Research On The Internet Of Things Classroom Management System Based On JN5148

With the expansion of university enrollment,the utilization of teaching buildings are gradually increasing,the use of classrooms also shows a diversity of content and time flexibility,and the teaching environment is gradually becoming more networked and intelligent.But there are many deficiencies in traditional classroom management system.Firstly,all classrooms receive the same bell call regardless of whether they have a lesson,which will disturb students who are taking exams or studying.Secondly,the sound of the traditional ring is loud and ear-piercing,it is not the ideal way to prompt the time.Thirdly,students can`t receive the individual activity status of classrooms.They spend too much time on searching free classroom which may disturb students who are attending class.In addition,the traditional Fire Alarm System only achieves simple alarm function,it lacks the location of incident and it can`t give more escaped routes information when the emergencies happen.There are always too many devices in teaching buildings connected with lots of wires,which are too difficult to maintain.With the development of the Internet of thing,domestic scholars have invented some intelligent classroom management systems,but they only solved one-sided problems.This paper designs a classroom management system which is based on Internet of Things.Bell management,voice management,fire warning and security functions are in this system.Each classroom is connected together by the wireless network of ZigBee,which can issue different information to the different classrooms.The system achieves humane ringing function and voice broadcast function by playing music and synthetic speech.Meanwhile,it uses the infrared sensor and the smoke sensor realizing security and fire alarm functions.When the fire and other anomalies occur,the system notifies teachers and students in classrooms by voice.The system applies the ZigBee coordinator to exchange data with server.Administrators employ the server software to achieve management of the individual or cluster classrooms.Students can save their time when looking for self-study classrooms by using the querying function of the software.The employ in the field showed that the system not only works stably,improves the automation level of classroom management,but also provides excellent convenience for managers,teachers and students.
