GSM ModemGlobal system for mobiles(GSM) technology is used to establish cellular connection.

It is used for transmitting mobile voice and data services.

A wireless modem behaves like a dial-up modem.

The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves. 9

GPS ModuleGPS Wireless communication module. This design adapts the current leading GPS technology and the integrated positioning chip LEADTEK LR9548S.

A GPS framework computes its position by accurately timing the signal sent by GPS satellites high over the Earth.

GPS Receiver gets the location information from satellites8051 Microcontroller8051 chips are used in a wide variety of control systems, telecom applications, robotics as well as in the automotive industry.10

The 8051 architecture provides many functions such as central processing unit(CPU),random access memory(RAM),read-only memory(ROM),input/output(I/O),interruptlogic,timer, etc. in onepackage.

DTMF tone decoderThe dial tone which comes out from the telephone set or mobile phone is Dual Tone Multi-Frequency.

The name was given in light of the fact that the tone that we heard via telephone is really making up of two different frequency tones, subsequently the name dual tone.

11

The DTMF tone is a form of one way communication between the dialer and the telephone exchange.

A complete system comprises of the tone generator and the tone decoder.Infrared sensorsItis an electronicsensorthat measuresinfrared(IR) light radiating from objects in its field of view.

Usually this radiation isn't visible to thehuman eye because it radiates at infrared wavelengths, but it can be detected by electronic devices designed for such a purpose.

Block diagram for detecting thief movement

Thief make an attempt to unlock the car

WorkingThe advance vehicle security system consist of GSM modem, GPS module, 8051 microcontroller, infrared sensors, relay, paint spray and high voltage mesh.

The main circuit is divided into two circuits one is for detecting the motion of thief using infrared sensors and other is for DTMF tone decoding for switching on/off the relay.

When thief tries to unlock the car, the infrared sensors placed near the car door will sense the motion or movement and will sent the signal to 8051 microcontroller. 17

The microcontroller which is connected to triggering circuit will send the triggering signal to relay.

The relay is connected to GSM mobile through earphone.

The microcontroller will send triggering signal three times to GSM mobile and call will be made to user informing him or her that someone is trying to unlock the vehicle.

The second part is for controlling or switching different systems like engine ignition, fuel supply, electric shock mesh and windscreen paint spray using relay.

18Cont...

Cont...19 The relay is controlled using GSM mobile and DTMF tone decoder.

DTMF tone detection and decoding is done by IC MT8870DE.

This IC MT8870DE recognizes the dial tone from a phone line and decodes the tone pressed from the mobile keypad.

The dial tone which comes out from the telephone set or mobile phone is Dual Tone Multi-Frequency.

Cont...The DTMF tone is a form of one way communication between the dialer and the telephone exchange.

Here we are utilizing the IC MT8870DE, the principle part to decode the input dial tone to 5 digital outputs.

These output bits can be interfaced to a PC or micro-controller for further application.

For each keypad number pressed there is particular range of frequency which will be decoded by DTMF decoder circuit.

20

Cont...Depending upon the system like ignition cut-off, fuel supply cut-off, windscreen paint spray and electric shock mesh, the number of relays controlling them will be added.

Here we are using four relays. The microcontroller is programmed in such a way that each keypad number will be controlling relay which will further control these systems.

The owner will send the DTMF tone to the GSM mobile placed in the car.

The DTMF tone will be decoded using IC MT8870DE which will be controlling relays to activate security system. 21

Cont...

These separations and satellites locations are utilized to compute the location of the receiver utilizing the navigation mathematical statements. This location is then displayed using online web application through Google maps or through offline tracking using GSM.

Four or more satellites must be visible to acquire an exact result.

The recorded area information can be stored within the tracking framework.

This permits the asset's location to be shown against a map backdrop either in real time or when analysing the track later, using GPS tracking software. 26

Cont...

27 Offline tracking of vehicle using GSM. Online tracking of vehicle using web application.

Cont...In offline tracking GPS receiver after receiving the signal from satellites calculates the position of vehicle and converts it in the form of latitude, longitude and altitude and speed information.

In case of Accident GSM modem or mobile will send the help message to the family member and to others whose numbers are registered.

Through web application the client can likewise produce history report of the vehicle.

The history report of vehicle comprises of separation secured, vehicle status (ignition on/off), fuel status, velocity report, temperature report and AC on/off report.28

Cont...29

MSG System when accident occur

Generate history report of vehicle.

Cont...Working of Accident NotificationWhenever accident occurs MEMS sensor detect and sends electrical signal to the microcontroller.

By using GPS , we get particular location where accident occurs.

The GPS positioning is done in the form of latitude and longitude along with the exact location of the place with the exact location of the place by making Google maps .

Using various sensors are placed which indicates occurrence of an accident just like gas sensor, alcohol detector, accelerometer. 30

Cont...If range of that sensor increases beyond specific range then buzzer will on for one minute .

Driver cant stop the buzzer within one minute then it will detect as a accident .

Then a message will send to owner, police station & two previously stored numbers with co-ordinates of that location.
