摘　　要：针对目前公用变压器数量众多、分散,并且缺乏自动化监测手段的特点,设计一种公变在线监测终端,通过GPRS无线模块实现公用变压器运行参数的远程传输,达到实时监控的目的。通过充分挖掘LPC2132的数字信号处理能力,用汇编语言设计高效的FFT算法,以满足谐波分析的实时性要求。本文主要介绍终端的硬件构成、软件设计思想以及电能质量分析算法。In allusion to the phenomenon that the large number of common transformer lacking the ability of automatic monitoring,this thesis designs a type of on-line monitoring for common transformer to meet the demand of real-time harmonic analysis.It makes full use of the ability of digital signal processing with LPC2132 and designs a high-efficiency Radix-4FFT algorithm with assembly code.This thesis introduces the terminal＇s hardware design,software design and power quality analysis algorithm.
