摘要
采用AT91RM9200和TMS320F2812高性能处理器芯片,设计了一种基于ARM9和数字信号处理双处理器的馈线远方终端,给出了硬件总体结构,详细介绍了模拟量处理、双口RAM、充电器等关键硬件设计方法,并引入嵌入式操作系统设计主控软件。试验结果表明,终端工作可靠、实时性强,满足配电网自动化系统要求。
A design of feeder terminal unit based on dual MPU with ARM9 and DSP was discussed. It provided total structure of hardware based on chip AT91RM9200 and TMS320F2812. The design method of some key hardware such as analog input processing, dual port RAM and battery charger were also introduced in detail. Embedded real-time operating system was used to design software. Experiment results showed that the feeder terminal unit worked reliably with high real-time performance. It met the requirements of power distribution automation system.
