Project Implementation:
Conclusion:
• Equipped with an Intel Celeron 1 GHz CPU and 2.5" HDD, UNO-2170 is a powerful industrial-grade computer that can
handle large amounts of data. UNO-2170 has passed a 1 G random vibration test with a HDD inside, so the system could
use Windows 2000 for the OCR software to run on
• UNO-2170 is equipped with a PCMCIA slot and PC/104 extension kit that can be used for wireless data dispatches and
camera capture cards. So all license plates can be captured and dispatched through a wireless network to the command
center for identification
• By adding an ADAM-4055 module, a solid power management system could also be created to perform safe shutdowns
• USB and COM ports on UNO-2170 make expansions and future device connections easier

Project Introduction:
Because of its reliable design and excellent vibration resistance, UNO-2170 was chosen for a mobile
License Plate Recognition (LPR) system in Taiwan. Police cars were equipped with the License Plate
Recognition system to process observed license plate numbers through a central database of stolen cars
at the headquarters.
The system makes use of ADAM-4055 for power management, and is equipped with a Global Positioning
System (GPS) module, add-on video input, real-time Optical Character Recognition (OCR) software and
wireless connectivity via GPRS/CDMA/WLAN.
System Requirements:
• A rugged and compact platform to endure wide temperature ranges
• Anti-vibration and anti-shock design for reliable performance in a vibrating and moving environment
• Power management for safe shutdown of system
• Video input capacity for license plate number capture through PC/104 interface
• Efficient OS for quick start and stop of system and compatibility with OCR software
• GPS/GPRS/CDMA wireless connectivity for mobile usage
System Description:
When the police car starts/stops the engine, ADAM-4055 ensures that the system is activated/deactivated.
A camera is mounted in the front of the car, controlled by the driver. With a video capture card in its PC/104
extension slot, UNO-2170 can receive image data from the camera. This image data is then processed
by the OCR software to filter a license plate number out from the captured image. The number is passed
to the central database at the headquarters by GPRS/GPS or WLAN, where it is used for a query into a
database for stolen cars. The query returns detailed information to the police car and displays it on an
LCD monitor for the police officer.
