摘　　要：针对公共建筑能耗日益严重的现状,以及传统能耗监控系统暴露出来的空间约束性强、实时性差、易受环境影响、成本高、移植性差等问题,已很难满足能耗监控系统发展的需求。提出了一种大型公共建筑能耗监控系统的设计方案,该系统包括能耗数据采集节点和能耗监控节点。能耗数据采集节点的主控STM32F407通过RS485模块向智能电表发送命令,获取智能电表的电流、电压、功率等能耗信息,然后通过LoRa无线传输模块将能耗信息发送给能耗监控节点。能耗监控节点采用iTOP-4412核心板且封装了Exynos 4412处理器,通过LoRa无线传输模块接收数据,并实现能耗数据在LCD屏上显示、本地保存、上传服务器。对系统进行测试,结果表明,该系统实现了对能耗信息的采集、发送、接收、显示、保存和上传的功能。It is difficult to meet the development of energy monitoring systems for the current situation of energy consumption in public buildings and the spatial constraints,poor real-time performance,high environmental impact,high cost and poor portabil⁃ity exposed by traditional energy monitoring systems.A design scheme for a large-scale public building energy consumption monitor⁃ing system is proposed,which includes an energy consumption data collection node and an energy consumption monitoring node.The main control STM32F407 of the energy consumption data collection node sends commands to the smart meter through the RS485 module to obtain energy consumption information such as current,voltage and power of the smart meter,and then sends the energy consumption information to the energy consumption monitoring node through the LoRa wireless transmission module.The energy monitoring node adopts the iTOP-4412 core board and encapsulates the Exynos 4412 processor,receives data through the LoRa wireless transmission module,and displays energy consumption data on the LCD screen,locally saves,and uploads the server.The system is tested.The results show that the system realizes the functions of collecting,transmitting,receiving,displaying,saving and uploading energy consumption information.
