Desenvolvimento de sistema de telemetria por rede LoRa para veículo protótipo de alta eficiência

Abstract

The telemetry systems are responsible for collecting and transmitting data, providing real-time information about the conditions of the monitored equipment, applied to automotive racing, it provides information about the performance of a vehicle and each of its internal systems. These systems allow the teams to make strategic decisions during competitions, based on the advantages mentioned above, this study details the development of a telemetry system for the prototype vehicle of the Pato a Jato team. The system studied simulates the reading of data from the sensors used in its motor through the CAN bus of the electronic injection module, and then its transmission is done through a point-to-point LoRa network, a topology defined due to its simplicity of implementation, low cost, and for not needing an internet connection for its operation. In the present study, the isolated development of each stage - data collection, radio frequency transmission and graphic display - is initially detailed, followed by total system integration and transmission tests for validation according to the conditions faced by the team in its operational tests and official competitions.
