Abstract:

In order to strengthen monitoring and management of the dormitory in the university,a design scheme of the security monitoring system based on ZigBee and 3G technology has been proposed,which realizes the real-time synchronization of the dormitory environment data upload and the data reception in the background monitoring center.The system is designed according to the theoretical model of Internet of things,which includes three layers:the perception layer,the network layer and the application layer.Specifically,the perception layer uses ZigBee and sensor technology to construct a wireless sensor network to collect the dormitory environment data;the network layer uses ARM-3G embedded gateway to upload the perceptual layer data to the background server;and the application layer uses PC client and mobile application to form the background monitoring center,which is responsible for data monitoring and management.The simulation tests show that the host computer software can receive data in real-time,and the staff can make the corresponding processing according to the data.At the same time,the test results show the system runs stably and can meet the expected design requirements.
