| Access control systems offer numerous benefits and are able to constitute extremely good solutions for securing an area of high or very high importance. An access control system allows restriction, monitoring and directing human trafficking as cars to a location or from a location. In generally at access control systems call the managers of circulated spaces or areas where must enter only authorized persons. To access the vehicles in different areas are frequently used automatic barriers. This paper presents such an access system, achieved a small scale named ˝automatic barrier model˝, that uses photovoltaic panels (PV) as main energy source. Automatic operation of barrier is provided by a development system achieved around a microcontroller. In the first part of paper is presents the structure and minimum requirements of development system. Also are highlighted aspects of dimensioning and design for both parts hardware and software respectively. To achieve electrical diagrams and PCBs was used a dedicated software. Finally was tested the achieved automatic barrier model. The tests consist of verifying the correct operation of the automated system. Were made test regarding to automation and to power supply from PV panel. Experimental results show a smooth functioning of experimental automatic barrier powered by PV panel and can be successfully expanded at real scale. |
