基于DSP和ARM9的电能质量在线监测仪的设计

Design of Power Quality Online Monitoring Equipment Based on DSP and ARM9

介绍了一种基于DSP和ARM9的电能质量监测仪的设计方案。DSP负责电网参数采集和数据计算,ARM9负责网络通信和数据管理。通过移植成熟的嵌入式实时操作系统Linux为设备提供软件平台,利用嵌入式Web服务器和CGI技术实现电能质量数据和Internet相连,达到远程监控的目的,采用图形界面开发工具QT进行人机界面开发。实际测试证明系统运行稳定、高效,满足了电能监测的要求。

This paper introduced a solution for power quality online monitoring equipment based on DSP and ARM9 core processor.The equipment used DSP for power parameters acquisition and data calculation and used ARM9 network communication and data management.Mature embedded real-time operating system Linux was transplanted for the device as software platform.Embedded Web server and CGI technology was used for connecting power quality data to Internet,in order to achieve remote monitoring purposes.Moreover,QT graphical interface development tools were used for human-machine interface development.By actual test,the results prove that the system is stable,efficient and can meet the power monitoring requirements.
