单片机红外报警器 19

摘  要 电子电器在飞速发展的同时，人民的生活质量有了很大提高。各种高档家电产品和贵重物品为许多家庭所拥有。然而一些不法分子也是越来越多。这点就是看到了大部分人防盗意识还不够强.造成偷盗现象屡见不鲜。因此，越来越多的居民家庭对财产安全问题十分担忧。 实时报警器的正是在这种环境下诞生的，但是市场上的报警器大部分都是用于一些大公司财政机构，价格昂贵不适合一般家庭使用。设计和生产一种价廉、性能灵敏可靠的防盗报警器，必将在防盗和保证财产安全方面发挥更加有效的作用。由于红外线是不见光，有很强的隐蔽性和保密性，因此在防盗、警戒等安保装置中得到了广泛的应用，此外，在电子防盗、人体探测等领域中，热释电红外探测器也以其价格低廉、技术性能稳定等特点而受到广大用户和专业人士的欢迎。 本系统就是基于高性能处理器单片机和无线传感器等知识设计的可以自动检测到人的非法侵入，并声光报警，同时还可以通过无线将报警信号传给远程的户主，在远程监控室内的安全状况。系统结构紧凑，具有很好的使用价值。                   关键字： 单片机，红外报警，无线监控     Abstract Electronic appliances in rapid development at the same time, the quality of people's life has been improved a lot. All kinds of high-grade electrical appliances product and valuables for many families have. However, some outlaws is more and more. This is to see the most people anti-theft consciousness quite good enough. The phenomenon caused by stealing creditors. Therefore, more and more households worried of property safety problems. Real-time alarm is born in this environment, but the market for the alarm is mostly a few big companies financial institution, expensive is not suitable for general family use. Design and produce a low price and performance sensitive and reliable and alarm system, will in the guard against theft and ensure the property security play more effective action. Due to the infrared light is missing, and have a strong concealment and confidentiality, so in security, alert security devices such as has been widely applied in electronic security, in addition, human exploration, etc, and pyroelectric infrared detector with its low prices, technical stable performance by the masses of users and characteristic and professionals welcome. This system is based on high-performance processor SCM and wireless sensor etc knowledge design can automatically detect to people and trespassed acousto-optic alarm, also can through wireless will alarm signal to remote householder, in remote monitoring indoor safety conditions. System structure is compact, has the very good use value.       Key word:  microcontroller, infrared alarm, wireless monitoring   目录   摘  要... 1 Abstract 2 一、引言... 3 1.1课题研究的意义... 3 1.2本系统拟设计的拟解决的问题... 3 1.3系统概述：... 3 二、系统主要芯片介绍... 4 2.1 51单片机简介及系统最小系统设计... 4 2.2红外传感器原理及选型... 12 2.2.1热释电传感器的工作原理... 12 2.2.2 红外传感器的选型... 14 2.3 BISS0001信号调理芯片... 14 2.4 无线芯片PT2262，2272介绍... 16 三、硬件设计分析... 17 3.1单片机最小系统设计... 17 3.2透镜和红外传感器部分... 18 3.3信号调理电路... 19 3.4 无线发射与接收... 22 3.5扬声器控制电路... 23 四、软件设计... 24 五、结论... 26 致   谢... 27 参考文献... 28 附录一、整体硬件电路图... 29 附录二、程序代码：... 30 [资料来源：http://THINK58.com]
