في السنوات الأخيرة أصبح مَصعَد الفراغ الهوائي هو خِياراً شائعاً في بيوتِنا والبنايات المنخفظة. يمثّل مَصعَد الفراغ الهوائي مَفهوم جَديد مُطوّر عن فِكرة استبدال الهواء المضغوط بالهواء المُفرّغ. إنّ مَصعَد الفراغ الهوائي قادر على نقل الأشخاص بين طوابق بناية بدون إستعمال لأيّ أحبال، أو أوزان، أو بكرات. في البحث الحالي تَمّ تركيب وتنفيذ نموذج لمنظومة مَصعَد فراغي كهرو هوائي بسيط ومُنخفض الكُلفة. نموذج نظام المصعَد يتألف من ثلاثة طوابق ويَرفع حُمولة 6 كيلوغرام. تَمّ تَوظيف المُسيطر المنطِقي القابل للبرمجة (PLC)، من سلسلة (LS\GLOFA-G7M-DR30U) ذو (16) مَدخل و(12) مَخرج ومُبرمج ببرامج المُخطط السُلمّي (Ladder)، للسيطرة المُؤتّمَتة الكامِلة على مَنظُومة المَصعَد. مِن المتوقع أن تَنتَشر فِكرة نِظام المَصعَد المُقترح على نحو واسع في البنايات السَكّنية الواطِئة.Pneumatic vacuum elevator (PVE) has become a popular choice for our homes and low-rise buildings in recent years. The Pneumatic vacuum elevator represents a new concept evolved from the idea of pressed air applied in the pneumatic elevator replaced by a vacuum air idea. The pneumatic vacuum elevator is able to transport people between building floors without using any cables, counterweight, or pulleys. A simple and low cost construction and implementation for an Electro-pneumatic vacuum elevator system prototype is presented in this paper. The elevator system prototype is constructed with three floors to elevate a maximum load of 6kg. Programmable Logic Controller (PLC) of (LS\GLOFA-G7M-DR30U) series with (16) inputs and (12) outputs programmed with Ladder diagram software is used for the fully automated the elevator system. The idea of the proposed elevator system may be predicted to be widely spread in the low-rise residential buildings
Web Supervision System of a Freight Elevator
Nowadays, automation and industrial control is an area in which there are innovations ev-
ery day in terms of process digitalization, equipment interconnection and human-machine
interaction, which results in a constant learning and adaptation to new technologies and
methodologies developed. With this comes the responsibility to keep systems robust
and prepared for eventual failures, while moving towards an increasing dependence on
remote communication between different controllers and different processes. This fact
leads to the need to create supervision and monitoring tools capable of detecting and
transmitting existing failures, while ensuring that the system continues to operate with
the same stability and performance.
Therefore, in this work it is proposed the development of a supervisory tool based
on industrial automation that has a fault detection component and a human-machine
interface in order to incorporate all the essential features of an industrial supervisor. Using
industrial programming languages for Programmable Logic Controllers, it was possible
to develop an algorithm that is based on inference mechanisms to identify potential faults
in the system, which are then transmitted to the user in an interface that can be accessed
either locally or remotely via the Web.Nos dias de hoje, a automação e controlo industrial é uma área onde existe todos os dias
inovações ao nível da digitalização de processos, da interconexão de equipamentos e na
interação Homem-máquina, o que resulta numa constante aprendizagem e adaptação
às novas tecnologias e metodologias desenvolvidas. Com isto, vem a responsabilidade
de manter os sistemas robustos e preparados para eventuais falhas, ao mesmo tempo
que se avança no sentido da cada vez maior dependência da comunicação remota entre
diferentes controladores e diferentes processos. Este facto leva a que tenham de ser criadas
ferramentas de supervisão e monitorização capazes de detetar e transmitir as falhas
existentes, enquanto se garante que o sistema continua em funcionamento garantindo a
mesma estabilidade e performance.
Assim, neste trabalho é proposto o desenvolvimento de uma ferramenta de supervisão
baseada em automação industrial que possua uma componente de deteção de falhas e
uma interface Homem-máquina de forma a incorporar todas as funcionalidades essenciais
de um supervisor industrial. Recorrendo a linguagens de programação industrial para
controladores lógicos programáveis, foi possível desenvolver um algoritmo que se baseia
em mecanismos de inferência para identificar potenciais avarias no sistema que são
posteriormente transmitidas ao utilizador numa interface que pode ser acedida quer
localmente, quer remotamente via Web

Analysis and full automation of an industrial system: functional optimization and vertical integration
This final project describes the entire automation procedure for a power & free conveyor and a double level conveyor belt. After a detailed description of both systems under mechanical and electrical perspectives, the thesis explains the implementation of an operating mode that complies with safety rules and ensures power saving as much as possible. Complete but intuitive HMI are realized; in addition, according to vertical integration, alarm diagnostic and database management are provide
Creación de Digital Twins para las estaciones 1 y 2 de la línea de ensamblaje automático FMS-200
La Industria 4.0 está siendo considerada como el cambio más moderno del paradigma
industrial gracias a la introducción del Internet de las Cosas. El sector secundario
actualmente invierte cuantiosas cantidades de tiempo y dinero en tratar de introducir
estas nuevas tecnologías en sus procesos, una de estas tecnologías son los llamados
Digital Twin o Gemelo Digital.
Esta memoria describe la confección paso a paso de un Digital Twin para una cadena

proceso necesario para unirlo a otro Gemelo dedicado a otra parte de la misma máquina
y su simulación simultánea, esto se logra haciendo uso de las herramientas
proporcionadas por el software de TIA Portal.ndustry 4.0 is becoming well stablished as a completely new change of the industrial
paradigm thanks to the introduction of the Internet of Things. Industries invest large
amounts of time and money in the shake of introducing these new technologies within
their processes, one of them is called Digital Twin.
This thesis guides step by step through the creation of a Digital Twin for a completely
automatic modular assembly line called FMS-200. The steps are explained for the

Rule-based system to detect energy efficiency anomalies in smart buildings, a data mining approach
The rapidly growing world energy use already has concerns over the exhaustion of energy resources andheavy environmental impacts. As a result of these concerns, a trend of green and smart cities has beenincreasing. To respond to this increasing trend of smart cities with buildings every time more complex,in this paper we have proposed a new method to solve energy inefficiencies detection problem in smartbuildings. This solution is based on a rule-based system developed through data mining techniques andapplying the knowledge of energy efficiency experts. A set of useful energy efficiency indicators is alsoproposed to detect anomalies. The data mining system is developed through the knowledge extracted bya full set of building sensors. So, the results of this process provide a set of rules that are used as a partof a decision support system for the optimisation of energy consumption and the detection of anomaliesin smart buildings.Comisión Europea FP7-28522

of the wall climbing robot in this project will be based on the pneumatic conceptthat is the
suction of air to make robot can move along the vertical glass. This project will require a
