摘 要
本系统根据大赛设计要求以 AT89C52 单片机为控制核心,自行设计了一套宿舍智能防
盗防火报警系统。在该系统中以 AT89C52 单片机及无线收发模块组成异地监控站,对宿舍
进行安防、火灾的实时监控,并配备了异地解警功能;在宿舍内部以 AT89C52 单片机及光
电开关实现宿舍内人员的进出情况及人数记录并在无人时提示锁门。此外,该系统还可以
实现对宿舍安防情况的记录以及对贵重物品的检测功能,同时该系统还可以在出现警报时
给相应的报警中心拨打电话。

Abstract
In this system , we use microcontroller –AT89C52 as the control unit, to
design a wisdom system of re prevention and steal prevention for
dormitories . We use microcontroller –AT89C52 and wireless module for
shouting and receiving to monitort the secutity and re of the dormitories and
we can use the microcontroller to relief the alarm; in the dormitories, we use
microcontroller –AT89C52 and infrared switch to realize the amount of people
in dormitories and it can prompt locking the door when there is no people in
the dormitory; Besides,the system can record the security situation an check
the valuable things, it can dial the appropriate telephone number when the
alarm appears.
