摘要

 随着社会的进步,人们对家居生活安全性的要求也越来越高,各种防盗探测器应运而生。由于红外线是不可见光,有很强的隐蔽性和保密性,因而在防盗、警戒等安保装置中得到了广泛的应用。
 本系统利用红外线进行布防的防盗报警系统，此报警系统利用多谐振荡器作为红外线发射器的驱动电路，驱动红外发射管，向布防区内发射红外线。接受端则利用专用的红外线接收器对发射的红外线信号进行接受，经过放大电路进行信号放大后再进行整形，以CD4011作为逻辑处理器控制报警电路及复位电路，电路中设有报警信号锁定功能，即使现场的入侵人员走开，报警电路也将一直报警，直到人为解除后方能取消报警。

ABSTRACT

 Along with the progress of the society, the people of household life safety requirements are increasingly high, various anti-theft detector. Because there is no light, infrared and confidentiality of concealment, anti-theft security devices, alert etc widely application.
 According to the present situation of the application of alarm was designed using infrared on an anti-theft alarm system, the protection of the alarm system harmonic oscillator as infrared transmitters driving circuit, drive infrared tubes, to the protection zone of infrared emission. Use special infrared proportional to launch the infrared signal receiver to accept, amplified circuit amplification after plastic, CD4011 as logical circuit and control circuit, reset the alarm circuit alarm signal lock function, if the site, alarm circuit intrusion personnel away will always alarm, until the people lifted rear can cancel the alarm.
 This paper also introduces the concept, infrared detector, definition and classification. Introduces various common infrared alarm, analyses the working principle of Bijection infrared alarm. For infrared Bijection infrared alarm proceed modular analysis were introduced, including, Bijection infrared alarm is the  transmission and reception of the part of the design and implementation.
