This system builds a new intelligent vehicle checking system based on ARM7 embedded processing technology, processing technology of digital videos, vehicle identification technology, GSM wireless mobile telecommunication technology, GPS positioning technique, implements the checking to vehicles which break the rules or owe the charge. Here we are using car as mobile vehicle checker.
3. Introduction
With ARM7 as the corethe new
intelligent
mobile
vehicle
checking system implemented
the
functions
of
image
capturing,
intelligent
plate
distinguishing, GPS positioning
and
wireless
transmission(GSM), met the
traffic auditing department’s
needs about Mobile Vehicle
Checking.

6. ARM processor
ARM documentation set for the ARM7 family of
CPU processor cores, including
ARM7TDMI, ARM7TDMI-S, ARM7EJ-S, and
ARM720T
The ARM7 family is a range of low-power
32-bit RISC microprocessor cores
optimized for cost and power-sensitive
consumer applications. The ARM7 family
incorporates the Thumb 16-bit instruction
set - enabling 32-bit performance at 8/16-bit
system cost.
8. Operating Modes
• The ARM7TDMI processor has seven modes of operations:
–User mode(usr)
- Normal program execution mode
–Fast Interrupt mode(fiq)
- Supports a high-speed data transfer or channel process.
– Interrupt mode(irq)
- Used for general-purpose interrupt handling.
–Supervisor mode(svc)
- Protected mode for the operating system.
–Abort mode(abt)
- implements virtual memory and/or memory protection
–System mode(sys)
- A privileged user mode for the operating system. (runs OS
tasks)
–Undefined mode(und)
- supports a software emulation of hardware coprocessors
• Except user mode, all are known as privileged mode.
9. GPS
The Global Positioning System (GPS) is
a space-based satellite navigation system
that provides location and time
information in all weather
conditions, anywhere on or near the Earth
where there is an unobstructed line of sight
to four or more GPS satellites .The system
provides critical capabilities to
military, civil and commercial users
around the world.
10. LCD liquid-crystal display (LCD) is a flat panel
A
display, electronic visual display, or video display that uses
the light modulating properties of liquid crystals. Liquid
crystals do not emit light directly.
LCDs are available to display arbitrary images (as in a
general-purpose computer display) or fixed images which
can be displayed or hidden, such as preset words, digits,
and 7-segment displays as in a digital clock.
11. Buzzer
A buzzer or beeper is an audio signaling device, which
may be mechanical, electromechanical, or piezoelectric.
Typical uses of buzzers and beepers include alarm
devices, timers and confirmation of user input such as a
mouse click or keystroke.
12. Camera
A camera is an optical instrument that
records images that can be stored
directly, transmitted to another location, or
both. These images may be still
photographs or moving images such
as videos or movies.
13. GSM
GSM is a TDMA based wireless network technology developed in
Europe that is used throughout most of the world. GSM phones make
use of a SIM card to identify the user's account. Currently GSM
networks operate on the 850MHz, 900MHz, 1800MHz, and 1900MHz
frequency bands. Devices that support all four bands are called quadband, with those that support 3 or 2 bands called tri-band and dualband, respectively.
14. GSM antenna used in project
Screw on 7dBi WiFi Antenna with Removable
SMA-RP Base
- Simply unscrew your
manufacturer's antenna and screw on
- Removable base with 1.5m cable
(with SMA-RP connector)
- Reduce WiFi drop outs, increase
speed and reliability
- Full band 2.4-2.5GHz
- Compliant with 802.11n/b/g
(2.4GHz)
15. Process-1
When the system works, the camera in the front of the
car collects the data automatically and saves it in the
IMAGE buffer. For demo concern we are using Laptop
web camera.
16. Process-2
The system recognizes the vehicle license by digital video data.
Data from camera will be sent to the PC. In PC video capturing is
done by using MATLAB and image processing is also done using
MATLAB.
17. Process-3
The vehicle checking terminal communicates with the server center
by the SMS message on the GSM net.
The system can correctly send the position and time of the checking
vehicle to the server center by GPS positioning, therefore, the
terminals can be coordinated properly.
18. Process-4
We can send the vehicle number to
the server center in the specified
format. System captured images are
processed & vehicle number is
identified in that image using
MATLAB & the vehicle number &
its GPS location is sent to the server
center. In the data base if any of the
vehicle number is matched means its
GPS location will be send to the
mobile number who has send the
vehicle number.

20. This system builds a new intelligent vehicle checking
system based on ARM7 embedded processing
technology, processing technology of digital
videos, vehicle identification technology, GSM
wireless mobile telecommunication technology, GPS
positioning technique, implements the checking to
vehicles which break the rules or owe the charge.
