摘　　要：基于物联网的智慧教室设计方案评价是智慧教室构建可行性研究的重要组成部分。基于物联网的智慧教室设计方案分别从感知层、传输层和应用层三个方向出发,根据教室面积选择不同网络拓扑结构和网关;以网络拓扑结构和网关为主要研究对象,将全寿命周期成本理论应用到基于物联网的智慧教室设计方案评价中,通过对比各方案一次性投入成本、运行成本、维护成本、故障成本和组件废弃成本确定最优设计方案。以某高校基于物联网的智慧教室实际设计工程为对象,得到所研究方法的评价结果,结果显示该方法可有效确定基于物联网的智慧教室最优设计方案,且评价效率和评价精度均优于对比方法。The evaluation of smart classroom design scheme based on Internet of Things is an important part of the feasibility study of smart classroom construction.The smart classroom design scheme based on Internet of Things consists of three layers,named perception layer,transmission layer and application layer.Different network topologies and gateways are selected according to the classroom area.By taking network topology and gateway as the main research objects,the life cycle cost theory is applied to the evaluation of smart classroom design scheme based on Internet of Things,and the optimal design scheme is determined by comparing the one-time input cost,operation cost,maintenance cost,failure cost and component waste cost of each scheme.The evaluation result of the research method is obtained by taking the actual university smart classroom design project based on Internet of things as the object,which shows that this method can effectively determine the optimal smart classroom design scheme based on Internet of things,and the evaluation efficiency and evaluation accuracy are better than the contrastive method.
