智能家居安防及报警系统设计
摘 要
随着科技的进步和社会的发展,人们对于家居安防系统的要求越来越高。鉴于此，
本文在现有家居安防系统的基础上设计了一种以AT89S52单片机为控制核心的无线遥控报警的智能家居安防及报警系统。该文在绪论中介绍了智能家居安防及报警系统在国内外的研究现状和进展,并论述了包括系统结构、工作原理以及该系统的硬件电路设计和软件设计。该系统通过连接各种传感器来实现对家居安防的控制和无线远程报警, 它集防火、防盗和防煤气泄漏三防于一体, 和市面上现有的家居安防系统相比, 更实用可靠，性价比更高。

Abstract
With the progress of science and technology and the development of the society, people more and more high to the requirement of home security systems. In view of this, on the basis to the existing home security system, this paper designed an intelligent home security and alarm system of wireless remote control alarm which based on AT89C52 microcomputer as a control core. This paper introduced research status and progress of the intelligent home security and alarm systems at home and abroad in the introduction and discussed include system structure, working principle and hardware circuit design and software design of the system. The system would be achieve the goal by connecting all kinds of sensors to get remote control and wireless remote control alarm, it sets fire, theft and anti-gas leak in one of three defenses. Compared with the existing home security systems on the market, the system I designed are more practical, reliable and more cost-effective.
Key words: home security and alarm system; microcomputer; remote control
