Intelligent Security System Report

Abstract

Security systems are needed for occupants' convenience and safety. This search, present advances a new design of intelligent security system design and implementation of a low cost, low power consumption, and GSM (global system for mobile communication) intelligent security system. The system is contains a GSM and kinds of wire security sensor that are ultrasound security sensor. The system components are easy installing. The system can response rapidly to alarm incidents by sending alarm message, and has a friendly user interface. In this search many devices are used; Ultrasonic radar is a sensor that used for motion detection it is range is (20 – 250) cm it sends out pulses of ultrasonic waves and measures the reflection off a moving object ;LCD (Liquid Crystal Display) screen, and it used for display the system mode; the microcontroller that used to control the previous devices is Atmega 16, through the program written by using basic compiler (BASCOM), and it's also controlled the PC program; host PC connect to the microcontroller ,it control webcam and GSM modem through the program written by ASM; webcam used the take a photo, it controlled by the PC; GSM (Global System for Mobile )modem, it's send a warring message to specific No. using AT commands , it's also controlled by the PC to send. Firstly concepts and the architecture of the system are explained, and then introduce some important hardware design and the key software design in detail. The experiments show a good alarming and control ability. Finally concluded the work, and discussed the future directions of the project.
