摘 要
在社会信息化进程日益发展的今天,信息技术已渗透到人类生存、活动的各个领域[1],人们的现代生活、工作、对居住和办公的建筑环境不仅要求舒适健康、安全可靠、高效便利,同时还要适应信息化社会运用科技手段和设备的要求。因此,将智能化引入宿舍已成为一种趋势,并且在智能化宿舍管理系统中对防火防盗报警进行监控已经成为民用建筑领域向信息化和网络化发展的一个重要组成部分。
本系统采用宏晶公司的STC89C52单片机作为主控制器,被监控宿舍利用热释电传感器、烟雾传感器配以蜂鸣器和LED实现人体检测、烟雾检测和声光报警功能。选择4*4矩阵键盘输入密码实现解警功能。用光电开关记录宿舍内人员的进出情况,选用ISD4002语音电路实现语音提示功能,并用nRF905无线传输实现异地监控,能够随时查看当前或最近几天的宿舍安防情况。利用无线射频数据传输和串口异步通讯实现网络监控,选用声磁防盗系统检测贵重物品的进出情况。
经过测试,本系统完成了课题的各项要求。宿舍节点控制器接收信号实现声光提示和液晶显示,并通过无线通讯模块传送给监控机实现异地监控,一部监控机可以远程监控多个宿舍,有利于学生宿舍的安全管理。

Intelligent security fire alarm system in dormitory
Abstract
In the process of increasing development of information society of today, information technology has infiltrated into human existence and activities of the various areas in the construction sector, people's modern life, working on residential and office building requires not only comfortable and healthy environment, safe, reliable, efficient and convenient, but also for the Information Society to use technology tools and equipment. Therefore, intelligence has become a trend into quarters in the intelligent management system for monitoring anti-theft alarm of fire, this has become the civil construction field to the development of information and networking is an important component.
The system uses macro crystal company STC89C52 as the master controller,By monitoring dormitory pyroelectricity sensor, smoke sensor buzzer and LED to realize human testing, smoke detection audible and visual alarm function, Choose 4 * 4 matrix keyboard input password system's warnings, Using photoelectric switch records in the dormitory and staff; Choose ISD4002 speech hint lock function realization circuit, NRF905 and realize remote monitoring, Using radio frequency transmission and asynchronous communication network monitoring, Choose sound magnetic security system in detecting the valuables.
