Nowadays,automobile thefts and the vehicle productionare increasing in yearly world. Thefting the vehicle is a common problem. The owners of thevehicle have take care of thefting the vehicle. The motivation of this paper isto avoid the thefting of vehicle and deduction of vehicles. When the vehiclesare theft the GSM will send messages.The owner will receive the message of their own vehicle.The owner is nowresponsible for sending the message back in effect off thefting the vehicle.
For this reasonwhen any person is stealing the vehicle the modem in the GSM will send amessage through the microcontroller which will interrupt the vehicle.On seeing themessage the microcontroller will stop the vehicle. Keywords: GSM modem, voltage regulation, micro controller.1. IntroductionAseveryone in this world prefers to makethe things easy perfect to handle, this project sets an example to some extent.In this paper we deal with the security of the vehicle. Whenever the GSM modemreceives the message from the particular mobile then the car engine getsstopped. The message received from the mobile number send to the vehiclesowners mobile number.
. Applications such as the air-conditioner, VCD player,DVD player, printer, fax machine, mobile phone etc. are examples of embeddedsystems. Each of these appliances will have a processor and special hardware tomeet the specific requirement of the application along with the embeddedsoftware that is executed by the processor for meeting that specificrequirement. The embedded software is also called “firm ware”. Thedesktop/laptop computer is a general purpose computer.2.
Proposed MethodPeoplesare using the manufacturer security alarm only. The thief had an experienceregarding this security alarm, which means their 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 todouble protect the security of the vehicle. Antitheft security system utilizes an embedded system design with Dual Tone Multi Frequency (DTMF) and a GSM to monitor and safeguard a vehicle. It secures the vehicleagainst theft. Upon activation, it automatically demobilizes the vehicle bydisconnecting the ignition key supply . This makes impossiblefor anybody for starting the vehicle in a moving time.
In an attempt of theft through the vehicle doors or boot, the system sends text message to the vehicle owner and at the same time starts upan alarm. This design popped out due to the increasing rate at which packed vehicles are stolen especially in our country, but with this design this packedvehicle is being monitor red irrespective of where it is packed, provided there is GSM network coverage. Now GSM will not send message tothe vehicle and we only we can hear thealarm from the security .
Then it is guaranteed that the vehicle will send text message to his phone, and atthe same time, have people around alerted of what is happening. Nowadays,automobile thefts are increasing and also the production of vehicle. The theft detection system of a vehicle using GSM is as shown in the Fig.
1 and 2. Figure-1 Figure.2 Block Diagram for Vehicle Theft Control System Cellularsystems using a digital technology will becomethe universal method of tele-communications.Short message service is a technique ofdelivery of small messages over the mobile networks. It is a store and forwardway of transmitting messages to and from mobiles. The message (text only) fromthe sending mobile is stored in a central short message center (SMS) which thenforwards it to the destination mobile. This means that in the case that therecipient is not available, the short message is stored and can be sent later.
Sincesignaling message system used signaling to desired channel as opposed to dedicatedchannels, these messages can be sent/received simultaneously with the voice/data/fax through GSM network. SMS supports nationaland international roaming. This means that you can send short messages to anyother GSM mobile user around the world. With the PCS networks based on all thethree technologies, GSM, CDMA and TDMA supporting SMS, SMS is more or less auniversal mobile data service.2.1 Working ofvehicle theft DETECTION BY GSMThe theft detection of the vehicle using GSM involve Vibration Sensor,Ignition Lock,Microcntroller,LCD display,GSM Modem & Buzzer.
The embeddedsystem installed in the engine of the vehicle along with theGSM modem. By entering a correct password the instrument allows to activate the12v relay and then ignition of the engine will start. Hence starts the vehicle. If anyonetries to access the vehiclespassword or theft the vehicle , then the MCU will block the entry of further password. Then the buzzer will turned on to create a noise to panic the culprit, followed by sending a message “Alert: Car Is UnderThreat” through GSM modem to the owner’s mobile for further action for prevention of his vehicle. According to the prototypemodel after entering correct password the Fan will move and at the same time, according to the instruction itwill run forward for 10 sec and backward for10 sec likean automobile. Password can be c hanged by the following proper procedure.
First enter # , then enter the old password , then new password. Now test, whether the new password is working or not. As per algorithm given below the new password will retain even after power failure.So it will work as usual. The source code is written in the embedded C language. To develop thesource code the flow chart of the project is shown in the figure below 3.
Figure-3: Flow chart for vehicle theftcontrol system by using GSM3. RESULTS AND DISCUSSIONS This GSM based vehicle theft control system retrieves vehicle status is whether it is in theft mode. This data is fed to the microcontroller, which is interfaced to a GSM modem. The microcontroller generates the vibrations and sends an SMS tothe concerned authority over GSM modem on periodical interv alls which is set by the user.An LCD display is connected to themicrocontroller for crossing the data received before beingsent over GSM. This project will be very useful to people tokeep track of their vehicles. Further,this project can be developed by making an arrangementto stop the ignition of the vehicle by the owner remotely by sending an SMS in theftsituations. The kitconsists of an ARMController, Relay circuit, GSM Module and LCD Display are interfaced on a single board and embedded on single board which is embedded to a vehicle as a control unit.
The relay is connected to theVehicle Engine Unit of the Automobile When “OFF” message sent by theowner of the vehicle to the mobile embedded in the control unit, the controller displaysthe message in theLCD as shown in the Fig.4.and invokes the relay that is connected to engine of the vehicle stop theflow of fuel by making the engine to be locked. Fig.4:Engine OFF Message Similarly when “ON” the owner of the vehicle will send a message to the mobile embedded in the control unit, the controller displays the message in the LCD is shown in the Fig.
5 and allows the fuel flow by unlocking the vehicle engine. Fig.5 Engine ON Message4.
CONCLUSIONIn this paper wehave studied and implemented a complete working model using a Microcontroller.Using this project, one can control his vehicle’s car engine by means of anSMS. The main purpose of this paper isto prevent vehicle theft. This functionality is achieved by detecting vehiclestatus in theft mode and by sending an sms which is generated automatically.This sms is then sent to the owner of the vehicle .The owner can then sent backthe sms in order to disable the ignition of the vehicle.
Thus in this waycrimes can be reduced to a great extent as vehicles today are being stolen inlarge number. Hence, vehicles today require high security which can be achievedwith the help of this application. 5 Future scopeFurtherenhancement can be done to this paper by using a GPSsystem that helps to findout the exact position of the vehicle with the help of its latitude and longitude which then can be sent to the owner of the vehicle via SMS. This data can be then entered by the owner on Googlemap to find out theexact location of the vehicle. There are many Applications of GPS based Vehicle theftdetection system using GSM technology, few of them are listed below:GPS Car theft detection can be used in transportation vehicles of Companies, schools, colleges and industries. This work can be used in our carsand even in bikes.BIBLIOGRAPHY1 B.G.
