proposal door locking security system

Abstract
The main aim of this project and implimentation is to provide security at homes, offices etc. The system automatically locks the door as soon as it receives a predefined message from the user.
This project and implimentation uses the wireless communication, GSM. To receive the messages from the user mobile, we need a GSM modem. This modem will be interfaced to the microcontroller through serial interface. A modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
If the user is somewhere far from the main door and he wants to close the main door right from the place he is standing, he has to send a predefined message to the modem. The controlling unit will be fixed at the main door. The controlling unit contains the microcontroller and the GSM modem interfaced to it. The microcontroller continuously checks whether it has received any message from the modem.
When the user sends the predefined message to the modem, the modem receives the message and intimates the same to the microcontroller. The microcontroller retrieves this message from the modem by issuing certain AT and T commands to the modem. Thus, after receiving the message from the modem, the microcontroller automatically closes the door by rotating the stepper motor fixed to the door. This will be done perfectly without the involvement of any human.

This project and implimentation uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step d

 

1. Introduction

1. Introduction
Security is prime concern in our day-to-day life. Everyone wants to be as much as secure as to be possible. An access control systems forms a vital link in a security chain. The micro controller based digital lock presented here is an access control system that allows only authorized persons to access a restricted area. This system is best suitable for corporate offices, ATMs and home security.
The system comprises a small electronic unit with a numeric keypad, which infixed outside the entry door to control a solenoid-operated lock with the help of a stepper motor. When an authorized person enters predetermined user ID and password
via the keypad, the stepper motor is operated for a limited time to unlatch the solenoid-operated lock so the door can be open. At the end of preset delay, the stepper motor is operated in reverse direction and the door gets locked again. When the code has been incorrectly entered three times in a row, the code lock will switch to block mode. This function thwarts any attempt by ‘hackers’ to quickly try a large number of codes in a sequence. If the user forgets his password, the code lock can be accessed by a unique 10 digit administrator password. The secret code can be changed any time after entering the current code (Master code).

2) Objective

The project and implimentation intends to interface the microcontroller with the GSM modem and start/stop the vehicle engine by sending the predefined messages from the mobile to the controlling unit. The project and implimentation uses the GSM technology and Embedded Systems to design this application. The main objective of this project and implimentation is to design a system that continuously checks the messages if any, received from the user mobile and change the status of the engine as per the message received from the mobile through the modem.
This project and implimentation is a device that collects data from the mobile, codes the data into a format that can be understood by the controlling section. This system controls the engine motor as per the message received from the mobile.
The objective of the project and implimentation is to develop a microcontroller based control system. It consists of a GSM modem, microcontroller, the interfacing unit to allow the communication between the microcontroller and mobile and the required circuitry.
