Implementación de un prototipo de red inalámbrica de control y supervisión de préstamos de equipos para el Laboratorio de Electrónica de la Facultad de Informática y Electrónica.

Abstract

A prototype wireless network was implemented for the control and supervision of electronic laboratory equipment loans from the Faculty of Information Technology and Electronics. The devices that make up the prototype were selected based on a study of their technical information, compatibility, cost, the ease of installation and the ease of interaction with the user. The transmitter module incorporates a PN532 / C1 board, which acts as a reader inducing electromagnetic waves towards the labels of near field communication (NFC) to obtain its code and transmit it by radiofrequency. The receiver module is responsible for taking the transmitted signals and forwards them to a computer through a USB connection. The computer also has a radio frequency identification (RFID) reader antenna that is responsible for monitoring the permanence of the equipment in the laboratory. From the performance tests carried out with the network prototype, an efficiency greater than 80% was determined in relation to the registry manually and 70% in relation to the registration through the existing software in the laboratory. From the equipment detection tests without registration, a 100% effectiveness was determined, which determines reliability in the prototype. The device consists of the transmission modules, reception and an RFID reader antenna. It has a software, linked to a database and designed in web pages that stores the information of equipment and the identification of students and facilitates interaction with users. It has the ability to emit sound warning messages when a device is taken out of the laboratory without the respective registration. It is advisable to extend the testing period of the network prototype, in order to identify possible modifications to the proposed design.
