Title Intelligent photoelectric detection and intelligent control of the microcontroller for security windows.
Abstract
This article inspect and research the background and status of the home burglar alarm system, on the basis of which designed an infrared detection and intelligent control of SCM as the core of home burglar alarm system about security window and designed the hardware circuit and software programs of the system..
The system consists of a SCM system which is formed by a single-chip microcontroller AT89S52 system as the core, combined with infrared sensors, optical alarm display circuit and GSM SMS module. The infrared sensor uses light detector as the core components, after the issued infrared was obstruction, sends a signal to the microcontroller. After the microcontroller processes the signal, the light alarm circuit sends a alarm signal, at the same time the microcontroller sends alarm messages to security personnel and the owner’ hands via the GSM module.
The system used a modular design and integrated systems and external key human-computer interaction engineering, using C programming language, which has good stability, reliable operation, low cost, convenient installation and easy operation, can achieve the goal of intelligent burglar alarm.
Keywords: home burglar alarm system infrared sensor photoelectric detection SCM intelligent control
