Active infrared anti-theft alarm

一种主动式红外防盗报警器

Abstract

The invention relates to an infrared anti-theft alarm, and discloses an active infrared anti-theft alarm. The active infrared anti-theft alarm comprises an infrared emission module, an infrared receiving module and a master control module, wherein both the infrared emission module and the infrared receiving module are electrically connected with the master control module; the infrared emission module can provide three levels of infrared pulse strength; the master control module is used for control according to the infrared pulse strength received by the infrared receiving module; the infrared emission module generally works at low-level strength; thus, the reliability of an infrared light emitting diode can be improved, and the service life of the infrared light emitting diode can be prolonged.
本发明涉及红外防盗报警器,公开了一种主动式红外防盗报警器,包括红外发射模块、红外接收模块以及主控模块,红外发射模块和红外接收模块均与主控模块电连接,红外发射模块可提供三档红外脉冲强度,由主控模块根据红外接收模块的接收到的红外脉冲强度来控制,红外发射模块通常工作在低档强度,因而可提高红外发光二极管的可靠性,延长其使用寿命。
