INTRODUCTION:

With ARM7 as the core, the new intelligent mobile vehicle checking system integrated a lot of hardware modules such as image capture, GPS positioning and wireless transmission, the design of the system software used the embedded software developing platform based on ADS integrated development environment. By the hardware/software co-design, the 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.

DESCRIPTION:

The project “DESIGN OF INTELLIGENT MOBILE VEHICLE CHECKING SYSTEM BASED ON ARM7” contains 32-bit ARM microcontroller, alphanumeric LCD, PC, GSM, GPS, buzzer, Laptop web camera and power supply.

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.

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.

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.

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.

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.

ARM7TDMI-S architecture based LPC2103 microcontroller from NxP is used to implement this project. This is a 32-bit microcontroller acts as the heart of the project, which controls the whole system. It contains 8k RAM, 32k Flash, 2 Timers, 4 external interrupts, 2 UART’s, 46 GPIO’s, I2C communication, RTC, ISP programming, JTAG debugging support etc.
