ABSTRACT

The rate of car theft nowadays according to daily crime analysis is on the increase. Manual key locks have proven to be inefficient. This thesis aims at designing a radio-controlled car door locking system. The two main objectives are to unlock a set of vehicle doors when the owner approaches his or her vehicle and to lock the vehicle after the owner leaves. In addition to automatic door locking the system monitors the engine for inactivity. After five minutes of inactivity of the driver, the engine automatically deactivates. In order to design this system, the establishment of wireless communication between the vehicle owner and their vehicle is required. The radio transmission must ensure vehicle security and also be reliable in various climates. In this study, I am using radio frequency identification mechanism for the automation. RFID, Radio Frequency Identification is an inexpensive technology, can be implemented for several applications such as security, asset tracking, people tracking, inventory detection, access control applications. The door locking system is implemented using passive type of RFID which can activate, authenticate, and validate the user and unlock the door in real time for secure access. The advantage of using passive RFID is that it functions without a battery and passive tags are lighter and are less expensive than the active tags. A centralized system manages the controlling, transaction and operation task. The door locking system functions in real time as the door open quickly when user comes near the vehicle. The system also creates a log containing check-in and check-out of each user along with basic information of user.

CHAPTER ONE

INTRODUCTION

1.1     Background of the Study

The Autonomous Radio Identification Vehicle Locking System is designed to improve vehicle security and accessibility. With the use of wireless technology vehicle owners are able to enter as well as protect their automobiles with more passive involvement. Originally, vehicles were accessed and secured manually by inserting a key into a lock. More recently, a keyless entry system was created which allowed the owner to lock and unlock their vehicle with the touch of a button. Communication between the owner and the vehicle was established using wireless technology. With the Autonomous Radio Identification Vehicle Locking System, wireless communication expands upon past technology. It is able to grant access and security without pushing a button. For this new technology to work, the vehicle's internal computer must be utilized in conjunction with sensors that can detect the owner's presence, as well as the status of the locks. Finally, the circuit design needs to turn the locking mechanism in the lock or unlock position. The fields used are RF communication, digital systems software programming, logic circuit design, as well as microelectronic design [1Dr. S .N. Sing/ 2018].

RFID, Radio Frequency Identification is a fundamental and inexpensive technology that enables wireless data transmission [Zeydin Pala ET all, 2007]. This technology has not been very often used in industry due to lack of standardization among the manufacturing companies earlier. RFID technologies are efficient [Zhang, 2005] and secure compare to other network. With RFID, wireless automatic identification takes a very specific form: the object, location, or individual is marked with a unique identifier code contained with an RFID tag, which is in some way attached to or embedded in the target. RFID is not a single product but a comprehensive system, a typical RFID system include three basic elements: RFID tag (transponder), reader (transceiver) and back-end application system (or database), which demands the support of the computer network. The software is used for management, controlling, transaction, operation and maintaining record of the various users.
