The Design and Implementation of a teacher-student interaction system based on ZigBee and RFID

 

Based on analysis of features of ZigBee Wireless sensor networks and RFID technology. From the perspective of improving teaching methods, combining teaching practices, a teacher-student interaction system based on ZigBee and RFID technology was designed and implemented for the application of actual teaching. Results show that the system achieved the basic functions of a teacher-student interaction system. The ZigBee technology is the standard wireless network protocol stack for low-rate sensor and control network design, is the suitable standard for wireless sensor network. ZigBee wireless sensor network is based on the ZigBee technology. It has great application potential. Radio Frequency Identification, RFID is the use of radio frequency signals through space coupling (alternating magnetic field or electromagnetic field) to achieve non-contact transmission of information through the message to the purpose of automatic identification technology. The unique function of RFID is to mark anything or person of the real world, in the virtual world of network; it has three functions as "tag”, “address number" and "sensing".

 

 

 

                                                       The teacher-student interaction system consists of RFID systems with ZigBee subsystems, can enhance the learning interaction between students and teachers,. Students may also rely on this system to effectively communicate and interact with teachers, to unfamiliar places for learning and ask questions at any time, to avoid face to face embarrassing questions or omission may be key Each elective course students are assigned to a student tag, every seat in the class room table with a simple reader (Reader) subsystem, after students enter the classroom, the table reader subsystem can automatically sense and read the student tag, then the reader will send the information via ZigBee wireless to the podium of the main system

 

                                                       Students subsystem is equipped with 3 buttons and LEDs, students can push the yes or no button on the subsystem, (to know or do not know) to answer teachers’ questions, by ZigBee wireless, the answer back to the main system on the podium, the main system with a display subsystem to display the corresponding keyboard keys and control, student status and location can be displayed through the display, teachers can monitor the students’ real-time understanding of the course and to grasp the situation, give supplement according to the situation, through the button, to call a student, each subsystem (for example: A ~ Z) corresponds to the buttons on the main system A ~ Z). The subsystem table lamp (LED) of the students called will light up or flash, until the student presses the yes button.
