Abstract
The invention discloses an infrared anti-theft system based on a single-chip microcomputer. The infrared anti-theft system is composed of a pyroelectric infrared-sensing probe circuit, an amplifying circuit, a reset circuit, a single-chip microcomputer, an alarm circuit and an LED light-emitting display unit. The pyroelectric infrared-sensing probe circuit and the amplifying circuit are connected; and the single-chip microcomputer is connected with the amplifying circuit, the reset circuit, the alarm circuit, and the LED light-emitting display unit. And the single-chip microcomputer employs an AT89C51 chip. According to the infrared anti-theft system disclosed by the invention, the AT89C51 single-chip microcomputer is used as a working processor core and the pyroelectric infrared sensor is connected externally; and the pyroelectric infrared sensor being a novel passive infrared detection device is capable of detecting infrared radiation sent out by the human body in a non-contact manner and converting the infrared radiation into a corresponding electric signal for outputting. And the interference from the infrared light except the human body radiation wavelength and visible light can be suppressed effectively.
Description
Technical field
The present invention relates to a kind of burglary-resisting system, more particularly to a kind of SCM Based infrared theft system.
