Project Abstract

Abstract
This research project aims to design and implement a microcontroller-based multipurpose security device with direction capability to secure a military cantonment from intruder location and detection, as well as to control access to a strong room within the cantonment. The device will utilize advanced sensors and actuators to provide real-time monitoring and security measures. The primary focus will be on creating a robust security system that can accurately detect intruders and provide directional information to security personnel for swift responses. The proposed security device will be integrated with a microcontroller to process sensor data and control the various security features. Infrared motion sensors will be used for intruder detection, while RFID technology will be implemented for access control to the strong room. The direction capability will be achieved through the use of ultrasonic sensors and motorized actuators, allowing the device to track and locate the position of intruders within the cantonment. The system will be designed to be user-friendly, with a graphical user interface for easy monitoring and control. Security personnel will be able to view real-time data and receive alerts in case of any security breaches. The device will also have the capability to generate reports and logs for future analysis and reference. In addition to the security features, the device will also be equipped with backup power sources to ensure continuous operation even during power outages. This will help maintain the security of the cantonment at all times, without any interruptions. Overall, the proposed microcontroller-based security device with direction capability will provide a comprehensive security solution for military cantonments, ensuring the safety of personnel and assets. By combining intruder detection, access control, and direction tracking features, the device will enhance the overall security measures in place and enable quick and effective responses to any security threats.

Project Overview

INTRODUCTION

1.1.         Background of the Study

The industrial Electronics has changed the whole field of Engineering and technology is occurring so rapidly, even in developing countries. It is so because newer technologies overcome older ones. After the industrial revolution the world shifted towards the information age with the development of computers during the1950’s.

As such, mechantronics means the principle that combines the application of mechanical and electrical means has taken over the greater part of industrial electronics which is indispensable in modern technology.

In Nigeria, security which is one of the basic lookouts in any productive firm, has been on the decrease. Most industries have gone bankrupt because of their inability to meet up to the security standard required in a modern day setting. Equally, some homes and offices have lost important documents and properties due to easy access that criminals have. There is thus an urgent need for significant security measures to improve the standard of living of the people, enhance development and put to a stop the menace of insecurity. That is the reason as a student of Computer System Engineering the project named “Intruder Detector Alarm System with direction”, was embarked on.

1.2       General Description of the Project

This electronic system consists of four sensors made up of opto couplers realized with combination of Laser beam, from Laser diode coupled into a cadmium sulfide photocell (C.D.S photocell).

This component serves as an electronic eye, the output of opto couplers conditioned by a Schmitt trigger NAND gate control Logic (74 Ls 132) TTL chip. The output of the 132 chips is used to trigger one short delay which reset an astable multi-vibrator which generates the frequency that is used to drive the buzzer alarm. Each of the sensor output is fed to a BCD to decimal priority encoder whose output is decoded to a format that can be displayed using a seven-segment display (common anode).   The buzzer is interfaced through a single transistor static switch.

The entire system is designed in such a manner that whenever somebody wants to gain entrance through the back door, the electronic eyes (optocoupler) installed at the locations respectively senses the presence and triggers a buzzer alarm at the security department of the cantonment and seven-segment display shows the exact location of the intruder.

1.3     Aim and Objectives of the Project

1.       The major aim of this project is to design and implement a microcontroller based multipurpose security device with direction capable of securing a military cantonment from intruder location and detection and to control access to a strong room in the cantonment.

2.       Another objective of this project is to ground the graduating student in electronic system design and implementation involving Random logic.

3.       This project is also aimed at acquainting the young engineers with skills for engineering, technical and scientific writing which is very indispensable in their professional practice.

4.       Another aim of this project is to familiarize these graduating students with electronic system designs that have real life application in industrial security.
