摘要
介绍一种以 STR912Fw44为核心的基于以太网的多功能电量监控系统。采用 RTL8019AS以太网控制器芯片制作以太网网关。采用高精度的互感器和改进的软件同步交流采样方法进行电力参数的采集。另外,利用判断功率因数 cosφ值,实现了判断恶性负载的要求。本课题最终实现将嵌入式电量监控装置接入以太网,实现电量监控、管理的网络化。
Multifunctional electric energy supervisory control system with STR912FW44 acted as core based on Ethernet is introduced. The RTLS019AS is chosen as Ethernet controller and made of Ethernet gateway. Using the high precision transformer and improved software synchronization alternating current sampling method to acquire the electric power parameters. Moreover malignant loads can be judged by judging from power factor COSφ. That embedded supervisory equipment of the electric quantity connect with Ethernet is realized, realizing the electrical energy metering supervisor and managing networking.
