Design And Implementation Of A Smart Device That Counts The Number Of People Inside A Conference Hall; And Prevents People From Entering Once The Room Has Reached Its Capacity.


Chapter One


1.0 Introduction

The industrial batch counter is an electronic and electrical device that handles the counting and controls the flow of individuals using an automated slide door that allows access only when the administrator permits. The technique involved in the design is a simple sensor unit that opens and closes the door when someone obstructs the light path. These parameters can be used to determine when someone has moved in or out of the conference hall (for instance). The light sensing type involves monitoring the unit with photon or optical devices; this consists of the encoder (transmission path or the source of energy) and the decoder (receiver unit that converts the light intensity to electrical signal). An LED emitter, combined with a photo detector (Light Dependent Resistor, photo transistor or infrared sensing diode) in proximity, form a very useful object called opto-coupler or opto-isolator. When the opto coupler is obstructed, the door opens and the display shows an increase or decrease of individuals in the room (depending on the path followed). This project report creates a greater picture of the industrial batch counter.


1.1 The Aim and Objectives of the Project

The aim of this project is to demonstrate a smart device that counts the number of people inside a conference hall; and prevents people from entering once the room has reached its capacity.


1.2 Justification of the Project

The need for counting the number of persons inside the conference hall is for statistical record, which will help the conference hall management take a proper account of people; and as well, control the conference hall capacity from being over populated.


1.3 The Scope of the Project

This project covers the features of the capacity monitor, the hardware description, the use of transistor-transistor logic and microcontroller, how the system works and its applications.


1.4 The Project Report Organization

This project report is organized into five chapters.

  • The first chapter covers the introduction, aim scope and justification of the project.
  • The second chapter talks about the technology behind the project, the description of the microcontroller, as well as the working principle of the project.
  • Chapter three covers the methodology of the project.
  • Chapter four discusses the designing and construction of the project, as well as other components used in designing this project.
  • Chapter four also talks about the testing of the individual components and packaging of the project.
  • And lastly, chapter five summarizes and concludes the project.

Chapter Five


Conclusion and Recommendation

This is the last chapter of the project. This chapter summarizes the entire project, and also provides suggestions that could be applied to the capacity monitor in order to make the device better.


5.1 Conclusion

Overcrowding often leads to the collapse of structures and sometimes death. This project is designed to help control the overcrowding of a hall. This can be achieved when the system stops opening the door whenever the count equals the set number (i.e. the door stops opening once the hall has reached its capacity; and can only open once people have left the hall). This kind of gadget can be modified and used in stadiums and other public circuit places such as auditoriums, cinemas, airports, as well as banks in order to reduce overcrowding.


5.2 Suggestion for Further Improvement

Although this project (if implemented) could be described as “state-of-the-art”, there are certain areas that need to be improved.

These areas include:

  1. Using a radio frequency proximity sensor to replace of the optical sensor.
  2. High precision mechanized door.
  3. Attaching metallic scanners to the doors.
  4. Hall management should always appoint people to door post in order to avoid “circumvention techniques”.

5.3 Recommendations

Technology is the strength of a nation. It has gradually become a part of everyday life; for this fact, its growth in a nation should not be neglected. Technology can be improved in Nigeria by the following ways:-

  1. The standard of projects should be raised.
  2. More practical laboratories should be built in order to expose the students.
  3. Functional libraries should be built.
  4. Government should invest in research.
  5. Exhibitions are to be conducted by schools-both private owned and government owned to make it competitive.
  6. Enough time should be mapped out for practical classes.
  7. Internet facilities should be provided for easy and faster research.
