Development of GSM Based Vehicle Anti-theft Security System : Literature Review

Week6

Before this, peoples are using the manufacturer security alarm only. The thief had an experience regarding this security alarm, which means they work is getting easier to steal the car because they had well known about the alarm circuit. They know when the time to cut-off the alarm and had well known about the system. So, it is important to double protect the security of the car.

Antitheft security system utilizes an embedded system design with Dual Tone Multi Frequency (DTMF) and a GSM to monitor and safeguard a car. It secures the car against theft. Upon activation, it automatically demobilizes the car by disconnecting the ignition key supply from the car battery. This now makes it impossible for anybody so starts the car, let alone moving with it. In an attempt of theft through the car doors or boot, the system sends text message to the car owner and at the same time starts up an alarm. This design popped out due to the increasing rate at which packed cars are stolen especially in our country, but with this design this packed car is being monitored irrespective of where it is packed, provided there is GSM network coverage. From the research conducted, it was found out that majority of the existing car security system uses only alarm, and doesn’t send text message to the car owner let alone of demobilizing the car. But with the use of GSM network, the owner is guaranteed that the car will send text message to his phone, and at the same time, have people around alerted of what is happening. Added to this is that the car will not be move because it has been demobilized. To make sure that the circuit are possibly run are by using the PIC16F877A microcontroller.

The main circuit are controlling the overall circuit either the GSM circuit or the supply current to overall car system. The Microcontroller PIC16F877A is chosen because of this controller I have learned in Microcontroller subject in Unikl BMI. It can work on different language either the assembly language or the C language. But mostly student will prefer C language because it would be easier to understand and can run simply that the assembly language. The program needs to compile as the HEX file to apply to the circuit.

Figure below are shown the example product that are already in the market, this product are quite similar with my project but the price are quite expensive compare to my project:
