Implementación de un sistema de telemetría para el monitoreo y gestión de consumo de energía eléctrica para el prototipo Shell-Eco marathon de la UPS sede Quito, campus Sur

Abstract

The problem consists of the need to establish a real-time communication system between an electric vehicle and those in charge of monitoring its operation during the Shell Eco-Marathon competition. This requires the implementation of a telemetry system in the prototype, which collects data such as speed, engine revolutions, battery charge-discharge times and temperature. The objective is to provide the pilot with real-time values so that he can make the right decisions and maximize the capacity and efficiency of the electric vehicle. This technical paper describes the creation of an experimental model of a telemetry system for the Shell Eco Marathon at the Salesian Polytechnic University. The system allows instant transmission and control of data acquired from different sensors, such as engine speed (RPM), vehicle speed, battery charge and discharge, and battery temperature. Process and display information for analysis. The technical implementation is based on the use of Arduino, a free hardware platform that collects and processes sensor signals. This project demonstrates the functionality of the telemetry system and its ability to improve the efficiency and safety of the prototype, which is why it is based on the use of an Arduino Mega, a piece of free hardware that collects all the signals from the sensors used. For the transmission and reception of data, we do it through a LoRa module, which facilitates the wireless connection between one or more various devices. The graphical interface was developed in LabVIEW, which allowed us to graphically visualize in real time the different sensors implemented in the experimental mode. In general, the results of the communication tests using the LoRa modules at distances of 200, 400, 600 and 800 meters demonstrate the efficiency and quality of the signal, the latter being a key factor in automotive applications. Although variations in RSSI values were observed, efficient and reliable transmission was achieved at all tested distances, which highlights the potential and effectiveness of LoRa modules in long-distance data transmission. These findings support the feasibility of using this technology in vehicle wireless communication systems, promoting safe and effective system operation.
