摘　　要：研制了一种由数字信号处理(DSP)和嵌入式微处理器(ARM)双系统构成的电能质量监测系统,详细阐述了系统的软硬件设计.该系统利用DSP控制信号的同步实时采集和分析计算,采用嵌有Linux系统的ARM通过SPI实现与DSP的通信,获取电能质量的分析数据与原始数据并传输系统指令,采用大容量存储设备实现数据的本地存储,提供智能友好的交互界面和无线通信功能.实验测试结果表明,该系统实时性好、精度高、可扩展性强,满足各项指标要求.A monitoring system composed of the DSP and ARM dual system is developed, and the design of hardware and software is elaborated. This system uses the DSP to control the synchro- nous and real-time collection and analysis and calculation of signals, ARM embedded Linux system communicates with the DSP via SPI, to obtain the original data of power quality and transmit the instruction of system, and use the large-capacity storage device to store the local data, and provide the intelligent and friendly interface display and wireless communication capabilities. The test re- sults show that the system has good real-time, high precision, strong expandability, and meet the re- quirements of indicators.
