基于ARM和DSP的嵌入式电能质量监测仪的设计

摘要

We design a type of power quality monitor based on dual-core CPU, DSP and ARM combined with the hardware of high-speed simultaneous-sampling A/D converter, dual-port RAM and other hardware components. The hardware and software design and principle of the main functional model were expounded. Through the embedded Windows CE operating system in the ARM chip, we can operate and control the data acquisition module, as well as display, manage and network upload the monitoring data. The practicality and the accuracy of the instrument were proved in the standard signal source experiment.%设计实现了一种以DSP和ARM双CPU为核心,结合高速同步A/D转换器、双口RAM等硬件组成的监测系统.阐述了主要模块的软硬件设计和原理,并通过ARM芯片的嵌入式Windows CE操作系统,实现对数据采集模块的操作控制,以及监测数据的显示、管理、网络上传等功能.标准信号源实验验证了本仪器测量的可行性和准确性.
