Konstruktion och implementering av mobil prototyp: The Lovebomb / Construction and implementation of a mobile prototype: The LovebombKylin, Oskar, Wibrand, John January 2002 (has links)
<p>The idea for the thesis “Construction and implementation of a mobile prototype; The Lovebomb” originates from doctoral candidates Rebecca Hansson and Tobias Skog from PLAY Research Group at the Interactive Institute in Gothenburg. The object of the master thesis is to construct two working LoveBomb prototypes, one mother console belonging to the LoveBomb and blueprints for both. The LoveBomb (the picture to the right shows a possible design) is intended to encourage people to express themselves emotionally when situated amongst strangers in public spaces. Two buttons control the device, which contains a radio transceiver. By pushing the buttons the user can either send a happy message or a sad message. The LoveBombs in the vicinity receive the sent message and lets its user know which message that has been received by vibrating either a sad irregular pulse or a happy continuous pulse. While vibrating the LoveBomb send out a confirm message. The confirm message can only be received by a LoveBomb which has recently sent out a message. After receiving a confirm message the LoveBomb conveys this to the user by turning on a red LED (light emitting diode) and letting the LED shine for about half a minute. During this time the LoveBomb can only receive messages. If it receives a message, during these 30 seconds, the LED is turned off and the prototype starts vibrating according to the received message. Should a LoveBomb which has sent a message fail to receive a confirm message it conveys this to the user by turning on and off the LED three times. After this the prototype is ready to send another message. The picture below shows a state diagram of the LoveBomb. The mother console registers all the communication between the LoveBomb, by pushing a button the user can see how many happy respectively sad messages that has been sent. Our workstarted with the doctoral candidates communicating their thoughts and wishes concerning the prototype to us. We organized this information into a requirement specification. We started the development of the Lovebomb and the belonging mother console by selecting a suitable micro controller. We choose PIC16C84 from Microchip but changed later to its successor PIC16F84, because the latter was easier to get a hold of. The micro controller controls all the other components. When we knew how to program the micro controller, we started working with a transceiver, suggested by the doctoral candidates, DR3001 from RFM. After establishing a meaningful communication between two micro controllers connected with on transceiver each, this was the hardest and most important part, we began working with not so vital component such as diodes, vibrators and buttons. When we were finished with the implementation and construction we examined the prototype and compared it to the requirement specification. To our satisfaction the prototype did not differ a lot from the requirements and the existing differences were improvements from the original idea. During the development process both of us learned a lot about assembler programming, electrical engineering and radio communication.</p>

Produktutveckling & Digital Konstruktion av Plasmaskärande CNC-Maskin / Product developement & Digital construction of Plasma Cutting CNC-MachineHidling, Filip, Nilsson, Kristoffer January 2024 (has links)
Problemet som arbetet förhåller sig till är Blekinge Tekniska Högskolas maskinlabs avsaknad av en snabb och precis bearbetningsmetod för att skära ut detaljer i plåt. Syftet med arbetet är således att med vetenskapliga produktutvecklingsmetoder konstruera en plasmaskärande CNC-maskin till maskinlabbet. Arbetet begränsas av en kravspecifikation som förväntas nås. Dessa krav är att budgeten till den slutgiltiga konstruktionen inte överstiger 20.000:- SEK. Konstruktionens yttermått överstiger inte 1200x1200 mm, och går att förflytta på plant underlag. Ingående delar går att tillverka i en 3 – axlad CNC maskin, svarv eller fräs alternativt utgörs av standardkomponenter. Plasmaskärarens munstycke behöver vara rörlig i tre dimensioner, där höjdled medges rörlighet från 0 - 40 mm. Precisionen för CNC-maskinen är minst 0,1 mm. Ett arbetsbord som är motståndskraftigt mot brännarens genomskärning skall konstrueras. Kablar från motorer och plasmaskärare hanteras på ett sätt sådant att de inte stör maskinen under drift. Metoderna som använts under produktutvecklingsprocessen baseras på ett flertal steg med poängsättningsmatriser där olika lösningar ställs mot varandra och utvärderas. För modellering av systemets komponenter har mjukvaruprogrammet Autodesk Inventor använts. Vid beräkning av belastningsfall har stress Analysis i Inventor använts. Beräkningar har också utförts analytiskt och jämförts med de erhållna från Inventor. Arbetet resulterade i ritningsunderlag, BOM-lista och digital konstruktion för en 3-axlig plasmaskärande CNC-maskin. Resultatdelen består även av beräkningar som påvisar konstruktionens hållfasthet, samt maskinens precision och hastighet. Dessa resultat bedöms uppfylla alla krav utifrån den givna kravspecifikationen. Utformningen av CNC-maskinen visade sig vara omfattande. Avgränsningar som gjordes med avseende på detta var att fokusera produktutvecklingsprocessen på maskinens övergripande utformning. Detta för att de element av maskinen som ansågs vara mer kritiska för maskinens funktion hamnade i fokus. / The problem the work relates to is the lack of a fast and precise processing method for cutting out details from sheet metal at Blekinge Institute of Technology’s machine lab. The purpose of the work is thus to construct a plasma cutting CNC machine for the machine lab using scientific product development methods. The work is limited by requirements and specifications that are expected to be met. These requirements are that the budget for the final construction does not exceed 20.000 SEK. The outer dimensions of the construction do not exceed 1200x1200 mm and can be moved on a flat surface. Parts for the construction can be manufactured in a 3-axis CNC machine, lathe or mill. Alternatively, purchased parts are composed of standard components. The plasma cutter’s nozzle needs to be movable in three dimensions, where the height is allowed mobility from 0 - 40 mm. The precision of the CNC machine is at least 0.1 mm. The work table is required to be resistant to the torch cutting through. Cables from the motors and plasma cutter are handled in such a way that they do not disturb the machine in operation. The methods used during the product development process are based on several steps with scoring matrices where different solutions are compared and evaluated. For modeling of the system’s components the software Autodesk Inventor has been used. For calculations of load cases, the Stress Analysis Tool in Inventor was used. Calculations have also been performed analytically and compared with those obtained from Inventor. The work resulted in drawing documents, BOM list and digital construction for a 3-axis plasma cutting CNC machine. The result part also consists of calculations that demonstrate the construction’s strength, as well as the machine’s precision and speed. These results are judged to meet all requirements based on the given specification. The design of the CNC machine turned out to be extensive. The scope of the work was therefore limited to focus the product development process on the machine’s overall design so that the elements of the machine that were considered more critical for the machine’s function came into focus.

Automation and Information Approaches to Support Maintenance and Production Management in the Construction IndustryParisi, Fabio 18 April 2023 (has links)
[ES] La industria de la construcción es un amplio sector industrial que abarca desde el diseño y la gestión de grandes infraestructuras como puentes hasta la construcción de viviendas civiles. Es mundialmente reconocido como un sector impulsor fundamental del Producto Interno Bruto, pero también se encuentra entre los de menor rendimiento y retraso en la adopción y explotación de mejoras tecnológicas. Estas limitaciones están induciendo a las partes interesadas a tomar prestadas e integrar muchas mejoras de otros campos industriales en el sector. Esta tendencia de digitalización se está extendiendo a lo largo de todo el ciclo de vida del proceso de construcción e identifica un enfoque desafiante debido al cambio de paradigma necesario de los sistemas físicos a los ciberfísicos. El concepto Industria 4.0 impulsó esta tendencia por lo que tanto en la academia como en la industria de la construcción se ha concretado como Construcción 4.0. Toma prestada de la Industria 4.0 la adopción de muchas tecnologías habilitadoras clave como Internet de las Cosas, Inteligencia Artificial y Fabricación Aditiva. Esta tesis investiga specíficamente esta integración tecnológica, centrándose en la aplicación de tales tecnologías habilitadoras en el campo de la construcción y considerando diferentes etapas en el ciclo de vida en diferentes tipologías de infraestructura. A partir de una investigación bibliográfica sobre sistemas inteligentes "holísticos" en la construcción de Edificios Inteligentes, a la manera de Gemelos Digitales, se estudia la influencia y la aplicación de tecnologías habilitadoras y herramientas TIC operativas relacionadas, como Internet de las Cosas y Big Data, desde una perspectiva de todo el ciclo de vida de las construcciones. Se estudia la fase de mantenimiento de grandes infraestructuras en materia de seguridad estructural y detección de fallos, mediante el desarrollo de un método de detección de daños en puentes ferroviarios de celosía metálica mediante inteligencia artificial. Luego se presenta una innovadora tecnología de fabricación aditiva para construcciones de gran altura. Consiste en una mejora de la tecnología de las grúas torre estándar con una extrusora personalizada, mientras que todo el sistema está controlado por un agente de inteligencia artificial.
Concluimos que la Construcción 4.0 aún se encuentra en su etapa embrionaria. Se pueden obtener resultados más avanzados en la implantación tecnológica sobre infraestructuras existentes para su gestión de operación y mantenimiento debido al enfoque relacionado principalmente con la sensorización y análisis de datos. La innovación en la fase integrada de diseño/construcción sigue siendo más desafiante, debido a la necesidad de un paradigma completamente nuevo e innovaciones industriales en muchos campos diferentes. / [CA] La indústria de la construcció és un ampli sector industrial que abasta des del disseny i la gestió de grans infraestructures com a ponts fins a la construcció d'habitatges civils. És mundialment reconegut com un sector impulsor fonamental del Producte Intern Brut, però també es troba entre els de menor rendiment i retard en l'adopció i explotació de millores tecnològiques. Aquestes limitacions estan induint a les parts interessades a amprar i integrar moltes millores d'altres camps industrials en el sector. Aquesta tendència de digitalització s'està estenent al llarg de tot el cicle de vida del procés de construcció i identifica un enfocament desafiador a causa del canvi de paradigma necessari dels sistemes físics als ciberfísics. El concepte Indústria 4.0 va impulsar aquesta tendència pel que tant en l'acadèmia com en la indústria de la construcció s'ha concretat com a Construcció 4.0.

Aquesta tesi investiga específicament aquesta integració tecnològica, centrant-se en l'aplicació de tals tecnologies habili-
tants en el camp de la construcció i considerant diferents etapes en el cicle de vida en diferents tipologies d'infraestructura. A partir d'una investigació bibliogràfica sobre sistemes intel·ligents "holístics" en la construcció d'Edificis Intel·ligents, a la manera de Bessons Digitals, s'estudia la influència i l'aplicació de tecnologies habilitants i eines TIC operatives relacionades, com a Internet de les coses i Big Data, des d'una perspectiva de tot el cicle de vida de les construccions. S'estudia la fase de manteniment de grans infraestructures en matèria de seguretat estructural i detecció de fallades, mitjançant el desenvolupament d'un mètode de detecció de danys en ponts ferroviaris de gelosia metàl·lica mitjançant intel·ligència artificial. Després es presenta una innovadora tecnologia de fabricació additiva per a construccions de gran altura. Consisteix en una millora de la tecnologia de les grues torre estàndard amb una extrusora personalitzada, mentre que tot el sistema està controlat per un agent d'intel·ligència artificial. Concloem que la Construcció 4.0 encara es troba en la seua etapa embrionària. Es poden obtindre resultats més avançats en la implantació tecnològica sobre infraestructures existents per a la seua gestió d'operació i manteniment degut a l'enfocament relacionat principalment amb la sensorització i anàlisi de dades. La innovació en la fase integrada de disseny/construcció continua sent més desafiadora, a causa de la necessitat d'un paradigma completament nou i innovacions industrials en molts camps diferents. / [EN] The construction industry is a wide industrial sector ranging from the design and management of major infrastructures, such as bridges, to civil dwelling construction. It is worldwide acknowledged as a fundamental driving sector for the Gross Domestic Product, but it is also among the less performing and delayed ones in the adoption and exploitation of technological improvements. These limitations are inducing stakeholders to borrow and integrate many enhancements from other industrial fields into the sector. This digitalization trend is spreading through the entire life cycle of the construction process and identifying a challenging approach because of the paradigm shift needed from physical to cyber-physical systems. The Industry 4.0 concept boosted this trend so that both in the academy and in the construction industry it has been specified as Construction 4.0. It borrows from the Industry 4.0 the adoption of many key enabling technologies such as Internet of Things, Artificial Intelligence and Additive Manufacturing. This thesis investigates specifically this technological integration, focusing on the application of such enabling technologies in the construction field and considering different stages in the life cycle in varying infrastructure typologies. Starting from a literature investigation on "holistic" intelligent systems in Intelligent Buildings construction, in a Digital Twin fashion, the influence and the application of enabling technologies and related operative ICT tools such as Internet of Things and Big Data are studied, from a perspective of the whole constructions' life cycle. The maintenance phase of major infrastructures is studied concerning structural safety and fault detection, by developing a method to detect damages in railway steel truss bridges via artificial intelligence. An innovative additive manufacturing technology for high-rise constructions is then presented. It consists of an improvement with a custom extruder of standard tower crane technology, while the whole system is driven by an artificial intelligence agent. We conclude that Construction 4.0 is still at its embryonic stage. More advanced results are obtainable for the operation and maintenance management of existing infrastructures because of the already mature approach related to sensorization and data analysis. Innovation in the design/construction phase remains more challenging,because of the need for a completely new paradigm and industrial innovations in many different fields. / Parisi, F. (2023).

Effektivisering av ritningshantering med hjälp av programmet DDR - Databas för Detaljer och Ritningar / Streamlining the process of handling construction drawings with the application DDR - Database for Details and DrawingsGlemryd, Frida, Lekeby, Niclas January 2013 (has links)
Att spara tid och resurser är något som är av stor vikt i dagens byggbransch. Ju snabbare ett arbete utförs desto mer pengar tjänar företaget. I detta examensarbete har författarna tittat på effektivisering av ritningshanteringen i olika delar av byggbranschen. Att kunna hitta bland ritningarna på ett enklare sätt och att slippa sortera ut gamla ritningar när nya kommer in, är något som skulle förenkla ritningshanteringen och snabba upp tempot. Författarna har tittat på programmet DDR – Databas för Detaljer och Ritningar, som de anser kan förenkla ritningshanteringen. Under arbetets gång har intervjuer hållits med olika personer inom byggbranschen för att se förbättringsmöjligheter och nyttan av ett sådant program. Resultatet av arbetet visar att programmet DDR skulle göra mest nytta på byggarbets-platser och inom förvaltning då det är inom dessa områden som ritningshantering utförs mest. Programmet DDR kan förkorta tiden det tar att bläddra bland ritningar med uppskattningsvis 25 % enligt de intervjuade på byggarbetsplatserna, vilket skulle kunna innebära en markant skillnad i det dagliga arbetet. Om övergång sker helt till digitala ritningar 1 skulle behovet av att sortera ritningar elimineras och ännu mer tid kan sparas. För att göra så stor skillnad som möjligt på dagens marknad måste de förbättringar som framkommit under intervjuerna utvecklas till programmet DDR. Som det är idag saknas många funktioner vilket gör att konstruktionsföretagen inte vill använda programmet DDR på grund av avsaknaden av möjlighet att lägga in egna detaljer. Förvaltning anser bland annat att flera viktiga mät- och ritfunktioner saknas i programmet DDR för att vilja använda det. Kalkylerare och kommuner ser ingen framtid alls för programmet DDR inom deras verksamhet. Undervisning på högskola och i produktion på byggarbetsplatser anser att bland annat zoomningen och panorering måste göras enklare, trots detta är de intresserade av att använda programmet DDR. / Saving time and resources is something that is very important in construction business today. The faster a work can be done the more money a company can make. In this degree project the authors have looked at the process of handling construction drawings in different parts of the construction industry. To be able to find the construction drawings in an easier way and not have to sort out old construction drawings when new arrive is something that may simplify and speed up the process. The authors have looked at the application DDR – Database for Details and Drawings, which they consider could simplify the process of handling construction drawings. During this degree project, interviews have been done with different people in the construction industry to see possibilities of improvement and benefits of the application DDR. The result of the degree project shows that this application would make the most difference on construction sites and within management of buildings since these are the ones that handle construction drawings on a daily basis. Application DDR can shorten the time used for handling of construction drawings by approximately a 25% decrease according to the interviewed at the construction sites; this would make a great difference in the daily work. If they only use digital construction drawings, the needs to sort out old construction drawings when new ones arrived, will be eliminated and more time can be saved. To do as much of a difference as possible on today’s market the improvements that have emerged during the interviews have to be developed to the application DDR. As it is today there are many features that are missing which make that the construction companies won’t use the application due to the lack of possibility to add details on their own. Management of buildings considers that there are several important functions such as measuring and drawing that are missing to use the application DDR. Within calculation engineering and municipalities there is no future for the application DDR. Education at college and in the production of construction sites consider that zooming and panning must be made simpler, despite this they are interested in using the program DDR.

Softwareentwicklung ECM/WCM im Spannungsfeld KMUs–GroßunternehmenSchwarz, Oliver, Kowalewski, Christian 03 January 2020 (has links)
Der BIM-Standard hat in den letzten Jahren viel Bewegung in die Softwarelandschaft gebracht. Der Wunsch und die Notwendigkeit, Daten aus der EMC Landschaft mit den digitalen Daten der Planung und dem aktuellen Progress auf den Baustellen zu verbinden, stellt hier einen besonderen Motor dar. Die digitale Bauakte – nur ein Traum? Unternehmen unterschiedlichster Größe und Ausrichtung begleiten durch Ihre Tätigkeiten einen Neu- bzw. Umbau von der Idee bis zur Realisierung. Die Lösungsansätze bzw. Lösungen der Digitalisierung in den verschiedensten Ausprägungen, Tiefen und Teilbereichen existieren. Eine Lösung, die von den KMUs bis hin zu den Konzernen genutzt wird, haben wir aus dem Blickwinkel der Planer, Betreiber und Montageunternehmen im industriellen Anlagenbauumfeld (Industrie- und Produktionsanlagen aller Art) nicht gefunden. Die Lösung von inactio und ESZETT schaut aus zwei unterschiedlichen Blickwinkeln auf die Kunden. Die Abbildung 1 reißt das Spannungsfeld ein wenig an. inactio/eebos begleitet Ihre Kunden im Umfeld von onbase, SAP und digitalen Archiven. ESZETT kommt mit ihren Erfahrungen der Planungswelten, VR-Systemen und dem WCM-System bee aus der Planungs- und Montagebegleitung. Der Wunsch, mit einer kleinen Lösung zu beginnen (KMU), die bei den einzelnen Unternehmen für ihre Belange genutzt werden kann, hin zu der Vernetzung und der Möglichkeit des Einbindens dieser ‚Inseln‘ in einem Gesamtprojekt mit allen technischen Möglichkeiten und Verknüpfungen, soll kein Traum bleiben.
