ABSTRACT
Radio Frequency Identification (RFID) is a wireless, contactless technology used to identify, track, process and share information about an object or from the surrounding. As radio frequency transponders are smaller in size, more power efficient and at the same time less expensive, this technology is growing and starting to expand significantly through all the industries. The idea of this project is to try and interface an RFID to 5V microcontroller PIC16F877 for the purpose of starting a car without using keys or a combination of PIN code or password. The idea is to develop a vehicle ignition system based on RFID technology that uses wireless in order to eliminate the use of keys. The system will also reduce the rate at which cars are being stolen because is difficult to drive off with a car without keys. RFID reader can also be interfaced to a serial communication using RS232 in order to achieve the same purpose of starting the car.RFID reader is capable of reading a transponder tag by bringing it in proximity to the reader and output the unique tag identification number through serial port at 9600bps. The reader outputs 12 byte including one start byte, stop byte and unique data byte [2]. The start byte and stop byte are used to identify that a correct string has been received from the reader. One status LED is provided to indicate card detection. The normal detection range is 10-15cm depending on the shape of the card [2]. Once the RFID starts transmitting, it will send a signal through its transmit pin to the receive pin of the microcontroller and since the microcontroller is programmed such that whenever it gets a message it will read the signal and send it to the ignition system drive that consists of an amplifier and a relay switch to start the engine of the car. RFID has found its use in banks at the moment and also in the locking system of doors of many industries
INTRODUCTION
Human perception is the ability to sense, understand, and feel the surrounding in which the individual is involved. Machine perception is the next step for modern technology and will be achieved with the help of RFID, which is a technology that brings science fiction to life. Radio frequency identification (RFID) is a technology used to identify and object with an RFID tag, contact less and without line of sight. The id of the object, which is a serial number in the form of radio waves, is sent wireless to a reader which is up to a few meters apart from the object.
The method used to carry out this project is the principle of wireless technology in collaboration with embedded systems. This project has a vehicle ignition system which will be used as the electronic device and also an RFID (Radio Frequency identification) module, which is the latest technology used for wireless communication to communicate with the microcontroller. The system will work like when the user wants to start the car, he has to bring the smart IC card that comes with the RFID close to the RFID module. The RFID uses radio frequency waves and has an inbuilt antenna to receive the signal from the smart IC card.
The microcontroller used in this project is programmed in such a way that when it receives any message it will read the message and start performing the desired task. RFID can be used as an Automatic identification and Data capture (AIDC) systems. These AIDC systems are used to track and monitor physical objects wirelessly without human interaction in case your vehicle has been stolen. The system perceives, thinks and does everything by itself [1]. In the twenty century machines were designed to think and the user had to input some data and the machine would process the data and give results.
In the twenty first century with the advancement of new technology RFID will input their own data and do the entire process totally automatic without human interaction. With the help of RFID people will be able to know the best way to drive home because it will detect the traffic jams in real time and it will safeguard their vehicles from thieves. These are some of the possibilities that this technology will offer in the close future.
Problem statement
There has been an increase in the number of cars being stolen in the country at the moment. This is obviously that there are no proper security measures that are in place to protect these vehicles. A number of security measures have been compromised by thieves. In light of this problem in our country this project is intended to improve the security system of cars by providing a wireless system that will be used to start the vehicles in place of the traditional use of keys. An RFID wireless technology is to be used in order to provide the necessary protection of cars from thieves. This technology can also be used to lock the doors of cars wirelessly for total security.
Scope of study
To get an in depth of the possibilities that the RFID technology can and will offer to the society in future. To be able to interface the RFID with the microcontroller wirelessly in order to achieve the required task since an RFID can be used for many other uses.
Methodology
The microcontroller and the RFID reader will be powered by a smooth 5V regulated power supply using 7805 regulator. The RFID module is interfaced to the PIC16F877 through the receive and transmit pins of both the devices. A 16x2 LCD will be interfaced to the PIC for display purpose. A system drive amplifier will be used to drive ignition system. The RFID reader will generate radio frequency waves through the use of a transponder tag. The tag is brought in proximity to the reader and will output a signal wirelessly and this signal is sent to the transmit pin of the reader and is communicated to the microcontroller through the receive pin. The microcontroller will then read the signal and process it and send it the amplifier drive system. The drive amplifier consists of BC547 NPN transistor and a 12V DC relay switch. The output of the drive system is then connected to the ignition system of the vehicle so that the car can start. This is incorporating wireless using RFID technology for the vehicle ignition system through interface to the microcontroller
