The current teaching mode mostly uses multimedia for teaching, but in the process of teaching, we have encountered some problems about information preservation and data query. Nowadays, the development of education is becoming more and more rapid, which means that traditional education methods can no longer adapt to the new development situation. For this reason, we analyzed the preparation and teaching methods of several higher teachers, and summarized them. Developed a practical and real-time online learning system that interacts with preparations and lectures. This paper summarizes the research status of wireless sensor network energy consumption at home and abroad. In addition, this paper analyzes the hardware structure and design of sensor nodes and the main algorithms and protocols required at each level on the premise of studying the sensor network architecture. In this article, we analyzed the hardware and protocol stack, and found the main reason for the energy consumption of sensor nodes, and also constructed the mathematical model required for wireless transmission energy consumption. Starting from the original compressed sensing method, this paper mainly studies the data collection method and data reconstruction method in wireless sensor networks. Finally, with the support of compressed sensing technology, we use receivers, transponders, etc. as part of the hardware structure, and at the same time, through the design of interactive teaching software, namely compressed sensing gateways, data access services, etc., we have established an interactive classroom teaching The framework of the system, through the design of the teaching system framework, teachers can answer questions, attendance, evaluation and other activities during online teaching, which greatly improves the development of classroom interactive teaching.

目前的教学模式多采用多媒体进行教学，但在教学过程中，我们遇到了一些信息保存和数据查询的问题。如今，教育的发展越来越快，这意味着传统的教育方式已经不能适应新的发展形势。为此，我们分析了几位高级教师的准备和教学方法，并对其进行了总结。开发了一个实用的、实时的在线学习系统，与准备和讲座互动。本文总结了国内外无线传感器网络能耗的研究现状。此外，本文在研究传感器网络架构的前提下，分析了传感器节点的硬件结构和设计以及各层级所需的主要算法和协议。在本文中，我们分析了硬件和协议栈，找到了传感器节点能耗的主要原因，并构建了无线传输能耗所需的数学模型。本文从原有的压缩感知方法出发，主要研究无线传感器网络中的数据采集方法和数据重构方法。最后，在压缩感知技术的支持下，我们将接收器、转发器等作为硬件结构的一部分，同时通过交互式教学软件的设计，即压缩感知网关、数据访问服务等。 ,
