Design And Implementation Of Student Attendance System Based On Bluetooth Communication

2013 is known as "the first year of wisdom education in China".All kinds of smart educational products are widely used in teaching,educational research and educational management,which promotes the development of modern education.As a sub-module of education management,student attendance is also an important work in the construction of school spirit.Establishing a perfect attendance system plays an important role in promoting students' enthusiasm in school,ensuring teaching order and improving the quality of student training.The traditional attendance methods such as teacher roll-call and school leaders' inspection are not only inefficient,but also consume lots of time and manpower.Modern information technology is urgently needed to change them.Aiming at the needs of smart campus management,the CC2460 Bluetooth microcontroller developed by Texas instruments is adopted to realize a student attendance system.According to the positive correlation between iBeacon RSSI and distance,a single and double threshold attendance status determination scheme is designed.The student sends the broadcast through the attendance card,and then the transit server forwards the attendance information to the background server.The background server performs the persistence of the attendance information and sends the attendance information to the message push component,which finally pushes the attendance information to students' parents.This paper firstly introduces the concept of smart education and relevant research,and then makes a comparative analysis of the current main attendance checking methods.Aiming at the advantages of low power consumption,short distance communication and low cost,Bluetooth is finally selected as the implementation method of student attendance checking.The background server adopts Spring5 architecture to provide batch processing function of attendance information.JAVA NIO is used to implement a simple message push component.The page of PC browser adopts Bootstrap architecture for page layout and interacts with the background through AJAX to achieve the effect of local refresh.The hot standby mechanism is adopted to avoid single point of failure.Through testing,the student attendance system can significantly improve the efficiency of attendance,the background business processing function is complete and the real-time information push function is good.
