面向智能家居的实时电能信息采集系统设计

Real time data acquisition system for electric power consumption of the smart home

通过对智能家居内部的用电负荷进行实时监测、并对不同负荷的运行实施优化安排,能够有效实现节能降耗的目标。为此,设计了以STM32嵌入式系统为核心的电能信息实时采集系统。该系统包括电能信息采集、无线通信、显示、存储和故障报警等模块,能够实现用电信息的实时采集、显示,历史数据查询和故障报警功能。实验结果表明,本系统有助于实现负荷运行的精细化管理,满足智能家居的需要。

Real time monitoring of the power consumption and optimized operation of the electric loads in the smart home enables the goal of energy conservation to be achieved. Then the ARM STM32 embedded system based real time data acquisition system is design in this paper. The presented system consists of the modules of power consumption data acquisition, wireless communication, LCD display, data storage, and fault alarm, which provides the functions of real time data acquisition on power consumption, display and query of historical data, as well as fault alarm. Experimental results show that the presented system facilitates elaborated managements of electric load operation, meeting the requirements of the smart home.
