Design of an identification system and automated access control using RFID technology for the University canteen of the UNSA

Abstract

An automated identification and control system has been developed to optimize the entry of students to the University dining room at the National University of San Agustin. The system of attendance and authentication is scalable, reliable and secure. The prototype consists of a master microcontroller with 2 slaves of RFID readers for a 13.56MHz frequency and works with two photoelectric proximity sensors, four actuators of pulse width modulation controlled servo motors (PWM) with a period of 20ms and a tape RGB smart led signaling. The purpose is to automate the entry of students so that long queues do not form while reporting on the attendance of students. Then, the proposal is to use a PWM control algorithm, which will run on the Atmega2560 master microcontroller, which is linked to a server. The database on the server verifies the identity and status of the student through a Java Netbeans graphical interface. The system is optimized to receive a rapid response and to function without line of sight of the tags.
