Internet of things intelligent building environment monitoring method based on NB-IoT and ZigBee

现阶段,物联网技术已经广泛应用到智能建筑行业中,但在环境监控方面依然较为薄弱,智能建筑安全水平仍然不高,提出基于窄带物联网(NB-IoT)和ZigBee的物联网智能建筑环境监控方法。融合NB-IoT和ZigBee无线通信技术生成无线组网,将智能传感器作为数据采集节点,获取智能建筑环境监控数据,并对获取到的数据进行预处理。搭建多层簇网络结构,动态化选取簇头,融合全部环境监控数据并构建智能建筑风险矩阵。通过计算智能建筑风险数值评估建筑风险,从而实现智能建筑环境监控。实验结果表明,应用该方法后环境监控网络能耗更低,环境监控数据融合时间更短,智能建筑风险评估结果更加接近实际评估结果,充分证实了该方法具有较好的智能建筑环境监控效果。

At this stage, the Internet of Things technology has been widely used in the intelligent building industry,but it is still weak in environmental monitoring, and the security level of intelligent buildings is still not high.Therefore, the Internet of Things intelligent building environmental monitoring method based on Narrow Band Internet of Things(NB-IoT) and ZigBee is proposed. Integrate NB-IoT and ZigBee wireless communication technologies to generate a wireless network, use intelligent sensors as data acquisition nodes to obtain environmental monitoring data of intelligent buildings, and preprocess the acquired data. Build a multi-layer cluster network structure, dynamically select cluster heads, integrate all environmental monitoring data and build an intelligent building risk matrix. The intelligent building environment monitoring is realized by calculating the intelligent building risk numerical value to evaluate the building risk. The experimental results show that the energy consumption of environmental monitoring network is lower, the time of environmental monitoring data fusion is shorter, and the risk assessment results of intelligent building are closer to the actual assessment results, which fully confirms that the method has better environmental monitoring effect of intelligent building.
