Recopilación de aspectos diversos sobre comunicación, análisis de transmisión de datos y protocolos, análisis de protocolos de comunicación de ordenes y optimización de tiempo de ocupación de canal. En el Capítulo 2 se presentan algunos conceptos generales, empezando por formalizar lo que entendemos por sistemas complejo s, y tratando temas...

Lección Inaugural de la Escuela Técnica Superior de Ingeniería Informática de la Universidad de Sevilla. Curso Académico 2001-2002. Partiendo de la raíz griega de la palabra técnica "techné" (arte, oficio, habilidad) y la raíz indoeuropea "teks" (tejer, inventar), se lleva a cabo un estudio, desde estas variadas acepciones, en torno a la...

SISTEMA PARA LA MEDIDA DE RETRASOS EN INSTRUMENTACION DISTRIBUIDA. SISTEMA PARA LA MEDIDA DE RETRASOS EN INSTRUMENTACION DISTRIBUIDA, QUE PERMITE DETERMINAR LOS RETRASOS EN LA TRANSMISION QUE AFECTAN A LOS DATOS OBTENIDOS MEDIANTE SISTEMAS DE INSTRUMENTAC

Se presenta un estudio sobre seguridad en la transmisión de comandos en sistemas complejos. El objetivo principal es garantizar tasas de error menores de los límites recomendados por las organizaciones internacionales, manteniendo la ocupación canal de comunicación lo más bajo posible. Se analizan dos métodos de aumentar la seguridad y se...

Solar energy is one of the most promising sources of energy that could be used to address distributed supply problems. Global warming and decarbonization are significant global concerns, particularly for countries that are not fossil fuel providers. This paper presents a study focused on Spain, a country with a favorable location with respect...

The energy transition from fossil fuels to carbon-free sources will be a big challenge in the coming decades. In this context, the long-term prediction of energy demand plays a key role in planning energy infrastructures and in adopting economic and energy policies. In this article, we aimed to forecast energy demand for Spain, mainly employing...

The large amount of sensors in modern electrical networks poses a serious challenge in the data processing side. For many years, spectral analysis has been one of the most used approaches to extract physically meaningful information from a sea of data. Fourier Transform (FT) and Wavelet Transform (WT) are by far the most employed tools in this...

Currently, there are many technologies available to automate public utilities services (water, gas and electricity). AMR, Automated Meter Reading, and SCADA, Supervisory Control and Data Acquisition, are the main functions that these technologies must support. In this paper, we propose a low cost network with a similar architecture to a static...

Mejora de "bus de campo" mediante la incorporación de conductores de tierra adicionales.El objeto de la presente invención consiste en la mejora de "buses de campo" incorporando conductores de tierra adicional en el cable "bus" utilizado para comunicacion

The study of the existing relationship between a measurement error and the time elapsed since that measurement was taken in the field, a period of time which we will call the datum age, will allow us to learn about its behavior in a supervisory control and data acquisition (SCADA) system. This study has allowed us to know that, in the case of...

This paper presents the use of ESTELLE, a formal description technique, as a method to calculate automatically the performance of telecontrol protocols in SCADAsystems. Some specific primitives are added to the ESTELLE description language in order to achieve that goal. As an example, we analyze the performance of a telecontrol protocol. The...

The need to provide communication among the various computers that make up supervisory control and data acquisition (SCADA) systems is encountered more and more frequently. This equipment is usually from various generations, technologies, and manufacturers. Much effort has been made to define a set of standard protocols for both center-remote...
