毕业设计（论文）报告题 目 红外人体报警器的设计系 别专 业班 级学生学 号指导老师2024 年 4 月红外线人体报警器的设计摘要：红外报警器大多数采纳国外的先进技术,其功能也非常先进。 其中包括被动式、热释电型红外报警器,也即是本文将讨论的产品。还有红外监控无线报警器,超声波防盗报警器,红外线防盗报警器,高灵敏红外报警器,触摸式延时防盗报警器, 触摸式防盗报警器,红外 报警器, 红外线声先报警器……报警器能探测人体发出的红外线，由红外线传感器、信号放大电路、电压比较器、延时电路和报警指示电路等组成。当人进入报警器的监视区域，即可发出报警信号，适用于家庭、办公室、仓库、实验室等比较重要场合防盗报警。概述了红外辐射的知识、热释电红外传感器的结构和工作原理。利用热释电红外传感器设计了一种被动式红外报警电路,分析了该电路的功能和工作原理。热释电红外传感器具有很多的优点,在防盗、警戒等装置中应用较广。关键词：被动式红外报警器、热释电红外（PIR）、传感器、热释电效应Design of infrared alarmAbstract ： Infrared alarm in most cases, the foreign advanced technology, and its function is very advanced. Including passive pyroelectric infrared alarm, that is, the products that are to be studied in this article. Infrared monitoring wireless alarm system, ultrasonic burglar alarm, infrared burglar alarm, high sensitivity infrared alarm, the touch delay burglar alarm, the Touch burglar alarm, infrared alarm, infrared sound the first alarm ......Detectors capable of detecting infrared rays emitted by the body, provided by the infrared sensor, the signal amplification circuit, a voltage comparator circuit and other components of the delay circuit and the alarm indication. When people enter the alarm monitoring area, you can send an alarm signal, suitable for homes, offices, warehouses, laboratories and other important occasions burglar alarm. An overview of the structure and working principle of the knowledge of infrared radiation, thermal pyroelectric infrared...
