热释电红外人体探测报警设计论文.docVIP

摘 要 近年来，随着改革开放的深入发展，电子电器的飞速发展.人民的生活水平有了很大提高。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。ARM处理器具有运行速度快、功耗低、程序设计灵活、外围硬件资源丰富的优点，但其普通输入输出口的高低电平变化周期只能达到I微妙左右，不适合需要高速输入输出数据接口的系统。 热释电人体探测器可以作为报警器来使用。报警器这时正为人们解决了不少问题.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。价格高昂,一般人们难以接受。如果再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。Abstract In recent years, with the deepening of reform and opening up the development of the rapid development of electronic and electrical appliances. The peoples standard of living has been greatly improved. A variety of high-end home appliances and valuables owned by many families. However, some are also more and more lawless elements. That is why most people see the sense of security is not strong enough. Caused by theft common occurrences. Therefore, more and more families on the property are very concerned about security issues. ARM processor has the advantages of high running speed, low energy consumption, flexible program design, resourceful exterior hardware etc, but the cycle for its general GPIO voltage change is only about 1 microsecond, which is unsuitable for the system of high speed I/O data interface. Pyroelectric detector can be used as the body to use the alarm. Alarm at this time is for people to have solved some problems. But alarm on the market for most of them are some large financial institutions. The high price of general it is difficult to accept. If the design and manufacture of a cheap and reliable performance of sensitive anti-theft alarm, will guarantee the security and property security to play a more effective role. Key words： ARM processor, alarm目 录 引言 1 1 设计思路 1 2 系统组成 1 2.1 Philips LPC2138 1 2.2.1 结构概述 1 2.2.2 功能框图 3 2.2 LPC2138芯片最小系统板 5 2.3 辅助电路设计 5 2.3.1 HC-SR501热释电人体探测模块 5 2.3.2 BISS0001热释电处理芯片 8 3 电路设计 12 3.1硬件电路图 12 3.2 PCB图 13 4 软件设计 13 4.1 Protel软件介绍 13 4.2 源代码 16 5 布线、焊接和调试 16 5.1 布线 16 5.2 焊接 16 5.3 调试 17 6 结论 17 谢 辞 18 参考文献 20 附 录 21 引言 社会在不断进步，人类在不断追求，市场在不断变化，高科
