Design of Classroom Wireless Fire Monitoring and Alarm System Based on CC2530

Abstract

In the last decade, information technology has gained a rapid development in the education industry. Particularly on the university campuses, information infrastructure is becoming more common and classrooms are becoming more modern. The increase of information infrastructure, however, while creating a comfortable teaching environment for students, it also brings more security risks. Thus, the safety of the classroom has also attracted more attention. Most classroom fire monitoring systems currently used are part of the traditional wired fire monitoring system. It is susceptible to a variety of objective factors, such as aging circuits, and some problems such as failure of the fire detection system. To address these challenges, this paper presents a CC2530 based classroom wireless fire monitoring system, and designs a fire monitoring system suitable for classrooms. The hardware part monitors the temperature and smoke concentration in the classroom through sensors to determine whether a fire occurs. The software part uses the ZigBee protocol stack Z-Stuck to send the monitored data to the monitoring center, enabling staff to monitor the classroom environment in real time. Experimental results show that the combined software and hardware system are well adapted to a modern classroom with many electrical devices and dense personnel. At the same time, the system possesses the characteristic of real-time data collection, high positioning accuracy and large transmission rate, which can meet the standards and requirements in practical applications.
