摘要
提出了一种B/S模式下电力系统远程监控的新的实现方案。通过采用同步交流采样技术进行电网运行参数的数据采集并采用快速傅立叶变换对数据进行计算处理,同时在嵌入式实时操作系统C/OS上移植了TCP/IP协议栈LWIP(基于ARM7微处理器)并开发了嵌入式文件系统(EFS),在此基础上裁剪并实现了HTTP协议,从而构建了一个瘦Web服务器,实现了基于Web的远程实时监控。实验结果表明,系统功能强大,具有稳定性高、实时性强的特点。
Based on B/S mode, a new design method of remote monitor for the power system is presented. In the system, the operation parameter data of the electrical network is collected by applying synchronous A. C sampling, in addition, the data is calculated by applying fast Fourier transform. At the same time, a TCP/IP protocol stack LWlP is ported on the embedded RTOS μC/OS and a embedded file system is developed, on the basis of which the HTTP protocol is clipped and implemented, thus, a thin web server is developed and the web-based real-time remote monitor is realized. The experimental result shows that the system is powerful and has the characteristics of high stability and real time performance.
