DESIGN AND CONSTRUCTION OF A HOME CONTROL SWITCHING SYSTEM USING GSM

CHAPTER ONE

INTRODUCTION

The expectations of the public toward technology are rising quickly today. People require an easily accessible, intelligent system that can improve their quality of life and level of safety. An electrical and electronic system called a GSM-based home automation system was created to allow mobile phone control of house appliances. GSM and PLC are the system's two primary technologies. Power line communication (PLC) and GSM (global system for mobile communication) are both acronyms. In this investigation, the GSM phone used to receive commands and transmit them to the controller is a Nokia 6100. The potential to integrate mobile technology into home automation systems is made possible by the quickly growing nature of mobile communication technology and its widespread availability.

With the aid of its driver, the "AT" instruction is passed between a phone and a microcontroller over an RS-232 serial interface.

The technology is built on the GSM network's basic idea, which allows users to use a mobile phone to remotely control the functioning of appliances. Alternatively put, it would convert a typical home into an intelligent home. The controlling circuit is the most crucial part of the interface and communication between home appliances. Peripheral interface controllers (PICs) connected to mobile phones were used to accomplish it. By just touching the mobile phone's keypad, the user can turn appliances ON or OFF.

To turn on or off any home appliances, including a lamp, air conditioner, fan, and others, the user sends GSM data in the form of an SMS (short messaging service) message. The user may also be given access to the appliances' ON/OFF state at any time. The system can be made better so that it informs the user of each appliance's status.

1. PROBLEM STATEMENT

Many electrical and electronic gadgets are used in most households, including television sets, ceiling fans, air conditioners, light bulbs, video players, radios, etc. In the conventional manner, all of these equipment must be switched on and off. When frequent switching operations are necessary, this manual way of switching any home appliance is an inconvenience for physically challenged, elderly, or even young and active people. As a result, an easier switching technique is created using the advanced switching mechanism for electronic household appliances known as GSM. This entails turning on and off household appliances via GSM.

1.2 AIM/ OBJECTIVE OF THE PROJECT

AIM: The purpose of this research project is to design and build a GSM network-based home appliance control system.

OBJECTIVES:

The following are the project's goals:

1. To design a home switching system based on IOT.

2. To ascertain the GSM switching's bandwidth or spectrum.

3. To understand the GSM function switching architecture.

4. To authenticate the home-based cell phone interface (control unit), which would transfer the instructions to a microcontroller to carry out the necessary action or function.

1.3 SCOPE OF THE PROJECT

The following are the project's work scopes:

1. By communicating with the GSM module on a mobile phone with a SIM card, users can remotely control the functions of appliances.

2. The GSM module enables SMS to be sent and received to and from a mobile phone.

3. The PIC microcontroller and GSM module will be connected by a standard serial communication wire called RS-232.

4. A PIC microcontroller will be interfaced to the appliance-connected control circuit. The software elements used to monitor and operate the appliances are contained in it.

5. The relay and control circuit that is used to monitor and manage the state of the home appliances.

OPERATION OF THE SYSTEM

The system functions as a remote sensor for electrical appliances in a home or business to determine if they are ON or OFF. At the same time, the user can manage the electrical appliances in their home by sending an SMS message to the system, for example, turning on the air conditioning before coming home. The chip acts in accordance with the received signal by sending an SMS message to the user's mobile phone in the event of a fire or security situation. It also functions as automatic and immediate reporting to the user in the event of an emergency for home security, as well as immediate and automatic reporting to the fire brigade and police station according to activated sensor to decrease the time required for tracking action.

A sketch of overall design of the home appliances control using GSM is shown in the figure below.

ARCHTECTURE OF THE SYSTEM

It is adaptable to all security system levels. The three primary parts of the system's architecture are the GSM module, the interface circuit, and the many sensors that are used. The GSM module's purpose is to enable remote communication using the RS-232 serial communication protocol between the user and the controller. The controller's role is to continuously monitor the outputs from various sensors and send messages via the GSM network in the event of an emergency. As such, it serves as a 24-hour monitoring system and is constantly looking for messages sent by users via the GSM module, such as instructions to turn on the air conditioning, for example.

1.4 JUSTIFICATION

The mobile phone and the control unit are two different components of the control system. There will be two operating environments as a result. The control device will only function indoors, within the permitted temperature and humidity ranges for the hardware, whereas the mobile phone will function both indoors and outdoors.

1.5 LIMITATIONS OF THE PROJECT

The project has the following limitations:

• The receiver needs to be situated in a place where a cellular phone network can send out a strong enough signal.

• Only those who will be successfully verified will be able to communicate with the control module.

• The only things that could be controlled are things that have ports for electrical control.

• Communication with the receiver is made possible through the I/O ports of the controlled devices.

• The receiver must always be connected to a power source (120 volts or 220 volts).

• Only a cell phone with SMS message capability can be used to operate the controlling device.

• SMS messages must be received by the controlling unit and decoded.
