摘要
介绍了基于变电站的远程抄表系统,给出了系统的结构框图和按照3层体系结构进行设计的设计方案,以及基于ARM的设计平台、采用LPC2214微处理器的硬件电路设计。对系统的通信方案进行了详细的阐述。介绍了通信方式的选择及通信模块的软件设计。采用嵌入μC/OS-Ⅱ操作系统的ARM平台具有可靠性高、实时性强、传输速度快等特点。该系统实现了电力系统多功能电表的数据与远距离主站间通过以太网的透明传输。
A substation meter reading system based on ARM is introduced,and its structure and three-layer design scheme are presented,as well as the hardware circuit with microprocessor LPC 2214 based on ARM platform. The communication scheme is described in detail. The selection of communication mode and the software design of communication module are introduced. The ARM with embedded real-time operation system μC/OS-Ⅱ has high reliability, strong real-time performance and high transmission speed. The system realizes the transparent data transmission between muhifunctional ammeter and remote master station via Ethernet.
