The Present Situation:
Since the advent of automobiles right from the steam engines to the very futuristic cars of today, newer technologies merged into it to develop better and advanced systems. As a result automobiles have become costly. With the increase in the number of theft of cars, over time various security systems developed. These security systems were inbuilt in the cars and each car has an individual security system centering on the car itself. The problem with such systems is that if a vehicle is stolen and the number plates are changed it becomes quite difficult for the police to trace them. The only other visual differences that can be noted are the engine numbers and the chassis numbers. But that’s not a practical solution. In our project we aim to develop a tamper proof unique identification system for each automobile that can help in vehicle identification and at times also disabling the automobile.
In the present scenario, if a car is stolen then the owner of the car registers a
complaint at the nearest police station. Then the police will be on the lookout for a car with the same number plates. But this system will have a lot of loopholes as the number plates can be changed any time.
Our project proposal:
In our project we propose to have a Radio Frequency based technology that will be able to provide an individual numbering system to all the vehicles being manufactured. Also, all cars should have an electronic switching system that can be activated or deactivated by the use of RF transmitter and receiver.
Setup:
The RF tags will be fixed inside the car. The reader antennas will be mounted on the poles reader that will be able to detect the unique number of the vehicle. The RFID in turn will be connected to the serial port of a computer. The computer will have a Visual Basic front-end and an MS-access database that will contain the information of all the cars that have been stolen. A microcontroller circuit will also be connected to another serial port of the computer. This circuit has a radio frequency transmitter that will be able to send information to a receiver circuit
fitted on the car. The receiver circuit also has a relay switching mechanism that will be able to de-activate or activate a car based on the signal received.
