Abstract: This article aims at the current situation that the teaching of Internet of Things application system design course is complicated and the time is tense, which leads to the poor teaching and learning effect. It puts forward that combining the market demand and own reality, streamlining the course knowledge, supplemented by the hardware platform in teaching, focusing on PC application development, the use of task-driven teaching of teaching ideas and methods, and gives a task-driven teaching ideas.
Key words: Internet of Things applications system; task-driven;Project driven;teaching reform; teaching methods
一个完整的物联网应用系统分为三个层次:感知层、网络层和应用层,感知层主要用于识别物体和采集信息,核心的技术即传感器技术和RFID技术,涉及的自动感知设备主要有RFID标签和读写器、传感器;网络层主要将感知层获取的信息进行传输,核心技术有网络通信技术;应用层主要面向用户,是物联网与用户的接口,是各种面向企业行业的智能应用,一般用于展示感知层获取的信息或者对底层设备进行远程启动和控制,核心技术涉及各种软件开发技术,比如Android应用开发、javaweb开发技术等,其中以面向移动终端的安卓应用系统最为普遍[1-2]。从数据感知、传输处理再到控制,完成一个物联网应用系统所需要的知识涉及电子、通信、计算机等多个学科,因此要学习的专业课程和内容远远多于其他专业,要在有限的学时内,使学生掌握物联网系统概念和理论知识,具有物联网应用开发能力,其难度可以想象,《物联网应用系统设计》课程正是承载着这一任务,对于学生专业知识和技能水平的综合应用和提高意义重大。……
