IntroductionWith ARM7 as the core, the new intelligent mobile
vehicle checking
system integrates a lot of hardware modules such as:-
Video capture
GPS positioning
Wireless transmission
By the hardware/software co-design, the intelligent mobile
vehiclechecking system implemented the functions of
Video capturing
Vehicle license recognition
Communication function(wireless transmission)
GPS positioning
Meet the traffic auditing departments needs about Mobile
VehicleChecking

GPS
GPS-634R
Receive data (300 characters) serially and store inanarray
format
Compare received data with GPGGA
If matched respective time, latitude and longitudevalues are
stored in corresponding array format
The received time(ASCII) value is converted to
HH:MM:SS (i.e. Hour, Minute and Second ) format and
displayed on ALCD.
If the stored latitude and longitude has 9 characters
than its displayed on ALCD else once again 300
characters are received from GPS
If received data doesnt match with GPGGA thenWRONG DATA SORRY is
displayed on ALCD

Alphanumeric LCD JHD162A is the display that we have used.
The block diagram is shown
It has a panel
with 2 rows and16 columns.
Along with 58
pixel selection
pattern.
If connection are proper we see the
display as shown here

Software Used Embedded C: Used for developing a C language code
for
the ARM7 processor which would control all the othermodules in
the system.
Keil Compiler: Used for converting the above developedembedded C
code to an executable code (.exe file) for
ARM processor.
Flash Magic : PC tool for programming ARM7 usingserial protocol
in target hardware (.hex files) .
MATLAB: Used for writing a MATLAB code for
processing the captured video image.
