SCOPE AND SIGNIFICANT

The door monitoring system is used to give high security protection for use in order to avoid from theft and easy monitoring once door have been broken.

On the basic idea of a door monitoring system are using PIC as main function to read and store the password enter by the user. The password should be 5 bits as a bit encryption. Upon entered password is true, then the magnetic lock will off therefore door can be open.  Besides, this project includes transmitter and receiver as a device to communicate between door and computer. Once the door being broken, the transmitter is active and sent signals to a receiver at the computer. From that signal, hostel warden easy to trace the theft room.The benefit of the final year project is to develop technical skills, knowledge and convert into a project that related study field. Fast thinking will produce positive feedback and able to solve the problem during completing the FYP session. Besides, this FYP will expose students from basic to the latest technology in electronics such as programming, basic electronic components and trouble shoot circuit. It is suitable with motto UniKL - BMI where knowledge can apply.

OBJECTIVES

LEARNING ABOUT THE OBJECTIVE

The main objective of this project is to study and develop the door security monitoring system that used for security and surveillance system. The purpose of this system is to increase security in hostel college and easily trace theft door (by giving specific location of the door). In doing FYP, the bulk of the work can be summarized as follows;



• To study how the function of the system works in dealing with electronic and mechanical parts.
• To design a door lock system which efficient, low cost and can be implemented to home and office security system.
• To develop a security system that able to increase security and give secure constantly.
• To apply the transmitting and receiving signal capable of dealing with security system which is suit the local industry needs.

PROJECT ANALYSIS

HARDWARE

  MICROCONTROLLER

This PIC has 40 pins. For power supply pins, VDD has connected to dc voltage which is range around 4V - 6V while VSS is connecting to ground. Then, clock pins osc1 and osc2 connected to oscillator (resonator). Function MCLR pin is to reset the PIC. The remains pins are input and output. 

The microcontroller acts like the brain of the door security monitoring system. The purpose of Microcontroller PIC16F877A which is manufactured by Microchip is to get the input from keypad and controlling transmitter. This chip is selected based on several reasons.

                        i. Its size is small and equipped with sufficient output ports without having to use a decoder or multiplexer.

                        ii. Its portability and low current consumption.

                        iii. It has ADC inside the chip itself which allow to converting the signal (analog) from transmitter into digital code

                        iv. It is a very simple but powerful microcontroller. Users would only need to learn 35 single word instructions in order to program the chip.

                        v. It can be programmed and reprogrammed easily (up to 10,000,000 cycles) using the universal programmer in robotics lab.

INTRODUCTION

PROJECT DESCRIPTION

Door security monitoring system is a system that designed as a problem solution usually for security system in college hostel. The problems are able be solved by this system are theft, trace location of the room (especially for hostel warden) and user manually setting the password (set and reset the password).The main problem with this project attempts to prevent door from opened without permission. This problem arises from the fact that door using key is easy to break. Sometimes, the user forgot to lock the door because of carelessness. Therefore, there must be an efficient system to help the user especially student to lock the door. Even they were forgotten to lock the door, that system will assist them by auto lock the door.Most doors are designed with key lock. Unfortunately, key is easy to duplicate, lost, user forgot to bring the key and lock easy to break. The locker security system proposes a proper system that is user easy to access. Using keypad, the user can enter and reset the password.  This system also can adapt to home and office door.
