Aim of the project

• In today’s world vehicle tracking has become a big necessity

• A vehicle tracking system is an electronic device installed in a vehicle to track vehicle’s location and display system using SD-card

• The information we are stored in SD-Card for the later analyses to download the personal-computer.

• Aiming for low cost and easy operation

Existing methods

• Lojack -Uses radio frequency transmitter but not implemented in India

• LORAN-Uses radio frequency transmitter not implemented in India

• DGPS-Increases the accuracy but is quite expensive

• Most of small transport companies don’t use any vehicle tracking system at all due to its high cost and complex user interface.

Novelty in my solution Using PSoC (programmable system on chip)

which is low cost and has several configurable blocks which can be used to add more features

Sd card is interfaced With microcontroller to retrieve the data.

Basic principle

The position is taken by the GPS receiver through GPS Satellite

Sd-card and RTC interfacing with the microcontroller.

Specifications

RS232 interface between GPS Rx and PSoC using first UART

Second UART of PSoC for RS232 interface Can retrieve data at any time using sd-card Power can be derived from Vehicle battery

itself

start

Initialize UART

Interface GPS reciever with the Microcontroller

GPS modem receives the dataand send it to microcontroller

Microcontroller takes the GPS data and send it to sd card

From sd card we can send the GPS data from microcontroller to user

End

Block Explanation

SD-Card is used to store the GPS locations

GPS Receiver-used to receive the satellite navigational data and calculate the position of the vehicle

PSoC CY8C24966- used to interface the GPS receiver with GSM modem

Tools and Language Used

Tools Used-PSoC Designer software to develop the code

Hardware used-CY8C29466-24PXI microcontroller-GPS receiver-GSM Modem-Mobile phone for sending and receiving sms

Applications

Mainly used for fleet control Stolen vehicle searching Race control in sports Animal tracking (wild life study)

Advantages over other scheme

Can be used for air applications as it is using the satellites for positioning

No access fee required to access the navigational data.

Reliable vehicle tracking.

Disadvantages

Still expensive Limited by the resolution (few tens of

meters) No map based software hence for city

applications not suitable. Needs care and handling (or requires

rugged packing on top of the vehicle)
