Diseño e implementación de un sistema de adquisición integrado de datos para el monitoreo inalámbrico de un vehículo fórmula SAE.

Abstract

The present degree work aimed the implementation of a telemetry system for the SAE vehicle of the faculty of mechanics at the Higher Polytechnic School of Chimborazo, which has a highly likely to participate in an SAE formula competition. At university level. Investigative, applicative and experimental methodologies were used through which the dynamic relationship between all of them could be verified during the investigation until the final implementation. The system consists of a motherboard that records the values of the different sensors for the quantities of interest. This, in turn, generates data processing printable on a NEXTION screen as an interface for the pilot and in the same way generates an interface in an APP, in which all SAE work personnel will know the status of the vehicle during the competition. Once the telemetry system has been developed, tests are carried out to validate the operation of the system with all its sensors mounted in the vehicle, where data on pressure, speed, revolutions per minute (RPM), GPS positioning, battery temperature, engine temperature its BMS are taken; conditioning these signals through development cards and giving all personnel the information of interest in the competition. The values obtained during the tests show how friendly and versatile the system for vehicle monitoring is. In short, it is seen that the telemetry system for monitoring variables of interest for the SAE formula vehicle behaves adequately in order to provide a necessary tool for monitoring the vehicle during SAE competitions.
