Construcción de un prototipo de red de nodos inteligentes para supervisar la calidad y niveles del agua potable en los tanques de reserva de EP-EMAPAR.

Abstract

The objective of the research was to build a network prototype of intelligent nodes for the supervision of the quality and levels of potable water in the reserve tanks of the Public Company of Potable Water Riobamba. With a bibliographic review of existing monitoring systems and the needs of water treatment, a wireless communication with star topology was designed to measure physical and chemical parameters, works under the standards INEN 1108 and those established by the Ministry of the Environment of Ecuador. The information emitted by the sensors is processed by an Arduino UNO development card and sent through the GSM / GPRS network by the TCP / IP protocol to a historical database, it can issue warning messages when levels not permitted in water quality are detected. A web page was developed in ASP.NET with the programming language C Sharp, different levels of users can access it to monitor and visualize in a graphic and numerical form the information collected. An experimental review was used to validate the operation of the network prototype with ten samples and comparing the information obtained with results provided by the Water Quality Laboratory of Escuela Superior Politécnica de Chimborazo. It was found that the prototype maintains PH errors of more less 0.1 pH and conductivity of more less (1) one microsecond per centimeter, thus demonstrating that the prototype implemented is competitive with commercial equipment of similar characteristics. It is concluded that the prototype is a help tool to monitor the quality of the vital liquid in real time; it allows generating historical data to show its evolution in relation to time, and help the decision making to improve its quality. It is recommended to extend the testing period to make possible improvements.
