摘 要
室内防盗检测系统作为一种新型的电子防盗设备广泛应用于家庭住宅区。目前市面上所拥有的家庭电子防盗报警器，只能用于单一的住宅，不利于统一管理，而且也不能满足现代住宅区的发展要求，所以很有必要对家庭电子防盗器进一步完善和提高。
本文提出了一种基于单片机信号处理技术的防盗检测器的软硬件设计方法。应用该方法设计的系统在反应速度、误报率、漏报率以及抗干扰能力方面都具有较好性能。本系统利用热释电红外传感器的红外辐射与红外探测的原理，设计的新型探测器，测量范围广, 响应速度快, 灵敏度高，抗干扰能力强，安全可靠 。并采用单片机89C51作为人体探测系统的核心，以热释电红外线为数据采集部件，经过比较放大之后，输入单片机进行数据判断及处理。当检测到有被测物体进入测量范围时，系统自动发出声光报警信号，等待一段延迟时间后自动消除报警信号，并可手动解除报警信号。当有主人在家系统无需报警时,可开启楼道灯控制系统，即传感器探测到有人经过时照明灯亮,等待一段延迟时间后自动熄灭,并可手动来控制延迟时间的长短。系统的另外一个功能是检测人数及最大容量人数控制，当探测头探测到有人经过时,系统自动计数加一，并可以通过键盘控制最大容量人数，如果探测到的人数超过最大容量人数时则发出自动报警信号，并通过LED显示检测到的人数与最大容量报警人数。系统使用单片机与PC机通信原理，把采集到的数据传输给计算机统一处理。
