Simulación de un dispositivo de control de acceso y comunicación para las oficinas de docencia de la dirección – ESFOT

Abstract

This project is executed by the design and simulation of an access control and communication system between the professor and the student, for that is necessary to use RFID technology, a Raspberry Pi 2b microcontroller and an RC522 reader, which allows the reading of TAG ID to authenticate the teacher and, in that way, validate or deny the opening of the door. On the other hand, for the communication between the professor and the student, an open-source software from an Asterisk telephone exchange was used that will allow communication through audio and video codecs and the SIP protocol between different emulators of IP telephones called softphones. For all of the above mentioned, two UNIX-type operating systems were used, the first an Ubuntu 20.04 that works as a server where several services are installed such as apache, phpMyadmin, MYSQL, and Asterisk, useful in creating users for both the TAGs of ID, as well as the users for the telephone exchange; and a Linux Debian 10.9 operating system, where the code for the operation of the access control system was created.
