Understanding about an Anti Theft Security system for Cars

In present days crime rate is increasing day by day and car thefts are on the rise. The vehicle thefts involving mostly cars, which accounts nearly about a million cars, were reported in the United States of America alone in 2009. Stealing a car has become very simple for the criminals as owners do not bother to take necessary precautions. The CCSN public safety department has implemented a prevention campaign to conflict the rising  number of anti-theft- alarm systems and auto burglaries.

So, the need of the hour is a better anti-theft-control-system the one that can be implemented by using several technologies like GPS system, GSM, GPRS systems. This article provides some of the microcontroller based projects involving the anti-theft-system for cars, which are proposed to protect the cars from being stolen even if they are parked in the parking area.

In present days most of the cars are designed with inbuilt anti-theft- security-systems. If your vehicle doesn’t have a security device, several security devices are available in the market, which provides the protection against thefts. This article mentions the 10 most amazing anti- theft- security- systems for Cars. These include:  OnStar, LoJack, BMW Assist and Security Plus, Car Shield, Commando FM870, Viper 1002, Cobra 8510, Cobra Track5, VINshield, and Nissan Vision 2015.

For understanding the concept of an anti-theft-security system in cars, the projects that are based on GPS and GSM security systems are given below.

3 Types Of Anti Theft Systems For Cars

1. GSM Technology Based Vehicle Theft Intimation to the Owner On Cell Phone

The main goal of this project is to use GSM technology to intimate the owner of the vehicle about any unauthorized entry. This process is done by sending an SMS to the owner, and the advantage of this project is that the owner can send back the SMS with the necessary instructions to stop the vehicle instantly.

Hardware Requirements

PIC16F8 Microcontroller, Level Shifter IC, GSM Modem, Crystal, Switch, LED, Resistors, Capacitors, Voltage Regulator, Relay Driver, DB9 Connector, Lamp, Relays.

Software Requirements

Embedded c or Assembly, MP Lab and CCS C Compiler

Project Description

Day by day crime rate is increasing, so, a better security system is very essential for vehicles. In this proposed system if someone tries to steal a car or any vehicle, the microcontroller gets an interrupt through a switch which is connected to the system; then, the system orders the GSM modem to send an SMS. The vehicle owner receives the SMS from the GSM modem informing the owner about the theft. Immediately, the owner of the vehicle can send back an SMS to the GSM modem to stop the engine.

The GSM modem interfaced to the microcontroller, receives the message that disables the ignition of the vehicle resulting in stopping the vehicle. This project uses a lamp (for indication purpose) to indicate the on/off condition of the engine.

Thus, the owner of the vehicle can protect his car from being stolen from anywhere. Furthermore, this project can be enhanced by integrating a GPS system, which gives the exact location of the vehicle in terms of its longitude and latitude. Apart from protecting the vehicle, the location information can also be sent to the owner through an SMS.

2. Vehicle tracking by GPS – GSM

The main intention of this project is to reduce vehicle thefts by finding the exact location by using a GPS modem.

Hardware Requirements

Microcontroller AT89C52, MAX 232, GSM Module, Resistors, Capacitors, Voltage Regulator, GPS Modem, DB9 Connector and LCD Display.

Software Requirements

Keil Compiler, Embedded C

Project Description

Nowadays, vehicles have been increasing day by day in our country, and along with them anti-theft- security systems for cars or vehicles have also been increasing. To overcome this problem, the following project: Vehicle tracking by GPS – GSM is useful.

This proposed system mainly includes a power-supply block, a microcontroller, a GPS, a GSM modem, Max232, and several other components. The GPS system navigates the location of the vehicle in terms of its longitude and latitude positions. The microcontroller gets the information from the GPS modem through MAX232. The MAX232 is a serial communication interface between the microcontroller and GSM modem; it converts from TTL level to RS232 level.

The GSM moderm sends the SMS to a predefined mobile which stores the data in it. An LCD display displays the location information in terms of latitude and longitude values. The microcontroller is pre programmed with the Keil software and therefore, continuously checks the GPS modem.

3. Microcontroller Based Anti-theft Security System Using GSM Networks with Text Message as Feedback

The main intention of this project is to  protect a vehicle from being stolen by using GSM and GPS. In this project, we present an anti-theft-control system for  automobiles. In present days, vehicle theft is increasing rapidly and people have started using anti-theft-control systems in different automobiles’ systems. These anti-theft-control systems are very expensive, but this project is designed cost-effectively by using a microcontroller along with the GPS and GSM.

Hardware Requirements

Microcontroller, Power Supply, GSM Module, Keypad, LCD,Proximity Sensors,Engine and Ignition Key

Software Requirements

Embedded C,Keil IDE,ISP or U-Flash,Express PC

Project Description

In this project, we present an anti-theft-control system for automobiles that tries to stop a vehicle from being stolen.  This proposed system makes use of an embedded chip with an inductive-proximity sensor. If a wrong key is entered into the keypad, the proximity sensor senses the key and sends the message to the owners mobile stating that the vehicle is being accessed. Subsequently the control system present in the car prompts the person entering the key to enter the correct password.

If the person accessing the vehicle fails to enter the correct password thrice, then a message will be sent to the nearest police station indicating the vehicle number, and subsequent to this, the fuel injector of the car gets deactivated. This makes the user helpless to start the car. This project is simple and robust.

Thus, by implementing these vehicle security system projects by using GPS and GSM technologies, a vehicle can be protected from thefts. In future, this security system will be improved to function as an integrated-data-security system for car communication systems. It would ensure  that all the data exchanged within the vehicle and outside the vehicle is protected.
