Resumo
O kart indoor é uma modalidade do automobilismo que vem ganhando espaço
nacionalmente e grandes investidores. É formado por equipes ou pilotos individuais, onde
em alguns campeonatos os pilotos se revezam durante a corrida e o restante da equipe
fica nos boxes monitorando e acompanhando todo desempenho dos karts e pilotos.
Nessa pesquisa percebe-se como uma oportunidade a proposição de um sistema de
telemetria de baixo custo, incorporada a um hardware proprietário para monitoramento
físico do piloto e o desempenho do kart.
Nesta proposta utilizou-se uma placa de desenvolvimento de hardware aberto já
disponível no mercado como o ESP32 LoRa com WiFi integrado, Bluetooth 4.2 e com
sensores acoplados. Esta placa de desenvolvimento tem como propósito neste projeto
validar a aplicação em tempo hábil e acelerar o desenvolvimento do código e realizar
testes iniciais em campo, corridas e treinos em kartódromos. Após as validações iniciais
será desenvolvido um hardware proprietário, robusto e de baixo custo.
O sistema de telemetria para corridas de kart consiste em um dispositivo com
display, sensores e armazenamento dos dados coletados. O dispositivo atua coletando
medidas como velocidade, temperatura ambiente, umidade, posição, tempo de volta e
duração da corrida. Uma pulseira conectada ao piloto faz o monitoramento do estado
físico, estresse e emoção do piloto durante a corrida, com sensores de temperatura,
pressão arterial, oxímetro e frequência cardíaca que envia os dados coletados via BLE
para o dispositivo no kart.
Foi obtido a validação do sistema para esta aplicação e o desenvolvimento de um
sistema robusto e de baixo custo para monitoramento do kart e dos pilotos durante as
corridas, obtendo informações essenciais para o melhor desempenho da equipe.
Indoor kart is a modality of motorsport that has gaining space nationally and attracting major investors. During the championships the support team stay in the boxes monitoring the performance of the karts and driver. Some competitions, called Endurance, races can last for hours and consider drivers and karts change in a same team, so a need for real-time monitoring is evident to coordinate and align strategies in shot time decisions, to looking for better results. Telemetry is the way to monitor the performance the indoor kart race. There are some telemetry systems available for this purpose, but they are costly or is limited in their application in addition they do not focusing on one important variable the drivers´ stress throughout the race. This research sees the proposition of a telemetry system with proprietary level hardware to monitor, through pilot's, and the kart's performance, as an opportunity. This information can contribute to the best performance of the team during the race. The proposal is to develop a board, with open hardware available on the market, such as the ESP32 LoRa with integrated Wi-Fi, Bluetooth 4.2, and with sensors attached. This board use will allow to speed up code development and initial field tests. After the initial validations, will be developed a proprietary, robust, and low-cost hardware. The telemetry system for kart racing will consist of Display device, sensors, and processing of collected data. In each kart, there will be a device with sensors to collect measurements such as speed, ambient temperature, humidity, position, lap time, and race duration. Bracelet for monitoring the driver's physical and mood performance during the race, through observations as temperature, blood pressure, oximeter, and heart rate sensors. These collected data will be sent via BLE to the device in the kart. This study was partially financed by the Reitoria PUC Campinas Brazil.
