Programación del sistema de automatización de préstamo de proyectores y registro de clases dictadas en la ESFOT

Abstract

The general system of the present project uses a server that hosts the software that is in charge of the interaction between the user and the electronic system for the loan or return of projectors and registration of the classes of the teachers. This program is presented in a Tablet that is embedded in the structure and makes the communication with the server through a Wi-Fi link, also uses a biometric device to verify the identity of users to allow entry into the general system; this fingerprint reader is connected to a router via a network cable.

On the other hand, the electronic system uses three control devices, a master Arduino (Arduino UNO) and two slave Arduinos (Arduinos Mega). The Arduino master is in charge of receiving loan and return requests for projectors from the server; additionally it is also in charge of sending all the information about the status of each locker, which is presented in the Tablet. To communicate with the server, it uses serial communication and for the communication with the Arduino slaves, it uses the I2C communication protocol.

Each slave is in charge of controlling 10 lockers. In each locker, there are two pilot lights, an infrared sensor, a magnetic lock and a magnetic sensor. To control the lighting of the pilot lights that work with 110v, are used relay modules that will switch depending on the data processed by the Arduino slave.

Finally, the respective tests of the whole program have been carried out to check the functionality of the system and all the parts that make it up.
