文档介绍：2015 届分类号: 单位代码: 13379 山东师范大学历山学院毕业论文(设计) 家庭安防报警系统设计姓名学号年级专业电子信息工程系(院) 电子信息与工程系指导教师 2015 年5月 24日 I 摘要该设计是采用 AT89C51 单片机实现的基于 GSM 短信模块的家庭安防报警系统。该系统主要由单片机 AT89C51 、HRH GSM Modem 短信模块、键盘显示电路、DS12887 实时时钟芯片、 315MHZ 调幅遥控器、传感器和其它基本外围电路组成,借助 GSM 移动网络,以最直观的中文短消息,直接把报警地点的情况反映到所设定的手机屏幕上。该系统采用 AT89C51 单片机作为主控制芯片,通过 HRH GSM Modem 来进行通信, 采用红外传感器进行检测,配备烟雾传感器和燃气泄漏传感器,实现防火、防燃气泄漏的作用。同时附加电路通过键盘显示电路来预设安防报警系统的电话号码, DS12887 实时时钟芯片对发生警情的时间进行记录和保证系统的可靠运行,315MHZ 调幅遥控器来实现用户对系统的布、撤防状态进行改变。硬件设计采用 Proteus 软件,完成了系统的键盘接口电路、时钟电路、电源电路、发射接收电路、传感器采集信号等模块的电路原理图的设计。软件设计采用 Keil 开发系统, 完成了程序模块规划及各个模块的设计与编程,实现了对信号处理过程的编程和调试。关键词:单片机; GSM 模块;传感器 II A BSTRACT This design is the use of AT89 C51 MCU to achieve The Family guard against theft and Alarm system Based on GSM Modem .It is made upof AT89 C51 MCU 、 HRH GSM Modem 、 keyboard display chip 、 DS12887 real-time clock chip 、 315MHZ remote control sensors and other basic peripheral circuits. It will display the alarm content in Chinese directly at your mobile screen, and it recurs to the GSM work. The System use AT89 C51 MCU as the control core chip, through the HRH GSM Modem munications,it adopted initiative infrared sensor to detect, the system equipped the smog sensor and leakiness sensor of gas and guarded against fire and gas leakiness. Meanwhile,additional circuit to default the telephone number of guard against theft and Alarm system by keyboard display chip, through DS12887 real-time clock chip to record the situation occurred in time for police and to ensure reliable operation of the system,315MHZ remote control to achieve the user to change the system ’s position . The hardware design using Proteus to achieve the circuit schematic diagram designs of the system keyboard interface circuit ,clock circuits,power circuits,transceiver circuits and the sensor signal acquisition module and soon. The software development system of Keil is used to design the software. And the procedure of the processing of signal has pleted and debugged essfully. Keywords : M
