摘　　要：针对已研制的继电保护测试装置对数字化、模块化、小型化、嵌入式人机界面等功能的需求。从硬件结构和软件设计两个方面考虑,该文提出了一种微机继电保护测试装置的监控系统设计方案。整机采用两套DSP+CPLD分别作为信号发生和人机监控模块,其中监控DSP系统赋予了整机人机交互和保护自检功能,系统采用自定义内部通信协议由内部CAN通讯接口传输数据,实现各种继电保护测试功能。文中分析了在监控系统中应用实时操作系统DSP/BIOS的软件结构设计与实现。该系统目前正在一种新型继电保护测试装置中得到应用。In order to satisfy with the needs of digitalize, modular, small and man-machine interface function which applies to the new microcomputer typed relay protection test device and considering the hardware structure and the software, this paper proposes one kind of monitoring system design for new typed relay protection test device system. The machine takes the DSP and CPLD as the signal generation module and the man-machine monitoring system module. The monitoring system module makes this device possess man-machine interface function and protection self-checking function. The system uses the definition of internal communication protocol by the internal CAN interface data communication to achieve a variety of relay testing. The paper analyzes the application of real-time operating system DSP/BIOS software design and implementation of structural in the monitoring system. The system has been currently applied in a new type of relay protection test devices.
