Diseño de una red de comunicaciones para la medición y control del consumo de agua potable en tiempo real para la parroquia Yaruquíes perteneciente a la ciudad de Riobamba.

Abstract

The aim of the degree work was to design a communications network for the measurement and control of drinking water consumption in real time for the parish of Yaruquies belonging to the city of Riobamba. For the design of the network, the existing technology, factors, and devices that adjust to the requirements of the network were investigated, performing a simulation of the same, which allowed verifying the feasibility of implementing a prototype of the network. It consists of three stages: drinking water consumption measurement, data transmission, real-time monitoring control, for which an intelligent meter was implemented starting from the traditional meter incorporating a hall effect sensor and a Wi-Fi module ESP8266, which through wireless communication through the access point (AP) it publishes the data to the Broker MQTT server that is the intermediary of the communication. We worked with the Delphi Starter development package to create a User Graph interface where the consumption in real time is visualized and the MySQL database manager that stores the information. The efficiency of the network was determined by simulations and real tests with respect to connectivity, where the measurement device has reading errors of 0.06 liters, maximum coverage of 80 dBm and a bandwidth greater than 900 Kbps for a stable connection with the AP, the time of transmission and control of data throughout the network should not be greater than 2s. It is concluded that the communication network implemented together with the smart meter improves times and operation processes, in relation to conventional reading. It is recommended that for the smart meters, no connection to the network be lost, additional wireless routers should be implemented, especially in areas where the signal strength is lower.
