Aiming at the time-consuming and energy-consuming situation of classroom sign-in in campus environment, a convenient,fast and low-cost classroom attendance was designed and implemented.In the system, people, events, times and places were connected by beacon device based on Bluetooth 4.0, which enabled students to sign in automatically at specified times and locations.B/S mode and C/S mode were used in this system.To research the indoor location technology based on Bluetooth 4.0,an indoor localization method was proposed which was easy to implement in practical application and in accordance with the requirement of localization accuracy.The experimental results showed that the classroom active signing system based on Bluetooth 4.0 could quickly and accurately complete the automatic check-in process,which was efficient and easy to manage.
