Vehicle Theft Intimation to the Owner on his Cell Phone by GSM with User Programmable Number Features using PIC Microcontroller
PROJECT DESCRIPTION

The main scope of this project is to develop a wireless technology based vehicle theft information system to provide security to vehicles from theft.

Nowadays, vehicle thefts are on the rise, and therefore, demand urgent security measures to ensure proper security to vehicles and other transportation systems. If this proposed system is installed in the vehicle that someone tries to steal, then this system prompts and sends information to the owner of the vehicle through SMS using GSM technology. An added advantage of this system is that the owner can send back another SMS which can disable the ignition of the vehicle.

This project uses a PIC16F series microcontroller and a rectified power supply.  A GSM modem is interfaced to the microcontroller with the help of a MAX-232 device for communication with the vehicle. A relay is controlled by a relay-driver IC, which is connected to the microcontroller. In this system, a lamp is connected to the relay contracts to mains supply instead of an engine – for indication purposes.

If a person tries to steal a vehicle in which this system is installed, then the system circuitry generates an interrupt, which is sent to a preprogrammed microcontroller. The microcontroller sends the stolen information to the owner by SMS through a GSM modem. When the owner sends back the SMS to the GSM modem with the message reading as ‘stop the engine’, the system stops the vehicle by disabling the ignition. The microcontroller gives control instructions to the relay driver to trip the relay that disconnects the lamp.

This project in future can be enhanced by integrating a GPS system, which will give exact position of the vehicle in terms of its latitude and longitude values.

Q & A
Q:  How is an actual engine depicted in this project?
A:  A lamp is used to demonstrate the mechanism of switching off automobile engine.
Q:  How can one stop the engine remotely?
A:  By sending an SMS with text “Stop”, one can stop the engine remotely.
Q:  How theft intimation is conveyed to the owner?
A:  By pressing interrupt button, the microcontroller conveys a theft intimation message to the owner number fed in it.
Q:  How can I feed the mobile number?
A:  Any mobile number can be fed by giving a missed call to the GSM number.
