1、 I 基于单片机的主被动红外线防盗系统设计与制作基于单片机的主被动红外线防盗系统设计与制作 摘要：摘要：随着国民经济的发展,社会安全保障的需要,电子报警这门综合技术正在不断地发 展。与同时，红外技术已经成为先进科学技术的重要组成部分，由于红外线是不可见光， 因此用它进行红外探测监控，具有良好的隐蔽性，白天和黑夜均能使用，而且其抗干扰 能力强。防盗报警系统利用单片机控制技术，自动探测发生在布防监测区域内的侵入行 为，产生报警信号。本设计正是基于此，设计了主动式、被动式红外防盗报警系统。 本文系统地介绍了红外热释传感器、菲涅尔透镜的构成原理。利用以上原理设计了红 外防盗系统，其作用是检测有没有红外
2、源靠近该系统。同时也介绍了红外对管，即通过红外 线的发射和接收构成了主动式的红外防盗系统，其作用是检测有无遮蔽物遮蔽该红外探头。 基于单片机的红外线防盗系统是将红外线防盗原理结合单片机原理构成的一个新型 功能系统。在该系统中，红外传感器以及红外对管检测环境，如有异常传送给单片机， 通过单片机进行实时处理，发出报警信号。同时本系统还附加了时钟显示，温度显示等 功能。本文还细致地描述了利用单片机控制的硬件组成、软件流程、程序设计及调试。 关键词：关键词：红外热释传感器 菲涅尔透镜 单片机 声光报警 II Based on passive infrared alarm system design a
