【摘要】 本文从电能质量在线监测的角度出发,采用基于小波变换和傅立叶变换的电能质量分析方法,设计了以 SANSUNG S3C4480X 为核心的硬件监测系统,并在该硬件系统上移植μC/OS-Ⅱ操作系统内核,在该内核的基础上编写基于小波变换和傅立叶变换的电能质量分析算法应用程序,完成电能质量在线监测任务。更多还原

【Abstract】 Considering on-line monitoring and measurement system of power quality,based on wavelet transform and Fourier transform for power quality analysis,the hardware system is designed base on SANSUNG S3C44BOX.In the paper,on the basis of the special structure of S3C44BOX Microprocessor,through modifying μC/OS-Ⅱ and programming key codes using ARM assemble and C language,the Embedded Real Time Operating System μC/OS-Ⅱ is transplanted to S3C44BOX.Last,according to FFT and Mallat algorithm,the monitor of power quality is controlled on real time.更多还原
