摘　　要：针对目前多数课程学习以纸本教材为主,难以形成互动学习模式等问题,开发了基于物联网的数字化学习平台。通过隐形二维码嵌入印刷和光学识读,2.4G和3G无线通信,创设了立体化互动教学环境,实现了教材、教具等与本地及互联网的多媒体资源的互联。通过教学服务系统记录互动痕迹,为教学统计分析、优化教学手段提供了数据支持。文章对系统研发涉及隐形二维码编译码及优化、点对多点无线通信、互动教学点播等关键技术的实现进行了详细论述。平台的推广应用,将有效提高学习效率和教学质量。Aiming at the problem existing in most course learning that is given primarily of printed textbooks and difficult to form the in teractive learning mode, a digital learning platform based on internet of things is developed. Through contact 2D code embedded printing and optical reader, 2.4 G and 3 G wireless communication, a three-dimensional interactive teaching environment is created, which reali zes the teaching materials and teaching aids interconnected with local and internet multimedia resources. The interactive trace which is re corded with the teaching service system, provides data support for teaching statistics analysis and the optimization of teaching means. It details contact 2D code codec and optimization, point to-multipoint wireless communication, interactive teaching environment and other key techniques of the system. The popularization and application of the platform will improve the learning efficiency and teaching quali- ty.
