Dimensionamento e construção de um sistema multimicontrolado de dosagem e gestão básica de abastecimento da água c/uso da IoT

Abstract

In this project it was designed and built a system consisting of several devices that jointly perform the control of water dosage to be implemented in water supply stations through boreholes. Such system that we collectively call device is responsible for opening and closing the taps for filling 20 litres containers (adjustable to any other quantity) and large tanks in tank trucks. The system designed and implemented in prototype, showed to be able to open and close automatically with the click of a button on the control panel or by the introduction of a coin. The device was built based on microcontrollers, which are responsible for managing and controlling the basic processes. Flow sensors were used to measure the flow rate and determine the total amount of water that has passed through a given tap and the valves to open and close the taps. At a higher level, any subsequent management processes are based on computers using global Internet networks and the "cloud", to which data is channeled once produced, collected and processed by the microcontroller network. So, in short, the device designed and built in this work is able to count the total amount of water sold, send the sales reports through SMS, save sales data in a local database and in the cloud. Results of the efficiency analysis of the designed and built system compared with the systems currently in use proved that the proposed system presents more homogenous data with the standard deviation of 0.0086 against 0.0597 of the systems currently in use. Furthermore the proposed system showed an efficiency of 98.32% against 92.32% of the systems currently in use, implying that the proposed system is less wasteful of water and can save at least 6% of water sales. In summary, the results found in design, simulation and above all in the physical prototype implemented, show that the initial objectives were achieved.
