Design of a Smart Classroom Broadcasting System Based on WSN

Abstract:

This paper presents a smart classroom broadcasting system using WSN technology. Different from other online broadcasting systems, it adopted ZigBee module JN5148 as microcontroller. Text or audio files were sent to the radio terminal in network data packets through the coordinator. It has achieved wireless transmission and intelligent release of personalized voice and ringtone, real-time control of fire alarm and security monitoring . Test results show that ZigBee network operates stably, the broadcasting system embeded ZigBee techology does not need complex wiring installation .The whole system is easy to maintain. It also meets the the application requirements for current broadcast technology .
