摘  要

随着社会科技的进步与市场经济的不断发展，建设智能化的社区逐步成为城市规划的一项重点目标。一个智能化的居民住宅在满足场所和空间要求的同时，还应保障居民居住的安全可靠。智能小区进入人们的视野，安防系统已经成为智能小区不可分割的部分。

传统的住宅安防系统不能对随时发生的情况进行全面、及时的了解和掌握，不能对意外情况迅速做出正确判断，和给出正确、快速的指挥和处理。针对传统住宅小区安防系统的缺点，设计了一种智能化的安防监控系统。本系统是以单片机为核心处理器，由红外、接近开关、烟雾和振动传感器对陌生人入侵、小区意外情况和发生火灾的情况进行检测，在LCD显示屏上显示蜂鸣器进行报警。通过对整个系统的仿真，基本实现了室内安全报警、电子巡更、周围安防、门禁等功能。

ABSTRACT

With the progress of social science and technology and the continuous development of market economy, building intelligent community has gradually become a key goal of urban planning. An intelligent residential housing in order to meet the requirements of places and space, but also to ensure the safety and reliability of residents living. Smart cell into people's field of vision, security system has become an integral part of the intelligent community.

The traditional residential security system can not be a comprehensive and timely understanding and grasp of the situation that occurs at any time, can not make a correct judgment on the unexpected situation quickly, and give a correct and rapid command and handling. In view of the shortcomings of the traditional residential security system, an intelligent security monitoring system is designed. The system is based on the microcontroller as the core processor, by infrared, proximity switch, smoke and vibration sensors to collect external signals, after the microcontroller processing, displayed on the LCD display, buzzer alarm. The software part adopts C language, analyzes and processes the data collected by the sensor, and realizes the function of monitoring the alarm. Through the simulation of the whole system, the functions of indoor safety alarm, electronic patrol, surrounding security, access control and so on are realized.
