摘要
提出并设计了一种基于ARM的嵌入式电力负荷管理终端。该终端以高性能的32位ARM处理器和嵌入式实时操作系统μC/OS-Ⅱ为核心,采用专用的电能计量芯片采集和处理现场电网数据,实现数据存储与传输、异常事件监测和远程负荷控制等功能。终端通过GPRS方式与主站进行通讯,主动上传各种数据或响应主站的各种命令。同时,通过本地人机交互接口也可方便地对终端进行操作。该终端具有可靠性高、实时性好、运行费用低等特点。文章论述了终端软、硬件的结构及其设计思路。
An embedded power load management terminal based on ARM is presented and designed in the paper. The terminal is designed with high performance 32-bit ARM microprocessor and embedded real-time operating system μC/OS- Ⅱ, accompanying with energy measurement IC to acquire and process the data of power grid, implementing data storage and transmission, exceptional event monitoring and remote load control. The terminal communicates with master station by GPRS, uploads data initiatively or responds to master station. In the meantime, the terminal can be operated through human-machine interface conveniently. The design improves the reliability, real-time performance of the terminal and reduces the cost of operation. In addition, the paper discusses the structure of hardware and software as well as the thought of design.
