具有机械自锁功能的窗户防盗报警系统设计

摘要

This paper puts forward a new kind of anti-theft alarm system for guarding windows .It is an infrared alarm system based on AT89S52 single chip microcomputer ,being of a mechanical self-locking function .The mechanical device is driven by a stepper motor .When sound and light alarm occurs ,the self-locking device blocks the motion of window open ,the window is fixed in the original position ,to achieve the double insurance of window anti-theft .%提出了一种新型窗户防盗报警系统，它是基于AT89S52单片机控制的红外线防盗报警系统，拥有在声光报警的同时阻止窗户打开的自锁机械装置部分。当有人闯入窗户附近区域时，红外线传输受到阻碍，此时系统的声光报警电路装置发出声光报警，同时触发步进电机驱动机械装置，将窗户锁定在原来的位置，阻止窗户的打开，从而实现了窗户防盗的双重保险。
