基于ARM-DSP的嵌入式配电终端设计

Design of distribution system terminals based on ARM and DSP

采用ARM芯片AT91RM9200和DSP芯片TMS320F2812双组合处理器方案,实现了一种基于嵌入式系统的新型智能化配电终端。该终端解决了传统配电终端体积大、响应速度慢、可靠性不高、功能单一的问题,可以采用高速高精度的数字采样技术对三相电压电流进行监测,完成谐波分析、无功补偿、故障检测等功能,还可以提供友好的人机界面,便于用户进行管理控制。此外,该终端具有丰富的通信接口,可满足电力系统各种复杂的需要。

An intelligent distribution terminal based on the embedded system was proposed. Using ARM chip AT91RM9200 and DSP chip TMS320F2812 as processors, this terminal avoided many problems occurred in traditional distribution terminals such as large volume, low response speed, low reliability and single function. It can accomplish many tasks, including the sampling of analog signals, harmonics elimination, reactive power compensation and fault diagnosis. It can also provide human computer interaction and various kinds of communication interfaces, and thus meet the complicated needs of power system.
