宿舍智能防盗防火报警系统

An Intelligent Theft and Fire Alarm System Used in the Dormitory

设计了一种基于STC89C52RC单片机控制的智能防盗防火报警系统。通过单片机控制烟雾传感器、热释电红外传感器和光电门实现了火灾检测、人体检测、人员出入宿舍情况的检测,并将检测到的信号进行处理,实现了宿舍无人提示锁门以及出现警情进行声光报警的功能。报警后通过矩阵式键盘输入密码进行警报的解除,并在LCD1602液晶屏上实时显示检测情况和各种提示信息。利用单片机内置EEPROM存储数据实现掉电不丢失数据;通过无线模块实现了异地监控。

This paper designs an intelligent theft and fire alarm system based on single chip STC89C52RCW which through the single chip controls the smoke sensor, pyro-electric infrared sensors and photoelectric gate to realize fire detection, human body detection and personnel entry into and exit from the dormitory, and processes detected signal to realize door locking without prompt as well as sound and light alarm in alert situation. The alarm can be cancelled by giving a password in the matrix keyboard, and LCD1602 gives a realtime display of the detection and promptings. Data stored in the EEPROM of the single chip are used to avoid data loss in case of power break. Remote monitoring is realized through the wireless module.
