Δημιουργία βιβλιοθήκης ηλεκτρικών συμβόλων στο AutoCAD για τη σχεδίαση ασθενών ρευμάτων και αυτοματισμών στις εσωτερικές ηλεκτρικές εγκαταστάσεις και τυπική εφαρμογή της

Κουζαπάς, Ανδρέας 13 September 2011 (has links)
Σκοπός αυτής της διπλωματικής εργασίας είναι η δημιουργία βιβλιοθήκης ηλεκτρικών συμβόλων, στο σχεδιαστικό λογισμικό AutoCAD, ώστε να καλύψει το κενό που παρουσιάζει η κανονική έκδοση του προγράμματος, η οποία δεν ενσωματώνει τα ηλεκτρικά σύμβολα που πρέπει να χρησιμοποιούνται στην Ελλάδα. Η βιβλιοθήκη περιέχει τα σύμβολα ασθενών ρευμάτων και αυτοματισμών τα οποία πρέπει να χρησιμοποιούνται σήμερα στα ηλεκτρολογικά σχέδια από όλους όσους ασχολούνται με το θέμα. Το πρότυπο για τα ηλεκτρικά σύμβολα που χρησιμοποιείται στην παρούσα διπλωματική εργασία, είναι το πρότυπο ΕΛΟΤ EN 60617. Τα ηλεκτρικά σύμβολα τα οποία είναι βασισμένα σε πρότυπα, πρέπει πάντα να τηρούν κάποιους σχεδιαστικούς κανόνες. Η κανονική έκδοση του προγράμματος AutoCAD δεν έχει καθόλου βιβλιοθήκες ηλεκτρικών συμβόλων, και για κάποιον ο οποίος χρειάζεται τα ηλεκτρικά σύμβολα του προτύπου ΕΝ 60617, πρέπει αναγκαστικά να τα αγοράσει μέσω διαδικτύου. Το πρώτο κεφάλαιο της διπλωματικής εργασίας ασχολείται με την τυποποίηση και τα πρότυπα. Γίνεται αναφορά στους οργανισμούς τυποποίησης και στις ηλεκτροτεχνικές επιτροπές, που αφορούν την Ελλάδα. Τέλος γίνεται μια αναφορά στα ηλεκτρικά σύμβολα που πρέπει να χρησιμοποιούνται σήμερα. Το δεύτερο κεφάλαιο ασχολείται με την περιγραφή του σχεδιαστικού προγράμματος AutoCAD. Γίνεται περιγραφή των λειτουργιών του AutoCAD και της χρήσης των εργαλείων που πρέπει οπωσδήποτε να γνωρίζει κάποιος για να μπορεί να σχεδιάζει ηλεκτρικά σύμβολα τα οποία θα χρησιμοποιούνται στην δημιουργία βιβλιοθήκης και για τον σχεδιασμό ηλεκτρολογικού σχεδίου. Το τρίτο κεφάλαιο ασχολείται με την ακριβή περιγραφή του σχεδιασμού των ηλεκτρικών συμβόλων, δηλαδή τη μεταφορά του ηλεκτρικού συμβόλου από το χαρτί του προτύπου ΕΝ 60617 στον υπολογιστή. Γίνεται όσο το δυνατόν καλύτερος σχεδιασμός, τηρώντας κατά γράμμα τις σχεδιαστικές απαιτήσεις του προτύπου. Το τέταρτο κεφάλαιο ασχολείται με τον τρόπο προσαρμογής του μενού του προγράμματος AutoCAD στις ανάγκες της παρούσας διπλωματικής εργασίας. Επίσης γίνεται αναφορά στον τρόπο δημιουργίας της βιβλιοθήκης των ηλεκτρικών συμβόλων ο οποίος απαιτεί την δημιουργία κατάλληλου κώδικα. Το πέμπτο κεφάλαιο ασχολείται με τις Εσωτερικές Ηλεκτρικές Εγκαταστάσεις ασθενών ρευμάτων και αυτοματισμών. Γίνεται μια αναφορά στο τι περιλαμβάνει η κάθε ηλεκτρική εγκατάσταση παρουσιάζοντας το και με φωτογραφικό υλικό. Τέλος το έκτο κεφάλαιο ασχολείται με την τυπική εφαρμογή της βιβλιοθήκης των ηλεκτρικών συμβόλων τα οποία έχουν κατασκευαστεί στην παρούσα διπλωματική εργασία. Χρησιμοποιείται δηλαδή η κάτοψη μιας οικίας στην οποία προστίθεται και το σχέδιο των εγκαταστάσεων ασθενών ρευμάτων και αυτοματισμών. / The purpose of this thesis is to create a library of electrical symbols, which will be designed by the AutoCAD software, to fill in the gap that the normal version has. The normal version does not include the electrical symbols that must be used in Greece. The library contains symbols of weak currents and automations to be currently used in electrical drawings by all people who are related to that subject. The standard of the electrical symbols used in this thesis is based on the standards of ΕΛΟΤ ΕΝ 60617. These electrical symbols that are based on standards must always follow some basic design rules. The standard version of AutoCAD has no electrical symbol libraries, so someone who needs these symbols of EN 60617, then he must necessarily buy them online or by specific WebPages. The first chapter of this thesis deals with the standardization and standards. Some standardizations and the Electro‐technical Commission, relating to Greece, are also mentioned. Furthermore, there is a reference to the electrical symbols to be used nowadays. The second chapter deals with description of the design program called AutoCAD. There is a description of the functions of AutoCAD and how to use the tools of it, so that anyone who is familiar to those can be able to design electrical symbols that are used to create the library and the electrical plan. The third chapter is about an accurate description of the design of electrical symbols namely the transfer of the electric symbol from the paper based on the EN 60 617 to the computer. It is possible better design according to the requirements of the standard. The fourth chapter refers to how to customize the menu of AutoCAD to the needs of this thesis. Additionally, it refers on how to create the code of such a library with electric symbols. The fifth chapter deals with the internal low voltage electrical installations and automation. It refers to what’s involved in electrical installation and that is presented by photos. Finally, the sixth chapter deals with the formal application of the library of electrical symbols which have been built in this thesis. These symbols will be implemented in housing after the electrical plan of the house is created.

Nosso objetivo foi o de avaliar como ocorre a transferência de informação dos elementos geométricos entre estes sistemas e como as dificuldades de interoperabilidade entre os mesmos podem afetar a fidedignidade dos modelos físicos gerados a partir dos modelos virtuais originais. Por isto elaboramos a hipótese que afirma que o uso de diferentes tipos de sistemas CAD e de prototipagem rápida resulta em diferentes níveis de sucesso na transferência de informações entre os mesmos, devido ao grau de precisão de cada sistema. Apesar do variado grau de precisão, estes sistemas produzem modelos físicos digitais com a representação satisfatória em relação ao modelo virtual original, portanto sem necessidade de retrabalho. A partir da realização de seis experimentos elaboramos uma análise comparativa entre os aspectos formais resultantes da modelagem e da prototipagem de um mesmo projeto arquitetônico em diferentes tipos de sistemas CAD: Revit, AutoCAD e FormZ. Os modelos CAD foram importados pelos softwares de prototipagem rápida ReplicatorG da Makerbot e Zprint da ZCorporation para serem produzidos por suas respectivas impressoras tridimensionais, pelo processo de adição de camadas. Os resultados obtidos a partir da experimentação foram avaliados em duas etapas: a primeira constatou que é possível obter a interoperabilidade integral das geometrias do modelo entre os diferentes sistemas CAD e os diferentes softwares de prototipagem rápida utilizados. A segunda etapa demonstrou que os sistemas apresentam diferentes graus de precisão, observados principalmente no momento de importação e reprodução das superfícies curvas e complexas do modelo. Ao final desta dissertação, sugerimos um conjunto de recomendações para facilitar a utilização destas ferramentas digitais por parte dos arquitetos, para que as mesmas contribuam agilizando e tornando mais precisas as tomadas de decisão, durante o processo de projetação. Reduz-se, assim, a probabilidade de retrabalho do modelo virtual original, após sua importação por meio dos sistemas de prototipagem rápida. _______________________________________________________________________________________________________________________________ ABSTRACT / In this Master research work we develop a study about the application of different types of computer aided design (CAD) and rapid prototyping systems in the process of architectural design. Our goal is to assess how the transfer of geometric elements information between these systems occurs and also the difficulties of interoperability between them can affect the reliability of physical models generated from the original virtual models. Therefore we developed the hypothesis that the use of different types of CAD and rapid prototyping systems results in different levels of successful transfer of information between them, due to the accuracy of each system. Although the varied degree of precision, these systems produce digital physicals models with the satisfactory representation in relation to the original virtual model, so there is no need for rework. Upon completion of six experiments we performed a comparative analysis of the resulting formal aspects of modeling and prototyping of the same architectural design in different CAD systems: Revit, AutoCAD and FormZ. The CAD models were imported by the software for rapid prototyping of ReplicatorG MakerBot and Zprint of ZCorporation to be produced by their respective three-dimensional printers, in the process of adding layers. The results from the trial were evaluated in two stages: the first one found it possible to achieve full interoperability of the model geometry between different CAD systems and different software used for rapid prototyping. The second stage showed that the systems have varying degrees of precision, mainly observed at the time of importing and reproduction of curved and complex surfaces model. At the end of this Dissertation, we suggest a set of recommendations in order to make it easier for the architects to use these digital tools, so that the same ones may contribute to accelerate it and also, to make it possible for these professionals to get more accuracy, when making up their minds, during the entire process. Thus, the need to rework the proposed model after importing it to the rapid prototyping systems is reduced.

An engineered design of a diffractive mask for high precision astrometry

Dennison, Kaitlin, Ammons, S. Mark, Garrel, Vincent, Marin, Eduardo, Sivo, Gaetano, Bendek, Eduardo, Guyon, Oliver 27 July 2016 (has links)
AutoCAD, Zemax Optic Studio 15, and Interactive Data Language (IDL) with the Proper Library are used to computationally model and test a diffractive mask (DiM) suitable for use in the Gemini Multi-Conjugate Adaptive Optics System (GeMS) on the Gemini South Telescope. Systematic errors in telescope imagery are produced when the light travels through the adaptive optics system of the telescope. DiM is a transparent, flat optic with a pattern of miniscule dots lithographically applied to it. It is added ahead of the adaptive optics system in the telescope in order to produce diffraction spots that will encode systematic errors in the optics after it. Once these errors are encoded, they can be corrected for. DiM will allow for more accurate measurements in astrometry and thus improve exoplanet detection. The mechanics and physical attributes of the DiM are modeled in AutoCAD. Zemax models the ray propagation of point sources of light through the telescope. IDL and Proper simulate the wavefront and image results of the telescope. Aberrations are added to the Zemax and IDL models to test how the diffraction spots from the DiM change in the final images. Based on the Zemax and IDL results, the diffraction spots are able to encode the systematic aberrations.
