Project - Control electrical device by using radio frequency technology remote (RF).

Description - Designed to operate four electrical loads by using Radio Frequency technology remote (RF).

Aim - To assess the student ability to apply research methods in a real scenario that will produce a high quality literature review, data analysis and approach the specific technical project.

Objective - To evaluate the skill acquisition in research methodology techniques, in terms of source and critically review literature, range of data analysis methods and approaches relevant to the chosen project topic.

Description of the Technical Project idea, research problem, proposed solution and methodology

The main intention of this project is to control home appliances by using Radio Frequency technology remote (RF), which helps to turn the electrical loads such as light, and fan ON and OFF through an RF-controlled remote. This is an advanced technology for home automation as it is used to make homes very smarter without requiring any switches on the walls.

Nowadays conventional wall switches are located in different parts of a house and, therefore, to switch on such switches someone has to go there and press them to turn the loads on or off. It becomes very difficult for the elderly or physically handicapped people. Hence, this project is proposed to control home appliances through an RE. With this system, by pressing selected switch of a remote its corresponding load can be controlled.

The proposed system uses a microcontroller of the 8051 family and a rectified power supply. An RF transmitter is connected to the transmitter end with the help of an encoder device. The push buttons arc connected to the microcontroller as input switches. The commands arc sent by the push buttons to the receiver to control the electrical loads.

An RF receiver is connected to the receiver end with the help of a decoder device. The electrical loads are controlled by the TRIAC device which is connected to the microcontroller with the help of an op-isolator to isolate it from the controlling section.

The electrical loads are controlled by the RE remote wherein the commands are sent by the transmitter, and based on these commands- the receiver controls the electrical loads when corresponding switches are pressed to turn ON and OFF.

Task:

A critical study report of the project work undertaken and done during RM stage has to be presented in this coursework and shall be called the critical study report. This report should have a clear start beginning with the introduction to the project and end at the pre-design stage. Information within submissions should also be logical and well grouped. Students are advised to follow the instructions given below to present the Critical Study Report.

Critical Study Report should be structured and submitted in the order as given below:

1. 2 cover sheets - front page

2. 1st page - Details of the Project (as per template given in page 4)

3. Turnitin report

4. Project Risk Assessment form

5. Formal Project Proposal (Approved)

6. Abstract

7. Table of contents

8. List of Figures

9. List of Tables

10. List of Symbols

11. Chapter 1: Introduction

12. Chapter 2: Literature review

13. Chapter 3: Data Analysis/ Pre-Design

14. Conclusion

15. Future work to be carried out in Technical Project.

16. Gantt Chart

17. References

All the contents taken from the external sources such as internet, journals and text books must be compulsorily cited and the corresponding references should be included in the reference page. Text contents without proper citation will be considered as plagiarism and students may need to face disciplinary action as per college policy.

Students are expected to present the following contents under each heading:

Abstract

The Abstract may contain the description of the topic, need of the present study, important applications of the topic, a brief description about previous literatures, predesign, future work to be carried out in Technical Project and conclusions. The word count is limited to 250.

Chapter 1: Introduction
The introduction may contain an overall view of the topic, Identification of the need, Problem description, Objectives, Scope, Value & Importance of the research and feasibility study.
The student may provide an introduction to the research problems pertaining to the project with detailed explanation.

Chapter 2: Literature review

The students are expected to critically evaluate minimum of five previous literatures pertaining to their project topic that contain key finding of previous authors such as methodology adopted, parameters used, results obtained and important conclusions along with shortcomings / gap areas. In text citation must be made without fail. The in text citation and referencing should be in CCE Harvard referencing style. This chapter should precisely link the present study to the collected literature with gap areas identified. Finally a chapter summary may be presented. Chapter 3: Data Analysis / Pre-Design

Students may provide statistical tools planned to use in Technical Project (TP), 2-D, 3-D drawings, Proposed model/ circuit diagram, other data interpretations using graphs, surveys results, case studies, research plans, activity flow charts, Gantt charts etc. The outcome of this chapter would be useful to do the experimentation, fabrication and associated detailed analysis of the research problem during TP stage. Finally a chapter summary may be presented.

Conclusion & Future work:

The conclusion made in the report should correlate with the aims and objectives of the project. Future works planned for Technical Project stage are to be mentioned.
