Design of Intelligent Anti Theft and Fire Control System for Student Dormitory

Abstract:In order to ensure the safety of students dormitory, this paper take AT89S51 monolithic integrated circuit as the core design of intelligent fire alarm control system. The system is composed of a signal acquisition unit, a signal transmission unit, control unit and alarm module unit can automatically monitor the dormitory security, such as a fire, burglary and other abnormal situations can immediately send out alarm and help information. The system has the advantages of low cost, suitable for student dormitories, more secure and more secure. Report to the police immediately in case of abnormal conditions. After testing, the system has completed the requirements of the subject. Compared with the traditional security system, the system is more easy to maintain and realize non contact, high reliability and low cost of hardware and the advantages of the application of a variety of places.
