摘要
随着时代的不断进步,人们对环境的安全性提出更高的要求,很多小区都安装了智能报警系统,大大提高了小区的安全程度,、保安报警器基本都是以超声波、主动式红外发射/——,并将其转变为电压信号,同时,,也可以用于自动控制、接近开关、遥测等领域.
本系统采用了热释电红外传感器,它的制作简单、成本低、安装比较方便,而且防盗性能比较稳定,抗干扰能力强、灵敏度高、安全可靠。这种防盗器安装隐蔽,不易被盗贼发现,同时它的信号经过单片机系统处理后方便和PC机通信,便于多用户统一管理。本设计包括硬件和软件设计两个部分。硬件部分包括单片机控制电路、红外探头电路、驱动执行报警电路、LED控制电路等部分组成。处理器采用51系列单片机AT89C51,整个系统是在系统软件控制下工作的。
Pick to
Along with the advance of epoch, people to the environment safety put forward higher request, munity has installed intelligent alarm system, greatly improving munity safety degree, effectively guarantee the residents' personal property safety. The present domestic use of all kinds of security, security alarm basic are based on ultrasonic wave, active infrared transmitting/receiving and microwave technology as the foundation, etc. And here design of passive infrared alarm, the use of the American sensing element - pyroelectric infrared sensor. The pyroelectric infrared sensor to non-contact form detect the human body infrared radiation, and turned them into voltage signal, at the same time, it can identify the movement of the biological and other abiotic. Pyroelectric infrared sensor can be used for alarm device, can also use ?
This system USES a pyroelectric infrared sensor, its production is simple, the cost is low, the installation is more convenient, and anti-theft performance is stable, strong anti-jamming ability, high sensitivity, safe and reliable. This alarm installation concealed, is not easy to be thief found, at the same time it signal by SCM system after processing convenience and munication, facilitate multi-user unified management. This design including the design of hardware and software is two parts. Hardware part includes sin
