Introduction

This system mainly focuses on the tracing of the robbed vehicle

and thus provides security to the user.

This system uses RFID based technology to revolutionize the

standards of living and provide a cost efficient system.

The system is wireless and therefore more adaptable and cost-

effective.

The system uses GSM technology thus providing ubiquitous

access to the system for security and allow the authority to

withhold the law breaker.

Problem statement By using RFID tagging make a system to trace robbed vehicles,

detect over speeding vehicle on bridges and maintain a database of

vehicles so that the vehicles info can be wirelessly obtained.

Case1: When the users vehicle is lost he/she reports to the

RTO about the lost vehicle. The user provides the cops with the

RFID tag number which is then fed to the system at the check

post. So as soon as the robbed vehicle comes within the range

of the RFID reader alarm is raised and gates are closed

automatically at the check post also, the RTO and owner is

informed about the tracing of vehicle at that check post.

Case2: When a vehicle cross the speed limits over the bridge in

absence of RTO personnels the system is used to track the

vehicle which is over speeding. The vehicle is reported to the

RTO by sending a SMS mentioning the vehicles tag ID.

Operation:

1st application

RFID reader has been interfaced with the PIC microcontroller

(16F877A) and the RFID tag number of the robbed vehicle has

been fed into the the microcontroller using a keypad.

The microcontroller (16F877A) is programmed to send a

signal to the gate motor when the fed tag number has been

traced.

2nd application

2 RFID readers have been interfaced at the 2 PIC

microcontrollers (16F877A) and installed at the start and at

the end of the bridge respectively.

When vehicle A passes the reader at the start of bridge one

interrupt is sent to PIC microcontroller (18F452). In this PIC

controller the reference time limit for crossing the bridge is fed

using a program. So when this controller receives an interrupt

it starts the timer for that particular interrupt.

When the vehicle reaches the end of the bridge another

interrupt is sent by the 2nd PIC microcontroller (16F877A) and

the multitasking PIC controller stops the timer and checks the

time duration. If the vehicle is within the reference time limit

that is it is within the speed limit and if it is not then it sends a

signal to the 1st PIC controller.

The 1st PIC controller then sends a message via GSM module to

the RTO office.

Flow chart:

Application 1:

Enter the tag ID

tag ID stored in controller memory

Check for a interrupt by

reader

If 12 bit ID same as stored

No

Actuate the gate motors & ON the buzzer

Send AT cmds to GSM modem to

send SMS to RTO or owner

On every int 12 bit ID from reader

will be stored on controller

Yes

Yes

Application 2:

Scan & Detect a vehicle with its tag ID

Start a timer & increment till the

second reader reads the vehicle ID.

For two vehicles make P.1 or P.2 high

indicating the start of timer for a vehicle.

Stop the counter & make P.3 and P.4 high indicating the reading

by second reader

Check if the timer count is less comparing

with the pre-set

Send a notification via GSM telling about the

vehicle crossing the speed limit.
