基于Android系统的电力谐波检测仪
Detection device for power harmonic based on Android system
摘要
Abstract
According to the current situation of power quality in power system, a portable detection device for power harmonic based on Android is designed.This paper introduces the hardware implementation scheme and software design methods of detector.The circuit of data acquisition module based on the 16 bits, 6 channels simultaneous sampling chip of AD7606.Cortex-A9 platform which has equipped with Android operating system can complete configuration management and achieves data processing, data storage, human-computer interaction.The add window FFT algorithm is chosen to achieve data processing which can reduce the detection error caused by fence effect and spectral leakage problems.Test results show that this detector can extract the harmonic information and meet the testing requirements.关键词
