摘　　要：针对智慧教室整体系统能耗大,节点采集信息传送效率低的问题,提出了基于海计算的智慧教室架构模型,完成了智能节点的设计与实现.通过将物联网的海计算模式融入智慧教室中,并对物联网技术三层模型进行分析与改进,提出了两层结构的智慧教室架构模型;设计了加入MCU的智能节点,并组建了具有自主处理能力的智能节点网络.实验表明,基于海计算模式下的智慧教室可在传感器端实现对教室环境信息的采集、判断和控制;在采集数据准确率相对稳定的情况下,海计算模式下的智慧教室大幅降低了能耗以及信息传送丢包率,具有更好的适用性.In view of the problems such as large energy consumption and low efficiency of node collection and information transmission in smart classrooms,in this paper,we discuss the significance of constructing the smart classroom based on the sea computing in Internet of things,and put forward the model of smart classroom architecture based on sea computing,especially focusing on the design of its intelligent node.By analyzing the computational architecture of the sea computing model and integrated it into the smart classroom to improve the three-layer model of the smart classroom based on the classical Internet of things.Thus,a more concise two-tier model architecture has been presented.And moreover,the intelligent node of MCU is designed,and an intelligent node network with autonomous processing capability is set up.The smart classroom based on sea computing can realize the collection,judgment and control of the classroom environment on the end nodes.The experiments results show that the smart classroom in the sea computing model has significantly reduced energy consumption and information packet loss rate in the case of relatively stable accuracy of the collected data.
