Desarrollo de un sistema SCADA web para prevención de fugas de gases GLP

Abstract

Within the Mechanical Engineering career offered by the Salesian Polytechnic University on the South Campus of Quito Headquarters, it is essential for its students to carry out Foundry internships for the elaboration of molten aluminum parts. For which they have a laboratory that consists of an oven and a flute-type switchboard with a common gas outlet. The smelting laboratory has open and closed ventilation; however, in the event of a gas leak in the switchboard of large proportions, an accident can occur considering the high temperatures that the furnace reaches. That is why the development and implementation of a system that is capable of acting in the face of a gas leak according to a detection range of 10 to 15% of the explosiveness limit and that has the ability to be monitored and controlled from a "Supervisory Control and Data Acquisition" emitting alerts and notifications to the laboratory assistants in case of an incident occurs in the work area to intervene; that LPG gas leak prevention, its implementation until the tests carried out to validate its proper functioning. The first chapter covers the research problem, the solution is proposed, and the objectives of the project are established, the second chapter corresponds to the theoretical foundations necessary for the development of the LPG gas prevention system, the third chapter details the programming of the PLC, the electric force and control circuits, the design of the SCADA Web and the Augmented Reality application. While, in the fourth chapter, the results achieved with the project are appreciated, finally the fifth chapter establishes the conclusions reached after the completion of the previous stages and the recommendations for its proper functioning.
