【摘要】：建设坚强智能电网,是当前中国电网的发展目标,并已经进入大规模实施阶段。作为坚强智能电网重要组成部分的电能信息采集系统,是电网智能化的“最后一公里”,该系统主要由集中器、采集器、智能电表等组成,相对采集器和智能电表,系统要求集中器的功能强大,可靠性更高,稳定性更好。本文根据国家电网公司对集中器最新的相关技术规范要求,围绕如何实现集中器功能,提高设备可靠性和稳定性,结合最新的嵌入式应用技术,最后选用ATMEL公司的ARM9核芯片AT91SAM9260作为核心处理器构建整个系统,设计出了基于ARM9核的远程抄表集中器。在集中器设计阶段,详细分析需求,紧紧围绕功能,采用模块化的设计思想进行软硬件设计,各部分功能相对独立,从根本上保证了可靠性,同时提高了开发的效率。根据硬件原理图设计出了印制电路板,根据软件流程图编写代码,并进行了调试和验证,最后完成了软硬件联合调试,制作出了样机。结果证明,设计达到了预期目标,实现了良好的经济效益和社会效益。
[Abstract]:Building a strong smart grid is the current development goal of China's power grid, and has entered a large-scale implementation phase. The electric energy information collection system, which is an important part of the strong smart grid, is the "last kilometer" of the intelligent power grid. The system is mainly composed of concentrator, collector, intelligent meter, relative collector and intelligent meter. The system requires the concentrator to be powerful, reliable and stable. In this paper, according to the latest relevant technical specifications of the concentrator of State Grid Company, we focus on how to realize the function of concentrator, improve the reliability and stability of equipment, and combine with the latest embedded application technology. Finally, a remote meter reading concentrator based on ARM9 core is designed by using ARM9 core chip AT91SAM9260 of ATMEL company as the core processor to construct the whole system. In the stage of concentrator design, the requirement is analyzed in detail, and the software and hardware are designed closely around function. The function of each part is relatively independent, which guarantees the reliability and improves the efficiency of development. The printed circuit board is designed according to the hardware schematic diagram, the code is written according to the software flow chart, and the debugging and verification are carried out. Finally, the joint debugging of the hardware and software is completed, and the prototype is made. The results show that the design achieves the expected goal and achieves good economic and social benefits.
