摘　　要：论文设计并实现的智能用电管理系统由3部分组成:智能电子电能表(iEPM)、智能用电管理集中器(iEMC)以及智能集中式数据库服务器(iCDS)。iEPM安装于建筑物的每一个房间内,由于其基于阻抗鉴别技术,所以可以自动识别房间内所连接的电器设备;iEPM同时也是一种高精度的电子电能表,可以直接替代目前广泛使用的电能表,而无需重新布线。iEMC采用基于WiFi技术的无线传感器网络,将一定数量的iEPM的通讯数据经处理和汇总后传递给iCDS。iCDS采用多层体系架构,易于功能程序的扩展,其可自动向iEPM发送数据或更新iEPM程序。论文设计的智能用电管理系统大幅度的提升了建筑物内的用电效率和用电安全,特别适合在高等院校、智能楼宇以及企事业机关等场所进行广泛应用。This paper presents the design and implementation of the intelligent power management system, which consists of three part: the intelligent Electronic Power Meter(iEPM), the intelligent Electronic Management Concentrator(iEMC), and the intelligent Centralized Database Server(iCDS). The iEPM will be installed in every home of building;because it is based on the technology of impendence identification, iEPM can automatically distinguish which electronic appliance is connected in home. The iEPM is a high precision electronic power meter, so it can replace Electricity Meter currently and require no extra indoor wires. A certain amount of iEPM can be added to a group controlled by an iEMC which adopts the technology of WiFi-based WSN so that it can exchange the message with iCDS. The iCDS solves the key problem of system extension by using the multi-layered architecture;it can automatically send data to the iEPM or update the program of the iEPM. The intelligent power management system can make people use power with safety and efficiency. Using this system, the users or managers of the building can decide which electronic appliance can be used in which time up to their requirement.
