苏州科技学院天平学院本科生毕业设计（论文） Page3 苏州科技学院本科生毕业设计（论文） 1 基于单片机的红外报警监控系统设计 摘 要 伴随着经济的飞快发展，科学技术的发展速度令人侧目。随着人民生活水平日趋提高，大家对自己的个人财产的保护意识也是越来越重，因此，越来越多的家庭都安装了报警监控系统来保护自己的私有财产和人身安全。 在众多的报警系统当作，红外报警监控系统凭借它很高的稳定性和可靠性赢得了广泛的市场。本设计采用了STC89C52单片机，把STC89C52作为了这个系统的核心来进行系统的设计，由于人的体温恒定在37度左右，所以人体会发射出特定波长的红外线，这种红外线通过被HC-SR501人体红外传感器的检测后，红外线信号就会转化成为电压信号，通过单片机对信号进行经过一系列的处理以后，就会驱动控制声光报警电路进行报警。本设计使用HC-SR501人体感应模块来进行探测。HC-SR501灵敏度高、可靠性强、安装简单方便而且非常隐蔽，不容易人被发现。 本文设计完成的红外报警监控系统，比普通的报警监控系统抗干扰性能更好、安装更方便、成本低廉,是现代家庭防盗报警的最佳选择。 关键词 STC89C52；报警电路；HC-SR501模块；晶体振荡器 The design and implementation of Infrared alarm monitoring system based on SCM Abstract Along with the?fast?development of economy,?science and technologydevelopment speed is?surprising.?With the peoples living standards?graduallyimprove,?everyone to his?personal property?protection consciousness is?more and more heavy,?therefore,?more and more families?have installed?alarm monitoring?system to?the protection of private property and the?peoples ownpersonal safety.
