Worldwide buildings are responsible for about 40% of the overall consumption and contribute to an average of 30% percent of the global carbon emissions. Nevertheless, most current buildings lack efficient energy management systems because such solutions are very expensive, especially when necessary instrumentation needs to be installed after the building’s construction. As an alternative, we purpose the use of IoT sensor networks to retrofit existing medium and large-sized buildings to provide energy management capabilities in a cost-effective way. An IoT network auto-configuration platform for building energy management was developed. In order to efficiently manage metadata related to location and devices, a database using dynamic QR codes was created. Furthermore, we discuss the potential and shortcomings of different sensor-gateway pairing strategies that are applicable to an auto-configuring system. Lastly, we share our implementation of these concepts and demonstrate their use in a medium-sized building case study. The results show a trade-off between optimal configuration and total configuration time with a focus on the quality of the communication signal strength. The proposal provided the necessary automation for a cost-effective energy management system that can be deployed in both new constructions and existing buildings.

基于二维码的建筑物联网传感器网络自动配置框架

全球建筑约占总消耗的 40%，平均占全球碳排放量的 30%。然而，大多数当前的建筑物都缺乏高效的能源管理系统，因为此类解决方案非常昂贵，尤其是在建筑物建成后需要安装必要的仪器时。作为替代方案，我们旨在使用物联网传感器网络改造现有的大中型建筑，以经济高效的方式提供能源管理功能。开发了楼宇能源管理物联网网络自动配置平台。为了有效地管理与位置和设备相关的元数据，创建了一个使用动态二维码的数据库。此外，我们讨论了适用于自动配置系统的不同传感器-网关配对策略的潜力和缺点。最后，我们分享我们对这些概念的实施，并展示了它们在中型建筑案例研究中的使用。结果显示了最佳配置和总配置时间之间的权衡，重点是通信信号强度的质量。该提案为经济高效的能源管理系统提供了必要的自动化，该系统可以部署在新建筑和现有建筑中。结果显示了最佳配置和总配置时间之间的权衡，重点是通信信号强度的质量。该提案为经济高效的能源管理系统提供了必要的自动化，该系统可以部署在新建筑和现有建筑中。结果显示了最佳配置和总配置时间之间的权衡，重点是通信信号强度的质量。该提案为经济高效的能源管理系统提供了必要的自动化，该系统可以部署在新建筑和现有建筑中。
