摘要
介绍了基于ARM7和μC/OS-II的嵌入式系统在直流系统接地故障检测中的应用。针对复值小波变换的检测方法进行硬件和软件设计,构建一套检测系统,并对其可行性进行了验证。将ARM嵌入式系统引入直流系统接地故障检测领域,弥补了以往基于单片机设计的检测系统无法实现先进算法的缺陷。
In this paper, the application of embedded system based on ARM7 and μC/OS-Ⅱ in DC system grounding fault detection is introduced. A detecting system is constructed by hardware and software designing to implement the detecting method based on complex wavelet transform. This system is proved to be feasible by simulations and experiments. This paper introduces ARM embedded system into the field of DC system grounding fault detection, which makes it improved that SCM cant implement advanced algorithm in grounding fault detecting system.
