The Research Of Perceptual Plat-Form In Smart Classroom

With the rapid development of information technology and education theory,many countries around the world advocate the deep integration of information technology and classroom,so as to build a new learning environment to improve the teaching effect.The traditional multimedia classroom is gradually developing towards the smart classroom with the intelligent characteristics of interaction and perception.In this paper,we will study the smart classroom perception platform,make full use of mobile devices and iBeacon technology,and connect the teachers,classrooms and students closely together to improve the interactive experience in the smart classroom.First of all,the paper analyzes the status quo of the interaction in smart classroom,and the key problem is the indoor positioning and identity recognition.According to the present BYOD(Bring Your Own Device,comes with the device)situation and develop-ment of indoor positioning technology,using iBeacon technology which based on BLE4.0 to solve the indoor location identification,and using mobile terminal to identify personal identity.Secondly,according to the user demand of the smart classroom system,the smart classroom perception platform model is proposed.The model structure is divided into two parts:the perception layer and the application layer.Among them,the perception layer Beacon Map sensor network is composed of iBeacon equipment,to provide location ser-vices,after the students entered the smart classroom,connected to the Beacon Map sensor network through the handheld mobile terminal,using iBeacon positioning algorithm can obtain real-time location information.The application layer is built on the basis of the per-ception layer location service,and provides the intelligent service for the classroom ac-cording to the position information.Finally,on the basis of the basic model of the sensing platform,taking the intelligent sign on service as an example,the whole design and implementation are completed from the server,the mobile client and the notice board.The server provides service interface,login,registration,information query and other functions of logic;the mobile APP is used for students to complete the automatic sign on and sign off and other teaching environment;notice board is the classroom information terminal,used to display the real-time changes of teaching activities,the voice broadcast mode to prompt students to leave early,late be-havior.On this basis,through the function test and performance test,the effectiveness of the platform is verified.The biggest characteristic of the perception platform is:using the mobile devices and iBeacon technology,realizes the real-time position information acquisition and identifica-tion of the teachers and students in the classroom,through the location information,ac-complish common teaching activities automatically and get personalized information.It has a certain inspiration to the innovation and development of smart classroom teaching mode.
