Diseño y construcción de un prototipo de red inalámbrica para la gestión y facturación de comandas en tiempo real, aplicado en la implementación de bares-restaurantes inteligentes.

Abstract

This bachelor thesis is aimed at designing and building a wireless network prototype for the management and invoicing system of real-time commands, which is implemented to smart bar-restaurants. It is mainly made up of three modules that are interlinked through Wi-fi wireless technology. The administration module provides all the information required for commands management and invoices to the user through the management module that uses touch-based devices, this generated information is sent directly to the preparation module. The communication of each module is performed with SQL searches on the database server developed on phpAdmin. For the manipulation of the system three applications were carried out on the programming environments Android Studio and NetBeans. The applied methodology is based on surveys that determine the prototype needs and requirements. For prototype validation, a series of tests were conducted on the integral operation and wireless communication range of the latter, establishing the maximum operating distance at 33.75 meters, so that the operation did not present malfuncions due to the Location dimensions are within range. Menu query times were verified obtaining that the system optimizes in 86.00% and 56.73% the minimum and maximum times used in the traditional way. Significantly reduces command management time by 14.54% and 62.90%. There was no saturation in the network since the traffic generated only represented 2.76% of the router's capacity. For better data management, it is recommended to use a remote server on cloud-based services instead of a local network.
