设计实现的智能家居电能监控系统由电能监控从站和电能监控主站组成，电能监控从站采用 EM773作为主控芯片实现电能的计量、数据的存储管理以及液晶实时显示当前电能信息。电能监控主站主要实现上位机和电能监控从站之间的指令、数据转发功能。多个电能监控主站之间通过 CAN 总线连接组成局域网，通过 nRF24L01芯片进行电能监控从站组网和电能从站连接。由上位机、电能监控主站和电能监控从站组成监控网络，便于今后智能化电能信息管理。%The slave and master stations of energy monitoring and controling make up the monitoring system. With EM773 as the master chip of slave stations,energy measurement,data storage and management,and the LCD displaying the current energy information in real time can be realized. The master station of energy monitoring is used for transferring control commands and data between the host computer and the slave stations. The master stations interconnect by CAN bus,connect the slave stations by the chip nRF24L01,and form the LAN. A host computer,slave stations and master stations form a strong network of intelligent energy information management for the future. The whole system is beautifully structured with easy operation and maintenance,wide monitoring and low power consumption.
