系统自动化过程中有着广泛的应用前景。
The design thought of digital relay based on micro-processor with ARM core is discussed in the paper, and in the project S3C44BOX chip is chosen to be the core of hardware of digital relay and the multi-task and real-time operation system μCLinux is embedded into the hardware system. Furthermore, the composition and functions of the relay system are also introduced. The design project fully utilizes the performances of ARM core and the programming advantage of embedded system in network communication so that, the performance price ratio of the relay has been improved highly compared with alike products. The experimental results show that the digital relay has good performances which will be applied widely into automatic processes in electric power systems.
