摘 要

课题针对目前社区安全越来越受到人们的关注，尤其是居室的安全和报警更与千家万户相关，提出一种通过电话网构成的社区安防系统。其终端是社区服务中心，前端是居室安全报警系统。安全报警系统的性能包括当有陌生人的非法闯入、室内有火情、室内有毒气体超标和室内漏水跑水情况发生时发出报警。传感器对居室进行实时检测，当发现有异常状况后，单片机就执行进行报警程序。报警情况分两种情况进行，当主人在居室时，可通过铃声报警，主人根据提示去实地检查后决定自行处理还是打电话报警求助。另一种情况是主人不在居室时，则由单片机进行模拟摘机和拨号，接通后由单片机启动事先录制在语音芯片的语音进行报警。首先报告楼号、楼门号、房号，然后报告发生情况的具体地点。这样系统的费用不多，安装施工量不大，既可人工报警又可自动报警，可以满足居室安全的要求。

The Application of MCU for Security Alarm System of Home
              Abstract

Lesson a safety on aiming at current community safety more and more ising concern by people, particularly is living quarters with report to the police and even is ten thousand with thousand related, put forward a kind of community that pass the telephone net constitute the peaceful defending the system. Its terminal is a community service center, the head is a living quarters safety to report to the police the system. The safety reports to the police the function of the system includes to be to have the stranger and illegal intruding into, indoors contain super mark in poisonous air in feeling, indoors in fire is leaking to run the water circumstance occurrence with indoors send out to report to the police. Spread to feel the machine proceeds to the living quarters the solid hour examines, being the detection have the abnormality condition the empress, microcontroller carry out the proceeding report to the police the procedure. Reporting to the police the circumstance divides two kinds of circumstances proceeds, playing the host at living quarters, can pass the bell ring report to the police, host according to decide to deal with by oneself after hinting the on-the-spot check or make a phone call to report to the police to ask for help. Another circumstance is host not at living quarters, then be proceeded by microcontroller the emulation take off the machine with stir the number, being started by microcontroller to record in advance the speech in microcontrol chip proceed to report to the police. Report the floor number, floor a number, building number first, then the concrete location of the report occurrence circumstance. Like this the expenses of the system is not much, installing the construction measures not very, since can the artificial report to the police to can report to the police automatically again, can satisfy the safe request in living quarters.
