摘　　要：设计并实现了一种基于双核平台的分布式电能质量监测仪,将数据分析处理与外围控制完全独立,利用CPLD产生外围器件的控制时序,充分利用DSP资源,以满足电能质量监测精度及实时性的要求。介绍了监测仪的信息采样电路、通信模块电路、存储模块电路和软件流程,并对各模块的功能、特点及具体设计作了阐述。An electrical energy quality online monitoring device based on two CPUs was designed and implemented. The data analysis was separated from the peripheral control completely. CPLD （complex programmable logic device ） was used to generate control timing of peripheral devices. Full use of the DSP was made, so as to meet the requirements： monitoring precision and real time. The paper introduced the monitor＇s sampling circuit, communication module circuit, storage module circuit and the flowchart of software. Then, the functions, features and designations of each module were described.
