1.1 Introduction
1.1 Background of Study
The Microcontroller Based Password Door Lock System is a design that applies automated security system in homes, Industries, military etc. The project will feature a system that will track the presence of an intruder in restricted area and also inform the user about the position of the intruder.
This Project will be based on microcontroller and other electronic design to achieve the above stated purposes. The interfacing medium will make use of parallel port. The sensors (Light Dependent Resistor and LEDS) will receive the signal when the intruder is around wile the control program will translate the received signal from the sensors to useful information about the function of the system.
In this design we have implored the use of both hardware and software to bring about the entire project. The hardware components are solely coordinated by the AT89S52 micro controller chip while the assembly programming language is used to program the chip.
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to Design and Construct a Microcontroller Based Password Door Lock System.
1.2 Aim and Objectives of Study
The aim of the study is to Design and Construct a Microcontroller Based Password Door Lock System. In achieving this aim, the following specific objectives were laid out as follows:
- To provide a cost effective and more efficient security system in areas like homes, industries military etc.
- The application of this project will enhance effectiveness necessitating to security measures. It relevance, upgrades the conventional security system to automated system that will require little of human intervention.
- To build a platform for further sophistication of automated security system by detailing all the measures taken in realizing this system (microcomputer Based Security System).
1.3 Significance of Study
Environmental security against an intruder has become a thing of individual, national and international concern. The essence of this project is to provide a cost effective and more efficient security system in areas like homes, industries military etc. The application of this project will enhance effectiveness necessitating to security measures. It relevance, upgrades the conventional security system to automated system that will require little of human intervention. This project will also build a platform for further sophistication of automated security system by detailing all the measures taken in realizing this system.(microcomputer Based Security System). This will ensure a complete intruder proof system which will take care of future intrusion technique.
This study will be of immense benefit to other researchers who intend to know more on this study and can also be used by non-researchers to build more on their research work. This study contributes to knowledge and could serve as a guide for other study.
1.4 Scope of the Study
The study focuses on the Design and Construction of Microcontroller Based Password Door Lock System. Since security systems ranges from simple to complex systems, in trends and effectiveness. The depth of my work on this project will build a system that will be able to check the security of home and small industries. It will feature four (4) sensing circuits that could be check the intrusion of an intruder in up to four different positions or location. Single alarm system that will alert about the presence of an intruder and also, the display of an intruder position using the Visual Display Unit of the microcomputer.
1.5 Limitations of the Study
During the course of this study, many things militated against its completion, some of which are:
- Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
- Research material: availability of research material is a major setback to the scope of the study.
- Frequent power failure: This made the researcher append more money on fuel to ensure sustainable power.
- Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet).
