Diseño e implementación de un sistema de control de temperatura y pH, con compartimiento de datos en tiempo real a través de la nube Talk2M, de la piscina municipal “Los Elenes” del cantón Guano.

Abstract

The purpose of this work was the design and implementation of a control system for temperature and pH, with data sharing in real time through the Talk2M cloud, to the municipal pool "Los Elenes" of the Guano Canton, a research work was carried out to obtain information on the optimal ranges of pH in a pool as well as temperature for the comfort of users, the development of the device was based on 3 stages, the first was the selection of the Hardware elements, the second the conditioning of signals and finally the software design. For the election of the hardware elements, technical characteristics and modern elements were considered to meet the system requirements. The second stage has to do with signal conditioning since it is important for the correct reading of the variables temperature and pH, since the programmable logic controller (PLC) can read values 0-10V. In the third stage, the programming was developed with the help of Logo Soft Comfort V8.3 creating an on-off control system, in addition to the use of the Talk2M platform and the Logo web editor software. From the results obtained, the dosage time of each of the liquid solutions (caustic soda and muriatic acid) was 1.8 minutes, the data taken by the sensors were displayed in the human machine interface (HMI) through the web Logo editor, and on the PLC screen, the homogenization time was also optimized thanks to a recirculation pump for the passing water of the pool. Bases and liquid acids are recommended to be used. in a way to avoid problems in the dosing of chemicals since when using granules, diluting it in water will change its concentration and can cause problems in the system.
