This paper proposes a design and construction of 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. An application was developed for each module in the Android Studio and NetBeans programming environments. 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% the time used in the traditional way. Significantly reduces command management time by 62.90%. There was no saturation in the network since the traffic generated only represented 2.76% of the router's capacity. It is recommended to hire a remote service to store the data. Keywords: wireless communication, data transmission, bandwidth, command, invoicing, wifi, system, modules. Resumen El presente artículo propone un diseño y construcción de un prototipo de red inalámbrica para la gestión y facturación de comandas en tiempo real, aplicado a la implementación de bares-restaurantes inteligentes. Está constituido por tres módulos que se comunican mediante tecnología Wi-fi. El módulo de administración proporciona la información necesaria para manejo de base de datos y facturas de usuario, el mismo que mediante el módulo de gestión utiliza dispositivos táctiles para generar pedidos, esta información es enviada directamente al módulo de preparación. La comunicación entre módulos se establece mediante consultas SQL para acceder a la base de datos creada en phpMyAdmin. Para cada módulo se desarrolló una aplicación en los entornos de programación Android Studio y NetBeans. La metodología aplicada en base a encuestas facilitó la determinación de necesidades y requerimientos del prototipo. Para la validación del sistema se realizaron pruebas sobre el funcionamiento íntegro y alcance de comunicación inalámbrica de este, estableciendo la distancia máxima de funcionamiento a los 33,75 metros, cumpliendo con las dimensiones del local en el que se implementó. Se verificaron tiempos de consulta de menú obteniendo que el sistema optimiza hasta un 86,00% los tiempos utilizados en la forma tradicional. Reduce notablemente el tiempo de toma de pedido en un 62,90%. No se presentó saturación de red ya que el tráfico generado representa el 2,76% de la capacidad del enrutador. Palabras clave: comunicación inalámbrica, transmisión de datos, ancho de banda, comanda, facturación, wifi, sistema, módulos.

Medical Accident

Transfusion monitoring and controlling system of wireless communication is designed for avoidance of medical accident due to inconsiderate care. This system is based on RS-485 bus protocol to build the communication network, consisting of master computer and slave computer. STM32F103R8T6 MCU is the core of the master computer, and MSP430F2132 MCU for slave computer. The wireless transmission of data between master computer and slave computer can be done by nRF905 wireless transceiver module. One new calculation of drop speed is used for better real-time displaying thereof. Provided that abnormal occurrence is during the transfusion, the transfusion tube will be closed by controlling order from system, in order to protect the patient.
