摘要
针对现有金属氧化物避雷器在线监测系统抗干扰能力差,数据处理不准确,工作不稳定等诸多问题,设计了基于ARM控制芯片和ZigBee技术的MOA在线监测系统,给出了系统的整体设计方案,完成了信号采样、调理单元和ARM终端的设计.采用有线和无线通讯相结合的方式进行通讯,采取屏蔽、接地和隔离等措施进行抗干扰处理.进行了系统主程序、工况辨识子程序、信号采集与分析子程序和通讯子程序等软件设计,采用组态软件技术设计了系统的上位机软件.对数字滤波、FFT变换和基波电流峰值的提取等进行了仿真分析,仿真结果验证了系统的可行性和有效性.
Metal Oxide Arrester（MOA）on-line monitoring system based on ARM chip and ZigBee technology has been designed in this paper to overcome the problems of existing MOA such as poor anti-interference ability,inaccurate data processing and instability.Under the overall design of the system,signal sampling unit,signal conditioning unit and ARM terminals have been completed.Wired and wireless communication,shielding,grounding and isolation,etc.anti-interference measures have been used in the system.Software design consists of main program design,state identification subroutine design,signal acquisition and analysis subroutine design and communication subroutine design and so on.The upper computer software system adopts configuration software technology.A simulation analysis of the digital filter,FFT transformation and fundamental current peak extraction is obtained.The simulation results verify the feasibility and effectiveness of the system.
