The vehicle fuel market has a very high demand and involves a significant financial volume, being a great target for fraudsters. Criminals alter fuel pumps in order to reduce the amount delivered to the customer. In this context, this work proposes a solution for metrological surveillance of fuel supply companies based on built-in vehicle sensors. A Kotlin API was developed to collect vehicle data from an OBD-II reader (On-Board Diagnostics) that establishes communication between the vehicle and a computational cloud established by a mobile application prototype (Android operating system). The application was developed to detect supply events and inform the user if the volume filled corresponds to the amount paid.
Resumo:O mercado de combustível para veículos possui uma demanda muito grande e envolve um volume financeiro significativo, sendo um grande alvo para fraudadores. Criminosos alteram as bombas de combustível com o objetivo de reduzir a quantidade entregue ao cliente. Nesse contexto, este trabalho propõe uma solução para a vigilância metrológica de empresas de abastecimento de combustível com base em sensores embutidos do veículo. Uma API Kotlin foi desenvolvida para coletar dados veiculares a partir de um leitor OBD-II (On-Board Diagnostics) que estabelece a comunicação entre o veículo e uma nuvem computacional estabelecida por um protótipo de aplicativo móvel (sistema operacional Android). A aplicação foi desenvolvida para detectar eventos de reabastecimento e informar ao usuário se o volume abastecido corresponde ao valor pago.
