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.
