基于单片机的宿舍智能防火防盗报警系统的设计.doc

山东交通学院 2013届毕业生毕业论文（设计） 题目：宿舍智能防盗防火报警系统的设计 院(系)别 信息科学与电气工程学院 专 业 电气工程及其自动化 班 级 电气091 学 号 090819112 姓 名 王程 指导教师 潘为刚 二○一三年六月 原 创 声 明 论文作者(签字)： 日期： 年 月 日 摘 要 本设计是以凌阳SPCE061A为控制中心，实现对宿舍人员进出情况及人数的统计、贵重物品的检测以及宿舍火灾检测及报警功能。本系统设计并制作了一个主机，多个从机。从机由信号采集单元、信号传输单元、控制单元等组成，完成对宿舍火情、盗情等信息的采集、处理和发送功能。其中盗情检测由热释电红外传感器、光电开关和电磁信号感应技术MQ-2烟雾传感器和温度探测器为一体的复合式火灾探测器完成。当防盗探测器或防火探测器检测到险情的时候，向单片机发出中断申请，再由单片机控制报警电路，实现自动报警。主机通过无线传输器件nRF905接受从机信息，实现异地实时监控功能；该系统成本，应用于学生宿舍，能宿舍内的安异常情况时立即报警。 关键词:凌阳SPCE061A单片机, nRF905，热释电红外传感器，烟雾传感器，光电开关 Abstract The design is based on SPCE061A as the control center, to achieve the hostel staff out of the situation and statistics, as well as the detection of valuables dormitory fire detection and alarm functions. The system is designed and produced a host, multiple slaves. Slave by the signal acquisition unit, signal transmission unit, control unit and other components to complete the dormitory fire, Pirates of the situation and other information collection, processing and transmission capabilities. Pirates of the situation in which detection by the pyroelectric infrared sensors, photoelectric switches and electromagnetic signal sensing technology (electromagnetic Hall switch) completed and fire detection by the MQ-2 smoke sensors and temperature probes as one of the completed composite fire detectors . When the anti-theft detectors or fire detectors detect danger, when an interrupt request to the microcontroller, and then by the MCU control alarm circuit, automatic alarm. Information received from the host machine, to achieve real-time remote monitoring capabilities by nRF905; low cost of the system, used in student dormitories, can better accomplish dormitory security, in exceptional circumstances the police. After testing, the system
