Implementação de telemetria no veículo da equipe cerrado Baja Sae

Abstract

This work involves the implementation of a sensing and telemetry system in the vehicle built by the Cerrado BAJA SAE team at the Federal University of Uberlândia. Initially, two available communication modules are analyzed. More specifically, the Xbee S2 and LoRa Ra-02 modules are compared to carry out communication between the vehicle and the box. The tests carried out involved the measurement of the maximum communication distance, reliability and data integrity, and the cost. As a result of this comparative study, the LoRa RA-02 was adopted to perform telemetry. Sensors are used to measure engine temperature and CVT (Continuously Variable Transmission), speed, fuel level, and vehicle inclination. Electronic circuits and codes for reading these sensors were developed throughout the present work. The collected information is treated and transmitted in an interface developed in the LabView software. The interface has a screen for presenting information in real-time, which allows the recording of a text file containing the received data. The interface also has a screen for graphical analysis of the vehicle's performance from the text file. Experimental results show the functioning of the developed telemetry system.
