摘要
随着生活水平的提高,居民用电量快速增加,对电网的稳定运行造成不利影响。智能电表的应用有助于平衡电力峰谷负荷。本文介绍了一种单相智能电表设计方案。系统采用模块化结构,包括电量采集、数据存储与显示和远程通信三部分。电量采集模块对配电线路的电压、电流进行采样,经由CS5460A电能计量芯片得出电能信息;按键电路、数码管与存储单元用于电能数据的查询、显示及存储。智能电表采用Modbus RTU通信协议实现与上位机的远程通信。该设计方案对提高电能表的智能化程度有一定的实用价值。
With the improvement of living standard,electricity consumption of residents increases rapidly,which adversely affects the stability of power grid.Smart meter is conducive to counterweigh the peak and valley power loads.This paper presents a design scheme of single-phase smart meter.The system adopts modular structure,including power acquisition,data storage and display and remote communication.Power acquisition module takes sample of the distribution line voltage and current,while CS5460 Acomputes electric energy information;the key circuit,LED and storage unit are used for query,display and storage of electric energy information.The remote communication of smart meter and upper PC is based on Modbus RTU communication protocol.This design has certain practical value for the intelligence of electric energy meter.
