Diseño e implementación de un sistema automatizado con monitoreo vía web para una marmita para la elaboración de queso y un mezclador para la obtención de crema solar.

Abstract

The aim of this researching work, is to design and implementation of an automated monitoring system by web for a pot in order to make cheese and a mixer to get sun cream at the Polytechnic School of Chimborazo from Science Faculty, in Chemical Engineering School, laboratory of industrial processes, determining the controllable variables of these processes, which can describe and determine the best devices for the research. So in the stages of cooking and cooling, with specific analyzes a control circuit was performed with an HMI (Human Machine Interface) to access of instructions and return of results. For automation of machines, a control panel was designed, implementing a system for an automatic control of three-phase motors from 0.5 HP (Horse power) for a continuous improvement of the design and operation of pot and mixer, optimizing human resources, and improving the machines performance in the above stages. The internal monitoring system and web combined with the HMI, were implemented so that there is a human- machine interface, allowing the user to interact with the process, generating a real-time recording, the production process as well as the temperature values which are recorded in the process. The records generated were sent to an email, belonging to a responsible person in charge of laboratory operation, through the Simple Mail Transfer protocol. The result obtained after its operation, make optimization of material resources, human resources in a percentage of 20% in a group of at least 5 students, also it improves effíciency and equipment operation by 10% over its initial conditions, keeping hygiene and product quality or concentrates, strengthening safety when it operates, thus achieving automation equipment in 100% of operating steps. It advises to the lab operator; perform preventive maintenance of equipment periodically.
