Thesis Abstract

Abstract
This research project focuses on the design and implementation of a microcontroller-based multipurpose security device with direction capability for securing a military cantonment. The device is specifically designed to address intruder location and detection within the cantonment premises, as well as control access to a strong room in the cantonment. The primary objective of this project is to enhance the overall security measures in a military setting by utilizing advanced technology integrated into a compact and versatile device. The proposed security device incorporates a microcontroller as its core processing unit, which enables the integration of various sensors and communication modules for effective surveillance and access control. The device is equipped with motion sensors, infrared sensors, and proximity sensors to detect any unauthorized movement or intrusion within the cantonment area. Additionally, the direction capability of the device allows for accurate localization of the intruder's position, enabling prompt response from security personnel. Furthermore, the security device features a secure access control system specifically designed for the strong room in the cantonment. Authorized personnel are granted access through biometric authentication or RFID card verification, ensuring that only approved individuals can enter the designated area. The device also includes an alarm system that triggers in the event of a security breach, alerting security personnel and deterring potential intruders. The implementation of this multipurpose security device offers a comprehensive solution for enhancing the security infrastructure of a military cantonment. By leveraging the capabilities of a microcontroller and advanced sensors, the device provides real-time monitoring and surveillance capabilities, enabling swift and efficient responses to security threats. The integration of access control features further strengthens the overall security measures, ensuring that sensitive areas within the cantonment are safeguarded against unauthorized access. In conclusion, the design and implementation of a microcontroller-based multipurpose security device with direction capability represent a significant advancement in military security technology. By combining innovative sensor technologies, robust communication modules, and secure access control systems, this device offers a holistic approach to enhancing security measures within a military cantonment. The successful deployment of this security device is expected to contribute to improved security protocols, enhanced situational awareness, and greater protection of critical assets within the cantonment premises.

Thesis 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.
