Protótipo do sistema de telemetria para aplicação no projeto do fórmula SAE elétrico

Abstract

SAE elétrico is a formula with the aim of providing engineering students with the opportunity to develop in practice a complete design of a formula car. One of the important pillars of the competition is related to the car's performance in dynamic tests where aspects related to the total functioning of the systems are observed, such as acceleration, braking, aerodynamics, safety and vehicle departure. With an important role, there is the need for telemetry applied to the electric car in order to extract and monitor data in real time, allowing the team ways to study and improve aspects related to the operation of the subsystems. In this context, the present work develops a prototype of a telemetry system focused on the transmission, storage and presentation of data in real time using the resources available through the internet of things (IOT). As a result, communication was obtained between two devices built with the Lora communication interface and the ESP 32 microcontroller, being, respectively, the transmitter that will be installed in the car and the receiver that will be in the competition box. The data collected and transmitted by the telemetry system is stored in a MongoDB database and presented in real time on a dashboard built in Node-Red. The results obtained meet the minimum requirements of the telemetry system, which is summarized in the transmission of information between the car and a local data server, opening a range of possibilities for new studies and improvements of the telemetry system.
