Thesis Overview

<p> </p><p>INTRODUCTION<br>1.1 Background of study<br>Has technology transformed humankind into omniscient being? Years back,<br>communication was done through difficult means like travelling to the<br>destination of the second party, posting letters est. Today people can<br>communicate easily through various means like e-mailing, face booking,<br>GSM etc. The new age of technology has redefined communication, most<br>people nowadays have access to mobile phones and thus the world indeed<br>has become a global village. At any given moment, any particular individual<br>can be contacted with the mobile phone. But application of mobile phones<br>cannot be restricted to sending SMS or starting conversation. New<br>innovation and ideas can be generated from it that can further enhance its<br>capabilities. Technologies such as infra-red, Bluetooth etc which has<br>developed in recent years goes to show the very fact that improvement are<br>infact possible and those improvement have eased our life and the way we<br>live. Remote management of several home and offices appliances is a subject<br>of growing interest and in recent years we have seen many systems<br>providing such controls.<br>2<br>These days, apart from supporting voice calls, a mobile phone can be used to<br>send text message as well as multimedia message (that may contain pictures,<br>graphics, animation, etc). Sending written text messages is very popular<br>among mobile phone users. Instant messaging as it is known, allows an<br>individual to share ideas, opinions and other relevant information. I have<br>used this to design a system that allows a platform to receive calls which<br>infact are commands sent to control different appliances and device<br>connected to the platform. The design of this control system system is based<br>on the GSM technology that effectively allows control from a remote area to<br>the desired location. The application of the suggested system is immense in<br>the ever changing technological world. It allows a greater degree of freedom<br>to an individual whether it is controlling the household appliances or office<br>equipments. The need to be physically presenting order to control appliances<br>of a certain location eliminated with the use of this system.<br>The research is borne out of the need for man to control electrical devices<br>that are remotely located to him. Anything from home devices such as<br>alarms, heaters, air conditioner and so on, IT equipment such as routers and<br>servers can be controlled.<br>The desire for man to control an object that is remotely located to him has<br>been for many ages. However, the technology that meets the perfect desire in<br>3<br>this respect has not been obtained, though there is increasing improvement in<br>technology that struggles to meet this need in terms of accuracy, speed, ease<br>of operation and limitless operation point. The introduction of the global<br>system for mobile communication (GSM) and particularly the use of handheld<br>mobile phones brought the innovation of distance communication at<br>remote location. Based on this, research utilizes this facility for remote<br>control of systems and appliances, take for instance, a man on a journey<br>inside his car suddenly remembers that he left the air conditioner (AC) ON<br>when it was supposed to be OFF. The normal condition is to drive back and<br>switch OFF. But with the GSM mobile phone in the hand, one looks on how<br>the same could be used to effect control at any point and time.<br>1.2 Statement of problem<br>Technology has advanced so much in the last decade or two that it has made<br>life more efficient and comfortable. The comfort of being able to take<br>control of devices from one particular location has become imperative (i.e.<br>important) as it saves a lot of time and effort. Therefore there arises a need to<br>do so in a systematic manner which will be implemented in the proposed<br>system. The system is an extended approach to automating a control system.<br>With the advancement and breakthrough in technology over the years, the<br>lives of people have become busier than before. With the adoption of this<br>system, we can gain control over certain things that require constant<br>4<br>attention. The application of this system comes in handy when people who<br>forget to do simple things such as turn ON or OFF devices at their homes or<br>at their offices. They can now d so without their presence by the<br>transmission of a simple call from their mobile phone. This development , I<br>believe will ultimately save a lot of time especially when people do not have<br>to come back for simple things such as to turn ON or OFF at their homes or<br>at their office once they set out for their respective work or appointment.<br>1.3 Project Aims and objectives<br>The project “GSM control system” as the title suggests is aimed to construct<br>a control system that enables the complete control of the interface on which<br>it is based.<br>General objectives of the project are :<br>a. To co-ordinate appliances and other devices through calls.<br>b. To effectively receive and transmit data via calls.<br>c. To eliminate the need of being physically present in any location for<br>tasks involving the operation of appliances with household/office.<br>d. Minimize power and time wastage.<br>e. It allows a great degree of freedom to an individual.<br>5<br>1.4 Justification of study<br>o The proposed project can be used as a reference or as a base of realizing a<br>scheme to be implemented in other project of greater level such as device<br>synchronization, temperature updates, weather forecasting etc.<br>o The project itself can be modified to achieve a complete home automation<br>system which will then create a platform for the user to interface between<br>himself and the household.<br>o It can be used by companies for management purpose example is switching<br>ON/OFF the server in other to manage the bandwidth.<br>1.5Scope of the study<br>The project covers the aspect of just being able to switch ON/OFF any electrical<br>appliance connected to the circuit.<br>1.6 Project Report Organization<br>The project is designed to have five chapters, which will explain in details<br>the various aspects of system. The first chapter gives an introduction to GSM<br>control system along with the project aims and objectives, with emphasis to<br>the scope in order to achieve the desired goal and limitations to the study.<br>Chapter two is on literature review which contains a review of previously<br>implemented systems.<br>Chapter three contains the details of the entire major component that were<br>used in the actualization of the hardware part of the project.<br>6<br>Chapter four deals with the implementation and the testing, the chapter<br>contains the major work of the project.<br>Chapter five summarizes and concludes the project work on GSM – Based<br>Remote switching system. Recommendations are also stated.</p><div><div></div></div><br> <br><p></p>
