SYSTEM FUNCTION AND COMPOSITION
As shown in the figure 1, 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. This system has the
following features:
1) Video capture : When the system works, the camera
in the front of the car collects the data automatically and
saves it in the video buffer;
2) Vehicle license recognition:The system recognizes
the vehicle license by digital video data;
GPRS Wireless Communication
The GPRS communication device used in this system
consists of Q24PL002 GPRS module made by Wave COM
and the development-board. The GPRS module is installed
on the development-board, the RS232 port on the
development-board is connected to URAT1 on the ARM7
experiment & development board in order to implement that
the ARM7 chip has control over the GPRS communication
device. The GPRS device is controlled by the ARM7
through AT instructions. The GPRS device includes 24
operation instructions in common use, 10 talking operation
instructions, 9 message operation instructions, 7 TCP/IP
operation instructions.
Introduction of ADS integrated development environment
The ADS integrated development environment is a
microcontroller for ARM which is developed by the ARM
Company, its full name is ARM Developer Suit and the
mature vision is ADS1.2. ADS1.2 supports all the ARM
microcontroller before ARM10, supports the software debug
and JTAG simulate, supports the assembly language, C and
C++ language. It has the merits of high compile efficiency
and rich system libraries. The environment can run on
Windows98
