摘要
集中器是整个抄表系统的重要组成部分,其工作情况决定了抄表系统的稳定性,本文分析了集中器的功能,详细介绍了集中器的设计过程,包括集中器总体设计、集中器硬件设计和集中器软件设计等.通过引入嵌入式处理器芯片S3C2410,嵌入式LINUX操作系统和载波芯片MI200,使集中器成为具有多线程工作,多频点传输,多种方案互补的稳定的抄表系统核心.通过小范围测试,数据在单相电力线上的发送接收效果良好.
The concentrator is an important part of the automatic meter reading system,its work decides the steady of a system are analyzed. system. The functions of The designs including concentrators are introduced. Through the use of Linux embedded operation system and power-line the concentrator in the automatic meter the structure, hardware and software reading of the the 32-bit structure microprocessor S3C2410,the loaded wave chip Mi200,the concentrator becomes a stable core of the automatic meter reading system with multi-threading work,several selectable carrier frequency transmitting and multi-proposal inter-supplementing. The system has been tested in a small scope and the sending and receiving data are fine in the single-phase power lines.
