AbstractLucrarea de fa i propune s ofere o modalitate de a gestiona accesul ntr-o incint i de a aduga un plus de siguran persoanelor i bunurilor din interiorul acesteia. Soluia folosit este un sistem ncorporat care interacioneaz cu lumea exterioar i reacioneaz la evenimente n timp real. Sistemul pentru gestionarea accesului utilizeaz pentru autenficare carduri magnetice n combinaie cu un cod pin format din cifre zecimale. Deoarece folosete carduri bancare, uureaz utilizatorul de a purta asupra sa multiple cartele de acces suplimentare, cum ar fi cartele magnetice de proximitate prin frecven radio. n plus, folosind carduri bancare, sistemul este mai sigur i mai greu de spart fa de sistemele actuale bazate pe infrarou. Sistemul nu se oprete niciodat din execuie (cazul ideal), iar pentru c implementeaz doar funcionalitatea de a gestiona accesul, are un consum redus de electricitate. Deoarece lucreaz n timp real are o vitez mare de execuie i ntrzieri minime. Pentru c implementarea hardware a sistemului are costuri i dimensiuni reduse, utilitatea acestuia este extins, avnd o plaj mare de utilizare; acesta poate fi montat pe orice u sau barier de acces fiind independent de numarul utilizatorilor. Sistemul se instaleaz foarte repede, iar odat instalat poate fi utilizat foarte uor avnd o interfa prietenoas.

Cuvinte cheie: acces, card magnetic, cititor de carduri, cod, control acces.

Sistem embedded pentru gestiunea accesului ntr-o incint

AbstractThis paper aims to provide a way to manage access to a site and add an extra safety of persons and their properties. The solution used is an embedded system that interacts with the outside world and react to events in real time. Access management system its using for authentication magnetic cards in combination with a PIN code composed of digits. As its using bank cards, facilitate the user to carry multiple cards, such as radio-frequency magnetic proximity. In addition, using credit cards, the system is more secure and more difficult to break compared to current systems based on infrared.

The system never stops running (ideally), and because only implements the functionality to manage access, has reduced electricity consumption. Since works in a realtime, the execution speed is fast and minimum delays. Because hardware implementation of the system size and cost is reduced, its usefulness is extended with a large range of use; it can be mounted on any door or access barrier, beeing independent of the number of users. The system installs quickly, and once installed can be used very easily with a friendly interface.

Keywords: access, magnetic card, card reader, code, access control
