With the rising volume of building in China, the building energy consumption has increased year by year, and it is significant to carry out building energy consumption statistics and energy-saving management.The paper proposed a building energy consumption monitoring system architecture based on the ZigBee wireless sensor networks through the analysis of building energy monitoring system.It investigated network topology control and routing protocols of ZigBee, and also described a process of the system periodic tasks in detail.The experimental results proved that the architecture achieved a high reliability of building energy consumption data collection and wireless transmission.According to statistical analysis of the data on energy consumption, it provides a basis and reference for decision-making to reduce energy consumption and improve energy efficiency in buildings.%随着我国建筑总量不断攀升,建筑能耗也逐年增加,更加有效地实施建筑能耗统计及建筑节能管理具有重要的意义;通过对建筑能耗监测系统的分析,在研究ZigBee技术的基础上,提出了基于ZigBee无线传感器网络的建筑能耗监测系统总体结构,对其网络拓扑控制和路由协议进行了研究,并介绍了系统周期性工作过程;网络测试表明,该系统可靠性好,能够实现建筑能耗数据的采集和无线传输;通过对能耗数据的统计分析,为降低建筑能耗和提高建筑能效,提供了决策依据和参考.
