基于单片机的智能防盗报警器

摘要：基于单片机控制的红外报警器以STC15F104E单片机和AT89S51单片机为核心，实现的原理是热释电红外传感器如果感应到入侵者的红外热辐射，就将其转换成电压信号，经电路放大、然后输出。检测器是利用红外人体检测探头检测预先设定好的范围内的情况，一旦有危险便向单片机发出信号，再经单片机处理，然后数码管显示出信号发出的具体范围并同时控制蜂鸣器发出警告声音。用红外线收发管进行检测，安装隐蔽，不易被发现；探测信号采用脉冲信号，节能且抗干扰。系统可以探测到一定范围内的人的闯入, 可以应用在安防范围比较确定的情况下。采用这种方法设计的防盗报警器具有误报率较低、安装和配置容易、成本低、能量消耗少、使用方便、成本廉价和探测效果好的优点，有着广阔的市场前景。

Based on single chip microcomputer

intelligent burglar alarm

Abstract: Based on the infrared alarm controlled by single chip microcomputer AT89S51 microcontroller and STC15F104E as the core, realize the principle of the pyroelectric infrared sensor of infrared

radiation which can sense the Infrared radiation of intruder and convert

it into a super low frequency signal, amplified by the circuit and output.

Detector is using infrared detection probe for detecting a prespecified

range. Once having the risk, it will send a signal to the microcontroller,

and be processed by the computer ,then digital tube shows the signal

issued by the specific scope and at the same time control buzzer warning

sound. The detection of the infrared transmitting and receiving tube is concealed and difficult to be found; the detection signal adopts pulse

signal, energy saving and anti jamming. The system can detect the

intrusion of people within a certain range, and can be used in the case of

the security scope of the comparison. T he alarm system which use this

method to design has advantages such as lower false alarm rate, easy installation and configuration, low cost, less energy consumption, convenient use, low cost detection and good effect, and has broad market prospects.
