Application of Embedded Technology in Intelligent Electric Meter System

本文介绍了智能电表系统的设计。为了满足智能电网对电表的智能化要求,利用了当前应用非常广泛的嵌入式芯片,确立了该系统的控制核心元件。通过将电网中的强电流电压进行采样,然后将采样信号送到主芯片进行处理,根据所得到的信号,进行电网的监控和报警等功能。主芯片得到处理后的信号,通过RS485通信传输至数据中心的数据库中。系统具有测量精度高、功能多样、系统集成度高和可实时监控等优点。

This paper introduces the design of intelligent electric meter system. In order to meet the needs of the intelligent requirements of the smart grid to Watt-hour meter, the system uses the embedded chip currently widely used to establish the core controlling element of the system. The system samples the strong current and volt-age in the grid, and sends the sampled signal to the main chip to process, and realizes network monitoring and alarm according to the signal obtained. The main chip transmits the signal to the database of the data center through the RS485 communication after obtaining the processed signal. The system has high measurement accuracy, multi-ple functions, high system integration degree and real-time monitoring, etc.
