摘要
微机保护硬件平台直接决定了微机保护的整体性能,总结了目前广泛采用的四种硬件平台构架模式,分析了多处理器之间的数据交互方式,得出多处理器构架模式具有较好的应用前景这一结论。在此基础上设计了一种通用性好、开放灵活的新型微机保护的硬件平台,采用微控制器(MCU)和数字信号处理器(DSP)协同工作的多处理器构架,实现了对外3路嵌入式以太网通信接口,微处理器之间的数据交互采用DSP的主机接口(HPI)进行,详细介绍了MCU模块、DSP模块、输入输出模块和数据交互模块的功能分配和实现方法。
The performance of microprocessor-based protection is decided directly by its hardware platform.By summing up the four kinds of architecture widely used in digital relays at present and analyzing the form of exchanging data between the microprocessor,this paper draws the conclusion that multi-processor architecture is promising.With the characteristic of opening and universality,a new hardware platform based on MCU DSP architecture is designed.The platform achieves three embedded Ethernet,exchanging data by host-port interface.The function and realization of MCU module,DSP module,input output module and data exchanging module are also introduced.
